While crop yield has achieved a substantial boost from nanotechnology in recent years, the alarms over the health risks posed by nanoparticles within fresh produce and grains have also increased. In particular, nanoparticles entering the soil through irrigation, fertilizers and other sources have raised concerns about whether plants absorb these minute particles enough to cause toxicity.

Scientists today track electrical signals and voltage changes in neurons and muscle cells by labeling individual cells or probing with electrodes. Scientists have now developed a new type of sensor that employs a sheet of graphene to get a continuous measure of electric field in these tissues. Electric fields change graphene's reflectance. The physicists found a way to amplify and measure the changes caused by action potentials in a beating embryonic chicken heart.

A new CF treatment strategy involves small, nucleic acid molecules called oligonucleotides that can correct some of the gene defects that underlie CF but are not addressed by existing modulator therapies. The researchers used a new delivery method that overcomes traditional obstacles of getting oligonucleotides into lung cells.

Philosophers, artists and scientists - and probably all the rest of us - have long obsessed over the key to human immortality. We all, no matter our income, culture or religion are bound to die. Even if we escape mortal diseases or accidents, we all face a deadly biological deterioration. While the debate of human longevity has divided the scientific community for centuries, a new study finds fresh evidence for our inevitable death.

Microplastic pollution of waterways has become a huge concern, with the tiny pieces of plastic entering food webs and potentially having harmful effects on animals and people. In addition, microplastics can act as breeding grounds for antibiotic-resistant bacteria. Now, researchers have analyzed antibiotic-resistance genes (ARGs) on five types of microplastics at different locations along the Beilun River in China, finding much higher abundances in urban than rural regions.
