A new study indicates that cancer patients and survivors have a ready weapon against fatigue and “chemo brain”: a brisk walk.

Researchers at the University of Illinois, along with collaborators at Digital Artefacts in Iowa City, Iowa, and Northeastern University in Boston, looked at the association between physical activity, fatigue and performance on cognitive tasks in nearly 300 breast cancer survivors.

Mindfulness training and hypnotic suggestion significantly reduced acute pain experienced by hospital patients, according to a new studypublished in the Journal of General Internal Medicine.

New research is challenging the age-old adage that money can’t buy happiness.

The study, led by researchers at the University of British Columbia and Harvard Business School, suggests that using money to buy free time— such as paying to delegate household chores like cleaning and cooking— is linked to greater life satisfaction.

A new way of producing the seasonal flu vaccine could speed up the process and provide better protection against infection.

The first in-car measurements of exposure to pollutants that cause oxidative stress during rush hour commutes has turned up potentially alarming results. The levels of some forms of harmful particulate matter inside car cabins was found to be twice as high as previously believed.

Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period. Exhaust composition, however, changes rapidly enough for drivers to experience different conditions inside their vehicles than these roadside sensors. Long-term sampling also misses nuanced variabilities caused by road congestion and environmental conditions.

This summer, scientists in California are releasing 20 million mosquitoes in an effort to shrink the population of mosquitoes that can carry diseases.

The costs and complications of diabetes could overwhelm healthcare systems in Sub-Saharan Africa and reach US$59.3 billion by 2030 if rates double, according to the Lancet Diabetes and Endocrinology Commission.

Time is of the essence when treating a patient undergoing a heart attack. Cardiac surgeons attempt to quickly stabilize the heart by applying reperfusion, a technique that restores oxygen to the heart by opening up blocked vessels with balloons and stents. While reperfusion can restore cardiac function, such sudden infusions of oxygen can also further injure severely depleted regions of the heart.

“It’s a double-edged sword,” says Anthony McDougal, a graduate student in MIT’s Department of Mechanical Engineering. “The rapid return of oxygen is necessary for the heart to survive, but it could also overwhelm the heart.”

Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble.

In 2014, a team of researchers led by a paleobiologist from the University of Missouri found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes, or flatworms. The team cautioned that the rise could lead to outbreaks in human infections if left unchecked. Now, an international team from Mizzou and the Universities of Bologna and Florida has found that rising seas could be detrimental to human health on a much shorter time scale. Findings from their study in northern Italy suggest that parasitic infections could increase in the next century, if history repeats itself.
