In findings published last month in the journal Current Biology, neuroscientists from the Netherlands Institute for Neuroscience examined harm aversion in laboratory rats for conspecifics — rats not wanting to hurt other members of the same species — and reported which region of the brain was crucial for it. Wikinews caught up with Dr Christian Keysers and Dr Valeria Gazzola, two of the authors who contributed to the paper.

For the experiment, the rats were put in a container with two levers. The rats were trained to develop a preference for one of the two levers: each delivering one pellet of sucrose. One of the two levers was harder to press.

After developing a preference, the preferred lever was wired to deliver a shock to another rat in a neighbouring compartment, while delivering a single pellet of sucrose. The study showed the actor rat, which pressed the lever tend to switch the lever to avoid shocking the other rat. The rat receiving the shock was called a victim rat.

Aversion of harm to fellow rats was reported to be equal in both male and female rats. If the actor rats were previously exposed to the shocks, their degree of harm aversion for others was heightened, the study revealed.

The investigation reported the rats avoided pressing the preferred lever to shock another rat, even if that lever delivered two sucrose pellets and the no-harm lever delivered only one. However, this was not the case when the rats were given three pellets by the shock lever. Most of the actor rats did not switch when they received three pellets pressing the lever, which also delivered an electric shock. Dr Gazzola called it a “tipping point” and said it was a “cost-benefit” function.

The study also revealed the importance of the anterior cingulate cortex (ACC) region of the rat’s brain for harm aversion. The scientists tested harm aversion for conspecifics in the rodents after deactivating the ACC using muscimol. Muscimol was injected in the rats belonging to the test group, while saline water was injected to rats in the control group. The observations showed without the active ACC due to muscimol, the active rats in the test group were no longer averse to harming the victim rats, but degree of harm aversion did not drop in the control group rats.

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.

A former mailman who proposed to paint the town hall pink, turn the local town square into a nudist pool, and to plant a marijuana field in the local park has been elected to the Reus, Spain town council.

Ariel Santamaria promised to show up to the town’s council meetings dressed up as Elvis Presley if he was elected and kept his word at the town’s first meeting on Thursday.

Before being elected, Santamaria who is a member of the Reus Independent Coordination, had also promised the town’s 100,000 residents that he would install a GPS system at the police department that would allow officers to track people who are smoking marijuana and provide them with a light if they need one.

An unnamed media consultant who works for Santamaria set up a website for his campaign and followed Santamaria wherever he went, dressed as a pirate.

Last month, a study conducted by archæologist Dr. Naomi Martisius and other researchers concluded Neanderthals living in Europe tens of thousands of years ago were more sophisticated than previously thought. The now-extinct species used to carefully select bones from a particular animal species to manufacture their bone tools, the research showed. The research was published on May 8 in Nature’s Scientific Reports journal.

Dr Martisius and her team used five bone tools discovered from Neanderthals’ sites in southwest France for this research. Four of these bone tools were found in a site called Abri Peyrony and the other one was from Pech-de-l’Azé I. These tools were just a few centimetres in size and were about 50 thousand years old, Dr Martisius told Wikinews. Microscopy analysis of these bone tools called lissoirs (smoothers) suggested Neanderthals used these tools for working animal skin to leathers.

The study stated the fauna of the sites were primarily medium-sized ungulates such as reindeer, in one layer nearly 90%. Despite the overabundance of medium-sized ungulates, Neanderthals used ribs of large bovids for making lissoirs. Dr Martisius told Wikinews this was likely due to the physical characteristics of the bovid ribs, which were “thicker” and “stronger” as compared to the “thin and flimsy ribs” of reindeers. In order to check the origins of the bone tools, the researchers used a technology called non-destructive Zooarchæology by Mass Spectrometry (ZooMS).

Instead of damaging the bone artefacts in order to discover its origins, the researchers collected collagen from the plastic containers in which these artefacts were kept. Collagen is a type of protein. These bone artefacts were kept in plastic containers: some were kept for about five years, some for just a few months. During this time, the collagen proteins from bone tools were stuck to the walls of its plastic containers. The collagen samples collected from the walls of the containers are broken into smaller molecules called peptides by using a chemical enzyme called trypsin.

After the trypsin has broken collagen fibres into peptides, it is analysed using a technology called Matrix-assisted laser desorption/ionization (MALDI) Time-of-Flight mass spectrometer (ToF MS). The assisting matrix is a coloured compound. The acidic peptide is combined with the matrix, vapourised, and peptides are released. Some of them are positively-charged particles which travel across a vacuum tube in an electric field. Depending on the weight of the peptides, these molecules reach the end of the vacuum tube at different instances of time, forming a spectrum. These graphs are like unique fingerprints of a species: they are different for different species of animals. Looking at the database of such graphs, taxonomic identifications of the collagen proteins came be made.

All four bone tools from Abri Peyrony gave positive results and showed that the bones were made from large bovids, even though reindeer were more abundant during that time. One of the advantages of using bovid ribs over reindeer’s thin ribs was the bovid ribs would be more resistant to breaking during flexion, Dr Martisius said.

Dr Martisius said such non-destructive ZooMS analysis was previously conducted, but for tools no older than a few centuries. She said such an analysis had never been previously conducted for artefacts so ancient.

Wikinews caught up with Dr Martisius to discuss this research in-depth.

As families fled their homes in the early morning hours on Thursday October 26, there was no warning. The Esperanza Fire southeast of Los Angeles and West of Palm Springs, California, had ballooned under the influence of Santa Ana winds to more than 19,000 acres as of the morning of October 27. No time to get the animals, no time for crates or even a leash. Sadly, owners left behind not only their horses, lamas, donkeys, chickens, rabbits, but also their dogs and cats.

Many of the families who did manage to evacuate their pets found themselves in the parking lot at the Fellowship in the Pass Church Red Cross Shelter where a MuttShack Animal Rescue team caught up with them.

Pam Anderson, Director of the emergency Red Cross shelter said that many people with animals had come and left.

The air was thick with smoke, and ash was raining down on the parking lot where dog owners, not able to take their dogs into the shelter were camping out in pup tents andin their cars.

Those who could afford it checked themselves into pet friendly hotels in nearby towns.

Some were prepared. Jane Garner, a small dog breeder was able to get all her animals out, and had set up her puppy runs alongside her RV in the parking lot. Others were not doing too well, having left home without as much as a leash.

The same scenario played out at the Red Cross shelter at Hemet High School. Animals were being boarded in vans, trailers and cars and small travel crates.

When MuttShack Animal Rescue arrived, a small fracas had sent several dogs off in different directions, running out of the school parking lot down busy streets necessitating an instant rescue response.

The Incident Command for the Esperanza Animals, Ramona Humane Society in San Jacinto welcomed MuttShack‘s offer to help at the shelters.

Ramona Humane Society had recently published a notice in their Newsletter about the newly passed “PETS Act”and warned owners not wait until a major disaster such as an earthquake or fireto prepare. “Be proactive to ensure that your pet will be taken care of.”

MuttShack and PetSmart Charities set up ad hoc facilities for the animals at both shelters.

The Red Cross shelter, run by Madison Burtchaell of the Orange County Red Cross was very accommodating about allowing a small emergency pet shelter adjacent to the School.

Barbara A. Fought of PetSmart Charities, an organization that works with animal welfare organizations and provide assistance in disasters, provided crates and emergency supplies.

MuttShack and Red Cross volunteers, Martin St. John, Tom Hamilton, and Steve Meissner helped assemble the crates to secure a safe environment for evacuated pets.

It was a great relief for evacuees who had camped out in the parking lot to finally leave their vehicles and relax at the shelter, setting up their cots to grab some sorely needed rest.

Firefighters and residents reported loss of wildlife and animals. The Esperanza fire burned 34 homes, consumed 40,000 acres and cost five Firefighters their lives before it was contained four days later on October 30. Firefighting operations cost nearly $10 million.

MuttShack Animal Rescue is a 501(c) 3 non-profit organization active in disasters and dedicated to the rescue, rehabilitation and care of lost or discarded dogs, cats and other animals.

Presidential aides and state television announced yesterday that the Nigerian president, Umaru Yar’Adua, died.

Yar’Adua ascended to the presidency in 2007, but was later taken ill, and had not been publicly seen for the last few months. He was hospitalised in Jeddah, Saudi Arabia, to get inflammated tissue around his heart treated; it was later diagnosed as acute pericarditis.

According to the BBC, Nigerian reports indicated the president died between 21.00 and 22.00 local time (20.00 to 21.00 UTC) in Abuja, the capital.

Goodluck Jonathan, the vice-president, became the acting president this February; under the constitution, he is to now be sworn in formally and will appoint a new vice-president.

The Nigerian Television Authority broadcast the news, saying: “The president and commander-in-chief of the armed forces, Umaru Musa Yar’Adua, died a few hours ago at the presidential villa. Security aides notified the national security adviser, General Anou Bissou, who immediately called the acting president. The late president has been ill for some time.”

Ima Niboro, a spokesman for Goodluck Jonathan, commented: “The acting president is very sad with what has happened. The nation is mourning.” Tomorrow is to be a national holiday, and Nigeria will observe a week of mourning for the deceased president.

In his statement, acting president Jonathan said: “Nigeria has lost the jewel on its crown, and even the heavens mourn with our nation tonight.”
