Horses were being ridden, worked, and traded long before anyone thought it possible. New research pushes back the accepted timeline of human use of horses by centuries, showing that humans used horses in organized ways as early as the 4th millennium BCE, if not earlier. The research is published(open access) in the journal Science Advances.

Rice plants and Venus flytraps share something in common that was not scientifically documented until recently. Using a faint smell to lure caterpillars into a trap, rice plants killed early-stage fall armyworm larvae by trapping them in a spikelet, the part at the end of a rice panicle where individual grains develop.

Salmon are becoming river “ghosts” as brutal droughts and violent floods cause unprecedented losses on their treacherous journey to the Pacific Ocean, scientists say. A study led by the University of Essex; NOAA Fisheries; University of California, Davis; and Cramer Fish Sciences has found that young Californian Chinook salmon face a deadly double threat from extreme weather and the destruction of historical wetland habitats they rely on.

…Ammonia is a tempting fuel for the world’s hottest jobs. It can be made from air, water and renewable electricity, stored as a liquid and shipped using know-how industry already has.

For decades, coral reefs throughout the Caribbean have been suffering from disease, pollution, overfishing and rising sea temperatures, yet most have continued to grow—until now.

The Timor green pigeon, which is under pressure from hunting and habitat loss, is at serious risk of extinction and should be uplisted to Critically Endangered, according to a new study from researchers at Charles Darwin University and BirdLife International.

Not many scientific studies sound like a Bond film, but ours really does involve lasers, sharks and doctors (of research, not the evil kind).

“What’s fascinating is that this process can become a self-reinforcing loop,” says Suvrajit Ghosh, a geology and geophysics Ph.D. student at Missouri S&T. “Rising sea levels can trigger carbon release, and that release can further accelerate changes that lead to even more sea-level rise.”

Crucially, this increase in fire activity is at odds with evidence from mainland Australia. Over the same 2,000-year period, fire activity in southeastern Australia was actually lower. This suggests the importance of Indigenous stewardship in suppressing bushfires, even when contending with the impacts of a drying climate overall.

Abstract: The exact origin of bread wheat (Triticum aestivum) is still a mystery, but researchers believe they are edging closer to the source of one of the most important food staples worldwide. Using genetic studies and ancient plant remains, an international team of scientists has narrowed the location and timeline to the Neolithic period(around 8,000 years ago) in Georgia, in the South Caucasus. They present their findings in a paper published in the journal Proceedings of the National Academy of Sciences.

A new study led by University of British Columbia researchers has found that pet cats allowed to roam outside unsupervised carry infectious diseases at rates comparable to feral cats, even when they receive veterinary care, regular meals, and shelter.

According to the Climate and Clean Air Coalition, anthropogenic methane emissions account for nearly 45% of current net warming, making it an important factor in global warming

Pooling data from more than 4,900 European-flagged bottom trawlers—together spending more than 5.5 million hours fishing on average each year in the waters of the European Union, the UK, Norway and Iceland—the research demonstrates that atmospheric carbon dioxide (CO2) emissions from disturbed seafloor sediments are a major contributor to these costs. The study concludes that the net costs of bottom trawling to society are 90 times greater than the €180 million in profits raked in by the fishing industry each year.

Brazil’s conversion of native biomes to farmland has generated an estimated soil carbon debt of 1.4 billion tonnes — equivalent to 5.2 billion tonnes of CO₂ — based on 30 years of data compiled from 4,290 records across 372 studies covering all Brazilian biomes.

While other species including gibbons and long-tailed macaques have also been spotted crossing there, “this is a world first for Sumatran orangutans,”

Still, Erisman warns against focusing only on “green” production. “We mainly see ammonia as a climate-friendly fuel for ships, as it does not produce CO₂ emissions,” he says. “But during use, ammonia can leak into soil, water, or air, and burning it releases nitrous oxide and nitrogen oxides.”

Studies indicate that the lack of human hunting, agriculture and development has a more positive impact on animal numbers than radiation has a negative one.
