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.

On Monday, a water main broke in the US city of White Plains, New York, cutting off the water supply to most of the city. The burst pipe caused a huge crater to form in a major intersection in the heart of the city, flooding the streets. Emergency crews were on the scene to repair the pipes in order to restore water service. Almost all customers had water restored by the evening.
The water pipe burst under the road surface at the intersection of Martine Avenue and S. Lexington Avenue in the afternoon. By 5:00 pm EDT (2100 UTC) the city issued an advisory of water outages and stated the Department of Public Works (DPW) had located the problem. Wikinews was on the scene around 6:20 pm and could observe a large crater in the street caused by the amount of water from the burst pipe. Crews from DPW as well as some the fire department were there. Water was no longer rushing uncontrolled into the street.
Shortly thereafter, at 6:30 pm, the city issued a follow-up statement announcing the break had been contained by DPW. Residents were advised to expect the water to perhaps be “discolored” when it initially returned. The city estimated by 9 pm, there would be enough pressure returned to the water system for all to have water. Indeed, News 12 reported, only buildings adjacent to the break were without water service.
White Plains is the county seat for Westchester County, New York, which is also home to the cities New Rochelle and Yonkers which formed the epicenter of the COVID-19 outbreak in New York. Westchester lies directly to the north of New York City.

China’s Xinhua News Agency said Tuesday that at least 53 people were killed in Shanghai during a deadly fire. The blaze, which occurred on Monday at 2:15 p.m. CST (0615 UTC), consumed a 28-story high-rise apartment building in the city’s Jing’an District.
The building was being renovated at the time of the fire, and was home to over 150 families. At least 100 victims have been admitted to area hospitals, although some later died. Most survivors were not seriously injured, but needed treatment for smoke inhalation. Firefighters were still looking for survivors and over 70 were still hospitalized on the morning after the fire.
The fire was the worst in recent Shanghai history and took over 100 fire engines more than four hours to contain. Strong winds blew heavy smoke into the air, hampering rescue efforts by helicopters. The smoke was seen by witnesses around 15 kilometres (9.3 miles) away from the high-rise. The fire was largely extinguished by 6:30 p.m. local time (1000 UTC), allowing fire and rescue officials to enter the building.
The apartment building, built in the late 1990s, was home to mainly retired teachers. Some residents climbed down the scaffolding to escape, while others called for help but were unable to flee the blaze. “I saw at least four or five people hanging onto the scaffolding which covers the building, screaming for help,” said Li Qubo, who was working near the high-rise.
The cause of the fire has not yet been determined, but local residents said fire safety regulations were not strict, and workers often tossed used cigarettes into the building’s hallways. Qiu Jingshu, a 38-year-old worker who was outside the 18th floor when the fire struck, said he saw sparks from welding being done on an adjacent building fly over onto the high-rise. The sparks lit up foam on the scaffolding around the apartment, according to Qiu. “We had tried to put out the blaze, but the fire was so big and spread so quickly that we could barely escape ourselves,” he said. Crews were said to have been installing insulation at the time of the fire, and witnesses saw construction materials on fire before the building was overtaken by flames.
Two nearby buildings were evacuated, and their residents were temporarily sent to local hotels, and a school. Meng Jianzhu, China’s Minister of Public Security, said that an investigation would determine who was responsible for the fire, so they could be punished accordingly. Meng said that a team had been formed under China’s State Council to look into the disaster.
A similar incident occurred in Beijing early last year. In February 2009, the illegal use of fireworks caused a fire that gutted a 34-story building under construction at the time.
Shanghai has a population of about 20 million, housed mainly in high-rise apartments. Many buildings in the city are under construction or being renovated.

A paste containing synthetic tooth enamel can seal small cavities without drilling. Kazue Yamagishi and colleagues at the FAP Dental Institute in Tokyo say that the paste can repair small cavities in 15 minutes.
Currently, fillers don’t stick to such small cavities so dentists must drill bigger holes. Hydroxyapatite crystals, of which natural enamel is made, bond with teeth to repair tiny areas of damage.
Yamagishi and colleagues have tested their paste on a lower premolar tooth that showed early signs of decay. They found that the synthetic enamel merged with the natural enamel. The synthetic enamel also appears to make teeth stronger which will improve resistance to future decay. As with drilling, however, there is still the potential for pain: The paste is strongly acidic to encourage crystal growth and causes inflammation if it touches the gums.
The paste is reported in the journal Nature.

Real estate tycoon Donald Trump on CNN’s Anderson Cooper 360 reacted to Rosie O’Donnell’s comments about him on the The View.
“Rosie has some real problems,” Trump said on Anderson Cooper 360. “Rosie’s a loser. She’s been a loser always.”
It started when Miss USA Tara Conner was caught under age drinking. Trump, the owner of the Miss Universe Organization, gave her a second chance. Rosie O’Donnell called him a “Pimp” on her personal blog and said he has no right to be “the moral compass for 20-year-olds in America” on The View, which she co-hosts.
“Rosie got mentally beaten up by me,” Trump told The Post yesterday, “because she’s a mental midget, a low-life.”
“It’s too bad a degenerate is able to get away with things like that,” Trump said yesterday. “I met Tara the night of the pageant and didn’t see her again until she got into trouble.”
Trump said that he would sue her over her comment.
“It will never end on my behalf because I’ve exposed Rosie for what she is: a very dumb human being,” Trump told the Associated Press. “She’s got no intelligence, but I’ve known that for a long time. Unfortunately, Rosie’s pulled the wool over the public.”
When CNN contacted O’Donnell, one of her representatives said she was unavailable for comment. CNN’s Anderson Cooper 360 also said that she is welcome to comment anytime.

Volunteers from across the United States and some foreign countries gathered Friday to start an unofficial border patrol project.
They converged on the town of Tombstone, Arizona to take part in what organizers call the Minuteman Project.
Many came with personal firearms, cell phones or walking canes.
Most estimates numbered the group at 400 to 450 people, recruited from the Internet, far less than the 1,300 the organizers had hoped for, but “it was enough to send a message,” according to Rep. Tom Tancredo, R-Colo.
“The federal government has walked away from this border,” he told some volunteers. He gained support and popularity for his stance against illegal immigration, but was characterized as anti-immigration in general.
“We are here to exercise what is a basic American right: free speech and the right to assemble,” he said.
Local citizens such as Luis Martinez, a third-generation Tombstone-area resident, were very unhappy with the developments. “They’ve come here to cause problems — to fight. Not to solve problems.
“I work in a ranch and all the ranchers use labor from the other side” of the border.
As Martinez fought back tears, he said he wanted to see the throngs leave Tombstone and go home.
During speeches delivered at orientation meetings, Rep. Tancredo was applauded loudly as he dismissed criticism from those who have called the volunteers racists and xenophobes. His fellow [[Republican Party (US)|Republican}}, President George Bush, described the group as “vigilantes.” Mexican President Vicente Fox used the term cazamigrantes — immigrant hunters.
Tancredo said: “We are saying to our government, ‘Please enforce the law,’ That is not a radical idea. That is not a vigilante idea. It is an American concept: the rule of law.”
Many of the volunteers, some from as far away as Italy, are bedding down in the nearby Miracle Valley Bible College for about $5 a night. Others are camping on the grounds of the run-down campus, about two miles north of the border.
Opposing sides were on the streets in Tombstone, although it appeared there was little contact or friction. Local, state and federal officers had mobilized in case confrontations arose.
James Gilchrist, a former Marine and a retired accountant from Aliso Viejo, Arizona, who ran the sign-up effort, said he expected more than 1,000 volunteers to help highlight the 30-day effort. The project’s goal is to patrol 23 miles of the San Pedro Valley, watch the border, and report illegal activity to law enforcement officials.
Many people fear that the project could result in vigilante violence. Organizers hope it causes the U.S. government to increase border patrols.
Tombstone is best known as the site of the 1881 shootout at the OK Corral.

Scientists in the UK have developed a new way to ensure boiled eggs are perfectly cooked thanks to a brand new hi-tech logo being printed on shells.
After cooking starts, people will be able to see if their egg is soft, medium or hard-boiled with the help of a thermochromic print which appears in black ink on the egg’s shell.
The eggs will be sold to consumers in the UK within the next few months. A spokeswoman for Lion Quality, the assurance scheme which came up with the idea, said: “We had a lot of inquiries from people which sparked an interest in the industry. We said OK, this is a big issue – people can’t even boil an egg.”
Gilly Beaumont, from B&H Colour Change, the company which created the logos, said: “We are still perfecting the technology, but we are very excited at the prospect of sorting a problem that has wound people up at breakfast time for decades.”
The most successful way to cook an egg has baffled some of the greatest chefs in the past. In 1998, Delia Smith dedicated a whole episode of her How To Cook programme on the best way to boil an egg. And last year, a survey carried out by the magazine Waitrose Food Limited showed five top chefs all had different techniques.
