It Turns Out The "Grandmother Rule" Of Washing Your Body Is Correct
Scientists have investigated what they call the "Grandmother Hypothesis" when it comes to washing your skin, finding that people tend to miss several key areas, and their microbiome is less healthy as a result. So, if you want to stay healthy, listen to grandma. Read the full story here
The First-Ever Lunar Farm Shows That Plants Can Grow On The Moon
Plants are not just able to survive in low gravity such as on the Moon, two new papers suggest they may prefer it. It's been more than four years since China’s Chang'e-4 lander grew the first sprout on the Moon, but important experiment results have now been released and they suggest that for all the obstacles to establishing colonies on the Moon and Mars, growing food might not be one.

Smartphones Linked To "Spermageddon" In New Research: What To Know
New research has signaled that smartphones may impact the sperm quality of young men. Fear not, though. While researchers in the field have praised the robustness of the study, they have noted that the findings shouldn’t spark panic and the cause of humanity’s “spermageddon” remains elusive.

Hundreds Of Stars Have Vanished Without A Trace. Where Did They Go?
Earlier this week we reported the story of three stars that back in July 1952 disappeared within an hour from the night sky forever. In 2019, the Vanishing and Appearing Sources during a Century of Observations (VASCO) project attempted to catalog how many stars have disappeared from view in the last 70 years and found around 100 missing without a concrete explanation.

Where Would A Starfish Put Its Hat? Anywhere You Like – They're Mostly Head
When it comes to starfish, scientists have finally answered Basement Jaxx’s most famous question, Where's Your Head At? Turns out, all over their body, to the point where their body is essentially, well, a head. “It’s as if the sea star is completely missing a trunk, and is best described as just a head crawling along the seafloor,” said Laurent Formery, lead author of the study.

Four Technologies To Prevent The Looming Space Junk Apocalypse
According to the ESA, more than 10,500 satellites are currently circling Earth, and now, experts fear that maintaining order in space may become nigh impossible in just a few years. Fortunately, engineers are already developing technologies to prevent chaos from ruining the orbital environment. Read the full story here
