Template to create superatoms, created by VCU researchers, could make for better batteries

Mié, 06/20/2018 - 22:00
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.

First major study comparing robotic to open surgery published in The Lancet

Mié, 06/20/2018 - 22:00

Online professional development boosts teachers' confidence, knowledge

Mié, 06/20/2018 - 22:00
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.

'Exam Roulette' could quell essay-induced anxiety

Mié, 06/20/2018 - 22:00
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.

Study abroad for commuters: a case study at the University of New Hampshire at Manchester

Mié, 06/20/2018 - 22:00
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.

Police killings of unarmed black Americans affect mental health of black community

Mié, 06/20/2018 - 22:00
Black Americans are nearly three times more likely to be killed by police than their white counterparts, with even larger disparities among those who are unarmed. The trend is also harming the mental health of the black community, according to new research published in The Lancet.

The Lancet: Police killings of unarmed black Americans impact mental health of wider black American population

Mié, 06/20/2018 - 22:00
Police killings of unarmed black Americans have adverse effects on the mental health of black American adults in the general population, according to a new population-based study. With police killings of unarmed black Americans widely perceived to be a symptom of structural racism, the findings highlight the role of structural racism as a driver of population health disparities, and support recent calls to treat police killings as a public health issue.

New technology helps to improve treatment for NHS patients with depression

New technology that has been found to reduce the probability of patients with depression and anxiety deteriorating during NHS psychological treatment by 74 percent.

Medicaid Expansion increased low-income patient access to kidney transplants

Mié, 06/20/2018 - 22:00
States that fully implemented Medicaid expansion under the Affordable Care Act saw significant increases for preemptive kidney transplant listings among black and Hispanic patients.

'Antifreeze' molecules may stop and reverse damage from brain injuries

Mié, 06/20/2018 - 22:00
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.

Scientists discover how brain signals travel to drive language performance

Mié, 06/20/2018 - 22:00
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.

VLT makes most precise test of Einstein's general relativity outside Milky Way

Mié, 06/20/2018 - 22:00
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.

Antidiabetic action of natural fatty acid derivatives not confirmed

Mié, 06/20/2018 - 22:00
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.

Coining less expensive currency: bringing down the cost of making nickels

Mié, 06/20/2018 - 22:00
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.

Writing away the body image blues

Mié, 06/20/2018 - 22:00
Body dissatisfaction among women is widespread and can lead to a number of worrisome outcomes, including eating disorders, depression and anxiety. While researchers know a lot about what makes women's body image worse, they are still short on empirically supported interventions for improving women's body image. Northwestern psychology professor Renee Engeln tested the effect of three specific writing exercises on college women's body satisfaction, along with co-author Natalie G. Stern.

Crisis can force re-evaluation and derail efforts to reach goals

Mié, 06/20/2018 - 22:00
Setbacks are to be expected when pursuing a goal, whether you are trying to lose weight or save money. The challenge is getting back on track and not giving up after a difficulty or crisis, says an Iowa State marketing professor working on practical ways to help people stick to health-related goals.
