Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
Businesses trying to come clean about their impact on nature can end up concealing more than they reveal
Humans have overfished the ocean, cleared forests, polluted water and created a climate crisis by burning fossil fuels. These actions are affecting biodiversity around the world, from remote islands to our own backyards......»»
Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»

X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
Forever chemicals persist through waste incineration, researcher finds
PFAS, often called "forever chemicals," present in municipal solid waste can survive the high temperatures of waste incineration and continue to spread into the environment via residues from waste-to-energy plants......»»
New material with wavy layers of atoms exhibits unusual superconducting properties
MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves over and over to create a macroscopic sample that c.....»»
Independent origins of frog glue and its role in predator evasion
Skin-secreted adhesives, or glues, are highly effective defense adaptations that have evolved recurrently in a small number of amphibians. From an ecological standpoint, this rapidly solidifying material—essentially, a sticky slime—encumbers the.....»»
Bioengineers create new substrate to study wood-decomposing enzyme
Researchers want to transform the natural and abundant resource wood into useful materials, and central to that is a molecular machine found in fungi that decomposes the complex raw material into its basic components......»»
Template synthesis creates multilayered perovskites with unique ferroelectric behavior
A group of Nagoya University researchers in Japan has synthesized 4- and 5-layered versions of the important electrical material perovskite. Analyzing the mechanism of ferroelectricity in the material, they found it has a unique function: the materia.....»»
Ocean sediment is a "mudtropolis"—meet the carbon-cycling creatures thriving beneath the seabed
Sitting in darkness, deep below the sunlit surface, an iridescent nightmare awaits its prey. With precision and speed, it strikes and slices a passing fish clean in half with a set of jaws twice the width of its head. The armor-plated creature retrea.....»»
Tiny robots and AI algorithms could help to craft material solutions for cleaner environments
Many human activities release pollutants into the air, water and soil. These harmful chemicals threaten the health of both people and the ecosystem. According to the World Health Organization, air pollution causes an estimated 4.2 million deaths annu.....»»
Over 3,600 food packaging chemicals found in human bodies
More than 3,600 chemicals used in food packaging or preparation have been detected in human bodies, some of which are hazardous to health, while little is known about others, a study said Tuesday......»»
Study sheds light on trade-off between noise and power in nanoscale heat engines
Thanks to nanoscale devices as small as human cells, researchers can create groundbreaking material properties, leading to smaller, faster, and more energy-efficient electronics. However, to fully unlock the potential of nanotechnology, addressing no.....»»
Study finds mine-drainage treatment cost effective, but far more costs lay ahead
New research led by the University of Pittsburgh shows that state and federal appropriations allowing Pennsylvania to treat abandoned mine drainage works to both successfully and cost effectively clean up the acidic water—particularly to the benefi.....»»
Using sunlight to turn greenhouse gases into valuable chemicals
McGill University researchers have harnessed the power of sunlight to transform two of the most harmful greenhouse gases into valuable chemicals. The discovery could help combat climate change and provide a more sustainable way to produce certain ind.....»»
Antarctic research finds exceptional warm air intrusions and omnipresent aerosol layers in the stratosphere
Extremely clean air on the ground, warm air intrusions and sulfate aerosol at high altitudes—a Leipzig research project has gained new insights into clouds in Antarctica. From January to December 2023, the vertical distribution of aerosol particles.....»»
Exploring ternary metal sulfides as electrocatalysts for carbon dioxide reduction reactions
One of the most promising avenues for actively reducing CO2 levels in the atmosphere is recycling it into valuable chemicals via electrocatalytic CO2 reduction reactions. With a suitable electrocatalyst, this can be achieved under mild conditions and.....»»
Printed engines propel the next industrial revolution
In the fall of 2023, NASA hot fire tested an aluminum 3D printed rocket engine nozzle. Aluminum is not typically used for 3D printing because the process causes it to crack, and its low melting point makes it a challenging material for rocket engines.....»»
