Schools must track academic progress of homeless students, researchers argue

Schools must track the academic progress of homeless students with as much care as they track special education, Title I and English language learner students, according to researchers at University of the Pacific. And funds earmarked to help homeless youth should buy more than backpacks and bus tokens.

Investigational personalized cellular therapy tolerated well by patients

Genetically modified versions of patients’ own immune cells successfully traveled to tumors they were designed to attack in an early-stage trial for mesothelioma and pancreatic and ovarian cancers at the Perelman School of Medicine at the University of Pennsylvania. The data adds to a growing body of research showing the promise of CAR T cell technology. The interim results will be presented at the American Association for Cancer Research Annual Meeting 2015, April 18-22.

Animal study shows why long-time consumption of soyfoods reduces breast cancer recurrence

Women diagnosed with breast cancer are often told not to eat soyfoods or soy-based supplements because they can interfere with anti-estrogen treatment. But new research could eventually impact that advice, because in animals, a long history of eating soyfoods boosts the immune response against breast tumors, reducing cancer recurrence.

The Milky Way Over Loon Island: A Stargazer’s Stunning View (Photo)

The Milky Way Over Loon Island: A Stargazer's Stunning View (Photo)This stunning panoramic of the Milky Way shows our host galaxy arching over Lake Sunapee. Astrophotographer A. Garrett Evans took the image Loon Island Lighthouse on Lake Sunapee in Sunapee, New Hampshire on Feb. 28, 2015. Our host galaxy, the Milky Way, is a barred spiral galaxy seen as a band of light in the night sky. Evans found the weather co-operative the night he took the image.

Evidence of Pre-Columbus Trade Found in Alaska House

Evidence of Pre-Columbus Trade Found in Alaska HouseBronze artifacts discovered in a 1,000-year-old house in Alaska suggest trade was occurring between East Asia and the New World centuries before the voyages of Columbus. Archaeologists found the artifacts at the "Rising Whale" site at Cape Espenberg. "When you're looking at the site from a little ways away, it looks like a bowhead [whale] coming to the surface," said Owen Mason, a research associate at the University of Colorado, who is part of a team excavating the site. The new discoveries, combined with other finds made over the past 100 years, suggest trade items and ideas were reaching Alaska from East Asian civilizations well before Christopher Columbus arrived in the Caribbean Sea in 1492 archaeologists said.

Man Goes Exploring with Metal Detector, Finds Roman-Era Grave

Man Goes Exploring with Metal Detector, Finds Roman-Era GraveA man in England went exploring with a metal detector and made the discovery of a lifetime: an exquisitely preserved Roman-era grave filled with artifacts, including bronze jugs, mosaic glassware, coins and hobnails from a pair of shoes, all dating to about A.D. 200. The grave likely belonged to a wealthy individual, said Keith Fitzpatrick-Matthews, the archaeology and outreach officer for the North Hertfordshire District Council. Once Fitzpatrick-Matthews and his colleagues located the grave, they also found evidence of a nearby building, likely a shrine or temple, attached to a villa. The man with the metal detector, Phil Kirk, found the grave in a field in Kelshall, a small village located between London and Cambridge.

Scientists: 3 wolves remain at Isle Royale National Park

This photo released by Michigan Technological University taken on Feb. 15, 2015, shows the last three wolves known to live at Isle Royale National Park in Lake Superior. Their numbers have dropped steadily in recent years, and scientists are calling for more wolves to be brought to the wilderness island to keep the moose population in check. (Rolf Peterson/Michigan Technological University via AP)TRAVERSE CITY, Mich. (AP) — The gray wolves of Isle Royale National Park, which scientists have studied closely for more than half a century along with the moose on which they feed, are on the verge of disappearing as the most recent census showed that only three remain, scientists said Friday.

Scientists create self-powering camera

By Elly Park New York, NEW YORK – Scientists at Columbia University in New York have successfully built a camera that is capable of producing images using power harvested from the surrounding incident light.  The prototype self-powering camera takes an image each second, and in a well-lit scene it can operate indefinitely. The team is led by Shree Nayar, Professor of Computer Science at Columbia Engineering,  “What we have designed here is an image sensor with pixels, with this new design that can not only capture pictures but also generate power from the pixels, in order to capture the images themselves. In modern cameras photo diodes, tiny devices inside each pixels of the image sensor, measure the amount of light that falls onto it, and Nayar said he noticed that the process is similar to photo diodes used inside solar panels to harvest energy.   “It turns out exactly the photo diode is also used in solar cells which are used in solar panels to harvest energy from light, except that they are being used in a slightly different circuit.

U.S. eyes new ways to prepare and win future war in space

By Andrea Shalal COLORADO SPRINGS, Colo. (Reuters) – The United States needs disruptive new technologies, new ways of acquiring equipment and bandwidth, and closer ties with global allies to stay ahead of growing challenges in space from China, Russia and others, the head of U.S. Air Force Space Command told Reuters. General John Hyten said the United States had been bracing for threats to its satellite systems for years, but continued anti-satellite testing by potential foes had fueled a fresh sense of urgency in both industry and government about the need to prepare to win a possible war in space.

Amazonian tribe study shows how human bodily bacteria is changing

Handout picture of a group of huts in an isolated village inhabited by Yanomami Amerindians in southern VenezuelaBy Will Dunham WASHINGTON (Reuters) – Everyone's body is brimming with bacteria, and these microbes do plenty of good things like building the immune system and helping digestion. A study published on Friday looking at the gut, mouth and skin microbes in people from a small, isolated tribe in southern Venezuela's Amazonian jungles shows just how much modern life may be altering humankind's bodily bacteria. The Yanomami villagers, secluded from the outside world until 2009, possessed the most diverse collection of bacteria ever found in people including some never before detected in humans, said scientists whose research appears in the journal Science Advances. The researchers were surprised to learn the Yanomami's microbes harbored antibiotic-resistant genes including those conferring resistance to manmade antibiotics, considering they never had exposure to commercial antibiotics.

NASA electric rover goes for a spin

Tourists take pictures of a NASA sign at the Kennedy Space Center visitors complex in Cape Canaveral, FloridaBy Jim Drury Texas, Houston, U.S. – Driving NASA's Modular Robotic Vehicle (MRV) looks out of this world – and the leading space agency say this might one day be a possibility. Developed at NASA's Johnson Space Center in Houston, Texas it's a fully electric vehicle which the agency say is well-suited for busy urban environments. Turns of the steering wheel are recorded by sensors and sent to computers at the vehicle's rear where they are interpreted immediately, instructing motors in one or all of its four wheels to turn as commanded. A force feedback system in the steering wheel means the driver will feel the same resistance and sensations as a car.
