Children who lack sleep may experience detrimental impact on brain and cognitive development that persists over time.

Research finds getting less than nine hours of sleep nightly associated with cognitive difficulties, mental problems, and less gray matter in certain brain regions

Chinese booster rocket makes uncontrolled return to Earth

Objects generate immense amounts of heat and friction when they enter the atmosphere, which can cause them to burn up and disintegrate. But larger ones such as the Long March-5B may not be destroyed entirely.

In 2020, debris from another Chinese rocket fell on villages in the Ivory Coast, causing structural damage but no injuries or deaths.

Pinpointing consciousness in animal brains using a mouse 'brain map'

Science may be one step closer to understanding where consciousness resides in the brain. A new study shows the importance of certain types of neural connections in identifying consciousness.

"Where in the brain consciousness resides has been one of the biggest questions in science," said Associate Professor Masafumi Oizumi, corresponding author and head of the lab conducting the study. "Although we have not reached a conclusive answer, much empirical evidence has been accumulated in the course of searching for the minimal mechanisms sufficient for conscious experience, or the neural correlates of consciousness."

We Must Start Preparing Now For How Climate Change Might End Civilization, Says Report

Speculating over humanity's demise is a sport we humans have enjoyed since forever. We build religions on our eschatological hopes, weave fiction out of our dystopian fears, and even write songs about the end of the world as we know it.

So it's surprising that in the midst of an escalating global climate crisis, one that impacts everything from the health of individuals to the sustainability of entire ecosystems and their resources, potential global catastrophes are so underexplored.

A report published recently in the Proceedings of the National Academy of Sciences argues it's high time we start taking worst-case scenarios seriously and come up with a solid game plan on what happens if – or indeed, when – our current way of life collapses.

Cartwheel Galaxy (NIRCam and MIRI Composite Image)

This image of the Cartwheel and its companion galaxies is a composite from Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), which reveals details that are difficult to see in the individual images alone.

This galaxy formed as the result of a high-speed collision that occurred about 400 million years ago. The Cartwheel is composed of two rings, a bright inner ring and a colorful outer ring. Both rings expand outward from the center of the collision like shockwaves.

⁣⁣Solar storm will hit Earth Today (Aug. 3)

High-speed solar winds from a "hole" in the sun's atmosphere are set to hit Earth's magnetic field Today (Aug 3.), triggering a minor G-1 geomagnetic storm.

As a G1 geomagnetic storm, it has the potential to cause minor fluctuations in power grids and impact some satellite functions — including those for mobile devices and GPS systems. It will also bring the aurora as far south as Michigan and Maine in the US.

45 years ago, Voyager 2 (shown in the background) launched at 10:29 a.m., carrying this Golden Record and flag on its quest into deep space.

Voyager 2 is the only spacecraft to have visited Uranus and Neptune, and along with Voyager 1, is NASA's longest-lived mission!

Is Civilization on the Brink of Collapse?

At its height, the Roman Empire was home to about 30 % of the world’s population, and in many ways the pinnacle of human advancement. Rome became the first city in history to reach one million inhabitants and was a center of technological, legal, and economic progress. An empire impossible to topple, stable and rich and powerful.

Until it wasn’t anymore. First slowly then suddenly, the most powerful civilization on earth collapsed. If this is how it has been over the ages, what about us today? Will we lose our industrial technology, and with that our greatest achievements, from one dollar pizza to smartphones or laser eye surgery? Will all this go away too?

The sounds of a black hole

The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound.

Here it's amplified, and mixed with other data, to hear a black hole!
