A reluctant Catherine de Lange tries tempering for the first time and discovers how to make gloriously glossy chocolate to decorate a cake with

Watching US politicians and former generals as they react to a simulated attempted coup after a disputed US election in the documentary War Game is fascinating – but it leaves many questions unanswered, finds Bethan Ackerley

The veteran presenter adds authority to Secret Lives of Orangutans, a film about a family of endangered orangutans in Sumatra. File this new entry in his vast oeuvre under lovable but lightweight

After 25 years in orbit, the Chandra X-ray Observatory is under threat. We need to protect this monument to human ingenuity, argues Chanda Prescod-Weinstein

A curious Feedback delves further into the invention of the Morbid Curiosity Scale and discovers how it might help with certain "short-term mating goals"

Our ability to exert conscious control over our family sizes is unique – and can be transformational, says Christopher Wills

James Lovelock's hypothesis that our planet is a living entity is well known. Ferris Jabr's new book Becoming Earth takes it a step further

For the first time, climate scientists have explicitly said it will be impossible to limit peak warming to 1.5°C. Now our focus should be on taking action, not meaningless platitudes and slogans

In today’s Jesus and Mo strip, called “ends,” Mo talks himself into a rhetorical corner but, as always, fails to realize it.

In children aged 6 to 11, long covid seems to often present as sleep problems or abdominal issues, while adolescents report fatigue and pain

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons, the findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical engineering.

Researchers have succeeded in forming metal-organic framework thin films on a substrate while controlling the growth direction of crystals so that they are arranged neatly without gaps. The resulting thin films of unprecedented high quality can be expected for use as optical sensors, optical elements, and transparent gas adsorption sheets.

Researchers have developed an eco-friendly refrigeration device with record-breaking cooling performance in the world, setting to transform industries reliant on cooling and reduce global energy use. With a boost in efficiency of over 48%, the new elastocaloric cooling technology opens a promising avenue for accelerating the commercialization of this disruptive technology and addressing the environmental challenges associated with traditional cooling systems.

A new model accurately represents the airflow around rotors, even under extreme conditions. The first comprehensive model of rotor aerodynamics could improve the way turbine blades and wind farms are designed and how wind turbines are controlled.

The innovative strength of a society depends on the level of academic freedom. An international team has now demonstrated this relationship. The researchers analyzed patent applications and patent citations in a sample from around 160 countries over the 1900--2015 period in relation to indicators used in the Academic Freedom Index. In view of the global decline in academic freedom over the past 10 years, the researchers predict a loss in innovative output.

Lithium iron phosphate is one of the most important materials for batteries in electric cars, stationary energy storage systems and tools. It has a long service life, is comparatively inexpensive and does not tend to spontaneously combust. Energy density is also making progress. However, experts are still puzzled as to why lithium iron phosphate batteries undercut their theoretical electricity storage capacity by up to 25 per cent in practice.

An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.

New fusion simulations of the inside of a tokamak reveal the ideal spot for a 'cave' with flowing liquid lithium is near the bottom by the center stack, as the evaporating metal particles should land in just the right spot to dissipate excess heat from the plasma.
