We finally have some encouraging news on Great Barrier Reef water quality

Imagine a plume of brown sediment washed off the land into Queensland rivers and carried out to sea. Here, it can settle on seagrass and inshore corals, potentially smothering them. River water often also carries nitrogen from fertilizer residue, which can fuel algal growth and damage coral health.

Team identifies an evolutionarily conserved enhancer that regulates tendon and ligament development

A research team has uncovered fundamental molecular mechanisms governing the formation of tendons and ligaments, which are essential for musculoskeletal integration. Understanding these mechanisms could pave the way for the regeneration of tendons, ligaments and their attachment sites, known as entheses, which have limited capacity for functional repair after injury because of their poor vascularization.

Virtual reality reveals glassfish synchronize through split-second copying of single neighbors

For centuries, scientists have been fascinated by the remarkable coordinated movements of flocking birds, swarming insects and schooling fish. Researchers have studied these natural phenomena to understand the rules of interactions between individuals that can produce complex group-level behavior. A collaboration of physicists and neurobiologists at the University of California San Diego has been studying schools of micro glassfish (Danionella cerebrum) to understand how the interactive mental p

Innovative etching method for silicon: Higher precision through interlayer

In micro- and nanotechnology, highly precise components with tall, narrow structures (high aspect ratios) made from semiconductor materials like silicon are important. A promising fabrication method is gas-phase metal-assisted chemical etching (MacEtch). In this plasma-free process, a thin metal layer defines the pattern on the silicon substrate. The etching step takes place in a chemical environment, where the reaction occurs only at the interface between the metal and silicon. The metal cataly

How plants use scoop-shaped pores to distribute their pollen efficiently

Bees are the most important pollinators of flowering plants, and approximately 10% of flowering plants are functionally specialized for buzz pollination. Buzz pollination is a mechanism in which pollen can be extracted from flowers only through the application of mechanical vibrations. Many important crops, such as tomatoes, eggplants and blueberries, are buzz-pollinated because they conceal their pollen in so-called poricidal anthers

Ramped fields create more robust entanglement between trapped-ion qubits

While quantum computing could be the future, it is currently plagued by finicky hardware. To make the technology practical, researchers must demonstrate that it consistently and continuously works and performs at scale. In a new study, published in Physical Review Letters, researchers at Lawrence Livermore National Laboratory (LLNL) and the Ion Storage Group at the National Institute of Standards and Technology in Boulder, Colorado, created a robust process for entangling trapped-ion qubits.

Unexpected source of genetic diversity found in human sperm

Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome Sanger Institute, the University of Cambridge and their collaborators found that one type of genetic recombination involving chromosomes, called non-crossover gene conversion, happens before the cell divisions that produce sperm.

Sunscreen for lakes and dams: Could a thin floating layer of nanomaterial shield water from evaporation?

Water stored in dams and reservoirs for humans to use often evaporates, especially in hot regions like southern Africa. Rising temperatures speed up evaporation, leaving less water for people, farming and industry. Daniel Kwasi Kpeglo has just completed a Ph.D. in physics. He explains his laboratory research into a new design

Permafrost thaws worldwide as active layers deepen from 2000 to 2024

An international study led by researchers at the George Washington University indicates clear global evidence that permafrost is thawing across much of the planet. Using more than two decades of field observations from 156 monitoring sites across the Arctic, Antarctic and high-mountain regions, the study found increases in the thickness of the active layer, the uppermost layer above permafrost that thaws and refreezes each year. The findings confirm that permafrost degradation accelerated global

Why banks in Ghana make little use of AI for climate action decisions

Artificial intelligence could help evaluate climate protection projects more effectively and channel funding more precisely to where it is needed. Nevertheless, banks and insurance companies in Ghana have so far made very little use of the technology. A new study conducted at the Brandenburg University of Technology Cottbus-Senftenberg (BTU) in collaboration with the Durban University of Technology in South Africa investigated the reasons behind this. The study is published in Discover Sustainab
