Male births are more likely to reduce quality of life and increase severe post-natal depression
Women who give birth to boys are more likely to suffer from post-natal depression and reduced quality of life. What marks this study out is that, unlike previous research, the women who took part didn't face any cultural pressures over the sex of their baby. And women reported lower quality of life following the birth of a boy, even if they didn't suffer from depression.

Liquid water found flowing on Mars? Not yet
Liquid water has not been found on the Martian surface within the last decade after all, according to new research. The finding casts doubt on the 2006 report that the bright spots in some Martian gullies indicate that liquid water flowed there sometime since 1999. The researchers took advantage of the detailed topographic data derived from images of Mars taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter.

The condition occurs when fat accumulates on the liver and leads to significant inflammation and scarring of the liver. Geisinger and Celera have formed an academic entrepreneurial collaboration to investigate this key health problem.

Scientists discover new species of giant elephant-shrew
Although there is unquestionably much left to be discovered about life on Earth, charismatic animals like mammals are usually well documented, and it is rare to find a new species today -- especially from a group as intriguing as the elephant-shrews, monogamous mammals found only in Africa with a colorful history of misunderstood ancestry.

Of mice and men ... and kidney stones
Kidney stones are very common -- and painful -- in men. About three in 20 men (one in 20 women) in developed countries develop them at some stage. Mice, however, rarely suffer though the precise reasons are unknown. Jeffrey S. Clark and colleagues, writing in the Journal of Physiology, have come up with some answers.

DNA of the common black rat has shed light on the ancient spread of rats, people and diseases around the globe. Studying the mitochondrial DNA of 165 black rat specimens from 32 countries around the world, an international team of scientists has identified six distinct lineages in the black rat's family tree, each originating from a different part of Asia.

UNH-NOAA ocean mapping expedition yields new insights into arctic depths
New Arctic sea floor data released today by the University of New Hampshire and the National Oceanic and Atmospheric Administration suggests that the foot of the continental slope off Alaska is more than 100 nautical miles farther from the US coast than previously assumed. The data, gathered during a recent mapping expedition north of Alaska, could support US rights to natural resources of the sea floor beyond 200 nautical miles from the coast.

Brain waves pattern themselves after rhythms of nature
The same rules of physics that govern molecules as they condense from gas to liquid, or freeze from liquid to solid, also apply to the activity patterns of neurons in the human brain. University of Chicago mathematician Jack Cowan will offer this and related insights on the physics of brain activity this week in Boston during the annual meeting of the American Association for the Advancement of Science.

'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
Catalysts typically break down an oxygen molecule into two identical atoms that behave the same. But on a titanium oxide catalyst, the two atoms of a split oxygen molecule act differently: one fills a vacant spot on the catalytic surface and the other acquires extra energy and can move away. If the finding turns out to be important to reactivity, it might also be useful in hydrogen production or to break down pollutants.

First global malaria map in decades shows reduced risk
About 35 percent of the world's population is at risk of contracting deadly malaria, but many people are at a lower risk than previously thought, raising hope that the disease could be seriously reduced or eliminated in parts of the world.

Drug for anemic cancer patients raises risk of death
Millions of cancer patients take drugs to boost their red blood cells and health when they become anemic after chemotherapy. But a new study by Northwestern University's Feinberg School of Medicine shows these drugs, called erythropoiesis-stimulating agents, actually raise patients' risk of death by 10 percent, possibly by stimulating the growth of cancer cells.

Does socializing make us smarter?
Humans are social animals; we spend much of our time with others in groups. We are also wise. It is not our size, speed, or strength that distinguishes us from other mammals, but our intelligence. How might these two features -- being social and being smart -- go together? Research published by SAGE in the February 2008 issue of Personality and Social Psychology Bulletin provides novel information about the relation between being social and being smart.
