A surprise discovery that overturns decades of thinking about how the body fixes proteins that come unraveled greatly expands opportunities for therapies to prevent diseases such as Alzheimer’s and Parkinson’s, which have been linked to the accumulation of improperly folded proteins in the brain.
The seemingly miraculous power of babies’ hearts to repair themselves after being...
In acute asthma, various triggers, including viral illnesses and aeroallergens, can cause...
Using ultrasound to deliver power wirelessly, researchers are working on a new generation...
The discovery of a cellular snooze button has allowed a team of scientists to potentially improve biofuel production and offer insight on the early stages of cancer.
A team of scientists and engineers developed a new surface coating for medical devices using materials already approved by the Food and Drug Administration (FDA). The coating repelled blood from more than 20 medically relevant substrates the team tested.
Just look into the light: not quite, but researchers have used light to erase specific memories in mice, and proved a basic theory of how different parts of the brain work together to retrieve episodic memories.
A team of engineers has successfully developed a three-dimensional-printed device, which mimics the operation of the liver to remove dangerous toxins from the blood.
In a new study that should make it easier to develop stem-cell-based therapies, a team of researchers has identified three physical characteristics of MSCs that can distinguish them from other immature cells found in the bone marrow.
A project to develop a barcoding and tracking system for tissue stem cells has revealed previously unrecognized features of normal blood production: New data suggests, surprisingly, that the billions of blood cells that we produce each day are made not by blood stem cells, but rather their less pluripotent descendants, called progenitor cells.
The largest genome-wide association study (GWAS) to date, involving more than 300 institutions and more than 250,000 subjects, roughly doubles the number of known gene regions influencing height to more than 400.
Previously undiscovered secrets of how human cells interact with a bacterium which causes a serious human disease have been revealed in new research by microbiologists.
Scientists have moved a step closer to improving medical science through research involving muscle manipulation of fruit flies. They discovered in the flight muscles of Drosophila a new regulator of a process called alternative splicing.
What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans? A great deal when his DNA profile is one of the "earliest diverged"– oldest in genetic terms– found to-date in a region where modern humans are believed to have originated roughly 200,000 years ago.
The Obama administration is tightening oversight of high-stakes scientific research involving dangerous germs that could raise biosecurity concerns, imposing new safety rules on universities and other institutions where such work is done.
Doctors at three leading research institutions and the American Diabetes Association report that treating patients with prediabetes as if they had diabetes could help prevent or delay the most severe complications associated with this chronic disease.
A $3.7 million grant will allow Purdue University researchers to study how blueberries reduce bone loss in postmenopausal women. The project begins Sept. 30 under a five-year grant from the National Institutes of Health's National Center for Complementary and Alternative Medicine.
A person’s face is the first thing that others see, and much remains unknown about how it forms— or malforms— during early development. New research has begun to unwind these mysteries.
While previous studies of the brain suggest that processing of objects and place occur in very different locations, a research team has found that they are closely related.
A simple point-of-care testing device for anemia could provide more rapid diagnosis of the common blood disorder and allow inexpensive at-home self-monitoring of persons with chronic forms of the disease.
Researchers have used brain scans to predict how young children learn to read, giving clinicians a possible tool to spot children with dyslexia and other reading difficulties before they experience reading challenges.
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in the blood—often too fast for antibiotics to help. A new device inspired by the human spleen may radically transform the way doctors treat sepsis.
Researchers have discovered how two genes– Period and Cryptochrome– keep the circadian clocks in all human cells in time and in proper rhythm with the 24-hour day, as well as the seasons.
Researchers have shown that a stressed cell recognizes the buildup of misfolded proteins and responds by reshuffling its workload, much like a stressed out employee might temporarily move papers from an overflowing inbox into a junk drawer.
Researchers have discovered that a known quality control mechanism in human, animal and plant cells is active against viruses. They think it might represent one of the oldest defense mechanisms against viruses in evolutionary history.
The race to stamp out West Africa’s Ebola epidemic is not just about saving lives. It’s also about stemming an assault on society that could include food shortages and mass migration, morphing from a medical emergency into a broad humanitarian crisis.
Numerous studies have linked social interaction to improved health and survival in humans, and new research confirms that the same is true for baboons.
Figuring out how blank slate stem cells decide which kind of cell they want to be when they grow up— a muscle cell, a bone cell, a neuron— has been no small task for science. Now, a team of researchers has added a new wrinkle to the cell differentiation equation.
Life can be so intricate and novel that even a single cell can pack a few surprises, according to a new study. The pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate, the study says.
