New method to identify symmetries in data using Bayesian statistics      (via sciencedaily.com) 

Scientists have developed a method to identify symmetries in multi-dimensional data using Bayesian statistical techniques. Bayesian statistics has been in the spotlight in recent years due to improvements in computer performance and its potential applications in artificial intelligence. However, this statistical approach requires complex calculations of integrals, which are often considered approximations only. In their new study, the research team successfully derived new exact integral formulas. Their findings contribute to improving the accuracy of methods to identify data symmetries, possibly extending their applications to wider areas of interest, such as genetic analysis.

What killed dinosaurs and other life on Earth?      (via sciencedaily.com) 

Determining what killed the dinosaurs 66 million years ago at the end of the Cretaceous Period has long been the topic of debate, as scientists set out to determine what caused the five mass extinction events that reshaped life on planet Earth in a geological instant. Some scientists argue that comets or asteroids that crashed into Earth were the most likely agents of mass destruction, while others argue that large volcanic eruptions were the cause. A new study reports that volcanic activity appears to have been the key driver of mass extinctions.

Bigger plants don't always equal more nutritious ones      (via sciencedaily.com) 

While increased carbon dioxide levels in the atmosphere encourage plant growth, they also reduce the nutritional value of plants, which can have a larger impact on nutrition and food safety worldwide. Researchers have discovered a new way plants are adapting to the changing climate -- information that can be used to help plants grow strong while also maintaining their nutritional value.

New ice-shedding coating is 100x stronger than others      (via sciencedaily.com) 

To combat the hazards of ice, a mechanical engineer has developed a sprayable ice-shedding material that is 100 times stronger than any others. It's been tested by Boeing under erosive rain conditions at 385 miles per hour and outperformed current state-of-the-art aerospace coating technologies.

New study reveals mechanism for how disease-spreading prions can jump from one species to another      (via sciencedaily.com) 

In a new study, researchers have identified the structure of protein fibrils linked to a hereditary form of human prion disease. This insight, they say, reveals the mechanism for how prions can jump between some animal species, while retaining a transmissibility barrier between other species.

Nanotubes illuminate the way to living photovoltaics      (via sciencedaily.com) 

Scientists have gotten bacteria to spontaneously take up fluorescent carbon nanotubes for the first time. The breakthrough unlocks new biotechnology applications for prokaryotes, such as near-infrared bacteria tracking and 'living photovoltaics' -- devices that generate energy using light-harvesting bacteria.

Environmental scientists develop a method to turn hazardous acidic industrial wastewater into valuable resources      (via sciencedaily.com) 

Environmental scientists have developed a circular process for eliminating the risk posed by phosphoric acid plant wastewater. The process turns the environmentally toxic wastewater into clean water while recovering valuable acids. Phosphoric acid is the main ingredient in industrial fertilizers, a massive industry worldwide.

Making mini-magnets      (via sciencedaily.com) 

Researchers demonstrated a topological insulator device that opens the way towards observing the quantum anomalous Hall effect. Because the currents generated are resistant to scattering, but very sensitive to applied magnetic fields, they may be used for reducing power consumption in computing applications.

Is climate change disrupting maritime boundaries?      (via sciencedaily.com) 

Coral reef islands and their reefs -- found across in the Indo-Pacific -- naturally grow and shrink due to complex biological and physical processes that have yet to be fully understood. Now, climate change is disrupting them further, leading to new uncertainties for legal maritime zones and small island states. Rising sea levels, coupled with the natural variability of atoll islands and coral reefs, is creating new uncertainty in international law, with geopolitical implications.

Climate change is affecting drinking water quality      (via sciencedaily.com) 

The water stored in reservoirs ensures our supply of drinking water. Good water quality is therefore important -- but is at significant risk due to climate change. In a model study of the Rappbode reservoir in the Harz region, a research team demonstrated how the climate-related disappearance of forests in the catchment area for Germany's largest drinking water reservoir can affect water quality. The problem of such indirect consequences of climate change is seriously underestimated, the scientists warn. Water quality is of critical importance, especially for drinking water reservoirs, as subsequent treatment in the waterworks must continually meet high standards.

Astronomy: Is over-eating to blame for bulges in Milky Way bar?      (via sciencedaily.com)     Original source 

A new simulation conducted on the world's most powerful supercomputer dedicated to astronomy has produced a testable scenario to explain the appearance of the bar of the Milky Way. Comparing this scenario to data from current and future space telescopes will help clarify the evolution of our home Galaxy.

A little strain goes a long way in reducing fuel cell performance      (via sciencedaily.com) 

Researchers report that strain caused by just a 2% reduction in the distance between atoms when deposited on a surface leads to a whopping 99.999% decrease in the speed at which the materials conduct hydrogen ions, greatly reducing the performance of solid oxide fuel cells. Developing methods to reduce this strain will help bring high-performance fuel cells for clean energy production to a wider number of households in the future.

Physicists invoke the cosmological collider to explain why matter, and not antimatter, dominates the universe      (via sciencedaily.com) 

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and 'antimatter' -- particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe cooled. Today's universe is full of galaxies and stars which are made of matter. Where did the antimatter go, and how did matter come to dominate the universe? This cosmic origin of matter continues to puzzle scientists. Physicists have now opened a new pathway for probing the cosmic origin of matter by invoking the 'cosmological collider.'

Hubble finds spiraling stars, providing window into early universe      (via sciencedaily.com)     Original source 

Stars are the machines that sculpt the universe, yet scientists don't fully know how they form. To understand the frenzied 'baby boom' of star birth that occurred early in the universe's history, researchers turned to the Small Magellanic Cloud, a satellite galaxy of the Milky Way. This nearby galaxy has a simpler chemical composition than the Milky Way, making it similar to the galaxies found in the younger universe, when heavier elements were more scarce. This allows it to serve as a proxy for the early universe. Two separate studies -- the first with the Hubble Space Telescope, and the second with the European Southern Observatory's Very Large Telescope -- recently came to the same conclusion. Using different methods, the independent teams found young stars spiraling into the center of a massive star cluster called NGC 346 in the Small Magellanic Cloud. This river-like motion of gas and stars is an efficient way to fuel star birth, researchers say. The teams' results show that the process of star formation in the Small Magellanic Cloud is similar to that in our own Milky Way.
