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.

This date dramatically pushed back the timeline of humans’ history in the Americas, the last landmass to be settled by prehistoric people. National Park ServiceHowever, some archaeologists questioned the age of the footprints established by those initial findings.

Nor, despite advances in genetic evidence, is it clear whether one or many populations of early modern humans made the long journey.

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.
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.
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 .
