Egg yolk precursor protein regulates mosquitoes’ attraction to humans

Posted by in category: biotech/medical

Feeding mosquitoes sugar makes them less attracted to humans, a response that is regulated by the protein vitellogenin, according to a study publishing May 9 in the open-access journal PLOS Biology by Jessica Dittmer, Paolo Gabrieli and colleagues at the Università degli Studi di Pavia in Italy.

Female mosquitoes must feed on blood to provide energy and nutrients for their developing eggs, but they can also supplement their diet with sugars by drinking plant nectar or sap. The team fed young female tiger mosquitos (Aedes albopictus) sugar solutions, and found it reduced their attraction to . Female energy levels constantly increase after feeding sugars, and they are not related to the insects’ motivation to find a host.

Transcriptome sequencing revealed a wave of gene expression changes associated with this reduction in host-seeking behaviour, which affected at least 23 genes including the vitellogenin gene Vg-2—known to play a role in ovary development. RNA interference experiments to knockdown the Vg-2 gene expression restored the mosquitos’ attraction to humans, confirming the gene’s key role in regulating feeding behaviour.

Antibiotics and Vitamin C Halt Cancer Growth

Posted by in category: biotech/medical

A new open-access study from researchers at the Biomedical Research Centre in the United Kingdom shows how two antibiotics and Vitamin C can be combined to suppress cancer stem cells (CSCs) of the breast [1].

While antibiotics are not normally effective against cancer, and Vitamin C is more well-known for its role in supporting the immune system, this combination has been shown to attack cancer stem cells through a combination of mitochondrial suppression and oxidative attacks on the mitochondria, thus causing mitochondrial growth to falter.

Cyberpunk Jacket Is The Garment of Choice For The Streets of 2019

Posted by in categories: futurism, transportation

Fans of science fiction and related genres have always been disappointed by real life. The future holds so much promise on paper, yet millions were disappointed upon reaching 2015 to find that hoverboard technology still eluded us. It’s not all bad, though – [abetusk] has developed a cyberpunk jacket so you can live out your grungy hacker fantasies in real life.

The effect is achieved with specially designed jacket patches. Nylon fabric is lasercut with artwork or lettering, and then placed over an electroluminescent panel. The fabric acts as a mask and is glued onto the EL panel, and the assembly is then attached to the back of the jacket with velcro.

We Were Really Overdue For Laser Jackets

Posted by in categories: computing, media & arts, neuroscience, surveillance

Depending on who you talk to, everything is either fine, or we’re living in an oppressive cyberpunk dystopia in which we forgot to drench everything in colored neon lighting. There’s little to be done about the digital surveillance panopticon that stalks our every move, but as far as the aesthetic goes, [abetusk] is bringing the goods. The latest is a laser jacket, to give you that 2087 look in 2019.

The build starts with a leather jacket, which is festooned with 128 individual red laser diodes. These are ganged up in groups of 4, and controlled with 32 individual PWM channels using two PCA9685 controllers. An Arduino Nano acts as the brains of the operation, receiving input from a joystick and a microphone. This allows the user to control lighting effects and set the jacket to respond to sounds and music.

Color-Changing “Smart Thread” Turns Fabric into a Computerized Display

Posted by in category: computing

But who would wear clothes that double as a computer display? And why? And how would people respond to computerized clothes? The team explored these questions in in-depth research sessions with seventeen people, including five fashion designers.

At first the participants were put off by thinking of Ebb as another computer screen. “I don’t want to wear a screen,” said one participant. “There’s enough glare in my life as it is,” said another. The idea made them recall past experiences of light-emitting clothing: “blinking Christmas sweaters, children’s sneakers that lit up when they walked, or light-up visors they might get at carnivals and amusement parks.”

But Ebb isn’t a light-up screen; it’s just fabric that changes color. Feeling the fabric samples changed their responses. One participant said that the fabric “seems a lot more tactile and something like cloth rather than plasticky… I think it’s just more intimate and easier to like.”

A pathogen is destroying Italy’s olive trees

Posted by in categories: biotech/medical, business

Olive trees don’t just dot the landscape in Puglia, Italy; they define it. They are so important here, in the heel of Italy’s boot, that locals use words like “patrimony” and “cultural heritage” when describing them. But what is worrying olive growers here is a disease that’s killing olive trees by the millions.

Paul Cappelli, who’d been an advertising executive in New York City until a few years ago, left his job and moved to a home on the ancient Appian Way surrounded by olive trees, and entered the oil business. “Not the Texas oil business; I’m in the real oil business!” he said.

Today, Villa Cappelli produces about 10,000 liters of olive oil, 95 percent of it sold in the U.S.

Digital Paper Could Probably Be Alternative After France Banned Tablets in Schools

Posted by in categories: education, government, law, mobile phones, policy

From the beginning of the year 2019, the sales of Boox eReaders slightly increase, and so do many other brands such as Kindle, Kobo and Sony. All of them suffered a rapid drop in sales in the previous year but now they are getting back. This may cause by the event that France prohibits students from using smartphones and tablets in schools.

Digital Paper Could Probably Be Alternative After France Banned Tablets in Schools

Under the legislation passed in 2018, the French students as old as 15 were not allowed to bring their smartphones as well as tablets to schools from September. The law was originally noted in President Emmanuel Macron’s election campaign. Now, one semester has gone, actually what do folks think to this policy? Earlier than that, France endorsed a blanket smartphone ban for drivers, even those who park at the side of the road, so the further action to school is not that surprising. It seems that the French government is getting realized that the control of electronics use is significant to beat back the encroachment of digital technology in everyday life.
