'Mitochondrial Eve' Research: Humanity Was Genetically Divided For 100,000 Years
Humanity was genetically divided for as much as 100,000 years, according to new findings. Climate change, reduction in populations and harsh conditions may have caused and maintained the separation.
Molecular 'Clock' Could Predict Risk For Developing Breast Cancer
A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help researchers more accurately determine a woman's risk for developing breast cancer and provide a new approach for treatment.
El Niño May Have Been Factor In Magellan's Pacific Voyage
Archaeologists show that Ferdinand Magellan's historic circumnavigation of the globe was likely influenced in large part by unusual weather conditions -- including what we now know as El Niño -- which eased his passage across the Pacific Ocean, but ultimately led him over a thousand miles from his intended destination.
Risk Of Death Persists In Heart Patients With Acute Kidney Injury, Study Shows
Acute kidney injury, a common complication of cardiac surgery during hospitalization, is linked to increased and prolonged risk of death in heart attack patients who have been discharged from the hospital, according to a study published in Archives of Internal Medicine.
Nanotechnology In Reverse Uses Red Blood Cell To Calibrate Atomic Force Microscope
Nanotechnology researchers have shown that they can use a red blood cell to calibrate a sensitive instrument, an atomic force microscope. An atomic force microscope uses a tiny lever that runs over the surface of an object. Small deflections of the tip are read and translated to produce an image of the object's surface. However, accurate calibration of the springiness of the tip is difficult.
Having Less Power Impairs The Mind And Ability To Get Ahead, Study Shows
New research appearing in Psychological Science suggests that being put in a low-power role may impair a person's basic cognitive functioning and thus, their ability to get ahead.
Crystal (Eye) Ball: Visual System Equipped With 'Future Seeing Powers'
Catching a football. Maneuvering through a room full of people. Jumping out of the way when a golfer yells "fore." Most would agree these seemingly simple actions require us to perceive and quickly respond to a situation. An assistant professor of cognitive science argues they require something more -- our ability to foresee the future.
Most Effective Initial Therapy For HIV-1 Infection Identified
In the largest study of its kind to evaluate commonly used HIV drugs, researchers confirmed that one of the most frequently prescribed triple drug combinations for initial HIV infection is indeed the most effective at suppressing HIV. The study also found that a two-drug regimen performed comparably to the triple-drug regimens.
Deep Sea Methane Scavengers Captured
Scientists succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane into the atmosphere. These microorganisms that oxidize methane anaerobically are an important component of the global carbon cycle and a major sink for methane on Earth. Methane - a more than 20 times stronger greenhouse gas than carbon dioxide - constantly seeps out large methane hydrate reservoirs in the ocean floors, but 80 percent of it are immediately consumed by these microorganisms.
Prostate Cancer Increases The Risk Of Bone Fracture, Study Shows
As unlikely as it sounds, scientists have shown that there is a link between prostate cancer and a higher risk of bone fracture. Men with prostate cancer face a 50% higher risk of fracture, which increases to nearly doubled risk if they are receiving treatment.
Firearms Microstamping Feasible But Variable, Study Finds
New technology to link cartridge cases to guns by engraving microscopic codes on the firing pin is feasible, but did not work equally well for all guns and ammunition tested in a pilot study by researchers from the forensic science program at UC Davis. Microstamping technology uses a laser to cut a pattern or code into the head of a firing pin or another internal surface.
Mixed Results For Late-talking Toddlers
New research findings from the world's largest study on language emergence have revealed that one in four late-talking toddlers continue to have language problems by age seven.
Rapid, Dramatic 'Reverse Evolution' Documented In Tiny Fish Species
Evolution is supposed to inch forward over eons, but sometimes, at least in the case of a little fish called the threespine stickleback, the process can go in relative warp-speed reverse, according to a new study. The adaptation coincides with the '60s cleanup of toxic pollution in Seattle's Lake Washington.
