A new technique analysing modern genetic data suggests that pre-humans survived in a group of only 1,280 individuals.
Unearthing of fossilized remains in Turkey suggests human origins may actually lie in Europe Africa has always been considered the cradle of mankind, with humans evolving from apes on the continent, before spreading to the rest of the world. But an intriguing find is challenging the long-standing assumption.

Human waste doesn’t need to be wasted, thanks to some University of Florida researchers. They’re working on a way to power rockets with poop. The technique could be used to cut mission costs for future return missions from the Moon—since astronauts will be making some of the fuel once they arrive.
Robots for good 👍.

Apple may not be as flashy as other companies in adopting artificial intelligence features. Still, the already has a lot of smarts scattered throughout iOS.
Apple does not go out of its way to specifically name-drop “artificial intelligence” or AI meaningfully, but the company isn’t avoiding the technology. Machine learning has become Apple’s catch-all for its AI initiatives.
Apple uses artificial intelligence and machine learning in iOS in several noticeable ways. Here is a quick breakdown of where you’ll find it.
An international team of scientists has found a crucial link between the chemistry of Earth’s deep mantle and its early atmosphere. The study uncovers new insights into the evolution of life on our planet and the surge of atmospheric oxygen.
The scientists focused their investigation on magmas formed in ancient subduction zones, areas where portions of Earth’s crust sink back into the mantle.
The experts examined a critical juncture in Earth’s history known as the Great Oxidation Event (GOE), which occurred between 2.1 and 2.4 billion years ago.
Bottom-up processing is an explanation for perceptions that start with an incoming stimulus and work upward until a representation of the object is formed in our minds. This process suggests that our perceptual experience is based entirely on the sensory stimuli that we piece together using only data that is available from our senses.
In order to make sense of the world, we must take in energy from the environment and convert it to neural signals, a process known as sensation. It is in the next step of the process, known as perception, that our brains interpret these sensory signals.
How exactly do people process perceptual information from the world around them? There are two basic approaches to understanding how this sensation and perception take place. One of these is known as bottom-up processing and the other is known as top-down processing.
