Iowa State University's Wintersteen talks partnerships at national science meeting

AMES, Iowa – Wendy Wintersteen, dean of Iowa State University's College of Agriculture and Life Sciences, spoke on Sunday of the importance of public-private partnerships in strengthening global food security during the annual meeting of the American Association for the Advancement of Science in Chicago.

During her talk, part of a panel on research and development for sustainable agriculture and food security, Wintersteen stressed the importance of partnerships in providing the innovation necessary to meet global challenges.

Deep ocean needs policy, stewardship where it never existed

BEAUFORT, N.C. -- Technological advances have made the extraction of deep sea mineral and precious metal deposits feasible, and the dwindling supply of land-based materials creates compelling economic incentives for deep sea industrialization. But at what cost?

Epigenetic regulation required to ensure correct number of chromosomes

Abnormal number of chromosomes is often associated with cancer development. In a new study published in the journal Nature Structural and Molecular Biology researchers at Karolinska Institutet in Sweden have shown that a subtle epigenetic change plays an important role in the correct segregation of chromosomes.

New blood cells fight brain inflammation

Hyperactivity of our immune system can cause a state of chronic inflammation. If chronic, the inflammation will affect our body and result in disease. In the devastating disease multiple sclerosis, hyperactivity of immune cells called T-cells induce chronic inflammation and degeneration of the brain. Researchers at BRIC, the University of Copenhagen, have identified a new type of regulatory blood cells that can combat such hyperactive T-cells in blood from patients with multiple sclerosis.

Scientists call for new stewardship of the deep ocean: Earth's last frontier

The deep ocean, the largest domain for life on earth, is also its least explored environment. Humans are now encroaching more vigorously than ever into the ocean's deep regions, exploiting the deep's resources and placing its wealth of vibrant habitats and natural services for the planet at risk.

Worldwide study finds that fertilizer destabilizes grasslands

Lincoln, Neb., Feb. 17, 2014 -- Fertilizer could be too much of a good thing for the world's grasslands, according to study findings to be published online Feb. 16 by the journal Nature.

The worldwide study shows that, on average, additional nitrogen will increase the amount of grass that can be grown. But a smaller number of species thrive, crowding out others that are better adapted to survive in harsher times. It results in wilder swings in the amount of available forage.

Study on flu evolution may change textbooks, history books

A new study reconstructing the evolutionary tree of flu viruses challenges conventional wisdom and solves some of the mysteries surrounding flu outbreaks of historical significance.

CU-Boulder stem cell research may point to new ways of mitigating muscle loss

New findings on why skeletal muscle stem cells stop dividing and renewing muscle mass during aging points up a unique therapeutic opportunity for managing muscle-wasting conditions in humans, says a new University of Colorado Boulder study.

Archaeologists lend long-term perspective to food security and climate shock

CHICAGO – What role does pre-existing vulnerabilities play for people who experience a climate shock? Does it amplify the effects of the climate shock or is effect negligible? Four Arizona State University archaeologists are looking into this as part of an international team examining how people can be most resilient to climate change when it comes to food security.

Research on urban ghettos must recognize differences among cities

Research on urban neighborhoods must take into account differences among cities and rely on some techniques that have not been used extensively by sociologists studying neighborhood effects, according to Mario Small, professor of sociology at the University of Chicago.

Small, who is also dean of UChicago's Division of the Social Sciences, studies urban neighborhoods and has studied the diversity of experiences for people living in poor neighborhoods in cities across the country.

Making biodiverse agriculture part of a food-secure future

Is biodiverse agriculture an anachronism? Or is it a vital part of a food-secure future?

Given the need to feed an estimated 2.4 billion more people by the year 2050, the drive toward large-scale, single-crop farming around the world may seem inexorable.

But there's an important downside to this trend, argues Timothy Johns, Professor of Human Nutrition at McGill University in Montreal, in a paper to be presented Saturday, Feb. 15, at the annual meeting of the American Association for the Advancement of Science in Chicago.

The new Africa -- green shoots in biosciences

Cambridge UK, Feb 10, 2014: This key session will bring African experts in person to Chicago to report on how agricultural biotechnology is starting to have a real impact on the crucial smallholder farming sector in particular. However, the session will also warn that this fledgling bioscience revolution needs to be carefully nurtured. According to moderator Sir Brian Heap, African economies are now among the fastest growing in the world. "While many of the world's farmers have benefitted from advances in bioscience, African farmers and citizens could possibly benefit the most.

Arizona State researcher explores responsible innovation

CHICAGO – An engineer works in the lab on a promising research project. He follows all the rules, works with the materials available to him and produces quality work. He never lies, cheats or steals. His research eventually results in a new technological innovation. Everybody wins.

But five or 10 years down the road, a byproduct of that new technology proves to be harmful to the environment. What if this unintended consequence could have been easily avoided had the engineer made a simple change in his research process?

LGB individuals living in anti-gay communities die early

February 12, 2014 -- In the first study to look at the consequences of anti-gay prejudice for mortality, researchers at Columbia University's Mailman School of Public Health found that lesbian, gay, and bisexual (LGB) individuals who lived in communities with high levels of anti-gay prejudice have a shorter life expectancy of 12 years on average compared with their peers in the least prejudiced communities.

High frequency of EGFR mutations found in Asian population

DENVER – Adenocarcinoma histology, female sex, never-smoking status, and Asian ethnicity have been considered the most important factors associated with EGFR mutations in non-small cell lung cancer and response to EGFR inhibitors. A recent study has found that, within the Asian population, the frequency of EGFR mutations associated with other demographic and clinical characteristics is higher than previously reported, even in patients with a history of smoking, suggesting that mutation testing should be done on a broader basis among Asian patients with advanced adenocarcinoma of the lung.
