As @NASAPersevere explores the surface of Mars, scientists hunting for signs of ancient life on the distant planet are using data gathered on a mission much closer to home - at a lake in southwest Turkey reut.rs/2O7fNAn
.@NASA says the minerals and rock deposits at Salda are the nearest match on earth to those around the Jezero Crater where the spacecraft landed and which is believed to have once been flooded with water
Information gathered from Lake Salda may help the scientists as they search for fossilized traces of microbial life preserved in sediment thought to have been deposited around the delta and the long-vanished lake it once fed
A team of American and Turkish planetary scientists carried out research in 2019 on the shorelines of the lake, known as Turkey’s Maldives because of its azure water and white shores
Scientists believe the sediments around the lake eroded from large mounds that are formed with the help of microbes and are known as microbialites.
The team behind the Perseverance rover wants to find out whether there are microbialites in Jezero Crater reut.rs/2O7fNAn

Health authorities in Denmark, Norway and Iceland suspended the use of AstraZeneca’s COVID-19 vaccine shots following reports of the formation of blood clots in some people who had been vaccinated reut.rs/38vNL8u 1/5
Austria earlier stopped using a batch of AstraZeneca shots while investigating a death from coagulation disorders and an illness from a pulmonary embolism 2/5
The European medicine regulator EMA said the vaccine’s benefits outweighed its risks and could continue to be administered. Europe is struggling to speed up a vaccine rollout after delivery delays from Pfizer and AstraZeneca 3/5
The COVID-19 vaccine from Pfizer and BioNTech was able to neutralize a new variant of the coronavirus spreading rapidly in Brazil, according to a laboratory study published in the New England Journal of Medicine reut.rs/3brKMjl
Blood taken from people who had been given the vaccine neutralized an engineered version of the virus that contained the same mutations carried on the spike portion of the highly contagious P.1 variant first identified in Brazil, the study found
The scientists said the neutralizing ability was roughly equivalent the vaccine’s effect on a previous less contagious version of the virus from last year.
The spike, used by the virus to enter human cells, is the primary target of many COVID-19 vaccines
A Dutch inventor has come up with what he hopes could be a potentially faster and easier method to screen for coronavirus infections: screaming 🗣️ reut.rs/3sJZsjq 1/4
Instead of unpleasant nasal swab tests, Peter van Wees asks participants to step into an airlocked cabin and to scream, or sing. An industrial air purifier collects all the particles emitted, which are then analyzed for the virus 2/4
Van Wees, a serial entrepreneur, has set up his booth next to a coronavirus testing center on the outskirts of Amsterdam to try his invention out on people who have just been tested 3/4
The majestic sight of elephants roaming beneath Mount Kilimanjaro has long lured throngs of wildlife-lovers to Amboseli National Park on Kenya’s border with Tanzania. Now, the free movement of the elephants may be under threat - from avocados reut.rs/3kHEsXZ 1/5
Kenyan agricultural company KiliAvo Fresh, which has farms near Amboseli on nearly 175 acres of land, is building nurseries and preparing to grow avocados, whose popularity is growing worldwide due to its high nutritional value. Conservationists are aghast 2/5
They say the plans and an electric fence on the farm will block the crucial Kimana Wildlife Corridor where elephants move between Amboseli, the Tsavo and Chyulu Hills parks, and strangle one of the region’s most beloved and important safari parks 3/5
🦇 As the @WHO reaches its findings on the zoonotic origins of the coronavirus, @jhjanicki and @SimonScarr explain why bats make such ideal hosts for disease-causing viruses tmsnrt.rs/382UG8Q
Bats are a group of flying mammals, with more than 1,300 species in 20 families. They make up approximately 20% of all mammal species and are found all over the world except for the Arctic, the Antarctic and a few oceanic islands 🥶 2/7
Authorities struggled to clear ice and fallen trees from the streets of Madrid, and temperatures in parts of Spain hit record lows after a snowstorm wrought havoc across the country on the weekend reut.rs/3bykpsk 1/5
Early jubilation at the historic snowfall, which saw skiers gliding through the streets and mass snowball fights, gave way to frustration as most public transport remained stalled and pedestrians avoided the icy streets 2/5
More than 800 soldiers have been deployed to help clear the city, where many roads are still blocked after Storm Filomena felled some 150,000 trees, cut supply lines and left supermarket shelves bare 3/5
