CNN —Archaeologists working deep in the Amazon rainforest have discovered an extensive network of cities dating back 2,500 years. The team also discovered monumental complexes with much larger platforms, which, they said, probably had a civic or ceremonial function. Even the most isolated complexes were linked by pathways and an extensive network of larger, straight roads with curbs. In the empty buffer zones between complexes, the team found features of land cultivation, such as drainage fields and terraces. These were linked to a network of footpaths, according to the study.

"The importance of the far side impact was to produce seismic waves that traversed the deep interior of the planet, including the core. Previously, we had not observed any seismic waves that had transited the core. Unlike Mars, Earth has no molten layer around its core. One of the two studies published on Wednesday indicates this layer is fully molten, with the other indicating that most of it is fully molten, with the top portion partially molten. "We have learned a lot about Mars by studying the unique seismic record provided by the InSight mission," Samuel said.

PARIS (AP) — The “Mona Lisa” has given up another secret. The oil-paint recipe that Leonardo used as his base layer to prepare the panel of poplar wood appears to have been different for the “Mona Lisa," with its own distinctive chemical signature, the team of scientists and art historians in France and Britain discovered. Gonzalez has studied the chemical compositions of dozens of works by Leonardo, Rembrandt and other artists. Political Cartoons View All 1206 Images“In this case, it’s interesting to see that indeed there is a specific technique for the ground layer of ‘Mona Lisa,’" he said in an interview with The Associated Press. “It flows more like honey.”But the “Mona Lisa” — said by the Louvre to be a portrait of Lisa Gherardini, the wife of a Florentine silk merchant — and other works by Leonardo still have other secrets to tell.

Fossils embedded in rock reveal intriguing details about animals, plants and other life-forms that once called Earth home. ConsequencesCrawford Lake in Ontario is the geological site that best reflects a new epoch recognizing the impact of human activity on Earth, said geologists of the Anthropocene Working Group. The Anthropocene Working Group determined in 2016 that the epoch began around 1950 — the start of the era of nuclear testing. The international research group says that Crawford Lake in Ontario best charts humanity’s impact on Earth. Back then, it took 10 hours to relay a single image to Earth — incredibly slow by today’s standards.

Explore the universe with news on fascinating discoveries, scientific advancements and more.CNN —Researchers using a cutting-edge technique have discovered hidden details in two ancient Egyptian paintings in the Theban Necropolis, near the River Nile, that date back more than 3,000 years. Using portable chemical imaging technology, the researchers identified alterations made by the artists that are rare in Egyptian paintings, commonly thought to be the product of highly formalized workflows. We want to understand how these paintings were made.”X-ray fluorescence in chemical imaging technology helps to reveal alterations made in Egyptian tomb paintings that may not seem obvious to the naked eye. “It demonstrates the potential value of quantitative data, obtained through scientific analysis, for a more comprehensive and less subjective interpretation of ancient Egyptian art,” she said. “And the adaption of portable (X-ray) instruments as mobile devices designed for use in the field is a very exciting advancement in the study of ancient Egyptian wall paintings.”

☆ World’s oldest architectural plans date from the Stone Age

CNN —Archaeologists working in Saudi Arabia and Jordan say they have discovered the oldest known architectural plans. The Stone Age hunting traps date back about 9,000 years and are known as kites because of the shape they form. Archaeologists are shown during the discovery of the kite engravings at Jebel az-Zilliyat in Saudi Arabia. Engravings made to scaleThe engraved stone is shown at the JKSH F15 site in Jibal al-Khashabiyeh in Jordan. His colleagues in Saudi Arabia unearthed a larger engraved stone in the region of Jebel az-Zilliyat that was almost 4 meters (13 feet) long.

☆ Carnivorous plants may lure their insect prey with specialized scents

CNN —Sarracenia pitcher plants, found in bogs throughout eastern North America, look like trumpet-shaped flowers, often in purplish or reddish hues. Different kinds of Sarracenia pitcher plants tend to eat different kinds of insects — some species trap more ants, while others feast on bees and moths. But recently opened pitcher plants that don’t stink of rotting bug carcasses provide an opportunity to identify the scents, she explained. The biggest challenge with the study, honestly, is that they did it in France,” rather than in the Sarracenia pitcher plants’ native North American bogs. It’s important to study pitcher plants due to the unique role they play in their increasingly fragile ecosystems, he added.

☆ Data released by China suggests COVID-19 virus may have come from raccoon dogs and 'strengthens' Wuhan wet-market theory

Newly released genetic data from Wuhan has found raccoon dog DNA blended with the COVID-19 virus. Since the first COVID-19 death in Wuhan on January 11, 2020, the virus has killed 6,873,477 people worldwide. This suggests that the virus may have infected the animals, according to the scientists. "We continue to call on China to be transparent in sharing data and to conduct the necessary investigations and share the results. Since the first COVID-19 death — which was recorded in Wuhan, China, on January 11, 2020 — the virus has killed 6,873,477 people around the world, according to WHO data.

Вопрос о естественном или синтетическом происхождении SARS - CoV -2 нельзя ставить в зависимость от политической повестки дня или коммуникационной стратегии. Тем не менее, вывод Люка Монтанье основан на серьезном наблюдении, которое важно для понимания механизма заражения SARS - CoV -2. Остается четвертая вставка , которая образует сайт расщепления фуриновой протеазой в SARS - CoV -2, не обнаруженный в других вирусах семейства SARS - CoV . Их результаты показывают, что три из четырех вставок, наблюдаемых в SARS - CoV -2, могут быть обнаружены в более старых штаммах коронавируса. Считаю необходимым подчеркнуть, что и концепция Мечникова, и концепция Эрлиха — это достижения начала ХХ века, что нас от этих замечательных достижений отделяет уже более одного столетия.

☆ Ежегодно на Землю падает более 5000 тонн внеземной пыли
▼ + stars: | 2021-05-10 | by ( Mld Media Srl | ) noi.md time to read: +2 min

Эти частицы пыли межпланетного происхождения проходят сквозь нашу атмосферу и наблюдаются в ней как «падающие звезды». Некоторые из таких частиц достигают поверхности Земли в форме микрометеоритов. В новом исследовании ученые международной программы, проводимой на протяжении более чем 20 лет, определили, что примерно 5200 тонн таких микрометеоритов достигает поверхности планеты ежегодно. Если применить полученные командой результаты ко всей планете, то общий годовой поток микрометеоритов составляет 5200 тонн. Сравнение потока микрометеоритов с теоретическими прогнозами подтверждает, что источниками большинства микрометеоритов, достигающих Земли, являются кометы (80 процентов), а остальная пыль является продуктом фрагментации астероидов, добавили авторы.

☆ Studiu: Perioada în care Alpii sunt înzăpeziţi s-a redus cu aproape o lună în ultimii 50 de ani

Acest studiu ''oferă o imagine de ansamblu asupra tendinţelor climatice asociate stratului de zăpadă'', a explicat Samuel Morin, cosemnatar şi director al Centrului Naţional de Cercetări Meteorologice (Météo France/CNRS). Reducerea observată a stratului de zăpadă în munţi este o ''tendinţă de fond, care confirmă studiile anterioare'', efectuate la nivel local sau naţional. ''Dispunem cu adevărat de o analiză globală a stratului de zăpadă la scara Alpilor în ansamblu'', a rezumat cercetătorul. Constatările lor sunt clare: stratul de zăpadă s-a redus în Alpi. Pe întreg parcursul sezonului, adâncimea medie a stratului de zăpadă de la atitudini cuprinse între 1.000 şi 2.000 de metri în nordul Alpilor s-a redus cu 2,8 centimetri pe an.
