Tech
The 5G revolution has begun, and the first lines of phones that can access the next generation of wireless speeds have already hit the shelves. Researchers at The University of Texas at Austin and the University of Lille in France have built a new component that will more efficiently allow access to the highest 5G frequencies in a way that increases devices' battery life and speeds up how quickly we can do things like stream high-definition media.
Owing to a rare genetic mutation, individuals with leukocyte adhesion deficiency type 1 (LAD1) experience a suite of symptoms that trace back to an immune system dysfunction. Many have recurrent bacterial infections and gum disease so serious that they often lose their teeth at an early age.
Ring, Nest, SimpliSafe and eight other manufacturers of internet-connected doorbell and security cameras have been alerted to "systemic design flaws" discovered by Florida Tech computer science student Blake Janes that allows a shared account that appears to have been removed to actually remain in place with continued access to the video feed.

Mental Health Treatment for Front-Line Clinicians During and After COVID-19
MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately lead to new ways of performing certain industrial or medical processes that require separation of tiny suspended materials.
Shake, rattle and roll.
Blobs can wreak havoc in plasma required for fusion reactions. This bubble-like turbulence swells up at the edge of fusion plasmas and drains heat from the edge, limiting the efficiency of fusion reactions in doughnut-shaped fusion facilities called “tokamaks.” Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have now discovered a surprising correlation of the blobs with fluctuations of the magnetic field that confines the plasma fueling fusion reactions in the device core.
New aspect of understanding
In complex surgery, is there a correlation between the volume of services provided per hospital and the quality of treatment results? This is the question addressed in eight commissions on minimum volumes that the Federal Joint Committee (G-BA) awarded to the Institute of Quality and Efficiency in Health Care (IQWiG). The IQWiG report is now available for the fifth intervention to be tested, kidney transplantations.
Based on previously released data and their own investigations, researchers at the St Petersburg University Laboratory of Macroecology and Biogeography of Invertebrates have assessed the diversity of freshwater molluscs in the Circumpolar region of the World. In total, they registered 104 species of these invertebrates living in waters within the Arctic Circle. Their hermaphroditism, their ability to freeze in ice and their 'friendship' with birds have all helped them to enter the Arctic and to survive under its harsh conditions.
Skoltech and MIPT scientists have predicted and then experimentally confirmed the existence of exotic hexagonal thin films of NaCl on a diamond surface. These films may be useful as gate dielectrics for field effect transistors in electric vehicles and telecommunication equipment.
This type of TNBC tumor does not express any of the receptors involved in most breast cancers (estrogen, progesterone and HER2), so the most common treatments, such as the hormone therapy, are not viable in these patients.
Using biologically inspired robotic swarms consisting of large groups of robots that have been programmed to operate cooperatively, much like individuals in an ant or bee colony, scientists from the University of Colorado demonstrate that the locally observed distribution of robots can be correlated to the location of environmental features, such as exits in office-like environments. The study's findings were published in IEEE/CAA Journal of Automatica Sinica.
Researchers in the US and Korea reported the first efficient flexible light-emitting diodes with a two-dimensional titanium carbide MXene as a flexible and transparent electrode. This MXene-based light-emitting diodes (MX-LED) with high efficiency and flexibility have been achieved via precise interface engineering from the synthesis of the material to the application (Advanced Materials,2020, 2000919).
Most people at high risk of overdose in Vancouver's Downtown Eastside who use cannabis do so for pain relief and other therapeutic reasons--and they may be at lower risk of overdosing on opioids as a result, suggests new research published in the peer-reviewed journal PLOS ONE.
Osaka, Japan - Researchers at the Center for Quantum Information and Quantum Biology at Osaka University used trapped ions to demonstrate the spreading of vibrational quanta as part of a quantum random walk. This work relies on their exquisite control of individual ions using lasers, and can lead to new quantum simulations of biological systems.
