Defects aid mother-of-pearl’s assembly, according to new research

Science

Jan. 4 (UPI) -- Scientists have finally uncovered the structural secrets of mother-of-pearl, or nacre, the organic-inorganic composite material that forms the smooth, shiny layer found inside the shells of many mollusk species. According to a new study, published Monday in the journal Nature Physics, structural defects in the material's self-assembly process ensure nacre's incredible uniformity and strength. Advertisement Impressively, mother-of-pearl is the product of a disorganized synthesis process. The process begins when individual cells begin depositing bits of material simultaneously at different locations. During the early stages of construction, the material is not at all uniform. "In the very beginning, the layered mineral-organic tissue is full of structural faults that propag...

Generation Z isn’t all that into lab-grown meat, according to new study

Science

Sept. 8 (UPI) -- All kinds of stakeholders, from environmental activists to venture capitalists, are counting on the growth of the cultured meat market. But new research suggests one of the most important consumer cohorts, Generation Z, isn't ready to eat meat grown from animal cells in a lab. The 2 billion people born between 1995 and 2005 are members of Generation Z, and if businesses are to survive longterm, they must market and sell to them. Advertisement For cultured meat companies marketers, members of Generation Z should be an easy sell. New survey results out of Australia suggest young consumers are especially concerned about climate change, sustainability and animal welfare. "Yet most are not ready to accept cultured meat," Diana Bogueva, researcher at the University of Sydney, s...

Bacteria could survive journey to Mars, according to ISS study

Technology

Bacteria could survive the extreme radiation and temperature fluctuations in the vacuum of space to land on another planet and begin reproducing there, according to a new study.This is one such theory for how life began on Earth, known as panspermia, in which it initially arrived from outer space rather than resulted from self-replicating molecules which naturally developed here on this planet. To prove that microbes could survive in space, Professor Akihiko Yamagishi of the University of Tokyo placed radioresistant Deinococcus bacteria in exposure panels outside of the International Space Station.

Under-20s half as likely to catch coronavirus, according to study

Technology

Under-20s are half as likely to catch COVID-19 as over-20s, making school closures less effective at stopping the spread of the virus, a new scientific study has found.Researchers at the London School of Hygiene and Tropical Medicine found that susceptibility to the coronavirus was low for younger people, before increasing around the age of 20. Nicholas Davies , one of the peer-reviewed paper's co-authors, said there was "a very sharp increase" in COVID-19 susceptibility "somewhere between the ages of 15 and 25".It is not known why this is the case. The results meant school closures were less effective in stopping the spread of coronavirus than other respiratory diseases. ...
