Researchers in Southampton and San Francisco have developed the first compact 3D LiDAR imaging system that can match and exceed the performance and accuracy of most advanced, mechanical systems currently used.

3D LiDAR can provide accurate imaging and mapping for many applications; it is the “eyes” for autonomous cars and is used in facial recognition software and by autonomous robots and drones. Accurate imaging is essential for machines to map and interact with the physical world but the size and costs of the technology currently needed has limited LIDAR’s use in commercial applications.

Now a team of researchers from Pointcloud Inc in San Francisco and the University of Southampton...

Study shows super-Earths are not leftovers of mini-Neptunes, challenging our understanding of planetary formation. Mini-Neptunes and super-Earths up to four times the size of our own are the most common exoplanets orbiting stars beyond our solar system. Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown away. In a new study published in The Astrophysical Journal, astronomers from McGill University show that some of these exoplanets never had gaseous atmospheres to begin with, shedding new light on their mysterious origins.

From observations, we know about 30 to 50 percent of host stars have one or the other, and the...

HOUSTON, TX – JUNE 30: (EDITORIAL USE ONLY) Medical staff wearing full PPE wrap a deceased patient with bed sheets and a body bag in the Covid-19 intensive care unit at the United Memorial Medical Center on June 30, 2020 in Houston, Texas. Covid-19 cases and hospitalizations have spiked since Texas reopened, pushing intensive-care wards to full capacity and sparking concerns about a surge in fatalities as the virus spreads.

Algorithm using echocardiogram videos of the heart outperforms other predictors of mortality. Researchers at Geisinger have found that a computer algorithm developed using echocardiogram videos of the heart can predict mortality within a year.

The algorithm – an example of what is known as machine learning, or artificial...

STINGing Tumors with Nanoparticles

A new nanoparticle-based drug can boost the body’s innate immune system and make it more effective at fighting off tumors, researchers at UT Southwestern have shown. Their study, published in Nature Biomedical Engineering, is the first to successfully target the immune molecule STING with nanoparticles about one millionth the size of a soccer ball that can switch on/off immune activity in response to their physiological environment.

“Activating STING by these nanoparticles is like exerting perpetual pressure on the accelerator to ramp up the natural innate immune response to a tumor,” says...
