Science 2.0 - Apr 18 2019 - 07:04

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.

Godly Kings: How War, Politics And Propaganda Helped Bring Down The Mayans

Science 2.0 - Apr 16 2019 - 11:04
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.

Genetic Engineering Removes Antibiotic Resistance From Bacteria

Science 2.0 - Apr 12 2019 - 17:04
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.

Taste Is Complex And It Changes As We Age

Science 2.0 - Apr 11 2019 - 10:04

Taste is a complex phenomenon. We do not experience the sensation through a single sense (as we would when we see something using our sense of sight, for example) but rather it is made up of the five senses working together to allow us to appreciate and enjoy food and drink. Initial visual inspection of food indicates if we would consider consuming it. Then, when eating, smell and flavor combine to allow us to perceive a taste. Meanwhile, the mix of ingredients, texture and temperature can further impact how we experience it.

Supplements are a huge industry that ballooned after President Bill Clinton turned the Dietary Supplement Health and Education Act of 1994 into law and took control of the controversial industry away from the U.S. Food and Drug Administration in return for a weak disclaimer that the FDA had not evaluated their claims - "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease" all while suggesting they do exactly that.

40 Years Later, Jean-Pierre Luminet's Black Hole Image Looks Surprisingly Accurate

Science 2.0 - Apr 10 2019 - 10:04
Published in 1979 in Astronomy and Astrophysics, it had a worldwide impact, especially since this type of object was still highly theoretical. It is not an artist's view but an image based on the then supposed physical properties of a black hole and its gas disc, such as its rotation rate and temperature, and on Einstein's general theory of relativity. Luminet envisioned it as a black circle, which had not yet become known as the shadow of the black hole, in the centre of a luminous accretion disc, with one side clearly brighter than the other.
