- Researchers construct most complex, complete synthetic microbiomeon September 6, 2022 at 4:48 pm
Key studies in the last decade have shown that the gut microbiome, the collection of hundreds of bacterial species that live in the human digestive system, influences neural development, response to cancer immunotherapies, and other aspects of health. But these communities are complex and without systematic ways to study the constituents, the exact cells and molecules linked with certain diseases remain a mystery.
- Keeping bacteria at bay in Hawaiian water bodieson September 6, 2022 at 4:44 pm
During heavy rains, Hawaii's streams, rivers, and nearshore waters change on microscopic levels. Bacteria in these aquatic systems increase, and some of these bacteria can be harmful to human health. They can cause problems like gastroenteritis—also known as the stomach flu—as well as skin and respiratory diseases.
- Change with age: As bats mature their immune cells differon September 6, 2022 at 4:20 pm
A team of researchers led by Anca Dorhoi at the Friedrich-Loeffler-Institut (FLI) and Emmanuel Saliba at the Helmholtz Institute for RNA-based Infection Research (HIRI), has elucidated age-dependent variations in cellular immunity in Rousettus aegyptiacus, known as the Egyptian fruit bat, a natural reservoir for filoviruses such as Marburg Virus.
- Roots rock: Chimpanzees drum to their own signature beatson September 6, 2022 at 4:11 pm
The drummers puff out their chests, let out a guttural yell, then step up to their kits and furiously pound out their signature beat so that everyone within earshot can tell who is playing.
- Researchers capture live footage of virus infecting cellon September 6, 2022 at 3:55 pm
In a first, scientists have captured on video all the steps a virus follows as it enters and infects a living cell in real time and in three dimensions.
- Harnessing the power of natural landscapes to eradicate pestson September 6, 2022 at 3:55 pm
Alpine ecosystems are under intense pressure from pest species, but University of Otago research has highlighted how the mountains themselves can be used to help eradicate them.
- How tardigrades survive dehydrationon September 6, 2022 at 3:55 pm
Some species of tardigrades, or water bears as the tiny aquatic creatures are also known, can survive in different environments often hostile or even fatal to most forms of life. For the first time, researchers describe a new mechanism that explains how some tardigrades can endure extreme dehydration without dying. They explored proteins that form a gel during cellular dehydration. This gel stiffens to support and protect the cells from mechanical stress that would otherwise kill them. These proteins have also been shown to work in insect cells and even show limited functionality in human cultured cells.
- Novel technique helps discover whether bacteria that cause meningitis are resistant to antibioticson September 6, 2022 at 3:51 pm
A study published in the journal PLOS ONE could one day help health workers determine whether bacteria of the species Streptococcus pneumoniae, which cause meningitis—an inflammation of the membranes that envelop the brain and spinal cord—are resistant to antibiotics.
- Characteristics of older forests can buffer effects of climate change for some bird specieson September 6, 2022 at 3:46 pm
Old-growth forests and managed forests with old-growth characteristics can provide relief from climate change for some bird species, research by the Oregon State University College of Forestry suggests.
- Discovery of new types of microfossils may answer an age-old scientific questionon September 6, 2022 at 3:43 pm
The Gunflint Formation, which straddles Lake Superior's northwestern shore, contains a treasure trove of geological clues about the evolution of life. After a recent geological reassessment of this area, a research team has unearthed new types of microfossils dating 1.9 billion years. The landmark discovery will help scientists pinpoint the timing and factors that ushered in the evolution of prokaryotes to eukaryotes.
- Researchers discover toxin that kills bacteria in unprecedented wayson September 6, 2022 at 3:00 pm
Researchers at McMaster University have discovered a previously unknown bacteria-killing toxin that could pave the way for a new generation of antibiotics.
- Bees use patterns, not just colors, to find flowerson September 6, 2022 at 2:48 pm
Honeybees rely heavily on flower patterns—not just colors—when searching for food, new research shows.
- Anger at plans to roll back Covid vaccines to under-11s in Englandby Nicola Davis Science correspondent on September 6, 2022 at 2:38 pm
Children aged 5-11 will no longer be offered Covid jabs, except those in clinical risk groups, UKHSA confirmsThe decision to reduce the number of children who are offered Covid jabs has prompted outcry from parent groups and academics.The UK Health Security Agency (UKHSA) said children who had not turned five by the end of last month would not be offered a vaccination, in line with advice published by the UK’s Joint Committee on Vaccination and Immunisation (JCVI) in February 2022. UKHSA said the offer of Covid jabs to healthy five to 11-year-olds was always meant to be temporary. Continue reading...
- The double life of Sp1: A protein's new role upends thinking about its impact on canceron September 6, 2022 at 2:37 pm
For four decades, Specificity Protein 1 (Sp1) has been cast solely as a transcription factor, a type of protein that binds DNA and turns genes on. But a Donnelly Center study has now revealed that Sp1 plays another unexpected role in gene regulation by influencing the stability of genes' RNA messages.
