Climate-friendly microbes chomp dead plants without releasing heat-trapping methane
A new real-time, 3D motion tracking system developed at the University of Michigan combines transparent light detectors with advanced neural network methods to create a system that could one day replace LiDAR and cameras in autonomous technologies.
With new optical device, engineers can fine tune the color of light
The tree of life just got a little bigger: A team of scientists from the U.S. and China has identified an entirely new group of microbes quietly living in hot springs, geothermal systems and hydrothermal sediments around the world. The microbes appear to be playing an important role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane.
Fossils of 'giant cloud rats' discovered in Philippine caves
Among the first lessons any grade school science student learns is that white light is not white at all, but rather a composite of many photons, those little droplets of energy that make up light, from every color of the rainbow—red, orange, yellow, green, blue, indigo, violet.
Brought in by humans, beavers threaten Patagonia forest
Rats, by and large, aren't terribly popular animals. But while you don't want an infestation of common black rats living in your house, their distant cousins in the Philippines are downright cuddly. These "giant cloud rats" live in the treetops of misty mountain forests, and they fill an ecological role occupied by squirrels in the US. And, it turns out, we have new evidence that they've been...
The global economic response to climate change: what's the plan?
The Karukinka natural park on Chile's side of the Tierra del Fuego archipelago guards a treasure trove of ancient beech trees saved from the chainsaws of loggers.
Wild horses flourish in Chernobyl 35 years after explosion
World leaders participating in the virtual Earth Day summit are unanimous: fighting climate change will be good for economic growth worldwide.
Astronauts arrive at pad for SpaceX flight on used rocket
Down an overgrown country road, three startled wild horses with rugged coats and rigid manes dart into the flourishing overgrowth of their unlikely nature reserve: the Chernobyl exclusion zone.
SpaceX set for pre-dawn launch to ISS
Four astronauts arrived at their launch pad early Friday morning for a SpaceX flight to the International Space Station, the company's third bon voyage for a NASA crew in under a year.
Research paves way for improved lasers, communications
SpaceX is set to launch its third crew to the International Space Station an hour before sunrise Friday, recycling a rocket and spacecraft for the first time.
Using spatial distance strategically with luxury and popular product displays
New photonics research paves the way for improved lasers, high-speed computing and optical communications for the Army.
Law professor argues for removing police from traffic enforcement
Researchers from Nanjing University, National Sun Yat-sen University, and Northwestern University published a new paper in the Journal of Marketing that shows that the spatial distance between products and consumers can affect perceived value and willingness to pay.
Chemists show ions' staged release from gold-silver nanoparticles could be useful property
University of Arkansas law professor Jordan Blair Woods challenges the conventional wisdom that only police can enforce traffic laws.
Finding new life for wine-grape residue
There's gold in them thar nanoparticles, and there used to be a lot of silver, too. But much of the silver has leached away, and researchers want to know how.
Teaching pupils to 'think like Da Vinci' will help them to take on climate change
California produces nearly 4 million tons of world-class wine each year, but with that comes thousands of tons of residue like grape skins, seeds, stems and pulp. What if scientists could harness that viticultural waste to help promote human health?
Radar satellites can better protect against bushfires and floods
A radically reformed approach to education, in which different subjects teach connected themes, like climate change or food security, is being proposed by researchers, who argue that it would better prepare children for future crises.
Naturally GM: Crops steal genes from other species to accelerate evolution
New research led by Curtin University has revealed how radar satellites can improve the ability to detect, monitor, prepare for and withstand natural disasters in Australia including bushfires, floods and earthquakes.
Study uncovers human-to-cat transmission of the virus that causes COVID-19
Grass crops are able to bend the rules of evolution by borrowing genes from their neighbors, giving them a competitive advantage, a new study has revealed.
New species of dumbo octopus identified using minimally invasive techniques
New research provides evidence that people have transmitted SARS-CoV-2, the virus that causes COVID-19, to cats during the pandemic in the UK. The study, which is published in Veterinary Record, detected the virus last year in cats that developed mild or severe respiratory disease.
A new species of deep-sea dwelling dumbo octopus called Grimpoteuthis imperator sp. nov. has been described using a combination of MRI, micro-CT and minimally invasive gene analysis rather than traditional dissection methods. The findings are presented in the open access journal BMC Biology.

How a space doctor keeps astronauts healthy on the ISS
Study paves the way for new photosensitive materials
From muscle loss to radiation exposure and the psychological effects of confinement, spaceflight takes a toll on those lucky enough to experience it.
Major Everglades restoration project to break ground this year
Photocatalysts are useful materials, with a myriad of environmental and energy applications, including air purification, water treatment, self-cleaning surfaces, pollution-fighting paints and coatings, hydrogen production and CO2 conversion to sustainable fuels.
Ancient Indigenous forest gardens promote a healthy ecosystem, says study
A key project in the restoration of the Everglades moved forward Thursday with the signing of an agreement between Florida and the federal government to construct a huge reservoir south of Lake Okeechobee.
Machine learning model generates realistic seismic waveforms
A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests—cared for as "forest gardens"—contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators. The findings are published today in Ecology and Society.
Scientists uncover structure of light-driven enzyme with potential biofuel applications
A new machine-learning model that generates realistic seismic waveforms will reduce manual labor and improve earthquake detection, according to a study published recently in JGR Solid Earth.
Although many organisms capture and respond to sunlight, enzymes—proteins that catalyze biochemical reactions—are rarely driven by light. Scientists have identified only three types of natural photoenzymes so far. The newest one, discovered in 2017, is fatty acid photodecarboxylase (FAP). Derived from microscopic algae, it uses blue light to catalyze the conversion of fatty acids, found in...
