DeNeRD: an AI-based method to process whole images of the brain

Researchers at the University of Zurich's Brain Research Institute have recently developed a technique to automatically detect neurons of different types in a variety of brain regions at different developmental stages. They ...

New study uncovers 'magnetic' memory of European glass eels

A new study led by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and at the Institute of Marine Research in Norway found that European glass eels use their magnetic sense ...

Lessons from Ridgecrest earthquake sequence

The largest earthquake sequence in Southern California in two decades has taught scientists that large earthquakes can occur in a more complex fashion than commonly assumed. The sequence also loaded up strain on a nearby ...

Newly discovered microbes band together, 'flip out'

When researchers in Nicole King's lab looked through a microscope at the strange organisms they had collected in Curaçao, they saw sheets of cells clustered together in a pattern that resembled skin. That was unusual enough, ...

How human brain development diverged from great apes

Researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, Institute of Molecular and Clinical Ophthalmology Basel, and ETH Zurich, Switzerland, have presented new insights into the development ...

Male and female mice have different brain cells

Caltech researchers have discovered rare brain cell types that are unique to male mice and other types that are unique to female mice. These sex-specific cells were found in a region of the brain that governs both aggression ...

How aerosols affect our climate

For many, the word "aerosol" might conjure thoughts of hairspray or spray paint. More accurately, though, aerosols are simply particles found in the atmosphere. They can be human-made, like from car exhaust or biomass burning, ...

SUPERB survey detects new slowly-spinning radio pulsar

Astronomers have detected a new slowly rotating radio pulsar as part of the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB). The newly found object, designated PSR J2251−3711, turns out to be one of the slowest ...

The clumpy and lumpy death of a star

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this "new star" was far beyond ...

Mars InSight's 'mole' is moving again

NASA's InSight spacecraft has used its robotic arm to help its heat probe, known as "the mole," dig nearly 2 centimeters (3/4 of an inch) over the past week. While modest, the movement is significant: Designed to dig as much ...

Scientists discover fractal patterns in a quantum material

A fractal is any geometric pattern that occurs again and again, at different sizes and scales, within the same object. This "self-similarity" can be seen throughout nature, for example in a snowflake's edge, a river network, ...

Deep-sea explorers seek out sunken World War II ships

MIDWAY ATOLL, Northwestern Hawaiian Islands (AP)—Deep-sea explorers scouring the world's oceans for sunken World War II ships are honing in on debris fields deep in the Pacific, in an area where one of the most decisive ...

A new approach to reconstructing protein evolution

There are an estimated 20,000 to 30,000 proteins at work in cells, where they carry out numerable functions, says computational molecular biologist Roman Sloutsky at the University of Massachusetts Amherst. "One of the central ...

First report of cotton blue disease in the United States

In August 2017, Kathy S. Lawrence, a plant pathologist at Auburn University, received a call from Drew Schrimsher of Agri-AFC, who had discovered foliar distortion and leaf curling and rolling on approximately 50,000 acres ...

Stranded whales detected from space

A new technique for analysing satellite images may help scientists detect and count stranded whales from space. Researchers tested a new detection method using Very High Resolution (VHR) satellite images from Maxar Technologies ...

How roots grow hair

The roots of plants can do a lot of things: They grow in length to reach water, they can bend to circumvent stones, and they form fine root hairs enabling them to absorb more nutrients from the soil. A team of researchers ...

Spiral arms in a young accretion disk around a baby star

An international research team, led by Chin-Fei Lee at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has detected a pair of spiral arms in an accretion disk around a protostar (baby star), using ...

What happens under the Yellowstone volcano?

Yellowstone National Park in the USA, with its geysers and hot springs, is a major attraction for tourists. However, especially in times of little news, the media often focuses on the Yellowstone supervolcano, which last ...

Future flash drought will increase over humid regions

Flash drought is a new phenomenon with increasing prominence due to global warming. Drought develops rapidly without sufficient early warning, and has stricken the world with severe impacts during recent years, such as the ...
