When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, including humans and some aquatic vertebrates such as whales and dolphins.

By 2050, more than half the global population will live downstream from tens of thousands of large dams near or past their intended lifespan, according to a UN report released Friday.

Alongside Dennis van Engelsdorp, associate professor at the University of Maryland (UMD) in Entomology named for the fifth year in a row for his work in honey bee and pollinator health, Yiping Qi, associate professor in Plant Science, represented the College of Agriculture & Natural Resources on the Web of Science 2020 list of Highly Cited Researchers for the first time. This list includes influential scientists based on the impact of their academic publications over the course of the year. In addition to this honor... Читать дальше...

A brief burst of high-energy light swept through the solar system on April 15, triggering many space-based instruments, including those aboard NASA and European missions. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.

By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the 20th century, many of them already operating at or beyond their design life, according to a UN University analysis.

The pressing concern posed by rising sea levels has created a critical need for scientists to precisely predict how quickly the oceans will rise in coming centuries. To gain insight into future ice sheet stability and sea-level rise, new research from an international team led by University of South Florida geoscientists is drawing on evidence from past interglacial periods when Earth's climate was warmer than today.

Collective research to date regarding nutrients found in the leaves of contemporary cycad species has been inconsistent as far as data collection and narrow in scope, according to a University of Guam-led literature review published on Nov. 19 in Horticulturae journal.

Marine microalgae-based cellular agriculture is a promising new way to sustainably produce plant-based 'meat' and healthy 'superfoods' for the future.

Professor Matsuyama Hideto's research group at Kobe University's Research Center for Membrane and Film Technology has successfully developed a new desalination membrane. They achieved this by laminating a two-dimensional carbon material on to the surface of a porous polymer membrane.

The Singapore University of Technology and Design (SUTD) and its research collaborators have successfully demonstrated the four-dimensional (4-D) printing of shape memory polymers in submicron dimensions which are comparable to the wavelength of visible light. This novel development has allowed researchers to now explore new applications in the field of nanophotonics.

A team of researchers affiliated with several institutions in Israel has discovered the means by which salmonella bacteria use a metabolite to reprogram the Krebs cycle to promote their own survival. In their paper published in the journal Science, the group describes their study of the reaction of salmonella to the presence of succinate and what it revealed about the role succinate might play in bacterial infections in general. Jason Lynch and Cammie Lesser with Massachusetts General Hospital, have... Читать дальше...

A team of researchers from the U.K., Germany and Russia has used the unpredictable nature of quantum mechanics to create a device capable of generating truly random numbers. In their paper published in the journal Physical Review Letters, the group describes using aspects of quantum theory to develop a framework for building a truly random number generator.

Edge states are an emerging concept in physics and have been explored as an efficient strategy to manipulate electrons, photons and phonons for next-generation hybrid electro-optomechanical circuits. Scientists have used gapless chiral edge states in graphene or graphene-like materials to understand exotic quantum phenomena such as quantum spin or valley Hall effects. In a new report now published on Science Advances, Xiang Xi and colleagues reported on experimental chiral edge states in gapped nanomechanical... Читать дальше...
