Rewriting the History of Plant Evolution: New Study Uncovers Intriguing Insights Into Plant Biology
A new study reveals that plant evolution consists of long periods of gradual changes punctuated by brief bursts of large-scale innovations, particularly in response to environmental challenges. This challenges the previously held notion that plants evolved with a sudden change early in their history, similar to animals.A recent study has uncovered intriguing insights into the

KeelThis dream-like Hubble Space Telescope Picture of the Week features the galaxy known as NGC 3156. It is a lenticular galaxy, meaning that it falls somewhere between an elliptical and a spiral galaxy. It lies about 73
ChatGPT’s Strong Left-Wing Political Bias Unmasked by New Study
A study by the University of East Anglia reveals a significant left-wing bias in the AI platform ChatGPT. The study highlights the importance of neutrality in AI systems to prevent potential influence on user perspectives and political dynamics.A research study identifies a significant left-wing bias in the AI platform ChatGPT, leaning towards US Democrats, the
Regular Napping Linked to Increased Brain Size
Daytime napping could preserve brain health and slow brain shrinkage with age, according to a study by UCL and the University of the Republic in Uruguay. Using genetic data, researchers found that those genetically inclined to nap had larger brain volumes, which is linked to lower dementia risk.Taking daytime naps might help maintain brain health
Table Salt – The Surprising Secret Ingredient Revolutionizing Chemical Recycling
Researchers have demonstrated that table salt can be a potent and cost-effective catalyst for recycling plastics, especially in the pyrolysis process. This simple solution could drastically reduce costs and improve efficiency in plastic recycling, even outperforming much pricier catalysts currently in use.Muhammad Rabnawaz, an associate professor at Michigan State University’s esteemed School of Packaging and
Scientists used machine learning to perform quantum error correction
The “qubits” that make up quantum computers can assume any superposition of the computational base states. This allows quantum computers to conduct new tasks in conjunction with quantum entanglement, another quantum property that joins several qubits in ways that go beyond what is possible with classical connections. The extraordinary fragility of quantum superpositions is the
Groundbreaking research in Nature Genetics unveils the biggest-ever study on the genetics of random blood sugar levels that fluctuate throughout the day and night. This extensive study involved nearly half a million people from diverse backgrounds. It has identified new genetic variations that impact these random blood sugar levels. The research team, led by Professor

Letter: Grateful for ‘Space Greta’
Credit: SpaceNews I was so happy to see SpaceNews recognize several of the many young, talented, hardworking, selfless professionals who are fueling efforts to make space safer for the generations to come in the story “Stand Up, Space Greta.” So often, the loudest, oldest, and most flamboyant “experts” suck all of the air out of
