Regulators Take a Close Look at Microsoft-Yahoo Deal
Sci-Tech Today
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...
Genes controlling insulin can alter timing of biological clock

Many of the genes that regulate insulin also alter the timing of the circadian clock, a new study has found.
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...

The Wall Street Journal announced on Thursday that it will begin charging for access to the newspaper on mobile devices such as the Blackberry or Apple iPhone from October 24.
Combat Exposure May Increase Likelihood Of Newly Reported High Blood Pressure
Military deployment with multiple combat exposures appeared to be a unique risk factor for newly reported hypertension. Specifically, personally witnessing or being exposed to death due to war or disaster was significantly associated with increased likelihood of newly self-reported hypertension both at single and multiple...
Scientists Complete First Geological Global Map Of Jupiter's Satellite Ganymede
Scientists have assembled the first global geological map of Jupiter's moon Ganymede -- the solar system's largest moon -- and in doing so have gathered new evidence into the formation of the large, icy satellite.
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...
Natural Hydrogel Helps Heal Spinal Cord, Researcher Finds
Injecting biomaterial gel into a spinal cord injury site provides significantly improved healing, new research has shown. The project indicates that a "practical path" to treatment may be found for spinal injury patients.
Laser Processes Promise Better Artificial Joints, Arterial Stents
Researchers are developing technologies that use lasers to create arterial stents and longer-lasting medical implants that could be manufactured 10 times faster and also less expensively than is now possible.
Zero Tolerance, Zero Effect, Says Expert
Zero tolerance laws have zero effect, says one expert, who analyzed data from 30,000 fatalities in nighttime accidents involving drivers under 21.
Cases Of Liver Cancer Reduced In Younger Population Vaccinated For Hepatitis B
A 20-year follow-up study revealed a dramatic drop in liver cancer cases among 6- to 19-year-olds who were vaccinated for the hepatitis B virus at birth, according to a new study.
During CPR, More Chest Compressions Mean More Saved Lives
The chance that a person in cardiac arrest will survive increases when rescuers doing cardiopulmonary resuscitation (CPR) spend more time giving chest compressions, according to a multi-center study.
Web-based Screening And Intervention May Reduce Drinking In University Students
Web-based screening and personalized interventions for alcohol use may reduce drinking in undergraduate students, according to a new report.
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...
Moore directs CRTC to tackle fee-for-carriage
Canadian Heritage Minister James Moore has waded into television's fiery fee-for-carriage debate, directing Canada's broadcast regulator to hold a hearing and report back to the government.
