Southwest Research Institute scientists modeled the mixing of materials associated with these impacts, revealing that the Red Planet may have formed over a longer timescale than previously thought.

Nature, Published online: 12 February 2020; doi:10.1038/s41586-020-1998-1 Glycolysis in normal epithelial cells responds to microenvironmental mechanics via the modulation of actin bundles that sequester the phosphofructokinase-targeting ubiquitin ligase TRIM21, a process superseded by persistent actin bundles in cancer cells.

One of the central questions in neuroscience is clarifying where in the brain consciousness, which is the ability to experience internal and external sensations, arises.

Marina bakteriers genuttryck kan vara en värdefull sensor för att upptäcka miljöförändringar orsakade av oss människor. Bakterierna hjälper dessutom till att rena haven och på sikt kan de förhoppningsvis rena dricksvatten från skadliga miljögifter, menar forskare marinekologi vid Linnéuniversitetet. Marina bakterier finns i stor mängd i alla marina ekosystem, där de som nedbrytare av organiskt ma

Journals retract 13 papers by Hans Eysenck, flag 18, some 60 years old
Two journals have retracted 13 papers co-authored by the late — and controversial — psychologist Hans Eysenck, following a university investigation that found dozens of his papers to be "unsafe." One of the journals, Perceptual and Motor Skills, subjected eight of Eysenck's papers to expressions of concern, while another — Psychological Reports — subjected 10 … Continue reading

John Locke vs. John Stuart Mill: Using metaethics to examine claims
There are two schools of thought when it comes to liberalism and rights: John Locke's naturalistic point of view, and John Stuart Mill's moralistic/utilitarian stance. Locke believed that right and wrong could be determined rationally, while Mill believed in moral rules and the idea that what's right and wrong should be in service of human happiness. Philosophy professor Daniel Jacobson argues th

ATM and PRDM9 regulate SPO11-bound recombination intermediates during meiosis
Nature Communications, Published online: 12 February 2020; doi:10.1038/s41467-020-14654-w Recombination requires DNA break formation by SPO11, following which SPO11 is thought to be released. Here, the authors show that meiotic hotspots retain SPO11 through a recombination intermediate dependent on the methyltransferase PRDM9, and that the ATM kinase governs the release of SPO11.
