| Bedtime linked with heart health Posted: 08 Nov 2021 04:36 PM PST Going to sleep between 10:00 and 11:00 pm is associated with a lower risk of developing heart disease compared to earlier or later bedtimes, according to a new study. |
| Blood plasma protein fibrinogen interacts directly with nerve cells to cause brain inflammation Posted: 08 Nov 2021 01:22 PM PST Before soluble fibrinogen, a blood plasma protein, is converted into insoluble fibrin molecules that can toxically accumulate outside blood vessels in the brain, fibrinogen connects directly with neurons and can cause a damaging inflammatory reaction, a research team reports. Their discovery may help identify new therapeutic targets for neurodegenerative diseases such as Alzheimer's disease and traumatic brain injury. |
| New study pinpoints likely path of COVID-related plastic waste in the ocean Posted: 08 Nov 2021 01:14 PM PST Researchers use a new model to project where the surge of mismanaged medical waste will end up—including beaches, seabeds, and the Arctic Ocean. |
| A new tool for studying COVID's impact on gut health Posted: 08 Nov 2021 10:09 AM PST New research using an Intestine Chip has recreated viral infection of the human gut in vitro using a coronavirus called NL63, which causes the common cold and is also associated with GI symptoms. |
| Posted: 08 Nov 2021 10:09 AM PST Combining the immunotherapy agent durvalumab with the chemotherapy agents pemetrexed and cisplatin or carboplatin may provide a new treatment option for patients who have inoperable pleural mesothelioma, a cancer of the tissues lining the lungs, according to a phase II clinical trial. |
| Study offers insights on why the elderly are more susceptible to COVID-19 Posted: 08 Nov 2021 10:08 AM PST New research reveals the cellular mechanism behind why the elderly, as well as those with certain overlapping diseases, are at risk of infection and death from the virus -- and how this mechanism can potentially be used to protect them. |
| Stem cells do not (only) play dice Posted: 08 Nov 2021 10:08 AM PST In just a few weeks a completely new organism develops from a fertilized egg cell. The real miracle is that a bunch of identical stem cells turns into completely different, specialized cell types. A team has now been able to show that the specialization of individual cells during embryonic development is not, as previously assumed, exclusively left to chance but is rather determined by cell communication. |
| Air pollution disproportionally affects people of color, lower-income residents in DC Posted: 08 Nov 2021 10:02 AM PST The rates of death and health burdens associated with air pollution are borne unequally and inequitably by people of color and those with lower household income and educational attainment in Washington, D.C., according to a new study. The study found that while deaths and health burdens associated with PM2.5 halved between 2000 and 2018 in the D.C. area, disparities and geographical segregations in health effects persist. |
| Storing energy in plants with electronic roots Posted: 08 Nov 2021 08:48 AM PST By watering bean plants (Phaseolus vulgaris) with a solution that contains conjugated oligomers, researchers at the Laboratory of Organic Electronics, Linköping University, Sweden, have shown that the roots of the plant become electrically conducting and can store energy. |
| Sitting more linked to increased feelings of depression, anxiety Posted: 08 Nov 2021 08:48 AM PST During the initial COVID-19 outbreak in March 2020, a lot of people suddenly became more sedentary as they adhered to stay-at-home orders or opted to self-isolate. Recently published research found people who continued to spend a higher amount of time sitting in the weeks following were likely to have higher symptoms of depression. A closer investigation into this association could play a role in helping people improve their mental health. |
| Galectin-1 linked to increased risk of type 2 diabetes Posted: 08 Nov 2021 06:42 AM PST Researchers now associate elevated levels of the protein galectin-1 with increased risk of developing type 2 diabetes about 18 years later. At the same time, this protein seems to be a protective factor for the kidneys among type 2 diabetes patients at high risk for diabetic nephropathy. |
| Healing skin ischemia-reperfusion injuries with interleukin-36 receptor antagonists Posted: 08 Nov 2021 06:42 AM PST Skin wounds from ischemia-reperfusion injuries -- tissue damage caused by blood returning to tissues after a period of oxygen deprivation -- may not heal appropriately in some patients, owing to elusive underlying immunological mechanisms. Scientists from Japan have now succeeded in proposing a means to solve this medical conundrum by understanding the role of interleukin-36 receptor antagonists as they act to inhibit the effects of interleukin-36 cytokines, which could help identify new therapeutic targets for wound healing. |
| High cell membrane tension constrains the spread of cancer Posted: 08 Nov 2021 06:42 AM PST The membranes of cancer cells are more pliant than the membranes of normal cells. A research collaboration has discovered that cancer invasion and migration can be supressed in mice by manipulating the stiffness of the cell membrane. Hopefully this will contribute towards the development of new treatments that target the physical characteristics of cancer cells. |
| Despite understanding the concept of mindfulness, people are applying it incorrectly, research finds Posted: 08 Nov 2021 05:16 AM PST Mindful awareness is about both accepting and engaging with life's challenges, and that's what popularized concepts of mindfulness tend to miss, new research has found. |
| New symptoms identified that could help doctors diagnose pancreatic cancer Posted: 08 Nov 2021 05:16 AM PST Researchers have identified a series of symptoms associated with pancreatic cancer, including two previously unrecognised symptoms -- feeling thirsty and having dark urine. |
| COVID-19: The older you are, the more antibodies you have, study finds Posted: 08 Nov 2021 05:14 AM PST Chemists looked at lab samples of patients who recovered from a mild case of COVID-19 and found that those over 50 produced more antibodies against the SARS-CoV-2 virus. |
| Flame retardants linked to autistic-like behavior, research finds Posted: 07 Nov 2021 06:59 PM PST Researchers have found that when female mice exposed to PBDEs pass on these neuroendocrine-disrupting chemicals to their developing offspring, the female offspring show traits relevant to autism spectrum disorders. |
| Bone marrow backup needed to tackle respiratory infections Posted: 06 Nov 2021 09:58 AM PDT Scientists have found how the immune system triggers an 'emergency' dendritic cell response during infection, with dendritic cells at the site of infection being reinforced by new cells which travel from the bone marrow. |
| Posted: 05 Nov 2021 07:37 AM PDT A landmark study of more than 18,000 Americans and Australians over 70 years of age reveals that 3.5 to 7 average drinks of alcohol a week is more protective against heart disease and in fact all-cause mortality - compared to those who drank no alcohol. |
| Increased frequency of eating eggs in infancy associated with decreased egg allergy later on Posted: 05 Nov 2021 05:41 AM PDT A new study suggests that early egg introduction is associated with decreased egg allergy. |
| Sweat-collecting patch inspired by cactus spines Posted: 04 Nov 2021 07:06 AM PDT Engineers have developed a sweat-collecting patch inspired by cactus spines. The patch readily performs body fluid analysis of sweat sensor when attached to the body and is readily applicable in wearable healthcare devices. |
