In the earliest days of the most recent Zika virus pandemic, researchers around the world set out to understand every facet of a contagion that seemed almost uncontrollable. While some researchers and physicians studied the pathophysiology of the virus and the seemingly minor illness it caused, ecologists and entomologists sought out the virus’s origin and […]

Zika epidemic will end in three years, study suggests

Posted on Leave a commentPosted in Biomedical Science, Biotechnology, Diagnostics, Epidemiology, Immune System, Medical News, Mental Health, Microscopy, Nervous System, Neurology, Parasites, Pioneering Technology, Viruses

The current Zika epidemic is likely to end within three years because there will be too few people left to infect, a team of scientists is predicting. Writing in the journal Science, they said this could lead to a gap of 10 years before the next epidemic. The Imperial College London team created a model […]

Researchers at the University of Wisconsin-Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti, the mosquito species responsible for passing the virus to humans. A strain of Aedes aegypti mosquitos feed from a membrane of blood in Matthew Aliota’s research lab insectary. Credit: Jeff Miller […]

Herpesviruses could be eradicated with gene-editing technique

Posted on Leave a commentPosted in Biomedical Science, Biotechnology, Dermatology, DNA, Genetics, Immune System, Medical News, Microscopy, Pharmaceuticals, Viruses

Herpesviruses are responsible for an array of infections and diseases, including cold sores, shingles, genital herpes, and even some forms of cancer. Now, new research reveals how a revolutionary genome-editing technique called CRISPR/Cas9 could eliminate these viruses once and for all. Researchers say the CRISPR/Cas9 gene-editing tool shows promise for the elimination of herpesviruses. Study […]

The US Food and Drug Administration (FDA) has approved the first human tests of an experimental Zika virus vaccine, the makers of the drug announced on Monday. https://d1o50x50snmhul.cloudfront.net/wp-content/uploads/2016/02/f0127511-zika_virus_in_blood_illustration-spl-1200×800.jpg Called GLS–5700, the medication will be used in a clinical trial involving 40 healthy people, and represents the first major step towards ultimately immunising people against Zika […]

Zika: portable, rapid diagnostic test could reach clinical use in months

Posted on 1 CommentPosted in Biomedical Science, Biotechnology, Diagnostics, Epidemiology, Immune System, Medical Advice, Medical News, Neurology, Parasites, Pharmaceuticals, Pioneering Technology, Vaccines, Viruses

A fast, portable test for Zika virus could be in the cards, according to a new study published in Cell, which details how a prototype device was able to accurately detect the virus in the blood and saliva of infected monkeys. Zika virus is primarily spread to humans through the bite of an infected Aedes […]

Can ‘sweaty billboard’ help fight Zika virus?

Posted on Leave a commentPosted in Biotechnology, Epidemiology, Medical News, Parasites, Pharmaceuticals, Pioneering Technology, Viruses

A billboard that attracts and kills mosquitoes has been designed by marketing agencies in Brazil. The board releases a mixture of a lactic acid solution that mimics the smell of human sweat and carbon dioxide, which is in human breath.   The Mosquito Killer Billboard   Its inventors have released the blueprint for free and […]

A research team led by the University of Leeds has observed for the first time how HIV and Ebola viruses attach to cells to spread infection. Quantum dots are fluorescent crystals in which the color of the emitted light is dependent on the size of the crystal. Credit: Richard E. Cruise, University of Leeds The […]

A Potential HIV Cure: Removing HIV DNA From Immune Cell Genome Prevents Reinfection

Posted on Leave a commentPosted in Biomedical Science, DNA, Genetics, HIV, Immune System, Medical News, Viruses

In the past four years we’ve heard stories of babies born with HIV who were reportedly cured, only to have the disease return months later. In an effort to find a cure for HIV/AIDS and bring the epidemic to an end, scientists at Temple University have designed a specialized gene editing system that could pave the way to an eventual cure. http://blogs.elca.org/hungerrumblings/files/2011/06/hiv-virus.gif […]

First Human Test of Optogenetics Could Restore Sight to the Blind

Posted on Leave a commentPosted in Medical News, Viruses

A decade-old technique that allows researchers to control brain function in lab animals could partially restore sight to the blind. In a trial sponsored by RetroSense Therapeutics, a startup company in Ann Arbor, Michigan, doctors will inject a harmless virus loaded with DNA from photoreceptive algae into the eyes of 15 patients suffering from retinitis pigmentosa. The experimental procedure represents the first human […]

Virginia Tech scientist finds way to potentially track and stop viruses

Posted on Leave a commentPosted in Medical News, Viruses

Viruses are molecular thieves that take from their hosts under the cloak of darkness. But now a Virginia Tech scientist has found a way to not only track viral hijackers, but also potentially stop them from replicating. The discovery has broad ranging applications in stopping viral outbreaks such as Hepatitis C in humans and a […]

Genetically Modified Mosquitoes to Fight Zika?

The goal: Sterile males would mate with females that carry the germ suspected of causing birth defects  As the Zika virus continues to spread fear and potentially devastating health problems throughout Latin America and the Caribbean, scientists are weighing the use of a controversial weapon – genetically modified mosquitoes.  The mosquito-borne Zika virus is thought – but […]

Are Infectious Disease Outbreak Films Scientifically Accurate?

Posted on Leave a commentPosted in Epidemiology, Medical News, Viruses

Dead bodies strewn throughout the streets, cities engulfed in widespread hysteria. Disease is spreading, and humans, for perhaps the first time, begin to realise they were just placed on the endangered species list. Scenes like this can be found in most films that depict an infectious disease outbreak. Viewers love them because they represent a […]

Giving healthy gay men HIV drugs ‘could help reverse epidemic’

Posted on Leave a commentPosted in HIV, Medical News, Viruses

Giving daily HIV drugs to healthy gay men has huge potential to help reverse the epidemic, say scientists. The medication prevents new infections by killing the virus before it has a chance to take hold in the body. Calculations, published in the Lancet, indicate giving the drugs to the most at-risk men could cut new […]

State of emergency declared as Brazil faces virus that shrinks babies’ brains

Posted on Leave a commentPosted in Epidemiology, Medical News, Viruses

And it’s spreading quickly through neighbouring countries. Between 2014 and 2015, Brazil has seen the number of babies born with microcephaly – a rare and devastating neurological disorder that causes newborns to develop abnormally small skullsand brains – increase dramatically, from 200 to nearly 3,000. Brazil’s worst affected regions have declared a state of emergency, and health officials […]
