Worms use electricity to jump      (via sciencedaily.com)     Original source 

In nature, smaller animals often attach themselves to larger ones to 'hitch a ride' and save energy migrating large distances. Researchers show how microscopic Caenorhabditis elegans worms can use electric fields to 'jump' across Petri plates or onto insects, allowing them to glide through the air and attach themselves, for example, onto naturally charged bumblebee chauffeurs.

Scientists discover critical factors that determine the survival of airborne viruses      (via sciencedaily.com)     Original source 

Critical insights into why airborne viruses lose their infectivity have been uncovered. The findings reveal how cleaner air kills the virus significantly quicker and why opening a window may be more important than originally thought. The research could shape future mitigation strategies for new viruses.

A new tool to study complex genome interactions      (via sciencedaily.com)     Original source 

Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.

New insights on bacteria that causes food poisoning      (via sciencedaily.com)     Original source 

A joint research group has clarified how pathogenic genes in some Providencia spp., which have gained attention as causative agents of food poisoning as well as enterohemorrhagic Escherichia coli. O157 and Salmonella, are transferred within bacterial cells. Their findings are expected to provide new insights into the identification of infection routes of Providencia spp. and the establishment of preventive methods for food poisoning.

How fungus farming ants keep their gardens healthy      (via sciencedaily.com)     Original source 

'Weed early and often' is the key to a productive garden. Interestingly, certain species of ants are also avid gardeners, a practice they've refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report how ants distinguish the good fungus from the bad.

Tethering of shattered chromosomal fragments paves way for new cancer therapies      (via sciencedaily.com)     Original source 

Scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous mutations.

Genome editing used to create disease resistant rice      (via sciencedaily.com)     Original source 

Researchers have used the genome-editing tool CRISPR-Cas to create disease resistant rice plants, according to a new study. Small-scale field trials in China show that the newly created rice variety exhibited both high yields and resistance to the fungus that causes a serious disease called rice blast.

Close up on aging reveals how different cell types in the body age at different pace      (via sciencedaily.com)     Original source 

A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.

Fewer meals may prevent Type 2 diabetes, obesity      (via sciencedaily.com)     Original source 

When intermittent fasting became all the rage among Hollywood celebrities, skeptics balked at the idea of skipping meals. But new research suggests the celebs might not have been that far off. The review found that a specific type of restricted eating may reduce the chances of developing Type 2 diabetes and improve your overall health. Known as time-restricted eating, this type of fasting means having regular but fewer meals, cutting out late-night snacks and not eating for 12 to 14 hours (often overnight).

Technique restores healthy bacterial balance in C-section babies      (via sciencedaily.com)     Original source 

Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study. In the first randomized study of its kind, a team of researchers found the process, known as vaginal seeding, definitively engrafted new strains of maternal bacteria in the babies' bodies.

The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark      (via sciencedaily.com)     Original source 

A survey of groundwater samples drawn from aquifers beneath more than 80,000 square miles of Canadian prairie reveals ancient groundwaters harbor not only diverse and active microbial communities, but also unexpectedly large numbers of microbial cells. Strikingly, some of these microbes seem to produce 'dark oxygen' (in the absence of sunlight) in such abundance that the oxygen may nourish not only those microbes, but may leak into the environment and support other oxygen-reliant microbes that can't produce it themselves.

Altered gut bacteria may be early sign of Alzheimer's disease      (via sciencedaily.com)     Original source 

Alzheimer's disease causes changes to the brain that begin two decades or more before symptoms appear. A study reveals that the bacteria that live in the gut also change before Alzheimer's symptoms arise, a discovery that could lead to diagnostics or treatments for Alzheimer's disease that target the gut microbiome.
