But why have previous studies not reached these same results if they are so obvious?

"It is difficult to conduct reliable epidemiological research in brain aneurysms. The past 10 years have seen a distortion in the field due to a very limited group of researchers determining the direction for research. Now the situation is clearly changing, and clinically reasonable, population-based studies using non-selected data are on the rise again," states Docent Miikka Korja of the HUCS neurosurgery clinic.

Despite worsening economic conditions for those at the bottom, infant health has steadily improved among the most disadvantaged Americans, according to a review published in Science by Princeton University's Woodrow Wilson School of Public and International Affairs.

The researchers cite programs and policies like Medicaid, the Supplemental Feeding Program for Women, Infants, and Children (WIC) and the Food Stamp program – now known as Supplemental Nutrition Assistance Program (SNAP) – as the driving forces behind such marked improvements.

NEW YORK, NY (May 22, 2014) — Researchers have discovered how a gene commonly linked to obesity—FTO—contributes to weight gain. The study shows that variations in FTO indirectly affect the function of the primary cilium, a little-understood hair-like appendage on brain and other cells. Specific abnormalities of cilium molecules, in turn, increase body weight, in some instances, by affecting the function of receptors for leptin, a hormone that suppresses appetite. The findings, made in mice, suggest that it might be possible to modify obesity through interventions that alter the function of the cilium, according to scientists at Columbia University Medical Center (CUMC).

LA JOLLA, CA—May 21, 2014—In surprise findings, scientists at The Scripps Research Institute (TSRI) have discovered that a protein with a propensity to form harmful aggregates in the body when produced in the liver protects against Alzheimer's disease aggregates when it is produced in the brain. The results suggest that drugs that can boost the protein's production specifically in neurons could one day help ward off Alzheimer's disease.

"This result was completely unexpected when we started this research," said TSRI Professor Joel N. Buxbaum, MD. "But now we realize that it could indicate a new approach for Alzheimer's prevention and therapy."

RAPID RESISTANCE to vemurafenib – a treatment for a type of advanced melanoma, the deadliest form of skin cancer – could be prevented by blocking a druggable family of proteins, according to research* published in Nature Communications today (Thursday).

Scientists at the Cancer Research UK Manchester Institute, based at the University of Manchester, have revealed the MLK family of four enzymes 'undoes' the tumour-shrinking effects of vemurafenib**.

Around half of metastatic melanomas – aggressive skin cancer that has spread to other parts of the body – are caused by a fault in the cell-growth gene BRAF, causing the signal telling cells to multiply to be permanently switched on.

The so-called symbiotic relationship between trees and the fungus that grow on their roots may actually work more like a capitalist market relationship between buyers and sellers, according to the new study published in the journal New Phytologist.
