It is possible to make a brand new baby universe in the laboratory? How would we do it? And if we made one, what would we do with it?

A nice introduction to the topic is this paper: https://arxiv.org/abs/1512.01819 which also contains the 10kg bound that I mention.

Does hot weather lead to increased violence? These researchers found a connection

Ever noticed a spike in your temper when you’re uncomfortably warm? Found yourself in a fit of rage when you’re all sweaty and it’s unbelievably hot outside?

If you did, have you blamed it on the weather?

Sure, you may have attributed a mood swing or two to an overcast sky, but is there a pattern you’ve observed over time? Maybe not. But if you did, you’re not alone.

Scientists scanned the laser, accidentally discovered a ghost temple appearing at the bottom of the bay

According to Heritage Daily, the legendary temple was discovered when a joint research team between the University of Seville and the Institute of Andalusian Historical Heritage (IAPH) used LiDAR, a laser remote sensing technique, to scan the Bay of Cádiz.

LiDAR images reveal hidden structures – (Image: IAPH).

They recognized a large rectangular structure submerged under water that Dr Francisco José Gacía, director of the University of Seville’s Department of Prehistory and Archeology, described to El Pais as a “spectacular find”.

Scientists use stem cells to create synthetic mouse embryos

Scientists have created “synthetic” mouse embryos from stem cells without a dad’s sperm or a mom’s egg or womb.

The lab-created embryos mirror a natural mouse embryo up to 8 ½ days after fertilization, containing the same structures, including one like a beating heart.

In the near term, researchers hope to use these so-called embryoids to better understand early stages of development and study mechanisms behind disease without the need for as many lab animals. The feat could also lay the foundation for creating synthetic human embryos for research in the future.

Space Biology, Psychology Studies Help NASA Plan Future Missions

Life science continued dominating the research schedule aboard the International Space Station on Wednesday to benefit humans living on and off the Earth. The seven Expedition 67 orbital residents explored how living in microgravity affects tissue regeneration, crew psychology, and the human digestion system.

Learning to heal wounds in space is critical as NASA and its international partners plan crewed missions to the Moon, Mars, and beyond. Four station astronauts have been partnering together this week for the skin healing study taking place inside the Kibo laboratory module. Flight Engineers Kjell Lindgren, Bob Hines, and Jessica Watkins, all from NASA, with Samantha Cristoforetti of ESA (European Space Agency), are studying surgical techniques such as biopsies, suture splints, and wound dressing, inside Kibo’s Life Science Glovebox.

Scientists on Earth seek to identify the molecular mechanisms that occur during tissue regeneration in weightlessness. Observations may offer advanced therapies and provide insights into how space-caused accelerated skin aging affects an astronaut’s healing properties. The biomedical experiment may also contribute to better wound healing techniques on Earth.

Facebook Bug Causes Users’ Feeds to Be Spammed

Facebook suffered a bug leading to users’ feeds being spammed with posts from strangers on the pages of celebrities on the site earlier today.

The social media platform’s parent company Meta blamed the problem on a “configuration change” in a statement to Metro.co.uk, adding: “We resolved the issue as quickly as possible for everyone who was impacted, and we apologize for any inconvenience.”

The technical glitch meant that when anyone posted a comment on a celebrity’s page, it appeared on the feed of anyone who followed that celebrity. This issue reportedly began at around 6.30 am BST on Wednesday, August 24.
