| A rhythmic small intestinal microbiome prevents obesity and type 2 diabetes Posted: 05 Jul 2022 01:21 PM PDT Researchers found that in mice how much they ate and when altered the nature of their gut microbiome: too much food too frequently resulted in poorer microbial and metabolic health. |
| Daily avocados improve diet quality, help lower cholesterol levels, study finds Posted: 05 Jul 2022 01:21 PM PDT Eating one avocado a day for six months was found to have no effect on belly fat, liver fat or waist circumference in people with overweight or obesity, according to a new study. However, it did lead to a slight decrease in unhealthy cholesterol levels. |
| In Krabbe disease, neurons may bring about their own destruction Posted: 05 Jul 2022 01:21 PM PDT The gene defect underlying Krabbe disease causes degeneration of neurons directly, independent of its effects on other cell types, according to a new study. The discovery represents a new mechanism of action for the mutant gene, presenting a more accurate picture of the disease process that may help in the development of therapies. |
| Why it is so hard for humans to have a baby? Posted: 05 Jul 2022 01:21 PM PDT Medical researchers find an answer to the mystery of why most human embryos die young. |
| Scientists discover cancer trigger that could spur targeted drug therapies Posted: 05 Jul 2022 09:39 AM PDT Researchers definitively linked the function of a specific domain of proteins important in plant-microbe biology to a cancer trigger in humans, knowledge that had eluded scientists for decades. |
| Using big data to better understand cancerous mutations Posted: 05 Jul 2022 08:22 AM PDT The ideal method of determining what type of cancer mutation a patient has is to compare two samples from the same patient, one from the tumor and one from healthy tissue. Such tests can be complicated and costly, however, so researchers hit upon another idea -- using massive public DNA databases to look for common cell mutations that tend to be benign, so that researchers can identify rarer mutations that have the potential to be cancerous. |
| Posted: 05 Jul 2022 08:22 AM PDT A study has identified a molecule -- the purine inosine -- that boosts fat burning in brown adipocytes. The mechanism was discovered in mice, but probably exists in humans as well: If a transporter for inosine is less active, the mice remain significantly leaner despite a high-fat diet. |
| Nanoparticle vaccine protects against a spectrum of COVID-19-causing variants and related viruses Posted: 05 Jul 2022 07:38 AM PDT A new vaccine candidate, named mosaic-8, containing pieces of eight different SARS-like betacoronaviruses provides broad protection against other related coronaviruses. |
| Unchecked emissions could double heat-related child mortality Posted: 05 Jul 2022 07:38 AM PDT If carbon emissions are limited to slow temperature rise, up to an estimated 6,000 child deaths could be prevented in Africa each year, according to new research. New work estimated the impact of climate change on annual heat-related deaths of children under five years old in sub-Saharan Africa, from 1995 -- 2050. It shows that thousands of heat-related child deaths could be prevented if temperature increases are limited to the Paris Agreement's 1.5ºC target through to 2050. However, heat-related child deaths could double in sub-Saharan Africa by mid-century if high emissions continue. |
| Hereditary factors that increase the likelihood of cancer mutations detailed in new study Posted: 05 Jul 2022 07:38 AM PDT A new study reveals 42 hereditary genes which predispose individuals to a higher number of mutations that correlate with a greater probability of developing cancer. |
| Brain's response to understanding stories changes as we grow up Posted: 05 Jul 2022 07:38 AM PDT Scientists have shown how our brain's response to watching emotional and social stimuli in a movie changes between infancy and adulthood. |
| Study reveals why highly infectious cholera variant mysteriously died out Posted: 05 Jul 2022 07:38 AM PDT Scientists say continuous monitoring of the cholera bug genome is key to preventing outbreaks of new variants. |
| Fertility: Sperm screening might detect harmful mutations before embryo implantation Posted: 05 Jul 2022 07:38 AM PDT Screening sperm may help identify potentially harmful new genetic mutations and help fertility specialists prevent them from being passed on to offspring, shows a preliminary study. |
| Taking Vitamin D during pregnancy could lower the risk of eczema in babies Posted: 05 Jul 2022 06:38 AM PDT Taking Vitamin D supplements during pregnancy could substantially reduce the chances of babies up to a year old suffering from atopic eczema, according to a new study. |
| Link between recognizing our voice and feeling in control Posted: 05 Jul 2022 06:07 AM PDT Being able to recognize our own voice is a critical factor for our sense of control over our speech, according to a new study. If people think they hear someone else's voice when they speak, they do not strongly feel that they caused the sound. This could be a clue to understanding the experience of people who live with auditory hallucinations and could help to improve online communication and virtual reality experiences. |
| Coevolution of mammals and their lice Posted: 04 Jul 2022 03:09 PM PDT According to a new study, the first louse to take up residence on a mammalian host likely started out as a parasite of birds. That host-jumping event tens of millions of years ago began the long association between mammals and lice, setting the stage for their coevolution and offering more opportunities for the lice to spread to other mammals. |
| Genetic atlas for zebrafish 'breakthrough' for biomedical research Posted: 04 Jul 2022 03:09 PM PDT Medical and life science researchers will benefit from the most comprehensive atlas yet of genetic data on zebrafish, newly published research suggests. |
| Connectivity of language areas unique in the human brain Posted: 04 Jul 2022 03:09 PM PDT Neuroscientists have gained new insight into how our brain evolved into a language-ready brain. Compared to chimpanzee brains, the pattern of connections of language areas in our brain has expanded more than previously thought. |
| Researchers develop rapid COVID-19 test to identify variants in hours Posted: 04 Jul 2022 06:42 AM PDT In just a few hours, scientists can tell which variant has infected a COVID-19 patient -- a critical task that can potentially influence treatment decisions but takes days or weeks at most medical centers. |
| Researchers use AI to detect new family of genes in gut bacteria Posted: 04 Jul 2022 06:42 AM PDT Using artificial intelligence, researchers have discovered a new family of sensing genes in enteric bacteria that are linked by structure and probably function, but not genetic sequence. The findings offer a new way of identifying the role of genes in unrelated species and could lead to new ways to fight intestinal bacterial infections. |
| New antibody detection method for coronavirus that does not require a blood sample Posted: 01 Jul 2022 07:27 AM PDT Researchers have developed a rapid and effective antibody detection method for SARS-CoV-2 that is minimally invasive and applicable in resource-limited settings. Their methodology, which uses a patch sensor containing porous microneedles and a paper-based immunoassay, could have far-reaching implications for the blood-free detection of COVID-19 and many other infectious diseases. |
