Marine heat waves are extreme high temperature events in which sea surface temperatures are abnormally warm and last for days to months. Global warming is making such events more frequent and more intense, with impacts throughout the marine food web, from phytoplankton to top predators. As the basis of the marine food web, phytoplankton supports most of the ocean's primary productivity through photosynthesis, and its changes will affect fishery resources and ocean carbon sinks through cascade effects. The western and central equatorial Pacific has previously been considered to be slightly affected by marine heat waves. The average annual heat wave days in this area are only 22, and the average intensity is only 1.2°C, which is far lower than most sea areas in the world, so it is regarded as a "safe haven" for marine heat waves.

Understanding how domestication reshapes brain structure and function remains a fundamental question in evolutionary biology. The hippocampus is a key brain region involved in memory and stress regulation, and it has been thought to undergo "simplification" during domestication. However, the cellular mechanisms underlying these changes remain poorly understood. In a study published in PNAS on Sept

Recently, the Hefei Institute of Physical Sciences, Chinese Academy of Sciences, has made progress in research on multifunctional electromagnetic wave absorbing superstructures. The team proposed a machine learning-assisted "material-structure-function" collaborative design strategy, using fused deposition modeling 3D printing technology to integrate the polyamide 6/carbon fiber composite (PACF) absorbing unit, low-loss pure polyamide 6 (N-PA) spacer layer and laser-induced PACF (LI-PACF) functional backplane to build a superstructure with multi-level resonant gradient impedance, achieving broadband and wide-angle microwave absorption from 2 to 40 GHz, with both structural load-bearing and electrothermal de-icing capabilities.

Natural products are an important source of modern therapeutic drugs. Their unique skeleton structure, abundant functional groups and multiple chiral centers form the chemical basis for a wide range of biological activities. In the later biosynthesis of such active natural products, iron(II)/2-oxoglutarate-dependent (Fe/2OG) enzymes can precisely introduce pharmacophore groups through a variety of reactions. Among them, the carbon-carbon bonding reaction catalyzed by this enzyme family can build a molecular skeleton with complex structure and significant biological activity. However, the related reaction process is complicated, and its mechanism of action is still unclear so far. In-depth analysis of the catalytic mechanism of this type of enzyme is of great significance for natural product biosynthesis research, new drug development and rational transformation of biocatalysts.
Asteroid impact is a natural disaster with low probability but complex disaster chain. The impact is accompanied by extreme dynamic effects such as ultra-high temperature, ultra-high pressure, ultra-high speed, etc., which will produce a large amount of sputtering dust. Sputtered dust is ejected into the atmosphere at high speed, and some dust enters the stratosphere and spreads, which may cause global environmental effects. Conducting research on the entire process from impact cratering to sputtering dust is of great significance to the study of near-Earth asteroid defense and Earth evolution. At present, due to technical and cost constraints, it is difficult to simulate real working conditions in indoor ultra-high-speed impact tests, and numerical simulation has become the main research method. However, most existing research focuses on a single process and lacks a systematic analysis method covering the complete chain of sputter dust formation - dust tropospheric movement - dust stratospheric diffusion.

The human body is a marvel of remake and renewal. We regularly replace some of our estimated 37 trillion cells – about 300 billion or 1 percent of our cells each day - with healthy substitutes. We remove damaged or aging, senescent cells and cellular debris from our organs and tissues every second of the day. How important is it that cellular waste be properly removed?

The pigments that give beets their red color may have helped a major group of flowering plants repeatedly adapt to dry environments, setting the stage for the evolution of traits that allowed plants to adapt to some of the harshest environments on Earth, according to a University of Michigan study.

Researchers at the Swammerdam Institute for Life Sciences (SILS) of the Faculty of Science have uncovered how mammary-gland cells decide when to activate Wnt4, a gene with a central role in mammary-gland development. Their findings reveal how distant stretches of non-coding DNA work together in three dimensions to control gene activity.

In the past two decades, research on black hole thermodynamics has revealed the similarity between black holes and fluid systems—the existence of a small black hole-large black hole first-order phase transition in charged Anti-de Sitter (AdS) black holes. However, a key question remains unresolved - what thermodynamic behavior does a black hole exhibit in the "supercritical" region above the critical point? For a long time, people have known little about this, and the existing supercritical phase transition lines are not universal.
Standard DNA barcodes are widely used in fields such as biodiversity protection and traceability due to their advantages of strong universal primer adaptability and low sequencing costs. For closely related species, complex taxa with frequent hybridization and recent radiation evolution, standard DNA barcodes cannot meet the needs of accurate identification due to limited sequence variation and insufficient resolution. Although the strategy of shallow genome sequencing to obtain the complete plastid genome (super barcoding) has improved the identification rate of some difficult taxa, the uniparental inheritance characteristics of the plastid genome make it limited in the analysis of introgressed taxa.
Boron plays an important role in glass and ceramic manufacturing, agricultural production and other fields. Although the salt lakes in Qinghai and Tibet are rich in liquid boron ore, the high-salt environment and the reactive inertness of boric acid molecules make efficient and selective extraction of boron challenging.

As it tries to defend itself from stroke, the brain can paradoxically trigger the formation of tiny new clots in minor blood vessels, damaging tissue even after the original culprit has been removed, new research shows. The findings help explain why nearly half of treated stroke patients don’t recover — and identify potential new treatments.
