Six-fold rise in brain pressure disorder that affects mostly women
A brain pressure disorder that especially affects women, causing severe headaches and sometimes permanent sight loss, has risen six-fold in 15 years, and is linked to obesity and deprivation, a new study by Swansea University researchers has shown. Rates of emergency hospital admissions in Wales for people with the disorder were also five times higher […]
Bringing atoms to a standstill: Researchers miniaturize laser cooling
Illustration of a new optical system to miniaturize the laser cooling of atoms, a key step towards cooling atoms on a microchip. A beam of laser light is launched from a photonic integrated circuit (PIC), aided by an element called an extreme mode converter (EMC) that greatly expands the beam. The beam then strikes a […]
Earliest form of money found and it’s a bunch of rings and axes
Got change for an axe? Thousands of years ago, people used bronze objects such as neck rings, axe blades and “ribs” (curved, flattened rods) as a type of prehistoric currency, making them the oldest known form of money in the world.

Space station detectors spot the source of weird ‘blue jet’ lightning
Scientists have finally gotten a clear view of the spark that sets off an exotic type of lightning called a blue jet. Blue jets zip upward from thunderclouds into the stratosphere, reaching altitudes up to about 50 kilometers in less than a second. Whereas ordinary lightning excites a medley of gases in the lower atmosphere […]
Early humans used chopping tools to break animal bones and consume the bone marrow — ScienceDaily
Researchers from the Sonia and Marco Nadler Institute of Archaeology at Tel Aviv University unraveled the function of flint tools known as ‘chopping tools’, found at the prehistoric site of Revadim, east of Ashdod. Applying advanced research methods, they examined use-wear traces on 53 chopping tools, as well as organic residues found on some of […]

Over the years, recruitment has become more refined and evolved but there’s one trend that’s been around for a while: culture fit. A way of ensuring that new recruits will match the core attributes and values of the company, culture fit has widely been touted as an essential part of decision-making. However, the tide is […]
Overturning in the Pacific May Have Enabled a “Standstill” in Beringia
Planet Earth pulled out all the stops, it seems, to enable the first humans to reach North America. When a glacial period lowered sea levels and turned parts of the Bering Strait into a land bridge, a warm ocean current shielded that region from the worst cold, turning it into a refuge where […]
