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.

In order to provide children with technical education and training, Sindh Governor Kamran Tessori has made the decision to set up IT classes for 50,000 children.

The governor urged the youth to play a vital part in the nation’s growth during a ceremony held here on Thursday.

“Pakistan has an abundance of skill. We will have to play our role in the development of the country. We will have to work to improve our economy,” the governor said.

He urged the overseas Pakistanis to invest in Pakistan and play their role in making the country prosperous.

Addressing the youth of the country, Kamran Tessori said, “Pakistan should be our priority. We need to do everything for Pakistan.

Cybersecurity firm reports exposure of sensitive DeepSeek data on the internet.

The New York-based cybersecurity firm Wiz has discovered a cache of sensitive data from the Chinese artificial intelligence business DeepSeek that was mistakenly exposed to the public internet.

In a blog post released on Wednesday, Wiz reported that examinations of DeepSeek’s infrastructure revealed that the company had inadvertently exposed over a million lines of unencrypted data. The materials were digital software keys and chat logs that seemingly documented prompts transmitted from consumers to the company’s complimentary AI assistant.

The chief technical officer of Wiz stated that DeepSeek promptly safeguarded the data following the notice from his organisation.

“It was removed in under an hour,” stated Ami Luttwak. “However, this was exceedingly easy to locate, leading us to believe we are not the sole discoverers.”

DeepSeek did not promptly respond to a request for comment.

DeepSeek’s rapid success after the introduction of its AI helper has exhilarated China and incited concern in America. The Chinese company’s evident capacity to rival OpenAI’s skills at a significantly reduced cost has raised concerns regarding the viability of the business models and profit margins of U.S. AI behemoths like Nvidia and Microsoft.

By Monday, it surpassed the U.S. competitor ChatGPT in downloads from Apple’s App Store, prompting a worldwide decline in technology stocks.

WhatsApp launches bulk channel management functionality

Published

By

WhatsApp has initiated testing of a bulk channel administration feature on iOS for select beta users, enabling the simultaneous selection of many channels, hence enhancing the efficiency of managing following channels.

This essential update enables users to perform bulk activities, including muting many channels simultaneously, designating them as read, and altering notifications. If the chosen channels are muted, users will now have the option to activate notifications. Users can swiftly silence unmuted channels in one action.

Additionally, this feature enables users to unfollow many channels simultaneously, thereby optimizing the process of decluttering their channel list. This change is particularly beneficial for users that oversee numerous subscriptions, as reported by WABetaInfo.

Previously, users were required to manage each channel individually, rendering tasks such as muting or designating channels as read laborious and time-consuming.

The functionality provides enhanced flexibility and control over channel subscriptions, enabling users to efficiently manage notifications. The solution streamlines laborious operations for consumers who subscribe to numerous channels, hence enhancing their entire experience.

Accessibility
The bulk management feature is presently accessible exclusively to a limited number of beta testers who installed the latest WhatsApp beta for iOS using the TestFlight application. WhatsApp, owned by Meta, plans to expand the feature’s availability to a larger user base in the next weeks.

This update demonstrates WhatsApp’s dedication to enhancing user experience by offering a clear and efficient method for managing channels and notifications.
