Chromium is used to make tool steel or stainless steel, and it’s thought to have been invented around the late 19th and early 20th centuries. Archaeologists have now discovered that Persians were mixing chromium into steel way back in the 11th century.

Researchers have conducted the world’s first meta-analysis of the relationship between PTSD and dementia. Encompassing over a million subjects the study found PTSD can double a person’s risk of developing dementia in their senior years.

The long-term results of a massive international trial, spanning almost two decades, has shown a single session of a novel form of radiotherapy is as effective in treating most breast cancers as a conventional radiotherapy plan lasting several weeks.

A new internet speed record has been clocked at an incredible 178 terabits per second (Tb/s) – fast enough to download the entire Netflix library in under a second. It's achieved by modulating light in new ways before beaming it down optical fibers.

A new study, led by researchers from University College London, is offering some of the first robust evidence showing how CBD, a key compound in cannabis, increases cerebral blood flow in memory processing regions of the brain such as the hippocampus.

A new study has demonstrated how a form of deep red light therapy can help address age-related decline in vision. Hitting the retina with just the right wavelength of light was found to recharge its energy system in those over 40 years old.

Two new studies are offering strong evidence that bowel inflammation and obesity are risk factors for developing dementia. The studies are observational, and cannot determine causality, but they build on prior research reaching similar conclusions.

When it comes to monitoring electrical activity in the brain, patients typically have to lie inside a large magnetoencephalography (MEG) machine. That could soon change, as scientists have developed a new version of a helmet that does the same job.

Two new studies, published in The Lancet Neurology, are suggesting increasing levels of a particular brain protein, detected in blood and spinal fluid, could be the earliest sign of neurodegenerative diseases such as Alzheimer’s and Huntington’s.

When it comes to accurately reading the brain's electrical signals, many systems utilize implantable electrodes. A new technology is reportedly less invasive yet just as accurate, as it swaps regular electrodes for ultra-thin wires.

Two new studies are demonstrating the development of diagnostic tests to detect prostate cancer. The research presents a urine test that can detect the disease in its early stages and a blood test that may catch the cancer as it begins to metastasize.

While we've already heard about light-activated germ-killing coatings, they generally require either ultraviolet or high-intensity light. A new one, however, works with regular low-intensity light, as might be found in offices or waiting rooms.
