| Climate crisis drives Mediterranean coral populations to collapse Posted: 19 Jan 2022 09:13 AM PST A new study has revealed that marine heatwaves associated with the climate crisis are bringing down the populations of coral in the Mediterranean, the biomass of which in some cases has been reduced by 80 to 90%. |
| High protein diet may harm polar bears Posted: 19 Jan 2022 09:13 AM PST A high protein diet appears linked to kidney disease and shortened lifespans for captive polar bears, a relationship similarly suspected in humans. A careful look at what zoos have fed polar bears revealed they mostly offered a diet intended for big cats, containing about 2-3 parts protein to 1-part fat, a reversal from what was observed in the wild. |
| Smart windows can significantly reduce indoor pathogens Posted: 19 Jan 2022 09:13 AM PST Daylight passing through smart windows results in almost complete disinfection of surfaces within 24 hours while still blocking harmful ultraviolet (UV) light, according to new research. For this research, she tested four strains of hazardous bacteria -- methicillin-resistance Staphylococcus aureus, Klebsiella pneumoniae, E. coli and Pseudomonas aeruginosa -- using a mini-living lab set-up. The lab had smart windows, which tint dynamically based on outdoor conditions, and traditional windows with blinds. |
| Self-organization of complex structures: A matter of time Posted: 19 Jan 2022 09:13 AM PST Researchers have developed a new strategy for manufacturing nanoscale structures in a time- and resource-efficient manner. |
| Muscular study provides new information about how the largest dinosaurs moved and evolved Posted: 19 Jan 2022 09:13 AM PST New research has revealed how giant 50-ton sauropod dinosaurs, like Diplodocus, evolved from much smaller ancestors, like the wolf-sized Thecodontosaurus. |
| Internal ocean in small Saturn moon uncovered Posted: 19 Jan 2022 07:12 AM PST A scientist recently set out to prove that the tiny, innermost moon of Saturn was a frozen inert satellite and instead discovered compelling evidence that Mimas has a liquid internal ocean. In the waning days of NASA's Cassini mission, the spacecraft identified a curious libration, or oscillation, in the moon's rotation, which often points to a geologically active body able to support an internal ocean. |
| New tool assesses evolutionary risks of antibiotics Posted: 19 Jan 2022 06:09 AM PST Countering a rising antibiotic resistance crisis, doctors now prescribe combinations of antibiotics. Yet many risks are involved with such multi-drug combinations. Scientists have developed a way to help doctors evaluate outcomes for different drug pairs and boost the odds of successful treatment. |
| Heart function recovered quickly in children with COVID-19-related MIS-C condition Posted: 19 Jan 2022 06:08 AM PST Heart recovery began within the first week of diagnosis among children who developed COVID-19-related multisystem inflammatory syndrome (MIS-C), according to a new study. Children treated for MIS-C had normal heart function within three months after their first symptoms. The findings suggest children diagnosed with MIS-C may safely and gradually return to competitive sports after three months. |
| Scientists discover tarantula-killing worms Posted: 19 Jan 2022 06:08 AM PST Scientists have named a newly discovered species of worm that kills tarantulas after American actor Jeff Daniels, a distinction no other actor can claim. |
| Antifreeze cream prevents frostbite injuries to skin, study suggests Posted: 19 Jan 2022 06:08 AM PST Skiers, hikers, soldiers and others exposed to extreme cold temperatures can experience frostbite -- a painful injury that occurs when ice crystals form in the skin. Many extremely cold areas are also remote, and delays in frostbite treatment can result in severe wounds, scarring and even limb amputation. Now, researchers have developed a cream that prevents frostbite injuries in mice when applied to the skin 15 minutes before severe cold exposure. |
| Epilepsy research boosts case for new gene therapy for Dravet syndrome Posted: 19 Jan 2022 06:08 AM PST New research suggests how a newly developed gene therapy can treat Dravet syndrome, a severe form of epilepsy, and potentially prolong survival for people with the condition. |
| 3D robotic spine 'twin' and sensor offer new way to preview surgical interventions Posted: 19 Jan 2022 06:08 AM PST Researchers created a novel 3D printed robotic replica of a human spine modified to include an artificial disc implant with a soft magnetic sensor array to enable surgeons to preview the effects of surgical interventions prior to the operation. The patient-specific model was based on a CT scan of the human spine. Results showed that the soft magnetic sensor array system had the high capability to classify five different postures of the spine with 100 percent accuracy, which can be a predictor of different problems of the spine that people experience. |
| Astrocyte studies reveal harmful changes in amyotrophic lateral sclerosis Posted: 18 Jan 2022 05:35 PM PST Scientists have revealed harmful changes in supporting cells, called astrocytes, in amyotrophic lateral sclerosis (ALS). |
| Guiding the treatment of critically ill patients Posted: 18 Jan 2022 12:48 PM PST New research on intravenous fluids used in intensive care shows that commonly used saline is as effective at keeping people alive and their organs functioning as more expensive balanced solutions. |
