UCLA researchers found that nearly all people diagnosed with uveal melanoma had a number of unmet psychological and health information needs, particularly during the first three months after their diagnoses. The study is the first prospective, longitudinal approach to examine supportive care needs among patients with this disease, and suggested more acute needs among people with uveal melanoma than people with other cancers.
Recent studies suggest that ketamine, a widely used anesthetic agent, could offer a wholly new approach to treating severe depression—producing an antidepressant response in hours rather than weeks. Two reviews of recent evidence on ketamine and related drugs for treating depression appear in the Harvard Review of Psychiatry, published by Wolters Kluwer.
Approximately one in four preschoolers in the US are overweight or obese, and poor nutrition in early childhood has enduring consequences to children’s cognitive functioning. Preschool, therefore, is a critical period for children to begin to make their own dietary decisions to develop life-long healthy eating habits. A new study published in the Journal of Nutrition Education and Behavior found that preschoolers who learned how to classify food as healthy or unhealthy were more likely to say they would choose healthy food as a snack.
A research collaboration between the University of Arkansas and Fayetteville High School suggests that students benefited more when using the same type of modeling software used by scientists than through other instructional techniques.
Larotrectinib, a highly selective TRK kinase inhibitor, shows rapid, potent, and durable efficacy in both adult and pediatric patients with solid tumors that harbor TRK fusions, regardless of tumor type or patient age, according to results from three clinical trials published in the New England Journal of Medicine. The landmark data support the foundation of precision oncology by creating a treatment option for a genetically defined cancer while continuing to validate the concept that comprehensive molecular profiling should be strongly considered in people of all ages with advanced solid tumors.
Drier summers and a decline in average snowpack over the past 40 years have severely hampered the establishment of two foundational tree species in subalpine regions of Colorado’s Front Range, suggesting that climate warming is already taking a toll on forest health in some areas of the southern Rocky Mountains.
To treat cardiovascular disease, surgery can remove blockages in large vessels in the heart or legs but is not possible in small vessels. To address this problem, researchers designed 3D-printed patches seeded with vessel-inducing endothelial cells. In a mouse model of hindlimb ischemia, the researchers identified specific patch patterns that induced growth of organized, tissue-saving blood vessels, demonstrating the potential for the novel technology to address this significant public health problem.
Researchers have developed a highly-targeted and non-invasive drug-release method that combines a nanoscale gold particle-containing polymer coating and near-infrared light. The technology could also be used for other applications, including the sealing of internal and external injuries, and as biodegradable scaffolds for growing transplant organs.
About 25 years ago, University of Florida scientist Nan-Yao Su set out to develop a bait to kill termites. He came up with Sentricon™ and found it worked better than any other termite-killing method to date. Now, scientists know more about why the bait works so efficiently and how to improve it to kill termite colonies faster.
In JCI Insight, researchers reported the results of a phase I, multi-institution clinical trial for an investigational treatment for melanoma and other cancers with mutations in the BRAF or RAS genes.

UCLA researchers used fluorescent colored proteins to trace how cardiomyocytes — cells in heart muscle that enable it to pump blood — are produced in mouse embryos. The findings could eventually lead to methods for regenerating heart tissue in human adults.
Three quarters of patients with a variety of advanced cancers occurring in different sites of the body responded to larotrectinib, a novel therapy that targets a specific genetic mutation. The oral treatment is based on the genetic traits of the tumor and not the organ where the cancer originated.
New research co-authored by Berkeley Haas Assoc. Prof. Clayton Critcher finds that adding the required "I approve this message" tagline to negative campaign ads makes them more credible.
There’s a cause of dementia that can sometimes be reversed, but it’s often not diagnosed because the symptoms are so similar to those of other disorders. Now researchers say a simple walking test may be able to accurately diagnose the disease, according to a study published the February 21, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Carbon monoxide can improve the effectiveness of antibiotics, making bacteria more sensitive to antibiotic medication, according to a study led by Georgia State University.
New University of Colorado Boulder-led research has established a causal link between climate warming and the localized extinction of a common Rocky Mountain flowering plant, a result that could serve as a herald of future population declines.
Eating fish at least once a week or eating fish one to three times per month in addition to taking daily fish oil supplements may be associated with a reduced risk of multiple sclerosis (MS), according to a preliminary study released today that will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018. These findings suggest that the omega-3 fatty acids found in fish may be associated with lowering the risk of developing MS.
In one sense, the digital divide between teenagers from different socio-economic backgrounds is narrowing: All increasingly have access to technologies such as smartphones and computers. But a new digital divide appears to be emerging over the types of experiences these teens have online, according to a University of California, Irvine researcher.
Many women may write off fatigue, body aches and even nausea as the result of stress, or as an indication that they need to slow down and rest. What they might not realize is that those subtle symptoms could indicate something much more distressing: heart disease or the possibility of a heart attack.
Much like other muscles, when the heart works during the normal daytime hours, it needs a period of rest to repair itself.

UNC and NC State scientists created an injectable gel-like scaffold that can hold combination chemo-immunotherapeutic drugs and deliver them locally to tumors in a sequential manner. The results in animal models suggest this approach could one day ramp up therapeutic benefits for cancer patients.
The idea of binding and reshaping a baby’s head may make today’s parents cringe, but for families in the Andes between 1100-1450, cranial modification was all the rage.
In the last eight years, the field of ancient DNA research has expanded from just one ancient human genome to more than 1,300. The latest 625 of those genomes debut Feb. 21 in two papers published simultaneously in Nature, including the largest study of ancient DNA to date.
Fueled by advances in analyzing DNA from the bones of ancient humans, scientists have dramatically expanded the number of samples studied – revealing vast and surprising migrations and genetic mixing of populations in our prehistoric past.
Menlo Park, Calif. —Scientists have turned the smallest possible bits of diamond and other super-hard specks into “molecular anvils” that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.
A team from The Scripps Research Institute (TSRI) has revealed that by crossing two species of flies, they can use what they learn from the proteome of the hybrid offspring to find new clues about how proteins interact with each other
Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach “learns” much more quickly and requires far fewer images.
An international team of researchers led by a Case Western Reserve University School of Medicine scientist has uncovered a novel mechanism in which a protein—neuregulin 3—controls how key neurotransmitters are released in the brain during schizophrenia. The protein is elevated in people with schizophrenia and other severe mental illnesses, but the study is the first to investigate how it causes such severe mental illness.
A new study suggests that diabetes-related nerve damage (peripheral neuropathy) may reduce the amount of energy stored by the Achilles tendon during walking. The tendon connects the back of the heel to the calf muscles. This reduction increases the energy required for locomotion (“cost of walking”).
Some scientists have hypothesized that tumor-promoting changes in cells during cancer development—particularly an epigenetic change involving DNA methylation—arise from rogue cells escaping a natural cell deterioration process called senescence. Now, researchers at the Johns Hopkins Kimmel Cancer Center demonstrated that instead, tumor-associated epigenetic states evolve erratically during early stages of tumor development, eventually selecting for a subset of genes that undergo the most changes during normal aging and in early tumor development.
In what is believed to be the largest pancreatic cancer genome-wide association study to date, researchers at the Johns Hopkins Kimmel Cancer Center and the National Cancer Institute, and collaborators from over 80 other institutions worldwide discovered changes to five new regions in the human genome that may increase the risk of pancreatic cancer.
Treating food allergies might be a simple matter of teaching the immune system a new trick, researchers at Duke Health have found. In a study using mice bred to have peanut allergies, the Duke researchers were able to reprogram the animals' immune systems using a nanoparticle delivery of molecules to the lymph nodes that switched off the life-threatening reactions to peanut exposures.
A team of artificial intelligence researchers developed a new deep-learning method to identify tumours in medical images.
First known material capable of emitting single photons at room temperature and telecom wavelengths.
For couples with decades of shared memories, a partner’s decline in the ability to communicate because of dementia is frightening and frustrating. Communication strategies they’ve used before simply don’t work anymore. By getting creative, an in-home intervention to support couples affected by dementia is showing that “practice does make perfect,” both for the caregiver and the care receiver or person with dementia, and can improve their communication behaviors in just 10 weeks.
A non-native grass species has been wreaking havoc in wetlands all over the U.S., impacting migratory birds' fueling stops. In response, researchers test the usefulness of reed canarygrass as a feed source for cows, with hopes of controlling the invasive species.
A new study led by the Center for Injury Research and Policy at Nationwide Children’s Hospital used data from a national survey to examine the effectiveness of state-level cellphone laws in decreasing teens’ use of cellphones while driving. The study, done in conjunction with researchers from West Virginia University and the University of Minnesota, and published today in Journal of Adolescent Health, looked at state-level cellphone laws and differences in both texting and hand-held cellphone conversations among teen drivers across four years.
