Unique Drug Combinations Show Positive Results in Fighting Late-Stage Melanoma

Using novel high-throughput screening techniques to overcome the problems of resistance and partial response to single-drug cancer therapy in patients with melanoma, Yale scientists identified several unique drug therapy combinations that show positive results in fighting late-stage melanoma. Yale Cancer Center researchers have identified several effective combinations of therapies that inhibit melanomas driven by two […]

Fast DNA Origami Allows Molecules to be Folded in Minutes

dna-origami-artificial

A new study indicates that DNA strands can be coaxed to fold into shapes in a matter of minutes. This could speed up progress in the field of DNA origami. The scientists published their findings in the journal Science. So far, biotechnologists have only been able to make simple forms out of DNA, like tubes, […]

NASA Probes Ebb & Flow Set for Mission-Ending Moon Impact

NASA’s GRAIL mission spacecraft, Ebb and Flow, are set to impact the moon near a crater named Goldschmidt on December 17th, hitting the surface at 3,760 mph and ending their successful endeavor to map the moon’s gravity. Pasadena, California — Twin lunar-orbiting NASA spacecraft that have allowed scientists to learn more about the internal structure […]

The failure of the US National Ignition Facility’s six-year campaign to demonstrate fusion in the lab has the government deciding on a more methodical path for harnessing the most powerful laser ever built. The government’s new plan [PDF] was revealed to Nature, and it calls for a slower, more deliberate approach to achieve ignition, the […]

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 […]

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 […]

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 […]

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 […]
