You might not think an animal made out of stone would have much to worry about in the way of predators, and that's largely what scientists had thought about coral. Although corallivores like parrotfish and pufferfish are well known to biologists, their impact on coral growth and survival was believed to be small compared to factors like heatwaves, ocean acidification and competition from algae.
Radio telescope reveals thousands of star-forming galaxies in early Universe
The images capture drama billions of years ago in the early Universe—glinting galaxies, glowing with stars that have exploded into supernovas and blazing jets fired from black holes.
The Guardian view on dark skies: we need them
Light pollution is killing insects and birds – and an ancient human connection with the heavenly bodiesSevere light pollution in Britain appears to have fallen, according to the CPRE, the countryside charity. Across a week in February, the charity asked volunteers to look up and count the stars they could see. The results suggest that 51% of participants were experiencing severe light pollution,...
Researchers validate new technique for rapidly diagnosing herbicide-resistant weeds
As the number of weed populations resistant to multiple herbicides continues to soar, it is clear that better tools are needed to help growers rapidly diagnose resistance issues. With more timely access to information, they can take earlier, proactive steps to keep resistant weeds from spreading.
Caught speeding: Clocking the fastest-spinning brown dwarfs
Using data from NASA's Spitzer Space Telescope, scientists have identified the three fastest-spinning brown dwarfs ever found. More massive than most planets but not quite heavy enough to ignite like stars, brown dwarfs are cosmic in-betweeners. And though they aren't as well known as stars and planets to most people, they are thought to number in the billions in our galaxy.
Entropy measurements reveal exotic effect in 'magic-angle' graphene
Most materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic analog in a material known as magic-angle graphene, says a team of researchers from the Weizmann Institute of Science led by Prof. Shahal Ilani, in...
Ancient human migration into Europe revealed via genome analysis
Genetic sequencing dating back 45,000 years shows intermixing with Neanderthals more common than previously thoughtGenetic sequencing of human remains dating back 45,000 years has revealed a previously unknown migration into Europe and showed intermixing with Neanderthals in that period was more common than previously thought.The research is based on analysis of several ancient human remains –...
Machine-learning methods lead to discovery of rare 'quadruply imaged quasars'
With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic "lens" and split into four similar images. Quasars are extremely luminous cores of distant galaxies that are powered by supermassive black holes.

An international team of researchers has studied individual differences in the behavior of red deer. They found that several observed behaviors form a personality component, which they labelled 'Confidence/Aggressiveness'.
Robots can be more aware of human co-workers, with system that provides context

A new context-aware system for robots is ready for implementation on the factory floor. A recent study shows the system is more efficient because it can recognize co-workers and their body shapes, and even predict their movements.
Mosel vineyards are preparing for climate change by sharing their soil with aromatic plants
The landscape of sloping vineyards on the banks of the Mosel River in Germany is a characteristic symbol of a region which cannot be understood without its wine: the Mosel wine region. Tourists from all over the world, especially from the neighboring countries of Belgium, Luxembourg, and The Netherlands visit the area in search of mountains and wine. However, the lack of new generations and the...
Discarded masks litter beaches worldwide, threaten sea life
To the usual list of foul trash left behind or washed up on beaches around the world, add these: masks and gloves used by people to avoid the coronavirus and then discarded on the sand.
Gender inequality study shows women under-represented on marketing academic journal boards
Women are significantly underrepresented in the editorial boards of marketing academic journals, and awards and recognition favor men, new research from the University of Bath School of Management has found.
Foetus in bishop's coffin was probably his grandson
Bishop Peder Winstrup died in 1679, and is one of the most well-preserved human bodies from the 1600s. Researchers at Lund University in Sweden may now have solved the mystery of why a fetus was hidden in his coffin in Lund Cathedral. DNA from the bishop and the fetus, along with kinship analyses, has shown that the child was probably the bishop's own grandson.
The opportunities and risks of digitalization for sustainable development
Digitalisation can support transitions towards a more sustainable society if technologies and processes are designed in line with suitable criteria. This requires a systemic focus on the risks and benefits of digital technologies across the three dimensions of sustainable development: the environment, society, and the economy. This is the conclusion of a study prepared by a team of researchers at...
Study demonstrates the need to monitor the bit area of event horses
It was found that event horses that wear thin or thick bits in events had a greater risk of moderate or severe oral lesions compared to horses wearing medium-sized bits, while straight bits were associated with lesions in the bars of the horse's mouth.
