Here’s how to get your free 40% performance boost from AMD
If you own an AMD RX 6000-series graphics cards, your GPU just got an unexpected performance boost. Here's how to unlock it......»»
Examining how bacteria manipulates the immune response to spread unnoticed
Bacterial toxins have always been seen as dangerous molecules—but may also act as negotiators between bacteria and the host immune response to enable long-term infection. Anna Bergonzini, at the Department of Molecular Biology at Umeå University,.....»»
The secrets of polydopamine coatings revealed
Dopamine is best known as a neurotransmitter. What is rather unknown, however, is that the underwater glue used by mussels contains large amounts of L-Dopa molecules, an analog of dopamine......»»
Stevia based sweeteners may offer a sweeter, more environmentally friendly alternative to sugar
Natural sweeteners derived from stevia may produce as little as 10% of the greenhouse gas emissions of sugar while still providing the same level of sweetness, according to new research from the University of Surrey......»»
Reduced energetic disorder enables over 14% efficiency in organic solar cells
Non-fused-ring organic photoactive materials have attracted broad attention in recent years due to their low synthetic cost. Different from the rigid coplanar structure of fused-ring molecules, the easily rotated conformation of non-fused-ring molecu.....»»
Scientists present a new method for imaging individual electrons
Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter—which is great for determining whether, for example, a meniscus in the knee is torn. B.....»»
Mapping molecular funnels with X-rays: Precise timings of non-adiabatic excited state dynamics
Time-resolved spectroscopy is a tool that provides access to the time-scale of chemical reactions as they happen. With the help of ultra-short light pulses, it is possible to observe conformal changes in molecules on the time-scale of the atomic moti.....»»
Bread made from a new type of flour keeps you fuller for longer
Bread made from a new type of whole cell pulse flour can lower blood glucose (sugar) levels and keep you fuller for longer, new research has found......»»
Scientists develop AI-based method to predict RNA modifications
A team of researchers from the Agency for Science, Technology and Research (A*STAR) and the National University of Singapore (NUS) has developed a software method that accurately predicts chemical modifications of RNA molecules from genomic data. The.....»»
Artificial sweetener as a wastewater tracer
Acesulfame is a sweetener in sugar-free drinks and foods. As it cannot be metabolized in the human body, the sweetener ends up in wastewater after consumption and remains largely intact even in sewage treatment plants. A new study by the University o.....»»
A possible strategy for a tabletop chiral attosecond laser
When molecules form from many atoms, the atoms can combine in different ways. Two forms of the same molecule can have the same composition but have different arrangements of atoms, giving rise to isomers. Some isomers may have structures that are mir.....»»
Rabi oscillations in a stretching molecule
Over eighty years ago, Rabi oscillations were proposed to describe the strong coupling and population transfer in a two-level quantum system exposed to an oscillatory driving field. As compared to atoms, molecules have an extra degree of vibration, w.....»»
What animal kills the most humans? Here"s the unexpected predator and how to protect yourself
Between frightening movies like "Jaws" and tales about deadly animal encounters, some fear the wild animal kingdom because of potential danger......»»
Lear net income rallies to $118M in Q4 despite continued production issues
Lear landed an unexpected conquest late last year to supply an undisclosed automaker's SUV platform in North America with just-in-time thermal comfort seating......»»
Recreating the natural light-harvesting nanorings in photosynthetic bacteria
Nearly all the chemical energy available to Earth's lifeforms can be traced back to the sun. This is because light-harvesting (LH) supramolecules (two or more molecules held together by intermolecular forces) enable plants and some types of bacteria.....»»
Genetic engineering sheds light on ancient evolutionary questions
Cyanobacteria are single-celled organisms that derive energy from light, using photosynthesis to convert atmospheric carbon dioxide (CO2) and liquid water (H2O) into breathable oxygen and the carbon-based molecules like proteins that make up their ce.....»»
Examining the chemicals involved in insect mating
It's almost Valentine's Day, and love is in the air. Or in the waxy coating on your skin, if you are a vinegar fly. That's where flies encounter pheromones that play an important role in regulating sexual attraction......»»
New study into tuberculosis membrane molecules could aid drug delivery
A new method to aid in the development of antibiotics for tuberculosis (TB) infections has been devised......»»
Study finds unexpected interactions in formation of secondary organic aerosols in the atmosphere
Secondary organic aerosol (SOA) consists of extremely small particles generated in the atmosphere from natural and human-made emissions. It is a major constituent of PM2.5 (particulate matter with a diameter smaller than 2.5 micrometers) worldwide th.....»»
