(image) Images taken by a NASA Mars orbiter indicate that a missing European space probe fell to the Red Planet's surface from a height of 2 to 4 kilometers (1.2 to 2.5 miles) and was destroyed on impact, the European Space Agency said on Friday. The disc-shaped 577-kg (1,272 lb) Schiaparelli probe, part of the Russian-European ExoMars program to search for evidence of life on Mars, descended on Wednesday to test technologies for a rover that scientists hope to send to the surface of the planet in 2020. The U.S. space agency's Mars Reconnaissance Orbiter, which has been circling Mars for about 10 years, took low-resolution pictures that show a bright spot that ESA believes is the 12-metre parachute that Schiaparelli used to slow down.

(image) By Will Dunham WASHINGTON (Reuters) - A bottom-dwelling, mud-grubbing, armored fish that swam in tropical seas 423 million years ago is fundamentally changing the understanding of the evolution of an indisputably indispensable anatomical feature: the jaw. "Now we know that one branch of placoderms evolved into modern jawed vertebrates," said study co-leader Zhu Min, a paleontologist at Chinese Academy of Sciences' Institute of Vertebrate Paleontology and Paleoanthropology.

(image) Spiders can control the tension and stiffness of their webs to optimize their sensory powers, helping them locate and identify prey as well as partners, according to researchers at Oxford University. "Spiders use vibrations not only from prey which is caught in their web, where obviously it's important that they know ...where it is and what it might be," researcher Beth Mortimer told Reuters. "But vibrations are also important in courtship ... A lot of males will actually generate a very specific kind of musical pattern which the females can use to determine not only that they're a male but they're the right species and whether she might want to mate with them as well." Spiders can also use the information to assess their web's condition, she said.

(image) By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - NASA's Juno spacecraft lost its main computer and science instruments shortly before it was due to make an orbital pass near Jupiter on Wednesday, scuttling highly anticipated close-up observations of the largest planet in the solar system. The U.S. space agency said the glitch followed an unrelated problem last week that prompted it to skip firing Juno’s braking engine, to steer the probe into a tighter regular orbit around Jupiter. Juno's computer restarted after Wednesday's shutdown and the spacecraft was "healthy," NASA said in a statement.

(image) At last night's presidential debate, Donald Trump said abortions could happen "on the final day" of a pregnancy if Hillary Clinton becomes president, but experts say this is very unlikely and does not accurately reflect the reality of abortions in the United States. However, an abortion so late in pregnancy is "incredibly unlikely," said Elizabeth Nash, the senior state issues manager at the Guttmacher Institute, a reproductive health research organization. "That just isn't the experience around abortion that women have" in the United States, Nash said.

(image) Wealthy people appear to spend less time looking at other human beings, compared with how much time people in lower social classes look at others, according to a new study that used Google Glass headsets to track people's gazes. Because the time people spend looking at something may be related to how much motivational relevance the object or person holds, the "findings make a compelling case that social classes differ in their judgments of other people's significance," the researchers wrote in their paper, published Oct. 3 in the journal Psychological Science. In the study, the researchers asked 61 people to wear a Google Glass headset while walking around in New York City.

(image) People who regularly smoke large amounts of marijuana may be more susceptible to bone fractures than people who don't use the drug, according to a new study conducted in the United Kingdom. Researchers also found that the people in the study who used marijuana regularly tended to have thinner bones than the people who did not use pot. Having thinner bones might put people at higher risk for osteoporosis, a condition in which a person's bones become brittle and fragile, the researchers said.

(image) Early Monday (Nov. 23), the private spaceflight company Blue Origin made a major stride in the pursuit of fully reusable rockets, when it launched an uncrewed vehicle into space and then soft-landed the rocket booster on the ground. "It was one of the greatest moments of my life," said Jeff Bezos, Blue Origin's founder, speaking about the landing in a press briefing yesterday (Nov. 24). "And my teammates here at Blue Origin, I could see felt the same way.

Like most Americans, NASA astronauts Scott Kelly and Kjell Lindgren have Thanksgiving (Nov. 26) off, and they'll spend the day aboard the International Space Station (ISS) watching football and enjoying a turkey-centric feast, agency officials said. Kelly and Lindgren gave viewers a look at that feast in a special Thanksgiving video this week, breaking out bags of smoked turkey, rehydratable corn, candied yams and potatoes au gratin.

(image) The ExoMars 2016 mission is in business despite the apparent failure of its lander to touch down softly on the Red Planet Wednesday (Oct. 19), European Space Agency (ESA) officials stressed. The lander, known as Schiaparelli, seems to have deployed its parachute too early and fired its thrusters for an insufficient amount of time as it streaked through the Martian atmosphere Wednesday, ESA officials said. As Schiaparelli was experiencing its "six minutes of terror" descent, the second part of the ExoMars 2016 mission, the Trace Gas Orbiter (TGO), was firing its main engine for more than two hours in a crucial orbit-insertion burn.

(image) Planet Nine's days of lurking unseen in the dark depths of the outer solar system may be numbered. The hypothetical giant planet, which is thought to be about 10 times more massive than Earth, will be discovered within 16 months or so, astronomer Mike Brown predicted. "I'm pretty sure, I think, that by the end of next winter — not this winter, next winter — I think that there'll be enough people looking for it that … somebody's actually going to track this down," Brown said during a news conference Wednesday (Oct. 19) at a joint meeting of the American Astronomical Society's Division for Planetary Sciences (DPS) and the European Planetary Science Congress (EPSC) in Pasadena, California.
Wed, 19 Oct 2016 23:33:48 -0400Scientists have found 500 seabed vents bubbling methane into the Pacific Ocean off the United States, roughly doubling the number of known U.S. seeps of the powerful greenhouse gas, a study showed on Wednesday. "It appears that the entire coast off Washington, Oregon and California is a giant methane seep," Robert Ballard, who is famed for finding the wreck of the Titanic and has now discovered the 500 new seeps, said in a statement. Nicole Raineault, Director of Science Operations with Ballard's Ocean Exploration Trust, said it was unknown how long the seeps had been active, what triggered them and how much, if any, of the gas reached the atmosphere.

Indeed, a whole line of research, based on a seminal study published in 1998, suggested that not only is human willpower a depletable resource, but it's also drawn from a singular source in the brain. Many psychologists now think this phenomenon, dubbed "ego depletion," doesn't exist at all.

(image) The comet that Europe's Rosetta spacecraft orbited for more than two years was probably born in the realm of icy bodies beyond Neptune, a new study suggests. New analyses of the orbit of Comet 67P/Churyumov-Gerasimenko — on which Rosetta intentionally crash-landed on Sept. 30, ending the probe's historic mission — trace the object's origins back to the Kuiper Belt, whose most famous denizen is Pluto. "These results come from computations of the comet's orbit from the present to the past, which is computationally difficult due to the chaosity of the orbit caused by close encounters with Jupiter," Mattia Galiazzo, a postdoctoral fellow in the Department of Physics and Astronomy at Western University in Ontario, Canada, said in a statement.

(image) For more than 15 years, a lone scientist in southern Finland has spent countless winter nights among the snowy fields and frozen lakes around his village, in pursuit of one of the most ephemeral mysteries of the heavens: the faint, almost phantasmagorical sounds heard during intense displays of the aurora borealis, or northern lights. The epic study by acoustician Unto K. Laine includes the first audio recordings of the muffled crackling or popping sometimes heard overhead during spectacular aurora displays. Over the years, the sounds of the northern lights have been explained as illusions, imagination, inebriation or even voices from the spiritual world.
Fri, 14 Oct 2016 10:05:36 -0400By Kate Kelland LONDON, (Reuters) - Scientists launched a global initiative on Friday to map out and describe every cell in the human body in a vast atlas that could transform researchers' understanding of human development and disease. The atlas, which is likely to take more than a decade to complete, aims to chart the types and properties of all human cells across all tissues and organs and build a reference map of the healthy human body, the scientists said. Cells are fundamental to understanding the biology of all health and disease, but scientists cannot yet say how many we have, how many different types there are, or how they differ from one organ to another, one project leader said.

(image) More than a trillion galaxies are lurking in the depths of space, a new census of galaxies in the observable universe has found — 10 times more galaxies than were previously thought to exist. An international team of astronomers used deep-space images and other data from the Hubble Space Telescope to create a 3D map of the known universe, which contains about 100 to 200 billion galaxies. In particular, they relied on Hubble's Deep Field images, which revealed the most distant galaxies ever seen with a telescope.

Sadly, such warnings come only after the damage is done, when enough clear reports of adverse reactions begin to emerge. Now, scientists at Columbia University in New York have harnessed the power of data science to identify two common prescription drugs that, if mixed, can have deadly consequences.
