| Here comes the Sun: Planetary scientists find evidence of solar-driven change on the Moon Posted: 21 Aug 2021 08:39 AM PDT A new study uncovered important clues to help understand the surprisingly active lunar surface. The scientists found that solar radiation could be a more important source of lunar iron nanoparticles than previously thought. |
| Posted: 21 Aug 2021 08:39 AM PDT Scientists have transferred a technique from one realm of plasma physics to another to enable the more efficient design of powerful magnets for doughnut-shaped fusion facilities known as tokamaks. |
| Researchers develop novel strategy for tuberculosis vaccine Posted: 21 Aug 2021 08:38 AM PDT Innovators have created a novel strategy for developing an effective vaccine for a widespread form of tuberculosis. |
| Under the northern lights: Mesospheric ozone layer depletion explained Posted: 21 Aug 2021 08:38 AM PDT The same phenomenon that causes aurorae -- the magical curtains of green light often visible from the polar regions of the Earth -- causes mesospheric ozone layer depletion, which could have significance for global climate change. Now, a group of scientists has observed, analyzed, and provided greater insight into this phenomenon. |
| PULSAR-integrated radiotherapy with immunotherapy for improved tumor control Posted: 21 Aug 2021 08:38 AM PDT Cancer physicians are pioneering a new PULSAR radiation-therapy strategy that improves tumor control compared with traditional daily therapy. |
| Opening a path toward quantum computing in real-world conditions Posted: 20 Aug 2021 12:37 PM PDT The quantum computing market is projected to reach $65 billion by 2030, a hot topic for investors and scientists alike because of its potential to solve incomprehensibly complex problems. Drug discovery is one example. To understand drug interactions, a pharmaceutical company might want to simulate the interaction of two molecules. The challenge is that each molecule is composed of a few hundred atoms, and scientists must model all the ways in which these atoms might array themselves when their respective molecules are introduced. The number of possible configurations more than the number of atoms in the entire universe. Only a quantum computer can represent, much less solve, such an expansive, dynamic data problem. |
| Using artificial intelligence for early detection and treatment of illnesses Posted: 20 Aug 2021 10:53 AM PDT Artificial intelligence (AI) will fundamentally change medicine and healthcare: Diagnostic patient data, e.g. from ECG, EEG or X-ray images, can be analyzed with the help of machine learning, so that diseases can be detected at a very early stage based on subtle changes. However, implanting AI within the human body is still a major technical challenge. Scientists have now succeeded in developing a bio-compatible implantable AI platform that classifies in real time healthy and pathological patterns in biological signals such as heartbeats. It detects pathological changes even without medical supervision. |
| Distress signal from fat cells prompts heart to shore up defenses against consequences of obesity Posted: 20 Aug 2021 10:53 AM PDT A stress signal received by the heart from fat could help protect against cardiac damage induced by obesity, a new study suggests. The finding could help explain the 'obesity paradox,' a phenomenon in which obese individuals have better short- and medium-term cardiovascular disease prognoses compared with those who are lean, but with ultimately worse long-term outcomes. |
| Polymer electrolytes for all-solid-state batteries without dead zones Posted: 20 Aug 2021 08:10 AM PDT A joint research team succeeds in improving ionic conductivity using electrostatic interface of polymer electrolytes. |
| New breakthrough in research into old insect exoskeletons Posted: 20 Aug 2021 08:10 AM PDT Researchers have isolated genetic material from exuviae (discarded exoskeletons) left after insects like cicadas molt. The researchers tested five different methods of amplifying the DNA sample by PCR, and were able to isolate nuclear DNA of good enough quality for repetitive loci known as microsatellites to be genotyped. This work is a significant contribution to insect sciences because these methods can be used for any insect species that molts. |
| New insights on mechanism that could help treat muscle-related diseases Posted: 19 Aug 2021 04:51 PM PDT Expression of the MyoD gene combined with exposure to three chemicals causes skin cells to become primitive muscle progenitors that can be maintained indefinitely in the lab and later coaxed into becoming mature muscle cells to treat muscle-related diseases. Skin-derived muscle progenitors are molecularly similar to muscle tissue stem cells, and muscle cells derived from these progenitors are more stable and mature than muscle cells directly converted from skin cells. |
| Dynamic photosynthesis model simulates 10-20 percent yield increase Posted: 19 Aug 2021 11:27 AM PDT A team has developed a model that treats photosynthesis as a dynamic process rather than an activity that either is or is not happening. This allowed the group to examine the impacts of the many fluctuations in light that crop leaves experience due to intermittent clouds, overlying leaves, and the sun's daily passage across the sky. |
| Hydraulic fracturing can impact surface water quality, study suggests Posted: 19 Aug 2021 11:27 AM PDT The estimated impact on water quality is more pronounced during the period when wells generate large amounts of flowback and produced water, and where water monitors are closest to wells. More data is needed to better understand the full extent of the impact. |
