There's nothing quite like the pastime of cloud watching. We can spend hours watching these ethereal formations pass by. We can find shapes in them, try to imagine where they came from -- and where they are going -- and whether or not they are going to open up and douse us with precipitation.

UT Southwestern Medical Center scientists have synthesized a peptide that shows potential for pharmaceutical development into agents for treating infections, neurodegenerative disorders, and cancer through an ability to induce a cell-recycling process called autophagy.
Autophagy is a fundamen... Read More
Epigenetic controls like histone modification and chromatin remodeling play important regulatory roles in all cellular processes requiring access to the genome. So when a herpes simplex virus or varicella-zoster virus infects a human cell, one of the first things it does is attack the cell’s epi... Read More
A team of scientists just won a battle in the war against antibiotic-resistant "superbugs" -- and only time will tell if their feat is akin to the bacterial "Battle of Gettysburg" that turns the tide toward victory.
They won this particular battle, or at least gained some critical intelligenc... Read More
As the Northern Hemisphere shivers through winter, bacteria in Antarctica are employing an inventive strategy to survive the extreme cold: they use a specialized antifreeze protein to latch onto the ice and stay afloat.
Antifreeze proteins generally protect their hosts from freezing by contro... Read More
Biochemical trick could aid in recovery of the metal from waste. Gold prospectors may one day use Petri dishes to help with their quests. A species of bacterium forms nanoscale gold nuggets to help it to grow in toxic solutions of the precious metal, reports a paper published online today in Nat... Read More
Prions can turn their victims into zombies—they punch holes in their brains and steal their souls. The infected stumble about, might take a bite out of someone if hungry, certainly don’t think straight and, most important, lose their memories and with them the very essence of their humanity or “...

Plant and animal cells have two genomes—in the nucleus and the mitochondria. A new study describes how a clash between the two makes fruit flies sick. Diseases from a mutation in one genome are complicated enough, but some illnesses arise from errant interactions between the DNA in the nucleus a... Read More

A New York company plans to build a bacteria-based power generation facility at Brunswick Landing.
Village Green Ventures hopes to file permit applications for the project by the end of the month and will hold a public meeting about it Wednesday evening.
Planned for 2 acres of property on ... Read More
Imagine if you could take living cells, load them into a printer, and squirt out a 3D tissue that could develop into a kidney or a heart. Scientists are one step closer to that reality, now that they have developed the first printer for embryonic human stem cells.
In a new study, researchers ... Read More
Marine bioluminescent Photobacterium kishitanii
The genus Photobacterium was first coined by Martin Beijerinck, in 1889, and originally referred to all bacteria capable of light production. Species belonging to Photobacterium are gram negative, rod shaped, chemoorganotrophic, facultative aerob... Read More
No bacterium lives alone – it is constantly encountering members of its own species as well as other kinds of bacteria and diverse organisms like viruses, fungi, plants and animals. To navigate a complex world, microbes use chemical signals to sense and communicate with one another... Read More
Bacteria are ubiquitous and some of them are real survival specialists – a property, which is particularly challenging for space missions. The spacecraft that are sent on their long journey into space should be as clean as possible and considerably reduced in microbial burden, since the risk of ... Read More
Swiss researchers have discovered that flow cytometry can now quantify microbial cells in drinking water—and do so in minutes rather than days. Stemming from work at aquatic research institute Eawag (Dübendorf, Switzerland) and extensive tests both in Switzerland and abroad, the optical techinqu... Read More

A genetically reprogrammed Herpes simplex virus (HSV) can cure metastatic diffusion of human cancer cells in the abdomen of laboratory mice, according to a new study published January 31 in the Open Access journal PLOS Pathogens. The paper reports on the collaborative research from scientists at... Read More
The microbiome of breast milk is influenced by many factors, including maternal weight and how the baby was delivered, according to research published in the American Journal of Clinical Nutrition.
