The skull dates from around 55,000 years ago, fitting into the period when scientists had thought the migrants inhabited the area.
Populations of certain types of marine organisms known collectively as the ‘biofouling community’ – tiny creatures that attach themselves to ships’ hulls and rocks – may quadruple within decades, while others may see their numbers reduced by as much as 80 percent, if the world’s oceans continue to become more acidic, according to new research.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
Eerie fluorescent blue patches of water glimmering off Hong Kong's seashore are magnificent, disturbing and potentially toxic.
A miniscule cluster of estrogen-producing nerve cells in the mouse brain exerts highly specific effects on aggressive behavior in both males and females.

The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
Standards proposed by the Agriculture Department aim to reduce rates of salmonella and campylobacter, another pathogen that can cause symptoms similar to salmonella, in chicken parts, ground chicken and ground turkey. The standards would be voluntary but designed to pressure companies to take steps to reduce contamination.
Cambridge scientists have discovered a solution for controlling one of the world’s biggest environmental and ecological pests – the zebra mussel.
The death of 100 birds in the San Francisco Bay Area has baffled wildlife officials who say the feathers of the birds were coated with a mysterious substance that looks and feels like rubber cement.
Wildlife biologists tracking a tumor-causing virus first diagnosed in eastern wild turkeys five years ago have found the virus is far more widespread - but less deadly - than expected.
A mystery kidney disease is killing Sri Lankan farmers. The first cases surfaced some two decades ago in the country's North Central province, the main rice-producing area. Since then, the disease has killed up to an estimated 20,000 people on the Indian Ocean island nation.
The antibody response from an HIV vaccine trial in Thailand was made possible by a genetic trait carried over in humans from an ancient ancestry with monkeys and apes.
The highly contagious respiratory illness was declared eliminated in the U.S. in 2000, but health officials have seen a surge of measles infections in the country in recent years.
A federal report says genetic markers of Asian carp are still showing up in Chicago-area waterways.

A new 12-year U.S. study shows the most frequent involve drugs used to stimulate ovaries, but it suggests problems are rarely fatal.
Some children are more sensitive to their environments, for better and for worse. Now Duke University researchers have identified a gene variant that may serve as a marker for these children, who are among society’s most vulnerable.
