Due to increased regulations, a culture war against pharmaceutical corporations, and the high costs of trials, companies have increasingly allowed early taxpayer-funded biomedical research to spread the risk among hundreds of millions of people. The pace of invention has slowed considerably and it may be because of academic culture, according to a new study.

An analysis of patented university inventions has revealed early bottlenecks on the path to commercialization and the authors suggest that better communication of basic research results during the discovery stage could lead to faster commercialization down the road.

Tropical Storm Karina was weakening on August 20 when NASA's Terra satellite passed overhead. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra snapped a visible image of Tropical Storm Karina on August 20 at 19:40 UTC (3:40 p.m. EDT). The MODIS image showed that a thick band of strong thunderstorms spiraled into Karina's center from the southeast. The band of thunderstorms wrapped around Karina's eastern and northern quadrants, spiraling into the center from the west, making the tropical cyclone look like the number nine.

A team of researchers  is a step closer to solving the mystery of how lizards regenerate their tails. They have found the genetic "recipe", which involves genetic ingredients in just the right mixture and amounts.

The scientists used molecular and computer analysis tools to examine the genes turned on in tail regeneration. The team studied the regenerating tail of the green anole lizard (Anolis carolinensis), which when caught by a predator, can lose its tail and then grow it back. 

When salmon encounter turbulent, fast-moving water, such as rapids or areas downstream of dams, they must move upstream using a behavior known as "burst swimming" that is similar to sprinting for humans.

A common orb-weaving spider may grow larger and have an increased ability to reproduce when living in urban areas, according to ecologists from the University of Sydney.

The Paleolithic inhabitants of modern-day Spain may have eaten snails 30,000 years ago - 10,000 years earlier than their Mediterranean neighbors, according to a recent paper.
