Sea Stars Grow Faster As Water Warms
From Live Science:
Climate change will deal clams, mussels, and other marine bivalves a double whammy. Biologists already expect them to have trouble making their shells because elevated carbon dioxide (CO2) levels will acidify seawater. Now it seems they’ll also have to contend with brawnier predatory starfish.
Bivalves are the preferred prey of the purple ocher sea star (Pisaster ochraceus), a familiar denizen of the intertidal zone along the Canadian and American west coast.

Real-Time Hackers Foil Two-Factor Security
From Technology Review:
One-time passwords are vulnerable to new hacking techniques.
In mid-July, an account manager at Ferma, a construction firm in Mountain View, CA, logged in to the company's bank account to pay bills, using a one-time password to make the transactions more secure.
Yet the manager's computer had a hitchhiker. A forensic analysis performed later would reveal that an earlier visit to another website had allowed a malicious program to invade his computer. While the manager issued legitimate payments, the program initiated 27 transactions to various bank accounts, siphoning off $447,000 in a matter of minutes. "They not only got into my system here, they were able to ascertain how much they could draw, so they drew the limit," says Roy Ferrari, Ferma's president.

The 33 Most Deadly Substances On Earth
Keep well away from the following 33 substances unless you want to end up 6 feet under.
Location: Europe and in the United States.
In Europe, the blossoms vary in color from pale-green or yellow-olive and along both the east and west coasts in the United States. However, they range from white to light brown in the rest of the United States.
Amanitin can be detected in the blood almost immediately. The first physical symptoms are usually nausea, vomiting, and bloody diarrhea. After an early feeling of slight discomfort, there is a sudden onset of extreme stomach pain, violent vomiting, intense thirst, and cyanosis of the extremities. Jaundice of the eyes and skin can also occur if the liver is badly affected. The patient remains conscious almost to the end, with only brief intervals of unconsciousness occurring between long lucid periods before lapsing into a coma followed by death.
Antidotes and Treatments: There are no known antidotes for Amanita poisoning; however, victims have survived after receiving liver transplants.

Fossil Find Challenges Theories on T. Rex
From The New York Times:
Paleontologists said Thursday that they had discovered what amounted to a miniature prototype of Tyrannosaurus rex, complete with the oversize head, powerful jaws, long legs — and, as every schoolchild knows, puny arms — that were hallmarks of the king of the dinosaurs.
But this scaled-down version, which was about nine feet long and weighed only 150 pounds, lived 125 million years ago, about 35 million years before giant Tyrannosaurs roamed the earth. So the discovery calls into question theories about the evolution of T. rex, which was about five times longer and almost 100 times heavier.

British Skeleton Suggests Ancient Murder Mystery
From Live Science:
A skeleton found at an ancient Roman site in Britain has researchers wondering if they've stumbled on a murder mystery.
Excavations at the buried town of Venta Icenorum at Caistor St. Edmund in Norfolk, England, found what, for now, archaeologists are terming a "highly unusual" setup.
"This is an abnormal burial," said archaeologist Will Bowden of the University of Nottingham. "The body, which is probably male, was placed in a shallow pit on its side, as opposed to being laid out properly. This is not the care Romans normally accorded to their dead. It could be that the person was murdered or executed, although this is still a matter of speculation."
The skeleton has been removed for further investigation.
