Simulating blood flow dynamics for improved nanoparticle drug delivery

Simulating blood flow dynamics for improved nanoparticle drug delivery

Despite gaining a bad rap in mainstream media in recent years, nanoparticles have been successfully used for decades in targeted drug delivery systems. Drug molecules can be encapsulated within biodegradable nanoparticles to be delivered to specific cells or diseased tissues. However, blood flow dynamics can significantly affect the nanoparticle's ability to bind at the target site and stay adhered long enough for the drug to be released.

New class of Mars quakes reveals daily meteorite strikes

New class of Mars quakes reveals daily meteorite strikes

An international team of researchers, co-led by ETH Zurich and Imperial College London, has derived the first estimate of global meteorite impacts on Mars using seismic data. Their findings indicate that between 280 to 360 meteorites strike the planet each year, forming impact craters greater than 8 meters (about 26 feet) across.

Engineered biocatalyst for making 'drop-in' biofuels

Engineered biocatalyst for making 'drop-in' biofuels

Researchers at the Department of Inorganic and Physical Chemistry (IPC), Indian Institute of Science (IISc), have developed an enzymatic platform that can efficiently transform naturally abundant and inexpensive fatty acids to valuable hydrocarbons called 1-alkenes, which are promising biofuels.

Climate change to shift tropical rains northward, suggests computer modeling

Climate change to shift tropical rains northward, suggests computer modeling

A study led by a UC Riverside atmospheric scientist predicts that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator.

Researcher discovers 1 in 5 bacteria can break down plastic

Researcher discovers 1 in 5 bacteria can break down plastic

Leiden Ph.D. candidate Jo-Anne Verschoor discovered that nearly 20% of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. "Bacteria are just like people," says Verschoor. Her research was published in the journal Communications Biology.

Researchers develop novel atom-thin material heat test

Researchers develop novel atom-thin material heat test

Advanced materials, including two-dimensional or "atomically thin" materials just a few atoms thick, are essential for the future of microelectronics technology. Now a team at Los Alamos National Laboratory has developed a way to directly measure such materials' thermal expansion coefficient, the rate at which the material expands as it heats.

Biodegradable electronics may advance with ability to control dissolve rate

Biodegradable electronics may advance with ability to control dissolve rate

Biodegradable electronics allow for medical devices—such as drug delivery systems, pacemakers or neural implants—to safely degrade into materials that are absorbed by the body after they are no longer needed. But if the water-soluble devices degrade too quickly, they cannot accomplish their purpose.
