People tend to associate the ability to think creatively with stereotypical masculine qualities, according to a paper in Psychological Science, which suggests that the work and achievements of men tend to be evaluated as more creative than similar work and achievements produced by women.

Research suggests that when people think about "creative thinkers" they tend to think of characteristics typically ascribed to men but not women, including qualities like risk-taking, adventurousness, and self-reliance. Lead author Devon Proudfoot of the Fuqua School of Business at Duke University and colleagues Aaron Kay and Christy Zoval hypothesized that this could ultimately lead people to view creative thinking as an ability more common among men than women.

A new analysis leads the authors to advance the belief that viruses are living entities that share a long evolutionary history with cells, based on a method for tracing viral evolution back to a time when neither viruses nor cells existed in the forms recognized today.

Until now, viruses have been difficult to classify, said University of Illinois crop sciences and Carl R. Woese Institute for Genomic Biology professor Gustavo Caetano-Anollés, who led the new analysis with graduate student Arshan Nasir. In its latest report, the International Committee on the Taxonomy of Viruses recognized seven orders of viruses, based on their shapes and sizes, genetic structure and means of reproducing.

Patients with advanced gastrointestinal neuroendocrine tumors (NETs) have limited treatment options and there are few oncologists who are specialized in this relatively rare disease. But now results from a multi-center randomized international trial of an innovative treatment show a marked improvement in the length of time patients with mid-gut NETs live without the disease getting worse (progression-free survival, or PFS), researchers reported to the 2015 European Cancer Congress.

Current national guidelines on the diagnosis of miscarriage may still be associated with misdiagnoses, and should be reviewed in light of new evidence, suggests a study published in The BMJ today.

The Royal College of Obstetrics and Gynaecologists (RCOG) guidelines recommend a miscarriage diagnosis based on an ultrasound scan measurement of the gestational sac diameter (GSD) and the embryo's crown-rump length (CRL).

Guidelines on the cut off values for these measurements were updated in 2011 following concerns that the older recommendations were based on inadequate evidence and leading to misdiagnoses. These changes have been shown to be safe, according to a new study by Professor Tom Bourne at Imperial College London and colleagues.

Last Friday I was invited by the University of Padova to talk about particle physics to the general public, in occasion of the "Researchers Night", a yearly event organized by the European Commission which takes place throughout Europe - in 280 cities this year. Of course I gladly accepted the invitation, although it caused some trouble to my travel schedule (I was in Austria for lectures until Friday morning, and you don't want to see me driving when I am in a hurry, especially on a 500km route).

Black rice has a rich cultural history; called "Forbidden" or "Emperor's" rice, it was reserved for the Emperor in ancient China and used as a tribute food. In the time since, it remained popular in certain regions of China and recently has become prized worldwide for its high levels of antioxidants.

Despite its long history, the origins of black rice have not been clear. Black rice cultivars are found in locations scattered throughout Asia. However, most cultivated rice (species Oryza sativa) produces white grains, and the wild relative Oryza rufipogon has red grains.

The expert report underpinning the latest dietary guidelines for Americans fails to reflect much relevant scientific literature in its reviews of crucial topics and therefore risks giving a misleading picture.

Concern about the report has prompted the US Congress to schedule a hearing on the guidelines in October, when two cabinet secretaries are scheduled to testify, writes journalist Nina Teicholz in an article published today.

At a Chevron oil refinery in Hawaii, researchers are growing microalgae in a 5,000-liter photobioreactor, flowing wastewater from the refinery through the reactor, and taking advantage of the algae's appetite for chemical nutrients to polish the water, removing noxious chemicals, including 90% of the ammonia-nitrogen and 97% of the phosphorus.

As the microbes feed, they grow and multiply, providing a wealth of algae-based biomass for producing bioenergy and high-value biobased chemicals and specialty products, as described the article "Algae-Mediated Valorization of Industrial Waste Streams" in Industrial Biotechnology.

If you live in Indiana, or at least near Indianapolis, you should go to the Celebrate Science Indiana science festival in the Blue Ribbon Pavilion at the Indiana State Fairgrounds Saturday 3 October 2015 from 9:30am-5:30pm—it’s free.

As much as 47 percent of the edible U.S. seafood supply is lost each year, mainly from consumer waste, according to a paper in Global Environmental Change, which takes advantage of a recent spotlight on the sustainability of the world's seafood resources.

 The 2010 U.S. Dietary Guidelines recommended increasing seafood consumption to eight ounces per person per week and consuming a variety of seafood in place of some meat and poultry. Yet achieving those levels would require doubling the U.S. seafood supply, which could threaten the global seafood supply if more farming and less waste are not considered.
