The recent lawsuit filed by the United States accused TikTok of violating children’s privacy by collecting data about them without their parents’ permission while using the app. The Department of Justice and Federal Trade Commission (FTC) collaborated in a civil suit alleging that TikTok broke the Children’s Online Privacy Protection Act (COPPA). Violation of COPPA

Predicting tipping points for critical Earth system components such as the Atlantic Meridional Overturning Circulation (AMOC), polar ice sheets, and tropical rainforests is a daunting task due to significant uncertainties. A recent study published in Science Advances highlights the challenges in accurately forecasting when these tipping events might occur in response to human-caused global warming.
For decades, physicists have been puzzled by the fundamental question of why the universe is filled with matter while containing so little antimatter. According to the standard model of particle physics, after the Big Bang occurred over 13 billion years ago, matter and antimatter were continuously generated in equal amounts and subsequently annihilated upon collision,
Gas separation is a crucial process in both manufacturing and research, but traditional methods come with a hefty environmental cost. The current approaches account for a significant 15% of U.S. energy consumption and result in the production of millions of tons of carbon emissions. Clearly, there is a pressing need for more efficient and sustainable
In a groundbreaking study published in Nano-Micro Letters, a team of researchers has developed high-density three-dimensional carbon tube nanoarray electrodes that have the potential to revolutionize the world of line-filtering capacitors. These miniaturized filter devices offer high-performance capabilities, addressing the limitations of traditional aluminum electrolytic capacitors (AECs) and providing a promising alternative in the realm
Throughout history, the perception of stars as fixed and unchanging has been shattered by the appearance of unpredictable “guest stars.” These celestial events, such as the one witnessed on July 4, 1054, challenge ancient beliefs and captivate astronomers worldwide. Unlike the steady glow of familiar stars, guest stars emerge suddenly, brighten the sky for a
The medical world has been buzzing with excitement over the recent breakthrough in artificial heart technology. A 58-year-old man in the United States made history by becoming the first person in the world to receive a temporary, titanium blood-pumper designed by BiVACOR. This innovative device is a total artificial heart (TAH) that aims to replace
Innovations in water treatment technology are constantly evolving, with engineers and researchers striving to find efficient and sustainable solutions to address the presence of harmful chemicals in our water supply. One such groundbreaking development comes from the University of Bath, where a team of researchers has devised a method using 3D printing to remove ‘forever
The detection of gravitational waves has opened up a new realm of possibilities in the field of astrophysics. When black holes collide, the resulting ripples in space-time provide crucial insights into the structure of our universe. The observation of these waves, first predicted by Einstein a century ago, marks a significant milestone in our quest
Studying ancient ocean temperatures is crucial for understanding past climate conditions and predicting future climate trends. One common method used to reconstruct these temperatures is by analyzing the ratio of different oxygen isotopes in calcium carbonate remains of fossils. However, this approach is not without its challenges, as biological processes known as “vital effects” can
Artificial intelligence (AI) technology has been rapidly advancing in recent years, with applications such as generative AI pushing the scalability of existing digital hardware to its limits. As a result, there is a growing interest in analog hardware specialized for AI computation. A recent study, published in Science Advances, has shed light on the potential
Interbasin water transfers play a crucial role in transporting water across vast geographical areas in the U.S. West. The recent research published in the journal Nature Water sheds light on the energy-related greenhouse gas emissions associated with these projects, with two key projects in Arizona and California contributing to a majority of the emissions. The
