Field-effect transistors (FETs) are transistors in which the resistance of most of the electrical current can be controlled by a transverse electric field. Over the past decade or so, these devices have proved to be very valuable solutions for controlling the flow of current in semiconductors.

To further develop FETs, electronics engineers worldwide have recently been trying to reduce their size. While these down-scaling efforts have been found to increase the device’s speed and lower the power consumption, they are also associated with short-channel effects (i.e., unfavorable effects that occur when an FET’s channel length is approximately equal to the space charge regions of source and drain junctions within its substrate).

These undesirable effects, which include barrier lowering and velocity saturation, could be suppressed by using 2D semiconductor channels with high carrier mobilities and ultrathin high–k dielectrics (i.e., materials with high dielectric constants). Integrating 2D semiconductors with dielectrics with similar oxide thicknesses has been found to be highly challenging.

Harnessing The Power Of Science & Innovation For All — Dr. Anna Laura Ross, Ph.D., Unit Head for Emerging Technologies, Research Prioritization and Support, Science Division, WHO.


Dr. Anna Laura Ross, Ph.D. is the Unit Head for Emerging Technologies, Research Prioritization and Support, in the World Health Organization (WHO) Science Division (https://www.who.int/our-work/science-division), located in Geneva, as well as the Head of the WHO Science Council Secretariat.

Previously at WHO, Dr Ross served as Strategy Technical Manager at Unitaid, their global health initiative that works with partners to bring about innovations to prevent, diagnose and treat major diseases in low-and middle-income countries, with an emphasis on tuberculosis, malaria, and HIV/AIDS and its deadly co-infections, providing strategic and technical support for Unitaid’s strategy, and working to identify the priorities areas for intervention to accelerate innovation for global health.

Dr. Ross has over fifteen years of experience in global health. Her areas of interest are in the field of HIV biomedical research, scientific program coordination, implementation research, and global health policy.

Prior to joining WHO, Dr. Ross served as Head of International Affairs and Scientific Relations at the National Agency for Research on AIDS and Viral Hepatitis (ANRS) in Paris, France.

The new service will provide 350 Mbps internet, even while taking off and landing.

SpaceX just announced its new Starlink Aviation service, which will allow high-speed in-flight internet that will allow users to make voice calls and stream videogames, according to the company.

The new service promises speeds of up to 350 Mbps for airliners and is aimed mainly at private jet contractors. Earlier this year, SpaceX also announced a partnership with Hawaiian Airlines to bring free WiFi to its flights starting early next year.

SpaceX recently announced Starlink RV and Starlink Maritime. It’s now taken the logical next step, expanding its Starlink service into the skies.

“Approximately 200,000 times thinner than human hair.”

New energy-efficient devices are made possible by the thinnest ferroelectric material ever created, thanks to the University of California Berkeley and Argonne National Laboratory.

As a result of this development, intriguing material behavior at small scales could reduce energy demands for computing, revealed ANL.

“We adapted an idea, developed for experiments to prove the existence of quantum gravity.”

According to Trinity College Dublin scientists, our brains could use quantum computation after applying an idea created to prove the existence of quantum gravity to investigate the human brain and its workings.

As stated, the correlation between the measured brain functions and conscious awareness and short-term memory function suggests that quantum processes are also a part of cognitive and conscious brain functioning.

Published in the Journal of Physics Communications on October 7, the study could provide information about consciousness, which is still a mystery for scientists.

Vintage lovers, unite.

Jason Scott, a tech activist has launched a new website named Discmaster, which enables you to find any file among 91.7 million vintage computer files taken from Archive.org.

“The value proposition is the value proposition of any freely accessible research database,” stated Jason Scott in an interview with Ars Technica.

As you can imagine, the website works best with browsers like Google Chrome, Safari, Firefox, Brave, and Edge while it’d be funny to expect some good results with Internet Explorer 1.0 and 2.0.

The street-legal eVTOL costs only $300k.

A California-based sustainable electric transportation company unveiled the prototype of a flying car, according to a company release. The Alef “Model A,” the only flying automobile with street-legal driving and vertical takeoff abilities, is presented by Alef Aeronautics, a cutting-edge technology company developing alternative transportation solutions for soaring traffic patterns.

Alef uses innovative technology to elevate the vehicle securely above regular traffic, enabling quicker, simpler travel, and reducing the load of urban congestion.
