News: This Modified Common Cold Virus Specifically Targets & Kills Cancer (& Leaves Healthy Cells Alone)
The search for a cancer treatment that selectively finds and kills only the cancerous cells has just made a giant leap forward.
News: Scientists Discover How to Track Down HIV's Hiding Spots—A Potential Pathway to a Cure
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
News: How Gut Bacteria Can Make Chemo More Effective
We can add one more health effect of our gut bacteria to the growing list. Researchers from the UK have just reported that the gut microbiota plays a role, both directly and indirectly, on the toxicity and efficacy of chemotherapy. Their findings are published online in the journal Nature Reviews Gastroenterology & Hepatology.
News: A New Compound Kills the Growth-Stunting Whipworm Parasite That Infects Half a Billion People
Somewhere around 600–800 million people in the world are infected with whipworm (Trichuris trichiura), an infection they got from ingesting soil or water contaminated with feces of infected animals or people containing the parasite's eggs.
News: Scientists Are Flabbergasted to Discover Asthma Drugs May Stop Viral Pneumonia
By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there.
News: HIV Co-Opts the Body's First Line of Defense—Using It as a Shuttle to Take Over
A new study just out reveals that HIV takes hold in the human body with the help of cells that usually work to heal, not kill.
News: We've Finally Developed a Test for Mysterious Prion Diseases— Parkinson's & Alzheimer's Could Be Next
Prion diseases are a group of infectious brain diseases that causes extensive tissue damage, resulting in sponge-like spaces in brain tissue. Prions include Creutzfeldt-Jakob disease in humans, bovine spongiform encephalopathy (often called mad cow disease), and chronic wasting disease in hoofed ruminant mammals.
News: New Finding Shows How Deadly, Flesh-Eating Strep Toxins Help the Bacteria Burrow Deeper into Tissues
Where in the world did it come from? All of a sudden, one day, someone had an infection with flesh-eating bacteria. It captured headlines and worldwide attention because it was such a severe, strange, uncontrollable, and really disgusting condition.
News: Early Treatment with Vaccine Could Slow Precancerous HPV
Usually, we think of vaccines as preventative, a shot we get to prevent the flu or some childhood disease like measles or mumps. But there are vaccines for other purposes, such as the ones studied by researchers from the Netherlands.
News: This Asymptomatic Virus Can Damage the Immune System & May Trigger Celiac
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
News: Unexplained Link to Hepatitis Infections Could Inform Parkinson's Mysterious Causes
Two viral liver diseases could help us find the path toward the cause of Parkinson's disease. Researchers from the University of Oxford and UCL Institute of Neurology in London have reported an association between hepatitis B and C infections and an increased risk of Parkinson's disease. Their findings were published early online in the journal Neurology.
News: Bloodsucking Flies Act as 'Flying Syringes' to Detect Malaria & Other Emerging Diseases in Wild Animals
Researchers have been studying the blood meals of flies to understand the flow of infectious pathogens in wild animals.
News: Researchers Discover Key Proteins Malaria Uses to Infect the Liver—A Key Step in Stopping the Parasite
When the mosquito that carries the malaria parasite (Plasmodium falciparum) bites someone, the parasite must travel to the liver where it undergoes part of its lifecycle before infecting red blood cells and spreading to its next host. Until now, the first step of how the parasite gets to the liver hasn't been clear.
News: New Study Says Stopping Slimy Biofilms Could Save Thousands a Year from Legionnaires' Disease
In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention. Several days later, many of the attendees experienced symptoms of severe pneumonia. By the beginning of August, 22 people had died. The Centers for Disease Control and Prevention (CDC) estimate that about 180 people were sickened and 29 people died before this mysterious outbreak burnt out.
News: We've Found the Back Door HIV Uses to Hide in the Brain—& It Could Help Us Take the Virus Down
Over 1.2 million people in the US are infected with human immunodeficiency virus (HIV)—and one out of eight of them don't know it. Even after decades of intense research into the virus, there's still no cure for it. One of the big problems is that the virus hides out in certain cells of the body, resisting treatments that kill it.
News: The Root Cause of Type 1 Diabetes Could Be a Common Childhood Viral Infection
A young child becomes very thirsty very often and seems tired all the time. A visit to the pediatrician determines she has type 1 diabetes. The onset of type 1 diabetes may seem sudden, and it can be, but the disease may actually have been triggered by common childhood viruses years earlier.
News: Shapeshifting Cholera Bacteria Corkscrew Themselves to Twist into the Gut
Cholera may be rare in the US, but cases of the disease have increased worldwide since 2005, particularly in Africa, southeast Asia, and Haiti. An estimated 3 to 5 million people are infected, and more than 100,000 die from the disease globally each year, mostly from dehydration.
News: Genetically-Modified Parasites Could Save People from Malaria
You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body.
News: First Full Genome Analysis Solves the Mystery of How Zika Got So Dangerous
The mention of Zika can strike fear in the hearts of pregnant women. With infections increasing around the world, including in the US, researchers are fighting the clock to figure out how the virus can have such horrific effects in some people.
News: The Unusual Stomach-Survival Mechanisms of Ulcer-Causing Bacteria Could Be Its Achilles Heel
The story of Helicobacter pylori is a real testament to the tenacity of medical researchers to prove their hypothesis. It took decades before the scientific world would accept that the bacteria H. pylori caused ulcers.
