and, eventually, pave the way for a better understanding of how life came to be on this planet. We have only probed the effects of temperature and chirality for two αHA systems. The team also observed that variations in the αHA monomer chirality did not result in any clearly observable differences during the dehydration reaction for lactic acid and phenyllactic acid reactions. While polyester microdroplet assembly formation has been demonstrated in controlled conditions in the laboratory, more detailed characterization of this process under a wide range of environmental conditions remains to be explored. Polyester microdroplets can be formed by consecutive dehydration and rehydration following the pre-biotic synthesis of α-hydroxy acid (αHA) monomers, which could have been abundant on early Earth as a result of atmospheric discharge or meteoritic delivery. Scientists have long been fascinated with the origin of life on Earth, namely the transition from simple pre-biotic organic molecules to living cell systems.

The study, published in the journal European Societies, set out to examine academic inequalities among children of migrant origin by looking at the verbal and ...

The speed and scale of recent migration as well as the characteristics of its immigrant population makes Ireland different from many other Western countries. "Our findings show that inequalities are already present at the start of school for some migrant groups, especially for language-related skills. candidate at the Department of Sociology, said, "Classrooms in Ireland have never been more ethnically diverse, and in the last number of months this diversity increased even further with the arrival of thousands of Ukrainian, many of whom do not speak English as a first language. Commenting on the findings, author of the paper Stefanie Sprong, Ph.D. Drawing on data from Growing Up in Ireland (GUI), the national longitudinal study of children, the research found that academic underachievement among migrant groups already exists at the start of school. Children with an Eastern European background tend to have the lowest English skills compared to Irish children.

Seawater might have supplied the phosphorus required for emerging life. Researchers from the Universities of Cambridge and Cape Town may have found a solution ...

Reference: “Marine phosphate availability and the chemical origins of life on Earth” by Matthew P. “If iron helps put more phosphate in solution, then this could have relevance to early Mars,” said Tosca. “It is unusual because it is high in both phosphate and iron — we started to wonder what was so different about those particular waters.” They then built these data points into a model that could predict how much phosphate ancient seawater could hold. “We had a hunch that iron was key to phosphate solubility, but there just wasn’t enough data,” said Tosca. Phosphate is also relatively inaccessible in its mineral form – it can be difficult to dissolve in water so that life can utilize it.

New Zealand's Pyramid Valley has partnered with proof-of-origin specialist Oritain to create a 'fingerprint' linking its wine to specific vineyard sites.

We have always been able to taste the difference – today we can prove it’. This is possible by analysing the specifics of a vineyard site. Bottle labels carry a QR code for drinkers to view the provenance guarantee.
