An Ebola virus protein can cause massive inflammation and leaky blood vessels

Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.

A virus that melts sea stars

Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More

Powdery Mildew

Sawadaea sp. (Erysiphaceae, Erysiphales) is a powdery mildew that infects Acer sp. (Maple). Infected maple leaves, usually on the adaxial surface, are covered with dense mycelia (of white to grey powder colour) with scattered chasmothecia (fruiting body, brown to dark-brown ball-like structure)....

Ancient Viruses Lurk In Frozen Caribou Poo

A careful examination of frozen caribou poop has turned up two never-before-seen viruses.

The viruses are hundreds of years old: One of them probably infected plants the caribous ate. The other may have infected insects that buzzed around the animals.

The findings prove viruses can survive... Read More

SA vaccine cuts bacteria to size

South Africa has shown the world that a vaccine against the strains of bacteria that can cause deadly meningitis and pneumonia in children works.

A study published today in the New England Journal of Medicine, to coincide with world Pneumonia Day, records the country's success in reducing pne... Read More

Vaccine-resistant polio strain discovered

The global initiative to eradicate poliomyelitis through routine vaccination has helped reduce the number of cases by more than 99% in 30 years. However, major epidemics are still occurring today. Researchers have identified the virus responsible for deadly and recent outbreaks, and have sequenc... Read More

Including antibiotics in the list of the immaterial heritage of the UNESCO

Antibiotic resistance is increasing worldwide, and represents a dramatic threat for public health. Antibiotics are a common and universal good, a treasure that we must urgently protect. It is a duty for each citizen of the world. We intend to ask the UNESCO to include the antibiotics in the list... Read More

Biochemistry detective work: algae at night

Photosynthesis is probably the most well-known aspect of plant biochemistry. It enables plants, algae, and select bacteria to transform the energy from sunlight during the daytime into chemical energy in the form of sugars and starches (as well as oils and proteins), and it involves taking in ca...

Viral Switches Share a Shape

A hinge in the RNA genome of the virus that causes hepatitis C works like a switch that can be flipped to prevent it from replicating in infected cells. Scientists have discovered that this shape is shared by several other viruses—among them one that kills cancer cells.

That’s Seneca Valley v... Read More

New study reveals why some people may be immune to HIV-1

Natural genetic variation in a protective antiviral enzyme holds promise for new therapies.

Doctors have long been mystified as to why HIV-1 rapidly sickens some individuals, while in others the virus has difficulties gaining a foothold. Now, a study of genetic variation in HIV-1 and in the c... Read More

Study Shows Bed Bugs Can Transmit Parasite that Causes Chagas Disease

The bed bug may be just as dangerous as its sinister cousin, the triatomine, or “kissing” bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that ...
