Competition May Be Reason For Bigger Brain
For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition.

A urine test for appendicitis?
Appendicitis is the most common childhood surgical emergency, but the diagnosis can be challenging, especially in children, often leading to either unnecessary surgery in children without appendicitis, or a ruptured appendix and serious complications when the condition is missed.

Underground cave dating from the year 1 A.D. exposed in Jordan Valley
An artificial underground cave, the largest in Israel, has been exposed in the Jordan Valley in the course of a survey carried out by the University of Haifa's Department of Archaeology. Prof. Adam Zertal, who headed the excavating team, reckons that this cave was originally a large quarry during the Roman and Byzantine era and was one of its kind.

Tumor suppressor gene in flies may provide insights for human brain tumors
In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor.

Mouse model of Parkinson's reproduces nonmotor symptoms
The classic symptoms of Parkinson's disease involve tremor, stiffness and slow movements. Over the last decade, neurologists have been paying greater attention to non-motor symptoms, such as digestive and sleep problems, loss of sense of smell and depression.

Inflammation markers linked more with fatal than nonfatal cardiovascular events in elderly
A study published this week in the open access journal PLoS Medicine shows that for elderly people at risk of cardiovascular disease, the presence of inflammatory markers in the blood can identify that an individual is at a higher risk of a fatal rather than a non-fatal heart attack or stroke.
