MIT cognitive scientists have found that engaging children in conversation is more critical to their language development than the number of words they hear early in life. In a study of children 4 to 6, they found differences in the number of “conversational turns” accounted for much of the differences in language…
Researchers from Loughborough University, Western General Hospital, the University of Edinburgh, and the Edinburgh Cancer Centre in the United Kingdom, recently developed a deep learning-based method…
A completely new approach suggests the validity of the 110-year-old Lindelöf hypothesis, opening up the possibilities of new discoveries in quantum computing, number theory and cybersecurity
In the past experimentation round Wendelstein 7-X achieved higher temperatures and densities of the plasma, longer pulses and the stellarator world record for the fusion product. Moreover, first confirmation for the optimisation concept on which Wendelstein 7-X is based, was obtained. Wendelstein 7-X at Max Planck…
Neuroscientists at the Picower Institute for Learning and Memory at MIT have discovered that when a synapse strengthens, neighboring synapses weaken based on the action of a crucial protein called Arc. The finding provides an explanation of how synaptic strengthening and weakening combine in neurons to produce…
By 400 BC, Persian engineers had mastered the technique of storing ice in the middle of summer in the desert. The ice was brought in during the winters from nearby mountains in bulk amounts, and stored in a Yakhchal , or ice-pit. These ancient refrigerators were used primarily to store ice for use in the summer, as…
There are large differences in the land of different diets, mostly depending on how much meat people eat.
One year after researchers published their work on a physiological test for autism, a follow-up study confirms its exceptional success in assessing whether a child is on the autism spectrum.
This tipping point — roughly 25% of people — applies to any kind of movement or initiative.

MIT researchers have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.
A study of over 60,000 people who were followed for as long as two decades found that people’s perceptions about their level of activity have a more significant effect on their longevity than the...
A global array of telescopes, including APEX, reveals the finest details so far on event horizon scales in the centre of our Galaxy
AUGUSTA, Ga. – A daily dose of baking soda may help reduce the destructive inflammation of autoimmune diseases like rheumatoid arthritis, scientists say.
How many deaths make a natural disaster newsworthy?
Recently, AI systems have mastered a range of video-games such as Atari classics Breakout and Pong. But as impressive as this performance is, AI still relies on the equivalent of thousands of hours of gameplay to reach and surpass the performance of human video game players. In contrast, we can usually grasp the…
Seaweed could be the key to stopping industrial agriculture from destroying the planet
1. Engineering is done with numbers. Analysis without numbers is only an opinion.
Time crystals — a form of matter that “ticks” when exposed to an electromagnetic pulse — may help to build better atomic clocks, gyroscopes, and quantum tech.
[Note: There is a followup to this post .] There has been a lot written over the past decade (and even longer) about problems associated with null hypothesis statistical testing (NHST) and p values. Personally, I have found most of these arguments unconvincing. However, one of t

Researchers from NVIDIA, led by Guilin Liu, introduced a state-of-the-art deep learning method that can edit images or reconstruct a corrupted image, one that has holes or is missing pixels.
Machine learning algorithms pinpoint new materials 200 times faster than previously possible
