Earliest Human Species Possibly Found in Ethiopia

An ancient jawbone fragment is the oldest human fossil discovered yet, a bone potentially from a new species that reveals the human family may have arose a half million years earlier than previously thought, researchers say. This find also sheds light on the kind of landscape where humans first originated, scientists added. Although modern humans…

Genetically speaking, mammals are more like their fathers

You might resemble or act more like your mother, but a novel research study from UNC School of Medicine researchers reveals that mammals are genetically more like their dads. Specifically, the research shows that although we inherit equal amounts of genetic mutations from our parents -- the mutations that make us who we are and…

‘Nightmare Bacteria’ Require Old and New Weapons

"Superbug" bacteria that are resistant to antibiotics have the potential to create a nightmare scenario for modern medicine, but experts are hopeful that doctors will be able to slow the spread of these scary infections, by both traditional means and new innovations. Recently, a Los Angeles hospital announced that more than 100 patients treated there…

DNA evidence shows surprise cultural connections between Britain and Europe 8,000 years ago

The ancient British were not cut off from Europeans on an isolated island 8,000 years ago as previously thought, new research suggests. Researchers found evidence for a variety of wheat at a submerged archaeological site off the south coast of England, 2,000 years before the introduction of farming in the UK. The team argue that…

‘Big Brain’ Gene Found in Humans, Not Chimps

A single gene may have paved the way for the rise of human intelligence by dramatically increasing the number of brain cells found in a key brain region. This gene seems to be uniquely human: It is found in modern-day humans, Neanderthals and another branch of extinct humans called Denisovans, but not in chimpanzees. By…

Kenyan fossils show evolution of hippos

A French-Kenyan research team has just described a new fossil ancestor of today's hippo family. This discovery bridges a gap in the fossil record separating these animals from their closest modern-day cousins, the cetaceans. It also shows that some 35 million years ago, the ancestors of hippos were among the first large mammals to colonize…

Scientists announce anti-HIV agent so powerful it can work in a vaccine

In a remarkable new advance against the virus that causes AIDS, scientists from the Jupiter, Florida campus of The Scripps Research Institute (TSRI) have announced the creation of a novel drug candidate that is so potent and universally effective, it might work as part of an unconventional vaccine. The research, which involved scientists from more than…

New antibiotic holds promise against antibiotic-resistant infections

Estimates of deaths from methicillin-resistant Staphylococcus aureus (MRSA) in the United States range upwards of 19,000 annually. Around 1960, when Staphylococcus aureus developed resistance to first-generation penicillin, methicillin and other second-generation beta-lactam antibiotics were adopted to fight the illness. The modern variants of the bacterium have developed resistance to the four drugs now used to…

‘Shadow biosphere’ might be hiding strange life right under our noses

If we came across alien life, would we even know it was alive? That was a central question posed at a session here yesterday at the annual meeting of AAAS (which publishes Science). All known life on Earth fits a particular mold, but life from other planets might break free from that mold, making it…

Warming pushes Western U.S. toward driest period in 1,000 years: Unprecedented risk of drought in 21st century

During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions "driven primarily" by human-induced global warming, a new study predicts. The research says the drying would surpass in severity any of the decades-long "megadroughts"…
