We are used to heat flowing from hot objects to cool ones, and never the other way round, but now researchers have found it is possible to pull off this trick in the strange realm of quantum mechanics

If plans by the UK’s science funding body go ahead, we won’t be able to benefit from Britain’s membership of Cern and other large international projectsAlarm bells are ringing in the UK research community. Physics departments may close and researchers leave the UK. What is happening and why?The alarm comes from changes in the way taxpayers’ money is invested by UK Research and Innovation (UKRI), which recently published its plan on how to disburse £38.6bn of public research and development funding over the next four years. Change is always unsettling, and as the UKRI’s chief executive, Ian Chapman, says, there will always be those who lose out when change happens. Difficult choices must be made.Jon Butterworth is professor of physics at University College London, and a member of the ATLAS Collaboration at Cern Continue reading...

Cells constantly monitor and recycle their proteins through a tightly regulated waste-disposal system. Proteins that are no longer needed are tagged and broken down by specialized cellular machinery. Recent advances in drug discovery seek to exploit this system by redirecting it toward disease-relevant targets. This strategy relies on so-called molecular glues, small molecules that induce interactions between proteins that would not normally bind to each other. If a disease-causing protein can be brought into contact with a cellular degradation enzyme, it is selectively eliminated by the cell itself. Until now, however, most molecular glues have been discovered by chance, limiting their broader therapeutic application.

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar cells, the industry standard. In a new study published in Nature Communications, physicists at the Institute of Science and Technology Austria (ISTA) present a comprehensive explanation of the mechanism behind perovskite efficiency that has long perplexed researchers.
