Latest analysis of prehistoric bones show there is no anatomical reason why a person born today could not develop the skeletal strength of a prehistoric forager or a modern orangutan. Findings support the idea that activity throughout life is the key to building bone strength and preventing osteoporosis risk in later years, say researchers.
A new instrument could someday build replacement human organs the way electronics are assembled today: with precise picking and placing of parts.
Genes are important, but diet may be even more important in determining the relative abundance of the hundreds of health-shaping bacterial species comprising an individual’s gut microbiota, according to UC San Francisco scientists whose latest mouse experiments to probe this nature-versus-nurture balance were published online in Cell Host and Microbe.
President Obama's pick for the position turned out to be controversial.
A young scientist from Harvard University and the Riken Institute, who claimed to make extraordinary stem cells from ordinary cells with acid, has failed to repeat her work.
Millions upon millions of medical records and test results. Countless DNA sequences. Hard drives stuffed with images of all kinds - pictures of cells, scans of body parts. It's all part of the deluge of information often known as "big data," an ever-growing stockpile of digital material that scientists hope will reveal insights about biology and lead to improvements in medical care.
A new study found that the brains of obese children literally light up differently when tasting sugar. This elevated sense of “food reward” could mean some children have brain circuitries that predispose them to crave more sugar throughout life.
In a triumph for cell biology, researchers have assembled the first high-resolution, 3-D maps of entire folded genomes and found a structural basis for gene regulation, a kind of “genomic origami” that allows the same genome to produce different types of cells.
It’s well known that chemotherapy helps fight cancer. It’s also known that it wreaks havoc on normal, healthy cells. Scientists are closer to discovering a possible way to boost healthy cell production in cancer patients as they receive chemotherapy.
Researchers believe they’re on track to solve the mystery of weight gain – and it has nothing to do with indulging in holiday eggnog. They discovered that a protein, Thy1, has a fundamental role in controlling whether a primitive cell decides to become a fat cell, making Thy1 a possible therapeutic target.
Researchers have found new evidence that explains how some aspects of our personality may affect our health and wellbeing, supporting long-observed associations between aspects of human character, physical health and longevity.
Doctors, nurses and others fighting Ebola through "tireless acts of courage and mercy" have been named Time's 2014 Person of the Year, the magazine announced Wednesday.
Researchers have devised a way to replace the knee’s protective lining, called the meniscus, using a personalized 3-D-printed implant, or scaffold, infused with human growth factors that prompt the body to regenerate the lining on its own.
Researchers have found that drinking alcohol to fall asleep interferes with sleep homeostasis, the body’s sleep-regulating mechanism.
Researchers have found evidence suggesting that the male hormone testosterone may actually be a contributing factor in the formation of colon cancer tumors.
While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains revealed.
One of the recurring themes of the 2014 Forbes Healthcare Summit was that smartphones and mobile apps would play a larger role in the industry. However, the safety and security of these platforms are being debated. Nanthealth’s CEO Dr. Patrick Soon-Shiong feels he may have a solution.
For the first time, scientists report the development of a stretchable “electronic skin” closely modeled after our own that can detect not just pressure, but also what direction it’s coming from.
The cognitive effects of poverty can be mitigated during middle school with a targeted intervention, according to new research.
Scientists have developed a mathematical theory–based on roundworm foraging that predicts how animals decide to switch from localized to very broad searching.
Authorities in an eastern district of Sierra Leone launched a two-week "lockdown" on Wednesday, hoping to halt the spread of Ebola after the area recorded seven confirmed cases in a day.
Nitrous oxide, or laughing gas, has shown early promise as a potential treatment for severe depression in patients whose symptoms don’t respond to standard therapies.
Brain cells called microglia chew up toxic substances and cell debris, calm inflammation and make nerve-cell-nurturing substances. New research shows that keeping them on the job may prevent neurodegeneration.
Whole genome sequencing of MRSA from a hospital in Asia has demonstrated patterns of transmission in a resource-limited setting, where formal screening procedures are not feasible.
Philanthropist and entrepreneur Paul G. Allen announced a commitment of $100 million to create the Allen Institute for Cell Science in Seattle. The Allen Institute for Cell Science will take a multidisciplinary, team science-driven approach to understanding a fundamental and yet elusive question in cell science.
