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.

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ^{((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????.} He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ^{((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.}

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

On the morning of January 4, 2008, while at the 2008 World Junior Ice Hockey Championships, 19-year-old goalie Steve Mason received a phone call from Canada informing him that he was traded by the Ontario Hockey League’s London Knights to the Kitchener Rangers.

In a press release Friday, Kitchener Rangers Head coach and General Manager Peter DeBoer announced the trade to the Knights. In return for obtaining Mason, the Rangers have sent the Knights, Centre Phil Varone, Defenceman Steve Tarasuk along with 2nd, 3rd and 4th round draft picks in 2011 and a 2nd round pick in 2012.

Mason said that he had an enjoyable time playing for the London Knights, but nonetheless, he believes that he has a bright future playing for the Kitchener Rangers. He also notes that he doesn’t want the trade to distract him from playing in the Gold Medal Game, against Team Sweden.

Team Canada won the game in overtime 3-2.

2020 Melbourne Lord Mayor candidate Wayne Tseng answered some questions about his campaign for the upcoming election from Wikinews. The Lord Mayor election in the Australian city is scheduled to take place this week.

Tseng runs a firm called eTranslate, which helps software developers to make the software available to the users. In the candidate’s questionnaire, Tseng said eTranslate had led to him working with all three tiers of the government. He previously belonged to the Australian Liberal Party, but has left since then, to run for mayorship as an independent candidate.

Tseng is of Chinese descent, having moved to Australia with his parents from Vietnam. Graduated in Brisbane, Tseng received his PhD in Melbourne and has been living in the city, he told Wikinews. Tseng also formed Chinese Precinct Chamber of Commerce, an organisation responsible for many “community bond building initiatives”, the Lord Mayor candidate told Wikinews.

Tseng discussed his plans for leading Melbourne, recovering from COVID-19, and “Democracy 2.0” to ensure concerns of minorities in the city were also heard. Tseng also focused on the importance of the multi-culture aspect and talked about making Melbourne the capital of the aboriginals. Tseng also explained why he thinks Melbourne is poised to be a world city by 2030.

Tseng’s deputy Lord Mayor candidate Gricol Yang is a Commercial Banker and works for ANZ Banking Group.

Currently, Sally Capp is the Lord Mayor of Melbourne, the Victorian capital. Capp was elected as an interim Lord Mayor in mid-2018 after the former Lord Mayor Robert Doyle resigned from his position after sexual assault allegations. Doyle served as the Lord Mayor of Melbourne for almost a decade since 2008.

Retail store group Walmart has removed an infant formula from over three thousand of their stores in the United States. The decision was taken in the aftermath of the death of a baby who suffered from Cronobacter sakazakii, an infection which is extremely rare but poses a significant risk to babies born recently and those born prematurely should they contract it. A second newborn baby has also contracted the infection, which is most frequently discovered in plants like rice and wheat.

Ongoing tests are now attempting to establish whether or not the powdered infant formula is connected to the bacterial infection the two babies suffered from in the US state of Missouri. A statement from Walmart says that the company is taking the product Enfamil Newborn Formula off their shelves “out of an abundance of caution”. Speaking on behalf of Walmart, Dianna Gee stated that the group express their “deepest condolences” to the family of Avery Cornett, who died after removal from life support. Gee informed Agence France-Presse that lot number ZP1K7G had been removed and “Walmart customers who may have purchased the item at our stores can return it for a full refund or exchange it for another brand of formula”.

The manufacturer of Enfamil Newborn Formula has also stated that tests made before shipment of the product came back as negative. Chris Perille, a spokesperson for Enfamil manufacturer Mead Johnson Nutrition, has said: “The batch of our product used by the child’s family tested negative for Cronobacter when it was produced and packaged, and that has been reconfirmed from our batch records following this news”. Mead Johnson are “highly confident in the safety and quality of our products — and the rigorous testing we put them through” and is “working with the health authorities to support their efforts to identify the source or cause of this infant’s infection,” according to Perille. The U.S. government has reportedly made no recall of the product.

The Missouri Department of Health and Senior Services has referred the infant formula to the Centers for Disease Control and Prevention and the Food and Drug Administration for examination and has advised parents that “powdered infant formulas are not commercially sterile products” and destroying bacteria amongst the production process may not be possible, while “no exclusively breastfed infants have been reported to have” contracted Cronobacter sakazakii. Pending test completion, “it cannot be determined whether the illness is linked to Enfamil Newborn Formula 12.5 oz. cans lot #ZP1K7G or an outside source”, according to a statement from the Missouri Department of Health and Senior Services. The department has also suggested that parents observe the World Health Organisation’s ‘Guidelines for the safe preparation, storage and handling of powdered infant formula’, which recommends “washing your hands with soap and water, thoroughly sterilizing all feeding equipment in hot, soapy water and preparing enough formula for only one feeding at a time”.

Results of the second phase in an ongoing major study of the spiritual lives of college students was released Wednesday, April 13 by a research center at UCLA. The study is a groundbreaking attempt to gain insight into the spiritual lives and concerns of students and improve how faculties and administrators at US colleges and universities address this part of their students’ lives.

The study, named The Spiritual Life of College Students, was conducted by the Higher Education Research Institute (HERI), a research center of higher education in the United States. HERI is based in the Graduate School of Education & Information Studies (GSE&IS) at University of California, Los Angeles (UCLA).

HERI also produces a widely-cited annual Survey of Entering Freshman through its Cooperative Institutional Research Program (CIRP) program.
