Drug resistance is an all-too-common occurrence in cancer treatment. Now, working with physicians at Chaim Sheba Medical Center, the Weizmann Institute of Science’s Prof. Yossi Yarden has identified a three-drug combo that fends off drug resistance in lung cancer. This is particularly promising, as two of the medications are already in use.
Astronomers using ALMA studied a cataclysmic stellar explosion known as a gamma-ray burst, or GRB, and found its enduring “afterglow.” The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted thousands of times longer than expected. These observations provide fresh insights into the physics of GRBs, one of the universe’s most energetic explosions.
A small population of brain cells called "mossy cells" deep in a memory-making region of the brain controls the production of new neurons and may have a role in common brain disorders, according to a study from scientists at the University of North Carolina School of Medicine.
Scientists at Sanford Burnham Prebys Medical Discovery Institute (SBP), in collaboration with the Fondazione Santa Lucia IRCCS in Rome, have discovered a new disease-specific role of FAP cells in muscle wasting and scarring, indicating a potential new avenue for treating motor neuron diseases.
Mice fed a fattening diet develop new liver circadian rhythms that impact the way fat is accumulated and simultaneously burned. The team found that as liver fat production increases, surprisingly, so does the body’s ability to burn fat. These opposing physiological processes reach their peak activity each day around 5 p.m., illustrating an unexpected connection between overeating, circadian rhythms, and fat accumulation in the liver.
Mind-body therapies – biofeedback, mindfulness, yoga, and hypnosis – provide a promising approach to the very common problem of anxiety in adolescents, according to a review in the March issue of The Nurse Practitioner. The journal is published in the Lippincott portfolio by Wolters Kluwer.
In the forest canopies of Panama's Barro Colorado Island, treetops are warming faster than air temperature. That could mean major consequences for the health of the forest and the species that call it home.
Patients taking opioids for at least three months before spinal fusion surgery in the lower spine are much more likely to continue taking opioids one year after surgery, reports a study in Spine. The journal is published in the Lippincott portfolio by Wolters Kluwer.
Quantum computers work in a fundamentally different way than classical computers. Computer scientists need to start from scratch when creating algorithms for them to run. Three teams from the Department of Energy’s laboratories are developing the foundations for new computer languages and programs.
After 10 years of research, a Rutgers-led team of scientists has identified two molecules that protect nerve cells after a traumatic brain injury and could lead to new drug treatments. The molecules promote full recovery after traumatic brain injury (TBI) in mice, according to the study published online in Neurobiology of Disease.
For more than 30 years, board-certified dermatologists have been providing free skin cancer screenings in their communities through the AAD’s SPOTme® program — and research published today highlights the value of that program.
As adults age, they all experience a natural loss of muscle mass and function. A new study finds that as the loss of muscle and function in the throat occurs it becomes more difficult for efficient constriction to occur while swallowing – which leads to an increased chance of food and liquids being left over in the throat.
Nobody knows exactly what happens at the eye of the storm. But biologists have published a first-of-its-kind look at the physical characteristics of lizards that seem to make the difference between life and death in a hurricane, as reported on July 25 in the journal Nature. Hint: long, strong back legs do not help like you think they might.
Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered an earlier unknown discontinuous magnetoelastic transition in a rare-earth intermetallic. The mechanism of the material’s changing magnetic state is so unusual, it provides new possibilities for discovery of similar materials.
Parkinsonism – slowed movement, muscle rigidity and tremor – is a classic set of neurological symptoms most often seen in patients with Parkinson’s disease. Because neuron loss in the substantia nigra – a region of the brain associated with motor planning – is the hallmark characteristic of Parkinson’s disease, parkinsonism has long been thought to originate there. However, parkinsonism can occur in patients who have other conditions that leave the substantia nigra intact, making the true source of the suite of symptoms a mystery.
Finding could lead to targeted therapies for chronic condition
Patients who undergo coronary artery bypass grafting (CABG)—the most common heart surgery performed—may live longer and experience fewer complications when under the care of a highly focused surgical team that uses simplified and standardized approaches.
In a paper published online this spring in the journal Nature Photonics, scientists at the University of Washington report that a prototype semiconductor thin-film has performed even better than today’s best solar cell materials at emitting light.
Two units of plasma given in a medical helicopter on the way to the hospital could increase the odds of traumatically injured patients with severe bleeding surviving by 10 percent, according to the results of a national clinical trial.
People who feel faint, dizzy or lightheaded when standing up may be experiencing a sudden drop in blood pressure called orthostatic hypotension. Now a new study says middle-aged people who experience such a drop may have a greater risk of developing dementia or stroke decades later. The study is published in the July 25, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
