Scientists from the Denver Museum of Nature & Science and Liverpool John Moores University in England have discovered the first adult T. rex trackway, providing insights into how this emblematic predator moved. The findings are published in the Journal of Vertebrate Paleontology.
The moon may have formed in as few as five hours after the cataclysmic collision between Earth and a long-lost protoplanet, new simulations suggest. The surprising findings could help shed light on other historic impacts throughout our cosmic neighborhood and beyond.Experts strongly suspect that the moon was created when a Mars-size space rock called Theia smashed into an early version of our planet, back when the solar system was young and extremely unstable. This colossal impact likely would have turned the once-neighboring worlds into spinning clumps of molten rock that eventually coalesced and cooled into the versions of Earth and the moon we see today. Without this collision, which also...
Indonesia's Mount Anak Krakatau has erupted again this week, sending plumes of volcanic ash high into the sky and disrupting hundreds of flights. More than 300,000 passengers have been affected.
Microplastics are plastic particles smaller than 5 millimeters that originate either from manufactured products or from the breakdown of larger plastic items. They can now be found everywhere, from oceans and rivers to soils and indoor air. Because most plastics degrade very slowly, these particles can remain in the environment for decades or centuries.
As countries compete for skilled workers and grapple with aging populations and labor shortages, understanding who is moving across borders is increasingly important. A new study provides the first global data set of immigration composition disaggregated simultaneously by age, sex and educational attainment, offering a new basis for tracking brain gain and brain drain and improving population projections.
An international team of scientists has recreated a 1,000-year timeline documenting ecological changes and human impact on the area surrounding Crawford Lake, the famed location of the proposed Anthropocene.
Drinking this year's champagne might cause a heftier headache as France's record heat waves force some producers to increase alcohol levels, industry officials said Wednesday.
An experimental compound called AP503 significantly strengthened bones in mice by activating GPR133, a receptor that boosts bone formation while slowing bone loss. Because the same treatment has also been linked to stronger muscles, researchers see intriguing potential for combating age-related decline and osteoporosis.
Cannibalism was sometimes on the Neolithic menu, as numerous archaeological discoveries have revealed. But while ancient human bones show the practice took place, far less evidence exists about the forms it may have taken or why people occasionally consumed one another. Was it to stave off hunger during times of desperation? Did different tribes eat their defeated enemies? Or was cannibalism part of complex rituals?
The birds are up with the sunrise—warblers, flycatchers, sparrows and towhees calling across the treetops. Deer browse on tender buds emerging from dense shrubs. Black bears scrounge for roots, insects and other edibles.
Electronic voting, the use of electronic systems to cast, record or count votes, could potentially simplify the process of electing new political leaders or other representatives. While some countries have already started using internet-connected devices or electronic voting machines at polling stations, the trustworthiness, security and anonymity of electronic voting systems are still widely debated.
In research published in the journal Physical Chemistry Chemical Physics, the electronic structures of organic molecules containing sp2-hybridized carbons in organic solvents were studied using C K-edge X-ray absorption spectroscopy (XAS), termed "Soft-XAS-OS."
