Copernicus! Tony Soprano! The inventor of the semicolon! The heroic obsessions of artist Isabel Nolan
Ireland’s artist at the Venice Biennale steals religious imagery for her secular celebrations of scientists and humanists, including an Italian punctuation master – and even TV’s famous mobsterIt’s a long way to the Irish pavilion at the Venice Biennale.
NASA will chase the Aug. 12 total solar eclipse with balloons and a high-altitude jet
"Scientists can study the sun's corona in a way we can't from anywhere else in the solar system." O recorte ajuda a contextualizar a pauta dentro de Lifestyle.
1-billion-year-old Mars meteorite found in Algeria is like nothing we've seen from the Red Planet
Scientists found a Martian meteorite on Earth that is finally filling in a nearly 2-billion-year-old geology-history gap on the Red Planet. Destaque: 600 mi, 2.4 bi, 1.3 bi.
Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, without changing the genetic sequence itself. A recent st
New math model sheds light on multiple sclerosis relapse and recovery cycles
A new mathematical model that reproduces the relapsing-remitting pattern of multiple sclerosis (MS) offers scientists a tool to better understand how the disease progresses.
New species discovered on Costa Rica's deep-sea seamounts
Scientists exploring seamounts off the coast of Costa Rica have discovered a new coral so genetically and morphologically distinct that it required the creation of an entirely new family for its classification.
MBNL1 identified as a potential cancer drug target for a type of childhood leukemia
Scientists from St. Jude Children's Research Hospital and collaborators have discovered that the RNA-binding protein MBNL1 promotes the growth of a form of childhood leukemia characterized by KMT2A gene rearrangements. The finding identifies MBNL1 as a promising therapeutic targe
People carrying a rare gene variant have naturally low body fat, healthier livers and bett
There are people around us who can maintain their weight despite what they eat. This has led scientists to believe that a person's metabolism and tendency toward obesity may have genetic factors behind them. A large study sequencing the genomes of more than 1 million people acros
AI framework decodes how brain regions talk to one another
For decades, neuroscientists have been able to record which parts of the brain show increased electrical activity during a behavior, such as when we form a memory or make a decision. But scientists haven't been able to determine how those regions are communicating with and influe
Lonely people can feel their heartbeat clearly like everyone else, but their brains respon
For a long time, psychologists have described loneliness as the discomfort that comes from wanting more social connection than we feel we have, but there is more nuance to loneliness. Scientists are increasingly finding that loneliness is also linked to how we respond to negative
Unexpected brain mechanism challenges assumptions about GLP-1s
For decades, obesity medications produced only modest weight loss. But in recent years, Ozempic and related GLP-1 therapies have transformed the field, enabling sustained weight loss of 10% to 15% or more. Despite their success, however, scientists have not fully understood how t
