Now scientists say skeletal remains found in a well at Norway’s Sverresborg castle belong to the mysterious figure mentioned in a medieval saga. "If one would anticipate to finding historical accuracy in some sagas, Sverris Saga would be the best contender." Recent scientific developments provide a range of advanced methods to analyze skeletal remains in greater detail, such as genetic sequencing and radiocarbon dating. via iScienceAdvancements in technology also allow skeletal remains to be linked to characters from Norse sagas, blurring the lines between legendary myths and historical facts. And this is not the first instance of a saga character’s skeletal remains being found.

CNN —Researchers have connected the identity of skeletal remains found in a well at Norway’s Sverresborg castle to a passage in a centuries-old Norse text. The text is rich in detail, including full names, locations, battles and military strategy as well as Sverre’s speeches. For the latest study, Martin and his colleagues wanted to bring together historical, archaeological and genetic context for Well-man’s remains. Excavations in 2014 and 2016 unearthed more of Well-man's remains, including his skull.

“The study also shows that food contact materials can contain mutagenic chemicals that harm our DNA, such as heavy metals,” Wagner said. Another chemical group in food packaging that has migrated into people is phthalates, the research revealed. “We’ve got, say, 60 years of research into the migration of chemicals into food from food processing and packaging equipment. “Given that there are (tens) of thousands of food contact chemicals, biomonitoring programs do not have the capacity to test for all chemicals we are potentially exposed to,” Wagner said. “However, there are also important gaps that need to be addressed as we undertake the work to strengthen our food chemical safety activities,” he said.

☆ Bones discovered in Spanish cave likely belong to famed priest who created popular pilgrimage

Remains found in a tomb in northwestern Spain are likely to belong to a ninth-century bishop believed to have helped create the Camino de Santiago, one of Christianity’s most popular pilgrimages, a new study has found. News of the discovery reached King Alfonso II of the neighboring region of Asturias, who marched with his court from Oviedo to Santiago. The 90 mile royal pilgrimage established what is today known as the “Primitive Way”, the oldest path used by pilgrims of the Camino, or Way of St. James. Theodomir’s existence had been hotly debated until 1955, when Spanish archaeologist Manuel Chamoso Lamas discovered a tombstone underneath Santiago de Compostela’s cathedral inscribed with his name. Perez-Ramallo told El Pais newspaper that there was a “98% likelihood of it being Theodomir.”

☆ 16,000 plastic chemicals exist, many of them hazardous and unregulated, report says

And with new plastic chemicals entering the market all the time, it’s been difficult for regulators and policy makers to determine the scope of the problem. Now, for the first time, researchers have pulled together scientific and regulatory data to develop a database of all known chemicals used in plastic production. It’s a staggering number: 16,000 plastic chemicals, with at least 4,200 of those considered to be “highly hazardous” to human health and the environment, according to the authors. Although grouping would capture about 1,000 of the most toxic chemicals in plastics, Wagner said, that still leaves about 2,600 chemicals that still need to be regulated. Missing hazard dataIn addition to the massive number of toxic chemicals, the report found that detailed hazard information is missing for more than 10,000 of the 16,000 chemicals.

☆ Some Whales May Have Been Wiped Out by Medieval Europeans

Industrial-scale whaling in the 19th and 20th centuries nearly drove many whale species into extinction. But it turns out that whaling’s effects on where whales live go back much deeper into human history. As early as 8,000 years ago, humans carved their attempts to capture whales into South Korean cliffs. More recently, medieval texts described the whaling preferences of Europeans. So he and his colleagues examined 719 pieces of whale bones collected at archaeological sites from Norway to Portugal.

☆ Found Norway shipwreck could be up to 700 years old

CNN —Resting at the bottom of Mjøsa, the largest lake in Norway, a shipwreck from hundreds of years ago is in almost perfect condition, frozen in time. The lake is a source of drinking water for about 100,000 people in Norway, according to the Norwegian University of Science and Technology, so the munitions posed health risks. Since the shipwreck was found in the middle of the lake, Ødegård believed the ship had gone down in bad weather. It’s most likely that the ship used square-shaped sails, he added, that proved to be difficult to navigate for seafarers caught in extremely windy conditions. The nearly 2,200-year-old shipwreck was relatively well preserved for being thousands of years old.

☆ Frozen embryos linked to increased risk of hypertensive disorders during pregnancy, study finds

Undergoing in vitro fertilization using frozen embryos is linked to a greater risk of hypertensive disorders, including preeclampsia, during pregnancy, according to research published Monday in the journal Hypertension. Overall, the risk of hypertensive disorders was low: about 7.4% in women who used frozen embryos, compared with 5.6% in women who used fresh embryos and 4.3% for women who conceived naturally. In addition, they found, there was no significant difference in risk between the women who conceived naturally and those who did IVF using fresh embryos. The group included 4.4 million naturally conceived pregnancies and compared them to just over 78,000 IVF pregnancies conceived using a fresh embryo and about 18,000 using a frozen embryo. Petersen emphasized that the overall risk for preeclampsia was still low and that the results of the new study should not scare women away from using frozen embryos.

☆ O lucrare științifică din cadrul UTM, publicată în cea mai prestigioasa revistă, Advanced Materials Technologies

Lucrarea reprezintă o investigație a influenței protecției suprafeței nanocoloanelor de ZnO asupra performanțelor de detectare a gazelor în medii cu umiditate relative înaltă. În lucrare, peliculele columnare nedopate și dopate (ZnO: Sn, ZnO: Fe, ZnO: Ag și ZnO: Cu) sunt acoperite cu un strat ultra-subțire de SiO 2 (10-20 nm). Rezultatele obținute arată o imunitate ridicată a proprietăților de detectare a probelor acoperite cu SiO 2 la umiditate. Mai mult, măsurătorile de detectare a gazelor arată că pierderea răspunsului după 203 zile este semnificativ mai mică pentru probele acoperite, indicând o stabilitate mai mare a performanței de detectare. Calculele arată legarea puternică a speciilor de apă pe stratul de SiO 2 indicând absorbția preferențială a moleculelor de apă pe SiO 2 .
