Hollow molecular structures known as COFs suffer from an inherent problem: It’s difficult to keep a network of COFs connected in harsh chemical environments. Now, a team at the Berkeley Lab has used a chemical process discovered decades ago to make the linkages between COFs much more sturdy, and to give the COFs new characteristics that could expand their applications.
Scientists at the Innovative Genomics Institute have concocted a transformative new way to harness the power of evolution. Today in Nature, researchers at UC Berkeley describe yet another creative application for CRISPR: a platform to spur evolution of specific genes inside cells. Their inventive new system, “EvolvR,” lets scientists shake up the DNA letters in their gene of choice until they find the variation that’s just right. The technology opens up countless possibilities, like engineering yeast that efficiently turn waste into biofuels, or developing new human therapeutics.
Researchers have discovered a new, rare type of cell in the human airway. These cells appear to be the primary source of activity of the gene which causes cystic fibrosis.
The vast reservoir of carbon stored beneath our feet is entering Earth’s atmosphere at an increasing rate, according to a new study in the journal Nature. Blame microbes: When they chew on decaying leaves and dead plants, they convert a storehouse of carbon into carbon dioxide that enters the atmosphere.
Un estudio preliminar y publicado en la edición de agosto de Mayo Clinic Proceedings plantea que en algunas personas, la actividad específica de la flora intestinal podría ser la razón por la que son incapaces de bajar de peso, aunque se adhieran estrictamente a la dieta y a un programa de ejercicios.
• When opioids are prescribed following surgery, approximately four percent of the general patient population will continue using opioids for an extended time period • Race and household income were not significant risk factors for prolonged opioid use • Physicians’ prescribing practices may influence patient risk • Patients in the worker’s compensation setting experienced the highest rates of prolonged opioid use
More than 90 percent of people caring for a family member with dementia experience poor sleep, according to new research by the University at Buffalo School of Nursing.
In a recently published study in the journal Nature Microbiology, researchers at Los Alamos National Laboratory show that computer simulations can accurately predict the transmission of HIV across populations, which could aid in preventing the disease.
ORNL story tips: Residents’ shared desire for water security benefits neighborhoods; 3D printed molds for concrete facades promise lower cost, production time; ORNL engineered the edges of structures in 2D crystals; chasing runaway electrons in fusion plasmas; new tools to understand U.S. waterways and identify potential hydropower sites; better materials for 3D-printed permanent magnets could last longer, perform better.
A preliminary study published in the August issue of Mayo Clinic Proceedings suggests that, for some people, specific activities of gut bacteria may be responsible for their inability to lose weight, despite adherence to strict diet and exercise regimens.
More than 60 years after the drug thalidomide caused birth defects in thousands of children whose mothers took the drug while pregnant, scientists at Dana-Farber Cancer Institute have solved a mystery that has lingered ever since the dangers of the drug first became apparent: how did the drug produce such severe fetal harm?
For specialist nurses on neurocritical care units, accompanying patients for imaging scans and other procedures has a major impact on nurse staffing ratios, reports a study in the Journal of Neuroscience Nursing, official journal of the American Association of Neuroscience Nurses. The journal is published in the Lippincott portfolio by Wolters Kluwer.
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.
Mount Sinai researchers have discovered that certain drug cocktails help targeted therapies attack cancer more efficiently while lessening common side effects, according to a study published today in Cancer Research.
