Gene editing makes bacteria-killing viruses even more deadly
The viruses are engineered to damage essential E coli. genes. Enlarge (credit: Getty Images) Broad-spectrum antibiotics are akin to nuclear bombs, obliterating every prokaryote they meet. They're effective at eliminating.....»»
Spread of deadly EEE virus explodes 5-fold in New York; one death reported
Normally only 2 or 3 counties have EEE-positive mosquitoes; there's 15 this year. Enlarge / An entomologist for the Louisville Metro Department of Public Health and Wellness in a swampland area on August 25, 2021 in Louisville, K.....»»

Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Florida girds for arrival of Helene as powerful hurricane
Thousands of residents on Wednesday began evacuating parts of coastal Florida as the US state braces for Hurricane Helene, forecast to barrel ashore as a powerful, potentially deadly storm......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Deadly flooding in Central Europe made twice as likely by climate change
Human-caused climate change doubled the likelihood and intensified the heavy rains that led to devastating flooding in Central Europe earlier this month, a new flash study found......»»
Study finds good nutrition boosts honey bee resilience against pesticides, viruses
In a new study, researchers at the University of Illinois Urbana-Champaign tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors toget.....»»
Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Experts discover the deadly genetics of cholera, which could be key to its prevention
Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease......»»
Hungary Danube waters reach decade high after Storm Boris
The Danube peaked at a 10-year high in a heavily fortified Budapest on Saturday with the water reaching the steps of parliament, after deadly Storm Boris lashed Europe......»»

How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Study shows cholesterol enhances exosome-mediated RNA drug delivery
RNA interference (RNAi) technology has gradually become a cutting-edge technology for treating diseases such as genetic disorders and cancer due to its huge potential in gene expression regulation. However, the efficient delivery and safety of short.....»»
Team develops gene editing strategy for macroalgae Neopyropia
Neopyropia is an important economic macroalga and is one of the main macroalgae cultivation species in China, Japan, South Korea and other countries. As a critical juncture in the evolution of photosynthetic organisms, red algae to which Neopyropia b.....»»
