Only 8.2 percent of human DNA is likely to be doing something important – is “functional”– say researchers. This figure is very different from one given in 2012, when some scientists stated that 80 percent of our genome has some biochemical function.
By using brightly hued dyes, George Mason University (GMU) researchers discovered an innovative...
Parents, turn off the television when your children are with you. And when you do let them watch...
When a person experiences a devastating loss or tragic event, why does every detail seem burned...
A nine-day quarantine imposed on parts of a northern Chinese city where a man there died of bubonic plague has been lifted, China's official news agency reported Thursday.
Health officials say that the head of the government lab which potentially exposed workers to live anthrax has resigned. Michael Farrell was head of the Centers for Disease Control and Prevention lab since 2009.
In a new study, a team of researchers has found evidence for a factor that contributes to adults’ language difficulties: When learning certain elements of language, adults’ more highly developed cognitive skills actually get in the way.
Scientists have developed a scalable, next-generation platelet bioreactor to generate fully functional human platelets in vitro. The work might help address blood transfusion needs worldwide.
People with Type 2 diabetes have an excess of a protein called islet amyloid polypeptide, or IAPP, and the accumulation of this protein is linked to the loss of insulin-producing pancreatic beta cells. Now, a team of researchers may have found a solution in autophagy, a process that clears damaged and toxic proteins from cell.
Scientists have linked more than 100 spots in our DNA to the risk of developing schizophrenia, casting light on the mystery of what makes the disease tick. Such work could eventually point to new treatments, although they are many years away.
A new study in mice reveals that mesenchymal stem cells (MSCs) help rejuvenate skeletal muscle after resistance exercise. By injecting MSCs into mouse leg muscles prior to several bouts of eccentric exercise, researchers were able to increase the rate of repair and enhance the growth and strength of those muscles in the exercising mice.
The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.
Mixed genes appear to drive hybrid birds to select more difficult routes than their parent species, according to new research from University of British Columbia zoologists. the researchers harnessed a flock of B.C. Swainson’s thrushes with tiny geolocating backpacks to map their routes as they migrated south through the U.S. to Central and South America.
Vitamin D-deficient individuals are twice as likely to be diagnosed with schizophrenia as people who have sufficient levels of the vitamin, according to a new study.
In two months, the first of many new Parkinson’s disease (PD) patients will receive a fetal cell transplant. The transplant will mark the end of a voluntary moratorium by many Western nations after complications arose a decade ago. This, combined with news that embryonic stem (ES) cell PD therapies may also near prime-time, made Parkinson’s a big topic at the recent International Society for Stem Cell Research (ISSCR) meeting.
In an analysis of metabolites used by the body to make fuel in normal and cancerous cells in human kidney tissue, a research team identified an enzyme that is key to applying the brakes on tumor growth.
Researchers have developed a powerful new single-cell technique to help investigate how the environment affects our development and the traits we inherit from our parents. The technique can be used to map all of the 'epigenetic marks' on the DNA within a single cell.
Researchers have successfully used a new and potentially safer method to stimulate ovulation in women undergoing IVF treatment. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature.
Most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches, researchers have found. Heritability also outweighed other risk factors in this largest study of its kind to date.
A research team has demonstrated that the viral reservoir of HIV-1 infection is established strikingly early after intrarectal simian immunodeficiency virus (SIV) infection of rhesus monkeys and before detectable viremia.
New research provides an intriguing glimpse into the processes that establish connections between nerve cells in the brain. These synapses allow nerve cells to transmit and process information involved in thinking and moving the body.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.” The advance could potentially lead to powerful new ways of combating malaria and other insect-borne diseases.
Scientists at the Salk Institute have identified a gene responsible for stopping the movement of cancer from the lungs to other parts of the body, indicating a new way to fight one of the world's deadliest cancers. By identifying the cause of this metastasis—which often happens quickly in lung cancer and results in a bleak survival rate—Salk scientists are able to explain why some tumors are more prone to spreading than others.
Economists at the University’s Centre for Competitive Advantage in the Global Economy (CAGE) have looked at why certain countries top the world happiness rankings. In particular they have found the closer a nation is to the genetic makeup of Denmark, the happier that country is. The research could help to solve the puzzle of why a country like Denmark so regularly tops the world happiness rankings.
It is something of an eternal question: Can we slow or even reverse the aging process? Even though genetic manipulations can, in fact, alter some cellular dynamics, little is known about the mechanisms of the aging process in living organisms. Now scientists from the Florida campus of The Scripps Research Institute have found in animal models that a single gene plays a surprising role in aging that can be detected early on in development.
Researchers have identified a group of cells in the brain that they say plays an important role in the abnormal neuron development in Down syndrome. After developing a new model for studying the syndrome using patient-derived stem cells, the scientists also found that applying an inexpensive antibiotic to the cells appears to correct many abnormalities in the interaction between the cells and developing neurons.
A daily low-dose aspirin is widely prescribed for the prevention of cardiovascular disease. Now, a new study suggests that common genetic variation may modify the cardiovascular benefit of aspirin.
Researchers have uncovered a genetic vulnerability of cancer cells that express telomerase— an enzyme that drives their unchecked growth— and showed that telomerase-expressing cells depend upon a gene named p21 for their survival.
Many promising clinical trials were highlighted at the annual meeting of the International Society of Stem Cell Research (ISSCR). One set of trials highlighted were monogenic gene therapy trials and cancer immunotherapy trials. Also discussed were trials for Parkinson’s disease, Multiple Sclerosis, and potential future trials involving cochlear stem cells.
