Discovery reveals a key mechanism that all living things use to transport a trace element essential for survival – ScienceDaily

Most people do not think much about zinc. But all living things need zinc for survival. This trace element helps many proteins fold into the right shapes to do their jobs. And in proteins known as enzymes, zinc helps catalyze chemical reactions – including many important for providing energy to cells. If zinc is absent, … Read more

Scientists grow plants in soil from the Moon – ScienceDaily

Scientists have grown plants in soil from the Moon, a first in human history and a milestone in lunar and space exploration. In a new paper published in the journal Communications Biology, University of Florida researchers showed that plants can successfully sprout and grow in lunar soil. Their study also investigated how plants respond biologically … Read more

Bali-like temperatures in Wyoming? Fossils reveal tropically hot North America 95 million years ago – ScienceDaily

A new University of Michigan study that used fossil oyster shells as paleothermometers found the shallow sea that covered much of western North America 95 million years ago was as warm as today’s tropics. The study provides the first direct temperature data from that vast mid-latitude sea during the height of the Cretaceous Thermal Maximum, … Read more

Previously unmapped reservoirs could speed glaciers, release carbon – ScienceDaily

Many scientists say that liquid water is a key to understanding the behavior of the frozen form found in glaciers. Melt water is known to lubricate their gravelly bases and hasten their march toward the sea. In recent years, researchers in Antarctica have discovered hundreds of interconnected liquid lakes and rivers cradled within the ice … Read more

If they can escape death in poachers’ nets, the endangered marine mammal is well poised to rebound despite inbreeding – ScienceDaily

The vaquita porpoise, the world’s smallest marine mammal, is on the brink of extinction, with 10 or fewer still living in Mexico’s Gulf of California, their sole habitat. But a genetic analysis by a team of UCLA biologists and colleagues has found that the critically endangered species remains relatively healthy and can potentially survive – … Read more

Scientists use recycled glass waste as sand replacement in 3D printing – ScienceDaily

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction. Glass is one material that can be 100 per cent recycled with no reduction in quality, yet it is one of the least recycled … Read more

Scientists model landscape formation on Titan, revealing an Earth-like alien world – ScienceDaily

Saturn’s moon Titan looks very much like Earth from space, with rivers, lakes, and seas filled by rain tumbling through a thick atmosphere. While these landscapes may look familiar, they are composed of materials that are undoubtedly different – liquid methane streams streak Titan’s icy surface and nitrogen winds build hydrocarbon sand dunes. The presence … Read more

Lasers trigger magnetism in atomically thin quantum materials – ScienceDaily

Researchers have discovered that light – in the form of a laser – can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons. These subatomic particles have an electronic property called “spin,” which has a potential application in quantum computing. The researchers found that electrons within … Read more

In the race to solve Alzheimer’s disease, scientists find more needles in the haystack – ScienceDaily

21 million. That’s the number of genetic variations in the human genome that researchers are sifting to identify patterns predisposing people to Alzheimer’s disease. It’s a huge haystack, and Alzheimer’s-related genetic variations, like needles, are miniscule in comparison. Sudha Seshadri, MD, and other faculty at The University of Texas Health Science Center at San Antonio … Read more

Scientists demonstrate that some tropical plants have potential to remove toxic heavy metals from the soil – ScienceDaily

A team of researchers from Nanyang Technological University, Singapore (NTU Singapore) and Singapore’s National Parks Board (NParks), has demonstrated that some plant species could help remove toxic heavy metals and metalloids from contaminated soil. Phytoremediation is the use of plants to extract and store contaminants from soil. As a first step to determine if candidate … Read more
