Mario Krenn, a quantum physicist, recalls sitting at a Vienna café in early 2016 reading through computer printouts, trying to make sense of what MELVIN had discovered. MELVIN was a sort of artificial intelligence created by Krenn using a machine-learning algorithm. Its mission was to mix and match the components of typical quantum experiments to…

Last week, Republican Representative Louie Gohmert of Texas asked a US Forest Service employee if her agency or the Bureau of Land Management could alter the moon’s or Earth’s orbit to reverse the impacts of human-caused climate change during a congressional hearing. Doesn’t that seem like an entirely appropriate plan? Let’s get started. First, we…

This year, delta-8 THC, a new marijuana cousin, erupted onto the national scene. It’s advertised as “weed light” or “the superior version of THC” on the cannabis internet. It sold as a vape or an edible, and the high is similar to a moderate form of traditional marijuana. In terms of chemical structure—three carbon rings,…

Carl Georg Count Sievers, an amateur archaeologist, performed excavations along the Salaca River in Latvia in 1875. He discovered two graves: one for a 12-to-18-year-old girl (named RV 1852) and another for a 20-to-30-year-old man (designated RV 1853). (RV 2039). Analysis of RV 2039 about 150 years later reveals that not only is he over…

A nearly intact ancient human skull rested at the bottom of a well in Harbin City, Heilongjiang Province, China, for more than 80 years, according to Chris Stringer. According to legend, laborers building a bridge in Japanese-occupied northeastern China uncovered the specimen from the Songhua River’s bed in 1933. The crew foreman understood the worth…

A Soviet-era dam is providing energy for a distant mining operation somewhere in Siberia. However, nothing tangible is emerging from the soil. Instead, the hydroelectric power plant powers enormous machines that churn out complex mathematical answers. To put it another way, this renewable energy is being utilized to mine bitcoin. Jason Deane, a Bitcoin analyst,…

While apps like Signal make it possible to exchange encrypted communications, no system is fully secure. But, owing to quantum mechanics, the esoteric area of science that regulates the cosmos at the lowest scales, encryption may become far more difficult to crack in the future. You’re almost probably viewing this on an electrical gadget that…

A Canadian radio telescope discovered 535 fast radio bursts in one go, quadrupling the known number of these brief, very powerful events. The long-awaited findings reveal that these perplexing events may be divided into two types: one-time bursts and recurrent bursts that continue at least ten times longer on average. Fast radio bursts could be…

A tiny phase II clinical trial published on June 9 in the journal Science Translational Medicine indicated that nitrous oxide (often known as “laughing gas” in the dentist’s office) may help some people with treatment-resistant depression reduce their symptoms. Researchers have been interested in approaches that act faster than traditional depression medications, such as SSRIs,…

Techniques for inducing mutations in viruses that give microorganisms new abilities are included in the microbiology toolbox. Scientists do these experiments for a variety of purposes, including to learn how bacteria avoid detection by our immune systems. However, enhancing a pathogen’s capabilities comes with apparent hazards, especially if this “gain of function” implies increased virulence…

Here’s a game for you. In 1948, Claude Shannon, the father of information theory, devised. He was attempting to model English as a random process. Pick out a random book from your shelf, open it, point to a random area on the page, and write down the first two letters you see. Let’s pretend they’re…

A journey that began over a century ago with the invention of the first electron microscope has progressed once again.A group of physicists has gotten even closer to the ultimate limit of how many objects can be amplified, according to experts. The world record for the greatest resolution attained using a microscope was previously held…

The Coxcatlan Cave in Mexico’s Valley of Tehuacan has housed tens of thousands of years of human history through the millennia. Records of the early domestication of maize and the start of agriculture have been preserved in layers of dust, rocks, charcoal, and decaying plants. But under them, all lies something even more surprising: what…

COVID-19 aggravated several pre-existing racial health inequities, ushering in a racial reckoning in medicine. As a response, several medical institutions have endeavoured to make significant adjustments in their teaching and clinical environments to address systematic racism. The history of present illness (H.P.I.), a tool utilized by practically every physician daily, may, nevertheless, continue to perpetuate…

The current coronavirus pandemic may not appear to be an apparent catalyst for contemplating biological transcendence. But the weird thing is that we’ve been inadvertent participants in exactly such an event in our response to this crisis. The concept of transcendence has existed for a long time, under several names and guises. It captures the…

I’ve been invited to speak with well-known writers, singers, and film producers about my new book, Extraterrestrial, during the last several months. Before our chats, I had been the recipient (and admirer) of their creative work, but suddenly they were interested in my scientific studies. These discussions prompted me to see parallels between art and…

Scientists have been perplexed by a subatomic riddle for more than 40 years: why can pieces of splitting atomic nuclei emerge turning from the wreckage? According to experts, these baffling gyrations may now be explained by an action similar to that which occurs when a rubber band is snapped.Consider a big stack of coins to…

According to scientists, quasicrystals—so-called “impossible” materials with strange, non-repeating structures—have been discovered in leftovers of the world’s first nuclear bomb test. The hitherto unknown structure, composed of iron, silicon, copper, and calcium, was most likely created by using vaporized desert sand and copper wires. Similar materials have been made in the lab and found in…

The discovery that truth is essentially a permanent phenomenon is one of quantum mechanics’ most annoying consequences. Quantum mechanics is not just a microscopic theory: all matter is essentially quantum—just it’s that strange quantum phenomenon is difficult to find in something more significant than a few atoms. The life of macroscopic, so-called “classical” objects is…

It’s springtime, and the city is magnificent; this year’s snow looked like it was on top of winter. However, as we consider what gave us joy during this challenging period, birds were at the top of many people’s happy lists. Those we saw from our windows—or on the street in New York City—in particular. House…

Ultrahigh-energy cosmic rays have captivated scientists since their observation in the 1960s, who are curious about where they originate from. Like all cosmic rays, they are arguably misnamed: they are subatomic particles zipping through space, not “rays” of radiation. These ultrahigh energies are the product of ultrafast speeds that exceed the speed of light. A…

Physicists have been unable to solve the puzzle of what happened when a vanishingly tiny seed exploded into the cosmos for a long time. Now, one physicist believes he understands why scientists haven’t been able to come up with a physical explanation for inflation: the world won’t let us. The physicist explains a recent theory…

In 1833, a nearly perfectly spherical fish showed up on the shores of Greenland and was brought to Copenhagen, Denmark, by zoologist Johannes Christopher Hagemann Reinhardt. According to Ted Pietsch, a systematist and evolutionary biologist, this species — later identified as the footballfish, Himantolophus groenlandicus, or the man-gobbler — was the first anglerfish found in…

Since we perceive and sense things as people, we realize we are alive. On the other hand, scientists and great philosophers are stumped into what consciousness is and from where it comes. “Consciousness — or, to put it another way, conscious perception — is clearly a part of reality,” said Johannes Kleiner, a mathematician and…

My students and collaborators are planning a scientific conference for my 60th birthday, which will take place in about a year. “I have learned even more from my professors, more from my friends, and also the most from my students,” Rabbi Hanina said. We were all once students. Many of us have cuts and bruises…

NASA’s Operation IceBridge keeps track of the world’s shifting glaciers and ice sheets, such as Alaska’s Sheridan Glacier, photographed during a flight in August 2018. Sheridan Glacier has a floating tongue that is quickly eroding (the glacier portion that extends beyond the shoreline and floats on the water). On August 18, 2019, Iceland arranged a…

Entropy is a measurable physical property that is most often associated with a state of chaos, randomness, or ambiguity. The word and definition used in a wide range of fields, from classical thermodynamics, were first known to statistical physics’ microscopic explanation of existence and knowledge theory’s principles. Chemistry and physics, biological systems and their relationships to…
