Brewing yeasts reveal secrets of chromosomal warfare and dysfunction

Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its clo... Read More

Rare byproduct of marine bacteria kills cancer cells by snipping their DNA

Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.

The molecule, lomaiviticin A, was previously shown to be lethal to cultured human cancer cells, but the mech... Read More

A Snippet: One Fungus, Two Bacteria

How often have you heard of two or more bacterial species coexisting within the same cell of a host? It’s known to happen with some frequency in some amebas, insects and other invertebrates (including the strange case of the mealybug bacteria, which have an endosymbiotic bacterium that carries a...

Natural History is Dying, and We Are All the Losers

A few weeks ago, I came across a new paper in BioScience called “Natural History’s Place in Science and Society” that contained the following graph.

On the right axis and indicated by the line surrounded by dots is the proportion of introductory biology texts devoted to natural history since ... Read More

Molecular Computer Detects Ebola and Marburg Viruses

Material from deadly pathogens triggers alerts directly, and could speed detection. Early detection is key to slowing outbreaks of Ebola, such as the one currently spreading across west Africa that is estimated to have infected almost 1000 people, according to the latest World Health Organizatio...

Drugs fail to reawaken dormant HIV infection

Scientists report that compounds they hoped would "wake up" dormant reservoirs of HIV inside immune system T cells -- a strategy designed to reverse latency and make the cells vulnerable to destruction -- have failed to do so in laboratory tests of such white blood cells taken directly from pati...

ASM GM 2014 - The Effect of Pancreatic Cancer on the Oral Microbiome

In the United States, approximately 40,000 people die every year due to pancreatic adenocarcinoma, making it the fourth leading cause of cancer related death. Patients diagno... Read More

Bacteria: A day in the life

MIT study finds ocean bacteria follow predictable patterns of daily activity.

We are all creatures of habit, and a new MIT study finds ocean bacteria are no exception.

In a paper published this week in Science, researchers from MIT and elsewhere report that microbes in the open ocean follo... Read More

US Travelers Return Home With Tropical Disease. Will It Spread In The States?

If you happened to be reading state health departments’ outbreak announcements this past weekend, you might have seen something interesting.

(You don’t do this? Hmm.)

Three states — Rhode Island, North Carolina and Tennessee — all said that they have identified residents who have been diag... Read More

TWiP 75 letters


David writes (re lice and iron):


All I remember that I know is that one time I let my cat endure a heavy flea infestation for an unconscionably long time. I redeemed myself, if at all, by the knowledge that I slept with her a lot, and so endured a share myself (b... Read More

ULTRASMALL BACTERIA FROM ANTARCTIC LAKE RAISE QUESTIONS ABOUT THE LIMITS OF LIFE

Imagine you were forced to live in perpetually subzero temperatures, with no oxygen, no light, and way more salt than your system could handle. How would you manage? One way might be to get extremely small. At least, that seems to be what’s happening in a frozen Antarctic lake that’s cut off fro... Read More

Why a bacterium got its curve — and why biologists should know

Drawing from his engineering background, Princeton University researcher Alexandre Persat had a notion as to why the bacteria Caulobacter crescentus are curved — a hunch that now could lead to a new way of studying the evolution of bacteria, according to research published in the journal Nature ...

UEA researchers discover Achilles’ heel in antibiotic-resistant bacteria

Scientists at the University of East Anglia have made a breakthrough in the race to solve antibiotic resistance.

New research published today in the journal Nature reveals an Achilles’ heel in the defensive barrier which surrounds drug-resistant bacterial cells.

The findings pave the way f... Read More

Deadly Human Pathogen Cryptococcus Fully Sequenced

DURHAM, NC - Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and... Read More

Urease: an anti-microbial target in bacteria and fungi

Urea is a small molecule formed as proteins are broken down. It’s excreted in urine, but isn’t particularly toxic at low levels so it’s found in cells throughout the body. The molecular structure of urea is below, and as it contains nitrogen (N) several pathogens have adapted to use it as a nitr... Read More

Bird flu 'danger zones' mapped

The "danger zones" in Asia which are vulnerable to a deadly bird flu have been mapped by scientists.

The virus, called H7N9, has infected 433 people mostly in China and has killed 62.

The study, published in Nature Communications, showed parts of Bangladesh, India and Vietnam could easily ... Read More

Smallpox Virus Found In Unsecured NIH Lab

Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: vials labeled "variola" — in other words, smallpox.

Under international convention, there are supposed to be only two stashes of this deadly vir... Read More

Report on Viruses Looks Beyond Disease

Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... Read More
