Kayan Loris, A Newly Discovered Species of Slow Loris

kayan-slow-loris-primate

The primate genus Nycticebus contains a group called slow lorises, which is closely related to lemurs, and can be found across South East Asia. Recently, biologists discovered a new species in the jungles of Borneo. The scientists published their findings in the American Journal of Primatology. The animals are omnivores, eating insects, small birds, reptiles, […]

First Detection of Radio-Emitting Jets from a Stellar-Mass Black Hole Outside Our Galaxy

first detection of radio-emitting jets from a stellar-mass black hole outside our own galaxy

A newly published study reveals the first detection of radio-emitting jets moving at more than 85 percent the speed of light from a stellar-mass black hole outside our own galaxy. Back in January, a new X-ray source flared and rapidly brightened in the Andromeda galaxy (M31), located 2.5 million light-years away. Classified as an ultraluminous […]

Foam Injections Could Prevent Deaths on the Battlefield

foam-based product slows blood loss

Future combat medics could save the lives of soldiers, preventing them from bleeding out on battlefields, by injecting medical foam into their bodies. The scientists presented their findings at the 2012 Annual Meeting of the American Association for the Surgery of Trauma in Kauai, Hawaii. Currently, little that can be done to stanch internal bleeding […]

Study Suggests Life on Land Began 65 Million Years Earlier than Current Estimate

dickinsonia-parvancorina-terrestrial

A new study shows that fossils that have been regarded as ancient sea creatures may have actually been land-dwelling lichen, suggesting life on land began 65 million years earlier than current estimates. The scientists published their findings in the journal Nature. However, other paleontologists flatly reject the hypothesis made by Gregory Retallack, a geologist from […]

Kitchen Utensils Can Transfer Viruses

knife-cutting-produce

According to a new study, cutting unclean fruits and vegetables can spread viruses to the knife. Scienitists already knew that bacteria could contaminate utensils this way, but this is the first study to see if the hepatitis A virus and norovirus can be transmitted this way. The scientists published their findings in the journal Food […]

Geneticists Grow Fish with Limbs to Duplicate Evolutionary Pressure

zebrafish-limbs

The fossil record gives clues about how limbs grew from fish fins in a series of stages, but scientists are still trying to fill in the details and determine what genetic changes might have allowed limbs to grow. The scientists published their findings in the journal Developmental Cell. In order to do so, scientists have […]

4.5 km Asteroid Tumbles Past Earth

NASA’s Goldstone radar is capturing new images of the 4.5 km asteroid Toutatis as it passes by Earth this month. This week, NASA’s Goldstone radar is tracking a large asteroid as it passes by Earth, and obtaining unusually clear images of the tumbling space rock. “There is no danger of a collision with Earth,” says […]

“Silicon Nanophotonics” Integrates Optical Components with Electrical Circuits

cross-section-nanophotonic-silicon-chip

IBM announced an advance in the ability to use light instead of electrical signals for information transmission in future computing applications. “Silicon nanophotonics” allows the integration of different optical components side-by-side with electrical circuits on a single silicon chip, using sub-100nm semiconductor technology. Dr. Solomon Assefa will present details at the IEEE International Electron Devices […]

X-rays Reveal Potential Drug Target for Ulcer-Causing Bacteria

potential drug target in ulcer-causing bacteria

Using X-rays from SLAC’s Stanford Synchrotron Radiation Lightsource, scientists have deciphered the three-dimensional molecular structure of a very promising drug target in H. pylori, the ulcer-causing bacteria that infect half the world’s population. In 1982, Australian scientists extracted bacteria from a person’s stomach, grew them in a petri dish and identified them as the cause […]

Neolithic Pottery Reveals Cheese-Making from 7,500 Years Ago

feta-cheese

A team of scientists from Princeton University and the University of Bristol, UK, have discovered traces of dairy fat in ancient ceramic fragments, indicating that humans have been making cheese in Europe for up to 7,500 years. Early dairy farmers probably devised cheese-making as a way to preserve milk. The scientists published their findings in […]

Samarium Hexoboride Behaves Like a Topological Insulator

samarium-hexoboride

Samarium hexoboride, a compound that had been poorly understood and that can gain conducting properties at very low temperatures, may be a topological insulator in its bulk form, conducting electricity on its surface while the rest of the material behaves like an insulator. The scientists published their findings in three papers in preprints on arXiv […]

Hubble Reveals Seven Faraway Galaxies

The Hubble Ultra Deep Field 2012 campaign revealed seven previously unseen populations of faraway galaxies, viewing them as they looked 350 to 600 million years after the big bang, more than 13 billion years ago. Washington — Using NASA’s Hubble Space Telescope, astronomers have uncovered a previously unseen population of seven primitive galaxies that formed […]
