Why do good people do bad things? It's a question that has been pondered for centuries, and new research may offer some insight. 

In a series of experiments with undergraduates, participants who anticipated a temptation to act unethically were less likely to then behave unethically, relative to those who did not. These participants also were less likely to endorse unethical behavior that offered short-term benefits, such as stealing office supplies or illegally downloading copyrighted material.  

There are about 10,000 compounds used to make cosmetics, and they are monitored by government agencies in a way that products go inside the body, such as 'alternative' medicine and supplements, are not.

If you have gone to a new web page and seen an advertisement based on things you looked at in your browser history, you have likely been impressed or creeped out. You can thank MIT for a lot of this “programmatic marketing” - and rocket science. It is also why you will probably never make any money on your blog. 

Prostate cancer is the second most common type of cancer in men and is predicted to result in an estimated 220,00 cases in the United States in 2015.

The modern sedimentary environment contains a diversity of microbes that interact very closely with the sediments, sometimes to such an extent that they form "biosediments."

But can such a phenomenon be fossilized? How far back in time can "biosedimentation" be traced? In a study for Geology, Frances Westall and colleagues examine some of the oldest rocks on Earth, in the Barberton Greenstone Belt, South Africa (older than 3.3 billion years), to answer this question.

Westall and colleagues use multi-scale methods to document the simultaneous presence of diverse types of microorganisms, including phototrophs and chemotrophs, directly interacting with coastal volcanic sediments that were bathed by hydrothermal fluids.

Lethal wounds identified on a human skull may indicate one of the first cases of murder in human history, according to a new paper.

The archaeological site, Sima de los Huesos in northern Spain, is located deep within an underground cave system and contains the skeletal remains of at least 28 individuals that date to around 430,000 years ago, during the Middle Pleistocene. The only access to the site is through a 13-meter deep vertical shaft, and how the human bodies arrived there remains a mystery.
