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…

‘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…
