Blue damselfish are abundant in urban waters, but genetic analysis shows high levels of gene activity. Their striking blue hue makes them easy to spot even along Okinawa's heavily urbanized coastlines. Despite being easily found, the fish's genes reveal a hidden cost to living in human-impacted environments. #Blue #Okinawa #Despite

Cephalopods like octopuses, squid, and cuttlefish have evolved large and complex brains that can solve problems and change color quickly. Their brains are made up of a unique structure called the 3D genome, which may be responsible for their advanced abilities. The study suggests that this "entanglement" in the 3D genome is key to their intelligence and behavior. #Cephalopods

Anthropic has banned cruel treatment of its AI system Claude. The ban comes after a debate about AI consciousness. Users are no longer allowed to test the limits of Claude's language understanding by using it in ways that are "needless or abusive". This move aims to prevent artificial intelligence from being treated with cruelty. #Anthropic #AI #Claude

Scientists discover 180,000 giant tortoises on one Seychelles island. The Aldabra population is now much larger than Seychelles' human population due to a decades-long conservation effort. The large number of tortoises was found through a recent survey. This free-roaming population is the world's largest. #Scientists #Seychelles

Lipoprotein(a) linked to carotid artery plaque buildup in people with high levels of the protein in their blood. Elevated lipoprotein(a), also known as Lp(a), is associated with atherosclerosis, which can cause heart attacks and strokes. High levels of Lp(a) can increase risk of cardiovascular disease. This may help doctors predict which patients are at higher risk. #Lipoprotein #Elevated #Lp

Scientists at Imperial College London have developed a new technique to measure oxygen production in real-time during solar water splitting. This has revealed significant hidden losses in the process. Real-time measurements showed that oxygen production does not always match electrical current levels. #ImperialCollege #Scientists #London

Eating food items in a particular order can affect how body manages sugar and insulin after eating. This idea, called meal sequencing, suggests that the order of consuming different types of food can impact their effect on blood sugar levels. Foods with low glycemic index are typically eaten first, followed by those rich in carbohydrates. #Eating #Foods

Medical devices often require redesigning to be reused or recycled. A recent study suggests this could help reduce electronic waste globally. Many medical devices are currently designed with a "single-use" approach, which can lead to significant waste generation. The study emphasizes the importance of sustainable design in medical device production. #Medical
