Researchers in Scientific Reports are claiming the first non-human instance of an animal possessing some mental states (e.g., mental body image, standards, intentions, goals), which are elements of private self-awareness.

They show that Labroides dimidiatus (bluestreak cleaner wrasse) checked their body size in a mirror before choosing whether to attack fish that were slightly larger or smaller than themselves. 

The authors say the cleaner wrasse’s behavior of going to look in the mirror installed in a tank when necessary indicated the possibility that the fish were using the mirror to check their own body size against that of other fish and predict the outcome of fights.

In 1929, an experiment with 28 barley varieties showed why barley, one of the world’s most important cereal crops for at least 12,000 years, has been so adaptable, growing everywhere from Norway to the mountains of South America, and why that means the future remains bright for whiskey and beer.

In most cases, random changes to DNA allowed it to survive in each new location so scientists nearly 100 years ago set out to discover the genes that changed to predict which varieties will thrive in which places. Modern work is highlighting for media its implications in a world of future climate change but nothing happening now compares to the rain and drought booms and busts of the past.

Influences buoyed by epidemiological claims about gimmick diets can make fitness intimidating but ignore them. Even if you don't lose weight, if you exercise your belly fat is still going to be healthier than someone who does nothing.

It just takes some consistency. 

Robots have a 200-year-old problem: motors. Even walking robots feature arms and legs that are powered by motors and that is a barrier to helping the living but a new muscle-powered robotic leg can jump and move and fast while detecting and reacting to obstacles. 

Mars is no vacation paradise. The temperatures fluctuate dramatically and average minus 80 degrees Fahrenheit. The surface is red dust punctuated by craters, canyons, and volcanoes. On the plus side, the atmosphere is extremely thin, comprising only about 1% of the density of Earth’s, and gravity is 60 percent lower, so you can finally dunk a basketball.

With all of those challenges, Martian landers have still been able capture wind measurements — some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image “tell-tales” that blow in the wind. Both anemometric methods have yielded valuable insight into the planet’s climate and atmosphere.

If humans ever intend to go there, we'll need more data first.

Alcohol is the best-marketed carcinogen out there. Cigarettes and obesity only wish they were able to devote the money to positive imaging that alcohol, one of the top three lifestyle killers, receives. Instead, governments devote billions to education and awareness of those two while the only tepid warning about alcohol is not to drive after you roll the dice on cancer.

When it comes to BPA, PFAS, or weedkillers, government epidemiologists say any presence should be considered pathological but say nothing at all about alcohol use despite it being scientifically shown, unlike most epidemiology, and addictive.
