Meet Chesley Bonestell, The Most Important Space Artist You’ve Probably Never Heard Of

Over the last half century, spacecraft have visited every planet and their major moons, as well as two dwarf planets and more than a dozen asteroids and comets. Thanks to high-res images, we know these worlds intimately and can appreciate what makes each of them unique. These days, fewer than 3 in 10 Americans are old enough to recall a time when our neighboring worlds were indistinct dots in even

Washington, D.C., Enacts a Phaseout of Gas-Powered Leaf Blowers

Are Atheists Genetically Damaged?

I just came across a paper with an interesting title: The Mutant Says in His Heart, “There Is No God”. The conclusions of this work are even more interesting.

Studies show that these social cash transfer programs create income and welfare benefits for poor households and the local economies where they live. However, this may come at the cost of damaging local…

Networks of electrostatic and hydrophobic interactions modulate the complex folding free energy surface of a designed {beta}{alpha} protein [Biophysics and Computational Biology]

The successful de novo design of proteins can provide insights into the physical chemical basis of stability, the role of evolution in constraining amino acid sequences, and the production of customizable platforms for engineering applications. Previous guanidine hydrochloride (GdnHCl; an ionic denaturant) experiments of a designed, naturally occurring βα fold,…

Working memory capacity is enhanced by distributed prefrontal activation and invariant temporal dynamics [Neuroscience]

The amount of information that can be stored in working memory is limited but may be improved with practice. The basis of improved efficiency at the level of neural activity is unknown. To investigate this question, we trained monkeys to perform a working memory task that required memory for multiple…

Changes in belowground biodiversity during ecosystem development [Ecology]

Belowground organisms play critical roles in maintaining multiple ecosystem processes, including plant productivity, decomposition, and nutrient cycling. Despite their importance, however, we have a limited understanding of how and why belowground biodiversity (bacteria, fungi, protists, and invertebrates) may change as soils develop over centuries to millennia (pedogenesis). Moreover, it is…

Optogenetic reactivation of memory ensembles in the retrosplenial cortex induces systems consolidation [Neuroscience]

The neural circuits underlying memory change over prolonged periods after learning, in a process known as systems consolidation. Postlearning spontaneous reactivation of memory-related neural ensembles is thought to mediate this process, although a causal link has not been established. Here we test this hypothesis in mice by using optogenetics to…

Elevated signature of a gene module coexpressed with CDC20 marks genomic instability in glioma [Medical Sciences]

Genomic instability (GI) drives tumor heterogeneity and promotes tumor progression and therapy resistance. However, causative factors underlying GI and means for clinical detection of GI in glioma are inadequately identified. We describe here that elevated expression of a gene module coexpressed with CDC20 (CDC20-M), the activator of the anaphase-promoting complex…

Graphene transistor based on tunable Dirac fermion optics [Applied Physical Sciences]

We present a quantum switch based on analogous Dirac fermion optics (DFO), in which the angle dependence of Klein tunneling is explicitly utilized to build tunable collimators and reflectors for the quantum wave function of Dirac fermions. We employ a dual-source design with a single flat reflector, which minimizes diffusive…

Higher offspring mortality with short interbirth intervals in free-ranging rhesus macaques [Anthropology]

Short birth intervals have long been linked to adverse child outcomes in humans. However, it remains unclear the extent to which the birth interval has a direct influence on offspring mortality, independent of the confounding effects of modern environments and human sociocultural practices on reproductive behavior. Outside of humans, the…

Revealing the mechanism of how cardiac myosin-binding protein C N-terminal fragments sensitize thin filaments for myosin binding [Biophysics and Computational Biology]

Cardiac muscle contraction is triggered by calcium binding to troponin. The consequent movement of tropomyosin permits myosin binding to actin, generating force. Cardiac myosin-binding protein C (cMyBP-C) plays a modulatory role in this activation process. One potential mechanism for the N-terminal domains of cMyBP-C to achieve this is by binding…

Generalized network dismantling [Applied Mathematics]

Finding an optimal subset of nodes in a network that is able to efficiently disrupt the functioning of a corrupt or criminal organization or contain an epidemic or the spread of misinformation is a highly relevant problem of network science.

Structural and mechanistic insights into mechanoactivation of focal adhesion kinase [Biochemistry]

Focal adhesion kinase (FAK) is a key signaling molecule regulating cell adhesion, migration, and survival. FAK localizes into focal adhesion complexes formed at the cytoplasmic side of cell attachment to the ECM and is activated after force generation via actomyosin fibers attached to this complex. The mechanism of translating mechanical…

Deprivation of glutamine in cell culture reveals its potential for treating cancer [Medical Sciences]

The growth-stimulating capacity of calf serum (CS) in cell culture reaches a maximum of 10% with Balb 3T3 cells, remains at a plateau to 40% CS, and declines steeply to 100% CS. Growth capacity can be largely restored to the latter by a combination of cystine and glutamine. Glutamine is…

Glucocorticoid enhancement of recognition memory via basolateral amygdala-driven facilitation of prelimbic cortex interactions [Neuroscience]

Extensive evidence indicates that the basolateral amygdala (BLA) interacts with other brain regions in mediating stress hormone and emotional arousal effects on memory consolidation. Brain activation studies have shown that arousing conditions lead to the activation of large-scale neural networks and several functional connections between brain regions beyond the BLA….

With the Mars InSight Lander Stuck, NASA Tries to Hack a Fix With Earthly Clones

Last month, NASA's Mars InSight lander started digging into the Red Planet. Its HP3 (Heat Flow and Physical Properties Package) instrument was designed to burrow and measure Mars from underground, uncovering new geological evidence about how heat flows through the Martian soil. The part of this instrument that actually burrows into the ground is known as the mole. It was meant to penetrate up to 1

Strength training may reduce the risk of diabetes in obesity

Strength training over a short time period can reduce fat stores in the liver and improve blood glucose control in obese mice, according to a study published in the Journal of Endocrinology. The study reports that strength training over a short time-period, less than would be enough to change body fat composition in humans, was sufficient to reduce the accumulation of liver fat and improve regulat

The Atlantic Daily: ‘Darkest Days’

What We’re Following At least 49 people were killed in mass shootings during Friday Prayer at two mosques in Christchurch.

The gruesomeness of the attack was only heightened through online materials left by a suspect, a white Australian man now in pol

The problem isn’t capitalism, it’s the culture of infinite growth.

Growth means that you always need to make more money, so companies increase prices for a while but then under consumer pressure they always end up producing more stuff to sell. Producing more and more and more stuff only creates more and more and more waste, and leads to more and more pollution and destruction of ecosystems. Capitalism is not the main problem, the culture of growth is. You can ha

The researchers say that this means cancer teams may need to consider testing for personality types to try

While turning 100 can get you a shout out on the Today show, there’s nothing newsworthy about surviving into your 70s. That’s just expected based on life expectancy.
