Unseen Armies Of Viruses And Bacteria Battle In The Deep
2014-05-02 03:58:44

National Science Foundation More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war. Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells. Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur...

Enzyme's double-edged sword may soon be sheathed Johns Hopkins biochemists have figured out what is needed to activate and sustain the virus-fighting activity of an enzyme found in CD4+ T cells, the human immune cells infected by HIV. The discovery could launch a more effective strategy for preventing the spread of HIV in the body with drugs targeting this enzyme, they say. A summary of their work was published online on April 21 in the journal Proceedings of the National Academy of...

Discovery raises hope for new methods to prevent the spread of HIV Researchers have discovered a new class of proteins capable of blocking the HIV virus from penetrating T-cells, raising hope that the proteins could be adapted for use in gels or sexual lubricants to provide a potent barrier against HIV infection. The proteins, called cnidarins, were found in a feathery coral collected in waters off Australia's northern coast. Researchers zeroed in on the proteins after screening...

Two Separate Studies On MERS-Coronavirus Offer Better Understanding Of Newly Emerging Disease
2014-04-29 09:33:16

Lawrence LeBlond for redOrbit.com - Your Universe Online Two separate studies this week are helping scientists gain a better understanding of the dangerous Middle East respiratory syndrome (MERS) coronavirus, a disease that has sickened more than 300 people and left at least a hundred dead since it was first reported in September 2012. HUMAN ANTIBODIES The first study comes from scientists at Dana-Farber Cancer Institute who have identified natural human antibodies against the virus...

The inventor of a germ killing cough cup is turning to the internet to raise funds to begin manufacturing his cups for kids so they can stay healthy and not miss school. SUGAR LAND, Texas, April 29, 2014 /PRNewswire/ -- It's called a Coughy Cup(TM). John Delatorre, founder of Coughy Cup, Inc. says the Coughy Cup(TM) is a new approach to managing the spread of germs and viruses from coughing. Change the lid and it can also be used for sneezing. Some cups also dispense tissue. "The Coughy...

In 2009 the influenza pH1N1 virus caused the first flu pandemic in the 21st century. The virus reached Finland in May 2009 and killed more than 50 people in the country. Since 2011 the pH1N1 virus infects Finns mainly during flu epidemics (winter/spring seasons). Infections with influenza pH1N1 virus vary from asymptomatic to serious complicated illnesses. World Health Organization has recommended Tamiflu for treatment of patients with severe or progressive illness. The disadvantage of...

LMU researchers have identified the structural features that enable the innate immune system to discriminate between viral and endogenous RNAs in living cells. When viruses infect cells, they take control of cellular metabolism and hijack cellular resources for the production of viral proteins. This process is dependent on viral RNA molecules that are delivered directly to (in the case of RNA viruses) and/or newly synthesized in the host cell, and provide the blueprints for the fabrication...

Cloaked DNA Nanodevices Survive Pilot Mission

[ Watch The Video: Virus-Inspired DNA Nanodevices ] Wyss Institute for Biologically Inspired Engineering at Harvard Successful foray opens door to virus-like DNA nanodevices that could diagnose diseased tissues and manufacture drugs to treat them It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invisible to the immune system. Now scientists at Harvard's Wyss Institute for...

Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna, together with colleagues of the ETH Zurich, have now shown how double stranded RNA, such as viral genetic information, is prevented from entering the nucleus of a cell. During the immune response against viral infection, the protein ADAR1 moves from the cell nucleus into the surrounding cytoplasm. There it modifies viral RNA to inhibit reproduction of the virus. But how is the human...

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...

Rubella virus is the cause of congenital rubella syndrome when infection occurs during the first weeks of pregnancy. Humans are the only known host of this virus. It is the only member of the genus of Rubivirus and belongs to the family of Togaviridae. Members of the Togaviridae family typically have a genome of single-stranded RNA of positive polarity which is enclosed by an icosahedral capsid. This genome has a length of about 9,757 nucleotides and encodes for two non-structural as well...

A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses have been described in detail although there are millions of different types. They are found in...

Vaccinia virus (VACV or VV) is a large, complex, enveloped virus belonging to the poxvirus family. It is well-known for its role in eradicating smallpox. It was the first human disease to to successfully be eradicated by science. The World Health Organization was the one who completed the endeavor. The vaccinia virus saw renewed interest in the early 21st century due to concerns about the smallpox virus being used as an agent for bioterrorism. They can be divided into four types:...

Simian immunodeficiency virus (SIV), also known as African Green Monkey virus, is a retrovirus able to infect at least 33 species of African primates. SIV has been present in monkeys and apes for at least 32,000 years, probably longer. Strains from two of these primate species have crossed the barriers into humans resulting in HIV-2 and HIV-1. Contraction involves contact with the blood of chimps that are often hunted for bushmeat in Africa. SIV infections appear in many cases to be...
