Scientists have revealed for the first time the molecular steps that turn on bacteria's pathogenic genes. Using an array of high-powered X-ray imaging techniques, the researchers at the Department of Energy's Lawrence Berkeley National...Show More Summary
The supercoiling of bacterial chromosomes around histone-like proteins can trigger the expression of genes that make the microbe invasive, new research shows. The discovery could provide a new target for the development of drugs to prevent or treat bacterial infection, say scientists.
They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists at Kiel University, in cooperation with colleagues...Show More Summary
When the body encounters an infection, a molecular signaling system ramps up the body's infection-fighting system to produce more white blood cells to attack invading bacteria. Now researchers have discovered that when facing a massive bacterial infection resulting in sepsis, that same signaling system malfunctions, damaging the body's ability to fight the invaders.
Medical researchers have discovered novel virulence strategies employed by the Leishmania parasite. These scientific breakthroughs represent two important clues to understanding the cellular and molecular mechanisms governing the parasitic infections that cause leishmaniasis, a neglected tropical disease endemic in one hundred countries.
Bio-Rad Laboratories, Inc. (NYSE: BIO and BIOb), a global provider of life science research and clinical diagnostic products, today announced its entry into the rapidly growing molecular diagnostics testing market with the launch of Amplichek(tm) II quality control, which was recently issued a de novo clearance from the U.S. Food and Drug Administration (FDA).
The study of the mechanism of reactivation of acetylcholinesterase (AChE) inhibited by organophosphates (OP) is still a challenge for theoretical chemists since mechanistic studies, involve electronic transfer and breaking and formation of chemical bonds. Show More Summary
The molecular structure of a silica gel, shown in this illustration of a chemistry textbook or syllabus, has been described as "the chemical composition of a latina orgasm."
Scientists have been studying the factors influencing the development of different blood cells. Their research shows that certain molecular mechanisms are not as relevant as previously assumed. This finding helps to improve our understanding of diseases such as leukemia and anemia.
If you're already a spicy-food-lover, you're about to have all the more reason to douse your food in sriracha. A Nobel Prize winner, Rod MacKinnon, who studies molecular neurobiology, recently identified a possible cause for cramps and a solution while kayaking. Show More Summary

In 2014, an international trio won the Nobel Prize in Chemistry for developing super-resolution fluorescence microscopy, a technique that made it possible to study molecular processes in living cells. Now a Northwestern Engineering team has improved this groundbreaking technology by making it faster, simpler, less expensive, and increasing its resolution by four fold. read more
A new technology platform is able to image molecules at the nanoscale with super-resolution.
Researchers have revealed the molecular structure of a protein produced by the Zika virus that is thought to be involved in the virus's reproduction and its interaction with a host's immune system.
Scientists at Hokkaido University have revealed temperature-dependent energy-state conversion of molecular hydrogen on ice surfaces, suggesting the need for a reconsideration of molecular evolution theory. Molecular hydrogen, the most abundant element in space, is created when two hydrogen atoms bond on minute floating ice particles. Show More Summary
Scientists have revealed temperature-dependent energy conversion of molecular hydrogen on ice surfaces, suggesting the need for a reconsideration of molecular evolution theory.
Once again, countries outside the USA get the coolest Kit Kat treats — this time, literally. Tokyo pop-up shop "Kit Kat Chocolatory Wonderland” delves into the world of molecular gastronomy with the "Minus-196 Degrees Celsius Kit Kat,"...Show More Summary
In cooperation with colleagues of the University of Rostock, the University of Luxembourg, the Max Delbrueck Center for Molecular Medicine, the Karlsruhe Institute of Technology and the University of Eastern Finland, the Munich Scientists have now published the results in the journal PLOS ONE. read more
Scientists have developed software that allows observing cells for weeks while also measuring molecular properties. The software is freely available.
Environmental scientists can more efficiently detect genes required to convert mercury in the environment into more toxic methylmercury with new molecular probes.
