Dengue virus makes mosquitoes bite more – Magic Mistura を

The disease is caused by the DENV virus, which is transmitted by the mosquito Aedes aegypti – he acquires the virus by biting an infected person, and transfers it to others by biting them. This is the cycle of the disease, known for decades.

The novelty, as revealed by a study published by scientists from France and Singapore (1), is that DENV is able to alter the behavior of the mosquito, causing it to bite more often and look for more victims – and thereby spread the virus more.

The researchers put two groups of mosquitoes in contact with laboratory mice, filmed and analyzed their behavior. The Aedes infected with DENV attacked more mice than uninfected mosquitoes, and the presence of the virus also hindered blood sucking – causing mosquitoes to bite each animal more often to obtain the same amount of it. The study calculated that these two changes increase the capacity of each mosquito to transmit the virus by 300%.

Plenty of Money, No Conscience

Filosofa's Word

I have never been a fan of Elon Musk, but then I’m not a fan of wealthy people who waste their wealth on frivolous ‘toys’ rather than helping people in need.  I see them as people without conscience, without a sense of social responsibility.  Well, as Dan Rather shows us in an email I received yesterday, Mr. Musk has proven what sort of person he is …


This is Not Okay

Dan Rather and Elliot Kirschner

This won’t take long. Because there’s not much to say.

It involves something that went out earlier today on Twitter, that social media platform that limits thoughts to 280 characters and can be both inspirational and a cesspool. One user who tends to wade into the latter is the tech billionaire Elon Musk, who posted and then deleted a Tweet that created quite a stir. That he eventually removed his Tweet is welcomed, but…

Istorijsko jezgro Talina, Estonija – Tallinn Historic Center, Estonia

Myrela

S visinom od 46 metara Kiek in de Kök najviša je kula na talinskim odbrambenim zidinama. Njeno ime doslovno znači “gvirenje u kuhinju” jer se, po predanju, kroz ureze u zidovima moglo krišom posmatrati šta jedu stanari kule. Sjeverni ulaz u grad zaštićen je zdepastom kulom poznatom kao “Debela Margareta” (Paks Margareta). Do Gornjeg grada (Toompea) može se stići putem Dugačka noga (Pikk Jalg) što se postepeno penje prateći liniju zidova. Moguće je ići i kraćim, ali težim putem koji se zove Kratka noga (Lühike Jalg). Ova imena primjer su estonskog smisla za humor koji im je pomogao da prežive razna osvajanja što su obilježila njihovu istoriju.

Prvi zapisi o Talinu potiču od arapskog geografa El Ibrisija koji je 1154. godine obilježio na mapi mjesto Kvaleveni, na današnjoj lokaciji grada. Ime Kvaleveni potiče od Kaleva, legendarnog junaka koga Estonci smatraju svojim osnivačem…

An article about Black Inventors

Ospreyshire's Realm

https://getpocket.com/explore/item/america-s-always-had-black-inventors-even-when-the-patent-system-explicitly-excluded-them?utm_source=pocket-newtab

I thought I should have a post for Black History Month, so I thought I would share a link with you. There have been so many African-American inventors that people haven’t heard of. Sadly, you had inventions stolen by the dominant society even after slavery. There have been so many inventions like cotton scrapers, folding beds, yellow traffic lights, filaments, moving blood banks, and video game cartridges to name a few. Feel free to check out the article.
