Kaili Rimfeld et al. Genetic influence on social outcomes during and after the Soviet era in Estonia, Nature Human Behaviour (2018). DOI: 10.1038/s41562-018-0332-5

>The aetiology of individual differences in educational attainment and occupational status includes genetic as well as environmental factors and can change as societies change. The extent of genetic influence on these social outcomes can be viewed as an index of success in achieving meritocratic values of equality of opportunity by rewarding talent and hard work, which are to a large extent influenced by genetic factors, rather than rewarding environmentally driven privilege. To the extent that the end of the Soviet Union and the independence of Estonia led to an increase in meritocratic selection of individuals in education and occupation, genetic influence should be higher in the post-Soviet era than in the Soviet era. Here we confirmed this hypothesis: DNA differences (single-nucleotide polymorphisms) explained twice as much variance in educational attainment and occupational status in the post-Soviet era compared with the Soviet era in both polygenic score analyses and single-nucleotide polymorphism heritability analyses of 12,500 Estonians. Our results demonstrate a change in the extent of genetic influence in the same population following a massive and abrupt social change—in this case, the shift from a communist to a capitalist society.

Quantum simulation of the integer factorization problem: Bell states in a Penning trap, Physical Review A (2018). DOI: 10.1103/PhysRevA.97.032325, arXiv: 1704.03174

>The arithmetic problem of factoring an integer N can be translated into the physics of a quantum device, a result that supports Pólya's and Hilbert's conjecture to demonstrate Riemann's hypothesis. The energies of this system, being univocally related to the factors of N, are the eigenvalues of a bounded Hamiltonian. Here we solve the quantum conditions and show that the histogram of the discrete energies, provided by the spectrum of the system, should be interpreted in number theory as the relative probability for a prime to be a factor candidate of N. This is equivalent to a quantum sieve that is shown to require only o(ln√N)³ energy measurements to solve the problem, recovering Shor's complexity result. Hence the outcome can be seen as a probability map that a pair of primes solve the given factorization problem. Furthermore, we show that a possible embodiment of this quantum simulator corresponds to two entangled particles in a Penning trap. The possibility to build the simulator experimentally is studied in detail. The results show that factoring numbers, many orders of magnitude larger than those computed with experimentally available quantum computers, is achievable using typical parameters in Penning traps.

tl;dr or tt;du (too technical; didn't understand): we can estimate which prime factors are more likely using a quantum simulator, and this is a workaround for breaking RSA encryption which is based exactly on the computational difficulty of that problem to classical methods.

How strong was the bottleneck associated to the peopling of the Americas? New insights from multilocus sequence data. Genetics and Molecular Biology (2018). DOI: 10.1590/1678-4685-gmb-2017-0087

>In spite of many genetic studies that contributed for a deep knowledge about the peopling of the Americas, no consensus has emerged about important parameters such as the effective size of the Native Americans founder population. Previous estimates based on genomic datasets may have been biased by the use of admixed individuals from Latino populations, while other recent studies using samples from Native American individuals relied on approximated analytical approaches. In this study we use resequencing data for nine independent regions in a set of Native American and Siberian individuals and a full-likelihood approach based on isolation-with-migration scenarios accounting for recent flow between Asian and Native American populations. Our results suggest that, in agreement with previous studies, the effective size of the Native American population was small, most likely in the order of a few hundred individuals, with point estimates close to 250 individuals, even though credible intervals include a number as large as ~4,000 individuals. Recognizing the size of the genetic bottleneck during the peopling of the Americas is important for determining the extent of genetic markers needed to characterize Native American populations in genome-wide studies and to evaluate the adaptive potential of genetic variants in this population.

This was more of a scholarly article sharing thread. You probably don't know but we had a /campus/ board before but that was really really dead with mostly just me samefagging, and this thread was salvaged from there.

>Land change is a cause and consequence of global environmental change. Changes in land use and land cover considerably alter the Earth’s energy balance and biogeochemical cycles, which contributes to climate change and—in turn—affects land surface properties and the provision of ecosystem services. However, quantification of global land change is lacking. Here we analyse 35 years’ worth of satellite data and provide a comprehensive record of global land-change dynamics during the period 1982–2016. We show that—contrary to the prevailing view that forest area has declined globally—tree cover has increased by 2.24 million km² (+7.1% relative to the 1982 level). This overall net gain is the result of a net loss in the tropics being outweighed by a net gain in the extratropics. Global bare ground cover has decreased by 1.16 million km² (−3.1%), most notably in agricultural regions in Asia. Of all land changes, 60% are associated with direct human activities and 40% with indirect drivers such as climate change. Land-use change exhibits regional dominance, including tropical deforestation and agricultural expansion, temperate reforestation or afforestation, cropland intensification and urbanization. Consistently across all climate domains, montane systems have gained tree cover and many arid and semi-arid ecosystems have lost vegetation cover. The mapped land changes and the driver attributions reflect a human-dominated Earth system. The dataset we developed may be used to improve the modelling of land-use changes, biogeochemical cycles and vegetation–climate interactions to advance our understanding of global environmental change.

was looking at tidal amplitude maps,
realized something was wrong.
tides can't be caused by moon if these maps are correct.
checked tide times in/out with a few locals, found some webcams, yep, can't be moon.

not a peep from universities, all blame moon for tides.

only conspiracy-tier folks actually presenting correct info on the subject of tides:

have you been sea pilled?

explanation how tides work: oceans work like resonators. Then you have external forces driving this resonator (protip: it's mostly Moon and Sun). Some bays and channels have eigenfrequencies close to 24h (for example, English Channel), and for that reason the driving is resonant there. But besides the tides, sea basins also oscillate in their own eigenfrequencies, not aligned to the 24h called "tides". For mechanism look up Kelvin waves.
tidal lock is fake

but the real red pill is when you realize gravity is a hoax
