put it to the test

GREGOR MENDEL had his pea plants. Ivan Pavlov had his dogs. At New Scientist, we have our staff, and every so often we like to experiment on ourselves – in pursuit of greater knowledge, of course. Perhaps our most triumphant episode of self-experimentation came in November 2013, when 14 of our staff trooped into a London hospital looking unusually sober. A doctor told them: “You’re going to be very excited.” For the previous month, they had been part of a pilot study to test whether a month off alcohol – Dry January as public health groups promote it – could really make a difference to your health. The results were surprisingly stark: scans showed that liver fat, whose build-up can damage the organ, dropped by 15 per cent on average among the…

spacecraft goes awry

BOEING’s Starliner spacecraft has faced a rough start. A software issue during launch meant it didn’t supply the International Space Station as planned. It isn’t yet clear what this will mean for US plans for crewed space flight. The issue started before launch when Starliner’s software latched onto the wrong clock to set its time. Nobody noticed this and its clock was 11 hours off what was intended as a result. About 31 minutes after Starliner launched, it fired its thrusters too early, using up fuel it needed to reach the ISS. So the Boeing team had to bring the craft back down for a landing in New Mexico on 22 December, which went smoothly. During the landing, the spacecraft endured temperatures upwards of 1600°C. This was a crucial part of the…

delay to ozone recovery expected

THE permanent closure of the ozone hole over Antarctica is likely to be delayed by the illegal production of the gas CFC-11 in China. The ozone hole, which is usually open between September and November, is expected to recover by around 2060. But a modelling study now suggests that, in the worst case scenario, ozone recovery will be delayed by 18 years if the production of trichlorofluoromethane (CFC-11), used to make fridge insulation, continues unabated. “The ozone hole over Antarctica is expected to recover by around 2060” But such an extreme scenario is unlikely as there are signs that authorities in China have begun cracking down on the problem. If production is phased out over the next decade, which seems more likely, the result would be a two-year delay in ozone recovery, says…

endometriosis clue

ONE IN 10 women live with endometriosis, but we still don’t know its exact cause. New evidence suggests that some cases may be present from birth, and that different subtypes of the condition may benefit from different treatments. Endometriosis is diagnosed when endometrial cells from the lining of the uterus are found elsewhere in the body. When people with the condition menstruate, these patches of cells, wherever they are, bleed. This is thought to be at least partly responsible for the debilitating pain people with endometriosis often experience, although we still don’t really know. Those affected often find it harder to conceive, too. One of the more established ideas to explain what causes endometriosis suggests that these rogue cells are the product of “retrograde menstruation”. The idea is that some menstrual blood…

police could identify illegal drugs with magnetic levitation

A DEVICE that uses a form of magnetic levitation to separate components of illegal drugs could be useful in the fight against crime. Street drugs are often a mixture of substances, and police forces need to be able to identify exactly what they contain in order to enforce the law. The new approach to this problem, devised by Christoffer Abrahamsson at Harvard University and his colleagues along with the US Drug Enforcement Administration, involves adding a drug sample to a magnetic liquid and placing this mixture in a container with magnets at its top and bottom. The thermos flask-sized device, which only costs around $200 to build, separates components of the sample by their respective densities. The magnetic liquid attempts to push particles of drugs away from the magnets in order to minimise…
