A Zen discovery: Unrusted iron in ocean

A team of scientists has made a groundbreaking discovery that challenges the long-held assumption about oceanic iron cycles. They found that organic compounds can capture some iron spewed by hydrothermal vents, enabling it to be carried away in seawater and reaching the surface, where it can nourish marine life more efficiently.

Revolutionary microchip uses 30 times less power

Scientists have created a microchip that uses 30 times less electricity while running seven times faster than today's technology, thanks to probabilistic logic. This technology has significant implications for the IT industry's carbon footprint, potentially reducing energy consumption in devices such as cell phones and medical implants.

Scientists deconstruct cell division

Researchers have identified two proteins, dynein and Nudel, as crucial for regulating the assembly of the spindle matrix during mitosis. This finding broadens our understanding of how cells control critical events during division. Understanding spindle assembly is essential to comprehend cell fate choices and development.

That gut feeling may actually reflect a reliable memory

A new Northwestern University study uses brain-reading technology to show that people can be more accurate in recognizing familiar images when distracted or guessing than when paying full attention. The research suggests that implicit recognition may play a significant role in everyday decision-making and problem-solving.
