Peering into the tendrils of NGC 604 with NASA's Webb      (via sciencedaily.com)     Original source 

The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.

Nasa’s Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists      (via sciencedaily.com)     Original source 

When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.

AI-generated food images look tastier than real ones      (via sciencedaily.com)     Original source 

Researchers have announced an intriguing discovery -- consumers generally prefer AI-generated images of food over real food images, especially when they are unaware of their true nature.

Balancing training data and human knowledge makes AI act more like a scientist      (via sciencedaily.com)     Original source 

When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training -- such as the laws of physics --could make them more efficient and more reflective of the real world. However, helping the AI assess the value of different rules can be a tricky task.

CSI in space: Analyzing bloodstain patterns in microgravity      (via sciencedaily.com)     Original source 

As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in microgravity and the unique challenges of bloodstain pattern analysis aboard spacecraft.

Interstellar signal linked to aliens was actually just a truck      (via sciencedaily.com)     Original source 

Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.

Method rapidly verifies that a robot will avoid collisions      (via sciencedaily.com)     Original source 

A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.

Earth's earliest forest revealed in Somerset fossils      (via sciencedaily.com)     Original source 

The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.

Drawings of mathematical problems predict their resolution      (via sciencedaily.com)     Original source 

Solving arithmetic problems, even simple subtractions, involves mental representations whose influence remains to be clarified. Visualizing these representations would enable us to better understand our reasoning and adapt our teaching methods. A team has now analyzed drawings made by children and adults when solving simple problems. The scientists found that, whatever the age of the participant, the most effective calculation strategies were associated with certain drawing typologies. These results open up new perspectives for the teaching of mathematics.

Baby quasars: Growing supermassive black holes      (via sciencedaily.com)     Original source 

The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.

Bee-2-Bee influencing: Bees master complex tasks through social interaction      (via sciencedaily.com)     Original source 

Bumblebees successfully learned a two-step puzzle box task through social observation. This task was too complex for individual bees to learn on their own. Observing trained demonstrator bees performing the first unrewarded step was crucial for successful social learning. Individual bees failed to solve the puzzle without previous demonstration, despite extensive exposure.

Discovery tests theory on cooling of white dwarf stars      (via sciencedaily.com)     Original source 

Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.

Do some electric fish sense the world through comrades' auras?      (via sciencedaily.com)     Original source 

It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. Biologists have found evidence that this kind of collective sensing occurs in close-knit groups of African weakly electric fish, also known as elephantnose fish. This instantaneous sharing of sensory intelligence could help the fish locate food, friends and foes.

Tiny worms tolerate Chornobyl radiation      (via sciencedaily.com)     Original source 

A new study finds that exposure to chronic radiation from Chornobyl has not damaged the genomes of microscopic worms living there today -- which doesn't mean that the region is safe, the scientists caution, but suggests that these worms are exceptionally resilient.
