Floral scents play essential ecological roles, attracting pollinators and deterring herbivores. Geraniol, a monoterpene with a sweet, rose-like aroma, is a major commercial fragrance component widely used in the perfume and flavor industries. In most flowering plants, geraniol
As drug-resistant infections continue to rise, researchers are looking for new antimicrobial strategies that are both effective and sustainable. One emerging approach combines nanotechnology with "green" chemistry, using plant extracts instead of harsh chemicals to produce
The first-ever audited account of the actual amounts of CO2 stored underground by CCS projects globally has been released. It was created by a new international consortium of scientists and industrial partners, including NTNU.
At this point in history, astronomers and engineers who grew up watching "Deep Impact" and "Armageddon," two movies about the destructive power of asteroid impacts, are likely in relatively high ranking positions at space agencies. "Don't Look Up" also provided a more modern,
Most people interested in space exploration already know lunar dust is an absolute nightmare to deal with. We've already reported on numerous potential methods for dealing with it, from 3D printing landing pads so we don't sand blast everything in a given area when a rocket

Two pioneering studies by researchers from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv University, led by Dr. Omri Bronstein, have identified the primary drivers of sea urchin mass mortality events over recent decades: pathogens, storms, and
Despite the vast diversity of human languages, specific grammatical patterns appear again and again. A new study reveals that around a third of the long-proposed "linguistic universals"—patterns thought to hold across all languages—are statistically supported when examined with
A two-decade-long experiment in the Sierra Nevada found that regular prescribed burns promote carbon sequestration in live trees and plants, maintaining forests' long-term ability to store carbon while also reducing wildfire hazard.
Small changes in turnout could substantially alter election results in the future because the U.K. now has a multiparty system with majoritarian voting rules, warns a new study published in Parliamentary Affairs.

The Ngogo chimpanzees of Uganda's Kibale National Park have long been known for violent clashes with neighboring groups, often resulting in deaths—a phenomenon sometimes described as "chimpanzee warfare."
By studying more than 10,000 necropsies, researchers now know how much plastic it takes to kill seabirds, sea turtles, and marine mammals, and the lethal dose is much smaller than you might think. Their new study titled "A quantitative risk assessment framework for mortality
Public opinion polls and other surveys rely on data to understand human behavior. New research from Dartmouth reveals that artificial intelligence can now corrupt public opinion surveys at scale—passing every quality check, mimicking real humans, and manipulating results
A 12,000-year-old clay figurine unearthed in northern Israel, depicting a woman and a goose, is the earliest known human-animal interaction figurine. Found at the Late Natufian site of Nahal Ein Gev II, the piece predates the Neolithic and signals a turning point in artistic
Researchers Sumika Kato, Takeo Kubo, and Taro Fukazawa of the University of Tokyo have discovered that c1qtnf3, a secreting factor, namely a protein molecule that is secreted by a cell and influences functions of other cells, is expressed in putative muscle stem cells and
A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years earlier than previously thought.
One of the major realizations of the Anthropocene era has been the importance of biodiversity for the functioning of the Earth system, as well as for human societies.
A carefully crafted figure of a goose and a woman suggests that art reflecting spiritual beliefs entered a new phase among early villagers in the Middle East.
A single iron-sulfur building block directly determines whether ribosomes—the protein factories of our cells—work smoothly or not. This is the conclusion of a recent research project led by the RPTU Kaiserslautern-Landau. The findings significantly expand our understanding of
Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. Now, a study led by a team from the University of Gothenburg and published in Nature Communications provides a
Nitrogen is a bit of a conundrum. In its gaseous form it's the most abundant element in the atmosphere, but few organisms can readily use it. And while all living organisms contain nitrogen, a new University of Vermont study finds that even tiny amounts of nitrogen can fuel
A global analysis of coral bleaching across 81 countries reveals that reefs in the equatorial Coral Triangle region were exposed to the weakest marine heat waves over the past two decades and may function as safe havens for corals even as global warming robs the planet of most
A new international study co-led by the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment shows how a single genetic change helps protect corn seeds during storage. This offers plant breeders a clear target for developing varieties that stay
The Omo-Turkana Basin, where the Omo River drains into Lake Turkana in Africa, has been one of the three most valuable regions for the study of hominin evolution in Africa. Since the 1960s, many large-scale studies have taken place in the region and contributed to our

Polling on public attitudes to climate change show a dip in the numbers who worry about it in many high-income countries, compared with three years ago. This declining public concern will be a worry to those governments looking to push forward with new environmental measures.
The resignation of the BBC's director general and CEO of news is only the latest symptom of a deeper malaise in the media, a crisis of trust that runs through broadcasters and newspapers alike.
A new study shows that the effectiveness of current vaccines against porcine reproductive and respiratory syndrome virus (PRRSV) is due to the response of T cells against the disease, rather than the production of antibodies. The work is an important step in identifying
Two new studies from researchers at UC San Diego's Scripps Institution of Oceanography provide encouraging news about California's beaches at both local and statewide scales.

Behind the talk of fighting inequality at the group of 20 most powerful economies in the world, the G20, lies a carefully staged show—one that manages dissent rather than redistributes power.
What helps students from all walks of life have a good college experience?
Not long ago, the idea of getting paid to share your morning routine online would have sounded absurd. Yet today, influencers are big business: The global market is expected to surpass US$32 billion by the end of 2025.
Five years into Canada's $10-a-day child care plan, affordability has improved dramatically for families fortunate enough to have a space. However, the families who need care the most are being left behind.
'Tis the season for giving—and that means 'tis the season for shopping. Maybe you'll splurge on a Black Friday or Cyber Monday deal, thinking, "I'll just return it if they don't like it." But before you click "buy," it's worth knowing that many retailers have quietly tightened
