Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.

The presence of chronic inflammation in benign prostate tissue was associated with high-grade, or aggressive, prostate cancer, and this association was found even in those with low prostate-specific antigen (PSA) levels, according to a new study.
Researchers have discovered interacting proteins on the surface of the sperm and the egg essential to begin mammalian life. These proteins offer new paths towards improved fertility treatments and the development of new contraceptives.
Scientists have created a new model of memory that explains how neurons retain select memories a few hours after an event. This new framework provides a more complete picture of how memory works, which can inform research into disorders liked Parkinson's and Alzheimer's.
Researchers used an MRI-based method to identify and confirm the presence of brown adipose tissue in a living adult, which could prove to be an essential step towards a new wave of therapies to aid the fight against diabetes and obesity.
The Ebola virus that has killed scores of people in Guinea this year is a new strain - evidence that the disease did not spread there from outbreaks in some other African nations, scientists report.
Teenagers who have suffered a traumatic brain injury such as a concussion are at “significantly greater odds” of attempting suicide, being bullied and engaging in a variety of high risk behaviors, a new study has found.
Cases of diabetes and pre-diabetes in the United States have nearly doubled since 1988, suggests new research, with obesity apparently to blame for the surge.
Psychologists have presented the first study to reveal that our brains rely on an active suppression mechanism to avoid being distracted by salient irrelevant information when we want to focus on a particular item or task.
It’s long been known that certain strains of human papillomavirus (HPV) cause cancer. Now, researchers have determined a new way that HPV might spark cancer development– by disrupting the human DNA sequence with repeating loops when the virus is inserted into host-cell DNA as it replicates.
Using just a single drop of blood, a team of UW-Madison researchers has developed a faster, cheaper and more accurate tool for diagnosing even mild cases of asthma. This handheld technology—which takes advantage of a previously unknown correlation between asthmatic patients and the most abundant type of white blood cells in the body—means doctors could diagnose asthma even if their patients are not experiencing symptoms during their visit.
Young adults who used marijuana only recreationally showed significant abnormalities in two brain regions that are important in emotion and motivation. This is the first study to show casual use of marijuana is related to major brain changes.
Depression can hit young fathers hard- with symptoms increasing dramatically during some of the most important years of their children’s lives, a new study has found.
The first human volunteer will receive red blood cells cultured in the laboratory within the next three years, as part of a long-term research program funded by the Wellcome Trust.
If you follow cancer biology, then you’ve probably heard of ubiquitin before. In a recent paper researchers provided a structural rationale for how ubiquitin helps RIG-I do its job— and how that might help keep the immune system from getting out of hand.
A mumps outbreak in central Ohio has grown to more than 200 confirmed cases, public health officials said. A total of 212 cases of the contagious viral illness, with 132 of those linked to Ohio State University, have been reported.
A team of scientists published details of how a class of drugs called “HDACis” drive muscle-cell regeneration in the early stages of dystrophic muscles, but fail to work in late stages. The findings are key to furthering clinical development of HDACis for Duchenne muscular dystrophy (DMD), an incurable muscle-wasting disease.
Scientists at the University of Basel report first ever successful nose reconstruction surgery using cartilage grown in the laboratory. Cartilage cells were extracted from the patient’s nasal septum, multiplied and expanded onto a collagen membrane. The so-called engineered cartilage was then shaped according to the defect and implanted.
Synthetic collagen invented at Rice University may help wounds heal by directing the natural clotting of blood. The material, KOD, mimics natural collagen, a fibrous protein that binds cells together into organs and tissues. It could improve upon commercial sponges or therapies based on naturally derived porcine or bovine-derived collagen now used to aid healing during or after surgery.
Scientists are attempting to build a human heart with a 3-D printer. Ultimately, the goal is to create a new heart for a patient with their own cells that could be transplanted. It is an ambitious project to first, make a heart and then get it to work in a patient, and it could be years — perhaps decades — before a 3-D printed heart would ever be put in a person.
The more cups of coffee a person drank, the lower the risk for developing hepatocellular carcinoma (HCC), the most common type of liver cancer, according to new research.
When NASA sends an identical twin to the International Space Station next year, a Colorado State University researcher will be among just a few hand-picked scientists studying him and his brother to measure impacts of space travel on the human body.
An antimicrobial agent found in common household soaps, shampoos, and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection.
In a north London hospital, scientists are growing noses, ears and blood vessels in a bold attempt to make body parts in the laboratory. It's far from the only lab in the world that is pursuing the futuristic idea of growing organs for transplant. But the London work was showcased Tuesday as Mayor Boris Johnson announced a plan to attract more labs to do cutting-edge health and science research in the area.
A U.S. jury ordered Japanese drugmaker Takeda Pharmaceutical Co. and its U.S. counterpart, Eli Lilly and Co., to pay $9 billion in punitive damages over a diabetes medicine linked to cancer. The drug companies said Tuesday they will "vigorously challenge" the decision. The U.S District Court in western Louisiana ordered a $6 billion penalty for Takeda and $3 billion for its business partner and co-defendant Eli Lilly.
Researchers have devised a way to quickly bring to the clinic the technique of using blood samples to diagnose many types of solid cancers, or to monitor the amount of cancer in a patient’s body and responses to treatment.
