University of the Pacific researchers give peptides a longer life
Researchers at University of the Pacific have developed a biochemical trick that can significantly extend the lifespan of peptides, smaller cousins of proteins. The finding opens up new possibilities for creating peptides to treat cancer, infertility and other conditions. The research, led by Mamoun Alhamadsheh, assistant professor of pharmacy at Pacific, is featured in the November issue of Nature Reviews Drug Discovery, a publication that spotlights high-impact papers from Nature, Cell and other scientific journals.

New findings rock long-held assumptions about ancient mass extinction
In research to be presented Nov. 4 at the annual meeting of the Geological Society of America and published in the October issue of the journal Geology, a University of Texas at Dallas geologist and his colleagues describe new findings that challenge the currently accepted model of the 'Great Dying,' a catastrophic extinction event that occurred more than 250 million years ago.

Predicting cancer's growth from few clues
Duke mathematicians are developing ways to help doctors predict how different cancers are likely to progress when measurements of tumor growth are hard to come by. In a new study, they describe a way to compare common models of tumor growth, using only two time-point measurements of tumor size -- often the maximum available before patients begin treatment. Determining which models work best for different cancers is key to designing optimum treatment strategies.

Planting in clumps boosts wetland restoration success
A Duke-led study finds that when restoring coastal wetlands, clumping newly planted marsh grasses next to each other, with little or no space in between, can spur positive interactions between plants and boost growth and survival by up to 300 percent in one growing season, at no additional cost. The new planting design may be especially beneficial where conventionally planted wetlands have failed due to erosion, high salt levels, low soil oxygen and other risks.

Scientists map source of Northwest's next big quake
The Cascadia Initiative deployed 70 seabed seismometers at 120 sites covering the entire Juan de Fuca plate to record mantle movement relative to the plate. Team members led by UC Berkeley have confirmed what geophysicists expected, but one surprise is that a small appendage called the Gorda Plate moves independently of the Juan de Fuca, apparently too light to influence the mantle flow 100 miles down. This could explain earthquake segmentation at the subduction zone.

Calcium-48's 'neutron skin' thinner than previously thought
An international team led by Gaute Hagen of the Department of Energy's Oak Ridge National Laboratory used America's most powerful supercomputer, Titan, to compute the neutron distribution and related observables of calcium-48, an isotope with an atomic nucleus consisting of 20 protons and 28 neutrons. Computing the nucleus from first principles revealed that the difference between the radii of neutron and proton distributions (called the 'neutron skin') is considerably smaller than previously thought.

Pineapple genome offers insight into photosynthesis in drought-tolerant plants
By sequencing its genome, scientists are homing in on the genes and genetic pathways that allow the juicy pineapple plant to thrive in water-limited environments. The new findings, reported in the journal Nature Genetics, also open a new window on the complicated evolutionary history of grasses like sorghum and rice, which share a distant ancestor with pineapple.

Bat disease fungus found to be widespread in northeast China
Bats in northeast China are infected with the fungus that causes white-nose syndrome, a deadly disease that has decimated bat populations in North America since it first appeared in upstate New York in 2006. A team of American and Chinese researchers found the fungus in caves where bats hibernate and found bats infected with the fungus.

Rapidly acidifying waters pose major threat for Southern Ocean ecosystem
A study published this week in the journal Nature Climate Change uses a number of Earth System Models to explore how the uptake of anthropogenic carbon dioxide and the resulting ocean acidification will affect the Southern Ocean over the next century. The new research finds that for some organisms the onset of such critical conditions will be so abrupt, and the duration of events so long, that adaption may become impossible.

Hypoxia-inducible factor-1 dependent nuclear entry of factor inhibiting HIF-1
Factor inhibiting HIF-1 (FIH-1) regulates hypoxia-inducible factor-1 (HIF-1) transcriptional activity by hydrolyzing asparagine at the C-terminus of HIF-1α, preventing the interaction between HIF-1α and associated cofactors and leading to suppressed activation of HIF-1. This action takes place in the nucleus but FIH-1 is a cytoplasmic protein. Itís now realized that the nuclear entry of FIH-1 is triggered by the transportation of HIF-1α from cytoplasm to the nucleus, a process that requires the presence of copper.

New concepts emerge for generating clean, inexpensive fuel from water
An inexpensive method for generating clean fuel is the modern-day equivalent of the philosopher's stone. One compelling idea is to use solar energy to split water into its constituent hydrogen and oxygen and then harvest the hydrogen for use as fuel. But splitting water efficiently turns out to be not so easy.

Study spells out why some insects kill their mothers
Among social insects, why does it pay for workers to help the queen in some situations but then also pay to kill her in others? What explains why some queens get killed and not others, and why kill her at all? Kevin Loope, a postdoctoral researcher at the University of California, Riverside, explored these questions, and found that by eliminating the queen, a matricidal worker frees the way for workers to lay male eggs.
