UN ‘Pause’ campaign has helped slow spread of life-threatening misinformation

2021-07-06 10:33 The UN’s Pause campaign, which encourages social media and other news consumers to stop and check the validity of information they share, received a major endorsement on Thursday after a study from a leading research institute in the United States concluded that it has helped encourage the behavioural change needed to stop the spread of misinformation online. The report from the Massachusetts Institute of ...

And the monolayer is not the limit: physicists have discovered a new class of ultrathin magnets

2021-07-05 16:55 Electronic devices are getting smaller every year — the elements they consist of are also decreasing. Physicists from the Kurchatov Institute synthesized submonolayer magnetic films-ordered structures with a thickness of one atom, but significantly more sparse than a monolayer of matter. These objects represent a fundamentally new class of two-dimensional magnetic materials and can become the basis for crea...

New technology allows you to print words with the power of thought

2021-07-04 14:52 Scientists from the US state of California have created a technology that allows people to write text messages with the power of thought. They implanted several chips in a person's head that read the activity of his brain and convert it into handwritten text on the screen. It is believed that this technology will return the paralyzed people the opportunity to communicate with their relatives and the wor...

Embryos of many species use sound to prepare for the outside world

2021-07-04 12:47 It's well known that reptiles depend on temperature cues while in the egg to determine a hatchling's sex. Now, researchers writing in the journal Trends in Ecology & Evolution on May 26 say that embryos of many different animal species also rely on acoustic signals in important ways. They call this phenomenon "acoustic developmental programming." "Acoustic developmental programming occurs when a so...

New data has confirmed that the extinction of the dinosaurs began long before the asteroid hit

2021-07-03 16:31 Non-avian dinosaurs began to lose in the struggle for survival millions of years before the Cretaceous-Paleogene extinction, and the reason for this is the cooling and the appearance of more advanced competitors. All non-avian dinosaurs became extinct during the Cretaceous-Paleogene extinction event, about 66 million years ago. It is believed that it was launched by the fall of a massive celestial body tha...

Coincidence? I think so: researchers use phylogenetics to untangle convergent adaptation in birds

2021-06-24 19:18 Researchers from Skoltech and their colleagues have shown that adaptation to similar environments hardly involves similar genomic positions when species are distantly related. The team investigated recurrent adaptations of wildlife birds’ mitochondria to high altitude, migration, diving, wintering, and flight. Repeatable substitutions are rather a coincidence than adaptation, which confirms the scientific o...

Scientists have found out what makes a person sneeze

2021-06-20 12:40 American scientists have identified the neural mechanism of sneezing. It turned out that this process is responsible for areas of the brain that are not associated with breathing. Scientists first identified the area in the central nervous system that causes sneezing more than twenty years ago, but until now little was known about how the sneezing reflex works at the cellular and molecular level. Researche...

The toothy "hummingbird dinosaur" turned out to be an ancient lizard

2021-06-19 12:27 Paleontologists have put an end to the debate about a strange animal found in Cretaceous amber: it is not a primitive bird that still retained its teeth in its beak, but an ancient scaly lizard.Last year, Chinese paleontologists presented an amazing find — a fragment of ancient amber, which perfectly preserved the remains of one of the most miniature dinosaurs in history. The sample was dated to be about 99...

CERN scientists have discovered a new subatomic particle that can spontaneously transform into an antiparticle and back

2021-06-16 12:05 Antimatter, as far as we know, is a perfect "mirror image" of ordinary matter, the only real difference between these two antipodes is the opposite electric charges. And, when an antimatter particle comes into contact with a particle of ordinary matter, they both die, destroying each other in a burst of energy. Complicating the above, we can say that some particles, such as photons, are also their own antip...

190 years since the birth of James Maxwell

2021-06-13 13:02 James Clerk Maxwell FRSE FRS (13 June 1831 – 5 November 1879) was a Scottish scientist in the field of mathematical physics. His most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the...

Scientists discover new gene for circadian rhythms

2021-06-10 18:06 A team of biologists, physiologists, and neurologists has discovered an important regulatory DNA molecule that is responsible for the amplitude of circadian rhythms. So far, the study was conducted only on cultured mouse cells, but scientists are confident that a similar gene exists in humans. Circadian rhythms are 24-hour cycles that run in the background so that a person can perform basic functions. One ...

Mysterious Extinction Kills 70 Percent of Sharks on Earth

2021-06-09 11:10 Scientists have discovered a previously unknown shark mass extinction event that wiped out the global population of these marine predators about 19 million years ago. It is currently a mystery what happened to the shark population, but the authors of the study say that as a result of this event, sharks almost completely disappeared from the world's oceans. Sharks and their ancestors have been swimming ...
