Investigators have discovered the genomic switches of a blood cell key to regulating the human immune system. The findings open the door to new research and development in drugs and personalized medicine to help those with autoimmune disorders such as inflammatory bowel disease or rheumatoid arthritis.
A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth. But what happened next? Life can exist without oxygen, but without plentiful nitrogen to build genes -- essential to viruses, bacteria and all other organisms -- life on the early Earth would have been scarce. The ability to use atmospheric nitrogen to support more widespread life was thought to have appeared roughly 2 billion years ago. Now research looking at some of the planet's oldest rocks finds evidence that 3.2 billion years ago, life was already pulling nitrogen out of the air and converting it into a form that could support larger communities.
Scientists have uncovered a marvel molecule that blocks a key driver of inflammatory diseases. The finding could meet a major unmet clinical need by inspiring new non-invasive treatments for arthritis, multiple sclerosis and Muckle-Wells syndrome, among a myriad of other inflammatory diseases.
Frequent menopausal vasomotor symptoms (VMS), including hot flashes and night sweats, lasted for more than seven years during the transition to menopause for more than half of the women in a large study and African-American women reported the longest total VMS duration, according to a new article.
Mindfulness meditation practices resulted in improved sleep quality for older adults with moderate sleep disturbance in a clinical trial comparing meditation to a more structured program focusing on changing poor sleep habits and establishing a bedtime routine, according to a new article.
Ovarian cancer is the deadliest of all cancers affecting the female reproductive system with very few effective treatments available. Prognosis is even worse among patients with certain subtypes of the disease. Now, researchers have identified a new therapeutic target in a particularly aggressive form of ovarian cancer, paving the way for what could be the first effective targeted therapy of its kind for the disease.
A research team has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.
Penguins apparently can't enjoy or even detect the savory taste of the fish they eat or the sweet taste of fruit. A new analysis of the genetic evidence suggests that the flightless, waddling birds have lost three of the five basic tastes over evolutionary time. For them, it appears, food comes in only two flavors: salty and sour.
A particular gastrointestinal disorder, which causes colic, or abdominal pain, in horses, is more prevalent in Lancashire compared with other nearby counties, according to researchers.
Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.
A microsurgical technique credited with revolutionizing treatment of men once thought to be infertile is now being performed.
Benefit principle taxes, such as a mileage tax, have the potential to replace fuel taxes and make up for falling revenues. But new research shows that, at best, only one in three Americans believe roads should be financed with benefit-based taxes.
Cancer researchers have identified a molecule they say is important to survival of anaplastic thyroid carcinoma (ATC) — a lethal tumor with no effective therapies. The molecule also seems to play a role in a wide range of cancers, they report.
For decades, theories on the genetic advantage of sexual reproduction had been put forward, but none had ever been proven in humans, until now. Researchers have just shown how humanity's predispositions to disease gradually decrease the more we mix our genetic material together. This discovery was finally made possible by the availability in recent years of repositories of biological samples and genetic data from different populations around the globe.
The importance of RNA editing in melanoma has been demonstrated by scientists. The study revealed that a lack of RNA editing, a process by which information inside RNA molecules is transformed, leads to tumor growth and progression through manipulation of proteins.
A new study in mice has shown that the DNA of bacteria that live in the body can pass a trait to offspring in a way similar to the parents' own DNA. According to the authors, the discovery means scientists need to consider a significant new factor -- the DNA of microbes passed from mother to child -- in their efforts to understand how genes influence illness and health.
A spit test may one day be able to diagnose autism according to new research. Scientists have published the first study showing that children with autism spectrum disorder have differences in protein levels in their saliva when compared to typically developing children.
Researchers have discovered a novel role for Mitofusin 2, and the findings may point to a new treatment for patients with diseases caused by loss of the mitochondrial protein.
While people in the early years of marriage have sex more frequently, and their sexual activity tapers off over time, a slight rebound occurs for those whose marriages endure longer than half a century, according to new research.
A new family of bacteria that are common in malaria mosquitoes has been described by researchers in a recent publication. Now, attempts are made to use these bacteria in the fight against malaria.
