Science Daily- Among apes, teeth are made for the toughest timesThe teeth of some apes are formed primarily to handle the most stressful times when food is scarce, according to new research. The findings imply that if humanity is serious about protecting its close evolutionary cousins, the food apes eat during these tough periods -- and where they find it -- must be included in conservation efforts.
- Microcephaly genes associated with human brain sizeScientists have shown that common variations in genes associated with microcephaly -- a neuro-developmental disorder in which brain size is dramatically reduced -- may explain differences in brain size in healthy individuals as well as in patients with neurological and psychiatric disorders.
- Pomegranates: Latest weapon in the fight against MRSAPomegranates have already been hailed as a super-food but a team of scientists has found a new use for the deep red fruit. The team has discovered that the rind can be turned into an ointment for treating MRSA and other common hospital infections.
- Twin study identifies factors associated with skin agingSmoking, being heavier, not using sunscreen and having had skin cancer appear to be associated with sun damage and aging of skin on the face, according to a report based on a study of twins.
- Scientists shed light on a mysterious particle, the neutrinoPhysicists have begun looking deep into the Earth to study some of nature's weirdest particles -- neutrinos.
- Discrimination in the citations that scientists useScience does not have to be altruistic. In fact, most of the time it is egotistic, according to a study by researchers in Spain that analyzes the discrimination that exists in citations of scientific articles in articles where researchers publish their results.
- Next-generation lens promises wider view, greater detailEngineers have created a new generation of lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail.
- Compound found to safely counter deadly bird fluA study suggests that a new compound, one on the threshold of final testing in humans, may be more potent and safer for treating "bird flu" than the antiviral drug best known by the trade name Tamiflu.
- Fisheries and aquaculture face multiple risks from climate changeMarine capture fisheries already facing multiple challenges due to overfishing, habitat loss and weak management are poorly positioned to cope with new problems stemming from climate change, a new study suggests.
- Genomes of identical twins reveal epigenetic changes that may play role in lupusIdentical twins look the same and are nearly genetically identical, but environmental factors and the resulting cellular changes could cause disease in one sibling and not the other. Scientists have studied twins discordant for the autoimmune disease lupus, mapping DNA modifications across the genome and shedding light on epigenetic changes that may play a r […]
