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.

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.

Scientists have developed a new computational approach to create artificial proteins, which showed promising results in vivo as functional vaccines. This approach opens the possibility to engineer safer and more effective vaccines.

Researchers have long known that all of the millions of malaria parasites within an infected person's body move through their cell cycle at the same time. They multiply in sync inside red blood cells, then burst out in unison every few days. But how the parasites keep time was unclear. Now, a study finds that malaria has its own internal clock that causes thousands of genes to ramp up and down at...

The parasite that causes malaria has its own internal clock, explaining the disease's rhythmic fevers and opening new pathways for therapeutics.

A newly identified 'metabolic signature' can evaluate an individual's adherence and metabolic response to the Mediterranean diet and help predict future risk of developing cardiovascular disease.

Research has given new insight into the cause of mutations in pluripotent stem cells and potential ways of stopping these mutations from occurring.

A new electronic tagging study of 100 Potomac River striped bass sheds light on rockfish migration in Chesapeake Bay and the Atlantic Coast. Researchers found that when rockfish reach 32 inches in length they leave Chesapeake Bay and become ocean migrators. Small fish stayed in the Bay had higher mortality rates than those that undertook ocean migrations.

Researchers, politicians and funding bodies find themselves in front of a unique situation: The mounting pressure to accelerate and intensify efforts to tackle the COVID-19 pandemic while handling the growing threat from all other diseases endangering our society. This balancing and how well the scientific community will respond to it will define health across the globe for years to come, argue...

Scientists have used a lightweight eye-tracking system composed of miniature video cameras and motion sensors to record head and eye movements in mice without restricting movement or behavior. Measurements were made while the animals performed naturalistic visual behaviors including social interactions with other mice and visual object tracking.

As COVID-19 continues its sweep around the globe, dialysis units have continued to be hotspots for the virus' spread. Researchers hope to combat that threat, through a novel study that used antibody testing on patients, doctors, nurses and staff within the unit to track symptomatic and asymptomatic spread in a confined space.

Prior to the COVID-19 pandemic, in cities where bike-share systems have been introduced, bike commuting increased by 20%, according to a new study.

Oxidative stress can be pathological. Now researchers report that the other end of the redox spectrum, reductive stress, is also pathological. Reductive stress causes pathological heart enlargement and diastolic dysfunction in a mouse model.

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 article.

A research team has predicted the presence of 'topologically protected' electromagnetic waves that propagate on the surface of plasmas, which may help in designing new plasma systems like fusion reactors.

Arctic sea ice helps keep Earth cool, as its bright surface reflects the Sun's energy back into space.

Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still debated. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city's rapid...
