New Microscopy Technique Offers Close-Up, Real-Time View of Cellular Phenomena

100314150920-large

This image, taken with atomic force microscopy, shows E. coli bacteria after they have been exposed to the antimicrobial peptide CM15. The peptides have begun destroying the bacteria’s cell walls.

For two decades, scientists have been pursuing a potential new way to treat bacterial infections, using naturally occurring proteins known as antimicrobial peptides (AMPs). Now, MIT scientists have recorded the first microscopic images showing the deadly effects of AMPs, most of which kill by poking holes in bacterial cell membranes.

Canine Morphology: Hunting for Genes and Tracking Mutations

100301201937-large

Researchers studying the dog genome have a new understanding of why domestic dogs vary so much in size, shape, coat texture, color and patterning.

Why do domestic dogs vary so much in size, shape, coat texture, color and patterning? Study of the dog genome has reached a point where the molecular mechanisms governing such variation across mammalian species are becoming understood.

Picasso’s Le Rêve painting, as seen through the eyes of a person with age-related macular degeneration.

An international research team led by Columbia University Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide.

Is an Animal’s Agility Affected by the Position of Its Eyes?

100222200856-large

Researchers sampled the relationship between agility and vision between frontal eyed species, such as cats, to lateral-eyed mammals, such as rabbits, to establish if the positioning of the eyes resulted in limitations to speed and agility.

New research from scientists in Liverpool has revealed the relationship between agility and vision in mammals. The study, published in the Journal of Anatomy, sampled 51 species to compare the relationship between agility and vision between frontal eyed species, such as cats, to lateral-eyed mammals, such as rabbits, to establish if the positioning of the eyes resulted in limitations to speed and agility.

Life’s Smallest Motor, Cargo Carrier of the Cells, Moves Like a Seesaw

100218091238-large

A molecular motor gives up its secrets.

Life’s smallest motor — a protein that shuttles cargo within cells and helps cells divide — does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and Brandeis University.

Built-in Amps: How Subtle Head Motions, Quiet Sounds Are Reported to the Brain

100209091842-large

A single hair cell from a frog ear magnified by a scanning electron microscope.

The phrase “perk up your ears” made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain.

Agricultural Scientists Sequence Genome of Grass That Can Be a Biofuel Model Crop

100210131957

John Vogel of the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) with the first wild grass to be sequenced, Brachypodium distachyon.

U.S. Department of Agriculture (USDA) scientists and their colleagues at the Department of Energy (DOE) Joint Genome Institute have announced that they have completed sequencing the genome of a kind of wild grass that will enable researchers to shed light on the genetics behind hardier varieties of wheat and improved varieties of biofuel crops.
