Iowa high school senior Dasia Taylor has invented color-changing sutures that can catch an infection early.

Even if the interstellar object known as Oumuamua were an interstellar lightsail, it could never travel fast enough to be practical, says a new paper.

Your genes may have more influence than anything you put into your body when it comes to how iron relates to longevity. Here’s what you need to know.

The recent announcement that scientists have made human-monkey embryos and cultured them in the lab for two weeks made international headlines.

The technology to make animals that contain cells from other species has been available for decades and used extensively in research. These organisms are called “chimeras”.

But this latest advance highlights the need to broaden the discussion around the possible benefits of such research and, specifically, how inter-species chimeric research should be conducted in future.

It’s that time of year where the federal holiday in the United States commemorating the Declaration of Independence of the United States, (on July 4, 1776) is celebrated. To all my American fans I hope you have an awesome day! To celebrate I’m listing my favorite superheroes to rock the “Red, White and Blue”.

Happy Independence Day (Fourth of July)!

The adhesion and colonization or biofilm formation include primary stage in bacterial infections. Major adhesion virulence factors in this step include type I fimbriae (FimH) and pilli structures for attachment to the host cells^7,8. Furthermore, numerous bacteria secrete toxins and extracellular enzymes which play a crucial role in the apoptosis or necrosis of epithelial cells or immunocytes. Various virulence factors of A. baumannii such as adhesins genes like kpsMII (group 2 capsule synthesis) and fimH, tratT (serum resistance associated), fyuA (yersiniabactin receptor) and iutA (aerobactin receptor) have been investigated previously^9,10. An important polysaccharide for biofilm formation is encoded by pgaABCD locus¹¹. Biofilm production is a strategy to escape from harsh conditions and immune responses, hence play as reservoirs for drug-resistant systemic infections. Biofilm-producing A. baumannii has been isolated from several infectious origins such as pneumonia and devise-associated infections. Bacterial within biofilm can resist significantly more against antibiotics compared to planktonic mode of growth¹². Hence, biofilm-mediated infections are in relapse more frequently¹³.

Therefore, there is an urgent need to enhance the effects of antimicrobials against pathogenic bacteria. In recent years, interest has enhanced towards application of nanoparticles as therapeutic regimens^{14,15,16,17,18,19,20,21}. Silver nanoparticles (AgNPs), which have low toxicity in ecosystems and have high rate of surface capacity, can inhibit accumulation of biofilm materials responsible for evasion and protection^22,23,24.

The aim of this study was to isolate A. baumannii from wound infections, determine their resistance and virulence profile, and assess the impact of AgNPs on the bacterial growth, virulence and biofilm-related gene expressions in the isolated strains.

Gas taxes are the largest source of funding for highway construction, maintenance.

A new topic a new challenge for future civilizations.

I won’t write an introduction I will ask couple of questions to make you think about it.

Android malware known as FluBot is continuing to cause mayhem across some European countries, and there is speculation that the threat actors behind it may decide to target other geographies, including the United States. Here’s why you should be vigilant, how FluBot operates, and how you can remove this Android nasty from your device.

It’s also worth noting that this advice will help you stay safe from other Android malware strains. In recent days, cybercriminals have begun to target Europeans with TeaBot (also known as Anatsa or Toddler), an Android malware family that uses exactly the same technique as FluBot to spread and to lure users into giving up their sensitive data. FluBot and TeaBot are detected by ESET products as variants of the Android/TrojanDropper. Agent family.
