Millimeter wave (mmWave) radio frequencies are widely used in modern cars and autonomous vehicles to enable advanced features such as self-driving and assisted driving. However, the use of these frequencies also exposes these vehicles to potential cyberattacks, which can compromise the safety of passengers and pedestrians. To address this issue, researchers from the lab of

Researchers at Oregon State University and Baylor University have discovered a groundbreaking technique to lower the energy consumption of photonic chips utilized in data centers and supercomputers. The study has been published in the Scientific Reports journal. Data centers can consume up to 50 times more energy per square foot of floor space than a

Cryptocurrency mining has become increasingly popular in recent years, but little attention has been paid to the environmental impact of this activity. Estimates suggest that the global electricity usage for cryptocurrency assets like Bitcoin is between 120 and 240 billion kilowatt-hours per year, which is more than what some countries like Argentina and Australia use

TikTok has filed a lawsuit against the state of Montana to stop the implementation of an overall ban on the video-sharing app. The ban, set to start in 2024, has been deemed unconstitutional by TikTok as it violates the right to free speech protected by the constitution. Montana Governor Supports Ban Montana Governor Greg Gianforte

As the number of computer vulnerabilities and bugs continue to increase, cyber defenders are struggling to track, prioritize and prevent all the threats and attacks. With over 213,800 known “keys” or vulnerabilities in computer systems, and likely many more unknown, it is impossible for any one person or team to manage all the information. The

A new study by the University of Florida has found that limiting the use of ride-hailing apps such as Uber or Lyft can have a negative impact on the transportation ecosystem of a city. The study analyzes how a policy implemented by the city of Shanghai to restrict the use of ride-hailing apps affected the

The Chinese government has warned users of computer equipment that is considered sensitive to stop purchasing products from Micron Technology Inc., the largest memory chipmaker in the United States. The Cyberspace Administration of China has stated that Micron products pose unspecified “serious network security risks” that threaten national security and the country’s information infrastructure. The

Social robots are increasingly being used in educational settings for support. However, the question remains: Does the sound of a social robot affect its performance, particularly when dealing with teams of humans? Teamwork is a crucial factor in human creativity, as it enhances collaboration and new ideas. The University of Southern Denmark’s researchers set out

Toyota has suspended shipments of 56,111 Raize hybrid vehicles produced by Daihatsu Motor Co. and 22,329 Daihatsu Rocky vehicles sold in Japan. The suspension comes after Daihatsu revealed that there had been improper crash tests for these models. The company used results for a pole used to measure impact on the left side for the

The G7 leaders have announced that they will launch discussions on the responsible use of generative artificial intelligence. A working group will be set up to tackle issues from copyright to disinformation. The group will be organized in cooperation with the OECD group of developed countries and the Global Partnership on Artificial Intelligence (GPAI). The

Generative AI has become increasingly popular in recent years, but there is a question that is often overlooked: who can afford it? OpenAI, for example, spent around $540 million last year developing ChatGPT and estimates that it needs $100 billion to achieve its goals. “We’re going to be the most capital-intensive startup in Silicon Valley

The United States President Joe Biden’s ambitious plan to reduce greenhouse gas emissions is facing an unexpected challenge: permitting bottlenecks. If the president cannot streamline the permitting process for power plants, transmission lines, and other projects, the country is unlikely to have the infrastructure needed for a future powered by carbon-free electricity. For example, John

WestJet, the second-largest airline in Canada, has announced that it reached a tentative agreement with its pilots union, Air Line Pilots Association, Int’l (ALPA), one day after canceling nearly 100 flights in anticipation of a strike. The union had informed WestJet on Monday that 1,800 pilots would stop work starting early Friday morning if an

Volvo’s factory near Gothenburg is now producing electric trucks, using the same people and equipment as for diesel trucks, but docking an electric module instead of an engine. Electric heavy trucks are being mass-produced in Europe, North America, and China at a faster rate than expected. This is an exciting moment for the industry, according

As the world moves towards renewable energy sources, solar cells are a critical component in this transition. The power conversion efficiency (PCE), or the amount of power captured with a given amount of sunlight, increases the practicality of solar power in a society with high energy demands. The Hurdle of Lower PCE in All-Inorganic Perovskite
