Raising fluid walls around living cells

Cell culture plates that are in everyday use in biology can be effectively transformed into microfluidic devices, opening paths for biologists to miniaturize cell-based workflows. In a recent report, Ph.D. researcher Cristian …

Spintronic memory cells for neural networks

In recent years, researchers have proposed a wide variety of hardware implementations for feed-forward artificial neural networks. These implementations include three key components: a dot-product engine that can compute …

Oscillating quasiparticles: the cycle of decay and rebirth

Decay is relentless in the macroscopic world: Broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: New research shows that so-called quasiparticles can decay and reorganize …

Revealing ‘hidden’ phases of matter through the power of light

Most people think of water as existing in only one of three phases: Solid ice, liquid water, or gas vapor. But matter can exist in many different phases—ice, for example, has more than ten known phases, or ways that its …

Laser trick produces high-energy terahertz pulses

A team of scientists from DESY and the University of Hamburg has achieved an important milestone in the quest for a new type of compact particle accelerator. Using ultra-powerful pulses of laser light, they were able to produce …

Virus genes help determine if pea aphids get their wings

Many of an organism’s traits are influenced by cues from the organism’s environment. These features are known as phenotypically plastic traits and are important in allowing an organism to cope with unpredictable environments.

Satellite observations improve earthquake monitoring, response

Researchers at the University of Iowa and the U.S. Geological Survey have found that data gathered from orbiting satellites can provide more accurate information on the impact of large earthquakes, which, in turn, can help …

A shady spot may protect species against rapid climate warming

Finding a shady refuge to cool off on a hot day could be more than a lifesaver in a warming world. It might save several species that would otherwise go extinct due to global warming, according to an analysis by ecologists …

Hubble sets sights on an explosive galaxy

When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous—so …

Discovery of light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity …

Modified protein can prevent Alzheimer’s disease in mice

The amyloid precursor protein has always been vilified as a major cause of Alzheimer’s disease. One of its fragments, the amyloid-beta peptide, can break off and accumulate in the brain, giving rise to the puffy white globs …

Examining how people’s emotions are influenced by others

In a new study, Stanford psychologists examined why some people respond differently to an upsetting situation and learned that people’s motivations play an important role in how they react.

Exercise may have different effects in the morning and evening

Researchers from the University of Copenhagen have learned that the effect of exercise may differ depending on the time of day it is performed. In mice, they demonstrate that exercise in the morning results in an increased …

The mast is raised for NASA’s Mars 2020 rover

In this image, taken on June 5, 2019, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, take a moment after attaching the remote sensing mast to the Mars 2020 rover in the Spacecraft Assembly Facility’s …

Better prognosticating for dogs with mammary tumors

Mammary tumors in dogs are the equivalent of breast cancers in people, and, as in the human disease, the canine tumors can manifest in a variety of ways. Some are diagnosed early, others late, and they can be either slow …

Flickering sky islands generate andean biodiversity

A new video shows how climate change connected and disconnected Andean “sky islands” during the past million years. The innovative mathematical model used to make the video was based on fossil pollen records and shows how …

Researchers take two steps toward green fuel

An international collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT) , Japan, has developed a two-step method to more efficiently break down carbohydrates into their single sugar components, …

No evidence for increased egg predation in the Arctic

Climate and ecosystems are changing, but predation on shorebird nests has changed little around the globe over the past 60 years, according to a study by an international team of 60 researchers. The study, published in Science …

Carbon-neutral fuels move a step closer

Chemists at EPFL have developed an efficient process for converting carbon dioxide into carbon monoxide, a key ingredient of synthetic fuels and materials.

Research uncovers elusive process essential to plant greening

Despite how essential plants are for life on Earth, little is known about how parts of plant cells orchestrate growth and greening. By creating mutant plants, UC Riverside researchers have uncovered a cellular communication …

Materials informatics reveals new class of super-hard alloys

A new method of discovering materials using data analytics and electron microscopy has found a new class of extremely hard alloys. Such materials could potentially withstand severe impact from projectiles, thereby providing …

Salmonella resistant to antibiotics of last resort found in US

Researchers from North Carolina State University have found a gene that gives Salmonella resistance to antibiotics of last resort in a sample taken from a human patient in the U.S. The find is the first evidence that the …

Mysterious Majorana quasiparticle is now closer to being controlled for quantum computing

As mysterious as the Italian scientist for which it is named, the Majorana particle is one of the most compelling quests in physics.
