Plastic surgeon to the stars Dr. Frank Ryan has died in a car accident at age 50. It is reported that the Jeep Ryan was driving crashed over the side of the Pacific Coast Highway and landed on rocks. Lifeguards were first on the scene and unsuccessfully tried to rescue Ryan. It is thought that no other vehicle was involved in the incident.

Dr. Ryan, a celebrity in his own right, performed plastic surgery on several stars including Janice Dickinson, Gene Simmons, Shauna Sand and Adrianne Curry. He appeared on several television shows and became one of the first people to perform plastic surgery on television in 1995.

A representative for Janice Dickinson released a statement about the death of Ryan. She said “Janice is deeply, deeply anguished! She is stunned and wants the world to know what a genius Dr. Ryan was.”

Ryan was traveling with his pet dog at the time of the crash; the dog was found seriously injured in the ocean and was transported to a local veterinarian. Dr. Ryan was pronounced dead at the scene.

Macomb, New York Councilman Steve Burke took some time to speak with Wikinews about his campaign for the U.S. Democratic Party’s 2016 presidential nomination.

Burke, an insurance adjuster and farmer, was elected councilman in Brookhaven, New York in 1979. He left the town after being accused and found not guilty of bribery in the 1980s. Since 1987 he has served as Macomb councilman off-and-on and currently holds the post. From 1993 to 1996 and 1999 to 2002 he worked as chairman of the Democratic Party of St. Lawrence County, New York. Among his many political campaigns, Burke unsuccessfully sought the Democratic Party’s presidential nomination in 1992 and recently attempted to run for U.S. Congress in 2014 but too many of his ballot petition signatures were found invalid. Burke filed with the Federal Election Commission to run for president in the 2016 election on September 18, 2015 and has qualified for the first-in-the-nation New Hampshire Primary.

With Wikinews reporter William S. Saturn?, Burke discusses his political background, his 2016 presidential campaign, and his policy proposals.

Wagga Wagga, New South Wales —Sunday, Governor-General of Australia, Quentin Bryce and her husband, Michael Bryce, visited the city of Wagga Wagga to launch the Junior Teams event and present the awards to the winners at the 2013 Allen’s Coaches World Championship Gumi, meet the North Wagga Wagga residents who were affected by the March 2012 floods and meet a small group of volunteers from the NSW RFS, SES and the VRA at a community barbecue at Wagga Beach.

After the Gumi presentations, Governor-General Bryce addressed the media about the Gumi, stating that “It’s so quirky and I love the way it brings this community together, this community that’s known for its fantastic spirit.” She also commented on the floods which affected the suburb of North Wagga in March 2012. Bryce stated that “A very special thing for me was being at North Wagga Wagga this morning, to see people again whom I meet almost a year ago after the devastation of the floods in that part of the city, […] So many people have a long way to recover but their spirit, resilience, courage and determination, what they’ve been though, is a source for inspiration to all of us.”

New ‘deadly’ sexual enhancement products have been found in Singaporean markets and can cause serious side effects on users.

The Health Sciences Authority (HSA) announced the presence of the illegal drugs, known as Power 1 Walnut, Santi bovine penis erecting capsule, Zhong Hua Niu Bian and fake Cialis, which have been discovered over the past 3 months. Santi bovine penis erecting capsule has been found to contain high amounts of glibenclamide, a potent drug used to treat diabetes. The tablets also contain sildenafil and tadalafil – potent western medicines used to treat erectile dysfunction. Zhong Hua Niu Bian also contains sildenafil and glibenclamide.

High consumption of the tablets can be potentially deadly as the glibenclamide in the capsules can lead to drastically reduced blood sugar levels which can lead to seizures, stroke, coma or death. Consuming half of a Power 1 Walnut capsule has led to unconsciousness and frothing at the mouth.

Consumption of Power 1 Walnut has led to the death of a middle age man last week who fell into a coma. Currently, one death and two cases of coma have been reported from the total of 89 hospitalised cases linked with the consumption of the illegal drugs. It has been revealed that patients obtained the drugs by purchasing them from illegal peddlers located in various parts of Singapore.

The HSA has advised people to stop consuming the drugs and to report on any cases of consumption to them.

Michael Gurian, psychologist and author of “What Could He Be Thinking?“, has claimed to identify approximately one hundred structural differences between male and female brains in a recent study. Gurian comments:

“Men, because we tend to compartmentalize our communication into a smaller part of the brain, we tend to be better at getting right to the issue, the more female brain (will) gather a lot of material, gather a lot of information, feel a lot, hear a lot, sense a lot.“

One major structural difference that Gurian has made clear is that males generally have more activity in the mechanical centers of the brain, while women have more activity in centers of the brain dedicated to verbal communication and emotion. A clear example of this is the hypothetical situation of giving a child a toy. He explains it as such:

“That doll becomes life-like to that girl, but you give it to a two-year-old boy and you are more likely, not all the time, but you are more likely than not to see that boy try to take the head off the doll. He thinks spatial-mechanical. He’s using the doll as an object.“

Another expert, Dr. Marianne Legato, says it all boils down to genetics, noting that the Y chromosome (which only males carry) has “at least 21 unique genes unique to males which control many of the body’s operations down to the level of the cells.”

Gurian agrees that culture is significant in brain development, but argues that biology plays an equally important role. He makes a point of how the MRI scans show that the female corpus callosum, the center of the brain which regulates communication between the brain’s hemispheres, is larger than the male’s. On the other hand, the scans also show that information flows more freely between the hemispheres of the male brain.

The exact role that brain structure plays in behavior, however, has been an area of considerable contention in science for literally hundreds of years. Early studies in craniometry conducted by Paul Pierre Broca were used to attempt to distinguish differences between human races, though have now been dismissed as scientific racism. The nature-nurture debate has raged for centuries in a variety of forms, without yet any clear resolution as to the role in which innate biological tendencies interact with environmental conditions or willed behavior. As such, studies relating to brain structure and claims to innate behavior often generate substantial controversy.

MIT anthropologist of science Joseph Dumit’s study of brain imaging in his book Picturing Personhood: Brain Scans and Biomedical Identity, noted that the apparent “transparency” of such pictures (the appearance that they can be easily interpreted by laymen, when they are often the source of ambiguity and dispute by even highly-trained neurosurgeons) has led to their proliferation as indicators of objective truth in media and in courts of law, and that such conclusions are often knowingly exaggerated by the specialists creating the images for better visual effect.

The timing of Gurian’s book comes on the heels of another controversy over gender differences sparked by comments made by Harvard president Lawrence Summers, who blamed low numbers of women in the sciences on genetic differences. Summers has been criticized by a large number of academics and scientists, as well as by many news publications, in the wake of what he was reported as saying during a conference on January 14.

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.

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.
