Thursday, scientists at the University of California San Diego reported in the journal Science of the Total Environment that a type of polyurethane already used in biodegradable land-based products can also break down when immersed in seawater. This polyurethane is already used as a substitute for plastic in foams and shoes.

The research team performed their experiments at the Ellen Browning Scripps Memorial Pier and Experimental Aquarium. They cut the polyurethane into cubes similar in size and shape to those naturally formed by EVA plastics. They wrote that several types of marine bacteria and fungi stick to the polyurethane and break it down to its component chemicals, which they then consume for food. The polyurethane microbes had already made detectable progress when the scientists checked the samples after four weeks in the water.

“Improper disposal of plastic in the ocean breaks down into microplastics and has become an enormous environmental problem,” said study co-author Stephen Mayfield, director of the California Center for Algae Biotechnology. “We’ve shown that it’s absolutely possible to make high performance plastic products that also can degrade in the ocean.”

Humans deposit roughly 8 billion kg of plastic in the ocean each year, where it can be mistaken for food by marine organisms. Natural forces break the plastic into the small pieces that we call microplastic, while larger chunks forms near-islands, such as the Great Pacific Garbage Patch. By mass, about half the patch is commercial fishing waste, such as discarded nets, but reducing the amount of post-consumer plastic in the ocean would still make a considerable dent in the planet’s plastic problem.

This type of polyurethane is can be used to make flip-flops and parts of other shoes, which make up a considerable portion of the world’s plastic waste.

By a narrow vote late in the evening on December 21st, 2005 the US Senate blocked opening the nation’s oil reserve in National Wildlife Refuge in Alaska . This vote delivers a victory to environmentalists and denies the Bush administration their top energy priority. Senator Ted Stevens (R-Alaska) attached the drilling plan to a measure to fund ongoing military operations in Iraq and Afghanistan. However, the Senate late last night agreed to pass the defense bill, without the drilling provision.

Two key Republicans, Lincoln D Chafee (R-R.I.) and Mike DeWine (R-Ohio), joined Democrats in opposing the drilling. Senator Lieberman (D-Conn) said yesterday that Stevens was to blame for holding up money for the military. By including the drilling measure in the defense spending bill, it was hoped to twist the senators’ arms into voting for both provisions together in the scramble to finish the important business before the Senate’s Christmas break.

Studies done on germs and bacteria performed by researchers at the University of Florida show that a dirty kitchen sponge can be cleaned and “sterilized” by microwaving it for 2 minutes, but researchers warn to wet the sponge first.

“People often put their sponges and scrubbers in the dishwasher, but if they really want to decontaminate them and not just clean them, they should use the microwave,” said the professor who was in charge of the study that discovered the results, Gabriel Bitton.

“Basically what we find is that we could knock out most bacteria in two minutes. The microwave is a very powerful and an inexpensive tool for sterilization,” added Bitton.

The sponges that researchers studied, were placed in “raw wastewater” and then put into a microwave to be “zapped,” according to Bitton. The wastewater was a “witch’s brew of fecal bacteria, viruses, protozoan parasites and bacterial spores, including Bacillus cereus spores,” said Bitton.

Researchers say that at least 99% of the bacteria, viruses, spores and parasites in kitchen spongees can be destroyed or “inactivated” by simply microwaving the wet sponge, on the highest power, for two minutes.

One of the world’s largest media conglomerates Sony has announced that its net profits have plummeted by 95% in the months of October and December quarter. Sony also stated that its revenue fell too by 25%, from $31.64 billion to $23.78 billion.

Sony’s most popular products: TV, digital cameras, mobile phones, and computers were hit by the crisis with a loss of $175.9 million as sales drop. This is a big difference to Sony’s last year profit of $2.2 billion.

The Chief Financial Officer Nobuyuki Oneda said, “From the second half of September last year, there has been a sudden deterioration in the economy, and with the effects of foreign exchange it has had severe consequences on our business.”

Analyst David Gibson stated that its TV’s sales really dragged them down this quarter.

The 10.10 version of Ubuntu (codename Maverick Merkaat), a free operative system is to be released in the next few days. French Wikinews contributor Savant-fou (Baptiste) has interviewed Fabrice (fabrice_sp on Ubuntu), an Ubuntu’s MOTU (Master Of The Universe), member of the development team of the operative system.

Ubuntu is a computer operating system, based on Debian, which is created collaboratively by thousands of people. There are three official Ubuntu versions: Ubuntu Desktop Edition (for desktop and laptop PCs); Ubuntu Netbook Edition (for netbooks); and Ubuntu Server Edition (for use in servers).

Access to search engine Google has been limited and most of Google’s online services cannot be accessed in Turkey. The access limitation happened due to the blocking of an IP set that belongs to Google. These IP addresses were shared between YouTube and other Google services.

The Turkish news site Hürriyet Daily News reports that Turkey’s Telecommunications Communication Presidency (TCP) (a government agency that manages Turkish ISPs) indefinitely shut off access to several Google services. The shut-off came after the banning of YouTube for alleged insults against Turkish Republic founder Mustafa Kemal Atatürk. TCP released an official statement Friday, saying it had blocked access to some Google IP addresses “because of legal reasons”. Under Turkish law, it is an offence to “insult Turkishness.”

Softpedia states that the limited access to Google could be a result of the government trying to block specific DNS addresses that relate to Google, as part of its ongoing attempts to block YouTube. Since Google services share common software and IP addresses, the search engine itself suffers from access restrictions. Turkish citizens are concerned that this move of the governmental agency was another step towards a complete ban on Google, as exists in China.

Several Internet sites have been banned in Turkey in recent years, and although some of them were subsequently unbanned, most of them remain inaccessible. Engelli Web, a website listing banned sites reports that currently YouTube (since May 2008), Last.fm (since June 26, 2009), and Spanish newspaper El Mundo (since May 14, 2010) are among the banned sites in Turkey. MySpace and WordPress were also among banned sites for a period of time. Websites will be blocked following a court decision or if TCP decides to block on its behalf.

RetweetToday reports that Turkish citizens on Twitter have also reported access problems. Comments about the blockage are being shared using hashtags such as TurkeyCensorGoogle and TurkeyGoogleBan, as well as NoGoogleNoWeb.

On Tuesday, US-based software company Red Hat announced their plans to shift their focus away from CentOS in favour of CentOS Stream.

In the blog post Chris Wright, the Chief Technological Officer of Red Hat said Red Hat had informed the CentOS governing board that Red Hat was “shifting our investment fully from CentOS Linux to CentOS Stream”. At least five of the nine CentOS Governing Board listed on the project are Red Hat employees.

Started in 2004, CentOS has been a free-of-cost free/libre open source software which provided binary-code compatibility with Red Hat Enterprise Linux (RHEL) — Red Hat’s GNU General Public Licensed paid operating system. CentOS was absorbed into Red Hat in 2014, with Red Hat gaining the trademark rights of “CentOS”.

Red Hat also sponsors the Fedora operating system. Red Hat even gives the software engineering interns laptops with Fedora on it. Till now, software development took place on Fedora, which was later adopted in RHEL, which the Red Hat maintained and provided support for, for those customers who had RHEL subscription. CentOS would then follow RHEL to provide the same features free of cost, but without the support.

Stream was announced in September 2019, just two months after Red Hat was acquired by IBM. CentOS Stream’s development cycle had new features added to it before the features became a part of RHEL. Stream receives more frequent updates, however, it does not follow RHEL’s release cycle.

With CentOS Stream, developments from the community and the Red Hat emplyees would take place beforehand on both Fedora, and Stream as a rolling release, before those features are absorbed into RHEL. CentOS followed the release cycle of RHEL and therefore it was a stable distribution. Features available in CentOS were tried and tested by Fedora, and then RHEL maintainers. Stream, on the other hand, has features added to it before those features become a part of RHEL. That implies Stream would be ahead of RHEL’s development, containing new features which are not yet tried and tested by RHEL developers, and not be binary code-compatible with RHEL.

Writing “The future of CentOS Linux is CentOS Stream”, Wright further wrote in the announcement, CentOS Stream “provides a platform for rapid innovation at the community level but with a stable enough base to understand production dynamics.” Wright also said, “CentOS Stream isn’t a replacement for CentOS Linux; rather, it’s a natural, inevitable next step intended to fulfill the project’s goal of furthering enterprise Linux innovation.”

Since the announcement was made, many people expressed their anger on Internet Relay Chat (IRC), Reddit and CentOS project’s mailing list. CentOS 8’s End of Life (EOL) has been moved up from May 2029 to December 31, 2021, while CentOS 7 is expected to receive maintenance updates through June 2024, outliving CentOS 8.

Gregory Kurtzer, who had started the CentOS project, announced a new operating system, Rocky Linux. Rocky Linux describes itself as “a community enterprise Operating System designed to be 100% bug-for-bug compatible with Enterprise Linux”. The project said “Rocky Linux aims to function as a downstream build as CentOS had done previously, building releases after they have been added to the upstream vendor, not before.” The project maintainers have not decided a date for when the operating system will be released.

Kurtzer explained the reason to call the OS as Rocky Linux: “Thinking back to early CentOS days… My cofounder was Rocky McGaugh. He is no longer with us, so as a H/T [hat tip] to him, who never got to see the success that CentOS came to be, I introduce to you…Rocky Linux”.

Wikinews reached out to the members of the CentOS project, Pablo Greco and Rich Bowen, to discuss this move, its implications as well as the future of CentOS. Greco is a maintainer of armhfp (32-bit processors) and is a part of the CentOS’ quality assurance team. Bowen — who unlike Greco, works for Red Hat — is the community manager of the CentOS project.

Singapore police arrested British author and journalist Alan Shadrake one day after the launch of his book about the country’s use of the death penalty.

Shadrake, 75, was arrested on Sunday morning at a hotel in Singapore and taken into custody by police on charges of criminal defamation, in response to a complaint lodged by the city-state’s Media Development Authority (MDA) over the contents of his new book, Once a Jolly Hangman: Singapore Justice in the Dock. Separately, the Attorney-General served Shadrake with an application for an order of committal for contempt of court, accusing him of “cast[ing] doubt on the impartiality, integrity, and independence” of Singapore’s courts through his book.

Shadrake’s latest book discusses alleged “double standards” in the country’s application of the death penalty, and contains interviews with local human rights activists, lawyers, and former police officers, including retired Changi Prison executioner Darshan Singh; Singh later claimed that he had been “tricked” into the interview. In earlier media comments, Shadrake stated that he expected “trouble” but no concrete action from authorities over his book, lest they draw even more attention to its claims. Retailers took his book off shelves after inquiries by the MDA; a spokesman for the MDA stated that the book was not banned, but suggested that booksellers “seek legal advice to ensure that the books they sell do not contravene Singapore laws”.

Shadrake has written for a variety of newspapers, including The Daily Telegraph of London as well as the New Straits Times of neighbouring Malaysia. His previous book, The Yellow Pimpernels, told the tale of various attempts to escape from East Germany over the Berlin Wall. If convicted, he faces a two-year imprisonment and a fine.
