A 2D platform of molybdenum, sulfur and selenium is adept at detecting biomolecules via surface-enhanced Raman spectroscopy. Its nonmetallic nature helps by curtailing background noise.
New 'lean lab' management principles are demonstrating benefits that include cost savings, increased productivity, and a strong safety record.
Biomedical engineers have devised a new imaging device capable of measuring both the thickness and texture of the various layers of the retina. The advance could be used to detect a biomarker of Alzheimer's disease, potentially offering a widespread early warning system for the disease.
Evolutionary biologists studying populations of hybrid fish have found two genes that contribute to melanoma - only the second time people have identified specific genes associated with dysfunction in hybrid vertebrates.
Humans have struggled to reduce the loss of livestock to carnivores for thousands of years, and yet, solutions remain elusive. According to a new study, solving this ancient puzzle requires going back to Ecology 101. Simply put, getting in the mind of predators -- considering how they hunt, how their prey behaves and the landscape -- will help wildlife managers discourage wild carnivores from...
Researchers revealed the largest and hottest shield volcano on Earth. A team of volcanologists and ocean explorers used several lines of evidence to determine P?h?honu, a volcano within the Papah?naumoku?kea Marine National Monument now holds this distinction.
Boeing X-37B to study impact of radiation and other space effects on seeds and other materialsThe US’s uncrewed X-37B military spaceplane is expected to launch from Cape Canaveral air force station, in Florida, on 16 May.The Boeing craft will be carried into orbit by a United Launch Alliance Atlas V rocket. This will be its sixth launch, and the first to be the responsibility of the...
Archaeological sites on the far southern shores of South Africa hold the world's richest records for the behavioral and cultural origins of our species. At this location, scientists have discovered the earliest evidence for symbolic behavior, complex pyrotechnology, projectile weapons and the first use of foods from the sea.
In a recently published study, researchers from the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology revealed the largest and hottest shield volcano on Earth. A team of volcanologists and ocean explorers used several lines of evidence to determine Pūhāhonu, a volcano within the Papahānaumokuākea Marine National Monument now holds this distinction.
We all carry around our own microbiome, a world of microorganisms that live on our skin and in our bodies, playing important roles in maintaining health as we interact with the rest of the world. Everywhere we go, our microbiome interacts with the microbiomes of new environments and of the people we meet (see Microbiology 101: Where People Go, Microbes Follow).
In a small pool nestled between two waterfalls in Hidalgo, Mexico, lives a population of hybrid fish—the result of many generations of interbreeding between highland and sheepshead swordtails. The lab of Molly Schumer, assistant professor of biology at Stanford University, has been collecting these fish for years to study the evolution of hybrids.
Canada's spy agencies are warning that Canadian intellectual property linked to the pandemic is a "valuable target" for state-sponsored actors — just a day after U.S. intelligence agencies raised the alarm about China-backed hacking of institutions and companies researching vaccines, treatments and tests for the...
A sandwich of molybdenum, sulfur and selenium turns out to be deliciously useful for detecting biomolecules.
For predators like wolves, cougars and snow leopards, a cow or sheep out to pasture may make for an easy and tasty meal. But when wild animals eat livestock, farmers face the traumatic loss of food or income, frequently sparking lethal conflicts between humans and their carnivorous neighbors.
It started with the front door.Adrian Gomez lives with his partner in Los Angeles, where their first few days of sheltering in place for the coronavirus pandemic proved uneventful. They worked remotely, baked, took a 2-mile walk each morning and refinished their porcelain kitchen sink. But then, one night, the doorknob began to rattle "vigorously," so loud he could hear it from across...
Scientists at the Stem Cell Research program at Boston Children's Hospital and Dana-Farber Cancer Institute/Harvard Medical School have devised a mouse model that lets researchers track every cell in the body, from the embryonic stage until adulthood. Using a "barcoding" technique and CRISPR gene editing technology, the model can identify different cell types as they emerge and what genes each is...

Three earthquakes in the Monterey Bay Area, occurring in 1838, 1890 and 1906, happened without a doubt on the San Andreas Fault, according to a new paper by a Portland State University researcher.
A new Cornell University study on bees, plants and landscapes in upstate New York sheds light on how bee pathogens spread, offering possible clues for what farmers could do to improve bee health.
Arctic sea ice helps keep Earth cool, as its bright surface reflects the Sun's energy back into space. Each year scientists use multiple satellites and data sets to track how much of the Arctic Ocean is covered in sea ice, but its thickness is harder to gauge. Initial results from NASA's new Ice Cloud and land Elevation Satellite-2 (ICESat-2) suggest that the sea ice has thinned by as much as 20%...
NASA's James Webb Space Telescope has been successfully folded and stowed into the same configuration it will have when loaded onto an Ariane 5 rocket for launch next year.
Nearly 50 years ago, Brown University physicist Michael Kosterlitz and his colleagues used the mathematics of topology—the study of how objects can be deformed by stretching or twisting but not tearing or breaking—to explain puzzling phase changes in certain types of matter. The work won Kosterlitz a share of the 2016 Nobel Prize in Physics and has led to the discovery of topological phenomena...
A new study revealed hundreds of new strong gravitational lensing candidates based on a deep dive into data. The study benefited from the winning machine-learning algorithm in an international science competition.
Crop modeling is essential for understanding how to secure the food supply as the planet adapts to climate change. Many current crop models focus on simulating crop growth and yield at the field scale, but lack genetic and physiological data, which may hamper accurate production and environmental impact assessment at larger scales.
Mammals known as scaly anteaters are natural hosts of coronaviruses, but are not likely the direct source of the recent outbreak in humans, according to a new study.
