Neutrinos created by LHC went undetected earlier, but FASER changed that and can help us learn more about deep space.
Researchers at the European Organization for Nuclear Research, commonly known as CERN, have detected neutrinos created by the Large Hadron Collider (LHC) experiment for the very first time. These were the highest energy neutrinos that were ever produced in a laboratory setup and are similar to those found in particle showers from deep space.
First detected in 1956, neutrinos are subatomic particles that play a key role in the burning of stars. Every time nuclei of atoms either come together (fusion) or break apart (fission) in the universe, neutrinos are released.

One of the most abundant particles of the cosmos, neutrinos play an important role in the standard model of particle physics too. Researchers have been creating neutrinos in the lab to study but never have they been detected by the giant laboratory of the LHC.
The powerful psychedelic can give you a near-death experience. Here is how it affects your brain on the inside.
Dimethyltryptamine, or DMT, is a powerful psychedelic whose effect on the human brain lasts for only some minutes, but in that short span of time, the user experiences some high-level mental changes.
The researchers examined the brain activity of the participants before, during, and after the DMT test. Here is what they found.

For the first time, a team of researchers from the Imperial College of London has monitored these changes in detail. They administered a high dose of DMT to 20 healthy individuals who voluntarily participated in their study.
Dark matter does not emit or reflect light, nor does it interact with electromagnetic forces, making it exceptionally difficult to detect. Nevertheless, a research team from The Education University of Hong Kong (EdUHK) has proven that there is a substantial amount of dark matter surrounding black holes. The study results are published in the journal The Astrophysical Journal Letters.
The team selected two nearby black holes (A0620-00 and XTE J1118+480) as research subjects, with both considered as binary systems. That is, each of the black holes has a companion star orbiting it. Based on the orbits of the companion stars, observations indicate that their rates of orbital decay are approximately one millisecond (1ms) per year, which is about 50 times greater than the theoretical estimation of about 0.02ms annually.
To examine whether dark matter exists around black holes, the EdUHK team applied the “dark matter dynamical friction model”—a theory widely held in academia—to the two chosen binary systems, through computer simulations. The team found that the fast orbital decay of the companion stars precisely matches the data observed.
Speeding through the Universe and leaving a wake of new stars, this runaway supermassive black hole is likely the first among thousands.
Using AI, Ting Xu and her colleagues designed polymer mixtures that mimic the natural proteins in biological fluids. The technique could improve the design of biocompatible materials.

Daniel Dennett.
May 14, 2014
Serious thinkers contend that free will cannot exist in a deterministic universe — one in which events are the singular outcomes of the conditions in which they occur. The alternative view, that free will is prerequisite for personal responsibility and morality, is the basis of our legal and religious institutions. Philosopher Daniel Dennett unravels this conundrum and asks whether we must jettison one of these notions, or whether they can co-exist. He then asks: if free will is an illusion, as many scientists say, should we conclude that we don’t need real free will to be responsible for our actions?
Daniel Dennett is the Austin B. Fletcher Professor of Philosophy and Director, Center for Cognitive Studies at Tufts University.

Today we’re going to try to save reality — or at least realism. However this rescue effort has a price; one that you may not be willing to pay. Your very soul, or at least your free will, is on the line.
