How bacteria sleep through antibiotic attacks
Bacteria can survive antibiotic treatment even without antibiotic resistance by slowing down their metabolism and going into a type of deep sleep. A research team funded by the Swiss National Science Foundation reveals the changes bacteria undergo to.....»»
Attacks on health care during war are becoming more common, creating devastating ripple effects
The head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, has warned attacks on health-care workers, patients and facilities "must not become the norm.".....»»
Apple Watch sleep apnea detection gets approval from Health Canada
Following FDA approval in the United States earlier this month, Apple has now received the go-ahead from Health Canada for the Apple Watch’s sleep apnea notification feature. This means Apple is now permitted to roll out the feature to eligible App.....»»
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.....»»
Developing an effective cyberwarfare response plan
In this Help Net Security interview, Nadir Izrael, CTO at Armis, discusses how AI has transformed cyberwarfare by amplifying attacks’ scale and sophistication. Izrael emphasizes the need for AI-powered defenses and proactive cybersecurity strat.....»»
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.....»»
Companies mentioned on the dark web at higher risk for cyber attacks
The presence of any data relating to an organization on the dark web demonstrably increases its risk of a cyber attack, according to Searchlight Cyber. Dark web insights and breach correlation Marsh McLennan Cyber Risk Intelligence Center analyzed th.....»»
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.....»»
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.....»»
65% of websites are unprotected against simple bot attacks
Companies across industries are seeing more bot-driven attacks, both basic and advanced, according to DataDome. An analysis of over 14,000 websites uncovered alarming gaps in protection against cyber fraud, particularly within consumer-centric indust.....»»
Potential breakthrough in battle against antibiotic resistance from historic brine
A historic brine bath is the site of a potential breakthrough in the prevention of antibiotic resistance in relation to MRSA, and other hospital pathogens......»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
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.....»»
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.....»»
The Multiple Ways Climate Change Threatens to Make Migraines Worse
Migraine sufferers are often triggered by the weather, and research suggests warming temperatures and more extreme weather events worsen attacks......»»
