Princeton chemists led by Prof. Todd Hyster have found a way to make a naturally occurring enzyme take on a new, artificial role, which has significant implications for modern chemistry, including pharmaceutical production.
Multiple factors make an effective professional development (PD) program for K-12 teachers. Focusing on content, active learning, collaboration and coaching support and using effective teaching models can broaden the knowledge of science teachers. However, many teachers are short on the resources needed to attend one-time short-term PD programs. The results of one online PD program for teachers will be shared at the American Physiological Society's (APS's) Institute on Teaching and Learning in Madison, Wis.
For many students, essay tests are a source of dread and anxiety. But for professors, these tests provide an excellent way to assess a student's depth of knowledge and critical-thinking skills. At the American Physiological Society's (APS's) Institute on Teaching and Learning in Madison, Wis., Andrew Petzold, PhD, of the University of Minnesota Rochester Center for Learning Innovation, will discuss how a game of chance can lead to increased student preparation and motivation.
Studying abroad can impart valuable, lifelong skills, including foreign language skills, appreciation for other cultures and access to unique learning opportunities. However, the cost remains a major impediment to many students. A course at University of New Hampshire at Manchester offered a study abroad trip during spring break. The cost, a course fee, was potentially covered under financial aid that provides funds for tuition and fees, and created opportunities for commuter students to study abroad.
States that fully implemented Medicaid expansion under the Affordable Care Act saw significant increases for preemptive kidney transplant listings among black and Hispanic patients.
The blood pressure-lowering medication ramipril reduced protein excretion -- or proteinuria -- in children with chronic kidney disease. Greater reductions in proteinuria during the first months of treatment were linked with a lower risk of kidney disease progression.
In states that expanded Medicaid under the Affordable Care Act to cover more low-income individuals, there was an increase in the number of Medicaid beneficiaries who were preemptively waitlisted to receive a kidney transplant. Medicaid expansion was associated with greater gains racial and ethnic minorities in being listed pre-emptively on the transplant waitlist compared with whites.
The innate immune system, our first line of defense against bacterial infection, has a side job that's equally important: fine-tuning our metabolism.
New research shows that highly anxious individuals exert more cognitive control when they make a risky decision compared with less anxious individuals. This in turn leads to less risky decisions.
Researchers led by Mark Rasenick in the University of Illinois at Chicago College of Medicine, describe the molecular mechanisms behind ketamine's ability to squash depression and keep it at bay. They report their findings in the journal Molecular Psychiatry.
A pioneering technique developed to analyze genetic activity of Antarctic worms is helping to predict cerebral palsy. The technique uses next-generation genetic sequencing data to measure how cells control the way genes are turned on or off, and can also be used in other human health care research.
A new study shows that a group of neurons, previously thought to die in the course of development, in fact become incorporated into the brain's cortex. This research has implications for understanding -- and possibly treating --several brain disorders.
Investigators have identified a new cellular pathway that may help explain how arterial inflammation develops into atherosclerosis -- deposits of cholesterol, fats and other substances that create plaque, clog arteries and promote heart attacks and stroke. The findings could lead to improved therapies for atherosclerosis, a leading cause of death worldwide.
Virginia Commonwealth University researchers have discovered a novel strategy for creating superatoms -- combinations of atoms that can mimic the properties of more than one group of elements of the periodic table. These superatoms could be used to create new materials, including more efficient batteries and better semiconductors; a core component of microchips, transistors and most computerized devices.
The key to better treatments for brain injuries and disease may lie in the molecules charged with preventing the clumping of specific proteins associated with cognitive decline and other neurological problems, researchers from Penn report in a new study published in Neurobiology of Disease.
Using transcranial magnetic stimulation and network control theory, researchers have taken a novel approach to understanding how signals travel across the brain's highways and how stimulation can lead to better cognitive function.
Astronomers using the ESO Very Large Telescope, and the NASA/ESA Hubble Space Telescope, have made the most precise test yet of Einstein's general theory of relativity outside the Milky Way. The galaxy ESO 325-G004 distorts light from a galaxy behind it and creates an Einstein ring around its centre. By comparing the mass of ESO 325-G004 with the curvature of space around it, astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity.
In 2014, California voters approved Proposition 47, which reclassified drug possession offenses from felonies to misdemeanors, and in the process reduced the state's prison and jail populations. Now, a study out of UC San Francisco has quantified the effects of the ballot measure, which was at the leading edge of a national movement to reduce incarceration rates and change the criminal justice approach to substance use disorders.
A team of researchers at Sanofi and Mainz University finds no positive action of isomers of the fatty acid derivatives 5- and 9-PAHSA in diabetes models.
Cashing in on materials science, NIST makes a new nickel for use in the U.S. Mint. The work might be useful for building durable high-tech devices like smartphones, too.
