| Life in the shallows becomes a trap for baby sharks Posted: 21 Jul 2020 03:45 PM PDT Baby reef sharks tolerate living in the sometimes-extreme environments of their nurseries -- but these habitats face an uncertain future which may leave newborn sharks 'trapped'. |
| Lab-made virus mimics COVID-19 virus Posted: 21 Jul 2020 01:24 PM PDT Researchers have created a virus in the lab that infects cells and interacts with antibodies just like the COVID-19 virus, but lacks the ability to cause severe disease. This safer virus makes it possible for scientists who do not have access to high-level biosafety facilities to join the effort to find drugs or vaccines for COVID-19. |
| Magnetic field of a spiral galaxy Posted: 21 Jul 2020 01:07 PM PDT A new image from the VLA dramatically reveals the extended magnetic field of a spiral galaxy seen edge-on from Earth. |
| Spider monkey groups as collective computers Posted: 21 Jul 2020 01:07 PM PDT New research shows that spider monkeys use collective computation to figure out the best way to find food. |
| New study takes closer look at how environment affects daily life of sloths Posted: 21 Jul 2020 08:47 AM PDT Scientists studying brown-throated three-toed sloths, where predators are extinct and food is more accessible, have found that the animals adapt to have a primarily diurnal, or daytime, schedule. |
| 'Lost' world's rediscovery is step towards finding habitable planets Posted: 21 Jul 2020 08:47 AM PDT The rediscovery of a lost planet could pave the way for the detection of a world within the habitable 'Goldilocks zone' in a distant solar system. |
| Autopsies reveal surprising cardiac changes in COVID-19 patients Posted: 21 Jul 2020 08:47 AM PDT A series of autopsies conducted by LSU Health New Orleans pathologists shows the damage to the hearts of COVID-19 patients is not the expected typical inflammation of the heart muscle associated with myocarditis, but rather a unique pattern of cell death in scattered individual heart muscle cells. |
| Lego builds anaesthesia skills according to new study Posted: 21 Jul 2020 08:47 AM PDT Lego could be used as a practical tool to train doctors in anaesthetic skills according to new research that has shown a simple task using the building bricks can help improve technical skills - a finding that could improve medical training and patient safety. |
| Droplet biosensing method opens the door for faster identification of COVID-19 Posted: 21 Jul 2020 08:47 AM PDT Researchers have developed an ultrasensitive biosensing method that could dramatically shorten the amount of time required to verify the presence of the COVID-19 virus in a sample. |
| Front-line physicians stressed and anxious at work and home Posted: 21 Jul 2020 05:42 AM PDT Amid the COVID-19 chaos in many hospitals, emergency medicine physicians in seven cities around the country experienced rising levels of anxiety and emotional exhaustion, regardless of the intensity of the local surge, according to a new analysis. |
| Spinal stimulators repurposed to restore touch in lost limb Posted: 21 Jul 2020 05:41 AM PDT Devices commonly implanted for chronic pain could expand patient access to prosthetic arms that ''feel.'' |
| 3D hand-sensing wristband signals future of wearable tech Posted: 20 Jul 2020 04:09 PM PDT In a potential breakthrough in wearable sensing technology, researchers have designed a wrist-mounted device that continuously tracks the entire human hand in 3D. |
| Powerful human-like hands create safer human-robotics interactions Posted: 20 Jul 2020 01:45 PM PDT A team of engineers designed and developed a novel humanoid hand that may be able to help human-robotic interactions. |
| Climate scientists increasingly ignore ecological role of indigenous peoples Posted: 20 Jul 2020 11:59 AM PDT In their zeal to promote the importance of climate change as an ecological driver, climate scientists increasingly are ignoring the profound role that indigenous peoples played in fire and vegetation dynamics, not only in the eastern United States but worldwide, according to researchers. |
| Changes in farming urgent to rescue biodiversity Posted: 20 Jul 2020 11:59 AM PDT Humans depend on farming for their survival but this activity takes up more than one-third of the world's landmass and endangers 62% of all threatened species. However, agricultural landscapes can support biodiversity. Scientists argue that agroecological principles should be integrated in the post-2020 Global Biodiversity Framework to be decided at the 15th Convention of the Parties (COP15). |
| Chinese phase 2 trial finds COVID-19 vaccine is safe and induces an immune response Posted: 20 Jul 2020 10:25 AM PDT A phase 2 randomized controlled trial of a recombinant adenovirus type-5-vectored COVID-19 vaccine (Ad5-vectored COVID-19 vaccine) was conducted in China in April 2020 and involved more than 500 people. The primary objective of the study was to evaluate the immune response and safety of the vaccine, and to determine the most suitable dose for a phase 3 trial. Phase 3 trials are needed to confirm whether the vaccine candidate effectively protects against SARS-CoV-2 infection. |
| Geoscientists glean data suggesting global climate changes increase river erosion rates Posted: 20 Jul 2020 08:23 AM PDT Using cosmogenic nuclide burial dating methods and optically stimulated luminescence dating, geoscientists establish ages for river deposits from the Yukon River basin that span key time periods of global climate change. |
| Geophysics: A first for a unique instrument Posted: 20 Jul 2020 08:22 AM PDT Geophysicists have measured Earth's spin and axis orientation with a novel ring laser, and provided the most precise determination of these parameters yet achieved by a ground-based instrument without the need for stellar range finding. |
| Cheese making relies on milk proteins to form structure Posted: 20 Jul 2020 08:22 AM PDT Cheese production relies on coagulation of milk proteins into a gel matrix after addition of rennet. Milk that does not coagulate (NC) under optimal conditions affects the manufacturing process, requiring a longer processing time and lowering the cheese yield, which, in turn, has economic impact. Scientists studied the protein composition of milk samples with different coagulation properties to learn more about why only some milk coagulates with rennet. |
| Posted: 20 Jul 2020 08:22 AM PDT A phase 1/2 trial involving 1,077 healthy adults found that the vaccine induced strong antibody and T cell immune responses up to day 56 of the ongoing trial. These responses may be even greater after a second dose, according to a sub-group study of 10 participants. Compared to the control group (given a meningitis vaccine), the SARS-CoV-2 vaccine caused minor side effects more frequently, but some of these could be reduced by taking paracetamol. There were no serious adverse events from the vaccine. Based on their results, the authors say that further clinical studies, including in older adults, should be done with this vaccine. The current results focus on the immune response measured in the laboratory, and further testing is needed to confirm whether the vaccine effectively protects against infection. |
| Using techniques from astrophysics, researchers can forecast drought up to ten weeks ahead Posted: 20 Jul 2020 07:45 AM PDT Researchers have developed a system which can accurately predict a period of drought in East Africa up to ten weeks ahead. |
| Arizona rock core sheds light on Triassic dark ages Posted: 20 Jul 2020 07:20 AM PDT A rock core from Petrified Forest National Park, Arizona, has given scientists a powerful new tool to understand how catastrophic events shaped Earth's ecosystems before the rise of the dinosaurs. The core offers scientists a foundation to explain the changes in the fossil record and determine how these events may have shaped life on Earth. |
| Posted: 20 Jul 2020 07:17 AM PDT According to paleoclimatic reconstructions analyzing stalagmites sampled in some caves in the Murge plateau (Apulia, Italy), Neanderthals might have become extinct because Homo sapiens employed more sophisticated hunting technologies. |
