Researchers use radiomics to predict heart attacks

Researchers are using an approach called radiomics to predict future cardiac events like heart attacks, according to a study published in Radiology. Radiomics allows researchers to extract quantitative, or measurable, data from CT images that can reveal disease characteristics not visible in the images alone.

What effect will replacing short-haul flights have on carbon dioxide emissions and international connectivity?

Last December, France obtained approval from the European Commission to prohibit short-haul flights with alternatives by rail taking less than 2.5 hours, in a measure aimed at reducing CO2 emissions and combating climate change.

Risk for alcohol use disorder increased after COVID-19 infection

There appears to have been an increased risk for alcohol use disorder (AUD) after COVID-19 infection versus non-COVID-19 respiratory infections in some time periods during the pandemic, according to a study published online Feb. 9 in JAMA Network Open.

Demographers identify the causes, challenges of a rapidly aging Puerto Rico

The Puerto Rican population is aging rapidly, with the percentage of older adults on the island the 10th highest in the world. Penn State researchers are discovering, for the first time, the causes of population aging and how it will negatively impact Puerto Rico.

A deep reinforcement learning model that allows AI agents to track odor plumes

For a long time, scientists and engineers have drawn inspiration from the amazing abilities of animals and have sought to reverse engineer or reproduce these in robots and artificial intelligence (AI) agents. One of these behaviors is odor plume tracking, which is the ability of some animals, particularly insects, to home in on the source of specific odors of interest (e.g., food or mates), often over long distances.

Defective graphene has high electrocatalytic activity

Scientists from the Moscow Institute of Physics and Technology, Skoltech, and the Russian Academy of Sciences Joint Institute for High Temperatures have conducted a theoretical study of the effects of defects in graphene on electron transfer at the graphene-solution interface. Their calculations show that defects can increase the charge transfer rate by an order of magnitude. Moreover, by varying the type of defect, it is possible to selectively catalyze the electron transfer to a certain class of reagents in solution. This can be very useful for creating efficient electrochemical sensors and electrocatalysts. The findings were published in Electrochimica Acta.

Steep decline in organ transplants amid COVID-19 outbreak

France and the United States, two countries hit hard by the novel coronavirus, have experienced a tremendous reduction in the number of organ donations and solid organ (kidney, liver, heart, and lung) transplant procedures since the onset of the COVID-19 pandemic, according to a new study. By early April, transplant centers in both countries were conducting far fewer deceased donor transplants compared to just one month earlier, with the number of procedures dropping by 91 percent in France and 50 percent in the United States.

Be clear, positive, and targeted, to help public stick to social distancing, governments urged

Clear, positive, messaging that is segmented by age, culture, and geography is key to helping the public stick to social distancing measures to stop the spread of Covid-19 infection, say behavioural experts in a commentary accepted for publication in the Journal of Epidemiology and Community Health.

Being overweight in life, not just childhood, increases risk of heart disease and diabetes

The association between childhood obesity and increased risk of coronary artery disease and type 2 diabetes is due to individual's remaining overweight into adulthood, finds a new University of Bristol study. The research, published in The BMJ, investigated how the genetic influence of being overweight in 453,169 individuals at different stages of life contributed towards their disease risk.
