There's a particular set of chemical reactions that governs many of the processes around us--everything from bridges corroding in water to your breakfast breaking down in your gut. One crucial part of that reaction involves electrons striking water, and despite how commonplace this reaction is, scientists still have to use ballpark numbers for certain parts of the equation when they use computers to model them.

The current development of stretchable battery materials that mimic the functions of nature has emerged as a highly interesting research area, necessary for the next wave of wearable electronics.

AUSTIN, Texas -- Several measures of poor sleep quality were associated with higher body mass index (BMI) in children, according to data presented at the American Association for Cancer Research Special Conference Obesity and Cancer: Mechanisms Underlying Etiology and Outcomes, held Jan. 27-30.

About one in five children between the ages of 6 and 19 is obese, according to recent statistics from the Centers for Disease Control and Prevention. The percentage of U.S. children with obesity has more than tripled since the 1970s, with significant immediate and long-term effects.

AUSTIN, Texas -- Among men with prostate cancer who underwent radical prostatectomy (RP), those who were obese had a higher risk of biochemical recurrence, according to data presented at the American Association for Cancer Research Special Conference Obesity and Cancer: Mechanisms Underlying Etiology and Outcomes, held Jan. 27-30.

Biochemical recurrence was defined as two consecutive prostate-specific antigen (PSA) measurements of ≥ 0.2 ng/mL after prostatectomy, which is indicative of recurrent prostate cancer.

The plastic used in many second hand toys could pose a risk to children's health because it may not meet the most up to date international safety guidelines, according to new research published in Environmental Science and Technology.

Scientists from the University of Plymouth analysed 200 used plastic toys which they found in homes, nurseries and charity shops across the South West of England.

These included cars, trains, construction products, figures and puzzles, with all of them being of a size that could be chewed by young children.

Drawing from data collected for years by AIDS researchers in six African nations, scientists have pinpointed seven bacterial species whose presence in high concentrations may significantly increase the risk of HIV infection in women.

Until a decade ago, scientists were not aware that bacteria had complex immune systems - ones that could keep up with the pace of evolution in viruses called phages that infect bacteria. That changed with the discovery of what is now the most famous bacterial immune mechanism: CRISPR. Scientists realized that CRISPR is a natural gene editor, and it has revolutionized the world of biological research in thousands of labs around the world.

Spintronics in materials of just a few atoms thick is an emerging field in which the 'spin' of electrons is used to process data, rather than the charge. Unfortunately, the spin only lasts for a very short time, making it (as yet) difficult to exploit in electronics. Researchers from the Kavli Institute of Nanoscience at TU Delft, working with the Netherlands Organisation for Scientific Research's AMOLF institute, have now found a way to convert the spin information into a predictable light signal at room temperature.

The worldwide race to create more, better and reliable quantum processors is progressing fast, as a team of TU Delft scientists led by Professor Vandersypen has realised yet again. In a neck-and-neck race with their competitors, they showed that quantum information of an electron spin can be transported to a photon, in a silicon quantum chip. This is important in order to connect quantum bits across the chip and allowing to scale up to large numbers of qubits. Their work was published today in the journal Science.

The recent approval of SpinrazaTM (nusinersen), jointly developed by Ionis Pharmaceuticals and Biogen, marks the arrival of a new class of biological products - oligonucleotide therapeutics.
