Embryonic stem cells accrue genetic changes

...dishes. Whether the changes affect the stem cells' abilities to become other cell types is also unknown. Although research with human embryonic stem cells is still in the lab -- not the clinic -- focusing on what the cells can do and how they are controlled, the hope is that in the future these cells might h...

Researchers use brain scans to predict behavior

... Sapir noted that the reward systems' predictive abilities may be damaged or missing in some patients with mental illness, causing these patients to perceive the world as alien and unpredictable. Other areas involved in prediction included regions in the visual cortex involved in the analysis of the motion...

A radical solution for environmental pollution

... like to transfer T. aromatica's toluene-degrading abilities to other bacteria that are more easily cultured and more tolerant of various environmental conditions. He'd also like to coax T. aromatica into neutralizing other kinds of pollutants, but the first step is understanding exactly how the bug breaks dow...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...d with strands of DNA can create tiny sensors with abilities to detect odors and tastes, according to researchers at the University of Pennsylvania and Monell Chemical Sciences Center. Their findings are published in the current issue of the journal Nano Letters, a publication of the American Chemical Society....

Lance Armstrong through a physiological lens: hard training boosts muscle power 8%

...with a strong genetic makeup, but he maximized his abilities and got where his is through dedication and hard training." Source The study, entitled "Improved muscular efficiency displayed as 'Tour de France' champion matures," appears in the June issue of the Journal of Applied Physiology, published by the A...

Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals

...ave found clues to suggest that birds' orientation abilities may be more complex than previously thought and that birds may be able to interpret magnetic signals by more than one mechanism. The work is reported in Current Biology by a team including Thorsten Ritz, of the University of California, Irvine, and W...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

... to those of a smoking human mother. The breathing abilities and lung development of these monkeys was then compared with monkeys born to mothers who had received both nicotine and vitamin C doses during pregnancy. A third group of baby monkeys that did not receive either nicotine or vitamin C during prenatal ...

Bad aftertaste? New sensory on/off switch may 'cure' bane of artificial sweetener search

...ogy researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change. The new supermolecules have more units that wil...

Virginia Tech group adds tools to DNA-targeted anti-cancer drugs

...ogy researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change. The new supermolecules have more units that wil...

15 generations of untrained jocks, couch potatoes show big physiological adaptations

...hat prompt the initial signal for the differential abilities to run on a treadmill without training, as well as the mechanisms responsible for the "natural" improvements in muscular, cardiovascular and pulmonary oxygen delivery. Further in the future the physiologists hope that identifying these genes and und...

Scientists find viruses can't stick to sea bugs in the dark

..., which can seriously affect their life-sustaining abilities but mow a researcher at the University of Warwick has discovered that these viruses don't work in the dark, according to research presented today (Monday, 04 April 2005) at the Society for General Microbiology's 156th Meeting at Heriot-Watt Universit...

An (ecological) origin of species for tropical reef fish

...s barrier. Since all of these species have similar abilities to disperse, I expected to find genetic differences that corresponded to the barrier in all of them, but, surprisingly, that wasn't the case." Mitochondrial DNA of adult fish and larvae from three locations in the Caribbean and from three locations ...

Rhesus monkeys can assess the visual perspective of others when competing for food

...tition-like situations may bring out the primates' abilities more than experiments that don't involve competiti...otentially push back the time during which our own abilities to "read the minds of others" must have evolved. Moreover, they suggest strongly a reason why these ...

Migratory songbirds have a specialized night-vision brain area

...may be responsible for the impressive navigational abilities of birds migrating during the night. In future studies, Jarvis, Mouritsen and their colleagues plan to test this hypothesis in more detail, they said. ...

Turning viruses into allies against cancer

...g re-programmed to take advantage of their natural abilities to infiltrate, commandeer, replicate and destroy, but only in tumor cells and not surrounding healthy tissue. Several of these "oncolytic" (cancer-killing) viruses are in varying stages of development, including modifications of the virus that cause...

Elephants imitate sounds as a form of social communication

...s that elephants may be using their vocal learning abilities in a similar manner, and opens a fascinating new area for research on how elephants use vocal learning." Vocal learning is important because it enables an open communication system in which animals and humans develop new signals with shared associat...
