| Accelerating the discovery of new materials for 3D printing Posted: 15 Oct 2021 03:42 PM PDT A new data-driven system accelerates the process of discovering 3D printing materials that have multiple mechanical properties. |
| Key protein linked to appetite and obesity in mice Posted: 15 Oct 2021 10:32 AM PDT Researchers have identified a protein that plays a key role in how the brain regulates appetite and metabolism. Loss of the protein, XRN1, from the forebrain, resulted in obese mice with an insatiable appetite, according to a new study. |
| How to program DNA robots to poke and prod cell membranes Posted: 15 Oct 2021 08:12 AM PDT A discovery of how to build little blocks out of DNA and get them to stick to lipids has implications for biosensing and mRNA vaccines. |
| Discovery of new role for the brain’s immune cells could have Alzheimer's implications Posted: 15 Oct 2021 06:48 AM PDT The immune cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke, among other conditions linked to diseases of the brain's small vessels. |
| Contraceptive pill can reduce type 2 diabetes risk in women with polycystic ovary syndrome Posted: 15 Oct 2021 06:47 AM PDT A study has revealed for the first time that the contraceptive pill can reduce the risk of type 2 diabetes by over a quarter in women with polycystic ovary syndrome (PCOS). The research findings also show that women with PCOS have twice the risk of developing type 2 diabetes or pre-diabetes (dysglycemia) -- highlighting the urgent need to find treatments to reduce this risk. |
| Gel fights drug-resistant bacteria and induces body’s natural immune defense Posted: 14 Oct 2021 02:27 PM PDT In the fight against multidrug-resistant bacteria, scientists have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body's own immune responses to fight infections. |
| Study could pave way for creating safer opioids Posted: 14 Oct 2021 02:27 PM PDT Researchers may have an uncovered new answers on how to create safer opioids. Design a new opioid to bypass the part of brain that feels pleasure, but retain the analgesic properties, which make opioids one of the most effective pain relievers. Researchers looked at how opioids may have become so widely abused. |
| Posted: 14 Oct 2021 02:27 PM PDT Stem-like cells that make up only a tiny fraction of the total cells in a lung tumor could be the key to stopping the disease's deadly spread, say researchers. |
| Study discovers unique brain signature of intimate partner aggression Posted: 14 Oct 2021 11:19 AM PDT A new study used functional magnetic resonance imaging to examine the brain activity of 51 male-female romantic couples as they experienced intimate partner aggression in real time. They found that aggression toward intimate partners was associated with aberrant activity in the brain's medial prefrontal cortex, or MPFC, which has many functions, but among them is the ability to foster perceptions of closeness with and value of other people. |
| New technique helps researchers understand how acid damages teeth Posted: 14 Oct 2021 11:19 AM PDT Researchers have developed a new technique to improve understanding of how acid damages teeth at the microstructural level. |
| Posted: 14 Oct 2021 11:18 AM PDT Clinical decisions made in the delivery setting as to whether to employ vaginal delivery or cesarean section are often made under high pressure, and with great uncertainty, and have serious consequences for mother and baby. Now, a new study of electronic health records spanning 86,000 deliveries suggests that if their prior patient had complications in one delivery mode, a physician will be more likely to switch to the other -- and likely inappropriate -- delivery mode for the subsequent patient, regardless of whether it is warranted for that patient's indications. |
| Filling the gaps: Connecting genes to diseases through proteins Posted: 14 Oct 2021 11:18 AM PDT Hundreds of connections between different human diseases have been uncovered through their shared origin in our genome, challenging the categorization of diseases by organ, symptoms, or clinical specialty. A new study has generated data on thousands of proteins circulating in our blood and combined this with genetic data to produce a map showing how genetic differences that affect these proteins link together seemingly diverse as well as related diseases. |
| The gene behind an unusual form of Cushing’s Syndrome Posted: 14 Oct 2021 10:12 AM PDT The molecular causes of a particular type of food-dependent Cushing's Syndrome, a rare disease of the adrenal glands, are finally revealed. |
| Americans are eating more ultra-processed foods Posted: 14 Oct 2021 07:20 AM PDT Consumption of ultra-processed foods has increased over the past two decades across nearly all segments of the U.S. population, according to a new study. |
| Posted: 14 Oct 2021 07:01 AM PDT Scientists report that children benefited most from 60 hours of Constraint-Induced Movement Therapy (CIMT) over four weeks. The study also showed that the intensive therapy did not add stress for families. |
| Don’t go green with envy, but fish might be able to distinguish color more effectively than humans Posted: 13 Oct 2021 12:22 PM PDT Researchers have revealed that non-mammalian vertebrates might have a much more simple and effective way of deciphering between colour and greyscale information than humans, tracking explanations back to early evolution. |
