Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering objects exist beyond our Solar System. The find suggests fragm

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold dark matter, providing long-sought answers about the in

Jezero Crater’s rocks reveal three stages of water activity, shifting from hostile acidic fluids to more life-friendly alkaline ones. Perseverance’s discoveries guide future sampling and strengthen the hunt for past life on Mars.

Scientists at Michigan State University have discovered how to use ultrafast lasers to wiggle atoms in exotic materials, temporarily altering their electronic behavior. By combining cutting-edge microscopes with quantum simulations, they created a nanosca

America already mines all the critical minerals it needs for energy, defense, and technology, but most are being wasted as mine tailings. Researchers discovered that minerals like cobalt, germanium, and rare earths are discarded in massive amounts, even t

Using laser light instead of traditional mechanics, researchers have built micro-gears that can spin, shift direction, and even power tiny machines. These breakthroughs could soon lead to revolutionary medical tools working at the scale of cells.

Astronomers have long relied on supercomputers to simulate the immense structure of the Universe, but a new tool called Effort.jl is changing that. By mimicking the behavior of complex cosmological models, this emulator delivers results with the same accu

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered across three eras shortly after the Big Bang, they mapped

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, these worlds likely retain only a few percent of water at t

A sweeping investigation has revealed widespread fraud in mathematics publishing, where commercial metrics and rankings have incentivized the mass production of meaningless or flawed papers. The study highlights shocking distortions—such as a university w

芬兰科学家精确测量了已知最重的质子放射核素，发现了稀有同位素砹-188。该核素呈现出独特的原子核形态，可能揭示一种新型核相互作用。

科学家首次通过实验证明，即便单个光子分裂为两个时角动量依然守恒，将量子物理学推向其基本极限。研究团队使用超精密设备捕获了这种堪比大海捞针的微妙过程，在光子层面验证了这项基础自然定律。
