A researcher reports evidence of a gall-forming aphid defending itself against predators, a first for the species, Mordwilkoja vagabunda. The insects inject saliva into leaf stalks, inducing the plant to form small growths called galls that the aphids live inside.
New research suggests high levels of dietary cholesterol make mice sicker when infected with influenza. This study links cholesterol in the diet with exacerbation of a viral infection.
Labels like indica, sativa and hybrid—commonly used to distinguish one category of cannabis from another—tell consumers little about what's in their product, and could be confusing or misleading, suggests a new study of nearly 90,000 samples across six states.
An international study provides the first global evaluation of all terrestrial vertebrate species that have not been declared extinct and identifies more than 500 species considered to be "lost"—those that haven't been seen by anyone in more than 50 years.
A new University of Michigan study that forecasts the impacts of expanding roads and a planned railway on endangered tigers in Nepal's Chitwan National Park has yielded important findings that can aid conservation efforts.
Using the eyes and ears of public volunteers can stretch the reach of science, according to a new analysis from Erica Stuber from the Department of Wildland Resources and the Ecology Center. Stuber and a team of researchers examined the accuracy of information produced by citizen science apps for monitoring bird populations. They compared publicly-produced data with officially tracked numbers from...
Newly developed flexible, porous and highly sensitive nitrogen dioxide sensors that can be applied to skin and clothing have potential applications in health care, environmental health monitoring and military use, according to researchers.
Production of animal protein in China has increased by 800% over the past 40 years, driven by population growth, urbanization and higher worker wages. However, the amount of climate-warming nitrous oxide released from animal farming in the country has not risen as quickly, thanks to science-led policy and farm management interventions in the way animals are fed and their manure recycled.
Teaching the benefits of affirmative sexual consent while also validating anxieties people might experience about consent communication is an important step for improving sexual health and well-being, according to a new study.
A trio of researchers at Virginia Commonwealth University has identified five types of daily workplace experiences that influence employees' creative performance.
Coats and scarves have come out prematurely in Brazil, as the south of the tropical country experiences a record-breaking cold spell, a menace for both homeless people and crops.
Male pheromones just might be the fountain of youth for aging female animals' eggs, according to a new Northwestern University study.
Leicester researchers searching for a "golden spike" to formally define humanity's current geological period—and acknowledge human impact on our planet—have announced a major step in their analysis at an international conference on Wednesday.
A family of proteins that have a role in ensuring many types of cells move and maintain their shape may promote disease when they act like workaholics and disrupt the cellular environment, new research suggests.
The high content of nitrogen-containing organic compounds (NOCs) in biocrude obtained from hydrothermal liquefaction of microalgae is one of the most concerning issues on the applications and environment. The biocrude obtained by hydrothermal liquefaction (HTL) needs further refining optimization, and the high concentration of nitrogen-heterocyclic compounds such as quinoline, pyridine, etc., will...
Engineers have developed a low cost, low power technology to help robots accurately map their way indoors, even in poor lighting and without recognizable landmarks or features. The technology uses WiFi signals, instead of light, to help the robot 'see' where it's going.
Some 1.7 million Americans each year acquire hospital infections, resulting in nearly 100,000 deaths from infection-related complications. The biggest culprits: medical devices like catheters, stents and heart valves, whose surfaces often become covered with harmful bacterial films. A novel surface treatment developed by a UCLA-led team of scientists stops microbes from adhering to medical...
