A new study using CRISPR technology on zebrafish embryos suggests that the evolution of hands and feet involved repurposing ancient genetic programs, particularly those related to our posterior regions, rather than developing entirely new genes.
Experts suggest that constant hand movements, such as wringing or fidgeting, could be a sign of advanced dementia, alongside other symptoms like memory loss and confusion. Recognizing these signs early can help in managing the condition more effectively.
The article ranks prospects in the 2025 NHL Draft across categories like best skaters, shooters, hands, and more, highlighting top players such as Cullen Potter, Matthew Schaefer, and Ryker Lee, and providing insights into their skills and attributes.
Your hands can reveal important clues about your health. Changes in nail appearance, such as clubbing, Lindsay's nails, Terry's nails, and Muehrcke's nails, can indicate various diseases including kidney disease, cirrhosis of the liver, and thyroid conditions. Sweaty palms can be a sign of thyroid problems, while red or purple discoloration on the palms may indicate bacterial endocarditis. Pins and needles in the hand can be a symptom of carpal tunnel syndrome or diabetic neuropathy. Finger length, particularly the ratio between the index and ring finger, can be associated with the risk of developing certain diseases later in life.
The appearance of your hands can provide clues about your overall health and help diagnose underlying conditions. For example, the length of a man's ring finger may indicate the likelihood of developing prostate cancer. Finger clubbing, characterized by increased soft tissue under the nail beds, can be a symptom of serious health conditions such as lung cancer, heart problems, liver disease, and inflammatory bowel disease. Changes in the appearance of fingers or hands should be discussed with a healthcare professional for proper diagnosis and treatment.
Stability AI has announced that the next version of its prompt-based AI image generator, Stable Diffusion, called SDXL 0.9, will produce more photorealistic images and better hands. The new model provides a significant increase in parameter count, allowing for improved results. It will soon be available on Stability AI’s Clipdrop web tool and will be added to the startup’s DreamStudio app. The open-source version of SDXL 1.0 will arrive in mid-July.
