923 Monster black holes are silencing star formation across the universe

ScienceDaily
ScienceDaily · 03/30/2026 08:23 EDT

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear faint or missing. The finding suggests galaxies grow and evolve together, not in isolation.

Psychology says the cruelest thing about being raised by a narcissistic but charming parent isn’t anything they did at home — it’s the structural impossibility of being believed by anyone outside the house, and a child who learns early that the world will never see what they see grows into an adult who has stopped trying to be understood by people who weren’t there

Most discussions of narcissistic parenting focus on what happens inside the house. The criticism. The control. The manipulation. The endless requirement that the child organize themselves around the parent’s emotional needs. These are all real, well-documented, and worth talking about. But there is a second feature of being raised by this kind of parent that ... Read more Read more

Геноцид «технарей»

Куда податься если 6 стало 9? "Чёрный слон" уничтожит многих, кто любит свою профессию, кто вникал ещё с детских кружков по информатике. И уничтожит не от того, что, как многие говорят "ИИ делает работу лучше", а просто из-за того, что мнение "массы" взяло верх, и нормальному человеку с этой глупостью невозможно смириться. Планомерное ли это уничтожение или ошибка в управлении, я не знаю. Может быть это первый акт мелодраммы о... Read more

[Перевод] Электронные лампы — удивительные долгожители

В течение последних десятилетий технический прогресс по большей части заключался в нахождении новых сфер применения полупроводников и разработке методов для их производства. Микросхемы теперь есть почти в любом автомобиле, воздушном судне или бытовом приборе. Светодиоды уверенно заменяют более старые и менее эффективные способы генерации света (вроде ламп накаливания). Солнечные панели стали самым быстро развёртываемым источником энергии в истории. Разработка полупроводниковых лазеров дала нам оптико-волоко Read more

A new analysis of the “Boltzmann brain” paradox suggests our memories and sense of reality could, in theory, be random illusions born from cosmic chaos. By uncovering circular reasoning in how physicists think about time and entropy, the study raises fresh doubts about what we can truly know about the past. Read more

The brain’s memory center may begin life more like a crowded web than an empty canvas. Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time. This pruning process creates a faster, more efficient system for linking experiences and forming memories. It challenges the idea that the brain starts from scratch. Read more

Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality. New research suggests that spontaneous “collapse” processes—possibly linked to gravity—could subtly blur time itself. This wouldn’t affect clocks we use today, but it reveals a hidden limit to how precise time can ever be. The findings open a new path toward uniting quantum physics with gravity. Read more

A hidden force may be quietly shaping how you feel—and you’d never even know it. Infrasound, an ultra-low-frequency vibration below the range of human hearing, is everywhere from traffic to old buildings. In a small experiment, people exposed to it became more irritable, less engaged, and even showed higher levels of the stress hormone cortisol—despite having no idea it was present. The findings suggest our bodies can “sense” these vibrations... Read more

Long before humans spread across the globe, a deadly disease may have quietly shaped where our ancestors lived—and even how we evolved. New research reveals that malaria didn’t just threaten early human survival; it actively pushed populations away from high-risk regions across Africa, fragmenting groups over tens of thousands of years. This separation influenced how different populations met, mixed, and exchanged genes, helping shape the genetic diversity we see today. Read more

Coffee doesn’t just energize—it actively reshapes the gut and mind. Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress. Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety. Together, they show coffee works through multiple pathways beyond just caffeine. Read more

Evolution seems to follow a script more often than expected. Researchers found that distantly related butterflies and moths have reused the same pair of genes for over 120 million years to produce strikingly similar warning colors. Rather than altering the genes themselves, evolution modifies how they’re switched on and off. This discovery hints that life may evolve in more predictable ways than previously believed. Read more

Drugs designed to clear amyloid beta from the brain—once seen as a promising path to slowing Alzheimer’s—may not actually help patients in any meaningful way, according to a major review of over 20,000 participants.

GLP-1 drugs like semaglutide—best known for treating diabetes and driving weight loss under the brand names Ozempic and Wegovy—may also deliver a surprising mental health boost.

A new study suggests depression may soon be detectable through a simple blood test—by tracking how certain immune cells age. Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and cognitive symptoms of depression, like hopelessness and loss of pleasure, rather than physical symptoms such as fatigue.
