| Posted: 12 Jul 2022 11:12 AM PDT Purple sea urchins are munching their way through California's kelp forests at a speed and scale that have stunned scientists, fishermen and divers alike. But the kelp forests have long been home to red and purple urchins, so it's clear the three species can get along. Researchers sought to determine what factors disrupt this harmony. |
| Scientists identify mechanism responsible for fruit and seed development in flowering plants Posted: 12 Jul 2022 07:27 AM PDT Scientists identified a gene responsible for triggering plants to develop fruits and seeds. This finding may help agriculturists bypass pollination altogether for food production, which will be beneficial in these times of rising global temperatures and dwindling pollinator populations. |
| Study analyzes hepatitis E virus exposure in Iberian lynxes Posted: 12 Jul 2022 07:27 AM PDT Research results indicate that the level of virus exposure is higher among captive lynxes than those in the wild. |
| How stressed-out plants produce their own aspirin Posted: 12 Jul 2022 07:26 AM PDT Plants protect themselves from environmental hazards like insects, drought and heat by producing salicylic acid, also known as aspirin. A new understanding of this process may help plants survive increasing stress caused by climate change. |
| Habitat shifts affect brain structure in Amazonian butterflies Posted: 12 Jul 2022 07:26 AM PDT Habitat differences help determine changes in the nervous system of tropical butterflies, scientists have found. |
| Entombed together: Rare fossil flower and parasitic wasp make for amber artwork Posted: 11 Jul 2022 03:23 PM PDT Fossil research has revealed an exquisite merger of art and science: a long-stemmed flower of a newly described plant species encased in a 30-million-year-old tomb together with a parasitic wasp. |
| The best offense is a great defense for some carnivorous plants Posted: 11 Jul 2022 01:31 PM PDT Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Now,scientists have investigated the molecular basis of plant carnivory and found evidence that it evolved from mechanisms plants use to defend themselves. |
| Posted: 11 Jul 2022 01:31 PM PDT The amount of carbon stored by microscopic plankton will increase in the coming century, predict researchers. |
| X-rays help researchers piece together treasured cellular gateway Posted: 11 Jul 2022 01:31 PM PDT After almost two decades of synchrotron experiments, scientists have captured a clear picture of a cell's nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell's nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions. |
| Proof Mendel discovered the laws of inheritance decades ahead of his time Posted: 11 Jul 2022 11:32 AM PDT Gregor Mendel, the Moravian monk, was indeed 'decades ahead of his time and truly deserves the title of 'founder of genetics.'' So concludes an international team of scientists as the 200th birthday of Mendel approaches on 20 July. |
| Sperm are masters of DNA packing Posted: 11 Jul 2022 11:32 AM PDT During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. A central role is played by certain proteins around which the DNA thread is wrapped -- the protamines. A recent study provides new insights into this important mechanism. |
| Researchers capture images of antibody attacking neuron receptor Posted: 11 Jul 2022 10:53 AM PDT Researchers have captured images of an auto-antibody bound to a nerve cell surface receptor, revealing the physical mechanism behind a neurological autoimmune disease. The findings could lead to new ways to diagnose and treat autoimmune conditions, the study authors said. |
| Posted: 11 Jul 2022 10:53 AM PDT While more and more pathogens have developed biofilms that protect them from being eradicated by antibiotics, fewer classes of antibiotics are being developed. Researchers decided to go in a different direction and investigated a phytochemical derived from cruciferous vegetables such as broccoli that breaks down the biofilm. |
| Worms as model for personalized medicine Posted: 11 Jul 2022 10:53 AM PDT Using four unrelated strains of the microscopic nematode C. elegans originating from different parts of the world, a group of worm biologists have developed a model system to study individual differences in metabolism. This advancement represents a potentially important step toward 'personalized' or 'precision' medicine, a relatively new discipline that tailors dietary advice and disease treatment to an individual's own genome sequence. |
| Hidden genes may be tapped for new antibiotics Posted: 11 Jul 2022 10:53 AM PDT Bioscientists learn to trigger 'silent' gene clusters in bacteria that could be rich sources of new antibiotic candidates. |
| Bomb detectors picking up more blue whale songs in Indian Ocean Posted: 11 Jul 2022 08:18 AM PDT The good news is, pygmy blue whales appear to be thriving in the Indian Ocean. But not-so-good is that climate change may be threatening their food sources. |
