105 Scientists finally reveal how this Alzheimer’s drug really works

ScienceDaily
ScienceDaily 1 place · today 07:44 EDT

A key Alzheimer’s drug has finally revealed its secret. Researchers discovered that lecanemab works by activating the brain’s immune cells—but only through a specific part of the antibody called the Fc fragment. This piece acts like a trigger, prompting microglia to clear harmful amyloid plaques. The finding could reshape how future Alzheimer’s therapies are designed.

От стратегии до проектов: для чего бизнесу переходить к портфельному управлению

Портфели проектов появляются в компании не потому, что это модный управленческий термин. Они возникают тогда, когда планов становится слишком много, а ресурсов и денег — слишком мало, чтобы ими разбрасываться. В 2026 году у крупных организаций одновременно реализуются десятки инициатив: цифровая трансформация, импортозамещение, развитие продуктов, модернизация инфраструктуры. В таких условиях инвестиционные портфели проектов становятся не формальностью, а инструментом выживания и роста.Если коротко: отдельн Read more

I realized I don’t procrastinate because I’m lazy. I procrastinate because finishing something means submitting it to judgment, and somewhere in my childhood the message landed that completed work is just an invitation for someone to tell you what’s wrong with it.

Procrastination often has nothing to do with laziness and everything to do with a deeply wired fear of judgment — a pattern frequently installed in childhood and reinforced by perfectionism. Understanding the real mechanics of avoidance is the first step toward finishing anything. Read more

Кибербудда и теория всего: как мы создаём вещи одним взглядом и почему искусственный интеллект будет страдать

Физики часто мечтают о создании "теории всего" - минимального набора математических уравнений, описывающих все возможные физические явления. Но реальный мир не сводится к одной только физике - эволюция клеток, средневековая история и устройство компьютеров нельзя свести к описанию поведения электронов. А следовательно настоящая "теория всего" должна описывать не только физику, но и всё остальное многообразие явлений с помощью единого набора абстракций и единого математического аппарата. В этом эссе я разбер Read more

Scientists at Oregon Health & Science University have developed a new molecule that could open the door to treating triple-negative breast cancer, one of the most aggressive and difficult-to-treat forms of the disease. The compound, called SU212, targets and disables a key enzyme that cancer cells rely on to fuel their growth. In tests using humanized mouse models, the molecule caused tumors to shrink and slowed the spread of cancer... Read more

Cancer often begins when the genetic instructions that guide our cells become scrambled, allowing cells to grow uncontrollably. Now, scientists at EMBL have developed an AI-powered system called MAGIC that can automatically spot and tag cells showing early signs of chromosomal trouble—tiny DNA-filled structures known as micronuclei that are linked to future cancer development.

Scientists at Oak Ridge National Laboratory have created a new aluminum alloy called RidgeAlloy that can turn contaminated car-body scrap into strong structural vehicle parts. Normally, impurities introduced during recycling make this scrap unsuitable for high-performance applications. RidgeAlloy overcomes that challenge, enabling recycled aluminum to meet the strength and durability standards required for modern vehicles. The technology could slash energy use, reduce imports, and unlock a huge new supply o Read more

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While studying the paths of light rays and moving objects, Hamilton noticed a striking mathematical similarity between them and used it to develop a powerful new framework for mechanics. At the time, it seemed like a clever analogy—but decades later, as... Read more

Using a synchrotron accelerator, X-ray imaging, robotics, and AI, the team scanned 2,000 specimens in just a week and produced models of 800 species. The images reveal microscopic anatomy that was previously difficult to study. The growing Antscan database could become a powerful digital library of biodiversity. Read more

THC doesn’t just blur memories—it can create new ones that never happened. In a controlled experiment, cannabis users were much more likely to recall words that were never shown and struggled with tasks like remembering to do something later. Researchers found that THC disrupted many different memory systems at once. Surprisingly, moderate doses caused memory problems similar to higher doses. Read more

A long-running debate about the Silverpit Crater beneath the North Sea has finally been resolved. Scientists now confirm it formed when a roughly 160-meter asteroid struck the seabed about 43–46 million years ago. New seismic imaging and rare shocked minerals in rock samples provided the crucial proof. The impact would have sent a massive plume skyward and unleashed a tsunami over 100 meters (330 feet) high.

As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, iron-limited conditions by using iron more efficiently. Because these microbes control key nitrogen reactions that support marine life, their adaptability could help sustain ocean productivity. In a warming world, they may play an even bigger role in shaping marine nutrient cycles. Read more

Researchers have uncovered a molecular trick used by hornwort plants that could help future crops capture carbon dioxide more efficiently. A unique protein feature called RbcS-STAR causes the key photosynthesis enzyme Rubisco to cluster into dense compartments, helping it work more effectively. When scientists added this feature to other plants, Rubisco reorganized in the same way. The finding raises the possibility of engineering more efficient photosynthesis into major crops. Read more
