Cheetahs may hold the reputation for being the world’s fastest animal – and with a running speed of up to 120 kilometers per hour (75 miles per hour), the feline is indeed the quickest animal on land. But that pales in comparison to the impressive diving speeds of the peregrine falcon, which, according to the […]

Parker Solar Probe has survived achieving the record-breaking closest pass to the Sun by a human-made spacecraft ever – and phoned home even earlier than expected, confirming it survived “touching the Sun” and reaching the pinnacle of its mission. The already record-breaking probe – the fastest human-made object in the cosmos – carried out its […]

Archaeologists have revealed evidence of a never-before-seen sacrifice of family members belonging to the ancient Andean Moche culture, revealing new insights into their social world, customs, burial practices, and the role of kinship. The Moche culture – who lived along Peru’s North Coast between 300 and 950 CE – is known to have created sophisticated […]

A duo of researchers at Caltech have attempted to quantify the speed of human thought, putting it at a somewhat perplexing 10 bits of information per second. To put that into perspective, one estimate of the slowest average download speed in the USA in 2024 clocked in at 93 megabits per second (Mbps), though the […]

The magnetic field – or magnetosphere – is a giant invisible shield that protects the planet, repelling solar wind and other forms of space weather that could threaten life on Earth. It is essential for the running of our global navigation systems (and those of ants, sharks and other animals), not to mention our ability […]

Though you might think that compasses will always point towards the geographic north pole, the magnetic and geographic poles do not always align. As well as a few temporary reversals, the Earth’s magnetic field – just like the Sun – can flip over long timescales. During the Brunhes–Matuyama reversal, the magnetic north could have been […]

The shortest distance between any two points is a perfectly straight line, and given the brilliant efficiency of the natural universe, it figures that linear flawlessness must be a feature of our reality. Look closely enough, however, and you’ll find that things aren’t that simple, as we are in fact surrounded by glorious imperfection. Of […]

Lucy, our 3.2 million-year-old ancestor of the species Australopithecus afarensis, may not have won gold in the Olympics – but new evidence suggests she was able to run upright. According to digital simulations developed by researchers in the UK and the Netherlands, Lucy would have been able to reach top speeds of 4.97 meters per […]

In 2018, Tahlequah the killer whale made headlines and broke hearts after she was spotted carrying the body of her dead calf for 17 days. This month, sightings of the orca show she has recently given birth again . According to a Facebook post by the Center for Whale Research (CWR), the new calf has […]

Researchers have developed a new groundbreaking technology that can convert some cancer cells into a state that resembles normal cells without killing them. This approach not only represents a new way to potentially treat cancer, but also one that avoids side effects produced by other treatments and the risk of resistance. Cancer reversion, which regresses […]

A team studying the group behavior of ants has found that, in the right circumstances, ants can outsmart humans in collective problem-solving tasks. Researchers from the Weizmann Institute of Science wanted to take a closer look at “collective cognition”, and whether groups can sometimes tackle problems with more ease than when performing the tasks individually, […]

Life has limits that mean that not everything we can imagine is possible, a multidisciplinary team of scientists has argued. The capacity to rule out some forms of life, based on scientific laws, allows us to focus our energies both when it comes to searching for life on other worlds and making it in laboratories. […]

The Pyramids of Euseigne are far, far older than the Pyramids of Giza – although, perhaps comparisons are a little unfair since they were crafted by natural forces, not human ingenuity. They are found in an alpine valley called Val d’Hérens in the Swiss Alps, not far from the village of Euseigne.  Back in 1983, […]

A particular view of the Canyon de Chelly National Monument will soon become off-limits to tourists, after a decision to prohibit commercial air tours of the area, believed to be one of the longest, continuously-inhabited areas in North America. The National Park Service (NPS) and the Federal Aviation Administration (FAA) announced on Friday, December 20 […]

The first patient in the UK has successfully received a double-lung transplant using a machine that is being nicknamed “lungs in a box”. The XPSTM system from XVIVO could improve the number of available lungs for donation, helping those currently waiting for the life-saving procedure.  The patient, 49-year-old Daniel Evans-Smith, underwent this procedure at the Royal […]

For as long as humans have set eyes on Earth, we’ve been besotted with red – the color of blood, lust, luck, pain, and passion. It’s the first primary color we’re able to see as babies and the early introduction leaves a lasting impression on us. Forget soothing blues and luscious greens, it’s red that […]

Using nothing but sunlight and photocatalysts, a 100 square meter (1,076 square foot) reactor produced carbon-free hydrogen for three years, demonstrating the potential of the concept. The approach is still considerably less efficient than the more common method, where photovoltaic panels turn the sunlight to electricity first, but in theory the direct approach could bring […]
