Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and operation. For instance, the nucleus stores genetic material, and mitochondria produce energy. Another essential part of a cell is the membrane that encloses it. Proteins embedded on […]

El Niño and La Niña May Have Affected Weather For At Least 250 Million Years
New modeling research has shown that the natural global climate phenomena known as El Niño and its cold counterpart, La Niña, have been occurring for the last 250 million years. Although these complex weather patterns are the drivers of extreme weather changes today, the research suggests they were significantly stronger in the past. El Niño […]
What Is The Oldest Continuously Inhabited City In The World?
At some point in human history, our ancestors decided to urbanize, building sprawling metropolises to live and work in. Some of these ancient cultural and economic hubs are still standing today, and have been inhabited ever since their construction – but which is the oldest? It’s not an easy question to answer – these cities […]
16-Million-Year-Old Sawfly Fossil Is First-Of-Its-Kind Ever Discovered
Researchers have discovered a brand new species of sawfly from an amazingly preserved fossil found in Australia. This is a great discovery – but we need to remember that sawflies are not flies at all. The new species is long extinct but would have been flying around what is now Australia in the Miocene Period. […]
Should Daylight Saving Time Be Abolished?
Daylight saving time (DST) has been around in the US on and off since 1918, but after 106 years’ worth of back and forth – both in terms of political decision-making and, y’know, clocks – is it time to ditch it for good? What is daylight saving time – and why do we have it? […]
Easter Island Reveals Odd Insights Into Earth’s Tectonic Plates And Mantle
Extinct volcanoes that lurk around Rapa Nui, aka Easter Island, may challenge some parts of the standard explanation about how tectonic plates move around our planet. It’s often taught that Earth’s rocky tectonic plates sit on top of a syrup-like bed of viscous rock, known as the mantle, that moves along with those plates like […]
Iron-60 Is Not Of This World, So Where Is It From?
There are a small number of isotopes that offer clues regarding ancient supernovae that helped shape the Earth and the rest of the Solar System. Of these, the one astronomers and planetary scientists turn to most often is iron-60, so what makes it so useful? Most of the elements that make up the Earth are […]
Proposed Spacecraft To Chase Moon’s Shadow To See One Eclipse Per Lunar Month
Total solar eclipses like the one that crossed North America this year are not just incredibly beautiful spectacles, they are scientifically valuable too. They allow us to study the solar corona (the outermost part of the Sun’s atmosphere) in important ways. However, due to the alignments of the Sun, Earth, and Moon, despite being regular, […]
The Smell Of Death Has A Strange Influence On Human Behavior
Did you know that flies can smell a body from miles away and even dig down as far as 2 meters (6.5 feet) to wriggle into a coffin and lay their eggs? They’re lured in by chemical signals, but it seems it’s not just scavengers that can detect the smell of death. Research has uncovered […]
Revolutionary Nasal Nerve Cell “Bridges” For Treating Spinal Injuries To Begin Clinical Trials
Clinical trials are about to begin for a spinal injury treatment using a “bridge” – made of stem cells from the patients’ own noses – over the damage. Millions of people worldwide have spinal injuries, creating immense demand for cures, so research indicating a path to treating spinal injuries using stem cells from the nose […]
Lonely Quasars Seen By JWST Challenge Expected Formation Theory
Quasars occur when supermassive black holes gobble up an incredible amount of gas. Observations and general wisdom suggested that a galaxy needed a lot of neighbors to deliver that much gas to a supermassive black hole at its center – so imagine the surprise of seeing not one but five quasars on their own. Looking […]
Why Do We Bury People In Coffins And Not Just In The Ground?
Human burial has been practiced for millennia as a way of dealing with our dead, but it’s not a perfect solution. America is estimated to contain around 404,685 hectares (1 million acres) of land currently dedicated to human burial, and the production of caskets sees around 1.6 million hectares (4 million acres) of forest lost […]
China’s Record-Breaking Resistive Magnet Produces Field Over 800,000 Times Stronger Than Earth’s
China has broken a record by creating the world’s most powerful resistive magnet, just surpassing the previous record set by the US. The new magnet is capable of creating a magnetic field of 42.02 tesla, which is more than 800,000 times stronger than the Earth’s and beats the 41.4 tesla record set by the US […]
IFLScience We Have Questions: What’s It Like Working In A Human Tissue Bank?
Sometimes surgeons need to remove parts of our bodies to make them healthy, but where do those sections of human go? They can be destroyed, but other times – with the patient’s consent – they are handed over to scientists to see what we can learn from diseased tissues. Those scientists work in what we […]
Why Do Some American States Have Panhandles?
So, we’ve seen panhandles that were created through compromise, through skullduggery, and through that age-old motivator, vendettas against Spain. But not all the states’ irregular shapes have such innocent origins – and in fact, like so much of US history, a lot of it is downright bloody. Step up to the plate, Oklahoma and West […]
As The Sun Officially Hits Solar Maximum, We Are Studying Our Star Like Never Before
NASA, NOAA, and the International Solar Cycle Prediction Panel have confirmed the Sun has reached solar maximum, slightly earlier than expected in its 11-year cycle. Thanks to the solar probes, telescopes, and missions currently studying our star, this is not the solar maximum of 2014, we can now study it in detail in ways never […]
Why Does The USA Still Have An Electoral College?
In just a few short weeks, Americans will head to the polls and elect their next President. Right? Wrong. It’s perfectly possible that whichever candidate gets the most votes might actually lose the election this year – it’s exactly what happened in 2016, and 2000, and 1888 before that.

Diamond Dust Could Help Cool The Planet And Avoid Catastrophe
Could diamond dust help solve climate change? The precious rock might not be the first thing to cross your mind when you think of climate change but researchers have come up with an innovative way to reverse global warming, at least in theory. The plan would involve ejecting 5 million tons of diamond particles into […]
Mysterious Origins Of Uruguay’s World-Famous Amethyst Deposits Uncovered
Northern Uruguay is home to one of the largest amethyst deposits in the world – but their formation has long been a mystery. Using cutting-edge techniques, researchers are unraveling their origin story and have discovered that these stunning gems crystalized at surprisingly low temperatures. Amethysts are a type of quartz, recognizable by their striking violet […]
The Sun Has Reached Solar Maximum, Microplastics Detected in Wild Dolphin Breath, And Much More This Week
This week, the most complete thylacine genome yet has been reconstructed in a push for de-extinction, high-THC cannabis leaves a unique signature on users’ DNA, and gravity may be to blame for Neanderthals never adopting advanced spear-throwing technology. Finally, here’s what to know about the common eye condition, astigmatism. Subscribe to the IFLScience newsletter for […]
