In a study of older women with newly diagnosed stage I to III breast cancer, approximately one in five lost the ability to complete some of the basic tasks necessary for independent living within one year of initiating treatment. The study also found that a simple survey can help identify which women are at risk of such functional decline. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

CAMBRIDGE, MA -- Around 4.6 billion years ago, the universe was a chaos of collapsing gas and spinning debris. Small particles of gas and dust clumped together into larger and more massive meteoroids that in turn smashed together to form planets. Scientists believe that shortly after their formation, these planets -- and particularly Mercury -- were fiery spheres of molten material, which cooled over millions of years.

Now, geologists at MIT have traced part of Mercury's cooling history and found that between 4.2 and 3.7 billion years ago, soon after the planet formed, its interior temperatures plummeted by 240 degrees Celsius, or 464 degrees Fahrenheit.

LOS ALAMOS, N.M., June 27, 2016--The discovery of manganese oxides in Martian rocks might tell us that the Red Planet was once more Earth-like than previously believed. A new paper in Geophysical Research Letters reveals that NASA's Curiosity rover observed high levels of manganese oxides in Martian rocks, which could indicate that higher levels of atmospheric oxygen once existed on our neighboring planet. This hint of more oxygen in Mars' early atmosphere adds to other Curiosity findings--such as evidence of ancient lakes--revealing how Earth-like our neighboring planet once was.

Rats given midazolam, an anti-anxiety medication, were less likely to free trapped companions because the drug lessened their empathy, according to a new study by University of Chicago neuroscientists.

Tropical Cyclone 02A developed in the Northern Indian Ocean's Arabian Sea as NASA's Aqua satellite passed overhead and analyzed the storm in infrared light and NASA's Terra satellite captured a visible look at the storm.

BIRMINGHAM, Ala. - Laundry pod detergents are far more likely to cause poisoning injuries in young children than are nonpod laundry detergents, and are four times more likely to lead to hospitalization, according to findings published today from researchers at the University of Alabama at Birmingham.

The study, published in Injury Prevention, estimates there were almost 36,000 cases of injury due to all types of laundry detergent in U.S. emergency departments between 2012 and 2014.
