Small, low-cost sensors developed by space scientists at The University of Texas at Dallas to study the Earth's upper atmosphere recently—and unexpectedly—provided information about the sun, something the devices were not designed to do.
A study reported in the journal acta ethologica has recorded the use of ultrasound by amphibians for the first time in South America. It also describes the first documented case of the use of ultrasound for defense against predators, in a distress call of ear-piercing intensity to many animals, but inaudible to humans.
The booming use of electric vehicles in parts of California is reducing CO2 emissions in those areas, a study showed Thursday, bolstering a key pillar of the state's drive towards net zero.
After two decades in the United States, Martin Hetzer returned home to Austria in 2023 to become the 2nd President of the Institute of Science and Technology Austria (ISTA). A year into his new role, the molecular biologist remains engaged in the realm of aging research.
The historic Paris climate agreement started a mantra from developing countries: "1.5 to stay alive." It refers to the international aim to keep global warming under 1.5 degrees Celsius (2.8 Fahrenheit) compared with preindustrial times. But the world will likely pass that threshold within a decade, and global warming is showing little sign of slowing.
Just 57 companies and nation states were responsible for generating 80% of the world's CO₂ emissions from fossil fuels and cement over the last seven years, according to a new report released by the thinktank InfluenceMap. This finding suggests that net zero targets set by the Paris climate change agreement in 2015 are yet to make a significant impact on fossil fuel production.
The vast majority of the EU's agricultural subsidies are supporting meat and dairy farming rather than sustainable plant alternatives. That's the key finding of our new research, published in Nature Food, in which for the first time we were able to fully account for crops and other plants grown to feed animals.
For almost 15 years, scientists have debated whether the Anthropocene should be an official geological epoch marking the profound influence of humans on the planet. Then in March, an international panel of scientists formally rejected the proposal for a new Anthropocene epoch.
Earth was long thought to be the only planet in our solar system with an ocean, but it is beginning to look as though there are underground oceans inside even the most surprising icy bodies.
Trigger warning: this article contains accounts of sexual violence.
Kenya once had an exceptional abundance and diversity of wildlife. But as the country's population boomed, wildlife lost space to people, buildings, roads and agriculture.
The Osun River is one of the major rivers in southern Nigeria. It flows from its source in Ekiti State, through several states, before emptying into Lagos state's Lekki Lagoon. It is an important source of water for the communities that live around it, whether for irrigation or for personal use.
We have no good reason to believe that aliens have ever contacted Earth. Sure, there are conspiracy theories and some rather strange reports about harm to cattle, but nothing credible. Physicist Enrico Fermi found this odd. His formulation of the puzzle, proposed in the 1950s and now known as "the Fermi Paradox", is still key to the search for extraterrestrial life (SETI) and messaging by sending signals into space (METI).
Since the start of this year, the price for cocoa traded on the futures exchange has doubled, climbing from US$4,275 a ton to US$9,481 after earlier hitting an all-time high of US$10,274.
Changing weather patterns induced by climate change are contributing to shifts in the location of terrorist activity, according to new research.
An extensive CO2 monitoring network set up around the San Francisco Bay Area by an atmospheric chemist from the University of California, Berkeley, has recorded the first evidence that the adoption of electric vehicles is measurably lowering the area's carbon emissions. The findings have been published in the journal Environmental Science & Technology.
Early in May 2023, a small team of marine biologists arrived in the Saudi Arabian city of Jeddah. They'd flown into the local airport from Guam, the United States, Portugal, Spain and Japan, and they'd soon rendezvous with colleagues from the King Abdullah University of Science and Technology (KAUST), a research university built along the banks of the Red Sea.
After the introduction of the income tax in the United States, there has been a migration of higher income earners toward states with lower or no income tax, a new study reveals.
Amid the aftermath of heightened xenophobia and racism toward Asian Americans during the COVID-19 pandemic, faculty from the University of Hawaiʻi at Mānoa Thompson School of Social Work & Public Health exposed the challenges and resilience of these communities in three publications.
While a dominant personality can help you climb the corporate ladder, new research shows there is also a "humble route" to career advancement.
Recent decades have witnessed rapid changes in the Arctic climate, with warming rates surpassing global averages by three to four times. This puzzling "Warm Arctic, Cold Eurasia" climate phenomenon has profound implications, sparking scientific curiosity into its underlying mechanisms.
The world is a cluttered, noisy place, and the ability to effectively focus is a valuable skill. For example, at a bustling party, the clatter of cutlery, the conversations, the music, the scratching of your shirt tag and almost everything else must fade into the background for you to focus on finding familiar faces or giving the person next to you your undivided attention.
Scientists may one day be using a new technique to potentially pick up and record key airborne forensic DNA evidence from crime scenes wiped clean of fingerprints and other trace evidence.
Fire is an important part of plant life in Australia, influencing where plants grow and how abundant a species will be.
Western North America seems to be experiencing more extreme weather events more frequently. From scorching droughts to torrential floods, the climate is changing rapidly, with no signs of slowing down. From 2011 to 2015, California and neighboring states experienced extended periods of drought, while 2017 saw heavy rains trigger catastrophic floods.
