How many new particles has the LHC discovered? The most widely known discovery is of course that of the Higgs boson. Less well known is the fact that, over the past 10 years, the LHC experiments have also found more than 50 new particles called hadrons. Coincidentally, the number 50 appears in the context of hadrons twice, as 2021 marks the…

Mars rovers safe from lightning strikes, research finds
If experiments done in small bottles in a University of Oregon lab are accurate, the friction of colliding Martian dust particles are unlikely to generate big electrical storms or threaten the newly arrived exploration vehicles or, eventually, human visitors.

Research Linking Violent Entertainment To Aggression Retracted After Scrutiny
Science magazine: As Samuel West combed through a paper that found a link between watching cartoon violence and aggression in children, he noticed something odd about the study participants. There were more than 3000 — an unusually large number — and they were all 10 years old. “It was just too perfect,” says West, a Ph.D. student in social psychology at…
Lucid dreamers can hear and answer questions while still asleep, scientists find
Researchers have successfully achieved real-time communication with a sleeping person by invading their dreams in several independent experiments. Source: https://www.livescience.com/real-time-communication-while-dreaming.html
Dark streaks on Mars may be caused by salts and melting ice
Researchers at the SETI Institute say that unusual dark streaks on sun-facing slopes on Mars, debated about for years, may be small landslides caused by a combination of salts and melting ice just below the surface.

Random twists of place: How quiet is quantum space-time at the Planck scale?
Fermilab scientists have been conducting experiments to look for quantum fluctuations of space and time at the smallest scale imaginable according to known physics. At this limit, the Planck length, our classical notions of space and time break down. …
How Our Brutal Science System Almost Cost Us a Pioneer of mRNA Vaccines
Long-time Slashdot reader theodp writes: As the first COVID-19 vaccines arrived at Penn Medicine last year, Penn Today reported with great pride, “It was mRNA research conducted at Penn—by Drew Weissman, a professor of Infectious Diseases, and Katalin Karikó, an adjunct associate professor—that helped pave the way for the development of the Pfizer-BioNTech and Moderna COVID vaccines.” While Weissman and Karikó…
Microsoft’s Big Win in Quantum Computing Was an ‘Error’ After All
In a 2018 paper, researchers said they found evidence of an elusive theorized particle. A closer look now suggests otherwise. From a report: In March 2018, Dutch physicist and Microsoft employee Leo Kouwenhoven published headline-grabbing new evidence that he had observed an elusive particle called a Majorana fermion. Microsoft hoped to harness Majorana particles to build a quantum computer, which promises…
Applying quantum computing to a particle process
A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that occur at CERN’s Large Hadron Collider. …
