6 science-backed ways to protect and improve your memory. via @sciencefocus realclearscience.com/2025/09/29/six…
"The more science investigates the origin of the universe, of life and of our species, the more improbable our existence seems. I have a hard time believing we’re here through sheer chance. But no version of God makes sense to me." by @Horganism realclearscience.com/2025/09/27/the…
"A new study... provides evidence that post-orgasmic illness syndrome, a little-known medical condition, may severely affect the emotional and relational well-being of those who experience it." via @PsyPost realclearscience.com/2025/09/27/the…
The Big Bang "is better thought of as a moment in time, not a location in space." by @StartsWithABang realclearscience.com/2025/09/27/whe…
Perplexing diamonds from South Africa mine contain 'almost impossible' chemistry. via @LiveScience realclearscience.com/2025/09/27/two…
Wow, that's a close-up of a bat.
"Red light therapy is promoted as a treatment for many conditions. The evidence for weight loss is not impressive. While some small studies suggest modest improvements in certain measures, the evidence is inconsistent..." via @ScienceBasedMed realclearscience.com/2025/09/26/red…
TikTok influencers make vagus nerve stimulate seem like a miracle cure. It's definitely not that, but... "From treating seizures to depression, stimulating the body's longest nerve has real benefits." via @PopSci realclearscience.com/2025/09/26/inf…
"Would you willingly have your legs broken, the bone stretched apart millimetre by millimetre and then spend months in recovery – all to be a few centimetres taller?" Many people are. via @ConversationUK realclearscience.com/articles/2025/…
At a wet-bulb temperature of 95 F, a human will die in about three hours. That's equivalent to when the air temperature is 102 F (38.9 C) and the relative humidity is 77%. via @LiveScience realclearscience.com/2025/09/26/the…
"The Dream Chaser spaceplane, which has been under development for two decades, now seems like it might be further than ever from taking flight." via @arstechnica realclearscience.com/2025/09/26/sie…
"A million-year-old human skull suggests that the origins of modern humans may reach back far deeper in time than previously thought and raises the possibility that Homo sapiens first emerged outside of Africa." via @guardianscience realclearscience.com/2025/09/26/sku…
"The idea that space-time exists is no more viable than the outdated belief that the celestial sphere exists: both are observer-centred models that are powerful and convenient for describing the world, but neither represents reality itself." realclearscience.com/articles/2025/…
"Earlier this century, some very strong evidence arrived showing that there was a Universe before the Big Bang, demonstrating that the Big Bang wasn’t truly the start of it all." by @StartsWithABang realclearscience.com/2025/09/25/the…
"A thorough health evaluation of one of the world's oldest people, Maria Branyas, suggests that one of the reasons she lived to 117 was that she possessed an exceptionally young genome." via @ScienceAlert realclearscience.com/2025/09/25/stu…
A newly found ancient Egyptian port may lead to Cleopatra’s tomb. via @arstechnica realclearscience.com/2025/09/25/dis…
Venus Is Hiding Massive Underground Tunnels That Are Much Bigger Than Expected. via @ZMEScience realclearscience.com/2025/09/25/ven…
"Infection rates from drug-resistant “nightmare bacteria” rose almost 70% between 2019 and 2023, according to a new report from Centers for Disease Control and Prevention scientists." via @AP realclearscience.com/2025/09/25/nig…
Astronomers might have discovered a mysterious object shining in the deep sky that could be older than the stars. Extraordinary essay by @andersen. This is the conclusion.
"When... facing the end of life, everything superficial just gets stripped away. The idea of taxes and politics and other things that we worry about are just gone, and you’re really focusing on love, relationship, healing, and, oftentimes, spirituality..." realclearscience.com/2025/09/24/wha…
