| How more inclusive lab meetings lead to better science Posted: 27 May 2021 12:01 PM PDT A new article seeks to help scientists structure their lab-group meetings so that they are more inclusive, more productive and, ultimately, lead to better science. |
| Three years younger in just eight weeks? A new study suggests yes! Posted: 27 May 2021 11:53 AM PDT A groundbreaking clinical trial shows we can reduce biological age (as measured by the Horvath 2013 DNAmAge clock) by more than three years in only eight weeks with diet and lifestyle through balancing DNA methylation. |
| Aging: Clinical trial on potential reversal of epigenetic age using a diet and lifestyle Posted: 27 May 2021 11:53 AM PDT A randomized controlled clinical trial was conducted among 43 healthy adult males between the ages of 50-72. The 8-week treatment program included diet, sleep, exercise and relaxation guidance, and supplemental probiotics and phytonutrients. |
| Microbial gene discovery could mean greater gut health Posted: 27 May 2021 11:52 AM PDT As the owner of a human body, you're carrying trillions of microbes with you everywhere you go. These microscopic organisms aren't just hitching a ride; many of them perform essential chemical reactions that regulate everything from our digestion to our immune system to our moods. |
| Fight against antibiotic-resistant bacteria has a glowing new weapon Posted: 27 May 2021 11:52 AM PDT In the perpetual arms races between bacteria and human-made antibiotics, there is a new tool to give human medicine the edge, in part by revealing bacterial weaknesses and potentially by leading to more targeted or new treatments for bacterial infections. |
| Posted: 27 May 2021 08:26 AM PDT About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a new study. |
| AGA recommends early use of biologics in patients with moderate-to-severe Crohn's disease Posted: 27 May 2021 08:25 AM PDT Crohn's disease, a type of inflammatory bowel disease (IBD) that causes inflammation (pain and swelling) in the gastrointestinal tract, can cause daily health problems, frequent hospitalizations and surgery when not adequately controlled. While there is no cure for Crohn's disease, there are treatments that can help patients live a symptom-free life. |
| New microscopy method reaches deeper into the living brain Posted: 27 May 2021 08:25 AM PDT Researchers have developed a new technique that allows microscopic fluorescence imaging at four times the depth limit imposed by light diffusion. Fluorescence microscopy is often used to image molecular and cellular details of the brain in animal models of various diseases but, until now, has been limited to small volumes and highly invasive procedures due to intense light scattering by the skin and skull. |
| Artificial neurons recognize biosignals in real time Posted: 27 May 2021 08:25 AM PDT Researchers have developed a compact, energy-efficient device made from artificial neurons that is capable of decoding brainwaves. The chip uses data recorded from the brainwaves of epilepsy patients to identify which regions of the brain cause epileptic seizures. This opens up new perspectives for treatment. |
| Mathematical model developed to prevent botulism Posted: 27 May 2021 08:24 AM PDT Food producers can use a mathematical model to ensure their products do not cause botulism. |
| New study confirms noble false widow spiders bites can result in hospitalization Posted: 27 May 2021 08:24 AM PDT Scientists have published a new study showing that Noble False Widow spiders can deliver a bite that requires hospitalization. The threat posed by the Noble False Widow spider has been debated among spider and healthcare specialists for many years. This new study confirms that some bite victims experience symptoms very similar to the true black widow spiders and some severe cases require hospitalization. |
| 'Rescue mutations' that suppress harmful DNA changes could shed light on genetic disorders Posted: 27 May 2021 08:24 AM PDT New insights into the ability of DNA to overcome harmful genetic changes have been discovered. |
| Sometimes, even 3-year-olds just want to fit in with the group Posted: 27 May 2021 08:24 AM PDT What makes preschoolers eat their veggies? Raise their hand? Wait their turn? 'Because I say so' is a common refrain for many parents. But when it comes to getting kids to behave, recent research suggests that the voice of adult authority isn't the only thing that matters. Around age three, fitting in with the group starts to count big too. |
| Causal mechanism of link between cancer and obesity Posted: 27 May 2021 08:24 AM PDT A review study advances knowledge about the connection between obesity-associated inflammation and cancer. The researchers suggest that inflammatory cells with immunosuppressive properties may act as a critical biological link between obesity and cancer risk, progression, and metastasis. |
| Escape from oblivion: How the brain reboots after deep anesthesia Posted: 27 May 2021 08:24 AM PDT An innovative study uses the anesthetics propofol and isoflurane in humans to study the patterns of reemerging consciousness and cognitive function after anesthesia. |
| When cancer cells 'put all their eggs in one basket' Posted: 27 May 2021 08:24 AM PDT Normal cells usually have multiple solutions for fixing problems that may arise. But cancer cells may 'put all their eggs in one basket,' getting rid of all backup plans and depending on just one solution. Researchers discovered that a particular type of blood cancer, acute myeloid leukemia, came to depend on a single DNA repair method. They developed a drug that shut down the remaining pathway in lab-grown cells. |
| Obsessive compulsive disorder linked to increased ischemic stroke risk later in life Posted: 27 May 2021 06:14 AM PDT Adults with obsessive-compulsive disorder (OCD) were more than three times as likely as those without the disorder to have an ischemic stroke later in life. Adults with OCD should maintain a healthy lifestyle, including not smoking, exercising, and managing a healthy weight, to help prevent stroke. Health care professionals should closely monitor patients with OCD for increased risk of ischemic stroke. |
| Posted: 26 May 2021 03:58 PM PDT In series of samples collected from individuals vaccinated against COVID-19, an ultrasensitive test detected low concentrations of circulating antigen. Following robust production of antibodies, investigators found that the viral protein declined to undetectable levels. |
| Inhaled nanobodies protect hamsters from COVID-19, study finds Posted: 26 May 2021 12:02 PM PDT Inhalable nanobodies targeting the spike protein of SARS-CoV-2 can prevent and treat severe COVID-19 in hamsters, according to new research. |
| How 'non-professional' cells can trigger immune response Posted: 26 May 2021 06:30 AM PDT Researchers are finding new details on the complex dynamics involved in how organisms sense an infection from pathogens. The researchers found that worms can sense changes in their metabolism in order to unleash protective defenses, even if they don't directly sense an incursion from pathogens. |
| SARS-CoV-2: Estimating infectiousness Posted: 25 May 2021 01:09 PM PDT Researchers have analyzed the PCR samples of more than 25,000 persons with COVID-19. The team determined the viral loads of each individual sample and used their results to estimate levels of infectiousness. The research provides a clear idea of the infectiousness of the disease in different age groups and at different levels of disease severity. |
| A COVID-fighter's guide to T cells Posted: 25 May 2021 01:08 PM PDT A new paper brings together research findings from COVID-19 researchers around the world. The results are striking: human T cells can target more than 1,400 sites on the SARS-CoV-2 virus. |
| Researchers uncover mechanism related to severe post-COVID-19 disease in children Posted: 25 May 2021 01:08 PM PDT Researchers have determined that viral particles remaining in the gut long after an initial COVID-19 infection can travel into the bloodstream, instigating the condition called Multisystem Inflammatory Syndrome in Children (MIS-C). |
