Yale University has begun a multi-phase renovation of the former Wright Nuclear Structure Laboratory that will reinvent the landmark nuclear physics lab for a new era in physics research.

Expected to take at least three years, the project will transform the bunker-like home of what once was the world’s most powerful atom smasher of its kind into a site for teaching, research, and development related to two of the hottest topics in 21st-century physics — the study of neutrinos and the hunt for dark matter.

Health interventions can contribute to academic achievement

There is a strong relationship between a student’s personal health and their academic achievement in school, new research by Yale University suggests. The study found that school, home and community environments that promote good personal health contribute to higher levels of achievement.

The study examines the relationship between a variety of health factors and students’ standardized test scores. The most important predictors of academic achievement were having no television in the bedroom, maintaining a healthy weight, being physically fit, having a secure source of healthy food, and rarely eating at fast-food restaurants. Other significant factors were not drinking soda or other sweetened drinks and getting enough sleep. (more…)

Weather changes may be linked to stroke hospitalizations

Stroke hospitalization rates appear to rise and fall with sharp changes in outdoor temperature and dew point, a pilot study led by the Yale School of Public Health has found. The research, presented this week at the American Stroke Association’s International Stroke Conference 2014, shows an association of stroke hospitalizations with exposure to extreme daily temperature and dew point fluctuations.

The study examined Medicare, Medicaid, and private insurance data from hospitals across the United States. The researchers looked at 157,130 hospital discharges in 2010-2011 for ischemic stroke (caused by a blood clot that blocks blood flow in or leading to the brain). The researchers also obtained temperature and dew point data during the same period and localized it to the county level. (more…)

Infra-red film helped photojournalist ‘step over the threshold’ to capture war’s impact

It wasn’t until he began taking a more artistic approach that Richard Mosse felt his photographs were truly capturing the horror of the conflict in the Congo, the artist told a group of undergraduates and graduates on Feb. 5.

Mosse spoke about the process behind his most recent project, “The Enclave,” at the Yale School of Art. The talk was sponsored by the Poynter Fellowship in Journalism. (more…)

Yale study: Forest emissions, wildfires explain why ancient Earth was so hot

The release of volatile organic compounds from Earth’s forests and smoke from wildfires 3 million years ago had a far greater impact on global warming than ancient atmospheric levels of carbon dioxide, a new Yale study finds.

The research provides evidence that dynamic atmospheric chemistry played an important role in past warm climates, underscoring the complexity of climate change and the relevance of natural components, according to the authors. They do not address or dispute the significant role in climate change of human-generated CO2 emissions. (more…)

Dead Star and Distant Black Holes Dazzle in X-Rays

Two new views from NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, showcase the telescope’s talent for spying objects near and far. One image shows the energized remains of a dead star, a structure nicknamed the “Hand of God” after its resemblance to a hand. Another image shows distant black holes buried in blankets of dust.

“NuSTAR’s unique viewpoint, in seeing the highest-energy X-rays, is showing us well-studied objects and regions in a whole new light,” said Fiona Harrison, the mission’s principal investigator at the California Institute of Technology in Pasadena, Calif. (more…)

UD oceanographer reports on human-caused changes to carbon cycling

Carbon dioxide pumped into the air since the Industrial Revolution appears to have changed the way the coastal ocean functions, according to a new analysis published this week in Nature.

A comprehensive review of research on carbon cycling in rivers, estuaries and continental shelves suggests that collectively this coastal zone now takes in more carbon dioxide than it releases. The shift could impact global models of carbon’s flow through the environment and future predictions related to climate change. (more…)

There is no approved medicine to treat polyomaviruses, which afflict people with weakened immune systems, but scientists have found that a chemical compound called Retro-2 is able to reduce significantly the infectivity and spread of the viruses in lab cell cultures. Now they are working to improve it.

PROVIDENCE, R.I. [Brown University] — A team of scientists reports that a small-molecule compound showed significant success in controlling the infectivity and spread of three polyomaviruses in human cell cultures. To date there has been no medicine approved to treat such viruses, which prey on transplant recipients, people with HIV, and others whose immune systems have been weakened. (more…)
