Battle Scars Found On an Ancient Sea Monster
Scars on the jaw of a 120-million-year-old marine reptile suggest that life might not have been easy in the ancient polar oceans. The healed bite wounds were probably made by a member of the same species. Such injuries give important clues about the social behaviour of extinct sea creatures from the time of dinosaurs.

Effects of Climate Change in Arctic More Extensive Than Expected, Report Finds
A much reduced covering of snow, shorter winter season and thawing tundra: The effects of climate change in the Arctic are already here. And the changes are taking place significantly faster than previously thought. This is what emerges from a new research report on the Arctic, presented in Copenhagen this week. Margareta Johansson, from Lund University, is one of the researchers behind the report.

Spitzer Detects Shadow of 'Super-Earth' in Front of Nearby Star
NASA's Spitzer Space Telescope has detected the crossing of a solid planet in front of a star located at only 42 light-years in the constellation Cancer. Thanks to this detection, astronomers know that this "super-Earth" measures 2.1 times the size of our Earth. This is the smallest exoplanet detected in the neighborhood of our Sun.

NASA's Gravity Probe B Confirms Two Einstein Space-Time Theories
NASA's Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.

Transistors Reinvented Using New 3-D Structure
Intel Corporation has announced a significant breakthrough in the evolution of the transistor, the microscopic building block of modern electronics. For the first time since the invention of silicon transistors over 50 years ago, transistors using a three-dimensional structure will be put into high-volume manufacturing. Intel will introduce a revolutionary 3-D transistor design called Tri-Gate, first disclosed by Intel in 2002, into high-volume manufacturing at the 22-nanometer (nm) node in an Intel chip codenamed "Ivy Bridge." A nanometer is one-billionth of a meter.

Reptile 'Cousins' Shed New Light On End-Permian Extinction
The end-Permian extinction, by far the most dramatic biological crisis to affect life on Earth, may not have been as catastrophic for some creatures as previously thought, according to a new study led by the University of Bristol.

Brain Region That Influences Gambling Decisions Pinpointed
When a group of gamblers gather around a roulette table, individual players are likely to have different reasons for betting on certain numbers. Some may play a "lucky" number that has given them positive results in the past -- a strategy called reinforcement learning. Others may check out the recent history of winning colors or numbers to try and decipher a pattern. Betting on the belief that a certain outcome is "due" based on past events is called the gambler's fallacy.

Universal Signaling Pathway Found to Regulate Sleep
Sleeping worms have much to teach people, a notion famously applied by the children's show "Sesame Street," in which Oscar the Grouch often reads bedtime stories to his pet worm Slimy. Based on research with their own worms, a team of neurobiologists at Brown University and several other institutions has now found that "Notch," a fundamental signaling pathway found in all animals, is directly involved in sleep in the nematode C. elegans.

Scientists Afflict Computers With 'Schizophrenia' to Better Understand the Human Brain
Computer networks that can't forget fast enough can show symptoms of a kind of virtual schizophrenia, giving researchers further clues to the inner workings of schizophrenic brains, researchers at The University of Texas at Austin and Yale University have found.

Malaria Mosquitoes Accurately Find Their Way to Smelly Feet
Malaria mosquitoes utilize CO2 from exhaled air to localize humans from afar. In the vicinity of their preferred host, they alter their course towards the human feet. Researcher Remco Suer discovered how female malaria mosquitoes use foot odors in the last meters to guide them to their favoured biting place. Suer, who is defending his doctoral thesis May 9 at Wageningen University, part of Wageningen UR, sees possibilities to disrupt the host seeking behaviour of the malaria mosquito.

New Mineral Discovered: One of Earliest Minerals Formed in Solar System
In the May-June issue of the journal American Mineralogist, a team of scientists announced the discovery of the new mineral krotite, one of the earliest minerals formed in our solar system. It is the main component of an unusual inclusion embedded in a meteorite (NWA 1934), found in northwest Africa. These objects, known as refractory inclusions, are thought to be the first planetary materials formed in our solar system, dating back to before the formation of Earth and the other planets.
