MIT researchers have produced the first “laser ultrasound” images in humans, using eye- and skin-safe lasers. The new technique enables noncontact ultrasound imaging, which may help clinicians to remotely assess patients, infants, and contact-sensitive subjects such as burn victims.
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.
The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way — the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years. This panoramic survey of the third-largest galaxy in our Local Group of galaxies provides a mesmerising…
The first time Vayu Maini Rekdal manipulated microbes, he made a decent sourdough bread. At the time, young Maini Rekdal, and most people who head to the kitchen to whip up a salad dressing, pop popcorn, ferment vegetables, or caramelize onions, did not consider the crucial chemical reactions behind these concoctions.
Mitchell J. Feigenbaum , a mathematical physicist whose groundbreaking work on deterministic chaos influenced fields ranging from cardiology to cartography, died in New York City on June 30 at the age of 74. Feigenbaum was the Toyota Professor and director of the Center for Studies in Physics and Biology at…
In this topic page, we explore data on loneliness and social connections and review available evidence on the link between social connections and well-being.
The NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.
Figure 1: ATLAS event display showing the energy deposits of two photons in the electromagnetic calorimeter (green) on opposite sides and no other activity in the detector, which is the clean signature of light-by-light scattering. The Feynman diagram of this process is shown in the lower right corner. (Image: ATLAS…
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…
A pair of new Yale studies confirm that dark matter is not always associated with traditional matter on a galactic scale — which settles a year-long debate.
Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners.
Global demographic transition signals a shift from young, growing populations to older, stable ones, reshaping societies and economies.
As the costs of generating cleaner energy continue to fall, there is growing potential to speed up the transition to a zero-carbon future.
The first formal centre for psychedelic research in the world will launch at Imperial College London today.

Explore data from the United Nations World Population Prospects.
Researchers encode the word “hello” in fabricated DNA, convert it back to digital using fully automated DNA storage system.
Researchers at Brown found that alcohol hijacks a conserved memory pathway in the brain and changes which versions of genes are made, forming the cravings that fuel addiction.
Engineering professor Nader Engheta and his team have demonstrated a metamaterial device that can function as an analog computer, validating an earlier theory about ‘photonic calculus.’
New research from Washington University in St. Louis confirms that the brain tunes itself to a point where it is as excitable as it can be without tipping into disorder, similar to a phase transition. The new research from Keith Hengen, assistant professor of biology in Arts & Sciences, is published Oct. 7 in the…
What is the age profile of populations around the world? How did it change and what will the age structure of populations look like in the future?
UW researchers created a method for two people help a third person solve a task using only their minds.
Case Western Reserve researchers observe waves ‘leap’ across cut in brain tissue; ‘ephaptic coupling’ said to be producing self-propagating wa...
