From order to chaos: Understanding the principles behind collective motion in bacteria

Matter and energy from Science Daily Feed - Mon, 03/17/2025 - 1:41pm
Researchers have discovered that bacterial swarms transition from stable vortices to chaotic turbulence through distinct intermediate states. Combining experiments with bacterial swarms, computer simulations, and mathematical modeling, the team clarified the intricate process by which orderly swirling turns to disordered turbulence as the free space available to bacteria increases. These findings provide new insights into active matter physics and could inform future applications in micro-robotics, biosensing, and active fluid-based micro-scale systems.

RNA origami: Artificial cytoskeletons to build synthetic cells

Matter and energy from Science Daily Feed - Mon, 03/17/2025 - 1:40pm
With the long-term goal of creating living cells from non-living components, scientists in the field of synthetic biology work with RNA origami. This tool uses the multifunctionality of the natural RNA biomolecule to fold new building blocks, making protein synthesis superfluous. In pursuit of the artificial cell, a research team has cleared a crucial hurdle. Using the RNA origami technique, they succeeded in producing nanotubes that fold into cytoskeleton-like structures.

Illusion of 'dazzle' paint on World War I battleships

Matter and energy from Science Daily Feed - Mon, 03/17/2025 - 1:37pm
A new analysis of 105-year-old data on the effectiveness of 'dazzle' camouflage on battleships in World War I has found that while dazzle had some effect, the 'horizon effect' had far more influence when it came to confusing the enemy.

Top locations for ocean energy production worldwide revealed

Matter and energy from Science Daily Feed - Mon, 03/17/2025 - 1:37pm
Until now, a global evaluation of ocean current energy with actual data was lacking. Using 30 years of NOAA's Global Drifter Program data, a study shows that ocean currents off Florida's East Coast and South Africa have exceptionally high-power densities, ideal for electricity generation. With densities over 2,500 watts per square meter, these regions are 2.5 times more energy-dense than 'excellent' wind resources. Shallow waters further enhance the potential for ocean current turbines, unlike areas like Japan and South America, which have lower densities at similar depths.

New AI model analyzes full night of sleep with high accuracy in largest study of its kind

Computers and Math from Science Daily Feed - Mon, 03/17/2025 - 1:37pm
Researchers have developed a powerful AI tool, built on the same transformer architecture used by large language models like ChatGPT, to process an entire night's sleep. To date, it is one of the largest studies, analyzing 1,011,192 hours of sleep. The model, called patch foundational transformer for sleep (PFTSleep), analyzes brain waves, muscle activity, heart rate, and breathing patterns to classify sleep stages more effectively than traditional methods, streamlining sleep analysis, reducing variability, and supporting future clinical tools to detect sleep disorders and other health risks.

Age of upcoming asteroid flyby target

Space and time from Science Daily Feed - Mon, 03/17/2025 - 1:36pm
New modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit and spin properties have undergone significant evolution since. When NASA's Lucy spacecraft flies by this approximately three-mile-wide space rock on April 20, 2025, the data collected could provide independent insights on such processes based on its shape, surface geology and cratering history.

Magnetic microalgae on a mission to become robots

Matter and energy from Science Daily Feed - Mon, 03/17/2025 - 1:35pm
Scientists have developed a single-cell green microalgae coated with magnetic material. This miniature robot was put to the test: would the microalgae with its magnetic coating be able to swim through narrow spaces and, additionally, in a viscous fluid that mimics those found in the human body? Would the tiny robot be able to fight its way through these difficult conditions?
