Magnets could be used to produce oxygen in space

Published

  • Magnets attract bubbles of gas to one place where they fuse together. 
  • Where there is lack of gravity, bubbles remain suspended in liquid form.
  • Heavy machinery on international space station uses centrifugal force to force gases out.

Scientists at the University of Warwick have shown how oxygen can be produced in microgravity with the help of magnets.

The magnets attract bubbles of gas to one place where they fuse together. This can replace the heavy machinery that is used to harvest the gas in the low gravity of space.

There is no natural buoyancy in space. This is the primary problem that the recent magnet experiments solve.

On Earth, gas bubbles from liquid naturally rise to the top, but where there is a lack of gravity, bubbles remain suspended in the liquid form.

Heavy machinery on the international space station uses centrifugal force to force the gases out.

These machines need a lot of maintenance and are quite heavy.

A NASA study showed that existing systems were not feasible to carry on long-term missions like trips to Mars and other planets.

To solve the problem, at the special drop tower facility at the Center for Applied Space Technology and Microgravity in Germany, experts studied how magnets could be used to separate gas from liquid.

Different types of liquids were tested. The study concluded that a simple neodymium magnet could be enough to pull out gas in microgravity.

The study was published in a Nature-affiliated journal, NPJ Microgravity.

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.
