The Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to protect the Earth from this high-energy solar activity.

But when this field comes into contact with the sun's magnetic field — a process called "magnetic reconnection" — powerful electrical currents from the sun can stream into Earth's atmosphere, whipping up geomagnetic storms and space weather phenomena that can affect high-altitude aircraft, as well as astronauts on the International Space Station.

In the tropical highlands of South America and East Africa, cool temperatures have historically kept mosquito-borne diseases, such as malaria, at bay. New research by Howard Hughes Medical Institute (HHMI) scientists shows that as annual temperatures rise in these areas, malaria can spread to populations in higher elevations that had historically not been at as much risk of being infected by malaria parasites.

A team of researchers led by Mayland Chang and Shahriar Mobashery have discovered a new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and other drug-resistant bacteria that threaten public health. 

Changes to two previously unstudied genes are the centerpiece of a new theory regarding the cause and development of endometriosis, a chronic and painful disease affecting 1 in 10 women.

The discovery by Northwestern Medicine scientists suggests epigenetic modification, a process that enhances or disrupts how DNA is read, is an integral component of the disease and its progression. Matthew Dyson, research assistant professor of obstetrics and gynecology at Northwestern University Feinberg School of Medicine and and Serdar Bulun, MD, chair of obstetrics and gynecology at Feinberg and Northwestern Memorial Hospital, also identified a novel role for a family of key gene regulators in the uterus.

We often think of playing fair as an altru­istic behavior. We're sac­ri­ficing our own poten­tial gain to give others what they deserve. What could be more self­less than that? But new research from North­eastern Uni­ver­sity assis­tant pro­fessor of phi­los­ophy Rory Smead sug­gests another, darker origin behind the kindly act of fairness.

ITHACA, N.Y. – To buy, or not to buy? That is the question for the more than 5 million annual visitors to New York's wineries. Cornell University researchers found that customer service is the most important factor in boosting tasting room sales, but sensory descriptions of what flavors consumers might detect were a turn-off.

The findings stem from two studies on how the tasting room experience affects customer purchases and what wineries can do to create satisfied sippers, published in the current issue of the International Journal of Wine Business Research.
