Ames Laboratory has developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields, by placing a tunnel diode resonator, an instrument that makes precise radio-frequency measurements of magnetic properties, in a dilution refrigerator, a cryogenic device that is able to cool samples down to milli-Kelvin temperature range.

Researchers found large amounts of viral DNA in key areas of the brains of Alzheimer’s patients CREDIT: REDHEAD ET AL

Decades of research show a striking correlation between Alzheimer’s disease risk and infection with Herpes Simplex Virus 1 (HSV1) in people carrying a specific gene. Now, newly-available epidemiological data provide a causal link between HSV1 infection and senile dementia – raising the tantalizing prospect of a simple, effective preventive treatment for one of humanity’s costliest disorders.

Professor Ruth Itzhaki. Her latest paper presents a lifetime of research evidence that the herpes virus responsible for cold sores can also cause Alzheimer’s – and new data which show antiviral drugs drastically reduce risk of senile dementia in patients with severe herpes infections...

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...
