Acoustic levitation used to build complex structures in mid-air:
Sound waves have been used to build complex structures in mid-air out of floating components and droplets of glue, showing the approach may have engineering and medical applications
'Shocking' failure to insulate homes means UK will miss carbon goals:
Independent Climate Change Committee criticises the UK government over energy efficiency and agriculture policies, but praises action on electric cars
AI that detects chicken distress calls could improve farm conditions:

Intermittent fasting linked to better gut and liver function in mice:
Limiting meals to an eight-hour window each day regulates the circadian rhythm of multiple organs in mice, potentially staving off chronic disease
Algae cells that cheat are more likely to die of environmental stress:
Cheaters never win – at least in algae. Cells modified to reproduce when they shouldn't are more vulnerable to changes in the environment. This tradeoff could help explain the emergence of multicellular organisms, and what prevents our cells from rebelling ag…
Tiny nanoturbine is an autonomous machine smaller than most bacteria:
A turbine only a few dozen nanometres in size made from DNA rotates in salty water without having to be pushed which makes it a tiny autonomous machine. It could be for speeding up chemical reactions or transporting particles inside cells
Why elite universities like Cambridge must ditch big oil funding:
While institutions like Cambridge talk up climate action, they also maintain partnerships with the fossil fuel giants driving climate catastrophe. This must stop, says Zak Coleman
What is the Hertzbleed computer chip hack and should you be worried?:
A new hack called Hertzbleed can read snippets of data from computer chips remotely and could leave cryptography algorithms vulnerable to attack
Europe must tackle its energy crisis now or face a very painful winter:
With energy prices set to rise, European governments must act immediately to reduce consumption and turbocharge renewables
Zero-covid strategies are being ditched, but they were the best option:
Several countries are now abandoning their goal of reducing the coronavirus's spread as much as possible, but the evidence shows this was the best route to have taken, says Michael Marshall
