Researchers connect lightning with gamma-ray phenomena in clouds

University of Tokyo graduate student Yuuki Wada with colleagues from Japan have discovered a connection between lightning strikes and two kinds of gamma-ray phenomena in thunderclouds. The research suggests that in certain conditions, weak gamma-ray glows from thunderclouds may precede lightning bolts and their accompanying gamma-ray flashes.

Biochip advances enable next-generation sequencing technologies

Biochips are essentially tiny laboratories designed to function inside living organisms, and they are driving next-generation DNA sequencing technologies. This powerful combination is capable of solving unique and important biological problems, such as single-cell, rare-cell or rare-molecule analysis, which next-generation sequencing can't do on its own.

Levanluhta jewellery links Finland to a European exchange network

The Levänluhta water burial site, dating back to the Iron Age (300-800 CE), is one of Finland's most famous archaeological sites. Nearly one hundred individuals, mainly women or children, were buried in a lake located at Isokyrö in SW Finland, during the Iron Age. Some of the deceased were accompanied by arm rings and necklaces made out of copper alloy, bronze or brass.

California's mighty predator, the mountain lion, faces 'extinction vortex'

As the mountain lions of Southern California approach what some experts call an "extinction vortex," environmentalists are demanding that state officials grant the big cats protective status—a move that could potentially ban development on thousands of acres of prime real estate.

Air pollution found to affect marker of female fertility in real-life study

Ovarian reserve, a term widely adopted to reflect the number of resting follicles in the ovary and thus a marker of potential female fertility, has been found in a large-scale study to be adversely affected by high levels of air pollution.

A new 'golden' age for electronics?

One way that heat damages electronic equipment is it makes components expand at different rates, resulting in forces that cause micro-cracking and distortion. Plastic components and circuit boards are particularly prone to damage due to changes in volume during heating and cooling cycles. But if a material could be incorporated into the components that compensates for the expansion, the stresses would be reduced and their lifetime increased.

Which climates are best for passive cooling technologies?

A group of University of California, San Diego researchers set out to gain a better understanding of the thermal balance of power plants and surfaces, like heliostat mirrors or solar panels, when exposed to both solar (shortwave) and atmospheric (longwave) radiation. They quickly realized that they would first need to determine what roles cloud cover and relative humidity play in the transparency of the atmosphere to radiation at temperatures common on Earth.

Teaching robots what humans want

Told to optimize for speed while racing down a track in a computer game, a car pushes the pedal to the metal … and proceeds to spin in a tight little circle. Nothing in the instructions told the car to drive straight, and so it improvised.

Drug combo slows progression in advanced breast cancer

(HealthDay)—Treatment with a combination of alpelisib and fulvestrant prolongs progression-free survival among patients with PIK3CA-mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer, according to a phase 3 study recently published in the New England Journal of Medicine.

Shorter rotations in intensive care units mitigate burnout among physicians

Shortening the length of rotations in a medical intensive care unit (MICU) from the traditional 14-consecutive day schedule to only seven days helps mitigate burnout among critical care physicians, according to a new Penn Medicine pilot study. The study, published today in the American Journal of Respiratory and Critical Care Medicine, is the first to validate the efficacy of a truncated rotation in reducing the rate of burnout among critical care physicians.

Artificial intelligence learns to recognize nerve cells by their appearance

Is it possible to understand the brain? Science is still far from answering this question. However, since researchers have started training artificial intelligence on neurobiological analyses, it seems at least possible to reconstruct the cellular structure of a brain. New artificial neural networks developed by the Max Planck Institute of Neurobiology and Google AI can now even recognize and classify nerve cells independently based on their appearance.
