Europe's oldest lake settlement uncovered in Albania
The team, from Switzerland and Albania, spends hours each day about three metres (9.8 feet) underwater, painstakingly retrieving wooden stilts that supported houses.
The are also collecting bones of domesticated and wild animals, copper objects and ceramics, featuring detailed carvings.
Albert Hafner, from the University of Bern, said similar settlements have been found in Alpine and Mediterranean regions, but the settlements in the village of Lin are half a millennium older, dating back between 6,000 and 8,000 years.
"Because it is under water, the organic material is well-preserved and this allows us to find out what these people have been eating, what they have been planting," Hafner said.
Multiple studies show that Lake Ohrid, shared by North Macedonia and Albania, is the oldest lake in Europe, at over one million years.
The age of the findings is determined through radiocarbon dating and dendrochronology, which measures annual growth rings in trees. More than one thousand wood samples have been collected from the site, which may have hosted several hundred people.
It is believed to cover around six hectares, but so far, only about 1 per cent has been excavated after six years of work.
Hafner said findings show that people who lived on the lake helped to spread agriculture and livestock to other parts of Europe.
"They were still doing hunting and collecting things but the stable income for the nutrition was coming from the agriculture," he said.
Albanian archaeologist Adrian Anastasi said it could take decades to fully explore the area.
"(By) the way they had lived, eaten, hunted, fished and by the way the architecture was used to build their settlement we can say they were very smart for that time," Anastasi said.

Novartis to pay Matchpoint up to $1 billion to develop anti-inflammatory therapies
Swiss drugmaker Novartis will pay up to $1 billion to U.S. biotech Matchpoint Therapeutics to develop oral drugs for several inflammatory diseases. Matchpoint said on Thursday it will use its technology to develop drugs that block the activity of a specific protein, helping to lower the production of inflammation-causing signals. The company will lead the research and drug development process, using the funding from Novartis. If Novartis exercises its option to exclusively license the program, the drugmaker will have global rights to develop and commercialize all products resulting from the collaboration. Matchpoint said it will receive up to $60 million in upfront payment and research funding, with up to $1 billion in total potential payments, including option exercise fee, and development and commercial milestones.

Europe's oldest lake settlement uncovered in Albania
LIN, Albania :Archaeologists working on the shores of Ohrid Lake in Albania are convinced they have uncovered the oldest human settlement built on a European lake, finding evidence of an organised hunting and farming community living up to 8,000 years ago. The team, from Switzerland and Albania, spends hours each day about three metres (9.8 feet) underwater, painstakingly retrieving wooden stilts that supported houses. The are also collecting bones of domesticated and wild animals, copper objects and ceramics, featuring detailed carvings.

Three-person IVF technique spared children from inherited diseases: Scientists
Eight children in the United Kingdom have been spared from devastating genetic diseases thanks to a new three-person in vitro fertilisation (IVF) technique, scientists from Newcastle University reported on Wednesday (Jul 16). The technique, which is banned in the United States, transfers pieces from inside the mother's fertilised egg - its nucleus, plus the nucleus of the father's sperm - into a healthy egg provided by an anonymous donor. The procedure prevents the transfer of mutated genes from inside the mother's mitochondria, the cells' energy factories, that could cause incurable and potentially fatal disorders. Mutations in mitochondrial DNA can affect multiple organs, particularly those that require high energy, such as the brain, liver, heart, muscles and kidneys. One of the eight children is now two years old, two are between the ages of one and two, and five are infants. All were healthy at birth, with blood tests showing no or low levels of mitochondrial gene mutations, the scientists reported in the New England Journal of Medicine. All have made normal developmental progress, they said. The results "are the culmination of decades of work", not just on the scientific or technical challenges but also in ethical inquiry, public and patient engagement, law-making, drafting and execution of regulations, and establishing a system for monitoring and caring for the mothers and infants, reproductive medicine specialist Dr Andy Greenfield of the University of Oxford, who was not involved in the research, said in a statement. The researchers' "treasure trove of data" is likely to be the starting point of new avenues of investigation, Greenfield said. Often during IVF screening procedures, doctors can identify some low-risk eggs with very few mitochondrial gene mutations that are suitable for implantation. But sometimes all of the eggs' mitochondrial DNA carries mutations. In those cases, using the new technique, the UK doctors first fertilise the mother's egg with the father's sperm. Then they remove the fertilised egg's 'pronuclei', that is, the nuclei of the egg and the sperm, which carry the DNA instructions from both parents for the baby's development, survival and reproduction. Next, they transfer the egg and sperm nuclei into a donated fertilised egg that has had its pronuclei removed. The donor egg will now begin to divide and develop with its healthy mitochondria and the nuclear DNA from the mother's egg and the father's sperm. This process, detailed in a second paper in the journal, 'essentially replaces the faulty mitochondrial DNA (mtDNA) with healthy mtDNA from the donor', senior researcher Mary Herbert, professor of reproductive biology at Newcastle, said at a press briefing. Blood levels of mtDNA mutations were 95 per cent to 100 per cent lower in six newborns, and 77 per cent to 88 per cent lower in two others, compared to levels of the same variants in their mothers, the researchers reported in a second paper. "These data indicate that pronuclear transfer was effective in reducing transmission of mtDNA disease," they said. The procedure was tested in 22 women whose babies were likely to inherit such genes. In addition to the eight women who delivered the children described in this report, another one of the 22 is currently pregnant. Seven of the eight pregnancies were uneventful; in one case, a pregnant woman had blood tests showing high lipid levels. There have been no miscarriages. The authors of the current reports have also tried transplanting the nucleus of a mother's unfertilized egg into a donor egg and then fertilising the donor egg afterwards, but they believe their new approach may more reliably prevent transmission of the genetic disorders. In 2015, the UK became the first country in the world to legalise research into mitochondrial donation treatment in humans. That same year in the US, pronuclear transfer was effectively banned for human use by a congressional appropriations bill that prohibited the Food and Drug Administration from using funds to consider the use of "heritable genetic modification".
