| Hostility linked with higher risk of death after second heart attacks Posted: 14 Sep 2020 04:40 PM PDT Heart attack patients who are sarcastic or irritable could be putting their health at risk. 'Hostility is a personality trait that includes being sarcastic, cynical, resentful, impatient or irritable.'      |
| Combining two precision medicines can treat drug-resistant cancers Posted: 14 Sep 2020 04:40 PM PDT Launching a dual-pronged attack on tumours using a combination of two innovative precision medicines could treat patients with multiple common cancers, a new clinical trial shows. |
| Human activities promote disease-spreading mosquitoes; more study needed for prevention Posted: 14 Sep 2020 02:29 PM PDT Disease-spreading mosquitoes may be more likely to occupy areas impacted by human activities like pesticide use and habitat destruction, than they are areas less disturbed by humans, a recent study found. |
| Virtual reality trains public to reverse opioid overdoses Posted: 14 Sep 2020 01:07 PM PDT The United States has seen a 200% increase in the rate of deaths by opioid overdose in the last 20 years. But many of these deaths were preventable. Naloxone, also called Narcan, is a prescription drug that reverses opioid overdoses, and in more than 40 states there is a standing order policy, which makes it available to anyone, without an individual prescription from a healthcare provider. |
| Immune system affects mind and body, study indicates Posted: 14 Sep 2020 10:19 AM PDT Researchers have discovered that a molecule produced by the immune system acts on the brain to change the behavior of mice. |
| Botox for TMJ disorders may not lead to bone loss in the short term, but more research is needed Posted: 14 Sep 2020 10:19 AM PDT Botox injections to manage jaw and facial pain do not result in clinically significant changes in jaw bone when used short term and in low doses, according to researchers. However, they found evidence of bone loss when higher doses were used. |
| Substance use disorders linked to COVID-19 susceptibility Posted: 14 Sep 2020 08:59 AM PDT A recent study found that people with substance use disorders (SUDs) are more susceptible to COVID-19 and its complications. The findings suggest that health care providers should closely monitor patients with SUDs and develop action plans to help shield them from infection and severe outcomes. |
| Excessive lung release of neutrophil DNA traps may explain severe complications in COVID-19 patients Posted: 14 Sep 2020 08:41 AM PDT Researchers have detected significant amounts of DNA traps in distinct compartments of the lungs of patients who died from Covid-19. These traps, called NETs, are released massively into the airways, the lung tissue and the blood vessels. Such excessive release could be a major contributor to severe disease complications leading to in-hospital death. |
| New X-ray microscopy technique enables comprehensive imaging of dense neural circuits Posted: 14 Sep 2020 08:41 AM PDT A new x-ray microscopy technique could help accelerate efforts to map neural circuits and ultimately the brain itself. Combined with artificial intelligence-driven image analysis, researchers used XNH to reconstruct dense neural circuits in 3D, comprehensively cataloging neurons and even tracing individual neurons from muscles to the central nervous system in fruit flies. |
| New treatments for deadly lung disease could be revealed by 3D modeling Posted: 14 Sep 2020 08:22 AM PDT A 3D bioengineered model of lung tissue is poking holes in decades worth of flat, Petri dish observations into how the deadly disease pulmonary fibrosis progresses. |
| DNA damage caused by migrating light energy Posted: 14 Sep 2020 08:22 AM PDT Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers have demonstrated that DNA damage may also occur far away from the point of incidence of the radiation. They produced an artificially modeled DNA sequence in new architecture and detected DNA damage at a distance of 30 DNA building blocks. |
| New study explores if flirting is real and shows it can work Posted: 14 Sep 2020 08:21 AM PDT Misunderstandings about flirting can potentially result in awkwardness or even accusations of sexual harassment. How can we figure out what other people mean when they smile at us? Is there a unique, identifiable facial expression representing flirting — and if there is, what does it convey, and how effective is it? |
| Fast and efficient method to produce red blood cells developed Posted: 14 Sep 2020 06:59 AM PDT Researchers have developed a faster and more efficient way to manufacture red blood cells that cuts down on cell culture time by half. The cells are frozen in liquid nitrogen and thawed on demand to produce matured RBCs in only 11 days, removing the need for continuous 23-day manufacturing. The team also designed complementary technology for more targeted cell sorting and purification. |
| Bioactive nano-capsules to hijack cell behavior Posted: 14 Sep 2020 06:59 AM PDT Many diseases are caused by defects in signaling pathways of body cells. In the future, bioactive nanocapsules could become a valuable tool for medicine to control these pathways. Researchers have taken an important step in this direction: They succeed in having several different nanocapsules work in tandem to amplify a natural signaling cascade and influence cell behavior. |
| Painless paper patch test for glucose levels uses microneedles Posted: 14 Sep 2020 06:58 AM PDT Researchers have developed a microneedle patch for monitoring glucose levels using a paper sensor. The device painlessly monitors fluid in the skin within seconds. Anyone can use the disposable patch without training, making it highly practical. Additionally, fabrication is easy, low cost, and the glucose sensor can be swapped for other paper-based sensors that monitor other important biomarkers. |
| Embryos taking shape via buckling Posted: 14 Sep 2020 06:58 AM PDT The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures. Although buckling could be the dominant mechanism that triggers invagination, it has never been possible of measuring the tiny forces involved. This gap has finally been filled. |
| Touch-and-know: Brain activity during tactile stimuli reveals hand preferences in people Posted: 14 Sep 2020 06:58 AM PDT Scientists show that it is possible to distinguish between left-handed and right-handed people by noninvasively monitoring just their brain activity during passive tactile stimulation. These results are key in haptic research (the study of sensory systems) and have various important implications for brain-computer interfaces, augmented reality, and even artificial intelligence. |
| TRESK regulates brain to track time using sunlight as its cue Posted: 14 Sep 2020 05:38 AM PDT Research has found that TRESK, a calcium regulated two-pore potassium channel, regulates the brain's central circadian clock to differentiate behavior between day and night. |
| Asthma patients given risky levels of steroid tablets Posted: 13 Sep 2020 01:29 PM PDT More than one quarter of asthma patients have been prescribed potentially dangerous amounts of steroid tablets, with researchers warning this puts them at greater risk of serious side-effects. |
