Creative Classroom: The ticks ‘come marching in’ in singing professor’s microbiology class

At the end of a recent “Medical Microbiology” class taught by Dr. Sheldon Campbell, students clapped, cheered heartily, and stomped their feet on the floor. A couple of them even shouted “Encore!”

It’s not quite the reaction one would expect from medical students who just spent 45 minutes lea... Read More

Chemists recruit anthrax to deliver cancer drugs

Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of MIT researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.

“Anthrax toxin ... Read More

New evidence of ancient multicellular life sets evolutionary timeline back 60 million years

A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago – nearly 60 million years before skeletal animals appeared during a huge growth spurt ...

Brazil releases 'good' mosquitoes to fight dengue fever

Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with bacteria that suppress dengue fever.

The hope is they will multiply, breed and become the majority of mosquitoes, thus reducing cases of the disease.

The initiative is part of a programme also takin... Read More

Bacterial 'communication system' could be used to stop, kill cancer cells, study finds

Cancer, while always dangerous, truly becomes life-threatening when cancer cells begin to spread to different areas throughout the body. Now, researchers at the University of Missouri have discovered that a molecule used as a communication system by bacteria can be manipulated to prevent cancer ... Read More

Three Irish Teens Win Google Science Fair Using Bacteria to Grow Food

A trio of Irish high-schoolers nabbed the top prize in this year's Google Science Fair with a project that speeds up crop growth by tapping into the naturally cozy relationship between soil microbes and plants.

After 11 months of experiments, the three 16-year-olds—Ciara Judge, Émer Hickey, a... Read More

Termites evolved complex bioreactors 30 million years ago

Achieving complete breakdown of plant biomass for energy conversion in industrialized bioreactors remains a complex challenge, but new research shows that termite fungus farmers solved this problem more than 30 million years ago. The new insight reveals that the great success of termite farmers ... Read More

Search for better biofuels microbes leads to the human gut

Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report.

Their study, repor... Read More

Sandia researchers find clues to superbug evolution

Imagine going to the hospital with one disease and coming home with something much worse, or not coming home at all.

With the emergence and spread of antibiotic-resistance pathogens, healthcare-associated infections have become a serious threat. On any given day about one in 25 hospital patie... Read More
