  In a major anti-terror operation , Haryana Police have seized over 2,900 kilograms of explosive making material from two houses in Faridabad, unearthing what appears to be a large terror module spread across several states. Along with the explosive material, an assault rifle, over a dozen explosive timers, and a significant quantity of ammunition were recovered. The discovery has raised serious security concerns, as ammonium nitrate is known for its potential to cause devastating explosions under specific conditions. What is Ammonium Nitrate? Ammonium nitrate is a white, crystalline compound commonly used as a fertiliser. Chemically, it is a salt made from ammonium and nitrate ions, formed by combining ammonia with nitric acid. Its high nitrogen content makes it valuable in agriculture, while its oxidising properties enable it to support combustion when mixed with other substances. Although stable under normal conditions, it becomes highly dangerous if mishandled or combined with...

  A new study has revealed that specialised immune cells in the brain, known as microglia, may help slow the progression of Alzheimer’s disease by reducing inflammation and blocking harmful protein buildup. The discovery offers promising insight into potential immunotherapy treatments for neurodegenerative disorders. Microglia as Brain Protectors Researchers have identified a subset of microglia that play a protective role against Alzheimer’s pathology. These cells, when exhibiting lower levels of a protein called PU.1 and higher levels of the receptor CD28, were found to reduce inflammation and restrict the accumulation of amyloid plaques and toxic tau proteins — both key markers of Alzheimer’s. Role of PU.1 and CD28 in the Brain PU.1 is a transcription factor that determines which genes are activated in immune cells, while CD28 is a receptor that helps immune cells communicate and function effectively. The study showed that reducing PU.1 levels in microglia encouraged them to be...

  New research has revealed that Escherichia coli (E. coli) , a bacterium that normally lives in the human gut, can spread through populations at a rate comparable to the swine flu. For the first time, researchers from the Wellcome Sanger Institute, the University of Oslo, the University of Helsinki, Aalto University in Finland, and their collaborators have been able to estimate how efficiently one person can pass gut bacteria to others. This kind of calculation, which measures transmission rates, has previously been possible mainly for viruses. Tracking Dangerous Strains Across Populations The study, published today (November 4) in Nature Communications, examined three key E. coli strains circulating in the UK and Norway. Two of these strains are resistant to several common classes of antibiotics. They are also the most frequent causes of urinary tract and bloodstream infections in both countries. The researchers suggest that better monitoring of these strains could guide public h...

  Staphylococcus aureus, a bacterial species responsible for staph infections, latches onto human skin with one of the strongest biological bonds ever recorded, researchers report in the Sept. 5 Science Advances. This powerful grasp is strengthened by the mineral calcium, preventing bacterial cells from being washed or brushed away from skin. An influx of calcium to damaged skin, such as a cut or a condition like eczema, is “a way of growing your skin faster,” says Rafael Bernardi, a biophysicist at Auburn University in Alabama. But “the mechanism that we use to fix a bruise is the same mechanism that the bacteria take advantage of to bind better to our skin.” A common skin microbe, S. aureus can invade the body through cuts and scrapes to cause skin infections such as cellulitis or life-threatening systemic infections when staph spreads to other parts of the body. Disrupting the super strong bond between staph and skin could help researchers develop new treatments. Bernardi and c...

For decades, engineers and scientists have been searching for the ideal material to withstand the relentless assault of the ocean — the corrosive salt, the immense pressure, and the biological fouling that destroy most metals over time. Among all the materials tested, titanium alloys have emerged as the true champions of the sea, often referred to as seawater’s secret weapon. Their exceptional combination of strength, corrosion resistance, and longevity makes them indispensable in marine engineering, naval defense, and offshore energy applications. The Challenge of Seawater Corrosion Seawater is one of the most aggressive natural environments for metals. It contains chlorides, dissolved oxygen, and microorganisms that attack most structural materials, leading to rapid corrosion and degradation. Traditional metals like steel and aluminum require coatings, cathodic protection, or regular maintenance to survive prolonged exposure. Even stainless steels, known for their corrosion resistan...

  Astronomers have detected the brightest black hole flare ever recorded, an event that shone with the energy of 10 trillion suns after a supermassive black hole began devouring a large star, reported. "This is really a one-in-a-million object," said lead author Matthew Graham, a research professor of astronomy at the California Institute of Technology. The observed black hole flare is believed to be the largest and most distant one ever recorded, coming from 10 billion light-years away. This phenomenon occurred when a massive star, estimated to be at least 30 times the mass of our sun, wandered too close to a supermassive black hole and was torn apart, releasing an enormous amount of energy. According to Graham, the massive outburst's intensity and duration point to a black hole flare as the most plausible explanation. Further studies will help confirm the findings. While black holes regularly consume nearby matter, an event of this magnitude is extremely rare, Graham n...

  “If we’re going to build a circular, sustainable economy, the chemical industry is a big, complex problem that we must address,” said Professor Erwin Reisner from Cambridge’s Yusuf Hamied Department of Chemistry, who led the research. “We’ve got to come up with ways to de-fossilize this important sector, which produces so many important products we all need. It’s a huge opportunity if we can get it right.” Now, a team led by the University of Cambridge is exploring innovative approaches that could eventually “de-fossilize” this vital industry. Their breakthrough involves a hybrid device that brings together light-absorbing organic polymers and bacterial enzymes to transform sunlight, water, and carbon dioxide into formate, a clean fuel that can power additional chemical reactions. This “ semi-artificial leaf” replicates photosynthesis, the natural process plants use to turn sunlight into energy, and operates entirely on its own power. Unlike previous designs that relied on toxic...
