I have spent the past several years of my life desperately trying to warn humanity that the robots are coming to destroy us all, and everybody laughed at me. But this week—shortly after the T-1000 was seen smooching his miniature horse and donkey—a robot noodle chef has taken over soba-making duties at a Tokyo train station, so who’s laughing now? (The robots are laughing now.)
To understand the behavior of quantum particles, imagine a pinball game—but rather than one metal ball, there are billions or more, all ricocheting off each other and their surroundings.
Physicists have long tried to study this interactive system of strongly correlated particles, which could help illuminate elusive physics phenomena like high-temperature superconductivity and magnetism.
One classic method is to create a simplified model that can capture the essence of these particle interactions. In 1963, physicists Martin Gutzwiller, Junjiro Kanamori and John Hubbard—working separately—proposed what came to be called the Hubbard model, which describes the essential physics of many interacting quantum particles. The solution to the model, however, only exists in one dimension. For decades, physicists have tried to realize the Hubbard model in two or three dimensions by creating quantum simulators that can mimic it.
We already have medicines for treating cytokine storm syndrome, the immune response that’s killing many who die of Covid-19.
In 2018, Putin approved a national research strategy that stretches to 2024. It calls for more money, extra support for early-career scientists, and some 900 new laboratories, including at least 15 world-class research centres with a focus on mathematics, genomics, materials research and robotics. Last year, the government completed a sweeping evaluation of scientific performance at its universities and institutes; it has vowed to modernize equipment in the 300 institutes that made the top quartile. And it says it wants to strengthen previously neglected areas, including climate and environmental research (see ‘Russia’s climate-science ambitions’).
Some researchers see promise in planned reforms.

An advanced communications system comprising an emitter and an improved receiver (detector) utilizing modulated beams of neutrino and antineutrino waves as information carriers between the emitter and the receiver. of modulated neutrino and antineutrino beams in the emitter is achieved by a laser-like medium, while detection and demodulation of the neutrino and antineutrino beams is accomplished by a second laser-like medium which registers the flux (or of modulated neutrinos and antineutrinos passing there-through by means of resonant stimulated deexcitation of lasable excited states. In addition to the information transmission utilization, the neutrino emitter and receiver (detector) system may also be employed to gather information by the probing of internal earth structures. Such structures cause measurable refractions and retardations of the propagated pulses of monochromatic neutrino waves traveling through the earth between the emitter and receiver (detector), at certain predetermined neutrino

Recent NASA findings show there is a lot of water on Mars — but can future settlers actually drink it? If not, what will be needed for making water on Mars?

Radiocarbon dating, invented in the late 1940s and improved ever since to provide more precise measurements, is the standard method for determining the dates of artifacts in archaeology and other disciplines.
“If it’s organic and old—up to 50,000 years—you date it by radiocarbon,” said Sturt Manning, the Goldwin Smith Professor of Classical Archaeology in the College of Arts and Sciences.
A new paper led by Cornell University points out the need for an important new refinement to the technique. The outcomes of his study, published March 18 in Science Advances, have relevance for understanding key dates in Mediterranean history and prehistory, including the tomb of Tutankhamen and a controversial but important volcanic eruption on the Greek island of Santorini.
Could Mercury’s close orbit to the sun help the planet generate ice? This sounds like a paradox, but a new study shows how it could happen.
An ancient Elpistostege fish fossil found in Miguasha, Canada has revealed new insights into how the human hand evolved from fish fins.
An international team of palaeontologists from Flinders University in Australia and Universite du Quebec a Rimouski in Canada have revealed the fish specimen, as described in the journal Nature, has yielded the missing evolutionary link in the fish to tetrapod transition, as fish began to foray in habitats such as shallow water and land during the Late Devonian period millions of years ago.
This complete 1.57 metre long fish shows the complete arm (pectoral fin) skeleton for the first time in any elpistostegalian fish. Using high energy CT-scans, the skeleton of the pectoral fin revealed the presence of a humerus (arm), radius and ulna (forearm), rows of carpus (wrist) and phalanges organized in digits (fingers).
