The article discusses the study of Ulli Eichman and colleagues of Max Born Institute in Berlin, Germany on the acceleration of neutral atoms using a strong laser pulse. It notes that Eichman and colleagues have used helium atoms in their experiment because of its atomic featherweight that can easily be push around with strong forces, and reveals that it has survived the strong laser. It mentions that its survival was because of the ability of helium's electron to oscillate near its ionic core.

The article provides information on a study on the spatial memory of the flies conducted by a group of German researchers lead by Ronald Strauss of the Johannes Gutenberg University in Mainz, Germany. It mentions that the ability of the flies to choose how to navigate their surroundings depend on their capacity for short-term, spatial memory. Strauss and his colleagues built a virtual reality fly arena to investigate whether the flies have brain. The wings of the flies were clipped and they were surrounded by a water moat. The result of the study suggests that the capacity of the flies for short-term memory is comparable to that of humans.

The article cites study conducted by Jan Born and his colleagues in Germany on how electrical oscillations during sleep help people remember things. It has been noted that oscillations in electrical activity occur at varying rates of the sleep cycle, with peak activity during rapid-eye-movement sleep and lowest during deep sleep. The study found that the neocortex created a more pronounced slow wave oscillations after stimulation.

The article reports that life in the freezer is about to become a reality for thousands of ancient books in eastern Germany. The books form part of the Duchess Anna Amalia Library in Weimar, one of Europe's most valuable collections, which was badly damaged by fire on 2 September. Some 30,000 of the million volumes in the library's collection were destroyed in the blaze. And at least 40,000 burnt and water-logged books and manuscripts now need to be restored. The damaged books are being taken to the Centre for Book Conservation in Leipzig, where they will be stored below minus 22 degree centigrade to keep mould and bacteria at bay. They will then be freeze-dried before restoration begins. The federal government has pledged 4 million to kick-start the effort, and private donations are already coming in to help complete it.

However, David Leopold claimed that Logothetis is just hindering them to publish the data for his own good.

- Abstract
Long-term analyses of biodiversity data highlight a 'biodiversity conservation paradox': biological communities show substantial species turnover over the past century
1,2 , but changes in species richness are marginal1,3-5 . Most studies, however, have focused only on the incidence of species, and have not considered changes in local abundance. Here we asked whether analysing changes in the cover of plant species could reveal previously unrecognized patterns of biodiversity change and provide insights into the underlying mechanisms. We compiled and analysed a dataset of 7,738 permanent and semi-permanent vegetation plots from Germany that were surveyed between 2 and 54 times from 1927 to 2020, in total comprising 1,794 species of vascular plants. We found that decrements in cover, averaged across all species and plots, occurred more often than increments; that the number of species that decreased in cover was higher than the number of species that increased; and that decrements were more equally distributed among losers than were gains among winners. Null model simulations confirmed that these trends do not emerge by chance, but are the consequence of species-specific negative effects of environmental changes. In the long run, these trends might result in substantial losses of species at both local and regional scales. Summarizing the changes by decade shows that the inequality in the mean change in species cover of losers and winners diverged as early as the 1960s. We conclude that changes in species cover in communities represent an important but understudied dimension of biodiversity change that should more routinely be considered in time-series analyses., (© 2022.

- Abstract
The history of the British Isles and Ireland is characterized by multiple periods of major cultural change, including the influential transformation after the end of Roman rule, which precipitated shifts in language, settlement patterns and material culture
1 . The extent to which migration from continental Europe mediated these transitions is a matter of long-standing debate2-4 . Here we study genome-wide ancient DNA from 460 medieval northwestern Europeans-including 278 individuals from England-alongside archaeological data, to infer contemporary population dynamics. We identify a substantial increase of continental northern European ancestry in early medieval England, which is closely related to the early medieval and present-day inhabitants of Germany and Denmark, implying large-scale substantial migration across the North Sea into Britain during the Early Middle Ages. As a result, the individuals who we analysed from eastern England derived up to 76% of their ancestry from the continental North Sea zone, albeit with substantial regional variation and heterogeneity within sites. We show that women with immigrant ancestry were more often furnished with grave goods than women with local ancestry, whereas men with weapons were as likely not to be of immigrant ancestry. A comparison with present-day Britain indicates that subsequent demographic events reduced the fraction of continental northern European ancestry while introducing further ancestry components into the English gene pool, including substantial southwestern European ancestry most closely related to that seen in Iron Age France5,6 ., (© 2022.

The article reports on the study conducted by researchers Irene Stemmler and Gerhard Lammel of the Max Planck Institute for Chemistry regarding the environmental effects of dichlorodiphenyltrichloroethane (DDT) in Mainz, Germany. The researchers found that DDT may have accumulated in large amounts to oversaturate the surface waters and be re-emitted into the atmosphere. Using a three-dimensional atmosphere-ocean global circulation model, the researchers found that the western North Atlantic ocean has been re-emitting DDT for more than three decades, longer that most other regions. They also suggests that the distribution of the pesticide has been creeping northwards.

GENETIC genealogy ,ANCESTORS ,GENOMICS ,GENEALOGY - Abstract
We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these populations' deep relationships and show that early European farmers had ∼44% ancestry from a 'basal Eurasian' population that split before the diversification of other non-African lineages.

The paper made headlines because such pluripotent stem cells may be used rather than ethically sensitive human embryonic tissue.

ARCHAEOLOGICAL finds ,BONE flute ,AURIGNACIAN culture ,NEANDERTHALS ,ARCHAEOLOGICAL research - Abstract
Considerable debate surrounds claims for early evidence of music in the archaeological record. Researchers universally accept the existence of complex musical instruments as an indication of fully modern behaviour and advanced symbolic communication but, owing to the scarcity of finds, the archaeological record of the evolution and spread of music remains incomplete. Although arguments have been made for Neanderthal musical traditions and the presence of musical instruments in Middle Palaeolithic assemblages, concrete evidence to support these claims is lacking. Here we report the discovery of bone and ivory flutes from the early Aurignacian period of southwestern Germany. These finds demonstrate the presence of a well-established musical tradition at the time when modern humans colonized Europe, more than 35,000 calendar years ago. Other than the caves of the Swabian Jura, the earliest secure archaeological evidence for music comes from sites in France and Austria and post-date 30,000 years ago. [ABSTRACT FROM AUTHOR]
