Study: Poverty, not trauma, affects cognitive function in refugee youth

Study: Poverty, not trauma, affects cognitive function in refugee youth

Poverty, not war-related trauma, drives cognitive deficits in young people displaced by conflict, according to a new Yale-led study of adolescents affected by the crisis in Syria.  The study, published in the journal Child Development, is the first to test executive function — a set of higher-order cognitive skills required for abstract thinking, decision making,…

Meta-analysis study indicates we only publish positive results

So meta — Meta-analyses will only produce more reliable results if the studies are good. John Timmer - Dec 29, 2019 2:15 pm UTC Andrew Brooks | Getty ImagesWhile science as a whole has produced remarkably reliable answers to a lot of questions, it does so despite the fact that any individual study may not…

Study: Future astronauts could use their own urine to help build moon bases

U is for urea — Urea could serve as plasticizer for making concrete-like material out of lunar soil. Jennifer Ouellette - Mar 31, 2020 7:30 pm UTC Enlarge / Future moon bases could be built with 3D printers that mix materials such as Moon regolith, water, and astronauts’ urine.Early last year, NASA announced an ambitious…

Study that argued EVs aren’t cleaner gets an update

Scratch that — Redo of 2017 study uses newer data on battery manufacturing. Scott K. Johnson - Dec 4, 2019 7:11 pm UTC There are people who object to newfangled technologies that address our reliance on dirty energy. For them, claims like this are irresistible catnip: electric vehicles aren't actually cleaner than their gas-burning counterparts.…
Study associates frequency, quality of monthly reports with startup success – TechCrunch

Study associates frequency, quality of monthly reports with startup success – TechCrunch

“Despite a lot of publicity and social media, number of sign-ups were modest,” reads one of the last monthly reports I sent to my VCs before my startup ceased to exist. “After the initial wave, sign-ups have slowed right down to near pre-launch levels. User acquisition is our number-one priority and my biggest headache.” Like,…

Study using human brain tissue shows herpes link to Alzheimer’s – STAT

A small 3D version of the human brain develops key features of Alzheimer’s disease when it is infected with a virus that causes cold sores, scientists reported on Wednesday, adding to the evidence that this most common form of dementia can be caused by a common microbe. The new research, published in Science Advances, is…

16 Pages Posted: 22 Jul 2019 Last revised: 22 Aug 2019 Date Written: August 14, 2019 Abstract We show that it is virtually impossible for an individual to day trade for a living, contrary to what course providers claim. We observe all individuals who began to day trade between 2013 and 2015 in the Brazilian…

Physicists study mirror nuclei for precision theory test – Phys.org

A precision measurement of helium and hydrogen mirror isotopes reveals new questions in understanding of nuclear structure. Credit: DOE's Jefferson Lab It's not often in nuclear physics that you can clearly get both sides of the story, but a recent experiment allowed researchers to do just that. They compared very similar nuclei to each other…

Why electric scooters are illegal in New York and London

Spend any time in New York or London, and you’ll inevitably come across dozens of people whizzing along each city’s streets on electric scooters. Yet, despite their popularity, e-scooters are technically illegal in both places, and the politicians with the power to change things are in no rush to do so. In London, e-scooters are…
