Deep inside the largest and deepest gold mine in North America scientists are looking for dark matter particles and neutrinos instead of precious metals.

This is an internet joke event. Lots of people saying they will go just for the fun of it. Out of those 500,000 or more, it would be a surprise if 50 actually turn up. This is what they plan to do, a Naruto run (the bit at the end of this video about anime being illegal is a joke).

This may help with this and other fake asteroid news. It's a no hazard asteroid. There is no NASA warning at all. They have already removed 88 "no hazard" asteroids from their table so far this year.It's 11 million to one against, and it's like rolling 9 or 10 dice and getting a six every time.

An object this size hits only every 94,000 years. They search for them so that they can warn us if they are going to hit. With a warning then we can either deflect it or evacuate the impact zone. There is no warning for this one.

This is being reported in a way that scares some people But this is not new climate research, and changes nothing about the 2018 IPCC report. It is just a public education paper, helping people to understand the consequences of climate change, and evaluate environmental policies. It could have been written any time in the last decade and would have been essentially the same with minor tweaks.

Do you feel like nutritionists are always changing their minds? Do you want science-based information about diet but don’t know whom or what to believe?

If you’re nodding in agreement, you’re not alone: More than 80% of Americans are befuddled.

Yet it’s a lament that’s getting quite tiring – if you’re a nutrition scientist, that is. So much so that I refocused my career to shine scientific light on today’s critical food conversations, which have profound impacts on public health and the environment. My mantra: From farm to fork, what we eat matters.

This fellow is the graptolite, Isograptus cf. maximus, from the Piranha Formation, Middle Ordovician (Dapingian), Bolivia.

“When the tide is out, the table is set.” This wisdom from those who call Haida Gwaii home is still true today. The enormous difference between high and low tide in Haida Gwaii – up to twenty three vertical feet – means that twice a day, vast swathes of shellfish are unveiled, free for the taking.

Archaeological evidence tells us that by roughly five thousand years ago, gathering shellfish replaced hunting and fishing as a primary food source on the islands. The shellfish meat was skewered on sticks, smoked and stored for use in winter or for travel.

 
If you're lucky enough to swim in the warm, shallow waters of the Indo-Pacific region, you may encounter one of the most charming of all the sea stars, the Protoeaster nodosus. These beauties are commonly known as Horned Sea Stars or, my personal favorite, Chocolate Chip Sea Stars.

A recent review of meta-analyses and 277 randomized controlled trials--in which nearly 1 million adults participated--to find out how various nutritional supplements and diets influenced mortality rates and cardiovascular outcomes found...not much.

Most people use toothbrushes, toothpaste and dental floss to clean their teeth, but their use is by no means universal. Many indigenous groups, as well as people in developing countries, use traditional techniques to clean their teeth. Some of these techniques are more effective than others.

Many people in the Middle East, and some parts of South and Southeast Asia, use twigs from the arak tree (known as miswak) to clean their teeth. They fray the end of the twig, dampen the resulting bristles with water or rosewater and then rub the bristles against their teeth (see video below). The wood of the arak tree (Salvadora persica) has a high concentration of fluoride and other antimicrobial components that prevent tooth decay.
