The Sun Has Reached Solar Maximum, Microplastics Detected in Wild Dolphin Breath, And Much More This Week

This week, the most complete thylacine genome yet has been reconstructed in a push for de-extinction, high-THC cannabis leaves a unique signature on users’ DNA, and gravity may be to blame for Neanderthals never adopting advanced spear-throwing technology. Finally, here’s what to know about the common eye condition, astigmatism.

Expect Geomagnetic Storms And Aurora: The Sun Has Reached Solar Maximum, NASA Announces

Solar activity increases and decreases over the 11-year solar cycle – also known as the Schwabe cycle – now, NASA has announced that the Sun has reached its solar maximum period in the solar cycle, with more geomagnetic storms and aurora expected in the coming months. Read the full story here

Most Complete Thylacine Genome Yet Reconstructed In Push For De-Extinction, Company Claims

Scientists claim to have pieced together the most complete genome of a Tasmanian tiger to date – with the help of RNA from a head that’s been preserved in alcohol for over a century. The potential breakthrough is the latest chapter in an effort by Colossal Biosciences and the University of Melbourne’s Thylacine Integrated Genetic Restoration Research (TIGRR) Lab to resurrect the extinct animal, also known as a thylacine.

Microplastics Detected in Wild Dolphin Breath For The First Time

Microplastics seem to be everywhere in 2024, with new studies revealing the tiny contaminants in human brains, penises, and even human placentas. Now, new research has looked at the impact of microplastics on free-ranging dolphins in the USA and has found that even these intelligent cetaceans are not able to escape, with their breath found to contain microscopic plastic fragments.

High-THC Cannabis Leaves A Unique Signature On Users’ DNA

High-potency cannabis alters users’ DNA in ways that weaker strains don’t, new research has revealed. In particular, ultra-strong weed appears to interfere with genes related to immunity and cellular energy production, and leaves a distinct mark on the DNA of cannabis users who go on to develop psychosis.

Neanderthals Never Adopted Advanced Spear Throwing Technology. Might Gravity Be To Blame?

Spears work better when thrown from a height, but a surprising study finds the same does not apply to weapons launched from an atlatl (spear thrower). This could explain the apparent non-adoption of throwing devices by Neanderthals. Although there is nowhere near enough evidence to adopt such a conclusion with confidence, it’s possible that such a failure may have placed Neanderthals at a disadvantage in competing with Homo sapiens.

Astigmatism: Here’s What To Know About This Common Eye Condition

You might’ve guessed already from the title (or hearing the term bandied about in an optometrist’s office), but astigmatism is an eye problem that leads those with it to have symptoms including blurry vision – you’ve probably heard of it, you might even have it, but what does it actually mean? Let’s find out. Read the full story here
