Testosterone is the main sex hormone in men. It’s best known for its role in the development of male sexual characteristics and physical features, but there are also many surprising and lesser known functions of testosterone that make it an important hormone in health and disease. Identifying whether someone has too much or too little testosterone can predict future diseases and even treat them. But knowing what is high, low or normal for an individual isn’t straightforward.

These days, anybody with an internet connection can be a publisher.

This distinction has become more important than ever in light of two recent events.

The discovery of an ancient painted vase in the Central America lowlands offers new clues into the mysterious breakdown of ancient Maya civilization - because it bears one of the longest hieroglyphic texts ever found.

The shattered vessel was discovered in excavations at the Maya site of Baking Pot in Belize, found amid artifacts associated with the abandonment of the royal palace complex. The fragments were found in a corner near a palace entrance. The archeology team also unearthed blades, pendants, inkpots, fragments of flutes — and human bones - in burial sites.

Surveys show that on issue after issue, women are more liberal than men, save for one: Men are more likely than women to support the legalization of marijuana.

The European Commission pays close attention to document the work of the projects that benefited of its funding. With that intent, the AMVA4NewPhysics network has been described, along with its goals, in a 2016 article on the Horizon magazine.

People choose a life partner who is likely to have a comparable life expectancy and who share similar risks of illnesses - such as high blood pressure or heart disease - according to a genetic study.

The conjugative transfer of anti-antibiotic resistance genetic elements could lead to development of probiotic bacteria that re-sensitize resistant bacteria to antibiotics, providing a solution to a crucial problem - how to get new antibiotics when countries cap what companies can charge for medicine, meaning they might never be profitable.

Bacteria become resistant due to the use of antibiotics and the exchange of resistance genes between bacteria.

First, this is totally harmless. Tiny and far away, shrouded with dust and gas. They can only see it using radio waves that go through the dust. And the photo of course changes nothing, we've know it is there for a long time away. This is a screenshot from the press conference:

And over four separate days:

Short summary here

Using records pediatric health clinics, specialized programs for children with developmental disabilities, and special education records along with a review of the abstracted evaluations by trained clinicians using a standardized case definition and method (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) diagnostic criteria) a new Centers for Disease Control and Prevention analysis has found that diagnoses in the sites they used were up 27 percent from 2010 to 2014.
