At 2 AM local time in Hawaii, Tropical Storm Ana was just below hurricane strength with maximum sustained winds near 70 mph.

NOAA's Central Pacific Hurricane Center expects it to weaken before it intensifies again. The center of tropical storm Ana was located near latitude 20.6 north and longitude 162.6 west. That puts the center of Ana about 225 miles (360 km) west-southwest of Lihue Hawaii and about 325 miles (525 km) southeast of French Frigate Shoals.

Ana is moving toward the west near 9 mph (15 kph) and is expected to gradually turn to the northwest.  

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.

A long-distance optical tractor beam can move tiny particles - one fifth of a millimeter in diameter - a distance of up to 20 centimeters, which is almost 100 times further than previous experiments.

The hollow laser beam is bright around the edges and dark in its center and it can be used to attract or repel objects.

Get ready to control the weather or capture an X-Wing fighter in space - if it's really close, that is.

Is fairness built into the brain? According to a new Norwegian brain paper, people appreciate fairness - but fairness is not that everybody gets the same income, which is sure to concern those who believe all money should be distributed equally.

Economists from the Norwegian School of Economics and brain researchers from the University of Bergen decided to try and assess the relationship between fairness, equality, work and money: how brains react to how income is distributed.

The team looked at the striatum - the "reward center" of the brain. By measuring reaction to questions related to fairness, equality, work and money, they believe they can find answers about how we perceive distribution of income.

Anti-inflammatory medicines such as aspirin, estrogen, and Fluimucil can improve the efficacy of existing schizophrenia treatments, according to results announced at the European College of Neuropsychopharmacology conference in Berlin.

Doctors have long believed that helping the immune system may benefit the treatment of schizophrenia, but until now there has been no conclusive evidence that this would be effective. Now a group of researchers at the University of Utrecht in the Netherlands has carried out a comprehensive meta-analysis of all robust studies on the effects of adding anti-inflammatories to antipsychotic medication. They conclude that anti-inflammatory medicines, such as aspirin, can add to the effective treatment of schizophrenia.
