Although the white coats that doctors wear have been scrutinized for their authoritarian look, the open-in-the-back gowns that hospital patients wear, and the effect these gowns have on patients' dignity and state-of-mind while in the hospital, have gone largely unexamined. "There are a number of ways in which the hospital system traumatizes patients, and one of those is that we take away the patients' clothes and put them in a somewhat depersonalizing, unisex blue gown, when that's not completely necessary," Dr. Todd Lee, an assistant professor of Medicine at McGill University in Montreal, told Live Science.

A new military-sponsored program aims to develop a tiny device that can be implanted in the body, where it will use electrical impulses to monitor the body's organs, healing these crucial parts when they become infected or injured. Known as Electrical Prescriptions, or ElectRx, the program could reduce dependence on pharmaceutical drugs and offer a new way to treat illnesses, according to the Defense Advanced Research Projects Agency (DARPA), the branch of the U.S. "The technology DARPA plans to develop through the ElectRx program could fundamentally change the manner in which doctors diagnose, monitor and treat injury and illness," Doug Weber, program manager for DARPA's biological technologies office, said in a statement. The implant that DARPA hopes to develop is something akin to a tiny, intelligent pacemaker, Weber said.

NASA's newest Mars spacecraft is safely in orbit around the Red Planet, and the probe's handlers couldn't be happier. The MAVEN spacecraft arrived at Mars late Sunday (Sept. 21) after a picture-perfect orbital insertion burn that slowed the probe down enough to be captured by the Red Planet's gravity in a feat that had mission team members cheering with excitement and relief. "Wow! What a night," MAVEN project manager David Mitchell, of NASA's Goddard Space Flight Center in Greenbelt, Maryland, said Sunday during a press briefing after the probe reached the Red Planet. "You get one shot with Mars orbit insertion, and MAVEN nailed it tonight." [See images from the MAVEN mission]

A particle detector floating 250 miles (400 kilometers) above Earth has analyzed 41 billion cosmic-ray particles, and the data have revealed new insights into the mysterious and invisible dark matter that physicists believe makes up 27 percent of the universe. The Alpha Magnetic Spectrometer (AMS) detector aboard the International Space Station already gathered evidence of dark matter last year, but the new results are the most precise measurements of cosmic-ray particles yet. They include 50 percent more data, and have revealed new insights into the origin of the particles found in cosmic rays, Samuel Ting, a professor of physics at MIT and an AMS spokesman, said during a live webcast at the CERN (the European Organization for Nuclear Research) lab in Switzerland yesterday (Sept. 18). Physicists theorized the existence of invisible, and so far undetectable, dark matter as a way to explain why galaxies and celestial bodies don't just unravel and fly apart.

The brilliant minds behind research studies about how Earth's magnetic field affects pooping dogs and why people see Jesus in toast were honored tonight (Sept. 18) during one of the most purposefully ridiculous ceremonies in all of science: the Ig Nobel Prizes. Each year, the Ig Nobel Prizes (a parody of the somewhat more famous Nobel Prizes) are awarded to scientists whose research "makes people laugh and then think." Improbable Research, the organization that awards the prizes, runs the annual ceremony here at Harvard University's Sanders Theater. "The achievements speak for themselves all too eloquently," Master of Ceremonies Marc Abrahams said during tonight's Ig Nobel presentations. For example, this year's prize in Arctic science went to a group of researchers who dressed up like polar bears to see how reindeer in Norway would react compared with their reactions to humans.

You can see for yourself on Thursday (Sept. 18) at the 24th annual Ig Nobel Prize Ceremony, an event that honors the hilarious (and sometimes ridiculous) side of scientific research and discovery. Much like its slightly more famous counterpart, the Nobel Prize, the Ig Nobel Prize is bestowed upon those who have recently made significant contributions in such fields as chemistry, physics and biology. "The Ig Nobel Prizes honor achievements that first make people laugh, and then make them think," according to a statement from Improbable Research, the organization behind the award ceremony. Ten Ig Nobels are awarded each year at Harvard's Sanders Theater in Cambridge, Massachusetts, and this year's ceremony will be webcast live on Live Science.

In the 1998 movie "Armageddon," an asteroid the size of Texas threatens to collide with Earth in 18 days. To save the planet from destruction, a ragtag team of deep-sea oil drillers volunteers to divert the massive space rock by burying a nuclear bomb beneath its surface and blasting it into two pieces that will fly past Earth. But despite its entertainment value, the film is fantastically inaccurate, said astronomer Phil Plait, who writes the "Bad Astronomy" blog on Slate.com. During his talk, Plait showed a clip from "Armageddon" in which Bruce Willis' character struggles to detonate the bomb, by hand, before the asteroid smacks into Earth and destroys all life.

Sharks exposed to ocean water acidified by too much carbon dioxide alter their behavior, swimming in longer spurts than sharks in typical ocean water, particularly during their nighttime wanderings. The new findings, published today (Sept. 16) in the journal Biology Letters, are troubling, given that one effect of the human consumption of fossil fuels is to make ocean water more acidic. "Usually when you expose a fish to some kind of environmental stressor, they usually acclimate to that stressor, and that makes them less vulnerable to that stressor," said study researcher Fredrik Jutfelt, an animal physiologist at the University of Gothenburg in Sweden. "But here, it seemed like this high CO2 [carbon dioxide] continued to be a stressor to these sharks for quite a long time." [On the Brink: A Gallery of Wild Sharks (Photos)]

One of Saturn's iconic rings looks much different today than it did just a few decades ago, and scientists aren't sure why. NASA's twin Voyager spacecraft spotted many bright clumps in Saturn's F ring when they flew by the gas giant in the early 1980s. "Saturn's F ring looks fundamentally different from the time of Voyager to the Cassini era," study lead author Robert French, of the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California, said in a statement. French and his team have a hypothesis that could explain what's going on, and it's tied to the number of Saturn "moonlets" found near the F ring over the decades.

Air Force and NASA have ironed out problems that prevented scientists from obtaining a steady stream of military tracking data on meteor explosions within Earth's atmosphere. Meteor detonations within Earth's atmosphere can be seen by U.S. Using this government data, in early 2013, NASA's Jet Propulsion Laboratory (JPL) launched a new website to share the details of meteor explosion events. Due to budget cuts and personnel reductions, NASA's military partner was no longer able to carry out the work.

NASA is staunchly defending the science plans for its flagship Mars rover Curiosity in the wake of a recent senior-level review that at times harshly criticized the mission's science operations. Curiosity had been driving toward the mountain since it landed on Mars in 2012. NASA officials lauded the success so far of Curiosity's $2.5 billion mission. Jim Green, NASA's director of planetary science, was quick to point out Curiosity's early success, citing the rover's discovery that Mars was once a habitable world in the ancient past — a key mission goal.

By Kate Kelland LONDON (Reuters) - British and Japanese scientists have managed to "reset" human stem cells to their earliest state, opening up a new realm of research into the start of human development and potentially life-saving regenerative medicines. In work described by one independent expert as "a major step forward", the scientists said they had successfully rebooted pluripotent stem cells so they were equivalent to those of a 7 to 10-day old embryo, before it implants in the womb. By studying the reset cells, they said they hoped they would now be able to learn more about embryo development, and how it can go wrong and cause miscarriage and developmental disorders. "These cells may represent the real starting point for formation of tissues in the human embryo," said Austin Smith, director of the Britain's Cambridge Stem Cell Institute, who co-led the research published in the journal Cell on Thursday.

By Will Dunham WASHINGTON (Reuters) - Gibbons - the small, long-armed tree swingers that inhabit the dense tropical forests of Southeast Asia - have become the last of the planet's apes to have their genetic secrets revealed. "We now have whole genome sequences for all the great apes and, with this work, also the small apes - gibbons," said Jeffrey Rogers, a primate genetics researcher at the Human Genome Sequencing Center at Baylor College of Medicine in Houston. "This provides new information and insight into the history of the human genome, in evolutionary terms," added Rogers, who participated in the study published in the journal Nature. Among the great apes, the chimpanzee genome was published in 2005, followed by the orangutan in 2011 and the gorilla and the bonobo in 2012.

Instead, the microorganism is somehow able to recognize the brains of different ant species, and releases its mind-controlling chemical cocktail only when in its preferred host, new research shows. "Behavioral manipulation is such a complex [characteristic] that it only occurs when there's a very close coevolution between pathogen and host," said Charissa de Bekker, a molecular biologist at Pennsylvania State University and lead author of the new study, published in August in the journal BMC Evolutionary Biology. "The theory is that every species of ant has its own species of fungi that it gets infected by," de Bekker told Live Science.

A new ultra-precise particle detector is being developed to investigate the bizarre properties and behaviors of tiny elementary particles that seem to defy the laws of traditional physics. Department of Energy recently awarded $1.2 million to a team of physicists from Indiana University's Center for Exploration of Energy and Matter to build the new particle detector. The Standard Model is thought to be the golden rule of particle physics. In particular, physicists think the Belle II detector could reveal more about the uneven distribution of matter and antimatter in the universe.

It's not every day that an ordinary fishing trip turns into an encounter with an oversized alien-like sea creature, but that's what happened recently to one Florida fisherman. Steve Bargeron was fishing off a dock in Fort Pierce, Florida, last week when a couple fishing nearby pulled up what Bargeron jokingly described as an "alien creature." The couple wasn't interested in keeping the strange, lobster-like animal, which was flopping its tail wildly, Bargeron told Live Science. But Bargeron's close encounter with this strange-looking specimen isn't really that strange after all, according to Roy Caldwell, a professor of integrative biology at the University of California, Berkeley. Caldwell said he saw the photos online and instantly recognized the creature as a mantis shrimp, or stomatopod, a marine crustacean commonly found in the waters off Florida.
