Назван неожиданный «убийца» сигнала Wi-Fi в доме
https://hi-tech.mail.ru/news/100910-nazvan-neozhidannyij-ubijtsa-signala-wi-fi-v-dome/
Металлические вещи и конструкции могут препятствовать прохождению сигнала Wi-Fi, если они расположены на пути между вашим маршрутизатором и гаджетом. Еще слабый сигнал часто объясняется удаленностью роутера от устройства и недостаточной мощностью передачи данных.

study shows that among climate-related causes, the redistribution of groundwater actually has the largest impact on the drift of the rotational pole."
What's more, the extracted groundwater that ended up in the oceans may have boosted global sea level rise by around 0.25 inch (6.24 millimeters). "Groundwater depletion is a significant contributor to sea level rise," the researchers wrote in the study, published June 15 in the journal Geophysical Research Letters.

Y Why curly hair was an evolutionary advantage

"Three wigs were made from black human hair sourced from China—one straight, one moderately curly, and one tightly curled—so that the researchers could observe how different hair textures affected heat gain and loss on the scalp. They also calculated heat loss at different windspeeds, after wetting the wigs to simulate sweating.

“Sweating isn’t free—you’re losing water and electrolytes. And for our hominin ancestors that could have been important.”

Y Why is India dropping evolution and the periodic table from school science?

Alternative methods
Moreover, there’s a great deal of literature and teaching practice that outlines how scientific concepts can be taught using visual methods, such as videos and animation, instead of by rote learning. An alternative is to embed concepts using non-fiction narrative storytelling. In the case of the periodic table, this would involve detailing how individual elements found their places in the table; the highs and lows, dramas and inflection points as researchers sought to get to the truth and be recognized for their achievements.

Few people would take issue with its ambition to boost critical thinking and promote learning by doing, or with its desire for students to enjoy their education. Both can go hand-in-hand with exploring India’s rich pre- and postcolonial history of discovery and innovation.
