| Quantum information theory: Quantum complexity grows linearly for an exponentially long time Posted: 28 Mar 2022 12:06 PM PDT Physicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems -- for example, black holes and wormholes in the universe. Now, researchers have proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge. |
| Spirituality can improve quality of life for heart failure patients, study finds Posted: 28 Mar 2022 11:10 AM PDT Numerous studies have shown that spirituality can help improve quality of life for people with chronic diseases like cancer. According to a literature review, spirituality can also have a positive impact on quality of life for heart failure patients. |
| Black patients with cancer fare worse with COVID-19, study shows Posted: 28 Mar 2022 10:38 AM PDT Lack of access to health care, social determinants of health, preexisting comorbidities and reduced access to clinical research are common to both cancer and COVID-19 in Black individuals. Together these two diseases create a perfect storm in this population, a new study indicates. |
| Posted: 28 Mar 2022 10:38 AM PDT In a potential paradigm change for sepsis diagnostics, a new test predicted sepsis soon after infection in mice -- well before blood clotting and organ failure -- enabling early antibiotic treatment and markedly increased survival. The findings provide a platform to develop rapid and easy-to-perform clinical tests for early sepsis detection and clinical intervention in human patients. |
| Squid skin-inspired cup cozy will keep your hands cool and your coffee hot Posted: 28 Mar 2022 10:37 AM PDT Drawing inspiration from cephalopod skin, engineers have invented an adaptive fabric that can be used to insulate the contents of coffee cups, to-go boxes and containers of almost any size. In a new paper, the researchers describe the manufacturing process they developed which enables economical mass production of their novel material. |
| Unprecedented videos show RNA switching ‘on’ and ‘off’ Posted: 28 Mar 2022 10:36 AM PDT Using new simulations, researchers discovered one part of RNA smoothly invades and displaces another part of the same RNA, enabling the structure to rapidly and dramatically change shape. Called strand displacement, this mechanism appears to switch genetic expression from 'on' to 'off'. |
| New nasal spray treats Delta variant infection in mice, indicating broad spectrum results Posted: 28 Mar 2022 10:36 AM PDT Researchers have shown a new compound delivered in a nasal spray is highly effective in preventing and treating COVID-19 caused by the Delta variant in mice. The researchers believe this is the first treatment of its kind proven to be effective against all COVID-19 variants of concern reported to date, including alpha, beta, gamma and delta. |
| Ancient helium leaking from core offers clues to Earth's formation Posted: 28 Mar 2022 10:36 AM PDT Helium-3, a rare isotope of helium gas, is leaking out of Earth's core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a solar nebula, which has long been debated. |
| Identifying risk factors following ICH strokes Posted: 28 Mar 2022 09:13 AM PDT Researchers reveal new insights into how different risk factors following intracerebral hemorrhages can affect patient outcomes. |
| The surprising diversity of the fallopian tube Posted: 28 Mar 2022 08:27 AM PDT A new study creates a detailed 'atlas' of the various cell types and their gene activities within the highly specialized fallopian tube, paving the way for new research into infertility and other diseases affecting this organ, including some cancers. |
| Posted: 28 Mar 2022 08:27 AM PDT Researchers have found that receiving a COVID-19 vaccine during pregnancy does not lead to increases in the frequency of complications around the time of childbirth. The findings provide further assurances about the safety of mRNA vaccines for this particularly unique population. |
| Marmoset monkeys solve hearing tests on the touchscreen Posted: 28 Mar 2022 08:26 AM PDT Researchers have developed an automated auditory training program that marmoset monkeys can perform in their familiar environment on a voluntary basis. The team has accomplished getting non-human primates to complete a series of tests in which they hear different sounds and then match them to the appropriate, previously learned visual stimuli by clicking on a touchscreen. This allows scientists to track which sounds the animals can hear and discriminate. |
| Brain waves reveal the active nature of engaging with art Posted: 28 Mar 2022 07:13 AM PDT A new study suggests that aesthetic experience goes hand in hand with both actively constructing meaning from an artwork and being in a state of heightened attention. |
| Chaos theory provides hints for controlling the weather Posted: 28 Mar 2022 07:13 AM PDT Researchers have used computer simulations to show that weather phenomena such as sudden downpours could potentially be modified by making small adjustments to certain variables in the weather system. They did this by taking advantage of a system known as a 'butterfly attractor' in chaos theory, where a system can have one of two states -- like the wings of a butterfly -- and that it switches back and forth between the two states depending on small changes in certain conditions. |
| Less antibody diversity as we age Posted: 28 Mar 2022 06:21 AM PDT As we age, our immune system works less well. We become more susceptible to infections and vaccinations no longer work as effectively. A research team has investigated whether short-lived killifish also undergo aging of the immune system. Indeed, they found that as early as four months of age, killifish have less diverse circulating antibodies compared to younger fish, which may contribute to a generalized decrease in the immune function. |
| Mysterious death of carbon star plays out like six-ring circus Posted: 28 Mar 2022 06:20 AM PDT Scientists studying V Hydrae (V Hya) have witnessed the star's mysterious death throes in unprecedented detail. The team discovered six slowly-expanding rings and two hourglass-shaped structures caused by the high-speed ejection of matter out into space. |
| Scientists discover body's natural alarm to battle blood loss Posted: 28 Mar 2022 06:20 AM PDT Fresh insights into how the body responds to blood loss could lead to a new treatment for traumatic injuries. |
| Potential therapy may boost chemoimmunotherapy response in bladder cancer Posted: 28 Mar 2022 06:00 AM PDT Adding an anti-inflammatory medication to immunotherapy and standard chemotherapy drugs may provide long-term suppression of aggressive bladder tumor growth, according to a proof-of-concept study. |
| Octopus-like tentacles help cancer cells invade the body Posted: 28 Mar 2022 06:00 AM PDT With help from the best tweezers in the world a team of researchers has shed new light on a fundamental mechanism in all living cells that helps them explore their surroundings and even invade tissue. Their discovery could have implications for research into cancer, neurological disorders and much else. |
| Scientists find that the impact of social media on wellbeing varies across adolescence Posted: 28 Mar 2022 06:00 AM PDT Girls and boys might be more vulnerable to the negative effects of social media use at different times during their adolescence, say an international team of scientists. The researchers show that, in UK data, girls experience a negative link between social media use and life satisfaction when they are 11-13 years old and boys when they are 14-15 years old. Increased social media use again predicts lower life satisfaction at age 19 years. At other times the link was not statistically significant. |
