Where did Earth’s water come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents’ Professor in ASU’s School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has found an answer in a previously neglected source. The team has also discovered that our planet contains considerably more hydrogen, a ...
The potentially rocky planet, known as Barnard’s star b, is a “super-Earth” with a mass of at least 3.2 times that of the Earth, and it orbits around its host star once every 233 days. The results, published in the journal Nature, show the planet lies at a distant region from the star known as the ...
Scientists at The University of Texas at Austin’s Marine Science Institute have discovered nearly two dozen new types of deep-sea microbes, many of which use hydrocarbons, such as methane and butane, as energy sources to survive and grow — meaning the newly identified bacteria might be helping to limit the concentrations of greenhouse gases in ...
If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that lasers on Earth could, in principle, be fashioned into something of a planetary porch light — a beacon strong enough to attract attention from as far as 20,000 light-years away. The research, which author James Clark calls a “feasibility study,” appears ...
Climate change may be occurring even faster than first thought. That is according to a ground-breaking new study by Dr. Clayton Magill from the Lyell Centre at Heriot-Watt University in Scotland. Scientists measured the vast migration of sea bed materials, such as clay and sand, a process that occurs over thousands of years. The research ...
Currently, half of the world’s measured annual rain falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By the century’s end, climate models project that this lopsided distribution of rain and snow is likely to become even more skewed, with half of the annual precipitation ...
After a Chinese scientist claimed to have edited genes of babies, authorities have halted all human gene-editing research in the country. Meanwhile, the scientist has apparently been missing for the past several days. The breakthrough and the backlash against the Chinese scientist In November last month, He Jiankui, a professor from the Southern University of Science ...
A dead whale, washed ashore in eastern Indonesia, surprised environmentalists when they discovered that the creature had 115 plastic cups in its stomach. Four plastic bottles, 25 plastic bags, a nylon sack, and 1,000 other plastic items were also found inside. In total, about 13 pounds of plastic waste was recovered. The dead whale “Although ...
An international research team, including The Australian National University (ANU), has used the Kepler space telescope in coordination with ground-based telescopes to witness the first moments of a star dying in unprecedented detail. The astronomers witnessed the star dying a long time ago in a galaxy far, far away, as part of a project that ...
New research disputes a long-held view that our earliest tool-bearing ancestors contributed to ancient mammal extinctions in Africa over the last several million years. Instead, the researchers argue that long-term environmental change drove these mammal extinctions, mainly in the form of grassland expansion likely caused by falling atmospheric carbon dioxide (CO2) levels. Tyler Faith, curator ...
