New estimates indicate that over 650,000 children develop tuberculosis (TB) every year in the 22 countries with a high burden of the disease -- almost 25 percent higher than the total number of new cases worldwide estimated by WHO in 2012. The research also suggests that about 15 million childre... Read More
“She did pioneering work in genetics, but it was her husband who won a Nobel price.” So said an obituary in the British newspaper The Guardian regarding Esther Lederberg, a North American microbiologist married to Joshua Lederberg from 1946 to 1966 . Being married to and working along such a... Read More
We know that life on earth is incredibly diverse. It can survive deep in the trenches of the ocean and in the frozen permafrost of the arctic. Surely we have much to learn from the study of life, but we also have much to learn about the virus. Even though they are not considered living things, t... Read More
Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug an... Read More
Risks and benefits of unproven treatments, as World Health Organization approves use in crisis.
Two Liberian doctors are set to become the first Africans to receive an experimental drug against the Ebola virus. The news comes as the World Health Organization concludes that it is ethical to us... Read More
A simple, inexpensive dip-and-dry treatment can convert ordinary silk into a fabric that kills disease-causing bacteria -- even the armor-coated spores of microbes like anthrax -- in minutes, scientists are reporting in the journal ACS Applied Materials & Interfaces. They describe a range of pot... Read More
Science and news cycles sometimes converge in unhandy ways. That was the case on on January 1, when word came out of Shenzen, a Chinese city bordering Hong Kong, that a 39-year-old bus driver, surnamed Chen, had died of the H5N1 (or bird flu) virus. The deeply personal tragedy for Chen and his f... Read More
Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team of researchers has described how in Paramecia, mating types are transmitted from generation to ge... Read More
Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.
Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More
Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.
The change, which expands the remit of an earlier data-sharing policy, is ... Read More
Nearly two years after the Deepwater Horizon disaster gushed millions of barrels of oil into the Gulf of Mexico, tar balls from the spill still turn up on Alabama's shores after storms. Now, one researcher is recommending that people steer clear of these tar balls after studies find them chock-f... Read More
Could Ebola go airborne? That’s the fear set off last week by a New York Times op-ed entitled “What We’re Afraid to Say about Ebola” from Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. Although clinicians readily agree that th... Read More
Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.
MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More
I have been following TWIP for several years. I am a software engineer and parasitology is only an avocation. As an undergraduate in the early 80's I discovered my love of history of science and ecology, although I continued the p... Read More
Antibiotic resistance poses a dire threat in hospitals and communities. To help limit such risk, health care professionals should begin sequencing the DNA of offending bacteria, the White House’s council of science advisors said in a new report. Armed with genome-sequencing technology that enabl... Read More
What do the Curiosity rover and a bone allograft have in common? They both have got to be super duper clean.
That’s why AlloSource, a Colorado-based nonprofit that specializes in human tissue donation, has signed a Space Act Agreement with NASA and its Jet Propulsion Laboratory (JPL), to make... Read More
Careful what you sniff. Especially if you work at an industrial hog farm. Because a small study finds that drug-resistant bacteria may hang out in the noses of some workers even after four days away from work following exposure. Almost half of the tested workers continued to harbor drug-resistan... Read More
The same viruses that make us sick can take up residence in and on the human body without provoking a sneeze, cough or other troublesome symptom, according to new research. On average, healthy individuals carry about five types of viruses on their bodies, the researchers report. The study is the... Read More
A mathematical model that replicates Ebola outbreaks can no longer be used to ascertain the eventual scale of the current epidemic, finds research conducted by the University of Warwick.
Dr Thomas House, of the University’s Warwick Mathematics Institute, developed a model that incorporated da... Read More
Lessons learned from Florence Nightingale could prevent the spread of harmful bugs by allowing "friendly" bacteria into hospitals, an expert has claimed.
Sterile conditions in wards and operating theatres may be doing more harm than good by wiping out organisms that keep dangerous microbes at b... Read More
