Key brain region was “recycled” as humans developed the ability to read

Key brain region was “recycled” as humans developed the ability to read

Sarah McDonnellEmail: Phone: 617-253-8923MIT News Office1 images for downloadMedia can only be downloaded from the desktop version of this website.Humans began to develop systems of reading and writing only within the past few thousand years. Our reading abilities set us apart from other animal species, but a few thousand years is much too short a timeframe for our brains to have evolved new areas specifically devoted to reading.To account for the development of this skill, some scientists have hypothesized that parts of the brain that originally evolved for other purposes have been...

Longitudinal study explores the interplay between fear-enhancing parenting and children’s cognitive biases and anxiety

Longitudinal study explores the interplay between fear-enhancing parenting and children’s cognitive biases and anxiety

Research published in suggests that children’s cognitive biases and anxiety symptoms encourage fear-enhancing behavior in parents, and not the other way around.Anxiety in youth is alarmingly common, sparking much research into its etiology. One prominent theory suggests that cognitive biases during information processing can help maintain anxiety in children. One such bias is confirmation bias, which refers to the tendency to look for information that confirms one’s viewpoint while ignoring alternate information.  Another is interpretation bias, which refers to the tendency to interpret...

Alcoholism treatment is potentially effective against COVID-19

Alcoholism treatment is potentially effective against COVID-19

A team of chemists from HSE University and the Zelinsky Institute of Organic Chemistry used molecular modelling to find out that two medications that have been known for a long time can be used to fight SARS-CoV-2. These are disulfiram, which is used to treat alcoholism, and neratinib, an experimental drug being used to treat breast cancer. The paper about the discovery has been available online since August 4, 2020, in the 4th issue of Mendeleev Communications journal.The structural elements of the virus that are less subject to mutation during its evolution should be chosen as a target...

Neuroimaging study suggests a single dose of ayahuasca produces lasting changes in two important brain networks

Neuroimaging study suggests a single dose of ayahuasca produces lasting changes in two important brain networks

Consuming a single dose of the psychedelic brew ayahuasca can result in lasting changes in higher-order cognitive brain networks, according to a new study published in the .Ayahuasca, a concoction used for centuries by indigenous Amazon tribes, contains the powerful psychedelic drug dimethyltryptamine (DMT) and monoamine oxidase inhibitors. The brew is typically prepared using leaves from the Psychotria viridis shrub and the bark of the Banisteriopsis caapi vine.The new neuroimaging research suggests that ayahuasca may produce long-lasting effects on mood by altering the functional...

Supporters of religious violence are more likely to claim they're familiar with religious concepts that don't exist

Individuals who claim knowledge of fake religious concepts are more supportive of religious aggression, while individuals with accurate religious knowledge are less supportive, according to new research published in .“Although many quote the Christian Bible, few have read it. Thus, religious books are often incorrectly cited or cited in a way that serves personal prejudices and/or distorted worldviews,” said study author , an assistant professor at the University of Nevada Reno.“Not only do people ‘pick and choose’ the stories of a religious book to support their worldview, they...

How to deal with spinors in SUSY. a.k.a. what is the van der Waerden… | by Pretty Much Physics | Aug, 2020 | Medium

a.k.a. what is the van der Waerden notation?Quantum field theory is hard, there’s no way to deny that. Especially when supersymmetry (SUSY) enters the game. In this article, we will go over the basic starting points on how to deal with spinors, as they usually appear in supersymmetric theories. In particular, there are three (yes, three) ways to denote the same expression when it involves spinors: index notation, compact index notation, and matrix notation. We will explore how they are related and how to switch between them.These notes are something I would have loved to read when I started...

SpaceX caps busy week with launch of 57 more Starlink satellites

A SpaceX Falcon 9 rocket vaulted back into space early Friday, boosting another 57 Starlink internet relay stations into orbit along with two BlackSky remote sensing microsatellites. The launching of the first stage booster marked its fifth flight.It capped a busy week for the California rocket builder beginning with the successful splashdown of a Crew Dragon capsule Sunday that brought two NASA astronauts back to Earth from the International Space Station. The flight was the first to orbit for NASA astronauts from U.S. soil since the space shuttle was retired in 2011.Two days after...

The results are being used to illuminate complex circulation patterns in the Martian atmosphere.The MAVEN team was surprised to find that the pulsed exactly three times per night, and only during Mars' spring and fall.

Wayward Satellites Test Einstein’s Theory of General Relativity

Wayward Satellites Test Einstein’s Theory of General Relativity

In August 2014 a rocket launched the fifth and sixth satellites of the Galileo global navigation system, the European Union's $11-billion answer to the U.S.'s GPS. But celebration turned to disappointment when it became clear that the satellites had been dropped off at the wrong cosmic “bus stops.” Instead of being placed in circular orbits at stable altitudes, they were stranded in elliptical orbits useless for navigation.The mishap, however, offered a rare opportunity for a fundamental physics experiment. Two independent research teams—one led by Pacôme Delva of the Paris Observatory in...

The Feds Want These Teams to Hack a Satellite—From Home

Alvaro Prieto kept “astronaut” open as a career option. When his family moved from Mexico to Florida—the state where the actual astronauts lift off—his off-world fascination only grew. “After surviving one year in the US, my gift was ,” he says, referring to the famous kids’ program in Huntsville, Alabama. Later, he convinced his dad to drive up to Cape Canaveral to watch the shuttle Discovery’s final ride, soon bidding farewell to the era of spaceflight he’d grown up with.So, yeah, Prieto likes space. But, no, he didn’t become an astronaut: Instead, he’s an electrical and firmware engineer...

Fossil captures ancient ‘hell ant’ in action

Fossil captures ancient ‘hell ant’ in action

A new fossil reveals how a mysterious ancient insect captured its meals.The discovery depicts a 99-million-year-old encounter between a “hell ant,” one of the earliest known ants, and its prey, an extinct relative of the cockroach. Preserved in amber, the ant, less than half the length of a dime, grasps the victim’s neck between two sharp mandibles and a hornlike protrusion on its head (pictured left, illustrated right).The find highlights hell ants’ strange anatomy. Whereas the mandibles of modern ants (as well as all adult insects) move horizontally, those of hell ants moved vertically,...
