Engineered bone marrow could improve transplants

Engineers at the University of California San Diego have developed biomimetic bone tissues that could one day provide new bone marrow for patients needing transplants. Bone marrow transplants are used to treat patients with bone marrow disease. Before a transplant, a patient is first given doses of radiation, sometimes in combination with drugs, to kill off any existing stem cells in the patient's bone marrow.

Strength of hair inspires materials for body armour

Researchers at the University of California San Diego investigate why hair is incredibly strong and resistant to breaking. The findings could lead to the development of new materials for body armor and help cosmetic manufacturers create better hair care products. Hair has a strength to weight ratio comparable to steel. It can be stretched up to one and a half times its original length before breaking.

Laser technology could improve telecommunications and computing

Researchers at the University of California San Diego have demonstrated the world's first laser based on an unconventional wave physics phenomenon called bound states in the continuum. The technology could revolutionise the development of surface lasers, making them more compact and energy-efficient for communications and computing applications. The new BIC lasers could also be developed as high-power lasers for industrial and defense application...

Acoustic waves move fluids at the nanoscale

A team of mechanical engineers at the University of California San Diego has successfully used acoustic waves to move fluids through small channels at the nanoscale. The breakthrough is a first step toward the manufacturing of small, portable devices that could be used for drug discovery and microrobotics applications. The devices could be integrated in a lab on a chip to sort cells, move liquids, manipulate particles and sense other biological c...

Magnetic ink can print self-healing batteries

A team of engineers at the University of California San Diego has developed a magnetic ink that can be used to make self-healing batteries, electrochemical sensors and wearable, textile-based electrical circuits. The key ingredient for the ink is microparticles oriented in a certain configuration by a magnetic field. Because of the way they're oriented, particles on both sides of a tear are magnetically attracted to one another, causing a de...

Metamaterial uses light to control its motion

Researchers have designed a device that uses light to manipulate its mechanical properties. The device, which was fabricated using a plasmomechanical metamaterial, operates through a unique mechanism that couples its optical and mechanical resonances, enabling it to oscillate indefinitely using energy absorbed from light. This work demonstrates a metamaterial-based approach to develop an optically-driven mechanical oscillator.

Catheter lets doctors see inside arteries for first time

Removing plaque from clogged arteries is a common procedure that can save and improve lives. This treatment approach was recently made even safer and more effective with a new, high-tech catheter that allows cardiologists to see inside the arteries for the first time, cutting out only the diseased tissue. Interventional cardiologists at Sulpizio Cardiovascular Center at UC San Diego Health are the first in the region to use this technology.

Nanobowls magnetically deliver drugs to specific organs

Imagine a device that could transport drugs to any diseased site in the body with the help of a small magnet. Researchers at the University of California San Diego have taken a step toward that goal by developing nano-sized vessels, called nanobowls, that could be filled with drug molecules and controlled with magnets for guided delivery to specific tissues and organs, including cancer tissue, small organs such as the pancreas and hard to access ...
