Researchers discover new reproductive method that will improve cattle production

Humans are not the only species negatively affected by increasingly hot and humid conditions. Intense heat waves sometimes kill large numbers of wild animals. Eastern Australia's giant fruit bats, known as flying-foxes, provide possibly the most dramatic illustration. In late 2018, two days of extreme heat in the far north of Queensland wiped out one third of Australia's population of spectacled flying-foxes. The species is now red-listed as endangered.

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 Scie

A new study, conducted by researchers from the Netherlands and Germany, estimates that urban agriculture in European cities could produce up to 20 million tons of vegetables annually, representing roughly one-third of the region's current vegetable production. The study, published in the journal Sustainable Cities and Society, systematically analyzes the potential of urban agriculture for 840 cities across 30 European countries.

Who should you target, and when, to maximize the impact of your message? New research uses mathematical models to show that targeted influence is significantly more effective than random persuasion. In social networks, certain individuals play a key role at specific moments in how ideas spread and how polarization arises.
