New smartphone clip-on can detect Zika virus in blood samples
29 Jul 2022 at 2:32pm
In a new study, researchers have combined their efforts to develop an instrument that can be clipped on to a smartphone to rapidly test for Zika virus in a single droplet of blood.
New DNA repair-kit successfully fixes hereditary disease in patient-derived c...
29 Jul 2022 at 2:32pm
Genetic mutations which cause a debilitating hereditary kidney disease affecting children and young adults have been fixed in patient-derived kidney cells using a potentially game-changing DNA repair-kit.
Plant-based 'meat' 'healthier and more sustainable than animal products'
29 Jul 2022 at 2:32pm
A new review focuses on the health and environmental benefits of plant-based products, as well as consumer attitudes.
It doesn't matter much which fiber you choose -- just get more fiber!
29 Jul 2022 at 2:32pm
The benefit of dietary fiber isn't just the easier pooping that advertisers tout. Fermentable fiber is an essential source of nutrients that your gut microbes and cells of the intestines need to stay healthy. Study participants who had been eating the least amount of fiber before being fed three different kinds of fiber supplement showed the greatest benefit from supplements, regardless of which ones they consumed.
Advanced imaging reveals mired migration of neurons in Rett syndrome lab models
29 Jul 2022 at 2:31pm
Using organoids to model early development, researchers used an emerging microscopy technology to see that new neurons struggled to reach their developmental destination.
New breath-driven concept set to transform access to hand prosthetics
29 Jul 2022 at 2:31pm
The new air-powered hand provides a lightweight, low-maintenance and easy-to-use body-powered prosthetic option particularly well suited for children and those in low and middle-income countries.
Interplay of ancestry and sexual dimorphism significantly affect growth patte...
29 Jul 2022 at 2:31pm
Researchers have found the development of the frontal sinus was affected more by sexual dimorphism than the ancestry of the individual and that it was the interplay between those two factors that produced the most significant variation.
Taking your time makes a difference
29 Jul 2022 at 2:31pm
Researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.
A fascinating new look at what drives T cells to guard the intestines
29 Jul 2022 at 2:31pm
Cells in the gut send secret messages to the immune system. Thanks to new research, we can finally get a look at what they're saying.
Where you live can affect your ability to conceive, study finds
29 Jul 2022 at 7:24am
People who live in socioeconomically deprived neighborhoods are about 20 percent less likely to conceive in any given menstrual cycle compared with people living in neighborhoods with more resources, a recent study found.
Disparities in United States COVID-19 vaccine distribution
28 Jul 2022 at 12:29pm
Health care facilities in Black metropolitan counties, Hispanic rural counties and hardest-hit counties were less likely to administer COVID-19 vaccines during initial rollout, a new study finds.
How molecular motor proteins are involved in malaria transmission
28 Jul 2022 at 11:30am
Scientists have made a major breakthrough in understanding how malaria parasites divide and transmit the disease, which could be a major step forwards in helping to prevent one of the biggest killer infections in the world.
Some types of stress could be good for brain functioning
28 Jul 2022 at 11:30am
It may feel like an anvil hanging over your head, but that looming deadline stressing you out at work may actually be beneficial for your brain, according to new research. The study found that low to moderate levels of stress can help individuals develop resilience and reduce the risk of developing mental health disorders, like depression and antisocial behaviors. Low to moderate stress can also help individuals to cope with future stressful encounters.
Decoding 'photoplethysmograms' to broaden the scope of health monitoring tech...
28 Jul 2022 at 11:30am
Advancing the potential applications of photoplethysmography, an optical technique used to measure heart rate, in cardiovascular and mental health monitoring requires the analysis of complex nonlinear data from photoplethysmograms (PPGs). Circumventing traditional analytical methods of resolving the complex and dynamic PPG signals, researchers have used nonlinear analysis to determine the accuracy of dynamical features estimated using short PPG signals.
Specialized brain regions recognize vocal cues that don't involve speech
28 Jul 2022 at 11:29am
New research finds that specific parts of the brain recognize complex cues in human vocal sounds that do not involve speech, such as crying, coughing or gasping. Insights into the organization of the brain voice-recognition system will enable researchers to better understand neurological disorders where voice perception is altered or missing and even help create better voice assistant devices.
