Scientists develop novel RNA- or DNA-based substances to protect plants from viruses      (via sciencedaily.com)     Original source 

Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study. The researchers were able to fend off a common virus using the new active substances in up to 90 per cent of cases. They also developed a method for finding substances tailored specifically to the virus. The team has now patented the method.

Researchers create new compound to build space-age antennas      (via sciencedaily.com)     Original source 

In a first-of-its-kind development, researchers have created a new compound that can be used to 3D print telecommunication antennas and other connectivity devices. These 3D printed products, created by combining a two-dimensional compound called MXenes with a polymer, can be used as an alternative for metallic counterparts and can make a vast improvement in communication technology including elements such as antennas, waveguides and filters.

Small dietary changes can cut your carbon footprint by 25%      (via sciencedaily.com)     Original source 

New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.

A new plant's name that tells a story      (via sciencedaily.com)     Original source 

A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.

A bright idea for recycling rare-earth phosphors from used fluorescent bulbs      (via sciencedaily.com)     Original source 

Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.

The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus      (via sciencedaily.com)     Original source 

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.

New tool helps decipher gene behavior      (via sciencedaily.com)     Original source 

Scientists have extensively researched the structure and sequence of genetic material and its interactions with proteins in the hope of understanding how our genetics and environment interact in diseases. This research has partly focused on 'epigenetic marks', which are chemical modifications to DNA, RNA, and the associated proteins (known as histones).

In fight against brain pathogens, the eyes have it      (via sciencedaily.com)     Original source 

The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into the eyes of mice can help disable the herpes virus, a major cause of brain encephalitis. To their surprise, the vaccine activates an immune response through lymphatic vessels along the optic nerve.
