Dinosaurs, unlike humans, had no umbilical cord because they deposited eggs. Dinosaur yolk sacs were connected to the body by a slit-like aperture, also discovered in other egg-laying terrestrial animals. This is the opening that is sealed up about when the animal hatches, leaving a long umbilical scar. While the egg-laying nature of dinosaurs predicts
By developing a new versatile and robust electrolyte, the University of California San Diego engineers have developed lithium-ion batteries that perform well at freezing cold and scorching hot temperatures. Such batteries could be used in electric vehicles in cold climates to travel farther on a single charge. They might also lessen the requirement for cooling
Rebuilding of marine ecosystems after the devastation at the end of the Permian invited multiple lineages of reptiles to the marine habitat, leading to the well-known explosive radiation of marine reptiles in the Early Triassic and early Middle Triassic. Two major lineages of marine reptiles, the ichthyosaurs, and the sauropterygians, were part of this explosive
Accurate spatial models of tectonic plates and geological terranes are essential for analyzing and interpreting a wide variety of geoscientific data and developing compositional and physical models of the lithosphere. In a new study, scientists at the Universities of Adelaide, Tasmania, Nevada-Reno, and Geoscience Australia, created new models for tectonic plates that offer fresh insights
Single photons are ideal carriers of quantum information, especially because they are fast, they barely interact with the environment or each other, and large-scale infrastructure for their distribution is already widely available. Now, before networks can really turn quantum, suitable quantum memories for single photons are needed. It is required for everything from buffering communication
The Earth is warming from human activities, primarily because of increased carbon dioxide and other greenhouse gases in the atmosphere. This creates an energy imbalance at the top of the atmosphere called Earth’s energy imbalance. A new study- published today in the first issue of Environmental Research: Climate, a new open-access journal- suggests that knowing
Natural gas, consisting mainly of methane, has a relatively low energy density under ambient conditions. Partial oxidation of methane to methanol lifts the energy density and drives the production of numerous chemicals. An international team of researchers, led by scientists at the University of Manchester, has developed a fast and economical method of converting methane
A giant asteroid’s impact is considered the likely cause of the mass extinction of the dinosaurs almost 66 million years ago. While there is no potential harm from an asteroid on the Earth at present, it is still important to keep our defense system ready in order to prevent catastrophic consequences such as impacts by
The neutron’s lifetime is a significant parameter in Standard Model because it is used as an input for calculating the quark mixing matrix, which describes quark decay rates. If the quarks don’t mix as we expect them to, that hints at new physics beyond the Standard Model. To solve a long-standing puzzle about how long
Growing global food demand is currently facing a major constraint of efficient energy conversion using photosynthesis. Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. Most crop plants can convert sunlight and CO2 into plant biomass at
