Ancient DNA Reveals Phoenicians' Surprising Ancestry
Phoenician civilization emerged more than 3,000 years ago, centred around what is now Lebanon, before expanding across the Mediterranean Sea. Middle Eastern Phoenician city-states eventually fell to other groups, but the culture thrived farther west—most notably in Carthage, in what is now Tunisia, until its destruction in 146 BC.
Phoenician city-states shared languages—recorded with an alphabet that was a precursor to Greek and Latin letters—religious practices and maritime trading economies. Many researchers have presumed that their inhabitants also shared ancestries connected to the culture's Middle Eastern origins.

To study this history, population geneticist Harald Ringbauer at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and his colleagues analysed the DNA from the remains of around 200 people from Phoenician archaeological sites in the Middle East, Europe and North Africa.
Ancestry puzzle
To Ringbauer's surprise, people from Mediterranean outposts of Phoenician culture—also known as Punic people—shared no ancestry with ancient Middle Easterners, even those from sites linked to Phoenicians and their forebears the Canaanites.
But neither did Punic people's genomes always resemble those of people from other local populations, such as those in Sardinia and Ibiza. Instead, Punic people shared an ancestry profile resembling those of ancient inhabitants of Greece and Sicily. Over time, North African ancestry entered the mix—reflecting the rise of Carthage after 500 BC.
This unique mixture of ancestries is probably the result of a regular influx of diverse people connected by a 'Mediterranean highway' maintained by trade between Phoenician outposts, says Ringbauer. The study identified related individuals found at distant archaeological sites, including a pair of possible second cousins, one from North Africa and one from Sicily.
After the fall of Phoenician city-states in the Middle East, people with ancestry from this region might have been cut off from the Mediterranean highway, says Ringbauer.
The absence of Middle Eastern ancestry in Punic people doesn't surprise Pierre Zalloua, a geneticist at Khalifa University in Abu Dhabi, United Arab Emirates. 'The Phoenicians were a culture of integration and assimilation,' he says. 'They settled where they sailed.'
Ringbauer would like to know why diverse Mediterranean people adopted Phoenician culture, instead of sticking to their existing practices. 'How can there be such a disconnect?' he wonders. 'Does this mean Phoenician culture was like a franchise that others could adopt? That's one for the archaeologists.'

Miniature Neutrino Detector Catches Elusive Particles at Nuclear Reactor
A relatively small detector caught neutrinos from a nuclear reactor using a technique known as coherent scattering Physicists have caught neutrinos from a nuclear reactor using a device weighing just a few kilograms, orders of magnitude less massive than standard neutrino detectors. The technique opens new ways to stress-test the known laws of physics and to detect the copious neutrinos produced in the hearts of collapsing stars. 'They finally did it,' says Kate Scholberg, a physicist at Duke University in Durham, North Carolina. 'And they have very beautiful result.' The experiment, called CONUS+, is described on 30 July in Nature. Challenging quarry Neutrinos are elementary particles that have no electrical charge and generally don't interact with other matter, making them extraordinarily difficult to detect. Most neutrino experiments catch these elusive particles by observing flashes of light that are generated when a neutrino collides with an electron, proton or neutron. These collisions occur extremely infrequently, so such detectors typically have masses of tonnes or thousands of tonnes to provide enough target material to gather neutrinos in relevant numbers. [Sign up for Today in Science, a free daily newsletter] Scholberg and her collaborators first demonstrated the mini-detector technique in 2017, using it to catch neutrinos produced by an accelerator at Oak Ridge National Laboratory in Tennessee. The Oak Ridge particles have slightly higher energies than those made in reactors. As a result, detecting reactor neutrinos was even more challenging, she says. But lower-energy neutrinos also allow for a more precise test of the standard model of physics. Scholberg's COHERENT detector was the first to exploit a phenomenon called coherent scattering, in which a neutrino 'scatters' off an entire atomic nucleus rather than the atom's constituent particles. Coherent scattering uses the fact that particles of matter can act as waves — and the lower the particles' energy, the longer their wavelength, says Christian Buck, a leader of the CONUS collaboration. If the wavelength of a neutrino is similar to the nucleus's diameter, 'then the neutrino sees the nucleus as one thing. It doesn't see the internal structure', says Buck, who is a physicist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. The neutrino doesn't interact with any subatomic particles, but does cause the nucleus to recoil — depositing a tiny amount of energy into the detector. Catching sight of a nucleus Coherent scattering occurs more than 100 times as frequently as the interactions used in other detectors, where the neutrino 'sees' a nucleus as a collection of smaller particles with empty space in between. This higher efficiency means that detectors can be smaller and still spot a similar number of particles in the same time frame. 'Now you can afford to build detectors on the kilogram scale,' Buck says. The downside is that the neutrinos deposit much less energy at the nucleus. The recoil induced on a nucleus by a neutrino is comparable to that produced on a ship by a ping-pong ball, Buck says — and has until recent years has been extremely challenging to measure. The CONUS detector is made of four modules of pure germanium, each weighing 1 kilogram. It operated at a nuclear reactor in Germany from 2018 until that reactor was shut down in 2022. The team then moved the detector, upgraded to CONUS+, to the Leibstadt nuclear power plant in Switzerland. From the new location, the team now reports having seen around 395 collision events in 119 days of operation — consistent with the predictions of the standard model of particle physics. After COHERENT's landmark 2017 result, which was obtained with detectors made of caesium iodide, Scholberg's team repeated the feat with detectors made of argon and of germanium. Separately, last year, two experiments originally designed to hunt for dark matter reported seeing hints of low-energy coherent scattering of neutrinos produced by the Sun. Scholberg says that the standard model makes very clean predictions of the rate of coherent scattering and how it changes with different types of atomic nucleus, making it crucial to compare results from as many detecting materials as possible. And if the technique's sensitivity improves further, coherent scattering could help to push forward the state of the art of solar science. Researchers say that coherent scattering will probably not completely replace any existing technologies for detecting neutrinos. But it can spot all three known types of neutrino (and their corresponding antiparticles) down to low energies, whereas some other techniques can capture only one type. This ability means it could complement massive detectors that aim to pick up neutrinos at higher energies, such as the Hyper-Kamiokande observatory now under construction in Japan.

Could a single shot at birth shield kids from HIV for years?
There's potentially exciting news from a trial conducted in monkeys: A single shot of gene therapy given to newborn monkeys appears to shield them from HIV, the virus that causes AIDS, for at least three years. Of course, studies conducted in animals don't always pan out in humans. But scientists say that if it does, it could save the lives of babies and children still imperiled by HIV. The study authors estimate that more than 100,000 children worldwide (largely in subSaharan Africa) are believed to contract HIV soon after birth, primarily via breastfeeding with an HIV+ mother. "Nearly 300 children are infected with HIV each day," said lead author Dr. Amir Ardeshir, associate professor of microbiology and immunology at the Tulane National Primate Research Center in New Orleans. "This approach could help protect newborns in high-risk areas during the most vulnerable period of their lives." His team published its findings July 30 in Nature. It noted that the new work hinges on the notion that in the first few weeks of a primate's life -- humans are primates, too -- the body's immune system is naturally more tolerant of "invaders," including gene therapies. The research focused on a tried-and-true form of HIV-fighting gene therapy. It works by programming cells to continuously produce HIV-fighting antibodies. The gene therapy was piggybacked onto a harmless adeno-associated virus (AAV) to help deliver it to the muscle cells of newborn rhesus macaques. Muscle cells were chosen because they are particularly long-lived, Ardeshir's team explained. The gene therapy instructs these cells to produce broadly neutralizing antibodies, or bNAbs, which are capable of neutralizing multiple strains of HIV. It's not the first time bNAbs have been used in gene therapy to fight HIV. However, in prior trials repeat injections were required to keep the immune system vigilant. In the new trial, "we turn these muscle cells -- which are long-lived -- into micro factories that just keep producing these antibodies," Ardeshir explained. When such an approach is used in older monkeys, however, the animals' robust immune systems turn against the therapy, shutting it down. That didn't happen when Ardeshir's team introduced it during a macaque's first few weeks of life. All of the monkeys who got a single shot of bNAbs therapy soon after birth were shielded from infection with HIV for at least three years, with no need for a booster. Tulane researchers said that's roughly the equivalent of a treatment that could ward off HIV in humans deep into adolescence. If the gene therapy was delivered even a bit later -- 8 to 12 weeks after birth -- the young monkey's more developed immune system swung into action to fight it, eroding its effectiveness. Giving the shot soon after birth seemed key, Ardeshir said. "This is a one-and-done treatment that fits the critical time when these mothers with HIV in resource-limited areas are most likely to see a doctor," he noted in a Tulane news release. "As long as the treatment is delivered close to birth, the baby's immune system will accept it and believe it's part of itself." Will it work in human babies? That's not entirely clear, since it's possible infants might be less amenable than monkeys to therapies that are delivered via AAV, the team said. The monkey trial also used only one strain of simian-human immunodeficiency virus, which is similar in some ways to HIV but may not reflect the variety of circulating strains of HIV strains. Still, the research team is hopeful. Giving families a one-shot preventive tool to protect their children would be especially useful in areas where access to repeat medical treatments can be tough, the researchers said. "Nothing like this was possible to achieve even 10 years ago," Ardeshir said. "This was a huge result, and now we have all the ingredients to take on HIV."

Wild tattoos of 2,500-year-old Siberian ‘ice mummy' revealed for first time
The ornate tattoos of a 2,500-year-old Siberian 'ice mummy' have finally been revealed using advanced imaging technology, according to a report. High-resolution images derived using infrared technology show the long-dead 50-year-old woman was inked-up across her body with tribal animal designs, the BBC reported. 5 The mummy was pulled from the permafrost near Russia's Altai Mountains in 1993. M. Vavulin Advertisement The intricate and ornate tats show leopards, a stag, a rooster, and a griffin-like creature. Her arms were tattoo'd with the leopard and stag, the half-lion half-eagle beast was on her leg, and the rooster was tatted on the mummy's thumb, according to researchers. 'The insights really drive home to me the point of how sophisticated these people were,' the study's lead author Dr. Gino Caspari, from the Max Planck Institute of Geoanthropology, told BBC. Advertisement 5 Left forearm tatoo. D. Riday 5 Right forearm tattoo. D. Riday 'This made me feel like we were much closer to seeing the people behind the art, how they worked and learned. The images came alive,' Dr. Caspari said. The female mummy is one of three fleshickles plucked from the permafrost on the Okok Plateau in the Altai Mountains in Russia in 1993. She was part of a Pazyryk tribe — horse-riding nomads who dominated the Eurasian plains from the 6th to 3rd centuries BC. Advertisement 5 Hand tattoos, including rooster on the thumb. D. Riday The 'Ice Maiden's' tattoos have proved to be an insight into the mysterious Pazyryk tribe who were apparently dedicated and expert tattoo artists. 'If I was guessing, it was probably four and half hours for the lower half of the right arm, and another five hours for the upper part,' Dr. Caspari said, adding, 'That's a solid commitment from the person.' 'It would need to be performed by a person who knows health and safety, who knows the risks of what happens when the skin is punctured.' Advertisement Much like contemporary tattoos, the process included a stencil of the design on the skin first with the ink being inserted under the skin with a needle-like tool, the researchers claimed. 5 The infrared imaging of the mummy's skin showed the leopard print of one of the tattoos. M Vavulin 'And back in the day it was already a really professional practice where people put a lot of time and effort and practice into creating these images and they're extremely sophisticated,' said Dr. Caspari. 'It suggests that tattoos were really something for the living with meaning during life, but that they didn't really play much of a role in the afterlife.'
