Sweet move: a modified sugar enhances antisense oligonucleotide safety and efficacy      (via sciencedaily.com)     Original source 

Researchers found that adding a newly developed modified sugar, BNAP-AEO, to gapmer antisense oligonucleotides (ASOs) increased their affinity for target RNAs, thus significantly enhancing their gene-silencing effects in vitro and in vivo. The BNAP-AEO modification also decreased gapmer ASO toxicity to the central nervous system (CNS), suggesting that it could improve the clinical application of ASO treatment of CNS disease.

Roots are a key to drought-tolerant maize      (via sciencedaily.com)     Original source 

Maize can grow successfully in very different local conditions. An international study has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably -- depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in the plant's ability to adapt. This gene could be the key to developing varieties of maize that cope better with climate change.

Cuddled cows who work as therapy animals showed a strong preference for women compared to men, study finds      (via sciencedaily.com)     Original source 

A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.

Flexible film senses nearby movements -- featured in blink-tracking glasses      (via sciencedaily.com)     Original source 

I'm not touching you! When another person's finger hovers over your skin, you may get the sense that they're touching you, feeling not necessarily contact, but their proximity. Similarly, researchers have designed a soft, flexible film that senses the presence of nearby objects without physically touching them. The study features the new sensor technology to detect eyelash proximity in blink-tracking glasses.

New insights into the degradation dynamics of organic material in the seafloor      (via sciencedaily.com)     Original source 

Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.

Ethylene from CO2: Building-kit catalyst      (via sciencedaily.com)     Original source 

Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. Nitrogen atoms with a particular electron configuration play a critical role for the catalyst.

Study finds widespread 'cell cannibalism,' related phenomena across tree of life      (via sciencedaily.com)     Original source 

Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals.

Detecting odors on the edge: Researchers decipher how insects smell more with less      (via sciencedaily.com)     Original source 

While humans feature a sophisticated sense of smell, insects have a much more basic olfactory system. Yet they depend upon smell to survive. Scientists have figured out how fruit flies use a simple but efficient system to recognize odors, and the answer lies at the edges of their antennae.

Drug-like inhibitor shows promise in preventing flu      (via sciencedaily.com)     Original source 

Currently available flu medications only target the virus after it has already established an infection, but what if a drug could prevent infection in the first place? Now, scientists have designed drug-like molecules to do just that, by thwarting the first stage of influenza infection.

Batteries: Modeling tomorrow's materials today      (via sciencedaily.com)     Original source 

Which factors determine how quickly a battery can be charged? Microstructural models have helped researchers discover and investigate new electrode materials. When sodium-nickel-manganese oxide is used as cathode material in sodium-ion batteries, simulations reveal modifications of the crystal structure during charging. These modifications lead to an elastic deformation, as a result of which capacity decreases.
