A landmark discovery on an ancient branch of the River Nile may have solved the mystery of how the pyramids in Egypt were built centuries ago. The now dried-out waterway, which once ran through Giza might have been used to transport the materials that were used to construct the pyramids. The proximity to the waterway might also suggest why there is such a cluster of pyramids in that particular area of Cairo, as the large amount of water would have been able to support the various building blocks needed for the colossal structures. The discovery was made by Dr Eman Ghoneim who used radar satellite data from space to study the Nile Valley which showed an "invisible world of information beneath the surface." Ghoneim presented her research to the 13th Congress of Egyptologists earlier this year. Speaking to IFLScience Ghoneim said: "The length probably was really, really long, but also the width of this branch in some areas was huge. We're talking about half a kilometer or more in terms of width, which is something that is equivalent to today's Nile course width. So it wasn't a small branch. It was a major branch.” The defunct waterway has been dubbed the Ahramat Branch and ran from Giza to Faiyum and amazingly passed through 38 different pyramid sites. However, without confirmation of whether the river was active during the Old and Middle Kingdoms, around 4,700 years ago, cannot fully determine if water was used to help build the pyramids. One indication that it could have been used is that according to Ghoneim these pyramids were "located exactly at the bank of the branch that we found" which could mean that they were "valley temples" which acted like ancient ports. The research might not just unlock the secrets of the pyramids but it could also uncover parts of ancient Egypt that have long been lost as towns disappeared when the Nile naturally migrated. Ghoneim added: "As branches disappeared, Ancient Egyptian cities and towns also silted up and disappeared, and we have no clue actually where to find them."

Amazon.com Inc. has signed an agreement with rival SpaceX for three launches of Elon Musk’s Falcon 9 rocket,

A solar storm predicted to hit Earth on Friday (December 1) may cause internet blackouts, according to forecasters. Radio and GPS could also be affected due to the solar storm, also known as a coronal mass ejection (CME), which is caused by interference with Earth’s magnetic field. "A Direct Hit! The impressive #solarstorm launched in the Earth-strike zone has been modeledmodelled by NASA," space weather physicist Dr Skov posted on Twitter/X. "The storm is predicted to hit Earth by midday December 1. Along with two earlier storms already en route means we have a 1,2,3-punch. If the magnetic field is oriented correctly, expect #aurora to reach deep into mid-latitudes." She added: "Amateur #radio & #GPS reception issues are likely, especially on Earth's nightside. G3+ conditions are possible with this storm series." A solar storm can have substantial effects on the Earth, taking place when the sun emits powerful bursts of energy which come from solar flares and CME that contain charged plasma. During which, a stream of an electromagnetic field is directed towards Earth and this causes the aurora borealis. Three solar storms were predicted to advance towards Earth – and some may merge, resulting in increased disruptions to Earth’s magnetic field, according to The US National Oceanic and Atmospheric Administration (NOAA). “Along with two earlier storms already en route [this] means we have a 1,2,3-punch,” Dr Skov said. Consequently, she added there are “excellent chances” of strong G3-level magnetic storms and auroras on Earth. The way the strength of a solar storm is measured is with the letter G and then a number system from 1-5 (1 being the weakest, to 5 being the strongest). So a G3 level storm means radio, internet and GPS could be affected due to the strength of these events. Solar storms are also known to cause electrical grids and knock out satellites, depending on their strength. Meanwhile, experts have warned the solar storm thought to occur today may impact communication systems in high latitudes. “With 3 CMEs already inbound, the addition of a 4th, full halo CME has prompted SWPC forecasters to upgrade the G2 Watch on 01 Dec to a G3 Watch. This faster-moving halo CME is progged to merge with 2 of the 3 upstream CMEs, all arriving at Earth on 01 Dec,” the NOAA said. “G3 (strong) conditions are now likely on 01 Dec,” it added.

Fire might seem like one of the most elemental things in the natural world, but it’s never been found anywhere other than Earth. It’s because the creation of fire relies on very specific circumstances. In fact, if fire was ever found on another planet, it would be a good indicator of the possible existence of life. Oxygen is key to fire, and while it’s particularly prevalent in the universe, Earth’s atmosphere features an abundance of the element in the right molecular form for it to form. Even then, the way the Earth’s atmosphere has changed over its lifespan is also crucial to conditions being fostered where fire can form [via IFLScience]. For millions of years, in fact, there wasn’t enough oxygen in the atmosphere to create fire. Before the Middle Ordovician period, when there was far less oxygen, there’s no evidence of fire whatsoever. Most of the fuel that fire needs is also directly related to life existing on the planet – think wood, oil and coal. Without life, there isn’t an awful lot of fuel going around, which just shows why the existence of fire on another planet would be a very promising sign when it comes to exploring the universe for life. Despite fire being much rarer in the universe than most might think, it was previously confirmed that humans in Europe may have mastered fire long before we previously thought. According to a study published in Scientific Reports, humans made the discovery around 245,000 years ago, up to 50,000 years earlier than scientists believed, Researchers studied samples from the Valdocarros II, a huge archaeological site found east of Madrid, Spain. Using chemical analysis, they found certain compounds that show things were burnt by fire in "organised" social events, rather than through accidents or wildfires.

A study last year found that every time you throw away a banana peel, you're missing out on a great snack. The study, published in ACS Food Science & Technology, found that if banana peels are blanched, dried, and ground into a flour, they can be turned into baked goods that taste just as good as wheat-based products. And it turns out it's actually really food for you. Consuming products made from banana peel means you consume minerals and cancer-fighting minerals. Sugar cookies that were enriched with banana peels not only tasted the same as peel-free sugar cookies, but contained much more fibre, magnesium, potassium, and antioxidant compounds. In 2021, a study on banana peel cake found the yellow skin of the fruit provided a natural food colour as well as a nutritional boost. Whilst a 2016 study found that substituting up to 10 per cent of wheat flower with banana peel flour can enrich baked bread with higher protein, carbohydrate, and fat contents. Not only is it a healthy food option, it also helps reduce food waste! And the same goes for other fruits too, such a mango skin, what was found to boost a cake's antioxidant properties and improve its flavour. Just make sure to add the right amount of banana peel to your bakes and makes. Adding too much banana peel flour did result in the study's cookies going somewhat brown and hard, possibly from all the extra fibre. 7.5 percent of banana peel flour seems to be the sweet spot, with the texture and taste hitting an appealing balance. So maybe reconsider next time you go to thrown a banana skin away. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Our canine companions could soon be enjoying much longer lifespans, if a drug which claims it can extend dogs’ lives eventually gets approved. The drug, made by a tech firm in California, just cleared a vital hurdle to doing just that, after it got partial approval by regulators in the US. Loyal, a San Francisco-based company founded in 2020, has been researching how it can increase dogs’ lifespans – in particular larger breeds, which tend to die younger. Large and “giant” breeds tend to live to between eight and 12 years. Smaller dogs, such as Chihuahuas, can keep going to the ripe old age of 20. Loyal’s main product, the catchily-titled LOY-001, is designed not only to extend dogs’ lives but also maintain their quality of life. Now, it has passed the “reasonable expectation of effectiveness” test, set by regulators at the US’ Food and Drug Administration. Loyal’s chief executive, Celine Halioua, said: "Loyal was founded with the ambitious goal of developing the first drugs to extend healthy lifespan in dogs. "This milestone is the result of years of careful work by the team. We'll continue to work just as diligently to bring this and our other longevity programs through to FDA approval." Selective breeding of dogs has caused higher levels of hormones which help the animals grow faster. That is also believed to reduce their lifespan, the company said. Big dogs tend to have more of this hormone than their smaller counterparts. Animal rights activists are not yet convinced. Some experts fear it will only serve to extend animals’ suffering. Loyal, on the other hand, says the drug aims to treat doggy diseases which are associated with ageing through preventing them, rather than waiting for the animals to get sick before treating them. The company said that the drug could be available to US customers as early as 2026. So that’s plenty of time for walkies between now and then.
