A Minnesota man who returned from a trip to West Africa has been diagnosed with Lassa fever, a severe and sometimes deadly viral disease rarely seen in the United States, health officials said.
The man, who was hospitalized with fever and confusion on March 31, was confirmed to have Lassa fev... Read More
By now, many of us are aware that a considerable portion (45% or more) of the human genome consists of transposable elements. These are mobile genetic sequences, such as Alu repeats and long and short interspersed nuclear elements (LINEs and SINEs). A whopping 18% of this so-called "dark matter ... Read More
Some may think of turkeys as good for just lunch meat and holiday meals, but bioengineers at UC Berkeley saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathog... Read More
The Lechuguilla Cave in New Mexico is a network of chambers stretching 1,600 feet underground. The bacteria that grow on the walls of its most remote recesses have been living in complete isolation for more than four million years.
In 2010, Gerry Wright, a microbiologist at McMaster Universit... Read More
Researchers at Duke University say they have created a blood test that can determine whether a person's respiratory illness is caused by a bacterial infection or a virus, with over 90 percent accuracy.
What's more, the test only takes about 12 hours to get results. Current methods take severa... Read More
Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says University of Oregon geologist Gregory Retallack, based on images and data captured by the rover Curiosity.
NASA rovers have shown Martian landscapes littered with loos... Read More

The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person’s ethnicity, new research shows.
Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging t... Read More
Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nan... Read More
A new test for HPV has been cleared as way to screen for cervical cancer, but doctors are concerned that it doesn't do enough to protect younger women.
By its name alone, the Pap smear sounds like an uncomfortable procedure. Say it aloud: Pap smear. And it’s not too pretty to experience eithe... Read More
Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.

A team of scientists from Washington State University has discovered how one of the planet’s most deadly known viruses employs burglary-ring-like teamwork to infiltrate the human cell.
Nipah virus is so menacing that the nation’s top infectious disease experts served as consultants in the fil... Read More
In a new study, Harvard scientists show that the bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located deep in soil and sediment while remaining at the surface.

A new biological treatment could help dairy cattle stave off uterine diseases and eventually may help improve food safety for humans, a University of Florida study shows.
Kwang Cheol Jeong, an assistant professor in animal sciences and UF’s Emerging Pathogens Institute, examined cattle uterin... Read More
As the deadly outbreak of Ebola in West Africa continues to claim lives, Wellcome Trust director Dr Jeremy Farrar calls for Africans to be given access to experimental Ebola medication. This joint statement with Prof David Heymann, head of the Chatham House Centre on Global Health Security, and ... Read More
Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn al... Read More
The hemagglutinin (HA) and neuraminidase (NA) glycoproteins of the influenza virus particle serve distinct functions during infection. The HA binds sialic acid-containing cellular receptors and mediates fusion of the viral and cell membranes, while the NA removes sialic acids from glycoproteins.... Read More
Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More
By evaluating the bacteria and fungi found in fossilized feces, microbiologists are providing evidence to help support archeologists' hypotheses regarding cultures living in the Caribbean over 1,500 years ago. Researchers discuss how the analysis of 1,500-year-old coprolites from archeologica... Read More
