Taking daily supplements of selenium and/or vitamin E appears to have no significant effect on the development of age-related cataracts in men, according to new findings from the Selenium and Vitamin E Cancer Prevention Trial (SELECT) Eye Endpoints (SEE) Study.  

Some research, including animal studies, has suggested that dietary nutrients can have an effect on the onset and progression of cataracts. Vitamin E and selenium are of particular interest.

There are few things as spectacular as flying into Pennsylvania in the autumn. The myriad vibrant colors in the trees inspire people to take jaunts into the countryside. 

That will still happen in the future, it may just come later next century, according to new research, because climate change could postpone fall leaf peeping in some areas of the United States as summer temperatures linger later into the year.

The paper birch, a popular foliage tree that is the state tree of New Hampshire, could change color one to three weeks later by the end of the century, Princeton researchers write

An international research consortium has found that longer telomeres increase the risk of melanoma.

Researchers have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port. Its processing algorithm is faster, so it can give the robot feedback in real time. 

The sensor is an adaptation of a technology called GelSight, which was developed by the lab of Edward Adelson, the John and Dorothy Wilson Professor of Vision Science at MIT, first described in 2009. The new sensor is less sensitive than the original GelSight sensor, which could resolve details on the micrometer scale, but it's smaller and faster.

For future astronauts, the process of suiting up may go something like this: Instead of climbing into a conventional, bulky, gas-pressurized suit, an astronaut may don a lightweight, stretchy garment, lined with tiny, musclelike coils. She would then plug in to a spacecraft's power supply, triggering the coils to contract and essentially shrink-wrap the garment around her body.

The skintight, pressurized suit would not only support the astronaut, but would give her much more freedom to move during planetary exploration. To take the suit off, she would only have to apply modest force, returning the suit to its looser form.

A new review of literature suggests that while domestic violence rates are higher for homosexual couples, they aren't as high as previous studies have found, and the authors of the paper say the minority stress model may explain the high prevalence rates.

Previous studies indicate that domestic violence affects up to 75 percent of lesbian, gay and bisexual individuals. A lack of representative data and underreporting of abuse paints an incomplete picture of the true landscape, suggesting even higher rates. By comparison, 25 percent of heterosexual women report domestic abuse while heterosexual men have rates much lower.
