Flying cars have been a popular concept in sci-fi and fantasy stories for over a century, but they have not yet become a reality. However, the technology to create flying cars already exists, and hundreds of companies are working on prototypes. These vehicles would combine helicopter and airplane technology, using rotating blades or propellers for vertical takeoff and then flying like a normal airplane. The main barriers to widespread use of flying cars are cost, safety regulations, and the need for more efficient and sustainable power sources. It may still be 10 to 20 years before flying cars become common, and a rideshare service for flying cars could be more practical than individual ownership. [Extracted from the article]

Researchers have discovered a new, more environmentally friendly way to dye denim blue using a compound called indican. Indican, found in indigo plants, dissolves in water and requires fewer harsh chemicals compared to traditional indigo dyeing methods. The researchers found that when indican was exposed to sunlight, it converted to indigo, resulting in blue yarn. This light-driven process could significantly reduce the environmental impacts of denim dyeing, with the enzyme-based method estimated to cut harmful impacts by over 90 percent. Further testing is needed before these methods can be implemented in factories, but they are expected to be cost-effective and accessible to all consumers. [Extracted from the article]

A report published by the United Nations Environment Programme highlights the drastic decline of migratory fish species. The report reveals that 97% of CMS-protected fish species, approximately 56 species, are facing extinction. The main factors contributing to fish declines include bycatch, overfishing, and pollution. The report also emphasizes the need to protect migratory species on land and in water, and suggests strategies such as attaching LED lights to nets to deter certain fish. The goal of the report is to guide conservation efforts and raise awareness about the declining populations of migratory species. [Extracted from the article]

Emo, a robot developed by researchers at Columbia University, has been trained to predict and mirror human smiles in real time. Unlike most humanoid robots, Emo can smile back at a person without a noticeable delay. By analyzing human facial expressions and using cameras and actuators, Emo can accurately recreate facial expressions and potentially serve as a source of connection for lonely individuals. The robot's blue skin and more timely facial expressions may also help alleviate the uncanny valley effect often associated with humanoid robots. Future iterations of Emo could be equipped with generative AI chatbot functions and improved lip movement to enhance its capabilities as an engaging companion. [Extracted from the article]

A recent study published in Science Immunology suggests that nerve growth from immune responses to urinary tract infections (UTIs) may be responsible for the lingering pain experienced by patients even after the infection has been treated. Researchers collected urine samples from women with recurrent UTIs and found signs of nerve activation compared to samples from women without recurrent UTIs. In mice, induced multiple UTIs resulted in a significant growth of nerves. The study suggests that understanding how UTIs influence nerve growth could lead to more effective pain management in the future. [Extracted from the article]

"Space: The Longest Goodbye" is a documentary that explores the mental health challenges faced by astronauts during long-duration space missions. The film follows astronauts Kayla Barron and Cady Coleman, highlighting the emotional toll of being separated from loved ones and the constant surveillance they experience. It also discusses coping strategies being developed, such as the use of friendly robots to combat loneliness. The documentary provides a nuanced and emotional portrayal of the realities of being an astronaut. [Extracted from the article]

Experiments on tadpoles have provided insights into intestinal malrotation, a birth anomaly that affects as many as 1 in 500 babies in the United States. Researchers found that interfering with tadpoles' metabolism caused their intestines to grow in the opposite direction. The study used frog embryos because their intestines are similar to those of humans, and the researchers exposed them to atrazine, a common herbicide and hormone disruptor. While the study does not prove that atrazine causes intestinal malrotation in humans, it suggests that metabolic disruption may play a role. Additionally, tadpoles given antioxidants before exposure to atrazine developed normal intestines, indicating a potential avenue for further research. [Extracted from the article]

A 3-D fossil of a tree called Sanfordiacaulis densifolia has been discovered, providing rare insight into the structure of forests during the early Mississippian period. The fossil, found in Canada, preserves both the trunk and leaves of the tree, which was approximately 3 meters tall with a 6-meter-wide crown and leaves as long as 3 meters. The short height and large leaves of the tree suggest that it may have been an early subcanopy species, adapted to the dark understory of the forest. Further study of these fossils could provide valuable information about how ancient plants adapted to changing environments. [Extracted from the article]

The article presents information related to students. A teacher describes a girl in her Year 5 class as loner her effort to encourage others to form friendship with the girl has not produced any positive result. Advice by others to solve the problem includes to organize some workshops related to things the girl is good at and another teacher says its fine to be alone sometimes and gives her own example. Also experience of Tim Nixon who is both police officer and teacher is presented.
