The structure of trefoil metallaknot (Au6(L)3(dppb)3), At6. Separate sections are A the structure (color code: Au, red; P, violet; O, mauve); b the core structures of the enantiomers (H atoms and dppb phenyl groups omitted for clarity); vs the ideal trefoil knots for left and right handed people.

It’s been a good week for the study of human history as a team of anthropologists affiliated with several institutions in the United States, working with a colleague from the National Registry of Peruvian Archaeologists, says that early hunter-gatherer cultures should be renamed “gatherers-gatherers”. hunters,” citing evidence that forage plant matter comprised much more than meat in the diet of early Peruvians. And another team of anthropologists, this one a small international group, has found evidence that syphilis-like illnesses were already widespread in America before Columbus arrived – a finding contrary to stories that Europeans introduced such diseases in the new world, leading to epidemics.
In tech news, a team of engineers from McGill University has discovered that lessons in heat recovery can be learned from the design of Montreal’s Royal Victoria Hospital. By the late 1800s, its designers had found a way to recover heat from exhaust air. And another team of engineers, this one from the Technion’s Faculty of Materials Science and Engineering, has developed new green technology to produce hydrogen using renewable energy. Additionally, a team from the School of Materials Science and Engineering at Guangzhou University, China, has achieved a breakthrough in creating a hypersonic heat shield. They say their porous ceramic creation could be used in aerospace and other applications. And a team from Amazon Web Services’ artificial intelligence lab, working with colleagues at the University of California, discovered that the web is full of faulty machine translations.
Separately, a team led by a UCLA group found evidence that infants born to COVID-infected mothers are three times more likely to develop respiratory distress. And a team of astronomers affiliated with several institutions in the United States and Canada discovered that the moon was shrinking, causing landslides and instability in the lunar south pole region. Additionally, a team of cardiologists in China discovered an association between dark chocolate consumption and reduced risk of essential hypertension. Finally, a trio of chemists from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, working with a colleague from the University of Western Ontario, have made the smallest knot ever, using just 54 atoms .
