Tracking membranes of rupturing blood cells sheds light on malaria infection
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria... view more (2005-09-22)

Certain combination therapy found more effective for treating malaria in African children
Ugandan children who received the combination therapy of artemether-lumefantrine experienced a lower rate of treatment failure compared to other combination therapies, according to a study in the May 23/30 issue of JAMA, a theme issue on malaria.   view more (2007-05-23)

Inside rocks, implications for finding life on Mars
If a future space mission to Mars brings rocks back to Earth, Schopf said the techniques he has used, called confocal laser scanning microscopy and Raman spectroscopy, could enable scientists to look at microscopic fossils inside the rocks to search for signs of life, such as organic cell walls.   view more (2006-02-01)

Tarantulas produce silk from their feet
Researchers have found for the first time that tarantulas can produce silk from their feet as well as their spinnerets, a discovery with profound implications for why spiders began to spin silk in the first place.   view more (2006-09-28)

How a locust's eardrum could lead to tiny microphones
Being able to hear the smallest of noises is a matter of life or death for many insects, but for the scientists studying their hearing systems understanding how insect ears can be so sensitive could lead to new microphones able to capture and analyse extremely faint sounds.   view more (2006-03-31)

NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm.   view more (2006-12-08)

Biologists visualize protein interaction that may initiate viral infection
Biologists at Purdue University have taken a "snapshot" of a Velcro-like protein on a cell's surface just after it attached to the dengue virus, a linkup thought to initiate the early stages of infection.   view more (2006-02-10)

New light microscope sharpens scientists' focus
A new light microscope so powerful that it allows scientists peering inside cells to discern the precise location of nearly each individual protein they are studying has been developed and successfully demonstrated by scientists at the Howard Hughes Medical Institute's Janelia Farm Research Campus... view more (2006-08-11)

A tiny protein plays a big role in DNA repair
Two of DNA's worst enemies, ultraviolet light and chemical carcinogens, can wreak havoc on the molecule by mutating individual nucleotides or changing its physical structure.   view more (2006-05-09)

Quantum dot method rapidly identifies bacteria
A rapid method for detecting and identifying very small numbers of diverse bacteria, from anthrax to E. coli, has been developed by scientists from the National Cancer Institute (NCI) and National Institute of Standards and Technology (NIST).   view more (2006-03-31)

Uranium 'pearls' before slime
Since the discovery a little more than a decade ago of bacteria that chemically modify and neutralize toxic metals without apparent harm to themselves, scientists have wondered how on earth these microbes do it.   view more (2006-08-08)

Image of myosin-actin interaction revealed in cover story of Molecular Cell
Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model... view more (2005-09-30)

Run amok enzyme causes same problems in both humans and fruit flies
An enzyme found at elevated levels in several human cancers has been linked to abnormal tumor growth in fruit flies, a discovery that provides a new model for understanding the link between stem cell biology and cancer, according to researchers at the University of Oregon.   view more (2006-12-19)
