Study links chemicals widely found in plastics and processed food to elevated blood pressure in children and teens

Plastic additives known as phthalates (pronounced THAL-ates) are odorless, colorless and just about everywhere: They turn up in flooring, plastic cups, beach balls, plastic wrap, intravenous tubing and—according to the Centers for Disease Control and Prevention—the bodies of most Americans. Once perceived as harmless, phthalates have come under increasing scrutiny. A growin

Changing cancer's environment to halt its spread

By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, a trans-Atlantic research team has identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer. The findings suggest that a prosaposin-based drug could potentially block metastasis in a va

Estimates reveal low population immunity to new bird flu virus H7N9 in humans

The level of immunity to the recently circulating H7N9 influenza virus in an urban and rural population in Vietnam is very low, according to the first population level study to examine human immunity to the virus, which was previously only found in birds. The findings have implications for planning the public health response to this pandemic threat.

Going green: Nation equipped to grow serious amounts of pond scum for fuel

A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year in the United States, one-twelfth of the country's yearly needs.

Minus environment, patterns still emerge

Environment is not the only factor in shaping regulatory patterns -- and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.

14 closely related crocodiles existed around 5 million years ago

Nowadays, the most diverse species of crocodile are found in northern South America and Southeast Asia: As many as six species of alligator and four true crocodiles exist, although no more than two or three ever live alongside one another at the same time. It was a different story nine to about five million years ago, however, when a total of 14 different crocodile species existed and at least sev

Origins of human culture linked to rapid climate change

Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research.

The pirate ant: A new species from the Philippines with a bizarre pigmentation pattern

Scientists discovered a new enigmatic species of ant coming from the Philippines. Cardiocondyla pirata or the pirate ant engages the imagination with a bizarre pigmentation pattern that has no equivalent worldwide. The female castes in the colonies of these species can be recognized by a distinctive dark stripe across the eyes that resembles a pirate eye patch, which inspired the authors to

Small but speedy: Short plants live in the evolutionary fast lane

Biologists have known for a long time that some creatures evolve more quickly than others. Exactly why isn't well understood, particularly for plants. But it may be that height plays a role, says Robert Lanfear of Australian National University and the U. S. National Evolutionary Synthesis Center.

Video: Allosaurus fed more like a falcon than a crocodile, new study finds

The mighty T. rex may have thrashed its massive head from side to side to dismember prey, but a new study shows that its smaller cousin Allosaurus was a more dexterous hunter and tugged at prey more like a modern-day falcon.
