Without Egg, Sperm or Womb: Synthetic Mouse Embryo Models Created Solely from Stem Cells – Life Sciences | Weizmann Wonder Wander
An egg meets a sperm – that’s a necessary first step in life’s beginnings, and it’s also a common first step in embryonic development research. But in a Weizmann Institute of Science study published today in Cell, researchers have grown synthetic embryo models of mice outside the womb by starting solely with stem cells cultured…

This ultrasound patch could let you watch your own heart beat
Picture a smartwatch that doesn’t just show your heart rate, but a real-time image of your heart as it beats in your chest. Researchers may have taken the first step down that road by creating a wearable ultrasound patch — think of a Band-Aid with sonar — that provides a flexible way to see deep inside…

Women don’t like to participate in competitive situations when deciding for themselves, but when deciding for others, they are all in, new research finds — ScienceDaily
Although most decisions in life are made by individuals themselves, many are influenced by others such as principals, managers, parents or colleagues. New research in the INFORMS journal Management Science finds that women take part in competitive environments more when they are making decisions for other people rather than themselves. “We find that women shy…

Famine and disease may have driven ancient Europeans’ lactose tolerance
Ancient Europeans may have evolved an ability to digest milk thanks to periodic famines and disease outbreaks. Europeans avidly tapped into milk drinking starting around 9,000 years ago, when dairying groups first reached the continent’s southeastern corner, researchers report July 27 in Nature. Yet it took several thousand years before large numbers of Europeans evolved…

A balancing act between success and disappointment — ScienceDaily
Higher aspirations lead to higher achievements. At least, that is true in the context of educational and occupational aspirations, as shown by a new study co-authored by economist Dr. Reto Odermatt of the University of Basel. Unrealistically high aspirations as a teenager, however, can have a negative effect on well-being as an adult. Over the…

How to make jet fuel from sunlight, air and water vapor
Jet fuel can now be siphoned from the air. Or at least that’s the case in Móstoles, Spain, where researchers demonstrated that an outdoor system could produce kerosene, used as jet fuel, with three simple ingredients: sunlight, carbon dioxide and water vapor. Solar kerosene could replace petroleum-derived jet fuel in aviation and help stabilize greenhouse…

Here’s the quickest way to grill burgers, according to math
If you have a hankering for a hamburger, math may have some timesaving cooking tips for you. Increasing the number of times a burger is flipped from one side to the other reduces its cook time by up to nearly a third, theoretical calculations suggest. But cooks at home probably won’t see much benefit out of…

Ancient DNA links an East Asian Homo sapiens woman to early Americans
A previously undetected Homo sapiens population inhabited what’s now southwestern China around 14,000 years ago and contributed to the ancestry of ancient Americans. This far-ranging Asian group’s evolutionary identity has been revealed thanks to ancient DNA extracted from a skullcap previously excavated at Mengzi Ren, or MZR, a site in southwestern China’s Red Deer Cave,…
