Analysis of woolly mammoth remains shows that ancient humans primarily killed females, possibly because they were easier to hunt in smaller herds. This discovery provides new insight into human hunting strategies and their role in the mammoths' extinction.
Researchers have developed a flexible sensor based on origami folding principles that can be worn on the body to continuously track vital signs like heart rate and breathing. The design allows the sensor to stretch and move with the skin, making it more comfortable and reliable for long-term health monitoring. This advancement could lead to cheaper, more accessible wearable devices for chronic disease management and early detection of health issues.
A descendant of Henrietta Lacks reflects on her enduring legacy and the impact of Rebecca Skloot's book "The Immortal Life of Henrietta Lacks." The conversation highlights ongoing ethical questions about medical consent and the use of human tissue in research. This matters because Lacks' cells revolutionized medicine, yet her family faced injustice that still resonates today.
District cooling systems, which distribute chilled water from a central plant to multiple buildings, are being explored as a way to combat rising urban temperatures. The approach could reduce energy use and relieve pressure on electrical grids during heatwaves. As cities face more frequent extreme heat, this technology offers a potential scalable solution for cooling without relying solely on individual air conditioning.
Quantum computers are transitioning from experimental devices to practical tools for scientific research. Researchers are using them to solve specific problems that classical computers struggle with, such as simulating molecular interactions. This milestone could accelerate breakthroughs in fields like chemistry, materials science, and drug discovery.
A first-of-its-kind drug for Guillain-Barré syndrome works by selectively switching off a specific part of the immune system. This targeted approach offers a new treatment option for the rare autoimmune disorder, which attacks the peripheral nerves. The innovation matters because current therapies are broad and often have severe side effects.
Scientists are increasingly questioning the cosmological principle, the assumption that the universe is uniform on large scales. New observational anomalies suggest this bedrock law may not hold, potentially forcing a major rethink of our understanding of the cosmos and the standard model of cosmology.
Researchers have identified cases of flat head syndrome in Iron Age skeletons, indicating the condition was present in ancient populations. This discovery offers new insights into early childhood care and cultural practices in prehistoric Europe.
Researchers analyzed somatic mutations in human brains to map the developmental origins of microglia, the brain's immune cells. The findings show how microglia are maintained throughout aging, offering insights into their roles in age-related neurological diseases and brain health.
