Scientists finally reveal how this Alzheimer’s drug really works

Lecanemab, marketed as Leqembi, is a monoclonal antibody treatment for Alzheimer’s disease that targets and removes harmful amyloid plaques while slowing cognitive decline. Scientists from VIB and KU Leuven have now uncovered exactly how it works. Their research shows that a specific part of the antibody, known as the ‘Fc…

This massive crater could expose the heart of a lost planet

More than two centuries after asteroid 16 Psyche was first identified, scientists are still trying to determine how it formed. Located in the main asteroid belt between Mars and Jupiter, Psyche ranks as the 10th-most massive asteroid and the largest known object made primarily of metal, measuring about 140 miles…

Certificati anti-Cpr, la gip: ‘Gravi condotte antigiuridiche’ – Notizie – Ansa.it

I falsi certificati anti-rimpatrio sono stati realizzati per evitare il trasferimento degli stranieri irregolari nei Cpr, in un’ottica “di aperta contestazione del sistema di gestione dell’immigrazione clandestina”. Il dato è emerso, secondo il Gip Federica Lipovscek, dall’indagine della Procura di Ravenna a carico di otto medici del reparto di Malattie…

ADHD brains show sleep-like activity even while awake

A new study published in JNeurosci explores how brief bursts of sleep like brain activity during wakefulness affect a person’s ability to stay focused. Elaine Pinggal of Monash University and her team investigated whether this type of brain activity plays a role in attention challenges, particularly in adults with ADHD.…

NASA’s Webb captures a bizarre brain-shaped nebula around a dying star

New images from NASA’s James Webb Space Telescope are providing a clearer look at a mysterious and rarely studied nebula surrounding a dying star. The observations reveal new details about the structure of this unusual cloud of gas and dust and how it is changing over time. Called Nebula PMR…

DNA origami vaccines could be the next leap beyond mRNA

The COVID-19 pandemic brought messenger RNA (mRNA) vaccines into the global spotlight. After completing clinical trials, the first COVID-19 mRNA vaccine was given on December 8, 2020. Researchers later estimated through modeling that these vaccines prevented at least 14.4 million deaths worldwide during their first year. Because of their strong…

Rare supernova from 10 billion years ago may reveal the secret of dark energy

Astronomers may be getting closer to understanding one of the biggest mysteries in cosmology: dark energy, the unknown force believed to be driving the accelerating expansion of the universe. Dark energy is thought to account for about 68% of the universe. Despite its enormous influence, scientists still do not know…

A strange twist in the universe’s oldest light may be bigger than we thought

Researchers investigating a mysterious cosmic phenomenon called cosmic birefringence have created a new approach to reduce uncertainty in how it is measured. The advance, reported in Physical Review Letters, could improve the precision of observations that probe fundamental physics. The study is the first to quantitatively examine uncertainty in the…

Scientists inject one tumor and watch cancer vanish across the body

For more than two decades, scientists have explored a group of cancer drugs known as CD40 agonist antibodies. Early experiments suggested these treatments could strongly activate the immune system and help it destroy cancer cells. However, results in people were disappointing. Clinical trials showed only modest benefits, and the drugs…
