In 1347, the Bubonic or Black Plague first entered the Mediterranean via trade ships transporting goods from the territories of the Golden Horde in the Black Sea.

The disease tore through Europe, the Middle East and northern Africa, in some cases claiming up to 60 percent of the population. It resurged throughout the next 500 years.
Scientists just published a study of what may prove to be China's most ancient human fossil. The researchers employed microCT, geometric morphometry, and classical morphology techniques to investigate the remains of the maxillary and five teeth from the skull unearthed at the Chinese site of Gongwangling, on the vast plains on the northern slopes of the Quinling Mountains (province of Shaanxi, in central China) and was discovered by the scientist Woo Ju-Kang in 1963.
Though activists try to portray farmers as slathering pesticides and fertilizer on land, anyone who has farmed know it is just the opposite; land is their greatest asset and given price competition they need to control costs and inputs as much as possible.
It's difficult to imagine that a simple dietary intervention could mean less Alzheimer’s disease but that is why observational studies and epidemiology claims are placed into the exploratory pile until science can take a look.

A new paper correlates people with a higher  red blood cell (RBC) docosahexaenoic acid (DHA levels as 49% less likely to develop Alzheimer’s disease vs. those with lower levels, especially for those carrying the ApoE4 gene, which is also a risk factor for Alzheimer's. You know that correlation is not causation so modifying two risk factors with unclear biological meaning may or not be better than doing nothing and hoping for the best. 
A new study correlates SARS-CoV-2 specific T cells to lung function and those who suffer from long-term COVID symptoms, which impacts an unclear number of people.

The study found that patients suffering from long COVID symptoms had virus-specific T cell levels more than 100 times higher than those who recovered from the disease.
About 94 percent of the universe is not detectable matter and the universe is expanding. Those two facts alone are how scientists recognize that gravity as we know it does not work at the very large scale.

It also does not work at the very small. Various bits of speculation, hypothesis, and science-fiction have tried to account for macro effects and they get lumped under generic blanket terms like 'dark matter' and 'dark energy' but experimental physics leads the charge in turning science from fantasy into reality. A new paper has made a step closer to understanding the quantum excitation known as the axial Higgs mode, which unlike the Higgs Boson has a magnetic moment. There is no end to theoretical claims about an axial Higgs mode but reality has been more elusive.
