The first case of Ebola in the United States was announced today, with a patient in Dallas who traveled to the US from Liberia. The resultant hysteria and xenophobia prompts this reminder. There is NO need to panic.
Ebola is NOT transmitted before a patient develops symptoms. Ebola is transmi... Read More
Is complex life rare in the cosmos? The idea that it could be rests on the observation that the existence of life like us – with large, energy hungry, complicated cells – may be contingent on a number of very specific and unlikely factors in the history of the Earth. Added together they suggest ... Read More
Plants have a symbiotic relationship with certain bacteria. These 'commensal' bacteria help the plants extract nutrients and defend against invaders -- an important step in preventing pathogens from contaminating fruits and vegetables. Now, scientists have discovered that plants may package thei... Read More
Researchers have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.

The DNA of a virus once thought confined to the cells of algae may in fact invade the biological kingdom of mice and men, according to a new study from researchers at Johns Hopkins University in Baltimore and the University of Nebraska-Lincoln.
The researchers, whose paper appeared Oct. 27 in... Read More
These days, antibiotics are no silver bullet. In fact, if you get them in the hospital, you may end up with an additional infection. Like the bug Clostridium difficile, or C. diff — which infects more than 300,000 Americans a year and kills some 14,000. C. diff flourishes in the post-antibiotic,... Read More
Federal officials today announced the first case of Ebola diagnosed in the U.S. The male patient was admitted to Texas Health Presbyterian Hospital Dallas and placed in strict isolation on September 28 after flying from Liberia to visit family in north Texas. The patient left Liberia on Septembe... Read More
Humans are not the only primates ravaged by the deadly Ebola virus. Chimps and gorillas are also susceptible to the disease. The current Ebola epidemic, the biggest in human history, may have started with the butchering of an infected fruit bat. But it just as easily could have come from a chimp... Read More
My research is focused on the biofilms formation, Motility (swarming and swiming ) and QS in fluorescent Pseudomonas (P. aeruginosa and P. fluorescens).
In laboratory a interaction had been with insect and bacteria metabo... Read More
Recent breakthroughs may pave the way for vaccines and new drugs for those infected by parasitic helminths. These flatworms, including tapeworms that cause hydatid diseases and neurocysticercosis, liver flukes, and blood flukes (schistosomes), infect more than 300 million people and cause approx...

The natural photo degradation of diazepam (valium) and similar medicines – followed by bacterial breakdown – may reduce their potentially harmful impact on the UK’s freshwater environment, a team of researchers has said.
Diazepam – used to treat anxiety and other similar conditions – has been... Read More
Two new studies shed light on how cells sense and respond to chemical trails. Amoebas aren’t the only cells that crawl: Movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies from Johns Hopkins, researchers answer lo... Read More
For decades, honeybees have been battling a deadly disease that kills off their babies (larvae) and leads to hive collapse. It’s called American Foulbrood and its effects are so devastating and infectious, it often requires infected hives to be burned to the ground.
Treating Foulbrood is comp... Read More
As the world experiences a wakeup call about the rise of drug-resistant infections, a new approach to creating smarter, “programmable” drugs could combat the two major problems with life-saving drugs today.
On the one hand, today’s antibiotics work a little too well. They not only kill infect... Read More
This article was first published in 2013 on the website for the Society of Integrative and Comparative Biology.
Many plants do not want to be eaten. They avoid this fate by producing deadly toxins and carcinogenic poisons, such as those associated with the aptly named poison ivy, poison sumac... Read More
In an ideal world, health care workers returning from West Africa would get a quick blood test to prove they aren't carrying the Ebola virus. A test like that would likely put to rest some of the anxiety surrounding these doctors, nurses and scientists.
Unfortunately, even the best blood test... Read More
On July 20 a man who was ill flew on commercial planes from the heart of the Ebola epidemic in Liberia to Lagos, Nigeria's largest city. That man became Nigeria's first Ebola case—the index patient. In a matter of weeks some 19 people across two states were diagnosed with the disease (with one a... Read More

Over the past eight years, step-by-step, researchers have established a basic understanding of the CRISPR defenses against foreign DNA so widely used by both bacteria and archaea. We related the early story on STC in 2008 and commented on six additional questions in 2011. Still, questions remain... Read More
Nurse Amber Vinson's discharge from the hospital Tuesday brings to seven the number of American patients who have survived Ebola, leading many people to wonder what has allowed them to beat the odds.
In West Africa, about 70% of patients die from the Ebola virus, according to the World Health... Read More
