Chlamydiae expand our view on how intracellular bacteria evolve
All chlamydiae today live inside the cells of hosts ranging from amoeba to animals. A team of scientists from the University of Vienna and the Wageningen University & Research found that the ancestor of chlamydiae likely already lived inside host cel.....»»
The most common authentication method is also the least secure
Despite the rise in cyber threats, many people do not have a holistic view of security, according to Yubico. The results of the survey uncovered concerning patterns and behaviors when it comes to personal and workplace cybersecurity, including the ex.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
NASA confirms space station cracking a “highest” risk and consequence problem
NASA and Roscosmos have not agreed on the point at which the leak rate is untenable. Enlarge / A high-resolution commercial Earth-imaging satellite owned by Maxar captured this view of the International Space Station on June 7 wi.....»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»
Daily 5 report for Sept. 26: This Jeep story reinforces why auto shows are suffering
What better way to make a new-vehicle splash than to do the unveiling on the 46th floor of a Tokyo high-rise with a breathtaking view of the nation's capital?.....»»
Why the gender gap in physics has been stable for more than a century
As a physicist and data scientist with a keen interest in gender inequality, Fariba Karimi was amazed to discover that the gender gap in physics has remained almost unchanged since 1900. As the citation and coauthorship networks in physics expand, wo.....»»
Overheard: View your repair shop from the perspective of the customer
Shop owners should spend a couple hours each month thinking about how the customer perceives their repair facility, Lauralee Schmidt, co-owner of Schmidt Auto Care in Springboro, Ohio, said on the "Ratchet+Wrench Radio" podcast......»»
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.....»»
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.....»»
Shrinking augmented reality displays into eyeglasses to expand their use
Augmented reality (AR) takes digital images and superimposes them onto real-world views. But AR is more than a new way to play video games; it could transform surgery and self-driving cars. To make the technology easier to integrate into common perso.....»»
Blocking someone on X is about to get pointless
So it seems that X is making changes to how blocking someone works, where the blocked user can still view public posts. The post Blocking someone on X is about to get pointless appeared first on Phandroid. Blocking someone in messenger or.....»»
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.....»»
From pollution to power: Merging wastewater treatment and energy generation with capacitive MFC innovations
Imagine standing on the edge of a new frontier, where waste—something we often view as a problem—becomes the solution. We live in a world that needs innovation, where environmental challenges demand a sustainable approach, and where we need techn.....»»
Offensive cyber operations are more than just attacks
In this Help Net Security interview, Christopher Jones, Chief Technology Officer and Chief Data Officer at Nightwing, talks about some key misconceptions and complexities surrounding offensive cyber operations. Many myths stem from a simplistic view.....»»
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......»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
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.....»»
Plants could still grow well under alien skies
Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto land, protected from the.....»»
