Weaponizing oxygen to kill infections and disease
The life-threatening bacteria MRSA can cripple a medical facility since it is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics, instead using light to activate oxygen, which wipes out bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.

A paper battery powered by bacteria
In remote areas of the world, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be too expensive. Today, researchers report a new type of battery -- made of paper and fueled by bacteria -- that could overcome these challenges.

New way to grow blood vessels developed
Formation of new blood vessels, a process also known as angiogenesis, is one of the major clinical challenges in wound healing and tissue implants. To address this issue, researchers have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels.

Novel nanoparticle-based approach detects and treats oral plaque without drugs
When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia. A team of researchers has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.

Microfossils, possibly world's oldest, had biological characteristics
Scientists have confirmed that the 3.4-billion-year-old Strelley Pool microfossils had chemical characteristics similar to modern bacteria. This all but confirms their biological origin and ranks them amongs the world's oldest microfossils.

Whole blood test for toxoplasmosis is sensitive, specific
Transmission of toxoplasmosis from mother to fetus can lead to severe congenital problems and fetal death, and tests for the parasitic infection during pregnancy are critical. Now, researchers have showed the efficacy of a low-cost whole blood test for toxoplasmosis.

Scientists create new technology and solve a key puzzle for cellular memory
With a new groundbreaking technique, researchers have managed to identify a protein that is responsible for cellular memory being transmitted when cells divide. The finding is crucial for understanding development from one cell to a whole body.
