Democratizing data visualization

In 2007, members of the Haystack Group in MIT's Computer Science and Artificial Intelligence Laboratory released a set of Web development tools called "Exhibit." Exhibit lets novices quickly put together interactive data visualizations, such as maps with sortable data embedded in them; sortable tables that automatically pull in updated data from other sites; and sortable displays of linked thumbnail images.

Students on field course bag new spider species

As a spin-off (pun intended) of their Tropical Biodiversity course in Malaysian Borneo, a team of biology students discover a new spider species, build a makeshift taxonomy lab, write a joint publication and send it off to a major taxonomic journal.

The first insects were not yet able to smell well

An insect's sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, many proteins involved in the highly sensitive odor perception of insects emerged rather late in the evolutionary process.

One gene, many tissues

Genes are the "code" for building the biological elements that form an organism. The DNA that makes up genes contains the instructions to synthesise proteins, but it's wrong to think that, for a given gene, these instructions are always the same for all parts of the organisms. In actual fact, the gene varies depending on the tissue where it is located (cerebral cortex, cerebellum, olfactory epithelium, etc.); in particular, what varies is the point in the "string" of code at which protein synthesis starts.

Decline of natural history troubling for science, society

Support for natural history – the study of organisms, how and where they live and how they interact with their environment – appears to be in steep decline in developed countries, according to Joshua Tewksbury, a University of Washington professor and WWF International scientist.

"Yet natural history provides essential knowledge for fields as varied as human health, food security, conservation, land management and recreation," he said.

One size does not fit all: Dietary guidelines for choline may be insufficient

What is now considered to be the "right" amount of the essential nutrient, choline, might actually be "wrong," depending on who you are. That's because scientists have found that the "right" amount of choline needed by an individual is influenced by a wide range of factors, including gender, life stage, race and ethnicity of the individual. This means that using the current one-size-fits-all approach to determining a person's vitamin and mineral needs may leave them in less than optimal health.

Gen X obesity a major problem for healthcare, workforce

Researchers at the University of Adelaide have confirmed that if current trends continue, Australia's Generation X will overtake Baby Boomers for poor health, including rates of obesity and diabetes, which could have huge implications for healthcare and the workforce.

How size splits cells

One of the scientists who revealed how plants "do maths" can now reveal how cells take measurements of size. Size is important to cells as it determines when they divide.

In a paper published in eLife, Professor Martin Howard from the John Innes Centre and colleagues from the US, Germany and Singapore discovered that cells measure their surface area using a particular protein, cdr2p. The finding challenges a previous model suggesting that another protein called pom1p senses a cell's length.

Natural plant compounds may assist chemotherapy

Auckland, New Zealand. 27 March 2014...Researchers at Plant & Food Research have identified plant compounds present in carrots and parsley that may one day support more effective delivery of chemotherapy treatments.

Strictly yeast

We all know yeasts make beer and bread but their huge contribution to science, including helping us understand the nuts and bolts of life itself, tends to stay out of the spotlight. Over the past few years, through studies carried out on yeast DNA, biologists have begun to learn that something that looks like a simple cog in all living things is actually performing an intricately choreographed dance. In the same way that the Charleston differs from the Waltz, the dance displayed by this cog is faster and uses different steps from other parts of the yeast machinery.

Smoke-free air policies seem to protect the heart

WASHINGTON (March 27, 2014) — A new study on the impact of Michigan's statewide smoking ban adds to mounting evidence that policies prohibiting tobacco smoking in workplaces and other public spaces may substantially improve public health by reducing heart disease and death, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

Cholesterol levels vary by season, get worse in colder months

WASHINGTON (March 27, 2014) — Cholesterol levels fluctuate based on the time of year with more unfavorable lipid profiles seen in the colder months, a trend that may be driven by related behavior changes, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

Mediterranean diet may lower risk of diabetes

WASHINGTON (March 27, 2014) — Adoption of a Mediterranean diet is linked to a lower risk of diabetes, especially among people at high risk for cardiovascular disease, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

Marathon training could help the heart

WASHINGTON (March 27, 2014) — Marathon training is associated with improved risk factors related to cardiovascular disease among middle-aged recreational male runners, suggesting that race preparation may be an effective strategy for reducing heart disease risk, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

Air pollution from traffic increases odds of hospital readmission for asthma

Higher exposure to traffic-related air pollution (TRAP) dramatically increases the odds of readmission to the hospital for asthma – but only for white children, according to a new Cincinnati Children's Hospital Medical Center study.

The study shows that white children exposed to high levels of TRAP are three times more likely to be readmitted for asthma than white children with low TRAP exposure. Levels of TRAP exposure were not associated with increased risk of readmission of black children, despite their having overall higher rates of asthma readmission than white children.
