New research indicates that a common heart drug

Researchers at Boston University School of Medicine discovered that diltiazem, a calcium channel blocker, disrupts the connection between dopamine and glutamate in the brain, driving cocaine cravings. The study provides new insights into the mechanisms of cocaine addiction and potential strategies for developing effective treatments.

'2-faced' particles act like tiny submarines

Scientists at North Carolina State University have developed Janus particles, microscopic spheres with different material properties on either side, which can move and respond to changes in their environment. The phenomenon, called induced-charge electrophoresis, has potential applications in microactuators, sensors, and drug delivery.

Exeter scientists pour cold water on EU bird policy

Researchers from the University of Exeter argue that EU conservation policy has failed to protect endangered birds due to flawed data and lack of monitoring. The study's findings challenge previous claims that EU policy had a positive impact on bird conservation, highlighting the need for systematic evaluation of conservation policies.

Race, insurance status affect access to transplantation and kidney disease treatment

Two studies suggest that universal access to healthcare can reduce racial and ethnic barriers to treatment for kidney disease. Minority patients and those on Medicare or with less education had longer dialysis times before being wait-listed, highlighting the need for improved insurance coverage.
