Storks Could Be Poisoned By Pesticides During Migration To Africa

Science2.0 - March 1, 2015 - 2:10am

Not all storks migrate to Africa, many spend the winter in the Iberian Peninsula, where landfills have become a permanent source of food. Scientists from Extremadura have analyzed the presence of pollutants and pesticides (some prohibited in Spain) in the blood of nestlings from three colonies, two of which are close to landfill sites, and the results reveal that the main source of contamination can be due to the use of insecticides still used in African countries where the birds migrate to, who transfer their contaminated load onto their offspring through their eggs.

Tagging Drugs To Stop Counterfeit Medicine

Science2.0 - March 1, 2015 - 2:10am

The U.S. and other countries are enacting rules to clamp down on the sales of fake pharmaceuticals, which pose a public health threat. But figuring out a system to track and authenticate legitimate drugs still faces significant obstacles, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

Good Sleep Keeps Your Stem Cells Young

Science2.0 - February 28, 2015 - 10:29pm

Under normal conditions, many of the different types of tissue-specific adult stem cells, including hematopoietic stem cells, exist in a state or dormancy where they rarely divide and have very low energy demands. "Our theory was that this state of dormancy protected hematopoietic stem cells from DNA damage and therefore protects them from premature aging," says Dr. Michael Milsom, leader of the study.

Agriculture Expansion In Tanzania May Increase Plague Risk

Science2.0 - February 28, 2015 - 10:29pm

The push to boost food production in East Africa that is accelerating the conversion of natural lands into croplands may be significantly increasing the risk of plague according to a new study in the American Journal of Tropical Medicine and Hygiene.

Airport Screening For Viruses Misses Half Of Infected Travelers

Science2.0 - February 28, 2015 - 8:13pm

In the past decade, the H1N1 virus and Ebola are just two of the diseases whose spread was spurred by international airline travel. Screening passengers at airports, therefore, could be one key method for slowing the global spread of infectious diseases.

A team lead by UCLA researchers has found that airport screening misses at least half of infected travelers but the scientists say that rate could be improved. Their research was published in eLife. The life scientists used a mathematical model to analyze screening for six viruses: the SARS coronavirus, the Ebola virus, the Middle East respiratory syndrome coronavirus, the Marburg virus, Influenza H1N1 and Influenza H7N9.

Inequalities In Aging As Government Encourages Us To Work Longer

Science2.0 - February 28, 2015 - 8:13pm

Changes in pension and employment policies are making it increasingly necessary for older people in the UK to work beyond the age of 65. However, new research from the University of Surrey finds significant differences in the likelihood of employment and income levels of people beyond 65, depending on their gender and health.

Years of healthy life expectancy and the likelihood of disability in older age vary significantly, and as a result particular groups are going to find it hard to keep working beyond 65 and are more likely to be disadvantaged by a rise in the state pension age, than others.

Science 2.0: Node Prominence Profile And Degree Centrality In Networks

Science2.0 - February 28, 2015 - 6:36pm
Centrality and nodes are an important concept in the theory of social networks. Centrality of an individual - a "node" in network theory - measures its relative importance within a network, and a recent paper in Scientific Reports studies the problem of dynamics and evolution of node's centrality.

Nitesh Chawla, Associate Professor of Computer Science at the University of Notre Dame, and doctoral students Yang Yang and Yuxiao Dong point out that social networks are dynamic and evolve over time when new individuals (nodes) join a network, or new links form between nodes or old links diminish between nodes. A node's centrality may change over time.

Cats Use Sight Over Smell When Finding Food

General - February 28, 2015 - 2:30pm
Cats seem to use their eyes rather than follow their nose when it comes to finding the location of food, according to a new paper by animal behaviorists.

Felines have keen smell and vision, so a small study investigated which sense they prefer to use under test conditions – and suggests sight may be more important than smell.

A group of six cats were placed in a maze which had ‘decision’ points – and the cats had to choose which avenue they took based on their preference for using images or smell. They were simultaneously presented with two squares of paper, each containing a different visual and odour cue. One combination of stimuli indicated they would receive a food reward, whereas the other led to no reward.

Hormone Therapy In Transgender Adults Safe

Science2.0 - February 28, 2015 - 2:13pm

In the most comprehensive review to date addressing the relative safety of hormone therapy for transgender persons, researchers from Boston University School of Medicine (BUSM) have found that hormone therapy in transgender adults is safe. The findings, which appear in the Journal of Clinical and Translational Endocrinology, may help reduce the barriers for transgender individuals to receive medical care.
