Mosquito control professionals in Florida are turning to drones as part of their demanding work to find ways to control mosquito populations. The Keys has over 40 mosquito species; mosquitoes can transmit dengue fever, encephalitis, malaria, and dog heartworm. As the story goes, the first attempt in the Keys toward mosquito control was in 1929, with the setting up of a bat tower. The idea was that the bats would eat the mosquitoes. The bats flew away, but local town wits said the mosquitoes ate the bats. District Director Michael Doyle has invited several government agencies to a test flight on August 26. The drones, which resemble hawks in flight, are from Condor Aerial, of North Carolina; the company will send a rep to operate the test flight. According to the Condor Aerial website, the battery-powered drones are capable of up to 90 minutes of flight at one time. The battery-powered UAV in mind is the Maveric drone, outfitted with a shortwave infrared camera. The drone can fly 90 minutes at a time, is 2.2-pounds and 2.5-feet long. Condor Aerial, with a motto of “Providing Tomorrow’s Technology to Law Enforcement,” has been focused on providing aerial surveillance for law enforcement agencies but Doyle’s interest is to see what the short wave infrared camera can accomplish. According to KeysNet.com, Doyle said that deploying the camera may result in their being able to detect the shallow water areas which the department needs to identify. “If we can find the water, we can kill the mosquitoes. The real challenge is finding the water quickly enough,” Doyle said. Finding the water quickly means the district could move quickly to treat the areas with larvicide.

Florida is about to test how drones will do in tracking down mosquitoes. The Florida Keys Mosquito Control District, in its ongoing mission to make the job of killing mosquitos more efficient, is exploring unmanned aerial vehicles equipped with infrared cameras as one option for mosquito control. The goal is not to use drones to fight the insects but to use the UAVs to spot shallow-water pools where mosquitoes breed, up and down the Keys. Once the pools are found, ground action would begin, with attacks on these pests at the larval stage with larvicides.last_img read more

Xray observations reveal new details about the solartype star HD 209458

first_imgChandra HRC-I image of HD 209458. Credit: Czesla et al., 2017. Located some 160 light years away from the Earth, HD 209458 is a G-type main sequence star very similar to our sun. It has a radius of about 1.2 solar radii and is approximately 13 percent more massive than the sun. The star is orbited by a so-called “hot Jupiter” exoplanet, circling it every 3.5 days at a distance of about 0.047 AU.HD 209458 has a relatively high rotation velocity. With a rotation period of 14.4, it rotates at about twice the solar rate. However, it is a rather inactive star, and despite its critical role in planetary mass loss, the star’s X-ray spectrum and luminosity have not yet been thoroughly studied and remain controversial. Previous measurements of the star’s soft X-ray flux are based on the available data from ESA’s X-ray Multi-Mirror Mission (XMM-Newton) spacecraft, which suffer from significant background contamination, complicating the analysis of HD 209458.So a team of astronomers led by Stefan Czesla of the University of Hamburg, Germany, has complemented the XMM-Newton data with new observations from NASA’s Chandra X-ray Observatory. The combined analysis of the data provided by these two spacecraft allowed the researchers to obtain more details about X-ray properties of HD 209458.”We carry out a detailed analysis of our new Chandra HRC-I data, the available archival XMM-Newton observations and, finally, present a combined analysis of both data sets,” the authors wrote in the paper. The team’s analysis includes XMM-Newton data provided by observations conducted in 2000 and 2006, and a new Chandra dataset obtained thanks to observations carried out in June 2016. All these data deliver crucial information about HD 209458’s coronal X-ray emission and planetary irradiation.According to the study, HD 209458 was confirmed to be an X-ray source. The analysis shows that the star has a coronal temperature of about one million K and an emission measure of approximately 70 quindecillion cm-3, which indicates an X-ray luminosity of about 1.6 octillion erg s-1 in the 0.124-2.48 keV band. The researchers compared these results with the properties of other known stars, including our sun. “With respect to coronal temperature, HD 209458 appears to be comparable to the inactive sun or Cen A,” the paper reads. Furthermore, the team noted that the level of planetary atmospheric irradiation is sufficient to drive planetary evaporation at a rate of a few times ten billion g s-1.”At this level of activity, the planetary high-energy emission is sufficient to support mass-loss at a rate of a few times 1010 g s-1,” the researchers concluded.

Credit: X-ray: NASA/CXC/ASTRON/B.Stappers et al.; Optical: AAO/J.Bland-Hawthorn & H.Jones More information: Mode changing and giant pulses in the millisecond pulsar PSR B1957+20, arXiv:1807.01713 [astro-ph.HE] arxiv.org/abs/1807.01713AbstractMany radio pulsars have stable pulse profiles, but some exhibit mode changing where the profile switches between two or more quasi-stable modes of emission. So far, these effects had only been seen in relatively slow pulsars, but we show here that the pulse profile of PSR B1957+20, a millisecond pulsar, switches between two modes, with a typical time between mode changes of only 1.7,s, the shortest observed so far. The two modes differ in both intensity and polarization, with relatively large differences in the interpulse and much more modest ones in the main pulse. We find that the changes in the interpulse precede those in the main pulse by ∼25 ms, placing an empirical constraint on the timescale over which mode changes occurs. We also find that the properties of the giant pulses emitted by PSR B1957+20 are correlated with the mode of the regular emission: their rate and the rotational phase at which they are emitted both depend on mode. Furthermore, the energy distribution of the giant pulses emitted near the main pulse depends on mode as well. We discuss the ramifications for our understanding of the radio emission mechanisms as well as for pulsar timing experiments.

Canadian astronomers have identified mode changing and giant pulses in the millisecond pulsar known as PSR B1957+20. It is the first time when mode changing mechanism has been observed in a millisecond pulsar. The finding is detailed in a paper published July 4 on the arXiv pre-print server. Radio pulsars showcase various variability in emission ranging from extremely short bursts like giant pulses to long-term changes in their emission profiles. Some of them exhibit even mode changing where the emission profile switches between two or more quasi-stable modes of emission. To date, mode changing has been only observed in normal pulsars.However, a recent study conducted by a team of astronomers led by Nikhil Mahajan of the University of Toronto in Canada, shows the mode changing process could be also present in millisecond pulsars, as they observed that the pulse profile of pulsar PSR B1957+20 switches between two modes. Discovered in 1988, PSR B1957+20, also known as the “Black Widow Pulsar”, is a 1.6 ms eclipsing binary millisecond pulsar in the constellation Sagitta. It orbits with a brown dwarf companion with a period of 9.2 hours with an eclipse duration of approximately 20 minutes. Mahajan’s team observed this pulsar for over nine hours in four daily sessions between June 13 and 16, 2014 at the Arecibo Observatory in Puerto Rico, what resulted in uncovering new insights into its behavior.”Here, we show that the millisecond pulsar PSR B1957+20 shows mode changing, and that the properties of the giant pulses that we found earlier (in the same data; Main et al. 2017) show correlations with the modes,” the paper reads.According to the study, PSR B1957+20 switches between two modes, with a typical time between mode changes of only 1.7 seconds, or approximately 1,000 pulse periods. This is the shortest time between mode changes in pulsar observed so far by astronomers as in regular pulsars these timescales range from minutes to even weeks.The two modes observed in PSR B1957+20 differ in both intensity and circular polarization. They were tagged “high” (more energetic) and “low” (less energetic). The researchers found that the pulsar is in the high mode about 60 percent of the time and in the low mode about 35 percent of the time. The remaining 5 percent of the time was assigned to transition between the two modes.Furthermore, observations conducted at the Arecibo Observatory allowed the astronomers to detect 1,715 giant pulses in PSR B1957+20. They found that the distribution of giant pulses with pulse phase is correlated with mode changing.”We also find that the properties of the giant pulses emitted by PSR B1957+20 are correlated with the mode of the regular emission: their rate and the rotational phase at which they are emitted both depend on mode,” the researchers wrote in the paper.However, the authors of the study noted that additional follow-up observations of PSR B1957+20 at different frequencies are needed to shed some light on the causes of mode changing and giant pulses in this pulsar. © 2018 Phys.org Astronomers observe unprecedented detail in pulsar 6,500 light-years from Earth Explore furtherlast_img read more

Heated crystal flakes can be sewn into clothing for thermotherapy

Credit: Park et al. ©2019 American Chemical Society The researchers, led by Chong Min Koo, at the Korea Institute of Science and Technology and Korea University, and Cheolmin Park, at Yonsei University, have published a paper on the shape-adaptable MXene heater in a recent issue of ACS Nano.In recent years, researchers have been investigating different materials to be used as flexible, wearable heaters. Although materials such as carbon nanotubes and graphene have excellent electrical and optical properties, it has been challenging to process them for use in applications.A newer material, MXene was first introduced in 2011 by researchers at Drexel University. MXene is a 2-D crystalline material that exhibits metal-like conductivity and strong electric-to-heat conversion behavior. It can also be easily processed into thin films and fabrics.”We were able to develop novel light-weight, cost-effective but high performance electrical heaters based on emerging 2-D materials of MXene, which are suitable for wearable and on-body applications,” Park told Phys.org. “Several candidates for the purpose have been proposed, based on carbon nanomaterials, but they are restricted by either their poor processability or low electrical conductivity involving harmful and toxic chemicals. We resolved these issues with solution-processed MXene flakes.”In the new study, the researchers first used MXene flakes to fabricate a transparent thin-film heater. Under an applied 15 V, the heater’s temperature increased at a rate of 8°C/second to reach a maximum of 120°C (248°F). By submerging the heater in liquid nitrogen for 5 minutes, the researchers demonstrated that the heater could function as a defroster, rapidly removing the frost on its surface under 12 V. As a demonstration of its high flexibility, the heater could be folded at a 90° angle without any increase in resistance, and continued to function even when folded in half, although with greater resistance.The researchers also demonstrated that the MXene flakes can be used to make heated fabric. To do so, the researchers treated commercial polymer threads with a coating to enhance their electrostatic interaction with the MXene flakes. Then they dipped the threads into a water solution containing MXene flakes. The electrostatic interaction between the positively charged threads and negatively charged flakes caused the flakes to self-assemble onto the individual fibers, turning the white threads black in the process.The MXene-coated threads were then sewn together with cotton to make heated clothing. Under a small voltage, each MXene flake acted as a tiny heater. By controlling the voltage, the researchers could gradually raise the temperature of cold skin back to normal body temperature without damage to the skin. In future applications, the heated clothing could be powered by conventional batteries or alternative power sources.”Potentially, our heater can be powered by the energy stored in batteries and/or supercapacitors from a variety of emerging renewable energy sources, such as wearable solar cells, triboelectric energy generators, and so on,” Park said.The researchers expect that the robust, flexible heated clothing could be useful for healthcare thermotherapy and monitoring, among other personal applications.”Since the MXene flakes we developed with the solution process are highly conductive and optically transparent, a variety of applications are possible, in particular, requiring transparent electrodes,” Park said. “Examples include the development of mechanically flexible and thus wearable organic light emitting diode displays, photodetectors, and transparent touch and/or pressure sensors.” More information: Tae Hyun Park, Seunggun Yu, et al. “Shape-Adaptable 2D Titanium Carbide (MXene) Heater.” ACS Nano.

Mass estimated for two binary pulsars

first_img © 2019 Science X Network Mass constraints for PSR J1949+3106. Image credit: Zhu et al., 2019. Citation: Mass estimated for two binary pulsars (2019, July 18) retrieved 18 August 2019 from https://phys.org/news/2019-07-mass-binary-pulsars.html By performing timing observations, an international group of astronomers has measured the mass of two binary millisecond pulsars designated PSR J1949+3106 and PSR J1950+2414. The results could be essential in order to unveil the evolutionary status of these two objects. The research is detailed in a paper published July 11 on arXiv.org. Explore further Gamma-ray pulsations detected from the pulsar J0952−0607 Pulsars are highly magnetized rotating neutron stars that emit beams of electromagnetic radiation. The most rapidly rotating pulsars, with rotation periods below 30 milliseconds, are known as millisecond pulsars (MSPs).Astronomers believe that MSPs are formed in binary systems when the initially more massive component turns into a neutron star that is then spun up due to accretion of matter from the secondary star. To date, more than a half of known MSPs have been found to have stellar companions.Nearly 200 pulsars have been discovered by PALFA, a large-scale survey for radio pulsars at 1.4 GHz using the Arecibo 305-meter telescope and the ALFA multibeam receivers. Recently, a team of astronomers led by Weiwei Zhu of the Max Planck Institute for Radio Astronomy in Bonn, Germany, decided to take a closer look at two MSPs from this survey, namely PSR J1949+3106 and PSR J1950+2414, detected in 2012 and 2013 respectively. The main aim of the study was to measure the proper motions of these two systems more precisely and to measure masses of these objects and their companions.”In this paper, we present the results of timing observations of PSRs J1949+3106 and J1950+2414, two binary millisecond pulsars discovered in data from the Arecibo ALFA pulsar survey (PALFA),” the astronomers wrote in the paper.Initial observations of the two pulsars made by Zhu’s team confirmed that with adequate timing data, it could be possible to perform accurate mass measurements. By analyzing the dataset from Arecibo Observatory and from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the astronomers were able to conduct precise calculations of proper motions of both pulsars, what resulted in uncovering the masses of the two systems.According to the paper, the pulsar PSR J1949+3106 was found to have a mass of about 1.34 solar masses, while its companion has an estimated mass of approximately 0.81 solar masses. The observations revealed that PSR J1950+2414 is more massive than PSR J1949+3106, which has a mass at a level of around 1.5 solar masses. However, its companion turned out to have a relatively low mass—only about 0.28 solar masses.The derived masses, together with calculations of proper motions, allowed the team to draw initial conclusions regarding the evolutionary history of both objects.”PSR J1949+3106 is likely the product of a low-kick supernova; PSR J1950+2414 is a member of a new class of eccentric millisecond pulsar binaries with an unknown formation mechanism,” the researchers concluded.

Red wine offsets impact of fat diet

first_imgThe findings, published in the journal Frontiers in Physiology, point to the health benefit of resveratrol, which occurs naturally in blueberries, raspberries, mulberries, grape skins and consequently in red wine. In previous animal studies, resveratrol has already shown to increase the life span of mice and slow the onset of diabetes. In one study, it mirrored the positive effects of aerobic exercise in mice, which were fed a high fat/high sugar diet. Also Read – ‘Playing Jojo was emotionally exhausting’For the current study, J.P. Hyatt, associate professor at Georgetown University and his team of researchers fed a control group of rhesus monkeys a healthy diet and another group a high fat/high sugar diet, half of which also received a resveratrol supplement and half of which did not. The researchers wanted to know how different parts of the body responded to the benefits of resveratrol – specifically the muscles in the back of the leg. Three types of muscles were examined: a “slow” muscle, a “fast” muscle and a “mixed” muscle. The study showed that each muscle responded differently to the diet and to the addition of resveratrol.  Also Read – Leslie doing new comedy special with NetflixOf the three lower hind leg muscles analysed for this study, the soleus was the most effected by the high fat/high sugar diet and also most effected by the resveratrol supplements. This may be partially due to the fact that, on a daily basis, it is used much more than the other two muscles.While these results are encouraging, the researchers stressed that the importance of a healthy diet cannot be overemphasised.last_img read more

How viewers cant distinguish real 3D films from artificial ones

first_imgIt seems to be very difficult for viewers to tell the difference between real and artificially rendered 3-D films, according to new research. Examining the effects of various technologies, the researchers found that it plays virtually no role in the viewer’s experience whether a 3-D film was originally produced as such or whether it was later converted from 2-D to 3-D using algorithms as, for example, is the case with new 3-D televisions. “That is surprising when you consider how much time and money goes into producing real 3-D films,” said primary author of the study who did a research on this unique topic. In the study, participants were shown six short film sequences, two each from the categories horror, action, and documentary films.  Also Read – Best Telugu shows to watch on ‘Viu’While there were no detectable differences when it came to the two 3-D technologies, there was divergence in the way that the three individual categories were assessed.The 108 participants of the study were given 3-D glasses and had to rate the impressions made on them by the film segments.  For example, the basis on whichthey were supposed to tell their experience was that they had to say whether the story in the film drew them in or in another case whether they were impressed by the technological aspects of the film, what type of emotion or excitement did they experience while watching the film. Also Read – American Crime Story 3 to chronicle Clinton’s impeachmentAnother category was  whether they felt any sort of queasiness due to the camera movements. They were also asked what they thought of the main characters in the films.According to the results, published in the journal ‘Displays’, 3-D films essentially inspire stronger feelings of being drawn into the story than 2-D films. However, 3-D films also more often cause slight nausea because of what can be described as ‘motion sickness’.  The researchers also discovered that the viewers found 3-D technology particularly interesting for action and horror films, but less for documentaries.It was of virtually no significance whether the 3-D aspect of the film was real or an algorithmic conversion, the study showed.last_img read more

All the massage moves in this deep tissue therapy are based on Taichi – credited as effective treatment for relieving pain and uses energy rather than force. We as sports massage specialists are practitioners and also do psychotherapy along with massage to understand the issues of the patient and assist in recovery of the affected muscle, symptomatically,” said Mel Cash, the founder and principal tutor of the London School of Sports Massage with over 30 years of teaching experience.

And hence, the therapists at The Imperial Spa are highly trained in fitness/sports massage to understand the needs of the resident guests and apply pressure and pain as per their physical issues. They use the right amount of strength and control to make the recovery faster and smoother. With regular sessions, the international and domestic guests who stay at The Imperial feel healed to a great extent and come back for more sessions.

When we sit for long hours our abdominal muscles are used inefficiently which leads to tightening of back muscles and eventually causes back pain. Massage helps in evading the symptoms but along with that posture and lifestyle changes are also a must which includes reducing weight and increasing mobility. Even for neck pain, sports massage tears the symptoms and relives any unpleasant tension and pain. “I would suggest that one should also focus on strengthening the abdominal muscles in the right manner to increase their core stability for supporting the back but beware, too much strengthening and tightening can cause trouble. For instance, in men with a six-pack abs, it can lead to breathing issues and in women with tight pelvic muscles formed due to excessive Pilates, can cause urinary incontinence. So, everything should be in balance to create a better quality of life,” explained Mel.last_img read more

They have achieved a style that is both ancient and modern at the same time. Dakshinamoorthy’s distortion of the human figure is influenced by tribal and folk art. He is well-known, for his charismatic granite sculptures of the female form, chiselled in an engaging, stylistic demeanour that is unquestionably cubist. Whereas, the themes and subjects of P Gnana paintings and sculptures are of a universal nature, it is something that comes uncultivated and straight from his heart”.last_img read more

Relief for New Town residents App to locate empty slots for best

first_imgKolkata: Has it become a bit frustrating for you to park your vehicles in New Town because you fail to find a slot in the parkingplace? Don’t worry, the New Town Kolkata Development Authority (NKDA) is going to put in place one of the most advanced mechanisms in New Town by ensuring that not a single slot for parking is left empty. The New Town Kolkata Development Authority is coming up with a smart parking app which will help people identify the empty slots for cars and maximum use of the parking place. The whole operation would be done through a sensor system. The new system will be felicitated by an agency which will be engaged by the NKDA. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataDebashis Sen chairman of the NKDA on Wednesday said that they are planning to introduce a smart parking app only to ensure that none of the slots in a parking area remains empty. Often it was found that people face inconveniences as the empty slot could not be navigated properly. The slots at the farthest corner remain empty due to the manual parking system. He was talking at a symposium “Infrastructure Development and Management in Future Cities” organised by RCG School of Infrastructure Design and Management (RCGSIDM), IIT Kharagpur at a city hotel. Also Read – Lightning kills 8, injures 16 in stateThe sensor aided system will help the driver to reach to the slot demarcated for him/her. As the people at the parking places go by the toll data at the gate they cannot determine where exactly the empty slot is situated. The new system will help people to reserve the empty slot and easily access it. A demo has already been given by a startup company, Sen maintained. He also said that they are bringing in new innovations to reduce the road accidents in New Town. There will be a new mechanism operated with the help of the CCTVs to identify and intercept the errant drivers. A real time alert will be delivered to the traffic sergeant in the area the accused driver is heading to. If any irrational behavior is detected on the part of the drivers, an alert would be triggered and the details of the vehicle would be shared with the on duty traffic police officers. Sen also reiterated how E-governance has been given a paramount importance and services are being provide to the people online. The NKDA is also introducing online sanction of building plans which is the first in the country. Online filing of taxes would be conducted. Many graduate youths are being trained on how to help elderly persons to submit their taxes online. The youths will be provided incentives.last_img read more

Cancer therapy may up heart disease risk in men

first_imgA cancer therapy — considered to be gold-standard treatment — is causing men to lose muscle mass and gain fat, putting them at increased risk of other disorders like cardiovascular disease, diabetes and osteoporosis, a study has found. Researchers showed men treated with hormone therapy for prostate cancer often had a dangerously high fat to muscle ratio. The study said while the five-year survival rate for Australian men with prostate cancer was now 95 per cent, side-effects from the intense treatment regimen were becoming an increasing concern. Also Read – Add new books to your shelf”Men diagnosed with prostate cancer are now living longer due to medical advancements, but are susceptible to a range of treatment side-effects,” said Patrick Owen, lead author of the study published in the Journal of Cachexia, Sarcopenia and Muscle. “Prostate cancer survivors are now more likely to die from other conditions, such as cardiovascular disease, than prostate cancer, which may in part be due to our inability to detect and subsequently treat side-effects of therapy,” Owen said. Also Read – Over 2 hours screen time daily will make your kids impulsive”The amount of muscle we have relative to fat is one of the biggest indicators for diabetes risk, decreased physical function needed to complete daily tasks, and lots of other adverse health conditions,” he added. The research examined the muscle and fat in 70 men treated with hormone therapy for prostate cancer compared to 52 men with prostate cancer not treated with hormone therapy and 70 healthy men of a similar age. It found men treated with hormone therapy for prostate cancer had the same amount of total muscle mass compared to other men in the study, but four to six kilograms more fat mass. “When men are diagnosed with advanced prostate cancer they are often treated with hormone therapy to reduce their testosterone levels, which discourages cancer growth. This is considered the gold-standard of treatment,” he further said. “It puts men through the equivalent of menopause. There’s a loss of muscle and bone, they gain fat, and even start to have hot flushes,” he stated. While men with prostate cancer treated with hormone therapy may have the same or greater absolute muscle mass than non-treated and healthy men, it’s not as functional as the same amount of muscle in otherwise healthy weight men. Owen said that he hoped his recent research would encourage more clinicians to test their male patients for muscle mass relative to body fat. Lifestyle interventions that could be used to help men with prostate cancer reduce body fat and increase muscle.last_img read more

The first Soviet probe sent to Mars moon Phobos failed due to

first_imgRaces were not uncommon during the Cold War. With the Soviet Union and the United States squaring off against one another, worried about an all-out war breaking out, both governments pushed for technological accomplishment. There was a race for nuclear superiority, a race for technological supremacy and most famously, the Space Race. Both sides pushed to be the first to get satellites out and later, to have manned flights to space. The ultimate victory in this race would be when the United States was the first country to have a man walk on the moon.While space travel might seem unnecessary, especially in light of nuclear war, it’s important to know that these expenditures led to tremendous technological development. Rocketry advances would lead to improved land-based missile functions, making the Space Race more than just chest puffing between two nations. Indeed, it was a matter of national security.People atop the Berlin Wall near the Brandenburg Gate on 9 November 1989. Photo by Sue Ream CC BY 3.0By the late 70s, the Space Race had slowed down, with America clearly in the lead. The Soviets, having achieved tremendous early success with Yuri Gagarin being the first man in space, were unable to achieve getting one of their own to the moon and would eventually abandon their attempts. Yet, even without the fierce competition, the Soviet Union still worked to develop their space program.Before the fall of the Berlin Wall and the dismantling of the Soviet Union, there was one disastrous attempt to send a satellite into orbit around the moons of Mars: Phobos and Deimos. The year was 1988 and the Phobos Program was implemented so that the Soviets would be able to study Mars, Phobos and Deimos. The plan was to launch their first satellite, Phobos 1, to achieve an elliptical orbit around Mars.Illustration of the Phobos 1 spacecraft.The satellite itself was quite impressive. Designed to operate in three separate phases of its flight, Phobos 1 was extremely heavy. In fact, at the time, it was heavier than any other vehicle that had been launched into space.Little was known about Mars in terms of scientific data. With Phobos 1 launched, there was great hope of being able to extract plenty of information that would increase the Soviet’s knowledge about Mars, but an unfortunate and entirely avoidable accident caused the early demise of Phobos 1’s mission.NASA Apollo moon landings conspiraciesCommands were sent from the ground to the satellite, in order to give it various orders such as adjusting trajectory or releasing its hopper. These commands were required to be proofread in order to ensure that there were no errors in the code.Phobos, moon of Mars and primary object of study for the Phobos 1 spacecraft.The smallest error in the code could cause problems for the satellite and since it was traveling far, far from earth, there would be no way to manually fix the problem. Normally, extra care was employed when it came to checking codes for errors. Yet, in the case of Phobos 1, impatience cost the Soviets the entire mission.On September 2, 1988, a technician finished working on the key-command with a single error on it – a missing hyphen. Normally, the technicians were required to place the commands into a computer which would check for errors, but the computer was down for maintenance. Instead of waiting for the computer to get back up and running, the technician decided that the code was fine and transmitted the key command to Phobos 1.Commemorative postage stamp, Phobos 1.The faulty code caused Phobos 1 to believe that its mission was over. The satellite then shut down all of its systems, leaving the satellite useless and without function. A single mistake in a line of code singlehandedly disrupted the Phobos mission, leading to a crisis back on Earth within the Phobos Program.The relative sizes of Deimos and Phobos as might be seen from the surface of Mars, compared to the relative size in the sky of the Moon as seen from Earth.The Soviets, not known for their human rights record, wanted to investigate the mistake and find the person who was responsible for such an egregious failure. However, the Phobos Program was still running and the Phobos 2 mission was still in operation. There was fear that punishing the failed Phobos 1 team would lead to a decrease in performance and morale in the Phobos 2 team. So, the investigation was delayed until after Phobos 2 was completed. Eventually, the ground control leader was released from his duties, but no further punishments were meted out.Read another story from us: Mad conspiracy theories that turned out to be truePhobos 2 was nominally more successful than Phobos 1, at least reaching its destination before an onboard computer system failed, losing contact with the Soviets. The space race would definitely end with the dissolution of the Soviet Union, when Russia would take over the space program and begin cooperation with the United States, leading to even more progress on the space front.Andrew Pourciaux is a novelist hailing from sunny Sarasota, Florida, where he spends the majority of his time writing and podcasting.last_img read more

How the Corpse of an AllTime Loser Became a MoneyMaking Sensation

first_imgElmer McCurdy is a man who had more fun dead than he ever did alive. The failed train robber—or rather, his corpse—would spend sixty-some years crisscrossing the country, popping up everywhere, from haunted houses to B-movies. McCurdy was born in Maine, in 1880, but moved to the Midwest at age twenty, and became something of a drifter. He had a fondness for hooch and a hard time holding down a job, so he decided to give the Army a try.During his stint in the military, McCurdy developed a fondness for nitroglycerin demolitions (read: blowing stuff up). He figured it was a handy skill to have, particularly for his next line of work: robbing banks and trains. Unfortunately, McCurdy never quite figured out the formula, which lead to disastrous (and funny) results.Elmer McCurdyCase in point: Trying to rob a Pacific Express Company train, McCurdy went a little heavy on the nitro and ended up melting some $4000’s worth of silver into a big metallic blob.Another miscalculation would end up costing McCurdy his life. In October of 1911, near Okesa, Oklahoma, the outlaw and his cohorts attempted to rob another train, after hearing it was carrying $400,000 in cash.Unfortunately, they mixed up the train schedules and ended up working over a passenger train instead. Their take: two jugs of whiskey, a revolver, a coat, and the train conductor’s watch.Train Robbery(Embarrassing, to be sure: a newspaper would refer to the paltry payoff as “one of the smallest in the history of train robbery.”) McCurdy returned to the ranch where he’d been staying, knocked back a couple of strong ones, and fell asleep in a hayloft, not realizing that the Okesa police were hot on his trail. Later that night, McCurdy was killed in a shootout.His body was taken to a funeral home in nearby Pawhuska. Joseph L. Johnson, the owner, embalmed the body with an arsenic-based preservative employed back in the day to keep the dead, well, intact, while searching for the next-of-kin.Besides, Johnson wasn’t about to bury the remains until he was paid, dang it! When it became clear that no one would be coming to claim the body, the crafty undertaker concocted a plan: turning McCurdy’s corpse into a money-making exhibit. He dressed the lifeless body, shoved a gun in his hands, and propped it up in the corner of his funeral home. Morbid? You bet. But curiosity seekers came from miles around to gape at “The Bandit Who Wouldn’t Give Up,” each person placing a nickel in McCurdy’s mouth. The attraction become so lucrative, Johnson refused to part with his cadaver cash cow.Related Video: Archaeologists unveil 3,000 year old Tomb in LuxorBut in 1916, two men contacted the local sheriff, claiming to be McCurdy’s long lost brothers. They got permission to take custody of the body and ship it to San Francisco for a proper burial. Actually, they were James and Charles Patterson, who ran a traveling carnival. And thus, the strange odyssey of Elmer McCurdy’s corpse began—with the Patterson brothers exhibiting McCurdy as a sideshow curiosity throughout Texas. In 1922, the operation was sold to Louis Sonney, who displayed the corpse in his traveling “Museum of Crime” show, which featured famous outlaws (albeit, wax replicas), such as Jesse James.Jesse JamesFor over sixty years. McCurdy’s corpse changed hands again and again. In 1933, it was acquired by director Dwain Esper to promote his B-movie Narcotic. (The corpse was exhibited in the lobby of theaters as a “dead dope fiend,” to demonstrate the dangers of drugs.)Other stops: haunted houses, an amusement park near Mount Rushmore, and even low-budget horror flicks (including an appearance in David F. Friedman’s She Freak.) In 1968, it was sold to the Hollywood Wax Museum. (And no, most were unaware that the mannequin was very real.)In 1976, the McCurdy Magical Mystery Tour arrived at its last stop: the Nu-Pike amusement park in Long Beach, California. During an on-location filming of The Six Million Dollar Man, a prop man, checking out the funhouse, moved what was assumed was a wax mannequin, hanging from the gallows. Imagine his surprise (not to mention abject horror) when the mannequin’s arm snapped off…revealing human bone!The PikeThe corpse ended up in the coroner’s office, where an autopsy was performed. The body wasn’t in the best of shape—after all, it had been through a lot. Not only had it petrified and shrunk to about fifty pounds, but it was covered in wax and layers of orange fluorescent paint (it gave off a nice glow for displays). But the examination did offer some clues.Among them, the body was that of a human male, who had died of a gunshot wound to the chest. The bullet that caused his fatal wound was removed during the original autopsy, but the bullet jacket remained, which revealed the era in which the mystery man had been killed. The real motherlode: Lodged inside the mouth was a 1924 penny and ticket stubs to the Museum of Crime. That allowed officials to finally trace his identity.The story of McCurdy’s remarkable journey found its way into newspapers and onto TV. Funeral homes called the coroner’s office, offering to give the remains a permanent home, but L.A. officials decided to hang onto the body, in case a living relative came forward to claim it.Read another story from us: The Darker Side of how P.T. Barnum Became “The Greatest Showman”When it became clear that wasn’t going to happen, Fred Olds, representing the Indian Territory Posse of Oklahoma Westerns, offered to let McCurdy’s body be buried in the Summit View Cemetery in Guthrie, Oklahoma, next to another train-robbing outlaw, Bill Doolin. Still, officials weren’t taking any chances. To ensure that McCurdy’s driftin’ days were over, concrete was poured over the casket before the gravesite was sealed.last_img read more
