Strengthened microtubules aid cell migration
Migrating cells use stiffened microtubules to push through tissue barriers, seeking out weak points in tissue, according to a Northwestern Medicine study published in Cell Reports......»»
Researchers unveil PI3K enzyme"s dual accelerator and brake mechanisms
A group of researchers have expanded conventional knowledge on a critical enzyme that controls cell migration. In a publication in the journal Nature Communications, they reported that phosphoinositide 3-kinase (PI3K) not only acts as an accelerator.....»»
Unveiling the mysteries of cell division in embryos with timelapse photography
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain elusive in the first cells of.....»»
Airborne observations of Asian monsoon sees ozone-depleting substances lofting into the stratosphere
Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, new research shows......»»
Scientists study lipids cell by cell, making new cancer research possible
Imagine being able to look inside a single cancer cell and see how it communicates with its neighbors. Scientists are celebrating a new technique that lets them study the fatty contents of cancer cells, one by one......»»

Researchers map protein network dynamics during cell division
An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the.....»»
GM sees opportunity for hydrogen as diesel alternative
GM is participating in a five-year federally funded project that will deploy its hydrogen fuel cell technology in a vehicle for use by a utility company......»»
The effects of climate variability on children"s migration and childcare practices in sub-Saharan Africa
Shifting weather caused by climate change, especially drought and heat, is linked to a rise in the number of children being raised outside of their biological parents' households in sub-Saharan Africa, according to a study led by researchers at Penn.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Team finds direct evidence of "itinerant breeding" in East Coast shorebird species
Migration and reproduction are two of the most demanding events in a bird's annual cycle, so much so that the vast majority of migratory birds separate the two tasks into different times of the year......»»
New model finds previous cell division calculations ignore drivers at the molecular scale
When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass......»»
First evidence of human occupation in lava tube cave in Saudi Arabia
Recent strides in interdisciplinary archaeological research in Arabia have unveiled new insights into the evolution and historical development of regional human populations, as well as the dynamic patterns of cultural change, migration, and adaptatio.....»»
Birds of a feather flocking together: Research shows storks prefer to fly with conspecifics during migration
With long legs and large wings, the white stork is a prominent star of the pageant that is animal migration. Flying from Europe towards Africa in autumn, and then back again in spring, birds can be seen taking to the sky in conspicuous flocks that he.....»»
Cut light pollution and treat glass to help migrating birds, say researchers
Spring bird migration has begun. Under cover of darkness, 2.5–3.5 billion birds will fly northward to their breeding grounds in the United States and Canada. According to the Cornell Lab of Ornithology, now is one of the most important times of yea.....»»
Nanovials method for immune cell screening uncovers receptors that target prostate cancer
A recent UCLA study demonstrates a new process for screening T cells, part of the body's natural defenses, for characteristics vital to the success of cell-based treatments. The method filters T cells based on the receptor proteins found on their sur.....»»
Scientists share single-cell atlas for the highly regenerative worm, Pristina leidyi
An international team of scientists, including B. Duygu Özpolat at Washington University in St. Louis, has published the first single-cell atlas for Pristina leidyi (Pristina), the water nymph worm, a segmented annelid with extraordinary regenerativ.....»»
A rechargeable nanotorch: Afterglow luminescence imaging tracks cell-based microrobots in real time
An afterglow luminescent nanoprobe opens up new possibilities for imaging living cells. As a research team reports in the journal Angewandte Chemie International Edition, their new "nanotorch" can continue to luminesce for more than 10 days after a s.....»»
Researchers map 33 new big game migrations across American West
A new set of maps that document the movements of ungulates was published today in the fourth volume of the Ungulate Migrations of the Western United States. The maps in this collaborative U.S. Geological Survey report series reveal the migration rout.....»»
Biologists reveal how gyrase resolves DNA entanglements
Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in every cell in the body have one thing in common; th.....»»
Scientists reconstruct assembly of the human centriole, image by image, for the first time
Cells contain various specialized structures—such as the nucleus, mitochondria or peroxisomes—known as "organelles." Tracing their genesis and determining their structure is fundamental to understanding cell function and the pathologies linked to.....»»
