Nuclear fusion is the energy source of the future, but tokamaks, the most common technological approach to fusion, seem to not be making much progress. But luckily for our clean energy dreams, a different but related alternative – the stellarator – has made strides recently. Let’s take a look.

Иногда совместное заражение двумя видами паразитоидов может позволить осе успешно развиться даже в неподходящем хозяине. Такие случаи фиксировались только для видов, не разделяющих общий ареал. Японские исследователи сумели доказать, что теоретически успешный мультипаразитизм возможен даже в природных условиях. Они назвали эту стратегию «пиратским паразитизмом».

Soon after Stephen Hawking died in 2018, his collaborator Thomas Hertog published his posthumous “final theory.” Basically, the theory builds on the idea of eternal inflation, which says that new universes are constantly being created from an even-larger sea of quantum fluctuations. Hawking’s theory sought to explain that these births happened more gradually and less disruptively, bringing the

The world is slowly running out of Helium, and has already seen four helium shortages. It’s a problem because Helium is essential in the creation of microchips, and we need plenty of those to keep artificial intelligence running. Luckily – and surprisingly – researchers have recently published a paper claiming that the Earth’s core is actually full of the stuff. Let’s take a look.

Исследование трех внутренних планет в системе красного карлика L 98-59 показало, что планета L 98-59 b, судя по всему, окружена оболочкой из вулканических газов, свидетельствующей о мощном приливном разогреве. Планета L 98-59 d — что-то среднее между скалистыми планетами и мининептунами, — однако плотная серосодержащая атмосфера есть и на ней, что весьма неожиданно.

A few months ago, sensors detected a neutrino traveling through the Mediterranean Sea with 100 peta-electronvolts worth of energy. Some researchers claim that this event proves that Stephen Hawking’s theory of black hole evaporation is correct. Does this make sense? Let’s take a look.

We still don’t know what “consciousness” actually means. But in a new study, researchers have used the equations of quantum mechanics to determine a brain’s “criticality,” a measure which allows them to separate waking brains from sleeping ones. I think they’re onto something. Let’s take a look.

You would think that the title of “the world’s laziest power source” would go to solar panels, but scientists have successfully tested an even lazier power source that generates power from the Earth’s magnetic field. It doesn’t even need to go outside! Sounds too good to be true? Let’s take a look.

В коммуникации бонобо обнаружено свойство, называемое «нетривиальной композиционностью». Это значит, что смысл составного высказывания формируется на основе смыслов составляющих его элементов, но не сводится к простому суммированию этих смыслов. Ранее это свойство не было надежно документировано ни у одного вида животных, кроме человека.

When I started my career in physics, I didn’t plan on becoming particle physicists’ enemy number one, but somehow I have. Here’s how it all happened.

Сверчки, обитающие на Гавайских островах, долгое время довольствовались одной песней для привлечения самок, но лишь до тех пор, пока на острова не вселилась паразитическая мушка, выслеживающая сверчков по их стрекотанию и в конечном итоге убивающая незадачливых певцов. Чтобы справиться с этой угрозой, сверчкам пришлось быстро эволюционировать, придумав песни, звучание которых недоступно для восприятия паразита.

All across the globe, new nuclear power plants are being built and some shuttered plants are even being revived as countries look for more ways to create clean, cheap electricity. But the nuclear renaissance faces problems.

CERN wants to build a new particle collider which will smash protons together at roughly 6 times the energies seen at the Large Hadron Collider. This project is likely to cost more than $40 billion and wouldn’t be operational until the 2070s. Let’s take a look at why a growing number of physicists are saying we’d be better off without it.
