Study casts doubt on climate benefit of biofuels from corn residue
Biofuels made from corn stover -- stalks, leaves and cobs that remain after harvest -- appear to emit more carbon dioxide over their life cycle than federal standards allow, according to research led by Adam Liska, assistant professor of biological engineering at the University of Nebraska-Lincoln.

Study of gut microbes, antibiotics: Clues to improving immunity in premature infants
Mothers give a newborn baby a gift of germs -- germs that help to kick-start the infant's immune system. But antibiotics, used to fight bacterial infection, may paradoxically interrupt a newborn's own immune responses, leaving already-vulnerable premature babies more susceptible to dangerous pathogens

Bulletproof nuclei? Stem cells exhibit unusual absorption property
Stem cells -- the body's master cells -- demonstrate a bizarre property never before seen at a cellular level, according to a study published today from scientists at the University of Cambridge. The property -- known as auxeticity -- is one which may have application as wide-ranging as soundproofing, super-absorbent sponges and bulletproof vests.

Cancer stem cells linked to drug resistance
Most drugs used to treat lung, breast and pancreatic cancers also promote drug-resistance and ultimately spur tumor growth. Researchers at the University of California, San Diego School of Medicine have discovered a molecule, or biomarker, called CD61 on the surface of drug-resistant tumors that appears responsible for inducing tumor metastasis by enhancing the stem cell-like properties of cancer cells.

'Chaperone' compounds offer new approach to Alzheimer's treatment
A team of researchers from Columbia University Medical Center, Weill Cornell Medical College, and Brandeis University has devised a wholly new approach to the treatment of Alzheimer's disease involving the so-called retromer protein complex. Retromer plays a vital role in neurons, steering amyloid precursor protein (APP) away from a region of the cell where APP is cleaved, creating the potentially toxic byproduct amyloid-beta, which is thought to contribute to the development of Alzheimer's.

Religious music brings benefit to seniors' mental health
A new article published online in The Gerontologist reports that among older Christians, listening to religious music is associated with a decrease in anxiety about death and increases in life satisfaction, self-esteem, and sense of control over their lives. In particular, listening to gospel music is associated with a decrease in anxiety about death and an increase in sense of control.

Researchers find 3-million-year-old landscape beneath Greenland ice sheet
Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything -- vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland ice sheet, below two miles of ice.

Sun emits a mid-level solar flare
The sun emitted a mid-level solar flare, peaking at 9:03 a.m. EDT on April 18, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

Researchers question published no-till soil organic carbon sequestration rates
For the past 20 years, researchers have published soil organic carbon sequestration rates. Many of the research findings have suggested that soil organic carbon can be sequestered by simply switching from moldboard or conventional tillage systems to no-till systems. However, there is a growing body of research with evidence that no-till systems in corn and soybean rotations without cover crops, small grains, and forages may not be increasing soil organic carbon stocks at the published rates.

Finding turns neuroanatomy on its head
Harvard neuroscientists have made a discovery that turns 160 years of neuroanatomy on its head. Myelin, the electrical insulating material long known to be essential for the fast transmission of impulses along the axons of nerve cells, is not as ubiquitous as thought, according to a new work lead by Professor Paola Arlotta of the Harvard Stem Cell Institute, in collaboration with Professor Jeff Lichtman, of Harvard's Department of Molecular and Cellular Biology.

Plants with dormant seeds give rise to more species
Seeds that sprout as soon as they're planted may be good news for a garden. But in the wild, a plant whose seeds sprouted at the first warm spell or rainy day would risk disaster. More than just an insurance policy against late frosts or unexpected dry spells, it turns out that seed dormancy has long-term advantages too: plants whose seeds put off sprouting until conditions are more certain give rise to more species.

Ancient DNA offers clues to how barnyard chickens came to be
Ancient DNA adds a twist to the story of how barnyard chickens came to be, finds a study to be published April 21 in the journal PNAS. Analyzing DNA from the bones of chickens that lived 200-2,300 years ago in Europe, researchers report that some of the traits we associate with modern domestic chickens -- such as their yellowish skin -- only became widespread in the last 500 years, much more recently than previously thought.
