That same team has now uncovered nearly 500 smaller ceremonial complexes that are similar in shape and features to Aguada Fénix. The find transforms previous understanding of Mesoamerican civilization origins and the relationship between
Most elements lighter than iron are forged in the cores of stars. A star's white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond iron, scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe's heavy elements, whose formation requires more energy than a star can muster.
The sharpest images ever of living bacteria have been recorded by UCL researchers, revealing the complex architecture of the protective layer that surrounds many bacteria and makes them harder to be killed by antibiotics.
Protein intake is known to be vital for maintaining brain function in older individuals. Now, using a mouse model of Alzheimer's disease, researchers have shown that the intake of a specific set of amino acids can inhibit the death of brain cells, protect the connections between them, and reduce inflammation, preserving brain function. Their research suggests that this amino acid combination calle

But the island's tropical forests hide a diversity of tiny insects that still remains largely unexplored. Museum scientists from Indonesia and Germany have just discovered 28 new species of beetles, all belonging to the weevil genus Trigonopterus.
Plants are not entirely at the mercy of their herbivore enemies. Often, chemical defenses ensure that the plants are inedible, or even toxic, and as a result insects and other hungry animals steer clear of them. A new study has shown, for the first time, that the degradation of plants' defense substances by insects' digestive enzymes can influence the insects' preference for certain food plants. R
