Researchers discover 'doorways' into brain cells

Researchers discovered specialized domains on nerve cell surfaces that regulate the entry of molecules, revising a long-held theory. These 'endocytic zones' control receptor transport and are also entry points for nutrients and pathogens, offering new insights into brain development and neurological disorders.

Agreements for industry-sponsored clinical trials often fail to protect researchers’ independence

A study by Duke University Medical Center found that agreements between academic medical centers and industry sponsors rarely include provisions to protect researchers' independence, access to data, and editorial control. This can lead to compromised scientific integrity and a lack of transparency in clinical trials.

Superconducting lithium

Researchers establish superconductivity in lithium at pressures greater than 30 GPa, with critical temperatures ranging from 9 K to 16 K. This finding contradicts theory and sparks interest in searching for high-temperature superconductivity in light element compounds.
