A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.

Researchers at North Carolina State University and the University of North Carolina Greensboro made a surprising finding while examining areas where sand flies rear their young: a new species of bacteria that is highly attractive to pregnant, or gravid, sand flies. The findings could advance the production of ecologically safe baits or traps to reduce sand fly populations.
NASA and Boeing are now targeting July 30 for an uncrewed test flight of the aerospace company's troubled Starliner capsule to the International Space Station, they announced Thursday.
How much water sloshes around in Earth's lakes, rivers, and oceans? And how does that figure change over time? The upcoming Surface Water and Ocean Topography (SWOT) mission plans to find out. Targeting a late-2022 launch date, this SUV-size satellite will measure the height of Earth's water. SWOT will help researchers understand and track the volume and location of water—a finite...
Yawning doesn't need be a sign of boredom. Rather, it appears to be a measure of brain size. Vertebrates with larger brains yawn longer, according to a study of more than one hundred species of mammals and birds. The findings of the study, which was conducted by an international team of scientists centered around biologist Jorg Massen of Utrecht University (NL) and Andrew Gallup of the State...
Evidence of recent volcanic activity on Mars shows that eruptions could have taken place within the past 50,000 years, a paper by Planetary Science Institute Research Scientist David Horvath says.
A team of chemists and physicists at Utrecht University has succeeded in designing a new type of catalyst. By combining two metals with atomic precision they created a highly effective catalytic material. The team, led by Prof. Petra de Jongh (Chemistry) and Prof. Alfons van Blaaderen (Physics), are publishing their findings in Nature Materials today.
Cece Linder was living in a 770-square-foot apartment outside Washington, D.C., last spring when the area went into lockdown because of the coronavirus pandemic.
A research team from Brown University has made a major step toward improving the long-term reliability of perovskite solar cells, an emerging clean energy technology. In a study to be published on Friday, May 7 in the journal Science, the team demonstrates a "molecular glue" that keeps a key interface inside cells from degrading. The treatment dramatically increases cells' stability and...
The findings, published in the journal Science today, demonstrate how integrating vertical descent and horizontal gene transfer can be used to infer the root of the bacterial tree and the nature of the last bacterial common ancestor.
Like conductors of a spooky symphony, researchers at the National Institute of Standards and Technology (NIST) have "entangled" two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks.
In the 150 years since Charles Darwin speculated that humans originated in Africa, the number of species in the human family tree has exploded, but so has the level of dispute concerning early human evolution. Fossil apes are often at the center of the debate, with some scientists dismissing their importance to the origins of the human lineage (the "hominins"), and others conferring them starring...
If paleontologists had a wish list, it would almost certainly include insights into two particular phenomena: how dinosaurs interacted with each other and how they began to fly.
Cells are more resilient to environmental perturbations than previously thought, Toronto researchers have found. The finding will enable scientists to translate observations of the effects of drugs or mutations on cells grown in a lab setting as they seek to gain a better understanding of cellular function and to develop new diagnostics and treatments.
An international team of 92 scientists and conservationists has joined forces to create the first-ever global atlas of ungulate (hooved mammal) migrations, working in partnership with the Convention on the Conservation of Migratory Species of Wild Animals (CMS), a UN treaty.
Today's 10,000 species of birds live in virtually every habitat on Earth, but only a handful have adaptations enabling them to hunt active prey in the dark of night. Scientists have long wondered whether theropod dinosaurs—the group that gave rise to modern birds—had similar sensory adaptations.
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave like waves. As a result, particles cannot have a well-defined position and momentum simultaneously. For instance, measuring the momentum of a particle leads to a...
Industry could cheaply and easily slash humanity's methane emissions by at least 30 percent in a decade, the United Nations said Thursday, adding that such cuts would slow global warming and prevent hundreds of thousands of deaths.
Look at the fine print to understand the climate goals that governments and companies have set and search for one term in particular: net-zero.
Young people need additional support and protection in the criminal justice system because they are more susceptible to pleading guilty when innocent, a new study argues.
For millennia, humans in the high latitudes have been enthralled by auroras—the northern and southern lights. Yet even after all that time, it appears the ethereal, dancing ribbons of light above Earth still hold some secrets.
Although the fairy tale of the wicked stepmother is a tale as old as time, the effects of blending children with their new stepfamilies may not be as grim as once thought.
The European Alps is certainly one of the most scrutinized mountain range in the world, as it forms a true open-air laboratory showing how climate change affects biodiversity.
Cells of all life forms are surrounded by a membrane that is made of phospholipids. One of these are the cardiolipins, which form a separate class due to their unique structure. When studying the enzyme that is responsible for producing cardiolipins in archaea (single-cell organisms that constitute a separate domain of life), biochemists at the University of Groningen made a surprising discovery....
Scientists at Tokyo Institute of Technology experimentally verify the existence of exotic surface conduction states in topological semimetals (TSMs), materials that lie at the boundary between conductors and insulators, by performing voltage scans of these surface states on a thin film sample of a TSM. The findings can pave the way for future study and exploitation of such conduction states in...
