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.
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...
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...
Epoxides belong to a class of organic compounds called "cyclic ethers" that are characterized by a three-atom ring. They are readily available compounds found in medicinal and agrochemical agents, as well as natural products. Epoxides are a valuable industrial precursor as they allow the synthesis of a diverse range of important alcohols, functional polymers, agrochemicals, and pharmaceuticals...
American aerospace giant Boeing is making a third attempt to reach the International Space Station Thursday in a critical uncrewed test flight for its Starliner capsule, which has been beset by numerous failures and false starts.
The U.S. is on pace to recover all 22 million jobs wiped out in the COVID-19 recession as early as July, but the milestone will obscure sharp differences among industries and an economy transformed by the crisis.
In the days of cable TV, melancholy commercials pleading for donations to help save big animals on the brink of extinction—such as elephants, polar bears, gorillas, and pandas—landed on screens across the United States.
When President Joe Biden went to Capitol Hill in October to arm-twist for his signature environmental and economic legislation, many Democrats remained hopeful the bill's climate provisions would survive.
On a humid August afternoon in 2020, two caskets―one silver, one white―sat by holes in the ground at a small, graveside service in the town of Travelers Rest, South Carolina.
What will it take to make our electronics smarter, faster, and more resilient? One idea is to build them from materials that are topological.
An international team of scientists from UCL (University College London), the Swedish Museum of Natural History, Natural History Museum (London) and the University of Florence have found a remarkable type of fossilization that has remained almost entirely overlooked until now.
A critical goal in genetics and evolution is predicting the effects of mutations that may happen in the future and inferring the effects of those that happened in the past. To make these predictions, scientists generally assume that a mutation's effects tested in the present apply to past and future versions of the same gene.
How will future warming of the planet impact cold-water corals? A new analysis of ancient evidence from the last major global warming event identifies food and oxygen supply as key environmental factors that influence the vitality of cold-water corals in the North Atlantic Ocean and the Mediterranean Sea. Rodrigo da Costa Portilho-Ramos of the University of Bremen, Germany, and colleagues present...
When it comes to avian influenza, more commonly known as bird flu, all birds are not created equal.
