Maternal obesity speeds up aging in offspring
The effects of maternal obesity even pass across generations to offspring, accelerating the rate of aging of metabolic problems that occur in normal life.

Solution to Ice Age ocean chemistry puzzle
New research into the chemistry of the oceans during ice ages is helping to solve a puzzle that has engaged scientists for more than two decades. At issue is how much of the CO2 that entered the ocean during ice ages can be attributed to the 'biological pump', where atmospheric carbon is absorbed by phytoplankton and sequestered to the seafloor as organisms die and sink.
Read moreNervous system's role in age-related weakness
A study finds new evidence to support the belief that the nervous system plays an important role in age-related weakness.
Read moreChildren associate white, but not black, men with 'brilliant' stereotype, new study finds
The stereotype that associates being 'brilliant' with white men more than white women is shared by children regardless of their own race, finds a team of psychology researchers. By contrast, its study shows, children do not apply this stereotype to black men and women.
Read moreProtective mediators can help heal injured tendon cells by attacking inflammation
Tendon tears, both to the rotator cuff and Achilles heel, are common injuries, especially in aged individuals. Painful and disabling, they can adversely impact quality of life. New approaches are required to help patients suffering from chronic tendon injuries. A novel study identified mediators that promote resolution of inflammation as potential new therapeutics to push chronically injured tendons down an inflammation-resolving pathway.
Read moreBrain mechanisms have potential to block arthritis pain
Because pain is a complex condition, treating it efficiently continues to pose challenge for physicians. Past pain research typically has focused upon the spinal cord or the peripheral areas of the nervous system located outside the spinal cord and brain. However, a research team recently investigated how some mechanisms in the brain contribute to pain.
Read moreNew science on cracking leads to self-healing materials
Cracks in the desert floor appear random to the untrained eye, even beautifully so, but the mathematics governing patterns of dried clay turn out to be predictable — and useful in designing advanced materials.
Read moreSystem can minimize damage when self-driving vehicles crash
Engineers have developed decision-making and motion-planning technology to limit injuries and damage when self-driving vehicles are involved in unavoidable crashes. After recognizing that a collision of some kind is inevitable, the system works by analyzing all available options and choosing the course of action with the least serious outcome.
Read moreIllegal urban off-road vehicles as risky as motorcycles in cities
People who illegally ride off-road vehicles, such as dirt bikes and all-terrain vehicles, on city streets suffer similar crash injuries as motorcyclists, but are less likely to die even though many riders don't wear helmets, according to new research.

A new study shows that smoking even a few cigarettes a day is harmful to lungs and that former smokers continue to lose lung function at a faster rate than never-smokers for decades after quitting.
