New vibration sensor detects buried objects from moving vehicle

Researchers will report a new laser-based sensor that effectively detects buried objects even while the detector is in motion. This new device offers a significant improvement over existing technologies, which cannot be operated on the go and lose accuracy in the presence of external sources of sound or vibration.

How microtubules branch in new directions, a first look in animals

Cell biologists say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells.

How IL-6 allows the immune response to develop for a key cell, the T follicular helper

A preclinical study shows how the interplay of two interleukin signaling proteins, IL-6 and IL-2, affects the development of T follicular helper cells and germinal centers. This interplay may either maintain or disrupt the balancing act of the immune system between attacking infections and benign surveillance of the body's own cells. Thus, the research may help guide future disease treatment for autoimmune diseases like lupus.

Paramagnetic spins take electrons for a ride, produce electricity from heat

Local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material — where spins weren't thought to correlate long enough to do so. This effect, which the researchers call 'paramagnon drag thermopower,' converts a temperature difference into an electrical voltage.

Team discovers polymorph selection during crystal growth can be thermodynamically driven

Scientists provide solid calculation to demonstrate the structural transformation in colloidal crystallization can be entirely thermodynamic, in contrast to the kinetic argument, from both theoretical and computational perspectives.

Therapeutic strategies for pregnant women with lupus

A highly gender-biased disease, lupus afflicts females some nine times more than males. Because of the disease's unpredictable turns and debilitating flares — the risks of which are elevated in postpartum women — females with the disease are often advised to avoid pregnancy altogether.

Groovy! These grooved patterns better mitigate shock waves

Engineers have discovered a method that could make materials more resilient against massive shocks such as earthquakes or explosions. They found that cutting small grooves in obstacle materials diminished the impacts of what's called the reflected shock wave–once the initial wave has hit the spiral of obstacles and bounced back.

Focus points to reduce opioid overdose deaths identified

A new study identifies specific locations where medication and harm reduction services for people with opioid use disorder should be available in order to have the greatest impact on reducing opioid overdose deaths. The data show that more than half of those who died of an opioid overdose in Massachusetts encountered the health care, public health and/or criminal justice systems within the 12 months prior to their fatal overdose.
