Turbulence is notoriously difficult to forecast. UC San Diego researchers have predicted that if a pipe is sufficiently curved, the transition can become discontinuous, with the turbulent fraction undergoing a jump beyond a critical flow velocity.
New research from UC San Diego's Scripps Institution of Oceanography reveals that barrels with halos - previously thought to contain the pesticide DDT - contain caustic alkaline waste.
A team of international scientists is urging caution against five of the most-discussed polar geoengineering ideas, stating they are highly unlikely to help the polar regions and could harm ecosystems, international relations, and reduce our chances of reaching net zero by 2050.
Scientists have carefully studied the effects of space and microgravity on astronauts. One truth is certain: space is brutal on the human body. Muscles atrophy, bones lose mass, limbs stretch and — more unknown — eyesight can degrade in ways not yet fully understood.
UC San Diego researchers at SSCI have discovered that spaceflight accelerates the aging of human hematopoietic stem and progenitor cells (HSPCs), which are vital for blood and immune system health.
Increasing ocean temperatures will erase mangrove restoration gains, according to new research. Scripps Oceanography scientists and colleagues project that by 2100 the world would lose out on 150,000 hectares (370,000 acres) of mangroves and associated ecosystem services worth $28 billion annually.
