When humans began farming crops thousands of years ago, agriculture had already been around for millions of years. In fact, several animal lineages have been growing their own food since long before humans evolved as a species. According to a new study, colonies of ants began farming fungi when an asteroid struck Earth 66 million years ago. This impact caused a global mass extinction but also created ideal conditions for fungi to thrive. Innovative ants began cultivating the fungi, creating [...]

Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors. Summary: Share: Low-calorie diets and intermittent fasting have been shown to have numerous health benefits: They can delay the onset of some age-related diseases and lengthen lifespan, not only in humans but many other [...]

In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight schistosomiasis, a widespread and debilitating parasitic disease. Now, researchers have developed models that can predict how the disease risk will shift in response to environmental changes. In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight a widespread and debilitating parasitic disease. Now, a partnership between researchers from Stanford [...]

Only a fraction of nature's diversity, or species richness, is still known, especially when it comes to insects and fungi, both of which have millions of species still unknown to science. At the same time, the loss of nature is progressing at an unprecedented rate, and researchers are racing against time to find out the unknown diversity while also coming up with ways to save it. "Air is a real treasure trove for nature research," says Academy Research Fellow Nerea Abrego from [...]

Most of us are aware that climate change is altering our world. But it can also make certain natural disasters, like hurricanes, more likely in places where susceptible species reside. Until recently, we had limited knowledge about which species are especially at risk due to natural hazards. Now, researchers from the Globe Institute at the University of Copenhagen have identified them, and the researchers behind the study, emphasize the urgent need for action based on their [...]

Date: April 16, 2024 Source: University at Buffalo Summary: A new study charts the family history of Arabica, the world's most popular coffee species, through Earth's heating and cooling periods over the last millennia. The key to growing coffee plants that can better resist climate change in the decades to come may lie in the ancient past. Researchers co-led by the University at Buffalo have created what they say is the highest quality reference genome to date of [...]

Many new drugs inhibit the processes that cancer cells need to divide rapidly. So as to inhibit the cancer as a whole. But cancer cells have all sorts of workarounds to get around that effect. As a result, the tumor becomes unresponsive to treatment. That’s why researcher Matheus dos Santos Dias is taking a completely different approach. He had to convince some colleagues before he could start working on this quite surprising idea. After all, you’re not going to give cancer cells [...]

Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows. Summary: Share: Some plant species will "win" and others will "lose" as global warming forces them to move uphill, new research shows. Scientists examined the current range of more than 7,000 plant species in Brazil's Cerrado savanna, and estimated shifts based on warming by 2040. The fate of plant species will depend on [...]
