Chancellor of the Exchequer Rishi Sunak announced the UK’s 2021 budget on Wednesday in the House of Commons. This comes amid significant damage to the country’s economy from the COVID-19 pandemic, in which over 700 thousand people have lost their jobs, with the economy shrinking by 10%.
Sunak announced an extension of the furlough scheme, which had been paying employees who could not work due to the pandemic 80% of their wages. He said it would be extended until September. The scheme also mentioned firms would have to pay 10% of this in July, and 20% in the months of August and September as the scheme ends. It was also announced that support for self-employed people would continue, with another grant for between February and April.
Other support for workers included the minimum wage increasing to £8.91/hour from April, and an existing £20 weekly increase in Universal Credit being extended through September.
Sunak also announced some changes to taxation in the country, with corporation tax rising to 25% in April 2023. Sunak said that this would be the lowest rate in the G7, and that businesses would only be taxed if they made profits of over £250 thousand, which is only 10% of companies. Companies with profits of less than £50 thousand will continue to pay 19% corporation tax. Sunak said that income tax, national insurance, and VAT would not change in this budget with alcohol and fuel duty continuing to be frozen.
For hospitality firms, VAT will continue to be frozen at a reduced rate of five percent. The contactless payment limit will be increased from £45 to £100 this year. New freeports were also announced in locations at East Midlands Airport; Felixstowe and Harwich; Humber; Liverpool City Region; Plymouth; Solent; and Thames and Teesside. These would allow reduced customs costs, and encourages investment.

Neanderthals ‘knew what they were doing’: Archæologist Dr Naomi Martisius discusses her findings about Neanderthals’ behaviour with Wikinews

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.
