Rechargeable lithium-ion batteries are basically everywhere, powering everything from smartphones to notebooks, earbuds to gaming devices, and so much more. But while the convenience of this ubiquitous (and Nobel Prize-winning) battery chemistry has radically changed the way we use and charge portable technology, lithium-ion is far from perfect. The performance of lithium-ion batteries degrades over

Archaeologists have found a “Lost Golden City” that’s been buried under the ancient Egyptian capital of Luxor for the past 3,000 years, the Egyptian Ministry of Tourism and Antiquities announced Thursday (April 8).  The city, historically known as “The Rise of Aten,” was founded by Amenhotep III (ruled 1391-1353 BCE), the grandfather of Tutankhamun, or King Tut.

A bacterium that dwells deep underground, living off chemical reactions triggered by radioactive decay, has been doing so unchanged for millions of years, new research has found. A genetic analysis of microbes of the species Candidatus Desulforudis audaxviator (CDA) collected from three different continents has revealed that the bacterium has barely evolved since they were last

Earth’s transition to permanently hosting an oxygenated atmosphere was a halting process that took 100 million years longer than previously believed, according to a new study. When Earth first formed 4.5 billion years ago, the atmosphere contained almost no oxygen. But 2.43 billion years ago, something happened: Oxygen levels started rising, then falling, accompanied by massive

Even after a year of coronavirus lockdowns and shutdowns, global emissions of greenhouse gases are still increasing at an unrelenting rate.  Today, according to initial measurements from the National Oceanic and Atmospheric Administration (NOAA), global levels of carbon dioxide emissions are higher than they have been at any given time in the past 3.6 million years.

The results from one of the most hotly-anticipated experiments in particle physics are in, and they could be about to fulfill every researcher’s wildest dreams: They maybe, perhaps, could break physics as we know it. Evidence taken from the Fermi National Accelerator Laboratory near Chicago appears to point to a minuscule subatomic particle known as the muon wobbling far

Trekking out to my research sites near North Carolina’s Alligator River National Wildlife Refuge, I slog through knee-deep water on a section of trail that is completely submerged. Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in the water are small and stunted. Many are

While some blue-green algae (or more accurately – cyanobacteria) are critical to us for their nitrogen-fixing abilities, others can also become dangerous pests of our own making. Climate change and agricultural run-off are causing a once normal environmental process to spiral out of control more often, and a new study has shown that a particularly dangerous toxin produced

NASA’s InSight lander felt the distant rumble of two major ‘marsquakes’ in March, originating from a region near the Martian equator known as the Cerberus Fossae. Registering magnitudes of 3.1 and 3.3 on March 7 and March 18 respectively, the quakes cement the Cerberus Fossae’s reputation as one of the most geologically active places on

The mesmerizing red algal species Phymatolithon calcareum clumps together to form habitats called maerl beds in coastal regions across the northeast Atlantic, but researchers have discovered a pocket of the algae near Cornwall in the UK that’s genetically distinct from the rest of the region. It’s been dubbed ‘falgae‘, likely because of its location in the

NASA’s Ingenuity mini-helicopter has been dropped on the surface of Mars in preparation for its first flight, the US space agency said. The ultra-light aircraft had been fixed to the belly of the Perseverance rover, which touched down on the Red Planet on February 18. “MarsHelicopter touchdown confirmed!” NASA’s Jet Propulsion Laboratory tweeted Saturday. “Its

It is no exaggeration to say that the study of extrasolar planets has exploded in recent decades. To date, 4,375 exoplanets have been confirmed in 3,247 systems, with another 5,856 candidates awaiting confirmation. In recent years, exoplanet studies have started to transition from the process of discovery to one of characterization. This process is expected to accelerate

Nobody ever said parenting was easy, but depending on circumstances, some people can find it much harder than others. In recent years researchers have begun to recognize ‘parental burnout‘ – a condition in which exhausted parents become overwhelmed by their role as primary carers, potentially leading to emotional distance from their children, parental ineffectiveness, neglect,
