Facial attraction -- choice of sexual partner shaped the human face
...upper face similar in height to a female face, but much
broader. These differences can be found throughout human history. As a result, a simple ratio of measures could be used to calculate facial attractiveness in a biological and mathematical way. Dr Eleanor Weston, palaeontologist at the Natural Histo...

of the Guayana Shield region of the northern Amazon that is the largest intact tract of tropical forest on Earth. In addition, portions of other large non-HFLD countries are in the same situation. For example, although Brazil has four other major eco...

...ue-specific manner than previously appreciated and much
of this additional regulation occurs in the nervous system. The alternative splicing step allows a single gene to specify multiple protein products by processing the RNA transcripts made from genes (which are translated to make protein). We are ...
Pollution causes 40 percent of deaths worldwide, study finds
...deaths each year but also makes millions of people much
more susceptible to such killers as acute respiratory infections, malaria and a host of other life-threatening diseases, according to the research. Among the study's other main points: Nearly half the world's people are crowded into urban areas, ...

Features of replication suggest viruses have common themes, vulnerabilities

like antibiotics are used to attack different kinds of bacterial pathogens. "It turns out that viruses previously thought of as distinct share common features," says Paul Ahlquist, an HHMI investigator and virologist at UW-Madison. "We've found som...

Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless
... the glutathione S-transferase (GST) family, by as much
as 80 percent in some participants. GST enzymes are believed to be crucial to the bodys defense against cancer-causing chemicals and other toxins, according to the studys lead investigator, H.-H. Sherry Chow, Ph.D., a research associate professor a...
High blood pressure, low energy -- a recipe for heart failure
... alpha sits in the nucleus of cells and senses how much
energy is needed. When a heart cell finds itself short on energy, say because it's being called on to contract harder or faster, its ERR is activated by an inducible co-activator called PGC-1, turning on genes that increase the heart's capacity to bu...

oxygen can be delivered to the extremities. We were surprised to find that the effect is most pronounced in the orifices leading to the legs, where more and more of the space is taken up by tracheal tubes in larger species, said Alex Kaiser, biolog...
Abnormal fat metabolism underlies heart problems in diabetic patients

of this enzyme in their hearts developed defects in mitochondrial function which became worse when they were fasted a condition that, like diabetes, causes the heart to use lipids for fuel. A 16-hour fast caused significant problems with the mouse h...

more accurate than the normal statistical analysis of such dynamic systems such as crowds or plasmas and it should be particularly good at picking up the phase transitions from disorder to order in such complicated systems. Initially the resear...
