Researchers at the University of Edinburgh have shown that hormone therapy can extend life in ovarian cancer patients, giving women a new alternative to chemotherapy.

The study has proved for the first time that the targeted use of an anti-oestrogen drug could prolong the life of some patients by up to three years, and delay the use of chemotherapy in others.

Yes, you secretly like giving your money to the government. University of Oregon scientists have found that doing things like donating money to charity or even paying your taxes can give you the same sort of satisfaction you derive from feeding your own hunger pangs.

A cognitive psychologist and two economists gave 19 female participants $100 and then scanned their brains with functional magnetic resonance imaging (fMRI) as they watched their money go to the food bank through mandatory taxation, and as they made choices about whether to give more money voluntarily or keep it for themselves.

Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer’s disease, report researchers at the Salk Institute for Biological Studies. While aging is still the greatest risk factor for Alzheimer’s disease, a number of studies have pointed to stress as a contributing factor.

It may sound counterintuitive to use a microbial protein to improve water quality but some bacteria are doing just that to protect themselves from potentially toxic nanoparticles in their own environments, and clean up crews of the future could potentially do the same thing on a larger scale.

NASA's Hubble Space Telescope has teamed up with the W.M. Keck Observatory to precisely measure the mass of Eris, the largest member of a new class of dwarf planets in our solar system. Eris is 1.27 times the mass of Pluto, formerly the largest member of the Kuiper Belt of icy objects beyond Neptune.

Some advice my dad gave me: "If your wife says she never dreams about sex with another man, she's lying. If she says she never dreams about sex with another woman, she's lying then too."

He may have been on to something. It turns out everyone, men and women alike, dream about sex.

In a detailed study that served to investigate the actual nature and content of sexual dreams across a large sample of dream reports from men and women, approximately eight percent of everyday dream reports from both genders contain some form of sexual-related activity.
