What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans? A great deal when his DNA profile is one of the "earliest diverged"– oldest in genetic terms– found to-date in a region where modern humans are believed to have originated roughly 200,000 years ago.

A person’s face is the first thing that others see, and much remains unknown about how it forms— or malforms— during early development. New research has begun to unwind these mysteries.
While previous studies of the brain suggest that processing of objects and place occur in very different locations, a research team has found that they are closely related.
A simple point-of-care testing device for anemia could provide more rapid diagnosis of the common blood disorder and allow inexpensive at-home self-monitoring of persons with chronic forms of the disease.
Researchers have used brain scans to predict how young children learn to read, giving clinicians a possible tool to spot children with dyslexia and other reading difficulties before they experience reading challenges.
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in the blood—often too fast for antibiotics to help. A new device inspired by the human spleen may radically transform the way doctors treat sepsis.
Researchers have discovered how two genes– Period and Cryptochrome– keep the circadian clocks in all human cells in time and in proper rhythm with the 24-hour day, as well as the seasons.
Researchers have shown that a stressed cell recognizes the buildup of misfolded proteins and responds by reshuffling its workload, much like a stressed out employee might temporarily move papers from an overflowing inbox into a junk drawer.
Researchers have discovered that a known quality control mechanism in human, animal and plant cells is active against viruses. They think it might represent one of the oldest defense mechanisms against viruses in evolutionary history.
The race to stamp out West Africa’s Ebola epidemic is not just about saving lives. It’s also about stemming an assault on society that could include food shortages and mass migration, morphing from a medical emergency into a broad humanitarian crisis.
Numerous studies have linked social interaction to improved health and survival in humans, and new research confirms that the same is true for baboons.
Figuring out how blank slate stem cells decide which kind of cell they want to be when they grow up— a muscle cell, a bone cell, a neuron— has been no small task for science. Now, a team of researchers has added a new wrinkle to the cell differentiation equation.
Life can be so intricate and novel that even a single cell can pack a few surprises, according to a new study. The pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate, the study says.
A team of investigators has made a thought-provoking discovery about a type of cholesterol previously believed to be a "bad guy" in the development of heart disease and other conditions.
Were Albert Einstein and Leonardo da Vinci born brilliant or did they acquire their intelligence through effort? No one knows for sure, but telling people the latter– that hard work trumps genes– causes instant changes in the brain and may make them more willing to strive for success, indicates a new study.
The way in which some cells alter their behavior at the onset of osteoarthritis has been identified for the first time. Researchers found that changes in the rate at which molecules in joint cartilage called mRNA are created and destroyed are fundamental to causing this change in behavior.
Scientists have hailed recent demonstrations of chemical technologies for making animal tissues see-through, but a new study is the first to evaluate three such technologies side-by-side for use with engineered 3-D tissue cultures.
How does short-term memory happen at the molecular level? New research has identified a calcium sensor that helps strengthen the connections between brain cells.
Riken Center for Developmental Biology (CDB), the prominent Japan institute where Haruko Obokata was found to commit misconduct on stem cell papers, will be halved, according to a Riken representative.
When you accidentally touch a hot oven, you rapidly pull your hand away. Although scientists know the basic neural circuits involved in sensing and responding to such painful stimuli, they are still sorting out the molecular players. Now, researchers have made a surprising discovery about the role of a key molecule involved in pain.
There's a good chance that many of the suddenly trendy vegetables that foodies latch on to in the next decade will benefit from research at the University of Wisconsin-Madison.
Researchers report that cells taken from the nasal septum are able to adapt to the environment of the knee joint and can thus repair articular cartilage defects. Read more...
An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue– the bundles of cells that make movement in animals possible.
Researchers have developed algorithms to identify weak spots in tendons, muscles and bones prone to tearing or breaking. The technology one day may help pinpoint minor strains and tiny injuries in the body’s tissues long before bigger problems occur.
The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. The discovery points toward probiotic therapies for this so-far untreatable condition.
Older adults losing vision as they age are more likely to face an increased mortality risk, according to new research. The researchers analyzed data from the Salisbury Eye Evaluation study that tracked the vision health of 2,520 older adults, ages 65 to 84.
