Read the World Scientists’ Warning of a Climate Emergency, a document signed by 11,000 scientists who regard it as their moral obligation to warn humanity of the catastrophic threats to planet Earth.

Astronomers recently found 20 new moons circling Saturn, all with a diameter of around 5 kms. With 82 known moons, the ringed planet surpasses Jupiter (with 79 moons) as the new Moon King.

Mindfulness training can enhance a person’s capacity to “unlearn fear”  to become less anxious about things you’ve been anxious about  in part through structural and functional changes involving the hippocampus.

Ancient reptilian hand muscles, thought to have disappeared from our human ancestors for 250 million years, were recently discovered in the first formations of a human embryo, which then get deleted before birth.

Climate change that caused a prolong drought in Europe has resurfaced a 7,000-year-old “Stonehenge” that disappeared 50 years ago with the damming of the Tagus River in Spain.

The awesome power of ocean waves is magnified in this short film by Chris Bryon, using state-of-the art camera work, and an artist’s eye for beauty.

Archeologists have studied the impacts of human habitation on the earth and concluded that significant changes to the environment started nearly 10,000 years ago. This map shows how intensive agriculture developed in that time.​

There are so many reasons to take action now for our world, including recent headlines that the Amazon Rainforest could self-destruct, the climate crisis is making people sicker, and that more than half of Greenland’s ice sheet’s surface started melting for the first time since 2012.

The Skyglow Project just put out an awesome new video, using the backdrop of a changing sky to tour North America’s indigenous petroglyphs and ruins.

This video shows how our knowledge of known exoplanets has grown exponentially in the last 30 years, from 2 in 1992 to 4,003 today!

Can plants think? One neuroscientist hooked up a Venus Flytrap to an EKG to show how plants can use electrical signals to process information, stimulate movement, and even compute time. Our kinship with all living things seems clearer than ever.

Cannonballs of the cosmos? This pulsar is spinning 8.7 times per second and hurtling through space at 2.5 million miles an hour. Astronomers say it’s traveling 5x faster than other pulsars and will eventually get propelled out of our galaxy.

A vast void in our cosmic neighborhood. Astronomers have discovered that our local Milky Way galaxy lies in the boundary between the Virgo cluster and a vast void of emptiness. A new study investigates how this Local Void influences the movement of our galaxy.

For a hundred years, humans have been broadcasting radio waves into the cosmos  and the bubble of reach has expanded to 200 light years distance today. But how big is that really? This image provides some insight.

A team of scientists examined 4 million years of our ancestry for clues to why our modern human faces evolved to look as they do today. Diet and climate were two major influences – and both may continue to reshape our appearance as earth’s climate warms.

Where were you 50 years ago when earthlings first stepped onto their moon? Last week was the half century milestone for this amazing event and it’s worth watching this video to reflect on how precarious the landing actually was.

Despite whatever woes currently avail us, the facts do show that humanity has made significant progress. This amazing video graph shows changes over the past 150 years in reducing child mortality worldwide.

Science rests on the view that objective facts exist. But in a recent experiment with entangled photons, researchers have concluded that two people can observe existing but contradictory facts at the quantum level. Yikes! Of course, at the level of atoms and molecules, let alone mice and moons, reality seems more reassuringly knowable.

Ever seen two galaxies dancing? Check out this cool image of two mighty galaxies currently pulling each other apart after passing through each other.

In their matriarchal society, bonobo moms help their sons meet and mate with eligible females to ensure their male offspring don’t get overlooked in the intensely competitive social order. Their success rate is three times higher due to this maternal support.

Researchers have determined that trauma in childhood (including poverty and stressful events) accelerates puberty and brain maturation, with potentially greater mental health disorders into adulthood.

Some in the animal kingdom prove that art is greater than smart! This puffer fish, though dull in appearance, creates beautiful mandalas to attract his mate.

The vastness of the universe is incomprehensible to the human mind, yet that doesn’t stop astronomers from trying. This video uses a grain of sand as a measurement unit for imagining the relative size of our cosmos.

Why do days – and years – seem shorter as we get older? Research suggests this phenomenon occurs in aging human brains, which process information at a slower rate. Because older brians view fewer new images in the same amount of actual time as younger ones, time seems to pass more quickly.

This very cool virtual flyby of the Whirlpool galaxy uses data and images from the Hubble Space Telescope. It helps us visualize what a galaxy very similar to ours might look like if we could fly at the speed of light!

A team at John Hopkins have come up with a new theory to help answer one of astromony’s more puzzling questions: why the universe seems to be expanding faster than it should be. Could an early form of dark energy cause the universe to speed up from time to time? And why?

When China stopped importing trash last year, much of what used to get recycled now ends up in landfills. Until the current “recycling crisis” gets resolved, there are resources to help continue your efforts to recycle and reduce waste.

The U.S. ranking at #19 in the 2019 World Happiness Report could be related to income inequality, technology and other addictions, as well as ineffective government. Another study found that countries low on the happiness scale tend to vote against incumbent leaders, and that election results can make a nation happier.

After nearly two years and hundreds of intertwining stories, the Special Counsel’s report on the investigation into Russian interference in the 2016 U.S. elections will be released this week. Here’s a guide to unravel the tangle of stories and subplots.

In 1925, Werner Heisenberg developed a new formulation for classical quantum physics. Fifty years later, Fritjof Capra expanded on Heisenberg’s Matrix Mechanics in The Tao of Physics, which helped to establish a profound shift in our understanding of the material world: “not a collection of separate objects, but rather appears as a network of relations between the various parts of a unified whole.” Thanks to Dale Medearis for this entry!

In a joint American/Dutch project, The Ocean Cleanup was launched in September 2018 to rid the ocean of plastic in the Great Pacific Garbage Patch, 1,200 nautical miles offshore. An update report from last week recounts both its successes and failures in the first months of operation.

One of the most mind-blowing theories in theoretical physics is the holographic principle, which posits that the universe is actually a hologram. If researchers can prove the theory, it may lead to a grand unified theory that explains all the laws and principles governing reality.

Researchers in Denmark are finding that “forest bathing”, immersing children in natural spaces, has a beneficial effect for lowering risk of mental health disorders as adults.

The 4th National Climate Assessment details not only how climate change will impact our future, but the damage already inflicted on the environment and the economy, including disproportionately negative effects on disadvantaged communities.

Neuroscience studies on attention in both birds and humans reveal a remarkable natural rhythm in which a central focus is highlighted alternating with a wider view. In effect, the brain zooms in and zooms out several times a second. While this has benefits (including for survival in Jurassic Park), it also makes us vulnerable to distractions when the brain zooms out – another good reason to develop mindfulness.

The continental United States is 1.8 degrees Fahrenheit warmer than it was a century ago. Seas at the coasts are nine inches higher. Like a frog in a slowly heating pot, sometimes it’s hard to see the changes around us. This sobering article provides graphic evidence of how climate change is disrupting our lives.

The value of pets is well-known in helping people cope with loneliness and depression. One man has given this idea a new twist, with his “emotional support alligator.”

Many past estimates of the number of neurons in the human brain have been wildly inaccurate. The current findings are that we have about 80 billion neurons – and most of them are in the cerebellum, not the cerebral cortex. There are also another 80 billion non-neuronal “glial” cells. We keep most of these 160 billion cells over the entire lifespan: there’s hope!

You may have heard this before or something like it: “Neurons that fire together, wire together.” Have you ever wondered where it comes from? It is based on the pioneering work of the Canadian psychologist Donald Hebb in the middle of the 20th century, who explored how the brain can be changed by our experiences: the fundamental physical basis of learning, healing, and growth. Then in a research paper in 1992, Siegrid Lowel and Wolf Singer offered this summary –  “neurons wire together if they fire together” – which became the basis for this increasingly popular saying.

While getting enough sleep is important for our overall health and well-being, a new study shows that getting too much sleep can increase your risk to experience a cardiovascular disease or death.

Launched in 1977, Voyager 2 recently crossed the edge of the heliosphere—11 billion miles from Earth—and will provide the first-ever observations of interstellar space, using 40-year-old technology that has less data capacity than your smart phone.

The USA has the largest rate of incarceration of any OECD (Organization for Economic Cooperation and Development) country, over twice the rate of the second largest, Turkey, though the rate has steadily decreased since 2008.

Out past the orbit of Pluto, NASA’s New Horizons spacecraft has recently flown by Ultima Thule, a small planetoid. This object is the farthest from our planet that has been surveyed by a human device – so far away that it takes six hours for its radio signals traveling 186,000 miles a second to reach Earth.
