The amount of heat-trapping carbon dioxide in the atmosphere has shot past a key milestone—more than 50% higher than pre-industrial times—and is at levels not seen since millions of years ago when Earth was a hothouse ocean-inundated planet, federal scientists announced Friday.
The National Oceanic and Atmospheric Administration said its long-time monitoring station at Mauna Loa, Hawaii, averaged 421 parts per million of carbon dioxide for the month of May, which is when the crucial greenhouse gas hits its yearly high. Before the industrial revolution in the late 19th century carbon dioxide levels were at 280 parts per million, scientists said, so humans have significantly changed the atmosphere. Some activists and scientists want a level of 350 parts per million. Industrial carbon dioxide emissions come from the burning of coal, oil and gas.

С 23 мая по 12 июня 2022 года по инициативе Министерства здравоохранения Республики Беларусь в стране проводится республиканская информационно-образовательная акция «Беларусь против табака» в рамках Всемирного дня без табака.
Всемирная организация здравоохранения (далее – ВОЗ) объявила о проведении глобальной кампании по случаю Всемирного дня без табака 2022г. на тему «Табак – угроза нашей окружающей среде». Эта кампания направлена на повышение осведомленности общественности в отношении воздействия табака во время его выращивания, производства и распространения, а также его отходов на окружающую среду. Для лиц, употребляющих табак, это станет еще одной причиной для отказа от табака.

With the help of the CRISPR/Cas molecular scissors, genetic information in a plant can be modified to make the latter more robust to pests, diseases, or extreme climatic conditions. Researchers have now developed this method further to eliminate the complete DNA of specific cell types and, thus, prevent their formation during plant development. This will also help researchers better understand development mechanisms in plants.

Nearly 15 million more people died during the pandemic than would have in normal times, the World Health Organization said on Thursday, a staggering measure of Covid’s true toll that laid bare how vastly country after country has undercounted victims.
In Mexico, the excess death toll during the first two years of the pandemic was twice as high as the government’s official tally of Covid deaths, the W.H.O. found.
In Egypt, excess deaths were roughly 12 times as great as the official Covid toll.
In Pakistan, the figure was eight times as high.
Those estimates, calculated by a global panel of experts assembled by the W.H.O., represent what many scientists see as the most reliable gauge of the total impact of the pandemic. Faced with large gaps in global death data, the expert team set out to calculate excess mortality: the difference between the number of people who died in 2020 and 2021 and the number who would have been expected to die during that time if the pandemic had not happened.

 Researchers have enabled a non-verbal person with an advanced degenerative disease to communicate with the aid of two brain implants.
The findings of a two-year clinical study, published in the journal Nature Communications on Tuesday, suggest that communication with patients who are completely paralyzed with amyotrophic lateral sclerosis (ALS) is possible.
ALS, also known as Lou Gehrig's disease, is a progressive neuromuscular condition that causes patients to lose motor function. While ALS is relatively rare, the number of people with the condition globally is increasing, with more than 300,000 people projected to be living with the disease by 2040. There is currently no cure for ALS.
