Relentless rains in Pakistan over two months have caused the country’s worst flooding in more than a decade. Floodwaters have washed away roads, buildings, and crops. A third of the country, an area about the size of Colorado, is now underwater, according to the country’s climate minister. Officials estimate that more than 33 million Pakistanis

Seeing the famed pyramids of Giza as they stand today – immovable, impenetrable fortresses surrounded by windswept sands and a sprawling metropolis – it’s hard to imagine the day they were built. These stone labyrinths, constructed to honor the dead and carry them into the afterlife, were erected around 4,500 years ago without modern technology

Although we’re more connected than ever, hatred and bigotry towards social groups seen as ‘Other’ remain rife in our world. To maintain a positive self-image, individuals may claim false positive beliefs toward such people. But new research reveals that patterns in their language can betray this dishonesty. “People lie for a reason, especially when the

There are two theories about where teeth originated: They either evolved from external scales (the outside-in hypothesis) or from somewhere inside the mouth (the inside-out hypothesis). Researchers studying a fossil of the Ischyrhiza mira species – an extinct sawfish that lived in North America around 65 to 100 million years ago – have found more

Scientists have developed an ‘atomic television’ that uses lasers and atom clouds to carry a video signal that meets the traditional 480i resolution (480 horizontal lines) standard. Just don’t expect it to be installed as part of your home entertainment setup any time soon. Key to the technology is a glass container of gaseous super-sized

The world is heating up, and it’s threatening habitability in many regions around the equator. At this stage, even if we can limit global warming to 2 ˚C above pre-industrial levels, new estimates suggest the tropics and subtropics, including India, the Arabian peninsula and sub-Saharan Africa, will experience dangerously hot temperatures most days of the

Massive swathes of wilderness and the lives of billions of animals were extinguished into ash and smoke during Australia’s Black Summer bushfires. The resulting haze suffocated major cities, triggered fatal health emergencies, and turned distant glaciers brown. Now researchers have directly traced how some of this burnt biomass contributed to the largest stratospheric warming in

The first hormonal contraceptive (the ‘pill’) was approved by the US Food and Drug Administration in 1960. Hormonal contraceptives have since become one of the most prescribed drugs in the world, used daily by more than 100 million people worldwide. These drugs prevent pregnancy by delivering synthetic hormones into the bloodstream. Synthetic hormones stop the

This new image, taken of the skies above Chile’s Atacama Desert near the European Southern Observatory’s (ESO) La Silla Observatory, shows bright red streaks in the sky known as red sprites. Red sprites are large-scale electrical discharges that occur high above thunderstorm clouds, usually triggered by the discharges of positive lightning between an underlying thundercloud

The notorious weed-killer, Roundup, originally made by Monsanto and acquired by Bayer, has been found to cause seizure-like convulsions in roundworms. When a soil-dwelling species, Caenorhabditis elegans, was exposed to highly diluted samples of Roundup – 300 times lower than the lowest concentration recommended for consumer use – researchers found the herbicide elicited prolonged paroxysms.

The dazzling beauty of a snowflake is testament to the amazing shapes water can form below freezing point. Placed under pressure, the elegant dance of the H2O molecule contorts into something bizarre at super chilly temperatures, virtually tying themselves in knots to avoid transforming into ice. Researchers from the University of Birmingham in the UK

When a comic about “mental load” went viral in 2017, it sparked conversations about the invisible workload women carry. Even when women are in paid employment, they remember their mother-in-law’s birthday, know what’s in the pantry and organize the plumber. This mental load often goes unnoticed. Women also continue to do more housework and childcare

Just because an artificial sweetener has zero or very few calories doesn’t mean there are zero (or very few) health consequences to consuming the sachet. A randomized controlled trial recently found that regular consumption of sucralose (marketed as Splenda) and saccharin (marketed as Sweet’N Low) can alter microbes in the gut and elevate the body’s
