Our current understanding of the Universe includes the rather unsettling notion that most of its matter is not luminous - it does not clump into stars, that is. Nobody has a clue of what this Dark Matter (DM) really is, and hypotheses on what it could be made of are sold at a dime a dozen. 
On the other hand, we clearly see the gravitational effects of DM on galaxies and clusters of galaxies, so the consensus of the scientific community is that one of those cheap theories must be true. What make this very close to a dream situation for an experimental scientist is the fact that we do have instruments capable of detecting, or ruling out, dark matter behaving according to most of the majority of those possibilities. 

The Morrison government has introduced new legislation responding to recent protests by animal rights activists in Australia. The bill –named The Criminal Code Amendment (Agricultural Protection) Bill 2019 – will tighten up existing laws, creating harsher penalties for those who incite others to trespass on farms.

Minister for Agriculture Bridget McKenzie and Attorney-General Christian Porter have said this legislation will deliver on the government’s

Symptoms of physician burnout appear to be associated with greater bias toward black people in this study of nearly 3,400 second-year resident physicians in the United States who identified as nonblack.

However, since this is simply an observational study it cannot determine if the suggested association between symptoms of burnout and bias toward black people is causal and the magnitude of the observed association was small to medium.

The Miocene pillow basalts from the Lake Roosevelt National Recreation Area of central Washington hold an unlikely fossil mold of a small rhinoceros, preserved by sheer chance as it's bloated carcass sunk to the bottom of a shallow pool or lake just prior to a volcanic explosion. We've known about this gem for a long while now. The fossil was discovered by hikers back in 1935 and later cast by University of California paleontologists in 1948.

Quintus Sertorius, a Roman statesman come general, grew up in Umbria, the green heart of what is now central Italy.

Born into a world at war just two years before the Romans sacked Corinth to bring Greece under Roman rule, Quintus lived much of his life as a military man far from the hills, mountains, and valleys of his birthplace. In 81 BC, he traveled to Morocco, the land of opium, massive trilobites and the birthplace of Antaeus, the legendary North African ogre who was killed by the Greek hero Heracles.

The Earth has a magnetic field with north and south poles. The magnetic field of the Earth is surrounded by the magnetosphere that keeps most of the particles from the Sun from hitting the Earth.

Have you ever wondered about the colors you see in these moments? What sunlight actually is? Yes, it's light from the Sun but so much more than that. Sunlight is both light and energy. Once it reaches Earth, we call this energy, "insolation," a fancy term for solar radiation. The amount of energy the Sun gives off changes over time in a never ending cycle. Solar flares (hotter) and sunspots (cooler) on the Sun's surface impact the amount of radiation headed to Earth.

A new position statement suggests resistance training should be considered vital to improving the health and longevity of senior citizens.

The statement makes recommendations for successful resistance training, or exercise focused on building muscle endurance, programs for older adults. 

When you poll people about living past 100 years old, few respond positively. It could be loss of friends and family, physical and cognitive decline, loss of independence and poor quality of life. If physical decline were mitigated, people may not be able to live longer, but they might live better.

The most popular organic fertilizer is feces while the most popular pesticide is copper sulfate. Both of those don't sound great to ingest but a new study says that extra dung leads to more bacteria - and that may be a good thing, if you believe a lot more bacteria is beneficial to gut health.

Yogurt marketing and supplement claims aside, there is no evidence that your body is impacted by probiotics unless you suffered a legitimate medical issue (as in you need an actual fecal transplant), yet like gluten-free diets probiotic foods have become a trend among people with extra money to spend. The same people who buy organic food.

During the early Triassic period, ichthyosaurs evolved from a group of unidentified land reptiles that returned to the sea. They were particularly abundant in the later Triassic and early Jurassic periods before being replaced as premier aquatic predator by another marine reptilian group, the Plesiosauria, in the later Jurassic and Cretaceous periods.
