A striking study published in 2017 reported a 50% decline in the average sperm count since the 1970s. Now, a follow-up study is suggesting the decline in sperm counts is accelerating. But not all researchers are convinced the data is as clear as it seems.

Scientists in Israel have demonstrated a promising new technology for early Parkinson's diagnosis, using a variation of MRI to spot tiny, telltale structures forming deep in the brain as the disease progresses.

As sunlight passes through a building's windows it can cause indoor temperatures to rise, to the point that the structure's air conditioning system has to be used. A new window material, however, blocks incoming heat while staying mostly transparent.

Described by Foster + Partners as "inspired by science," the Edmond and Lily Safra Center for Brain Sciences in Jerusalem is defined by a laser-cut exterior that helps shade the interior while paying homage to a pioneer of modern neuroscience.

One of the challenges of farming lies in the fact that by the time plants appear to be stressed, it may already be too late to address the problem. A new potato, however, is designed to warn farmers by fluorescing at the earliest stages of stress.

Doctors fight cancer with everything from radiation to chemicals to light-reactive particles, with mixed outcomes. Now, a new study has combined two approaches – chemotherapy and light therapy – into one drug, with promising results.

Researchers have managed to reconstruct a Denisovan face for the first time, using DNA methylation mapping techniques.

​Amongst the challenges faced by the deaf is what's known as the "cocktail party effect," in which they have difficulty discerning one speaker's voice from others in crowded, noisy environments. A new device could help, however – by buzzing two of their fingers.

Is our entire universe just a computer simulation? Theoretical physicists believe they’ve found proof that our universe is far too complex to be captured in any simulation. According to the researchers, the hypothesis is done in by gravitational anomalies, tiny “twists” in the fabric of spacetime.

​A large-scale meta-analysis of 185 studies across 40 years has found a more than 50 percent decline in sperm concentration and total sperm count among men from North America, Europe, Australia and New Zealand. The rate of decline was found to be consistent and is cause for concern if it continues.

It turns out the fountain of youth might spurt smoke instead of a magical liquid. Researchers discovered that one of the active ingredients in marijuana – THC – was able to improve the brains of elderly mice to the level that they seemed like the brains of rodents who were only two months old.

According the Landmine Monitor 2016, global casualties from landmines reached a 10-year high in 2015 and funding for clearance efforts reached a 10-year low. A new system that highlights the location of landmines and unexploded ordnance using glowing bacteria could help reverse this trend.
