Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and sort specific molecules for
New MBARI research on a field of pockmarks—large, circular depressions on the seafloor—offshore of Central California has revealed that powerful sediment flows, not methane gas eruptions, maintain these prehistoric formations.
Using the Keck II telescope in Hawaii, astronomers have observed a nearby brown dwarf known as HD 33632 Ab. Results of the observational campaign, presented in a paper published May 14 on the pre-print server arXiv, provide more insights into the properties of this substellar
A trio of hexagonal islands could generate solar electricity to power a process that accelerates coral growth, with space for a research lab and a garden
From camel drivers in the Sahara to nomads on the Mongolian steppe, traditional herders the world over rely on earth's wildest open spaces to support an ancient way of life.
Like Charles Darwin did in 1831, a group of scientists and environmentalists last year set sail from the English port of Plymouth, headed for the Galapagos islands off the coast of Ecuador.
Indian authorities in the capital have ordered schools shut early for the summer holiday, after temperatures hit 47.4 degrees Celsius (117 degrees Fahrenheit) with Delhi gripped by a "severe heat wave".
The U.S. Environmental Protection Agency's method of detecting methane leaks at landfills is flawed, and emissions of this powerful heat-trapping gas are likely much higher than what is being reported, according to a new study analyzing landfills in Illinois and seven other
The authors of a major study on the critically endangered Arabian leopard say that the release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of
For Wendy Hood and Geoffrey Hill in Biological Sciences, Andreas Kavazis in Kinesiology, and their team, Emma Rhodes, Paulo Mesquita, and Jeff Yap, traveling the country to unlock the mystery of mitochondria in migrating aviary species has allowed them to make a significant
Since 2015, the Amazon has been slower to recover from increasing drought events, but, overall, the rainforest still shows a remarkable resilience. New international research led by KU Leuven Earth and environmental scientists shows that forest degradation due to drought has
A team of researchers from The University of Queensland has found employees experience more stress at work when interrupted with requests for unnecessary or unreasonable tasks.
New data analysis indicates that NASA and its partners could have more cost-effective methods for dealing with the growing issue of orbital debris than previously thought.
Future missions to the moon and Mars must address many challenges, including preventing loss of bone and muscle tissue in astronauts. Research on the International Space Station is helping to address this challenge.
An Oregon State University study has found evidence that Indigenous groups in the Pacific Northwest were intentionally harvesting edible camas bulbs at optimal stages of the plant's maturation as far back as 3,500 years ago.
Few things in nature are as predictable as ocean tides. Driven by the moon's and sun's gravitational pull, these persistent, short-period, and large-magnitude phenomena are apparent in nearly all types of oceanographic and satellite observations. They also directly impact the
A research team collaborated to identify the principle of an eco-friendly energy-based soft mechanoluminescent complex that emits light without batteries. It is expected to be applied in various fields, such as optical sensors, artificial skin, and displays. The team includes
More than 150 years ago, some 15,000 Chinese workers arrived in the U.S. to help construct the country's first transcontinental railroad, which connected the West Coast with the East Coast's rail network.
Micelles assemble in water from amphiphilic molecules, composed of hydrophilic and hydrophobic frameworks. They can be found all around us, for example in soaps, detergents, and shampoos. Their main application is the water-solubilization of insoluble molecules through
An electrochemical process developed at Georgia Tech could offer new protection against bacterial infections without contributing to growing antibiotic resistance.
As humanity grapples with the fight against climate change, reducing greenhouse gas emissions is urgently necessary. One way to achieve this is through the carbon offset market, where organizations or individuals can buy credits from emissions-reducing projects.
A paper, titled "Global Mercury Concentrations in Biota: Their Use as a Basis for a Global Biomonitoring Framework" and published in the journal Ecotoxicology, describes for the first time currently available mercury data for fish and wildlife on a global scale. Data from the
Chicken breast jerky (CBJ) is a popular pet food due to its high crude protein content and long shelf life. In the production of CBJ, the drying process is a crucial step. However, the physicochemical and functional properties of CBJ depend on the drying method used.
