In a world getting used to extreme weather, 2023 is starting out more bonkers than ever and meteorologists are saying it's natural weather weirdness with a bit of help from human-caused climate change.

A new study finds that foreign interference in an American election can reduce faith abroad in the United States as an effective and trustworthy ally, suggesting that Russia's meddling in the 2016 election had some international ramifications.
Custom sneakers, vintage dishware, a limited-edition car—each is an example of a product owners may regard as special and irreplaceable, fostering strong feelings of attachment.
Although most early dinosaurs were vegetarian, there were surprising differences in the way that these animals tackled eating a plant-based diet, according to a new study by scientists from the Natural History Museum and the Universities of Bristol and Birmingham.
One of Florida's largest passenger rail services is experiencing an increase in ridership—and leaders of a Florida Department of Transportation program that promotes alternatives to commuters who drive alone attribute some of this success to guidance from an interdisciplinary team of researchers at USF who combined eye-tracking technology and social marketing to improve the impact of marketing...
Climate-driven heating of seawater is causing a slowdown of deep circulation patterns in the Atlantic and Southern oceans, according to Earth system scientists at the University of California, Irvine, and if this process continues, the ocean's ability to remove carbon dioxide from the atmosphere will be severely limited, further exacerbating global warming.
Saffron (Crocus sativus) is a geophyte perennial plant from the family Iridaceae with underground soft corms. The stigmas of the saffron flower have been cultivated as a spice for at least 3,500 years. Conventional cultivation processes, such as planting, flower harvesting, and separation of the stigmas, are labor-intensive and time-consuming. The labor costs and low supply contribute to the high...
A new peer-reviewed study, which analyzes Florida housing markets battered by hurricanes, finds that affected areas tend to gentrify slightly in the years following a storm: The average income of new buyers increases while long-term demand stays stable.
A warming climate will increase the number of tropical cyclones and their intensity in the North Atlantic, potentially creating more and stronger hurricanes, according to simulations using a high-resolution, global climate model.
They've been pushed to the brink of extinction by dams, drought, extreme heat and even the flare of wildfires, but now California's endangered winter-run Chinook salmon appear to be facing an entirely new threat—their own ravenous hunger for anchovies.
Environmental contaminants like fluoride, lead and pesticides exist all around and even within us. While researchers have simple ways to measure concentrations of such contaminants inside lab environments, levels are much more difficult to test in the field. That's because they require costly specialized equipment.
Chemists from Rice University and the University of Texas at Austin discovered more isn't always better when it comes to packing charge-acceptor molecules on the surface of semiconducting nanocrystals.
Data published Wednesday by a respected environmental think tank indicates Germany likely missed its target for reducing greenhouse gas emissions again last year, despite a big effort by the new government to expand the renewable energy use.
An international study led by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) stresses the need to apply a biocultural approach in nature conservation programs.
Researchers from Oklahoma State University and University of Florida published a new article explaining how marketers can capitalize on the power of perception through the structure of visual communications to influence beliefs about brand performance, which ultimately influences product interest and choice.
The first chromosome level genome sequences for great hammerhead and shortfin mako sharks have shown that both species have experienced major population declines over a 250,000-year history. Low genetic diversity and signs of inbreeding are concerning for Critically Endangered great hammerhead sharks, whose overfished populations have plummeted. With higher levels of genetic diversity, shortfin...
Orangutans, mice, and horses are covered with it, but humans aren't. Why we have significantly less body hair than most other mammals has long remained a mystery. But a first-of-its-kind comparison of genetic codes from 62 animals is beginning to tell the story of how people—and other mammals—lost their locks.
Geminiviruses are a group of single-stranded circular plant DNA viruses that cause devastating diseases in many economically important crops including tomato, tobacco, cotton, corn, wheat, beans, and cassava worldwide. Due to their small genome size and limited coding capacity, geminiviruses rely heavily on host plants to complete their life cycle by exploiting/manipulating host components at...
Meat has multiple nutritional benefits and is consumed as the primary source of protein by an increasing segment of the world's population. However, there have been significant environmental costs associated with the growing demand for meat. The Food and Agriculture Organization of the United Nations (FAO) reported in 2013 that livestock production accounts for 14.5% of all greenhouse gas...
This study examines the state changes of nutrients (nitrogen, phosphorus and silicon) from one of the ten largest river systems in the world, the Changjiang, based on field expeditions and time-series data since early 1980s. The study covers an area of ~80% of the whole drainage basin (i.e., 1.8×106 km2) and 70% of water course, including main streams and 15 major tributaries.
An international team of scientists painstakingly gathered data from more than 50 years of seagoing scientific drilling missions to conduct a first-of-its-kind study of organic carbon that falls to the bottom of the ocean and gets drawn deep inside the planet.
Global warming is expected to lead to an accumulation of particularly intense hurricanes in the United States. This may substantially increase the economic losses caused by these storms. Better insurance could effectively mitigate the climate change-induced increase in economic losses. This is shown in a new study by the Potsdam Institute for Climate Impact Research examining the effectiveness of...
The Seebeck effect is a thermoelectric phenomenon by which a voltage or current is generated when a temperature difference exists across a conductor. This effect is the basis of established and emerging thermoelectric applications alike, such as heat-to-electricity energy harvesters, sensing devices, and temperature control.
A team of researchers from the Max Planck Institute for Intelligent Systems, Friedrich-Schiller-University, and the Georgia Institute of Technology has found that contrary to prior research results, dogs do not use their tails to help stabilize their movements. Instead, as they explain in their paper posted on the arXiv preprint, the tails are used as a communications device.
During embryonic development, two different cascades of genetic signals determine whether the embryo's primordial gonad will become testes or ovaries, and thus whether the embryo will develop into a male or a female. Disruptions in this process cause disorders in sexual development characterized by a mismatch between sex-determining chromosomes, gonads (ovaries or testicles) and the anatomy of the...
