We Are Beast Machines – Issue 107: The Edge17h
I have a childhood memory of looking in the bathroom mirror, and for the first time realizing that my experience at that precise moment—the experience of being me—would at some point come to an end, and that "I" would die. I must have been about 8 or 9 years old, and like all early memories this one too is unreliable. But perhaps it was at this moment that I also realized that if my consciousness
Neuroscience Weighs in on Physics' Biggest Questions – Issue 107: The Edge17h
For an empirical science, physics can be remarkably dismissive of some of our most basic observations. We see objects existing in definite locations, but the wave nature of matter washes that away. We perceive time to flow, but how could it, really? We feel ourselves to be free agents, and that's just quaint. Physicists like nothing better than to expose our view of the universe as parochial. Whi
The Spiritual Consciousness of Christof Koch – Issue 107: The Edge17h
Consciousness is a thriving industry. It's not just the meditation retreats and ayahuasca shamans. Or the conferences with a heady mix of philosophers, quantum physicists, and Buddhist monks. Consciousness is a buzzing business in neuroscience labs and brain institutes. But it wasn't always this way. Just a few decades ago, consciousness barely registered as a credible subject for science. Perhap

Solving mystery of rare cancers directly caused by HIV•20h
STAT3 LCK Mystery HIV
For nearly a decade, scientists have known that HIV integrates itself into genes in cells that have the potential to cause cancer.

A new study reveals why doctors aren't seeing high rates of T cell lymphomas — or

Den 15 september år 2008 gick den amerikanska investmentbanken Lehman Brothers i konkurs. En finanskris drabbade världen. Centralbanker och regeringar pumpade in tusentals miljarder kronor för att rädda banksystem och ländernas ekon
Facing Rising Violence, Hospital Workers Speak Out1d
Workplace violence has always been a problem for hospitals. But as the Covid-19 pandemic marches on, nurses and other health care workers say the issue is getting worse. Many are now seeking nationwide standards for protection, going beyond those offered at the individual hospital level.
Klimaforskning: Én procent gør en verden til forskel1d
Frikk Nesje og hans kolleger har skabt international opmærksomhed ved at bygge bro i debatten om,…
MesoNet allows automated scaling and segmentation of mouse mesoscale cortical maps using machine learning1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26255-2 High content imaging of the brain holds the promise of improving our understanding of the brain's circuitry. Here, the authors present a tool that automates the scaling and segmentation of cortical maps to accelerate neurobiological discovery using mesoscale images.
Direct on-swab metabolic profiling of vaginal microbiome host interactions during pregnancy and preterm birth1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26215-w Here, the authors apply DESI-MS, a sample preparation-free, direct on-swab mass spectrometry analytical tool, to profile the cervicovaginal metabolome of two independent cohorts of pregnant women and, combined with matched metataxonomic and immuno-profiling data, show that DESI-MS predicts vaginal microbiota
Exposure to 16 h of normobaric hypoxia induces ionic edema in the healthy brain1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26116-y Prolonged hypoxia, which can be due to stroke or ascent to high altitude, can lead to cerebral edema. Here, the authors used a combination of sodium and proton MRI and experimentally induced hypoxic conditions to identify the cause for brain swelling: Ionic edema, an intermediate between cytotoxic and vasogen
A self-healing catalyst for electrocatalytic and photoelectrochemical oxygen evolution in highly alkaline conditions1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26281-0 While self-healing catalysts may survive the harsh environments used for oxygen evolution, understanding how to develop such electrocatalysts remains a challenge. Here, authors find cobalt to promote the self-healing of leached iron centers in borate-intercalated nickel-iron-cobalt oxyhydroxides.
Phase separation of Nur77 mediates celastrol-induced mitophagy by promoting the liquidity of p62/SQSTM1 condensates1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26295-8 How phase separation participates in mitophagy remains unclear. Here the authors show that Nur77 and p62/SQSTM1 through "head-to-head" and "tail-to-tail" interactions form membraneless condensates capable of sequestering dysfunctional mitochondria and tethering them to autolysosome for degradation.
Primary visual cortex straightens natural video trajectories1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-25939-z Many behaviours depend on predictions about the environment. Here the authors find neural populations in primary visual cortex to straighten the temporal trajectories of natural video clips, facilitating the extrapolation of past observations.
BRCA2 associates with MCM10 to suppress PRIMPOL-mediated repriming and single-stranded gap formation after DNA damage1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26227-6 Tumor suppressor BRCA2 is known to stabilize and restart stalled DNA replication forks. Here the authors show that BRCA2 is recruited to the replication fork through its interaction with MCM10 and inhibits Primase-Polymerase-mediated repriming, lesion bypass and single strand DNA gap formation after DNA damag
Shear relaxation governs fusion dynamics of biomolecular condensates1d
Nature Communications, Published online: 13 October 2021; doi:10.1038/s41467-021-26274-z Phase-separated biomolecular condensates are implicated in a myriad of biological processes. Here the authors apply optical tweezers to characterize the viscoelasticity and interfacial tension of a range of condensates, finding that condensates can deviate from simple fluids in opposite directions; and identi
