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.
This is part 4 of an intermittent yet always enjoyable series: • Part 1: the rise of the ancient Puebloan civilization in the American Southwest from 10,000 BC to 750 AD. • Part 2: the rise and col…
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.
I recently became aware of this article where a Google exec says - he’s serious - that ‘Nest owners should probably warn their guests that their conversations are being recorded’. That’s assuming the owners themselves are even aware of what these devices are doing, and the likely truth is that they do not. Like needy…
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.
This is what our night sky is going to look like in 3.9 billion years: Wow! So what’s going on here? Using data from the Hubble Space Telescope, astronomers at
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.

We all know what sound is. Except actually, no we don't. Let's fix that.
There is, apparently, an increase recently in interest in the Dunning-Kruger effect. The Washington Post writes about this recently, making the obvious political observation (having to do with the current occupant of the White House). It's great that there is public interest in an important psychological phenomenon…
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.’
