Botswana is humanity’s ancestral home, claims major study – well, actually …

Image
A recent paper in the prestigious journal Nature claims to show that modern humans originated about 200,000 years ago in the region around northern Botswana . For a scientist like myself who studies human origins, this is exciting news. If correct, this paper would suggest that we finally know where our species comes from. But there are actually several reasons why I and some of my colleagues are not entirely convinced. In fact, there’s good reason to believe that our species doesn’t even have a single origin. The scientists behind the new research studied genetic data from many individuals from the KhoeSan peoples of southern Africa, who are thought to live where their ancestors have lived for hundreds of thousands of years. The researchers used their new data together with existing information about people all around the world (including other areas traditionally associated with the origins of humankind) to reconstruct in detail the branching of the human family tree. We can thi

Wiko View 3 Pro camera review

The View 3 Pro is a lower mid-range smartphone from value-focused French manufacturer Wiko. It features a 6.3-inch IPS display with FHD+ resolution and a Mediatek Helio P60 chipset. Its 128Gb of internal storage can be expanded via an SD card slot. On the imaging side of things, the device offers a triple-camera setup that includes a 12Mp wide-angle with a 27mm-equivalent focal length lens, and a 13Mp ultra-wide-angle lens that has a 16mm-equivalent field of view . The third camera is a depth sensor that is predominantly used to create the bokeh simulation in portrait mode. Wiko is a brand name that is not familiar to everyone; let’s see how the View 3 Pro fared in our DXOMARK Camera testing.

Victorian scientists thought they’d found an explanation for ghosts – but the public didn’t want to hear it

Image
As the film Ghostbusters showed, true believers in the supernatural rarely prosper in the scientific establishment. Throughout history, scientists who entertained theories on ghosts, magic and the afterlife were discredited by their peers and condemned for tarnishing the rational foundations of the discipline. Even Isaac Newton carefully downplayed his interest in alchemy to preserve his reputation as the father of modern science. Victorian Britain experienced the golden age of the literary ghost story – when imaginations ran wild at the very thought of the supernatural. But at the same time, there seemed no dark corner that a rational, scientific mind couldn’t illuminate. Researchers such as John Ferriar and Samuel Hibbert were keen to clear up all the talk of phantoms. With their scientific remedy to hauntings and apparitions, the Ghostbusters may have found a favourable audience in Victorian Britain.

Announced in May 2019, the Honor 20 Pro is the latest top-end device from Huawei’s budget-friendly sub-brand. The phone’s specifications are impressive, featuring a 6.26-inch LCD, a high-end Kirin 980 chipset, and 8Gb of RAM. Its quad-cam setup performed admirably in our rear camera tests—ahead of some of the more expensive flagship competitors. Its front camera features a high- resolution 32MP sensor coupled to an f/2 lens for stills, and 1080p video with gyroscope-enabled Electronic Stabilization ( EIS ). Read on to see if the Honor 20 Pro can also punch above its weight in our DXOMARK Selfie tests.
