Scientists Warn Virus Could Cause Heart Disease In Adults

Scientists Warn Virus Could Cause Heart Disease In Adults

The risk of heart attack is increased by the virus, spread through bodily fluids 

New research suggests that a common infection affecting 60 to 99 per cent of adults could result in high blood pressure and hardening of the arteries – leading causes of heart disease, stroke and kidney disease.

How Microbes Can Fuel America In The Future

How Microbes Can Fuel America In The Future 

Scientists Use Tiny Organisms to Create Fuel, Viruses to Make Batteries

For millenniums, microbes have been a staunch technological ally. They have leavened our bread and cured our cheeses. Now, engineers are asking them to convert carbon dioxide into fuel and to build a new generation of batteries. Some of the smallest life forms with which we share the planet are helping us cope with the energy challenges of the 21st century.

Tobacco Plants Genetically Modified To Produce Medicine

Genetically modified tobacco plant 

Tobacco isn’t famous for its health benefits. But now scientists have succeeded in using genetically modified tobacco plants to produce medicines for several autoimmune and inflammatory diseases, including diabetes. The research is published in the open access journal BMC Biotechnology.

Instant Immunity From A Vaccine

Instant Immunity From A Vaccine

 

A new approach primes antibodies to instantly attack cancers, HIV, and other diseases.

The body’s immune system is often likened to an army, and vaccines to training exercises that build up defenses against pathogens. By exposing the immune system to inactive forms of a virus or bacteria, a vaccine trains antibodies to fight off a real pathogen in the event of an invasion. However, while vaccines prepare antibodies to identify an attacker, they often don’t give specific instructions on exactly how to bring it down. Some antibodies may successfully hit a pathogen’s weak spot, while others may miss the mark entirely. That’s part of the reason why it normally takes several weeks or months for some vaccines to build up an effective immune response.

Sick Traveler Detector

Sick Traveler Detector 

If you thought the airport denizens of the TSA were already obnoxious, wait until they get their mitts on a Sick Traveler Detector. It’s a software idea by Belgian company Biorics, which can determine if travelers are sick by the sound of their coughs. If you frequently get sick after flying, you might welcome such an intrusive technique that singles out hacking, virus-spreading passengers.

Why Are A Majority Of People Resistant To Cancer?

Why Are A Majority Of People Resistant To Cancer? 

 Dividing cancer cells

Every year, millions of people are diagnosed with cancer – a remarkably high number. But what about the flipside of those statistics? That is, two out of three people never get cancer, and more than half of heavy smokers don’t get cancer, either. A recent study points out this overlooked fact, and suggests that researchers might discover something by asking why so many people are resistant to the often deadly disease.

Evolving Viruses To Death

Even Viruses Can’t Escape Evolution

Evolution, by the very meaning of the word, is generally thought to be a process that slowly unfolds over time, without outside interference.

But now scientists from Rice University are trying to force certain viruses to evolve erratically, in an attempt to kill them. The technique is called “lethal mutagenesis,” and while it may sound vicious, it could be a last resort of self-defense against contagious viruses that attack humans.

Credit: Graham Colm.Rice bioengineer Michael Deem explains that genetically engineering a virus to mutate in a specific way could change entire sets of the organism’s genes. In their recent study, the Rice scientists develop a formula that can be used to predict exactly how certain mutations alter evolution.
