A new study led by Harvard School of Public Health (HSPH) researchers identifies a key molecular mechanism behind the health benefits of dietary restriction, or reduced food intake without malnutrition. Also known as calorie restriction, dietary restriction is best known for its ability to slow aging in laboratory animals.
Forgetfulness, it turns out, is all in the head. Scientists have shown that fading memory and clouding judgment, the type that comes with advancing age, show up as lost and altered connections between neurons in the brain. But new experiments suggest an existing drug, known as riluzole and already on the market as a treatment for ALS, may help prevent these changes.
Scientists have created primordial germ cells – cells that will go on to become egg and sperm – using human embryonic stem cells.
A team of researchers has made big strides toward a future in which the predominant chemical factories of the world are colonies of genetically engineered bacteria.
Culture influences the link between emotion and depression, according to new research into depression in developing countries.
An international research team, including four Simon Fraser University scientists, has identified the "mutational landscape" of intrahepatic cholangiocarcinoma (ICC), a rare, highly fatal form of liver cancer that disproportionately affects people in Asian countries.
UT Southwestern Medical Center cancer researchers have demonstrated that whole-genome sequencing can be used to identify patients' risk for hereditary cancer, which can potentially lead to improvements in cancer prevention, diagnosis, and care.
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.
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.
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.
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.
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.
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.
