Over 120 years ago, Henry Ernest Dudeney posed the famous dissection problem of transforming a triangle into a square by cutting it into as few pieces as possible. In a new study, researchers have finally proved that the original solution, which involves only four pieces, is optimal by using a new proof technique. This technique shows for the first time that it is possible to prove the optimality of the solution to a dissection problem.

A Japanese study has found that the use of continuous glucose monitoring (CGM) devices, equipped with sensors that alert diabetics when their blood sugar levels drop, can potentially make diabetic drivers safer on the road. Those who used the devices had lower incidences of low blood sugar and reported increased confidence in driving.

Scientists have uncovered a key finding to one of water's unique properties: at high pressure and low temperature, liquid water separates into two distinct liquid phases -- one high-density and one low-density.

Researchers have developed PhyloFrame, a machine-learning tool that uses artificial intelligence to account for ancestral diversity in genetic data.

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis. Researchers provide a mechanism to explain precursor oxygenation events, or 'whiffs,' which may have opened the door for this to occur. Their findings suggest volcanic activity altered conditions enough to accelerate oxygenation, and the whiffs are an indication of this taking place.

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide.

Researchers have developed an AI-based learning system that recognizes strengths and weaknesses in mathematics by tracking eye movements with a webcam to generate problem-solving hints. This enables teachers to provide significantly more children with individualized support.

Despite having recently officially ended its science operations in January, Gaia, one of the most prolific star explorers ever, is still providing new scientific insights. A recent paper pre-published on arXiv (which has not been peer-reviewed but was submitted to the Astrophysical Journal) took another look at some Gaia data to try to find a unique type of astronomical entity - white dwarf stars that are paired up in a binary with a main sequence one. By applying a machine learning technique called a "self-organizing map," they found 801 new white dwarf-main sequence (WDMS) binaries, increasing the total number ever found by over 20%.

With the help of the world's most powerful X-ray laser, a research team has achieved an important breakthrough: Using the example of the pharmaceutically active substance 2-thiouracil, they applied a long-established imaging technique to complex molecules. Although 2-thiouracil is no longer applied therapeutically, it is part of a group of chemically similar active substances that are used today as immunosuppressants or cytostatics. The study shows how UV radiation deforms 2-thiouracil, making it dangerously reactive.

A recent study suggests that limiting screen time and promoting physical activity from childhood may help safeguard mental health in adolescence. The findings are particularly significant given that mental health problems affect up to 30% of young people and pose a growing societal challenge.

Researchers have achieved a remarkable result: capturing and studying phase changes in quantum hardware, which hold hold promise for next-generation technologies like quantum computing and ultra-sensitive sensors.

AI models often rely on 'spurious correlations,' making decisions based on unimportant and potentially misleading information. Researchers have now discovered these learned spurious correlations can be traced to a very small subset of the training data and have demonstrated a technique that overcomes the problem.

Newly achieved precise control over light emitted from incredibly tiny sources, a few nanometers in size, embedded in two-dimensional materials could lead to remarkably high-resolution monitors and advances in ultra-fast quantum computing, according to an international team.

The latest 8-9 minute comedy/news bit hasn’t yet been posted on YouTube, but there is a two-minute chuckle on new posters reflecting America’s new set of allies. It’s called “Rosie the Pivoter,” and here it is:

A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark matter.

When downed trees are attacked by beetles, the wood becomes more flammable, demonstrating another way insects can alter the risk of wildfires
