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.....»»
Major energy companies conceal 47% of biodiversity damage, according to research
A study by the UPV/EHU's Research Group on Circular Economy, Business Performance and Achievement of Sustainable Development Goals reveals that energy companies conceal 47% of the damage wrought on biodiversity as a result of their activity. The stud.....»»
New compound found to be effective against "flesh-eating" bacteria
Researchers at Washington University School of Medicine in St. Louis have developed a novel compound that effectively clears bacterial infections in mice, including those that can result in rare but potentially fatal "flesh-eating" illnesses. The com.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Karaoke reveals why we blush
Volunteers watched their own performances as an MRI tracked brain activity. Enlarge (credit: Peter Muller) Singing off-key in front of others is one way to get embarrassed. Regardless of how you get there, why does embar.....»»
Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
Plant diseases pose significant challenges to agricultural productivity, presenting formidable hurdles that require urgent attention. Left unchecked, these diseases can spread rapidly, inflicting widespread damage on crops and leading to reduced yiel.....»»
Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»

Green synthesis of copper oxide nanoparticles from mangifera indica: A solution for agricultural disease management
A research team has successfully synthesized green copper oxide nanoparticles (CuO.NPs) from Mangifera indica (M. indica) leaf extract. The CuO.NPs showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on p.....»»
New derivative from long pepper shows promise against antibiotic resistance
Antibiotic resistant bacterial pathogens are on the rise, while fewer antibiotics are being developed. Prof. Ariel Kushmaro and his local and international colleagues tackled the need by focusing on the long pepper. Known in traditional medicine for.....»»
How bacteria attach their cloaks of invisibility to immune defenses
Bacteria have different strategies for protecting themselves. Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and.....»»
Imaging below the surface reveals one of Los Angeles"s webs of faults
A major fault is often surrounded by a web of secondary faults created as the forces that cause slip deform nearby rocks. This damage zone can act as a record of fault activity, but what we can learn from it—such as how the fault may behave during.....»»
