| 'Once-in-a generation' tardigrade fossil discovery reveals new species in 16-million-year-old amber Posted: 05 Oct 2021 04:10 PM PDT They've famously survived the vacuum of space, and even returned to life after being frozen for decades in Antarctic moss. But as hard as it is to kill the bizarre microscopic animal, the tardigrade, it's harder to find one fossilized. In fact, only two have ever been discovered and formally named -- until now. |

| Weed goes off script to resist herbicides Posted: 05 Oct 2021 02:53 PM PDT Cementing waterhemp's reputation as a hard-to-kill weed in corn and soybean production systems, researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized. |
| New measurement method promises spectacular insights into the interior of planets Posted: 05 Oct 2021 09:48 AM PDT At the heart of planets, extreme states are to be found: temperatures of thousands of degrees, pressures a million times greater than atmospheric pressure. They can therefore only be explored directly to a limited extent -- which is why the expert community is trying to use sophisticated experiments to recreate equivalent extreme conditions. Researchers have adapted an established measurement method to these extreme conditions and tested it successfully: Using the light flashes of the world's strongest X-ray laser the team managed to take a closer look at the important element, carbon, along with its chemical properties. |
| Gene linked to evolution of limb development identified Posted: 05 Oct 2021 09:48 AM PDT A new study gives insight into how limb development evolved in vertebrates. The findings identify a gene that plays a central role in the evolution of limb development in vertebrates. By manipulating this gene in mice, researchers were able to activate an ancestral form of limb development seen in early tetrapods (four-legged vertebrates). |
| Growing potential for toxic algal blooms in the Alaskan Arctic Posted: 05 Oct 2021 09:47 AM PDT Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon -- widespread blooms of toxic algae -- could become more commonplace, potentially threatening a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms (HABs) of the toxic algae Alexandrium catenella. |
| Smuggling light through opaque materials Posted: 05 Oct 2021 09:47 AM PDT Electrical engineers have discovered that changing the physical shape of a class of materials commonly used in electronics can extend their use into the visible and ultraviolet parts of the electromagnetic spectrum. Already commercially used in detectors, lenses and optical fibers, chalcogenide glasses may now find a home in applications such as underwater communications, environmental monitoring and biological imaging. |
| Simultaneous optical and electrical tracking of heart activity Posted: 05 Oct 2021 09:47 AM PDT It is still elusive to what extent interactions between different cell types of the heart influence the normal heart rhythm and possibly trigger life-threatening arrhythmias. A new measurement method combines optical and electrical recording of cardiac ventricular activation which, in conjunction with optogenetics, will permit finding comprehensive answers to these questions. |
| Posted: 05 Oct 2021 09:47 AM PDT Researchers developed a fully-integrated robotic arm that fuses visual data from a camera and radio frequency (RF) information from an antenna to find and retrieve object, even when they are buried under a pile and fully out of view. |

| Spider silk’s supposed 'healing properties' might have no basis in science Posted: 05 Oct 2021 09:47 AM PDT As far back as ancient Rome, spider silk has been used as a remedy to treat everything from skin lesions to warts. In the past, doctors have covered open wounds in cobwebs or advised patients to place cocoons on infected teeth. In modern times, however, the literature contains conflicting reports of whether or not spider silk has antimicrobial properties. Researchers have now revisited these old experiments and debunk the myth of antibiotic spider silk. |
| New study uncovers brain circuits that control fear responses Posted: 05 Oct 2021 09:47 AM PDT Researchers have discovered a brain mechanism that enables mice to override their instincts based on previous experience. |
| Worm mothers provide milk for their young Posted: 05 Oct 2021 09:47 AM PDT As worm mothers age, they secrete a milk-like fluid through their vulva that is consumed by their offspring and supports their growth, according to a new study. |
| Super-enhancers: The villain fueling certain cancers Posted: 05 Oct 2021 09:47 AM PDT Researchers identified a small RNA molecule called miR-766-5p that reduces expression of MYC, a critical cancer-promoting gene. This microRNA reduces levels of proteins CBP and BRD4, which are both involved in super-enhancer (SE) formation. SEs form in areas of DNA that can fuel MYC expression and tumor progression. This study provides strong evidence for developing miR-766-5p as a novel therapeutic to treat MYC-driven cancers. |
| Cancer chemotherapy drug reverses Alzheimer’s symptoms in mice Posted: 05 Oct 2021 09:46 AM PDT A drug commonly used to treat cancer can restore memory and cognitive function in mice that display symptoms of Alzheimer's disease, new research has found. The drug, Axitinib, inhibits growth of new blood vessels in the brain -- a feature shared by both cancer tumors and Alzheimer's disease. This hallmark represents a new target for Alzheimer's therapies. Mice that underwent the therapy not only exhibited a reduction in blood vessels and other Alzheimer's markers in their brains, they also performed remarkably well in tests designed to measure learning and memory. |
| Posted: 05 Oct 2021 09:46 AM PDT Sense of smell or taste returns within six months for 4 out of every 5 COVID-19 survivors who have lost these senses, and those under 40 are more likely to recover these senses than older adults, an ongoing study found. |
| Extreme exoplanet even more exotic than originally thought Posted: 05 Oct 2021 09:46 AM PDT Considered an ultra-hot Jupiter -- a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain -- the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists had realized. |
| Long-lasting pain relief without opioids: Novel, local treatment for chronic pain Posted: 05 Oct 2021 09:46 AM PDT An investigation into the origins of the sensation of pain has led to the development of a novel and durable treatment for inflammatory pain that could be a promising alternative to opioids. |
| Mitigating lung damage, mortality due to SARS-CoV-2 Posted: 05 Oct 2021 07:19 AM PDT Researchers report that a drug approved for treating patients with autoimmune disease helped to prevent lung damage and death in mice infected with the SARS-CoV-2 virus, which causes COVID-19 in humans. |
