Regulators Take a Close Look at Microsoft-Yahoo Deal

The 10-year search-engine deal between Microsoft and Yahoo is under scrutiny. The July 29 deal between the two behemoths is being closely monitored by U.S. antitrust regulators, and both companies are in talks with officials in the European Union. The U.S. Justice Department last week asked the companies for additional information on the Internet search deal, a source told Reuters. It hasn't...

Introduced Japanese white-eyes pose major threat to Hawaii's native and endangered birds

In the late 1920s, people intentionally introduced birds known as Japanese white-eyes into Hawaiian agricultural lands and gardens for purposes of bug control. Now, that decision has come back to bite us. A recent increase in the numbers of white-eyes that live in old-growth forests is leaving native bird species with too little to eat, according to a report published online on September 17th in...

New links between epilepsy and brain lipids

In mice that are missing a protein found only in the brain, neural signals "go crazy," leaving the animals with epileptic seizures from a young age, researchers have found. The report in the September 18th Cell, a Cell Press publication, details what it is that happens when the protein encoded by plasticity related gene-1 (PRG-1) gets lost, revealing an important fine-tuning mechanism for brain...

New vitamin K analysis supports the triage theory

An important analysis conducted by Children's Hospital Oakland Research Institute scientists suggests the importance of ensuring optimal dietary intakes of vitamin K to prevent age-related conditions such as bone fragility, arterial and kidney calcification, cardiovascular disease, and possibly cancer (1). Vitamin K is concentrated in dark green plants such as spinach or Swiss chard, and is either...

Proposal to reintroduce Iberian lynx on abandoned agricultural land

Spanish scientists have developed a model to identify the agricultural areas with the greatest potential for restoring the habitat of the Iberian lynx (Lynx pardinus), which is at risk of extinction. The study shows that olive groves with low production close to the Natural Park of the Sierra de Cardeña y Montoro, in Córdoba - which is the only place, along with Doñana, where this species...

Rare genetic disease successfully reversed using stem cell transplantation

A recent study by Scripps Research Institute scientists offers good news for families of children afflicted with the rare genetic disorder, cystinosis. In research that holds out hope for one day developing a potential therapy to treat the fatal disorder, the study shows that the genetic defect in mice can be corrected with stem cell transplantation.

Solar cycle driven by more than sunspots

Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun's impact on Earth over the course of the 11-year solar cycle. The study, led by scientists at the National Center for Atmospheric Research (NCAR) and the University of Michigan, finds that Earth was bombarded last year with high levels of solar energy at a time when...

Genetic Hint For Ridding The Body Of Hepatitis C

More than seventy percent of people who contract Hepatitis C will live with the virus that causes it for the rest of their lives and some will develop serious liver disease including cancer. However, 30 to 40 percent of those infected somehow defeat the infection and get rid of the virus with no treatment. Researchers have now discovered the strongest genetic alteration associated with the ability...

New Insights Into Cardiac Aging

Researchers have found that the conserved protein d4eBP modulates cardiac aging in Drosophila (fruit flies). The team also found that d4eBP, which binds to the protein dEif4e, protects heart function against aging.

Zinc Deficiences A Global Concern

Other vitamins and nutrients may get more headlines, but experts say as many as two billion people around the world have diets deficient in zinc -- and studies are raising concerns about the health implications this holds for infectious disease, immune function, DNA damage and cancer. One new study has found DNA damage in humans caused by only minor zinc...
