Our understanding of progress in machine learning has been colored by flawed testing data.

“Blinking” behavior of fluorophores, being harmful for the majority of super-resolved techniques, turns into a key property for stochastic optical fluctuation imaging and its modifications, allowing one to look at the fluorophores already used in conventional microscopy, such as graphene quantum dots, from a completely new perspective. Here we discuss fluorescence of aggregated ensembles of graphene quantum dots structured at submicron scale. We study temperature dependence and stochastic character of emission. We show that considered quantum dots ensembles demonstrate rather complicated temperature-dependent intermittent emission, that is, “blinking” with a tendency to shorten “blinking” times with the increase of temperature.

Summary: Administering oxytocin to influential members of a social network helped increase overall group cooperation.

Administering oxytocin to the central members of a social network spreads cooperation via increased punishment of uncooperative behavior, according to new research published in Journal of Neuroscience.

Operators of the ALICE detector have observed the first direct evidence of the “dead cone effect,” allowing them to assess the mass of the elusive charm quark.

The ALICE collaboration at the Large Hadron Collider (LHC) in Geneva, Switzerland, recently made the first observation of an important aspect of particle physics called the “dead cone effect.”

The effect is a fundamental element of the strong nuclear force — one of the four fundamental forces of nature — responsible for binding quarks and gluons. These are the fundamental particles that comprise hadrons, such as protons and neutrons, that in turn make up all atomic nuclei, which are never seen on their own under normal circumstances, only at the kind of high energy levels generated at the LHC.

Scientists believe it likely that the two genes, PEN1 and SYP122, paved the way for all terrestrial plant life.

Researchers from the University of Copenhagen have shed new light on how plant life got established on the surface of our planet. They specifically demonstrated that two genes are crucial for terrestrial plants to protect themselves against fungal attack – a defense mechanism that dates back 470 million years. These defenses most likely paved the way for all terrestrial plant life.

Toronto-based start-up’s programmable photonic device is accessible to the public and much faster than classical machines at Gaussian boson sampling.

A new, multi-node FLEET review, published in Matter, investigates the search for Majorana fermions in iron-based superconductors.

“So fascinating and yet scary how unfathomably vast space is,” comments a user.

A marvelous animation takes those who view it on an illuminating adventure through outer space, beyond the Milky Way and ultimately to the edge of the known universe. Included in the journey are stunning revelations about the difficult-to-comprehend nature of distances measured in light years.

New research suggests that Darwinian evolution could be happening up to four times faster than previously thought, based on an analysis of genetic variation.

The more genetic differences there are in a species, the faster evolution can happen, as certain traits die off and stronger ones get established. The team behind this latest study calls it the “fuel of evolution”, and they looked at data on 19 different wild animal groups around the world.

That data analysis revealed this raw material for evolution is more abundant than earlier estimates, and as a result we may have to adjust our expectations for how quickly animals evolve – a pertinent question in our age of climate change.
