A team of experts from the University of Barcelona and the company Sensofar Tech have designed an innovative technology to obtain three-dimensional images of a study sample quickly, accurately and non-invasively. The work has been published in Nature Communications. The new system is capable of characterizing the three-dimensional topography of an object with a speed and … Read more

Scientists develop new data storage tech to combat data explosion

by

With the development of the internet, social media and cloud computing, the amount of data created worldwide on a daily basis is sky-rocketing. This calls for new technologies that could provide higher storage densities combined with secure long-term data archiving far beyond the capabilities of traditional data storage devices. An international research team led by … Read more

New study suggests betelgeuse’ surface convection mimics rapid rotation

by

Betelgeuse is a well-known red supergiant star in the constellation Orion. Recently it has gained a lot of attention, not only because variations in its brightness led to speculations that an explosion might be imminent, but also because observations indicated that it’s rotating much faster than expected. This latter interpretation is now put into question … Read more

Astronomers map dust distribution in our galaxy with unprecedented detail

by

If you explore the night sky it won’t be long before you realize there is a lot of dust and gas up there. The interstellar dust between the stars accounts for 1% of the mass of the interstellar medium but reflects 30% of the starlight in infrared wavelengths. The dust plays a key role in … Read more

Breakthrough resolution in electron microscopy achieved without expensive aberration correction

by

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution.. The field of microscopy is in the middle of a great revolution. Since the 1800s and the invention of the compound light microscope, there have only been a … Read more

Patterned low-intensity low-frequency ultrasound (LILFUS) shows promise for precise neuromodulation and enhanced brain plasticity

by

The human brain’s adaptability to internal and external changes, known as neural plasticity, forms the foundation for understanding cognitive functions like memory and learning, as well as various neurological disorders. New research conducted by a team led by Dr. Park Joo Min of the Center for Cognition and Sociality within the Institute for Basic Science … Read more
