Tiny sensors offer new hope for faster bone injury recovery

Posted by in categories: biotech/medical, electronics

Tiny implantable sensors are helping University of Oregon researchers optimize the process of recovery from severe bone injuries.

Scientists at the UO’s Phil and Penny Knight Campus for Accelerating Scientific Impact have developed miniature that transmit about what’s happening at an injury site. In a new study, they use the technology to show that a resistance-training rehabilitation program can significantly improve femur injuries in rats in just eight weeks.

The sensors provide a window into the mechanical properties of the , giving scientists detailed ongoing data about the process of . If someday applied in humans, these sensors could allow doctors to better tailor a rehabilitation program to an individual patient, monitoring their progress and adjusting the exercises along the way.

Shaking felt across Central California following magnitude 5.5 earthquake in Nevada

Posted by in categories: computing, electronics

SACRAMENTO — A magnitude 5.5 earthquake that struck in a remote area of Nevada on Monday afternoon sent shaking throughout Central California, including the Sacramento area.

In Sacramento, one person saw ornaments on a Christmas tree sway, as did some blinds for less than a minute. Water sloshed in a swimming pool, another person said. In Davis, a computer swayed for just a few seconds and a desk chair was jolted, while a young man reported feeling his bed sway and an unnerved poodle sought comfort.

In Reno, about 50 miles northwest of the quake’s epicenter, someone at KTVN-TV captured a video of the star on the newsroom’s Christmas tree still quivering — barely — as staffers scrambled to cover the earthquake. One person could be heard saying they hadn’t felt anything.

Antiferromagnetic spin-torque diode effect in a kagome Weyl semimetal

Posted by in categories: computing, electronics

In a Mn3Sn/W epitaxial bilayer, spin–orbit torque induces the coherent rotation of spins, which can couple to microwave currents. Unlike in ferromagnets, the resulting conversion of AC current to DC voltage remains robust at higher frequencies, which may facilitate the development of high-speed electronic devices.

Quantum Leap for MRI: Atomic Sensors Unlock New Imaging Potential

Posted by in categories: biotech/medical, electronics

Magnetic resonance imaging (MRI) is a fundamental tool in modern medicine, offering detailed views of internal organs and tissues. These large, tube-shaped MRI machines, commonly seen in hospitals, utilize powerful magnets to analyze and visualize the density of water and fat molecules within the body.

In addition to these molecules, other substances like metabolites can also be mapped, but their concentrations are often too low to produce clear images. To overcome this limitation, a technique known as hyperpolarization is employed to enhance the magnetic resonance signal of these substances, making them more visible during MRI scans.

Hyperpolarization involves preparing a substance outside the body in a state where its magnetization—key to creating MRI images—is near its maximum. This process can boost the signal by thousands of times compared to its natural state. Once hyperpolarized, the substance is injected into the patient and transported to the target organ or tissue. However, before this can happen, it is crucial to confirm that the substance is adequately hyperpolarized through rigorous quality control processes.
