Scientists have long speculated that mosaicism plays a bigger role in the transmission of rare disease mutations than is currently known. Now, a study sheds new light on the frequency of mosaicism in genomic disorders and its influence on recurrence risk.
Research at New York University is paving the way for a breakthrough that may prevent brain...
A new study has found that a peptide called caerulein can convert existing cells in the pancreas...
Much of the liver’s metabolic function is governed by circadian rhythms—our own body clock—and...
The Food and Drug Administration says it will begin regulating laboratory-developed tests, a growing class of medical diagnostics that have never before been subject to federal oversight.
The brains of children with autism are relatively inflexible at switching from rest to task performance, according to a new study. Instead of changing to accommodate a job, connectivity in key brain networks of autistic children looks similar to connectivity in the resting brain. And the greater this inflexibility, the more severe the child’s manifestations of repetitive and restrictive behaviors that characterize autism, the study found.
Young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases, according to research from the Brown School at Washington University in St. Louis.
FEI's new phase plate is a stable, durable solution to increase the contrast of sensitive biological samples and is available on most TEM platforms from FEI.
The Confocal iPad app from Leica Microsystems introduces researchers and students of the life sciences to confocal methods and technologies.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on gold nanoparticles' promise in drug delivery. Our second story examines the work being done to decipher the wheat genome and the implications of this work.
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. Scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.
Biologists are studying retinal regeneration in zebrafish to find ways to combat human eye diseases. The small, minnow-like fish have eyes that develop in a way very similar to humans, but have the ability to regenerate retinal cells following an injury.
Researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that could give doctors a simple blood test to reliably predict a person’s risk of attempting suicide.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.
When cancers spread into the bloodstream, they often take on different characteristics, requiring different therapies. But it is hard to find these rare blood-borne cells. So, relapsed patients often do not get personalized care. Now, researchers have come up with a solution that zeros in on elusive circulating tumor cells (CTCs).
Researchers have discovered that stem cells inside the soft tissues of the tooth come from an unexpected source, namely nerves. These findings contribute to brand new knowledge of how teeth are formed, how they grow and how they are able to self-repair.
The Titan Halo transmission electron microscope (TEM) from FEI provides high-quality optical performance with enhanced flexibility for multi-scale applications in life and biomaterials sciences.
A new research project shows that many adolescents suffer from knee pain for several years. The pain impacts both sporting activities and quality of life.
Two recent studies— one human, one mouse— have found cloning creates better pluripotent stem cells than the Nobel Prize-winning induced pluripotent stem cell (iPSC) method. A third study also came out supporting the conclusions.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study by Tulane University School of Medicine cancer researchers.
The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.
One strategy for developing a highly effective HIV vaccine is to learn how some HIV-infected people naturally develop antibodies that can stop a high percentage of global HIV strains from infecting human cells in the laboratory. These so-called broadly neutralizing antibodies (bNAbs) develop too late to help infected people overcome the virus.
A multi-institutional team of researchers has developed a new nanoscale agent for imaging the gastrointestinal (GI) tract. This safe, noninvasive method for assessing the function and properties of the GI tract in real time could lead to better diagnosis and treatment of gut diseases.
In a new study, biophysicists describe– in minute detail- how actin filaments are stabilized at one of their ends to form a basic muscle structure called the sarcomere.
Trillions of bacteria live in each person’s digestive tract, but their role in human health is not well understood. To help shed light on the role of these bacteria, a team of researchers recently tracked fluctuations in the bacterial populations of two research subjects over a full year.
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 way to reveal where proteins touch each other, possibly leading to new treatments for cancer, arthritis, heart disease, and even lung disease.
Fragile X syndrome (FXS) is a genetic disorder that causes obsessive-compulsive and repetitive behaviors, and other behaviors on the autistic spectrum, as well as cognitive deficits. It is the most common inherited cause of mental impairment and the most common cause of autism. Now biomedical scientists at the University of California, Riverside have published a study that sheds light on the cause of autistic behaviors in FXS.
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.
