Global carbon dioxide emissions rise even as coal wanes and renewables boom

Renewable energy capacity has hit record levels and global coal use may have already peaked. But the world’s carbon dioxide emissions from fossil fuels increased in 2018, and the trend places global warming targets in jeopardy. Global fossil fuel emissions are on track to rise for a second year in a row, primarily due to … More Global carbon dioxide emissions rise even as coal wanes and renewables boom

Give it the plasma treatment: Strong adhesion without adhesives

A research team has used plasma treatment to make fluoropolymers and silicone resin adhere without any adhesives. Heat-assisted helium-plasma treatment created oxygen-containing functional groups on PTFE or PFA, while open-air plasma-jetting installed silanol groups on vulcanized PDMS. Under pressure, the treated PDMS strongly adhered to the treated polymers, copper, and glass through covalent and hydrogen … More Give it the plasma treatment: Strong adhesion without adhesives

Buzzed flies reveal important step to intoxication

The alcohol in beverages acts much like an anesthetic. It creates a hyper ‘buzzed’ feeling first, and then sedation. But how? It turns out there is an important intermediate step that wasn’t previously known. As New Year’s Eve approaches, many people will experience the familiar buzz that comes from imbibing a favorite cocktail or glass … More Buzzed flies reveal important step to intoxication

How the brain enables us to rapidly focus attention

Researchers have discovered a key mechanism in the brain that may underlie our ability to rapidly focus attention. Our brains are continuously bombarded with information from the senses, yet our level of vigilance to such input varies, allowing us to selectively focus on one conversation and not another. University of Queensland researchers have discovered a … More How the brain enables us to rapidly focus attention

Newborn insects trapped in amber show first evidence of how to crack an egg

Four complete Tragychrysa ovoruptora newborns preserved together with egg shell remains and one visible egg burster (right inset). Credit: Modified from the open access article published in Palaeontology: ‘The hatching mechanism of 130-million-year-old insects: an association of neonates, egg shells, and egg bursters in Lebanese amber’ Amber preserving newborns, egg shells, and egg bursters shows … More Newborn insects trapped in amber show first evidence of how to crack an egg

Bacteria found in ancient Irish soil halts growth of superbugs: New hope for tackling antibiotic resistance

Researchers analyzing soil from Ireland long thought to have medicinal properties have discovered that it contains a previously unknown strain of bacteria which is effective against four of the top six superbugs that are resistant to antibiotics, including MRSA. Antibiotic-resistant superbugs could kill up to 1.3 million people in Europe by 2050, according to recent … More Bacteria found in ancient Irish soil halts growth of superbugs: New hope for tackling antibiotic resistance

Biotechnology Solves Debate Over Origin Of European Potato

For years, researchers have debated the birthplace of the European potato. Recent genetic studies revealed that the earliest known landraces of the European potato contain both Andean and Chilean molecular markers. These findings may change current breeding programs which focus solely on the Andean landraces and not the Chilean landraces, according to scientists. Molecular studies … More Biotechnology Solves Debate Over Origin Of European Potato

New microscopy technique allows mapping protein synthesis in living tissues and animals

Building on previously published research, investigators have advanced technology to allow for time-lapse images of protein synthesis with high spatial-temporal resolution in live cells/tissues and map protein degradation in live cells/tissue. They’ve successfully demonstrated that this technology can be used to image protein synthesis in brain tissues, zebrafish and mice in vivo, making it a … More New microscopy technique allows mapping protein synthesis in living tissues and animals

Researcher improves crop performance with new biotechnology

Researchers have discovered a way to enhance a plant’s tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield. This discovery could be instrumental in agriculture and food security by improving crop sustainability and performance. With the world’s population exploding to well … More Researcher improves crop performance with new biotechnology
