Dark Matter (DM), the mysterious substance that vastly dominates the total mass of our universe, is certainly one of the most surprising and tough puzzles of contemporary science. We do not know what DM is, but on the other hand we have a large body of evidence that there must be "something" in the universe that causes a host of effects we observe and which would have no decent explanation otherwise.
We have been sending missions to Mars since the Mariner 4 flyby in 1964, and our first successful landing was Viking 1 in 1976, So, why can't astrobiologists answer the question definitively, when you ask them if there is life on Mars?
Well, perhaps it's because we haven’t looked.
You might think,
To observers in much of North America and East Asia, on January 31st, the second full moon of the month, passed through Earth’s shadow in a Super Blue Blood Moon.
A few weeks ago, I came across a press release issued by the Health and Environment Alliance (HEAL), a European-based non-governmen
In the haze of smoke and mirrors about nutrition, it's easy to think that you will lose weight if you eliminate some scary chemicals (Endocrine Disruptors!™) or scary foods (Sugar! Dairy! Meat! High Fructose Corn Syrup! Grain! Gluten!) but the reality is much simpler: You just need fewer calories.
No, really. In 100 percent of studies, people who consumed fewer calories than they burned lost weight. Harvard Food Frequency Questionnaires, with their numerous outcomes and numerous foods, are guaranteed to come up with a food that will cause disease with a .05 p-value. That is how statistics work. It is probably why they chose so many foods for the first one and did even more later.
The Rosette Nebula is located in the Milky Way Galaxy roughly 5,000 light-years from us and is known for its rose-like shape and distinctive hole at the center. The nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases with several massive stars found in a cluster at its heart.
Claims of secret meetings and manipulation of the policy agenda. A split in government ranks, and threats to withdraw from a national review. It’s all just part and parcel of the latest round in the development of Australian animal welfare standards and guidelines, in this case proposed new standards for the poultry and egg industries.
If you have used voice-enabled speaker devices like the Amazon Echo, which for some reason goes by Alexa rather than Echo, you've noticed there are not a lot of great apps and most of them do very narrow things. They are more like public relations tools for brands.
Google is no better but companies insist it is the future, that is why Apple is getting into the game with Homepod. They all suffer from the problem that Apple created yet which is the trend, because if puts hundreds of billions of dollars in their bank account: They tell you what you want on their devices, and that's all you are going to get. You aren't smart enough to look through a free market and decide. So if they decide Lady Doritos really should be a thing, it's what you have.
Plant lovers love peat moss, it is the major component of potting mix and popular in greenhouses and gardens, but the 'back to nature' movement has caused it to be depleted faster than it can re-form, and it contributes to the release of carbon dioxide into the atmosphere.
Science may have the solution. Similar to charcoal, biochar is produced through a process called pyrolysis, or heating to high temperatures in the absence of oxygen. And like charcoal, it can be derived from virtually any organic substance. To save the peat moss, we have to burn some other stuff. But even then burning is better for emissions than runaway peat moss exploitation by the organic community.

So Elon Musk's Tesla roadster is now in an orbit that takes it right out to the asteroid belt not far from Ceres. And what a thrilling launch it was with the two boosters landing so perfectly choreographed. It was nearly flawless. Only one minor hiccup, that the core booster missed the barge and crashed into the water, probably at around 300 mph, scattering the barge with shrapnel. They will surely fix that too with future launches.
If any of you haven't seen it yet, here is the launch video archived by SpaceX.
