| 'Double-hazard' zones for wildfire in the West Posted: 07 Feb 2022 12:56 PM PST Rapidly growing communities in the American West's forests and shrublands are nestled in zones where local soil and plant traits amplify the effect of climate change on wildfire hazards and lead to bigger burns. |
| How do pathogens learn to be pathogens? Partnerships between microbes leading to human disease Posted: 07 Feb 2022 10:58 AM PST New research discovered that the fungus Rhizopus fights back against soil predators and human immune cells by partnering with a bacteria called Ralstonia in a two-way partnership. |
| In mice, mothers with metabolic syndrome can 'turn on' offspring’s liver disease Posted: 07 Feb 2022 09:48 AM PST An imprinted gene associated with development of non-alcoholic fatty liver disease (NAFLD) is switched on in mice who nurse from mothers with metabolic syndrome, even when those mice are not biologically related. |
| The frogs of Baja California: Scientists assess amphibian disease Posted: 07 Feb 2022 09:48 AM PST Biologists from Southern and Baja California have published the first major account of the amphibian disease chytridiomycosis in the Mediterranean region of Baja California. Their results indicate that the disease is more prevalent on the peninsula than in similar areas of Southern California. |
| Large new titanosaurian dinosaur from the Pyrenees Posted: 07 Feb 2022 09:48 AM PST Researchers have described the new species of titanosaur dinosaur Abditosaurus kuehnei from the remains excavated at the Orcau-1 site, in the southern Pyrenees (Catalonia, Spain). The semiarticulated 70.5-million-year-old skeleton is the most complete specimen of this herbivorous group of dinosaurs discovered so far in Europe. |
| New fossil reveals origin of arthropod breathing system Posted: 07 Feb 2022 09:46 AM PST Scientists have discovered a new fossil that reveals the origin of gills in arthropods. |
| Chimpanzee mother seen applying an insect to a wound on her son Posted: 07 Feb 2022 08:26 AM PST Researchers have observed chimpanzees in Gabon, West Africa applying insects to their wounds and the wounds of others. Scientists describe this wound-tending behavior and argue that it is evidence that chimpanzees have the capacity for prosocial behaviors that have been linked with empathy in humans. |
| Stressed out worms use epigenetic inheritance to produce more sexually attractive offspring Posted: 07 Feb 2022 08:24 AM PST Sexual reproduction allows organisms to mix up their genes and develop new adaptations to survive a harsh and ever-changing environment. Under nutrient-rich conditions, the worm C. elegans is typically asexual, but after enduring several generations of stress, the worms begin to reproduce sexually and release pheromones to appear more sexually attractive to male worms. |
| Shifting rainfall patterns will affect whether an imperiled butterfly survives climate change Posted: 07 Feb 2022 07:01 AM PST When we think of climate change, we often imagine how a warmer world will impact species, but a new study highlights the importance of changes in precipitation. The finding suggests that paying attention to the environmental triggers within each species' lifecycle will help us better understand how they will be affected by climate change. |
| The Congo tropical forest is simply different Posted: 07 Feb 2022 05:34 AM PST Until now, research assumed that the vast forest area of the Congo Basin, like other tropical forests, releases large amounts of nitrous oxide and binds methane. Researchers have now shown that it behaves differently: methane is released, while nitrous oxide emissions are smaller than thought. |
| New research bites holes into theories about Megalodons Posted: 07 Feb 2022 05:34 AM PST A new study leaves large tooth marks in previous conclusions about the body shape of the Megalodon, one of the largest sharks that ever lived. |
| Dog feces and urine could be harming nature reserves, according to new study Posted: 07 Feb 2022 05:34 AM PST New research finds that dogs being walked in nature reserves contribute a significant amount of nutrients to the environment through their feces and urine, which researchers warn could negatively impact local biodiversity. |
| Advanced prostate cancer antibody drug shows success in pet dogs Posted: 07 Feb 2022 05:34 AM PST Mice are typically used as models in advanced prostate cancer research, but the profound differences between them and humans has long bedeviled the translation of findings from the animal to success in people. Dogs however are the only other animal that suffers from a significant incidence of prostate cancer, and researchers are finding them much more enlightening subjects in identification of drugs that show promise for human patients. |
| Biologists investigate smallest propeller on Earth Posted: 07 Feb 2022 05:34 AM PST Scientists have discovered new information about the tiny propellers used by single-cell organisms called archaea. |
| Venomous Australian sea anemone may lead to life-saving drugs Posted: 06 Feb 2022 12:44 PM PST An entirely new toxic compound found in an Australian tropical sea anemone is being analysed as a potential new drug therapy, after it was discovered by biomolecular scientists during investigation of the species' multiple venoms. |
| Underwater 'breathing' plants could be key to stress-resistant crops Posted: 06 Feb 2022 12:44 PM PST Wetland plants have a high tolerance against flooding due to the formation of 'lysigenous aerenchyma,' air channels that help transfer gases to the submerged roots. These channels also help the plant withstand drought and nutrient deficiency. Now, scientists investigate the underlying mechanism of aerenchyma formation to understand the phenomenon better, opening doors to the development of crops that are resilient against extreme weather changes. |
| Japanese squirrels can consume 'poisonous' mushrooms Posted: 03 Feb 2022 07:30 AM PST Often featured in fairytales, the red toadstool mushroom fly agaric (Amanita muscaria) is toxic to humans and many animals. However, experts have observed that Japanese squirrels can safely eat 'poisonous' Amarita species, suggesting that there is a mutually beneficial relationship between squirrels and these fungi. |
