Heart rules the head when we make financial decisions

Our 'gut feelings' influence our decisions, overriding 'rational' thought, when we are faced with financial offers that we deem to be unfair, according to a new study. Even when we are set to benefit, our physical response can make us more likely to reject a financial proposition we consider to be...

Pancreatic cancer may be detected with simple intestinal probe

By simply shining a tiny light within the small intestine, close to that organ’s junction with the pancreas, physicians have been able to detect pancreatic cancer 100 percent of the time in a small study. The light, attached to a probe, measures changes in cells and blood vessels in the small intestine produced by a growing cancer in the adjoining...

Activating genes that suppress tumors and inhibit cancer

A promising new strategy for "reactivating" genes that cause cancer tumors to shrink and die has now been developed. The discovery may aid the development of an innovative anti-cancer drug that effectively targets unhealthy, cancerous tissue without damaging healthy, non-cancerous tissue and vital...

Method to strengthen proteins with polymers

Scientists have synthesized polymers to attach to proteins in order to stabilize them during shipping, storage and other activities. The study findings suggest that these polymers could be useful in stabilizing protein formulations.

New discoveries about severe malaria

Researchers have uncovered new knowledge related to host-parasite interaction in severe malaria, concerning how malaria parasites are able to bind to cells in the brain and cause cerebral malaria -- the most lethal form of the disease.

Surgical removal of abdominal fat reduces skin cancer in mice

In animal studies, Rutgers scientists have found that surgical removal of abdominal fat from mice fed a high-fat diet reduces the risk of ultraviolet-light induced skin cancer – the most prevalent cancer in the United States with more than two million new cases each year – by up to 80...

Physical properties predict stem cell outcome

Tissue engineers can use mesenchymal stem cells derived from fat to make cartilage, bone, or more fat. The best cells to use are ones that are already likely to become the desired tissue. Researchers have discovered that the mechanical properties of the stem cells can foretell what they will become, leading to a potential method of concentrating them for use in...

Hunter-gatherers and horticulturalist lifestyle linked to lower blood pressure increases, atherosclerosis risks

Traditional "hunter-gatherer" and "horticulturalist" populations have significantly lower age-related increases in blood pressure and less risks of atherosclerosis than "modernized" populations. Lifestyle factors of these traditional populations -- high physical activity and high fruit and vegetable diets -- may protect against normal aging phenomena, high blood pressure and hardening of the...

Proven friction stir welding technology brings together reliability and affordability for NASA's space launch system

NASA's next heavy-lift launch vehicle, the Space Launch System, is moving further in development faster thanks to proven advanced technologies like friction stir welding. Friction stir welding uses frictional heating combined with forging pressure to produce high-strength bonds virtually free of defects. The welding process transforms metals from a solid state into a "plastic-like" state, and uses...

Stunning view of Lyrids and Earth at night

On the night of April 21, the 2012 Lyrid meteor shower peaked in the skies over Earth. While NASA allsky cameras were looking up at the night skies, astronaut Don Pettit aboard the International Space Station trained his camera on Earth. Video footage from that night is now revealing breathtaking images of Earth with meteors ablating -- or burning up -- in the...

Hubble spies edge-on beauty: Galaxy NGC 891

Visible in the constellation of Andromeda, NGC 891 is located approximately 30 million light-years away from Earth. The NASA/ESA Hubble Space Telescope turned its powerful wide field Advanced Camera for Surveys towards this spiral galaxy and took this close-up of its northern...

Cassini spots tiny moon, begins to tilt orbit

NASA's Cassini spacecraft made its closest approach to Saturn's tiny moon Methone as part of a trajectory that will take it on a close flyby of another of Saturn's moons, Titan. The Titan flyby will put the spacecraft in an orbit around Saturn that is inclined, or tilted, relative to the plane of the planet's equator. The flyby of Methone took place on May 20 at a distance of about 1,200 miles...
