Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonized economy.

New research highlights the risks of countries relying on nature-based solutions to achieve net-zero. National climate strategies set out how countries plan to reduce emissions, for example by phasing out fossil-fuel use, to get to net-zero in 2050. The study found, once the bulk of emissions have been reduced, countries plan to 'cancel out' the left-over difficult to decarbonise emissions, such as those from agriculture, by using forests and soils to remove carbon from the atmosphere.

Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids -- life's building blocks -- to our planet. Now, researchers have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the space rocks.

Researchers have demonstrated a new way to create stable perovskite solar cells, with fewer defects and the potential to finally rival silicon's durability.

Scientists have solved a decades-long mystery as to why ancient tetrapods -- amphibian-like creatures that lived over 300 million years ago -- preserved in one of Ireland's most important fossil sites seemingly had their bones cooked after they died.

A new, low-cost staining method enables visual tracking of coral larvae as they disperse and settle in coral reefs, according to a study.

Efforts to conserve rhinos in Nepal have put a burden on communities, infrastructure and other wildlife in Nepal, a new study warns.

Scientists have found new evidence for how armored dinosaurs used their iconic tail clubs. The exceptional fossil of the ankylosaur Zuul crurivastator has spikes along its flanks that were broken and re-healed while the dinosaur was alive -- injuries that the scientists think were caused from a strike by another Zuul's massive tail club. This suggests ankylosaurs had complex behavior, possibly battling for social and territorial dominance or even engaging in a 'rutting' season for mates.

New research, based on two decades' worth of data, shows that in the ten years after its onset in 2000, the Southwestern North American (SWNA) megadrought caused a 30% change in gravity wave activity in Earth's upper atmosphere.

For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.

A chance find of an unstudied Antarctic sediment core has led researchers to flip our understanding of how often ice ages occurred in Antarctica.

Researchers have simulated how climate change will affect the distribution of two leading allergens -- oak and ragweed pollens -- across the contiguous United States. The results may make your eyes water. Using computer models, the team found that by 2050 climate change significantly will increase airborne pollen loads, with some of the largest surges occurring in areas where pollen is historically uncommon.

Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the distant, early universe. Only 1,200 light-years across, the tiny galaxy HIPASS J1131-31 has been nicknamed "Peekaboo" because of its emergence in the past 50-100 years from behind the fast-moving star that was obscuring astronomers' ability to detect it.

Researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.

The El Niño phenomenon influences the weather in distant regions, as far away as the USA, India or the Mediterranean region. But how exactly these so-called teleconnections actually work has not yet been clarified completely. Atmospheric researchers at have now succeeded in demonstrating that variations of the transport of air mass, heat, moisture and energy from the tropical Pacific are responsible for many of these climate anomalies. And: El Niño also warms up the Atlantic.

Researchers have discovered a new method to move objects using ultrasound waves, opening the door for using contactless manipulation in industries such as robotics and manufacturing.

An almost limitless supply of fresh water exists in the form of water vapor above Earth's oceans, yet remains untapped, researchers said. A new study suggests an investment in new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.

Experimental physicists growing icicles are closer to understanding why some form with ripples up and down their outsides, while others form with smooth, slick, even surfaces. By growing icicles from water samples with different contaminants like sodium chloride (salt), dextrose (sugar) and fluorescent dye, they discovered that water impurities become entrapped within icicles as they form and subsequently create chevron patterns that contribute to a ripple effect around their circumferences.

Researchers report the synthesis of semiconductor 'giant' core-shell quantum dots with record-breaking emissive lifetimes. In addition, the lifetimes can be tuned by making a simple alteration to the material's internal structure.

A forest's resilience, or ability to absorb environmental disturbances, has long been thought to be a boost for its odds of survival against the looming threat of climate change. But a new study suggests that for some Western U.S. forests, it's quite the opposite. The results of one of the first large-scale studies of its kind show that while high ecosystem resilience correlates with low mortality in eastern forests, it is linked to high mortality in western regions.
