A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer.

Speedy analysis reveals mutations, insights into outbreak, along with clues to origin, spread.
Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, working with the Sierra Leone Ministry o... Read More
Aaron Wheeler is the director of an interdisciplinary research group at the University of Toronto in Canada. The group develop lab-on-a-chip techniques for applications in biology, chemistry and medicine.

Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease. In a new study in ACS’ Journal of Agricultural... Read More
Modern Earth is nothing like it was in its early days. Our planet was formed some 4.56 billion years ago when a giant stellar cloud collapsed on itself due its massive size and gravitational force. The explosion also generated the sun and many other planetary bodies, including those that would e... Read More
One of the food industry’s major recurring challenges, detecting highly carcinogenic toxins that occur naturally in our most common crops, could soon be solved by groundbreaking research that exploits aflatoxins’ fluorescent properties.
Aflatoxins are present in a wide... Read More
How handy would it be if, instead of taking your broken circuit board to the Genius Bar (again), you could just prompt it to heal itself? That’s the futuristic possibility researchers have recently inched ever so slightly toward, with the development of hybrid “living materials” made from bacter... Read More
Over the last few weeks, the numerous outbreaks of measles in Canada have led many public health officials and microbiologists to shake their collective heads. The reason is simple: this should not be happening. Of all the pathogenic viruses, this one has been on our radar for nearly 200 years a... Read More
The abilities of bacterial organisms to utilize the various strategies to resist antimicrobial compounds are all genetically encoded.
Intrinsic resistance is that type of resistance which is naturally coded and expressed by all (or almost all) strains of that particular bacterial species. An... Read More
A pesar de los beneficios que suponen las vacunas, muchas personas desconocen cómo funcionan e incluso desconfían de su acción. Las vacunas siempre son más seguras que la propia enfermedad de la que protegen. Algunas enfermedades infecciosas no tienen un tratamiento efectivo y las vacunas son la... Read More
Scientists working to understand the devastating bat disease known as white-nose syndrome (WNS) now have a new, non-lethal tool to identify bats with WNS lesions —ultraviolet, or UV, light.
If long-wave UV light is directed at the wings of bats with white-nose syndrome, it produces a distinct... Read More
In 2012 I wrote a story for Nature about a strange illness called Kawasaki Disease whose cause has eluded scientists for over 50 years. The diseases causes inflammation of the blood vessels in small children that leads to fever, rashes and reddening, and even coronary aneurysms that can cause he... Read More
When most people look at soil, they just see dirt. When I look at soil, I see billions of microorganisms crawling atop one another, consuming the dead in a feasting frenzy that stops for nothing save a deep freeze. I see microbes and their enzymes, the digestive juices that break down, transform... Read More
Growth of Acetobacter pasteurianus on glucose, yeast extract, calcium carbonate, ethanol medium.
Formation of acetic acid from ethanol oxidation is shown by a clear halo around bacterial growth due to dissolution of calcium carbonate.
Organism: Acetobacter pasteurianus. Incubation conditions:... Read More
The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell. The scientists of the International School for Advanced Stu... Read More
Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.
It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study p... Read More
The yeast S.pombe is one of the best-studied microbes in the world. First isolated from East African millet beer over a century ago, it's been used as a model organism in molecular and cell biology for the past sixty years. And yet scientists have now just uncovered what may be its most striking... Read More
Researchers at the University of Virginia School of Medicine studying a potentially deadly parasitic infection have discovered a previously unknown way that human cells are killed, with the parasitic amoeba essentially nibbling cells to death – as a piranha might attack its prey.
Until now, r... Read More
In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections t... Read More
