Multi-screening may mess with your memory

  • A new study by Stanford University researchers, published in the journal Nature, has shed more light on this by linking attention lapses in habitual media multi-taskers to poorer memory.
  • While it’s logical that fluctuations in attention relate to learning, memory and media multi-tasking, surprisingly little research has explored whether the things we do before we remember might have an impact, according to lead author Kevin Madore.
  • With a team of researchers, including senior author Anthony Wagner, Madore used a novel method of assessing sustained attention by recording pupil size and brain activity.
  • Results showed that attention lapses in the moment prior to remembering impacted on behavioural and neural memory signals and were associated with greater likelihood of forgetting.
  • They also suggest that sustained attention ability – which was poorer in heavy media multitaskers – may go some way toward explaining why some people have better memories than others, says Madore.

Arctic sea ice loss could trigger huge levels of extra global warming

  • If Arctic sea ice vanishes in summers by the middle of the century as expected, the world could see a vicious circle that drives enough global warming to almost wipe out the impact of China going carbon neutral.
  • To answer it, Ricarda Winkelmann at the Potsdam Institute for Climate Impact Research in Germany and her colleagues modelled the impact of such feedbacks on global temperature rises if ice disappeared from mountain glaciers, the Greenland and West Antarctica ice sheets, and the Arctic in summer.
  • They found that the loss of ice in all four places would, over centuries to millennia, contribute an extra 0.43°C of warming globally in the event of the world holding temperature rises to 1.5°C.
  • The Arctic feedbacks would have an even bigger impact locally, raising temperatures 1.5°C in a region that is warming faster than the rest of the world and beset by record fires.

WHO: Controlling COVID-19 needs personal sacrifice, tough restrictions - Business Insider

  • His warning came as COVID-19 cases surged, particularly in the US and Europe.
  • WHO officials said some countries may have to consider closing down non-essential businesses again to stem the tide.
  • The WHO also criticized some nations for not doing enough to reduce the spread of the virus during the first wave of the pandemic.
  • But WHO officials said Monday that the coronavirus is starting to "leak" into older and more vulnerable populations.
  • The statements from the WHO come as COVID-19 cases are surging.
  • Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, warned Sunday that the US is "going on the wrong direction" on COVID-19 following record daily rises.
  • France also recorded its own record daily rise in cases on Sunday, with 52,000 new cases.
  • On October 22, Spain and France became the first European countries to pass 1 million cases.

40,000 Square Kilometers of the Lunar Surface Can Hold Water

  • The abundance of small-scale cold traps implies that future missions exploring for ice may more easily target and access one of these potential reservoirs.
  • If water is found in micro cold traps, the sheer number and topographic accessibility of these locales would facilitate future human and robotic exploration of the Moon.
  • Here, we show that many unmapped cold traps exist on small spatial scales, substantially augmenting the areas where ice may accumulate.
  • Using theoretical models and data from the Lunar Reconnaissance Orbiter, we estimate the contribution of shadows on scales from 1 km to 1 cm, the smallest distance over which we find cold-trapping to be effective for water ice.
  • Consideration of all spatial scales therefore substantially increases the number of cold traps over previous estimates, for a total area of ~40,000 km2, about 60% of which is in the south.
