goodNo one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study suggests scientists' best predictions about global warming might be incorrect.

Research indicates that a baby born to an older mother may have a slightly increased risk for many of the cancers that occur during childhood.
Scientists have successfully conducted the first remote detection of a harmful algal species and its toxin below the ocean's surface.
Obesity very often leads to insulin resistance, and now researchers have uncovered another factor behind that ill consequence. The newly discovered culprit is a protein, called PEDF for short, that is secreted by fat cells. They also report evidence to suggest that specifically blocking PEDF action may reverse some of the health complications that come with obesity.
In honor of scientist and astronomer Nicolaus Copernicus (1473-1543), the discovering team have suggested the name "copernicium" with the element symbol "Cp" for the new element 112.
Nineteenth century infant deaths attributed to smothering and overlaying, by either a co-sleeper or bedding, were in all likelihood crib deaths, or Sudden Infant Death Syndrome (SIDS). These deaths would have been mislabeled by lawmakers as neglect and even infanticide, because SIDS had not yet been identified, according to new research.
Venus Express has charted the first map of Venus's southern hemisphere at infrared wavelengths. The new map hints that our neighboring world may once have been more Earth-like, with both a plate tectonics system and an ocean of water.
Many studies indicate that caloric restriction extends life spans in fruit flies, mice and, most recently, rhesus monkeys, apparently by slowing the aging process. But virtually all these studies have been performed in sterile environments, on animals raised under relatively pathogen-free conditions. So researchers decided to see if reduced caloric intake also helps creatures cope with infection.
Chemistry researchers have developed a simple but effective way of lifting fingerprints. The technique involves studying the chemical and physical interactions occurring between the metal and the fingerprint sweat deposit. Using advanced surface imaging techniques, such as an atomic force microscope, nanoscale observations of fingerprinted brass samples can identify optimum conditions to promote the natural enhancement of the fingerprint.
Condom use is associated with a reduced risk of contracting herpes simplex virus 2, according to a report based on pooled analysis of data from previous studies.
Researchers have created a reversible route to generate aluminum hydride, a high capacity hydrogen storage material. This achievement is not only expected to accelerate the development of a whole class of storage materials, but also has far reaching applications in areas spanning energy technology and synthetic chemistry.
Men and women who walk or ride a bike to work appear more fit, and men are less likely to be overweight or obese and have healthier triglyceride levels, blood pressure and insulin levels, according to a new report.
In the French cave of Arago, scientists has analyzed the dental wear of the fossils of herbivorous animals hunted by Homo heidelbergensis. It is the first time that an analytical method has allowed the establishment of the length of human occupations at archaeological sites. The key is the last food that these hominids consumed.
Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's, according to new research.
A key constituent in New England salt marshes may be imperiled by global warming, a new study has found. Experiments show that warmer temperatures cause a spectrum of plants known as forbs to disappear.
Obesity, among other factors, is strongly associated with an increased risk of rapid cartilage loss, according to a new study.
Since its discovery a few years ago, graphene has climbed to the top of the heap of new materials poised to transform the electronics and nanotechnology landscape. Now scientists have made the first measurement of a fundamental property of graphene, known as quantum capacitance. This crucial variable should prove invaluable to researchers pushing the existing limits of innovation in microchips, chemical sensing instruments, biosensors, ultracapacitance devices and flexible displays.
Researchers have developed a method to analyze the personality of people with psychopathologic disorders by means of their drawings. It consists of a series of Graphic Projective Tests (TPG) where patients draw what a psychologist requests. Each element of the picture has a meaning and it will give information about conscious and unconscious aspects of the analyzed person.
A large study of patients with mild cognitive impairment revealed that cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease. The findings are a major step forward in the march toward earlier diagnoses of the debilitating disease.
