When rorqual whales feed, they lunge through the water with mouths open wide, taking in vast patches of their tiny prey suspended in a volume of water as big as their massive bodies in one giant gulp. In the process, their mouths experience enormous physical forces. Now, researchers reporting in the journal Current Biology on January 20 have discovered how the whales do this without so much as a choke.

Online food retailers do not consistently display nutrition information on their websites—and U.S. laws are lagging behind in mandating the same labeling required for foods sold in brick-and-mortar stores, according to a new analysis by researchers from the NYU School of Global Public Health and the Friedman School of Nutrition Science and Policy at Tufts University.

A systematic review has found that cannabis use leads to acute cognitive impairments that may continue beyond the period of intoxication.
Mild symptoms, poor knowledge of nearby testing sites, and certain demographic factors have been identified as barriers to COVID-19 testing, according to a new study of more than 4 million adults in the UK published this week in the open-access journal PLOS Global Public Health by Christina M. Astley of Boston Children’s Hospital, US, and colleagues from King’s College London. Testing is a crucial component of the COVID-19 public health response, even as countries roll out vaccination campaigns. In the UK, free PCR COVID-19 tests are offered to people with any of three symptoms: a high temperature, a new, continuous cough, or a change in their sense of smell or taste. However, more than a quarter of people in the UK reporting these symptoms don’t get tested.

A new study of British households finds that, while overall alcohol purchases did not change after COVID-19 lockdown measures began in 2020, purchases did increase for households in socially disadvantaged areas and for households that normally buy more alcohol. Peter Anderson of Newcastle University, England, and colleagues present these findings in the open-access journal PLOS ONE on January 19, 2022.
