Modern food science has meant a lot fewer people starving, but there has also been an increase in products designed to keep animals and fish healthy, like antibiotics.

Antibiotics do not just disappear. Even in trace amounts, over time they can build up in the environment and that gives bacteria another path to developing resistance.

In a new study, PhD candidate Hansa Done and Dr. Rolf Halden, PhD of Arizona State University's Biodesign Institute, examine antibiotic use in the rapidly expanding world of global aquaculture. They measured the presence of antibiotics in shrimp, salmon, catfish, trout, tilapia and swai, originating from 11 countries. Data showed traces of 5 of the 47 antibiotics evaluated.

Ancient Greeks used onions as a performance-enhancing drug. Roman gladiators ate ashes and vegetables. If common-sense does not tell us that there was no ancient civilization with futuristic technology building pyramids, anthropology certainly can.

Historic sources claimed referred to gladiators  as "hordearii" ("barley eaters") because they had an inferior diet, heavy in beans and grains, the hallmark of poor status. Even 2,000 years ago people made fun of vegetarians, it seems. Though the diet was accurate, it was not all special, according to a new paper.

The surface of Venus can't be seen from orbit in visible light due to its hot, dense and cloudy atmosphere. Instead, radar has been used by spacecraft to penetrate the clouds and map out the surface – both by reflecting radar off the surface to measure elevation and by looking at the radio emissions of the hot surface. The last spacecraft to map Venus that way was Magellan, two decades ago. 

One of the Venusian surprises discovered at that time is that radio waves are reflected differently at different elevations on Venus. Also observed were a handful of radio dark spots at the highest elevations. Both enigmas have defied explanation.

Human parainfluenza virus (hPIV) is highly infectious and the leading cause of upper and lower respiratory tract disease in young children, including Croup, which is responsible for thousands of hospitalizations in the developed world, and hundreds of thousands of deaths each year in developing countries.

Director Professor Mark von Itzstein said his Group's research findings published in Nature Communications today provide a new direction towards the discovery of anti-viral drugs against hPIV.

It is often believed that masculine men and more feminine women were prized in ancient societies and that modern culture is beyond gender simplifications, but a
team of psychologists, anthropologists and biologists that surveyed 12 populations around the world, from the primitive to the highly developed, find that isn't so.

How did life originate? And can scientists create life? These questions have always occupied philosophers and scientists interested in the origin of life, and they impact technology of the future also.

If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.

Protocells are the simplest, most primitive living systems, you can think of. The oldest ancestor of life on Earth was a protocell, and when we see, what it eventually managed to evolve into, we understand why science is so fascinated with protocells. If science can create an artificial protocell, we get a very basic ingredient for creating more advanced artificial life.
