US scientists recreate nuclear fusion in lab, achieve higher yields

Published

on

Scientists in the US achieved greater energy after conducting nuclear fusion, as they were also behind a breakthrough of a historic nuclear fusion carried out in December last year, reported AFP Monday.

The world was amazed in December as the Lawrence Livermore National Laboratory announced it had carried out an experimental nuclear reaction that put out more energy than was put into it — a holy grail of science in the quest for unlimited — clean power to bring an end to the use of fossil fuels.

“We can confirm the experiment produced a higher yield than the December 2022 experiment,” public information officer Paul Rhien said Monday in a statement, without providing further details.

He added: “The California lab planned to report the results at upcoming scientific conferences and in peer-reviewed publications.”

The nuclear fusion was first reported by the Financial Times.

Nuclear fusion is regarded as a clean, abundant, and safe source of energy that could eventually allow humans to ditch coal, crude oil, natural gas, and other hydrocarbons that are behind the global climate crisis.

However, it is a long journey before fusion is viable on an industrial scale, providing power to residences and commercial spaces.

Nuclear power plants around the world currently use fission — the splitting of a heavy atom’s nucleus — to produce energy.

Fusion on the other hand combines two light hydrogen atoms to form one heavier helium atom, releasing a large amount of energy in the process.

On Earth, nuclear fusion reactions can be provoked by heating hydrogen to extreme temperatures inside specialised devices.

Like fission, fusion is carbon-free during operation, and has additional critical advantages: it poses no risk of nuclear disaster and produces much less radioactive waste.

During December’s experiment, the lab used 192 ultra-powerful lasers to deliver 2.05 megajoules of energy to a tiny capsule smaller than a pea containing isotopes of hydrogen. It produced 3.15 megajoules of fusion energy output.

While the result was a net energy gain, 300 megajoules of energy were needed from the electrical grid to power the lasers.

By

The National Computer Emergency Response Team (CERT) has released a security advisory concerning the increasing utilization of artificial intelligence (AI) chatbots, emphasizing potential hazards related to the exposing of private data.

The recommendation recognizes that AI chatbots, like ChatGPT, have gained significant popularity for personal and professional duties owing to their capacity to improve productivity and engagement. Nonetheless, the CERT cautions that these AI systems frequently retain sensitive information, so posing a danger of data breaches.

Engagements with AI chatbots may encompass sensitive information, such as corporate strategy, personal dialogues, or confidential correspondence, which could be compromised if inadequately safeguarded. The warning emphasizes the necessity for a comprehensive cybersecurity framework to alleviate concerns associated with AI chatbot utilization.

Users are advised against inputting critical information into AI chatbots and are encouraged to deactivate any chat-saving functionalities to mitigate the danger of unwanted data access. The CERT additionally advises performing routine system security checks and employing monitoring tools to identify any anomalous behavior from AI chatbots.

Organizations are urged to adopt rigorous security protocols to safeguard against possible data breaches resulting from AI-driven interactions.

At the opening ceremony of the two-day Pakistan Cyber Security Challenge, which took place at Air University in Islamabad, he was the chief guest.
Showdown challenges, the Ideas Cup, and the Pakistan Crypt Challenge are all part of the Pakistan Cyber Security Challenge, which lasts for two days.

Air Marshal (R) Abdul Moeed Khan, VC of Air University, made a speech praising the cyber security abilities of Pakistani youth, saying that they are among the best in the world and will help the country face cyber threats. A haven for cyber security excellence, he said, Pakistan Cyber Security Challenge 2024. Additionally, he praised the Air University for its innovative and outstanding work in this area.
At the inaugural ceremony of the Pakistan Cyber Security Challenge, Dr. Zia Ul Qayyum, executive director of the Higher Education Commission, also spoke to the crowd. He discussed how HEC has created a welcoming atmosphere and helped facilitate projects such as the Pakistan Cyber Security Challenge.
As part of the inauguration event, an MoU was also signed. Guests and participants were given souvenirs as the opening ceremony came to a close.
