Considering the immense size of the universe, it's no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen before, and it's challenging what we thought we knew about how stars die.

Climate models suggest that climate change could reduce the Southern Ocean's ability to absorb carbon dioxide (CO2). However, observational data actually shows that this ability has seen no significant decline in recent decades.

Researchers at Karolinska Institutet have discovered how cells can adjust their gene activity to survive when oxygen runs low. The study, published in Nature Cell Biology, reveals that cells use a previously unknown mechanism to control which proteins are produced—and how quickly.

A team of researchers from the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, has developed a sensor that can identify sodium nitrite (NaNO2) in various beverages, including mineral water, orange juice, and wine. This inorganic salt is used as a preservative and fixative to give products such as ham, bacon, and sausages their pink or red color. Depending on the amount, it can cause serious health problems by leading to the formation of nitrosamines, which are carcinogenic compounds.

Many of the world's most important systems, such as the atmosphere, turbulent fluids, and even the motion of planets, behave unpredictably due to chaos and noise. Scientists often study these systems through their "invariant" measures, long-term statistical behaviors, rather than individual paths. While useful, these measures have a fundamental limitation: completely different systems can share the same statistics, making it impossible to identify the underlying dynamics.

The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, with masses of around 100 GeV/c2), primordial black holes, and ultralight axion-like particles (mass of 10-22 to 1 eV/c2). In the latter case, dark matter behaves like a wave, described by a Schrödinger equation, rather than as a collection of point particles. This generates specific behaviors at small scales, while following standard dynamics (CDM) at large scales.

This week, researchers reported the discovery of four Late Bronze Age stone megastructures likely used for trapping herds of wild animals. Physicists have proven that a central law of thermodynamics does not apply to atomic-scale objects that are linked via quantum correlation. And two Australian Ph.D. students coded a software solution for the James Webb Space Telescope's Aperture Masking Interferometer, which has been producing blurry images.

Ukraine's Volodymyr Zelenskyy might have come to the White House for Tomahawks, but President Donald Trump and he agreed against escalation and a move toward peace, with Trump issuing a directive to Russia and Ukraine to "stop where the are."
