| Cancer cells can migrate toward certain 'sweet spot' environments Posted: 12 Jul 2022 12:50 PM PDT Engineers have discovered that cancer cells invade the body based on their environment. The discovery provides new understanding of how cancer spreads and can improve future treatments. |
| Efficient, stable, and eco-friendly thermoelectric material discovered Posted: 12 Jul 2022 11:14 AM PDT A thermoelectric metal oxide film with a thermoelectric figure of merit of ~0.55 at 600°C has been discovered, opening new avenues towards the widespread use of thermoelectric converters. |
| Nutrient imbalance in flathead lake Posted: 12 Jul 2022 11:14 AM PDT New research has found a sustained imbalance between nitrogen and phosphorus that likely has significant ecological consequences for lakes worldwide. |
| Research links national-level greenhouse gas emissions, warming and resulting economic damage Posted: 12 Jul 2022 11:13 AM PDT Study provides data on gains and losses attributable to individual countries, including the finding that a group from the world's leading national emitters of GHGs have caused $6 trillion in global economic losses through warming caused by their emissions from 1990 to 2014. |
| Successful heart xenotransplant experiments set protocol for pig-to-human organ transplantation Posted: 12 Jul 2022 11:13 AM PDT A team successfully transplanted two genetically engineered pig hearts into recently deceased humans in June and July, marking the latest advances toward addressing the nationwide organ shortage and developing a clinical protocol that would provide an alternative supply of organs for people with life-threatening heart disease. |
| Soil quality critical to help some U.S. crops weather heat stress from climate change Posted: 12 Jul 2022 11:13 AM PDT The results singled out growing-degree days as the most important climatic factor and water holding capacity as the most influential soil property for crop-yield variability. |
| Posted: 12 Jul 2022 11:13 AM PDT Researchers have found a new, dynamic protein structure in cells. |
| Spirituality linked with better health outcomes, patient care Posted: 12 Jul 2022 11:13 AM PDT The study is the most rigorous and comprehensive analysis to date of scientific literature on health and spirituality. Overlooking spirituality in health care leaves patients feeling disconnected from the health care system and from the clinicians caring for them. Asking about a patient's spirituality should be part of patient-centered, value-sensitive care, new research suggests. |
| Space rocket junk could have deadly consequences unless governments act Posted: 12 Jul 2022 11:13 AM PDT The re-entry of abandoned stages of rockets left in orbit from space launches have a six to 10 per cent chance of severely injuring or killing a human being in the next decade, according to a new study. Researchers say governments need to take collective action and mandate that rocket stages are guided safely back to Earth after their use, which could increase the cost of a launch, but potentially save lives. |
| 3D printing nickel single crystals using laser additive manufacturing technology Posted: 12 Jul 2022 11:12 AM PDT Engineers have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius, flat-top laser beam (i.e., a laser beam whose intensity is uniform across a cross-section of the beam). This technique may be used to fabricate a wide variety of single-crystalline materials, including heat-resistant materials for jet engines and gas turbines. |
| Shift work increases the severity of strokes later in life Posted: 12 Jul 2022 11:12 AM PDT As most Americans wind down for bed, 15 million people are just clocking into work. These hospital workers, emergency responders, factory operators and others are among the 20 percent of the world's population who do shift work. Their different sleep-wake cycle elevates their risk for numerous health disorders, including diabetes, heart attacks, cancer and strokes. |
| Protein folding in times of oxygen deficiency Posted: 12 Jul 2022 11:12 AM PDT Protein molecules require a defined shape in order to function. When they are created, their building blocks are therefore linked together in a very specific way. Researchers are now taking a closer look at a key step in this process and are investigating the effects of transient oxygen starvation on protein folding in plants. |
| Posted: 12 Jul 2022 11:12 AM PDT New research reveals that two different white blood cell types influence cardiac arrhythmia, suggesting that treatments that influence these cells may help reduce patients' risk of sudden cardiac death. |
| Experience required: A role for vision in the development of inhibitory networks Posted: 12 Jul 2022 11:12 AM PDT New research demonstrates that inhibitory and excitatory neuronal circuits of the visual system develop through different processes, even if the organization of the mature circuit is similar. These findings highlight the importance of the continued study of the development of these two systems, the understanding of which is fundamental to comprehending neurodevelopmental disorders. |
| How do cells react to micro- and nanoplastics? Posted: 12 Jul 2022 07:27 AM PDT The smaller plastic particles are, the more easily they can be taken up by cells. In addition, the shape, surface and chemical properties play an important role in answering the question of how the particles could affect human tissue, according to new research. |
| New research provides insight into Long COVID and ME Posted: 12 Jul 2022 07:27 AM PDT Researchers have uncovered how post-viral fatigue syndromes, including Long COVID, become life-changing diseases and why patients suffer frequent relapses. |
| Intensive telephone-based cessation counseling results in improved smoking quit rates Posted: 12 Jul 2022 07:27 AM PDT Offering intensive, weekly telephone-based cessation counseling along with nicotine replacement for people who smoke and who were undergoing screening for lung cancer resulted in over a two-fold greater cigarette quit rate compared to people who received minimal counseling and nicotine replacement, according to results of a national, randomized trial. |
| Study analyzes hepatitis E virus exposure in Iberian lynxes Posted: 12 Jul 2022 07:27 AM PDT Research results indicate that the level of virus exposure is higher among captive lynxes than those in the wild. |
| Posted: 12 Jul 2022 07:26 AM PDT New research may provide a key to a scientific enigma: How does the awake brain transform sensory input into a conscious experience? The groundbreaking study relied on data collected from electrodes implanted, for medical purposes, deep in the human brain. The information was utilized to examine differences between the response of the cerebral cortex to sounds in sleep vs. wakefulness, at a resolution of single neurons. |
| Economic inequality and instability impact long-term decision-making around the world, study finds Posted: 12 Jul 2022 07:26 AM PDT A large study involving more than 60 countries finds that individuals across income groups and locations often prefer immediate gains at the expense of future gains, a phenomenon known as temporal discounting. However, greater individual economic resources and living in a stable and more equal economy make the behavior less likely. |
| Entombed together: Rare fossil flower and parasitic wasp make for amber artwork Posted: 11 Jul 2022 03:23 PM PDT Fossil research has revealed an exquisite merger of art and science: a long-stemmed flower of a newly described plant species encased in a 30-million-year-old tomb together with a parasitic wasp. |
| The four bases of anti-science beliefs -- and what to do about them Posted: 11 Jul 2022 01:31 PM PDT The same four factors that explain how people change their beliefs on a variety of issues can account for the recent rise in anti-science attitudes, a new review suggests. |
| Sperm are masters of DNA packing Posted: 11 Jul 2022 11:32 AM PDT During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. A central role is played by certain proteins around which the DNA thread is wrapped -- the protamines. A recent study provides new insights into this important mechanism. |
| Posted: 11 Jul 2022 10:53 AM PDT While more and more pathogens have developed biofilms that protect them from being eradicated by antibiotics, fewer classes of antibiotics are being developed. Researchers decided to go in a different direction and investigated a phytochemical derived from cruciferous vegetables such as broccoli that breaks down the biofilm. |
