When mice learn to do a new task, their brain activities change over time as they advance from ‘novice’ to ‘expert.’ The changes are reflected in the wiring of cell circuits and activities of neurons. Using a two-photon imaging microscope and a wealth of genetic tools, researchers from Cold Spring Harbor Laboratory…
Self-reported life satisfaction differs widely between people and between countries. What explains these differences?
Microsoft and Warner Brothers collaborate to store and retrieve the 1978 'Superman' movie on a piece of glass roughly the size of a drink coaster.
Rochester researchers have created a metallic structure so water repellent, it refuses to sink—no matter how often it is forced into water.
TROY, N.Y. — Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally.
How is humanity using the Earth’s land? And how can we decrease our land use so that more land is left for wildlife?
More than half of the world is online, but the Internet is still young.
We are at the beginning of a new era, where biology has shifted from an empirical science to an engineering discipline. After a millennia of using man-made approaches for controlling or manipulating biology, we have finally begun using nature’s own machinery—through biological engineering—to design, scale, and…

This study examines how vehicle speed influences the probability that a pedestrian struck by a vehicle will sustain severe injuries or die.
We argue that an ideal simulation of the same task can be performed on a classical system in 2.5 days and with far greater fidelity.

Antarctic ice cliffs may not contribute to sea-level rise as much as once thought: An MIT study finds even the tallest ice cliffs are unlikely to collapse catastrophically and trigger a runaway ice sheet retreat.
This memoir of a near-fatal mushroom poisoning was written by our most fortunate guest, Richard Eshelman. Happy Thanksgiving, all.
MIT engineers have analyzed a bridge design proposed by Leonardo da Vinci, and found that it would indeed have stood solidly, had it ever been built.
Scientists have discovered molecules that inhibit tumor growth by starving cancer cells of their favorite foods: the sugar glucose and the amino acid, glutamine.
Damages from air pollution have fallen dramatically in the U.S. in recent years, shows new research. But how different sectors of the economy have contributed to that decline is highly uneven.
The Nobel Prize in Physics 2019 was awarded "for contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos" with one half to James Peebles "for theoretical discoveries in physical cosmology", the other half jointly to Michel Mayor and Didier Queloz "for the discovery of an…
MINNEAPOLIS – Young adults who experience annual income drops of 25 percent or more may be more at risk of having thinking problems and reduced brain health in middle age, according to a study published in the October 2, 2019, online issue of Neurology ® , the medical journal of the American Academy of Neurology …
In the largest study of its kind, results challenge the notion of autism as reflecting an “extreme male brain.”
A new type of vaccine that can be stored at warmer temperatures, removing the need for refrigeration, has been developed for mosquito-borne virus Chikungunya in a major advance in vaccine technology. The findings, published in Science Advances today [Wednesday 25 September], reveal exceptionally promising results for…
The world needs ideas and innovation to make progress. Creative and talented people are everywhere, but the opportunity to develop is limited to only a small number of well-off children. The world loses out as a result.
