Carnegie Mellon develops non-invasive technique to detect transplant rejection at cellular level

...etime of immunosuppressive therapy and the risk of losing the new organ due to rejection. Physicians typically monitor patients for organ rejection following a heart transplant by performing frequent heart biopsies for the first year. Heart biopsies are invasive procedures that involve threading a catheter ...

Study: Competition for sex is a 'jungle out there'

...ersity of Pittsburgh. "The concern is that we are losing habitat really rapidly globally, especially in tropical areas, and losing pollinators there as well," Knight said. "We show that these areas are sensitive to pollen limitati...

Less is more, gene study shows

...te evidence for the "less is more hypothesis" that losing certain genes offered tangible benefits, Zhang sai... the researchers next wanted to figure out whether losing the genes benefited humans in any way. Studies on mice suggested that loss of a gene called MBL1---w...

Watching the brain switch off 'self'

...w, researchers have caught the brain in the act of losing "self" as it shuts down introspection during a demanding sensory task. The researchers--led by Rafael Malach and Ilan Goldberg of the Weizmann Institute of Science reporting in the April 20, 2006, issue of Neuron--say their findings show that self-...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...pped immediately. Their numbers are so small that losing one or two rhinos to a poacher could upset the remaining rhinos' chances of survival," said Sybille Klenzendorf, lead biologist of WWF's Species Conservation Program. "Conservationists and Sabah government agencies are hopeful that there is a chance...

Mice lacking social memory molecule take bullying in stride

...ice and men, social status is important; for mice, losing to a dominant mouse usually means that they avoid the dominant and they avoid social situations," explained NIMH director Dr. Thomas Insel. "These new findings add to a growing literature on the molecular basis of social behavior, helping us to know...

Oops! Researchers publish new findings on the brain's response to costly mistakes

... an error that carries consequences ?for instance, losing money. By contrast, the same area of the brain doesn't show the same level of activity when the mistake doesn't carry a penalty, or even when a correct action carries a reward. The rACC is thought to be involved with emotional responses, and scient...

Report shows deforestation threatens Brazil's Pantanal

...d, with some districts in the Paraguay River Basin losing more than 90 percent of their vegetation. "It is extremely important to conserve the areas surrounding the Pantanal lowlands, because they are the headwaters of the rivers that make up the Pantanal," said Sandro Menezes, manager of CI-Brazil's Panta...

Poison dart frog mimics gain when birds learn to stay away

... can look like the less toxic poison frogs without losing any protection from predators. The result is surprising, because mimicry theory predicts that when all three frogs occur in the same forest, the mimics would look like the more toxic frog species, the more abundant of the toxic frogs, or look like b...

'Dead zone' summer killed billions of ocean state mussels

...welling bacteria. "When we lose mussels, we may be losing the ability to prevent future dead zones from forming," Altieri said. "So these sorts of extinctions may trigger a downward spiral, with coastal zones less able to handle environmental degradation." According to a 2004 United Nations Environment Pro...

Thinner and younger

...lammation than lean people, so it makes sense that losing weight might increase average lifespan by lowering the risks of some age-related diseases, such as diabetes and atherosclerosis. But in animal studies not only did more of the animals live longer, the maximum length of a rat's or mouse's life also in...

Carnegie Mellon researchers discover new cell properties

... exhibit similar problems to the HGPS nuclei, like losing their round shape and perkiness. "Our NIH collaborators have also found that the normal aged nuclei show the same structural changes as HGPS," Dahl said. ...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...making a change. First, if you're overweight, then losing some pounds will reduce or even eliminate the amount of heartburn you suffer. Second, raising the head of your bed will cut down on the amount of stomach acid that can enter your esophagus while you sleep. But Gerson noted a conundrum in her counsel...

One-third of adults with diabetes still don't know they have it

How plants avoid feeling the burn

...rots and Vitamin A -- become oxidized, or charged, losing an electron in the process. Now, Fisher and other ASU scientists have found a way to measure for the first time the electrical conductance within such an important biomolecule. And in doing so, the team has produced a new discovery which shatters ...

How ancient whales lost their legs, got sleek and conquered the oceans

... recognize today during the next 15 million years, losing their hind limbs in a dramatic example of evolutionary change. "We can see from fossils that whales clearly lived on land - they actually share a common ancestor with hippos, camels and deer," said team member Martin Cohn, Ph.D., a developmental bio...

Pollution threatens coral health by preventing lesions from healing, UCF study shows

...rge in the same manner that sea walls do. "We're losing places where animals can hide and fish can feed," Fauth said. "And reefs where people dive are being degraded." Tissue samples from mustard hill coral were taken from eight Broward County sites, including near-shore and offshore locations at each o...

Beekeepers work hard for the honey, despite changing tupelo forest

Looking ahead, Eisen is continuing to explore the genomes of other animal-bacterial symbioses to understand how such systems originate and work.
