Eating vegetable nitrates, found mainly in green leafy vegetables and beetroot, could help reduce your risk of developing early-stage age-related macular degeneration (AMD).

A new study has shown that eating vegetable nitrates, found mainly in green leafy vegetables and beetroot, could help reduce your risk of developing early-stage age-related macular degeneration (AMD). Researchers at the Westmead Institute for Medical Research interviewed more than 2,000 Australian adults aged over 49 and followed them over a 15-year period.

The research showed that people who ate between 100 to 142 mgs of vegetable nitrates each day had a 35% lower risk of developing early AMD than people who ate less than 69mgs of vegetable nitrates each day...

Advances in supercapacitor technology could lead to wider use of fast-charging energy storage devices and novel designs for electronic gadgets. Scientists at UC Santa Cruz and Lawrence Livermore National Laboratory (LLNL) have reported unprecedented performance results for a supercapacitor electrode. The researchers fabricated electrodes using a printable graphene aerogel to build a porous 3D scaffold loaded with pseudocapacitive material.

In laboratory tests, the novel electrodes achieved the highest areal capacitance (electric charge stored per unit of electrode surface area) ever reported for a supercapacitor, said Yat Li, profes...

In this artist’s representation, an electron travels between two lasers in an experiment. The electron is spinning about its axis as a cloud of other subatomic particles are constantly emitted and reabsorbed. Some theories in particle physics predict particles, as yet undetected, that would cause the cloud to appear very slightly pear shaped when seen from a distance. With the support of the National Science Foundation, ACME researchers created an experiment setup look at that shape with extreme precision. To the limits of their experiment, they saw a perfectly round sphere, implying that certain types of new particles, if they exist at all, have properties different from those theorists expected.

NicA2-J1 reduces compulsive-like responding for nicotine in dependent rats.

Scientists at Scripps Research have successfully tested a potential new smoking-cessation treatment in rodents. In a study published online in Science Advances on Oct. 17, 2018, the scientists gave nicotine-dependent rats an engineered enzyme that breaks down nicotine in the bloodstream before it can reach the brain. Treatment quickly reduced the animals’ motivation to take nicotine, reversed their signs of nicotine dependence, and kept them from relapsing when they were given access to nicotine again.

“This is a very exciting approach because it can reduce nicotine dependence without inducing cravings and other severe withdrawal symptoms, and it works in the bloodstream, not the brain, so its side effects should b...
