The same sources thought to inflict oxidative stress on cells—pollution, diesel exhaust, smoking and obesity—also are associated with shorter telomeres, the protective tips on the ends of the chromosomal shoelace. A new study from the University of Pittsburgh, published in Molecular Cell, provides the first smoking gun evidence that oxidative […]

Though much of the human genome has been sequenced and assembled, scientists have hit road blocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences. One of these regions, found in every cell, is the centromere. Researchers from the University of Rochester, along with their colleagues […]

These days, scientists can collect a few skin or blood cells, wipe out their identities, and reprogram them to become virtually any other kind of cell in the human body, from neurons to heart cells.   The journey from skin cell to another type of functional cell involves converting them into induced pluripotent […]

Obesity is a growing problem among toddlers, children and adolescents in the United States. Gaining weight and fat mass rapidly during the first six months of life is one risk factor that can lead to obesity in children.

After six years of work, researchers from Denmark and abroad have succeeded in uncovering genes which play an important role in the development […]

Cells missing a certain protein on their surface can’t move normally, UConn researchers reported in Science Signaling. The research could give insight into how cells move and repair wounds in normal tissue, as well as how cancer spreads through the body. Cells are the body’s workers, and they often need to […]

A molecule that helps blood clot may also play a role in multiple sclerosis relapses, researchers reported in the journal PNAS. The new research may help answer the mystery of why remissions happen, as well as find early markers of the disease. The research also shows a new way to […]

How do bones heal, and how could they heal better? The answer to these questions may lie in a newly discovered population of “messenger” cells, according to an USC Stem Cell study published in the journal eLife. “With nearly half a million patients in the U.S experiencing failed bone repair every […]

Although much of the human genome has been sequenced and assembled, scientists have hit roadblocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences, including the centromere. Now, for the first time, researchers from the University of Connecticut and University of Rochester have sequenced all the […]

Scientists from Trinity have discovered a potential new target for regulating inflammation, which drives a range of diseases including diabetes, cancer and Alzheimer’s.  The potential target is an ancient immune protein – SARM – that has been conserved throughout evolution and thus is very similar in humans, other mammals, flies and worms. […]

The discovery of a new way to target and treat the leading genetic contributor to Parkinson's may open the way for a potential new clinical treatment. Researchers from Oxford’s Department of Physiology, Anatomy and Genetics (DPAG) have identified how the dysfunction of a key protein, LRRK2, causes the neurons affected […]

Researchers have developed a method that could drastically accelerate the search for new drugs to treat mental health disorders such as schizophrenia. Mental health disorders are the leading cause of disability worldwide, accounting for 31% of total years lived with disability. While our understanding of the biology behind these disorders […]

Most human cells have 23 pairs of chromosomes. Any deviation from this number can be fatal for cells, and several genetic disorders, such as Down syndrome, are caused by abnormal numbers of chromosomes. For decades, biologists have also known that cancer cells often have too few or too many copies […]

Children with their first or early adult set of teeth that stick out have an increased chance of damaging them, but the risk can be easily reduced without being prohibitively costly. A study undertaken at the University of Adelaide of more than 50,000 children aged under 19 years published in […]

UW Medicine researchers are recruiting pregnant women to study whether prenatal marijuana use – in the absence of alcohol, tobacco, and any illicit drug consumption – affects their infants’ brain development, cognitive and motor development, medical health, and social behavior.
