Energy storage, DNA pyramid, killing antibiotic bacteria, killing cancer cells

Study of mechanics of photosynthesis promises efficient energy storage system

Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that powers life on our planet... Read more  

Tiny DNA pyramids kill bacteria more efficiently

Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics - and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids that can flag bacteria and kill more of them than medicine alone... Read more  

New method to kill antibiotic resistant bacteria

The infection causing bacteria have mechanisms that resist drugs, just like our bodies resist bacteria. This is the reason why doctors increase the dosage of medicine each for the same infection. A research team from Bangalore, India have developed a novel way to attack these bacteria, which gives the organisms little chance of developing resistance... Read more  

New formulation of chemotherapy drug to kill cancer cells effectively

University of Georgia researchers have developed a new formulation of cisplatin, a common chemotherapy drug that significantly increases the drug’s ability to target and destroy cancerous cells. It is an effective drug, but many cancerous cells develop resistance to the treatment... Read more

Chemical properties – Scandium symbol, electronic configuration, density

Scandium is a transition metal. It was discovered in 1879 by spectral analysis, of the minerals euxenite and gadolinite from Scandinavia. The main application of scandium by weight is in aluminium-scandium alloys for minor aerospace industry components. Some items of sports equipment, which rely on high performance materials, have been made with scandium-aluminium alloys. It is also used to make high-intensity discharge lamps.

Imaging flow of nanofluids

Nanofluids, fluids containing nanometer-sized particles, do not always behave as our experiences with the macro-world might lead us to expect. Water, for example, seems to flow much faster within carbon nanotubes than classical physics says should be possible. Now, researchers have found a way to directly image nanofluids... Read more

Researchers develop magnetically controlled liquid crystals

Chemists at the University of California, Riverside have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research paves the way for novel display applications relying on the instantaneous and contactless nature of magnetic manipulation... Read more

Michael Wong, Chemical Engineer, Rice University found evidences that palladium-gold nanoparticles are excellent catalysts for cleaning polluted water, but even he was surprised at how well the particles converted biodiesel waste into valuable chemicals... Read more

New ‘supercooling’ technique to preserve organs for longer

Scientists have developed a new supercooling technique to increase the amount of time human organs could remain viable outside the body. According to researchers, if it succeeds in humans, it would enable a worldwide allocation of donor organs, saving more lives and allow for more time to prepare the patient and ease logistics at the donor hospital site... Read more

New material helps faster healing of wounds

As many patients know, treating wounds has become far more sophisticated than sewing stitches and applying gauze, but dressings still have shortcomings. Now scientists are reporting the next step in the evolution of wound treatment with a material that leads to faster healing than existing commercial dressings and prevents potentially harmful bacteria from sticking... Read more
