Everyday experience tells us that light reflected from a perfectly flat mirror will give us the correct image without any deformation. Interestingly, this is not the case when the light field itself is structured in a complex way. Tiny deformations appear. These have now been observed in the laboratory. The results confirm the prediction of this fundamental optical effect made more than a decade ago. They also show how it can be used, for example, as a method for determining material properties.

История открытия Америки Христофором Колумбом звучит как хороший сценарий для фильма. История открытия Америки викингами ещё до Колумба звучит как ещё один хороший сценарий для фильма. Есть и более прозаичная третья версия, о которой вы, скорее всего, никогда не слышали, потому что она наиболее вероятна, и при этом в слишком невыгодном свете выставляет историю официальную и её авторов.Задолго до Колумба ...Португальцы открыли острова Зелёного Мыса около 1460-го года, а Азорские...

A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was likely carried in and maintained by human ancestors. The discovery pushes back the timeline for fire use and reveals surprisingly sophisticated behavior long before humans could create fire on... Read more ›

A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after being isolated for roughly 20,000 years. Surprisingly, despite their small population, they have retained much of their genetic diversity. Read more ›

Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny “footprints of death” packed with newly discovered particles that help guide the immune system to clean up the remains. But researchers found that influenza viruses can exploit this process, hiding inside these microscopic packages and potentially using them to spread to nearby cells. Read more ›

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mice, the animals became unusually distractible—similar to what is seen in ADHD—but regained normal focus as soon as the neurons were reactivated.

What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastness of the universe and the likely existence of countless alien civilizations, they suggest it would be surprisingly Earth-centric to assume that only Earth-like biology can support conscious...

Osteopenia is a common but often overlooked condition that causes bones to become less dense and more fragile. Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and inactivity can all contribute to bone loss. Fortunately, exercise, adequate calcium and vitamin D, and other healthy habits can slow or even partially reverse the decline. Read more ›

NASA’s Lucy spacecraft discovered that asteroid Donaldjohanson is a wobbling, peanut-shaped relic born from a violent collision and slowly reshaped by the subtle force of sunlight. It also carries traces of ancient water, making it an important clue to the solar system’s mysterious past. Read more ›
