Russia’s invasion is the latest threat to the stability of world food supplies. Researchers must act now to halt the cycle of repeated food crises.
Iranian researchers are at risk as never before. Governments are urging quiet diplomacy. But a new book shows why public campaigns matter.
Data from an old experiment find that the mass of the W boson is higher than theory predicts, hinting at future breakthroughs.
Many Western nations are severing scientific links — but it’s a different story in China, India and South Africa.
Based on more than 120,000 brain scans, the charts are still preliminary. But researchers hope they could one day be used as a routine clinical tool by physicians.
Studies have revealed that infected immune cells prompt a massive inflammatory response.

Analysis of climate pledges by nations at the COP26 meeting indicates that such commitments could ensure that global warming does not exceed 2 ºC before 2100 — but only if backed up by short-term policies.
Skin cells called melanocytes are not equally affected by the same genetic changes. Their ability to form tumours has now been linked to gene-expression programs that are selectively activated according to a cell’s anatomical position.
Plasmids — circular DNA molecules — are found in many bacteria, and carry genes that can give the host microorganism new features. The mystery of how a cholera-causing bacterium eliminates plasmids has now been solved.
The polarization, wavelength and power of a light wave can be simultaneously identified by a compact device made from twisted layers of carbon atoms — with a little help from an artificial neural network.
Chemical synthesis often relies on reactions catalysed by transition metals. Electrochemical methods have now been developed that negate this need, opening up pathways to previously challenging reactions.
