The exceptional excavation of a Stone Age burial site was carried out in Majoonsuo, situated in the municipality of Outokumpu in Eastern Finland. The excavation produced microscopically small fragments of bird feathers, canine and small mammalian hairs, and plant fibres. The findings gained through soil analysis are unique, as organic matter is poorly preserved in Finland’s acidic soil. The study, led by Archaeologist Tuija Kirkinen, was aimed at investigating how these highly degraded plant- and animal-based materials could be traced through soil analysis.
During the Stone Age in Finland, the deceased were interred mainly in pits in the ground. Little of the organic matter from human-made objects have been preserved in Stone Age graves in Finland, but it is known, on the basis of burial sites in the surrounding regions, that objects made of bones, teeth and horns as well as furs and feathers were placed in the graves.
Teeth and arrowheads found in the red ochre grave
The Trial Excavation Team of the Finnish Heritage Agency examined the site in 2018, as it was considered to be at risk of destruction. The burial place was located under a gravelly sand road in a forest, with the top of the grave partially exposed. The site was originally given away by the intense colour of its red ochre. Red ochre, or iron-rich clay soil, has been used not only in burials but also in rock art around the world.
In the archaeological dig at the burial site, only a few teeth were found of the deceased, on the basis of which they are known to have been a child between 3 and 10 years of age. In addition, two transverse arrowheads made of quartz and two other possible quartz objects were found in the grave. Based on the shape of the arrowheads and shore-level dating, the burial can be estimated to have taken place in the Mesolithic period of the Stone Age, roughly 6,000 years before the Common Era.
What made the excavation exceptional was the near-complete preservation of the soil originating in the grave. A total of 65 soil sample bags weighing between 0.6 and 3.4 kilograms were collected, also comparison samples were taken from outside the grave. The soil was analyzed in the archaeology laboratory of the University of Helsinki. Organic matter was separated from the samples using water. This way, the exposed fibres and hairs were identified with the help of transmitted-light and electron microscopy.

Oldest feather fragments found in Finland
From the soil samples, a total of 24 microscopic (0.2-1.4 mm) fragments of bird feathers were identified, most of which originated in down. Seven feather fragments were identified as coming from the down of a waterfowl (Anseriformes). These are the oldest feather fragments ever found in Finland. Although the origin of the down is impossible to state with certainty, it may come from clothing made of waterfowl skins, such as a parka or an anorak. It is also possible that the child was laid on a down bed.
In addition to the waterfowl down, one falcon (Falconidae) feather fragment was identified. It may have originally been part of the fletching of the arrows attached to the arrowheads, or, for example, from feathers used to decorate the garment.
Dog or wolf hairs?
Besides the feathers, 24 fragments of mammalian hair were identified, ranging from 0.5 to 9.5 mm in length. Most of the hairs were badly degraded, making identification no longer possible. The finest discoveries were the three hairs of a canine, possibly a predator, found at the bottom of the grave. The hairs may also originate, for example, in footwear made of wolf or dog skin. It is also possible a dog was laid at the child’s feet.

“Dogs buried with the deceased have been found in, for example, Skateholm, a famous burial site in southern Sweden dating back some 7,000 years,” says Professor Kristiina Mannermaa, University of Helsinki.
“The discovery in Majoonsuo is sensational, even though there is nothing but hairs left of the animal or animals — not even teeth. We don’t even know whether it’s a dog or a wolf,” she says, adding: “The method used, demonstrates that traces of fur and feathers can be found even in graves several thousands of years old, including in Finland.”
“This all gives us a very valuable insight about burial habits in the Stone Age, indicating how people had prepared the child for the journey after death,” says Kirkinen.
The soil is full of information
Also found were three fragments of plant fibres, which are preserved particularly poorly in the acidic Finnish soil. The fibres were what are known as bast fibres, meaning that they come from, for example, willows or nettles. At the time, the object they were part of may have been a net used for fishing, a cord used to attach clothes, or a bundle of strings. For the time being, only one other bast fibre discovery dating back to the Mesolithic Stone Age is known in Finland: the famed Antrea Net on display in the National Museum of Finland, laced with willow bast fibres.
A fibre separation technique was developed in the study, and is already being applied in subsequent studies. The project has demonstrated the great information value of soil extracted from archaeological sites.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

The European Space Agency is fast-tracking a new mission called Ramses, which will fly to near-Earth asteroid 99942 Apophis and join the space rock in 2029 when it comes very close to our planet — closer even than the region where geosynchronous satellites sit.
Ramses is short for Rapid Apophis Mission for Space Safety and, as its name suggests, is the next phase in humanity’s efforts to learn more about near-Earth asteroids (NEOs) and how we might deflect them should one ever be discovered on a collision course with planet Earth.
In order to launch in time to rendezvous with Apophis in February 2029, scientists at the European Space Agency have been given permission to start planning Ramses even before the multinational space agency officially adopts the mission. The sanctioning and appropriation of funding for the Ramses mission will hopefully take place at ESA’s Ministerial Council meeting (involving representatives from each of ESA’s member states) in November of 2025. To arrive at Apophis in February 2029, launch would have to take place in April 2028, the agency says.
This is a big deal because large asteroids don’t come this close to Earth very often. It is thus scientifically precious that, on April 13, 2029, Apophis will pass within 19,794 miles (31,860 kilometers) of Earth. For comparison, geosynchronous orbit is 22,236 miles (35,786 km) above Earth’s surface. Such close fly-bys by asteroids hundreds of meters across (Apophis is about 1,230 feet, or 375 meters, across) only occur on average once every 5,000 to 10,000 years. Miss this one, and we’ve got a long time to wait for the next.
When Apophis was discovered in 2004, it was for a short time the most dangerous asteroid known, being classified as having the potential to impact with Earth possibly in 2029, 2036, or 2068. Should an asteroid of its size strike Earth, it could gouge out a crater several kilometers across and devastate a country with shock waves, flash heating and earth tremors. If it crashed down in the ocean, it could send a towering tsunami to devastate coastlines in multiple countries.
Over time, as our knowledge of Apophis’ orbit became more refined, however, the risk of impact greatly went down. Radar observations of the asteroid in March of 2021 reduced the uncertainty in Apophis’ orbit from hundreds of kilometers to just a few kilometers, finally removing any lingering worries about an impact — at least for the next 100 years. (Beyond 100 years, asteroid orbits can become too unpredictable to plot with any accuracy, but there’s currently no suggestion that an impact will occur after 100 years.) So, Earth is expected to be perfectly safe in 2029 when Apophis comes through. Still, scientists want to see how Apophis responds by coming so close to Earth and entering our planet’s gravitational field.

“There is still so much we have yet to learn about asteroids but, until now, we have had to travel deep into the solar system to study them and perform experiments ourselves to interact with their surface,” said Patrick Michel, who is the Director of Research at CNRS at Observatoire de la Côte d’Azur in Nice, France, in a statement. “Nature is bringing one to us and conducting the experiment itself. All we need to do is watch as Apophis is stretched and squeezed by strong tidal forces that may trigger landslides and other disturbances and reveal new material from beneath the surface.”

By arriving at Apophis before the asteroid’s close encounter with Earth, and sticking with it throughout the flyby and beyond, Ramses will be in prime position to conduct before-and-after surveys to see how Apophis reacts to Earth. By looking for disturbances Earth’s gravitational tidal forces trigger on the asteroid’s surface, Ramses will be able to learn about Apophis’ internal structure, density, porosity and composition, all of which are characteristics that we would need to first understand before considering how best to deflect a similar asteroid were one ever found to be on a collision course with our world.
Besides assisting in protecting Earth, learning about Apophis will give scientists further insights into how similar asteroids formed in the early solar system, and, in the process, how planets (including Earth) formed out of the same material.
One way we already know Earth will affect Apophis is by changing its orbit. Currently, Apophis is categorized as an Aten-type asteroid, which is what we call the class of near-Earth objects that have a shorter orbit around the sun than Earth does. Apophis currently gets as far as 0.92 astronomical units (137.6 million km, or 85.5 million miles) from the sun. However, our planet will give Apophis a gravitational nudge that will enlarge its orbit to 1.1 astronomical units (164.6 million km, or 102 million miles), such that its orbital period becomes longer than Earth’s.
It will then be classed as an Apollo-type asteroid.
Ramses won’t be alone in tracking Apophis. NASA has repurposed their OSIRIS-REx mission, which returned a sample from another near-Earth asteroid, 101955 Bennu, in 2023. However, the spacecraft, renamed OSIRIS-APEX (Apophis Explorer), won’t arrive at the asteroid until April 23, 2029, ten days after the close encounter with Earth. OSIRIS-APEX will initially perform a flyby of Apophis at a distance of about 2,500 miles (4,000 km) from the object, then return in June that year to settle into orbit around Apophis for an 18-month mission.

Furthermore, the European Space Agency still plans on launching its Hera spacecraft in October 2024 to follow-up on the DART mission to the double asteroid Didymos and Dimorphos. DART impacted the latter in a test of kinetic impactor capabilities for potentially changing a hazardous asteroid’s orbit around our planet. Hera will survey the binary asteroid system and observe the crater made by DART’s sacrifice to gain a better understanding of Dimorphos’ structure and composition post-impact, so that we can place the results in context.
The more near-Earth asteroids like Dimorphos and Apophis that we study, the greater that context becomes. Perhaps, one day, the understanding that we have gained from these missions will indeed save our planet.
