Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve detection sensitivity to chemicals in explosives or drugs.
Increasing healthy brown fat might help weight management and reduce symptoms of diabetes. Columbia Engineers have developed a simple, innovative method to directly convert white fat to brown fat outside the body and then reimplant it in a patient. The technique uses fat-grafting procedures commonly performed by plastic surgeons, in which fat is harvested from under the skin and then retransplanted into the same patient for cosmetic or reconstructive purposes.
Plants can’t do without phosphorus. But there is often a ‘withdrawal limit’ on how much phosphorus they can get from the soil. A new study looks at how liming, soil management history, and enzymes relate to plants' access to phosphorus.
On World Lung Cancer Day, the American Thoracic Society, alongside members of the Forum of International Respiratory Societies (FIRS) commemorate and support those impacted by lung cancer. FIRS continues to support the grassroots efforts of the lung cancer community to raise awareness about lung cancer and its global impact, creating an educational movement around the world of understanding about lung cancer risks as well as the importance of early treatment.
In patients with chronic kidney disease, medical nutrition therapy can slow the progression and significantly reduce healthcare costs.But 90 percent of non-dialysis kidney disease patients never meet with a dietitian, according to a report in the Journal of the Academy of Nutrition and Dietetics.
Adult survivors of childhood cancer should be screened for financial problems that might cause them to delay or skip medical care or to suffer psychological distress. The recommendation from St. Jude Children’s Research Hospital researchers followed an analysis that found 65 percent of survivors reported financial challenges related to their childhood cancer diagnoses. More than half of survivors (51.1 percent) indicated they worried about paying for care, and 33 percent said finances kept them from seeking medical care.
Through a combination of reducing noise and adjusting the times for noisy activities, the neurosurgical ICU at North Shore University Hospital in New York reduced noise levels and maintained quiet times, according to a study published in Critical Care Nurse.

If people cannot adapt to future climate temperatures, deaths caused by severe heatwaves will increase dramatically in tropical and subtropical regions, followed closely by Australia, Europe and the United States, a global new Monash–led study shows.
Researchers at Wake Forest Baptist Medical Center have shown that gene expression analysis of blood samples taken from the recipients of transplanted kidneys can be used to better understand the mechanisms that promote repair and regeneration of the transplanted organs.
Mothers of critically ill infants may not receive necessary breastfeeding support, because their babies may be taken directly to a newborn intensive care unit or to surgery. Lactation expert Dr. Diane Spatz, of Children’s Hospital of Philadelphia, presents an alternative model for healthcare providers to care for vulnerable hospitalized infants, separated from their mothers.
Wolters Kluwer Health announced today it will begin publishing The Journal of the Association of Nurses in AIDS Care from the Association of Nurses in AIDS Care (ANAC). Under the new partnership, Wolters Kluwer will publish the clinical and scientific journal in its Lippincott Portfolio beginning January 2019.
Birds create songs by moving muscles in their vocal organs to vibrate air passing through their tissues, and new research shows that these muscles act in concert to create sound. Scientists describe how zebra finches produce songs in this week’s Chaos: Using electromyographic signals, they tracked the activity of one muscle involved in creating sound, the syringealis ventralis. They then used the data from this muscle to create a synthetic zebra finch song.
The word sabbatical could conjure up all sorts of envy in non-academics who may hear the term and think only of “paid time off.” However, this “time away” is anything but “time off.”
Earthbound detectives rely on fingerprints to solve their cases; now astronomers can do the same, using “light-fingerprints” instead of skin grooves to uncover the mysteries of exoplanets.
Researchers at the Bloomberg~Kimmel Institute for Cancer Immunotherapy in the Johns Hopkins Kimmel Cancer Center discovered inhibiting a previously known protein could reduce tumor burdens and enhance the effectiveness of immunotherapy treatments.
Women’s brains are much more vulnerable than men’s to injury from repeated soccer heading, according to a new study by researchers at Albert Einstein College of Medicine, part of Montefiore. The study found that regions of damaged brain tissue were five times more extensive in female soccer players than in males, suggesting that sex-specific guidelines may be warranted for preventing soccer-related head injuries. The results were published online today in Radiology.
When recreational scallopers flocked to Florida's Crystal River region, native sea turtles turned tail. Researchers say that sudden behavioral disruption could mean trouble the turtles overall health.
Medical teams at the Vanderbilt Transplant Center (VTC) are leading the way in utilization of hepatitis C-exposed donors for heart transplantation.

Researchers at Columbia found that a gene associated with an autoimmune form of hair loss may be activated to boost cancer immunotherapy.
All living things use the genetic code to “translate” DNA-based genetic information into proteins. Precisely how the process of translation arose in the earliest stages of life on Earth has long been mysterious, but two theoretical biologists have now made a significant advance in this field.
A University at Buffalo psychologist has proposed in a newly published paper that humpback whales may use song for long-range sonar. It’s the singing whale, not the listening whale who is doing most of the analysis, according to Eduardo Mercado III. If he’s right, Mercado says his model should change the direction of how we study whales.
Researchers at UC Santa Cruz are addressing the issues of groundwater supply and water quality with an ongoing "managed aquifer recharge" program in the Pajaro Valley, where they have been implementing and studying groundwater recharge projects and evaluating methods to improve water quality as it infiltrates into the ground.
Researchers at the University of Illinois at Chicago have demonstrated that magnetic nanoparticles can be used to ferry chemotherapy drugs into the spinal cord to treat hard-to-reach spinal tumors in an animal model. The unique delivery system represents a novel way to target chemotherapy drugs to spinal cancer cells, which are hard to reach because the drugs must cross the blood-brain barrier.
A team of researchers led by cardiologists at UT Southwestern Medical Center has developed a new online tool to more accurately predict who among those ages 40-65 is at the highest risk of suffering a heart attack or stroke in the next 10 years.
Astronomers have made the first definitive detection of a radioactive molecule in interstellar space: a form, or isotopologue of aluminum monofluoride (26AlF). The new data – made with ALMA and the NOEMA radio telescopes – reveal that this radioactive isotopologue was ejected into space by the collision of two stars, a tremendously rare cosmic event that was witnessed on Earth as a “new star,” or nova, in the year 1670.
The dominant existing technology—silicon—is more than 90 percent of the way to its theoretical efficiency limit. More efficient technologies will be more expensive. ASU study finds the acceptable intersection of costs vs. efficiency.
Proponents of “terraforming” Mars to make it habitable propose releasing greenhouse gases from the planet’s surface such as carbon dioxide (CO2) to trap heat, warm the climate and ultimately increase the atmospheric pressure. The plausibility of achieving this with current technology is the focus of a new study sponsored by NASA just published in Nature Astronomy.
Seriously, does anyone really like peas? More importantly, should parents pressure kids to eat them anyway, and does it hurt or help the child?
A common class of drugs used to treat diabetes exerts a powerful check on macrophages by controlling the metabolic fuel they use to generate energy. Keeping macrophages from going overboard on the job may inhibit the onset of obesity and diabetes following tissue inflammation.
Johns Hopkins researchers report they have demonstrated in mouse tissue grown in the lab that the cell layer surrounding breast milk ducts reaches out to grab stray cancer cells to keep them from spreading through the body. The findings reveal that this cell layer, called the myoepithelium, is not a stationary barrier to cancer invasion, as scientists previously thought, but an active defense against breast cancer metastasis.
In a study published in the August issue of Diseases of the Colon & Rectum, investigators from the University of Alabama at Birmingham sought to answer this question. While it has been long recognized that heavy patients are at higher risk of complications after surgery, Dr. Wahl and his colleagues wanted to find out whether there was a difference whether a patient was merely pudgy or downright obese.
Nearly a third of older adults have received a prescription for an opioid pain medicine in the past two years, but a new poll shows many didn’t get enough counseling about the risks that come with them, how to reduce use, when to switch to a non-opioid, or what to do with leftovers. Nearly three-quarters support limits on how many opioids a doctor can prescribe at once.
What do patients really want? These are Important questions that doctors at the University of Vermont have tried to answer. In the August issue of Diseases of the Colon & Rectum, Dr. Wrenn and his colleagues surveyed 167 patients who had undergone a colorectal resection between 2009 and 2015.
Columbia University researchers report the use of SRS microscopy, a technique widely used in biomedical studies, to explore the mechanism behind dendrite growth in lithium batteries, the first team of material scientists to directly observe ion transport in electrolytes. They were able to see not only why lithium dendrites form but also how to inhibit their growth. Visualizing ion movement could help improve the performance of electrochemical devices, from batteries to fuel cells to sensors.
