Better understanding of soft artificial muscles

Science Daily - 16/11/2019
Artificial muscles will power the soft robots and wearable devices of the future. But more needs to be understood about the underlying mechanics of these powerful structures in order to design and build new devices. Now, researchers have uncovered some of the fundamental physical properties of artificial muscle fibers.

Amazon deforestation and number of fires show summer of 2019 not a 'normal' year

Science Daily - 16/11/2019
The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was 'normal' and 'below the historical average'. An international team of scientists writing in the journal Global Change Biology say the number of active fires in August was actually three times higher than in 2018 and the highest number since 2010.

Link between inflammation and mental sluggishness shown in new study

Science Daily - 16/11/2019
Scientists have uncovered a possible explanation for the mental sluggishness that often accompanies illness.

Ketogenic diet helps tame flu virus

Science Daily - 16/11/2019
A high-fat, low-carbohydrate diet like the Keto regimen has its fans, but influenza apparently isn't one of them. Mice fed a ketogenic diet were better able to combat the flu virus than mice fed food high in carbohydrates, according to a new study.

Plants use a single communication route when developing new chloroplasts

Science Daily - 16/11/2019
When a plant begins growing its first leaves, it is in a race for survival to build its chloroplasts. Research reveals that a chain of communication from the developing chloroplast to the cell's central DNA center, the nucleus, is controlled in-part by a protein that defied characterization for the past quarter-century and there is also a role for a molecule recently made famous by the plant-based 'meat' industry: plant heme.

New finding offers possibility for preventing age-related metabolic disease

Science Daily - 16/11/2019
A study has uncovered why belly fat surrounding organs increases as people age, a finding that could offer new treatment possibilities for improving metabolic health, thereby reducing the likelihood for diseases like diabetes and atherosclerosis that stem from inflammation.

Squid camouflage may lead to next gen of bio-inspired synthetic materials

Science Daily - 16/11/2019
Squids, octopuses and cuttlefish are undisputed masters of deception and camouflage. Their extraordinary ability to change color, texture and shape is unrivaled, even by modern technology.

How fibrosis progresses in the human lung

Science Daily - 16/11/2019
A study boosts scientific understanding of how the lung disease idiopathic pulmonary fibrosis (IPF) progresses, providing a roadmap for researchers to discover new treatment targets for the disease.

Central mysteries of solar physics

Science Daily - 16/11/2019
Scientists have shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

Bacterial protein impairs important cellular processes

Science Daily - 15/11/2019
Researchers have discovered a new function of antibiotic resistant bacteria.

Digital media has damaging impact on reintegration of 'white collar' criminals

Science Daily - 15/11/2019
Offenders convicted of occupational crime and corruption are having their rehabilitation negatively affected by long term 'labels' attached to them on digital media, according to new research.

Secret of explosive volcanism unlocked

Science Daily - 15/11/2019
When will the next eruption take place? Examination of samples from Indonesia's Mount Merapi show that the explosivity of stratovolcanoes rises when mineral-rich gases seal the pores and microcracks in the uppermost layers of stone. These findings result in new possibilities for the prediction of an eruption.

Chemists map an artificial molecular self-assembly pathway with complexities of life

Science Daily - 15/11/2019
Two pathways diverged in a chemical synthesis, and one molecule took them both. Chemists have studied how molecular building blocks can either form a spherical cage or an ultrathin sheet that shows some of the basic properties of a ''smart'' material that can respond to its environment.

New cell therapy improves memory and stops seizures following TBI

Science Daily - 15/11/2019
Researchers have developed a breakthrough cell therapy to improve memory and prevent seizures in mice following traumatic brain injury.

How nematodes outsmart the defenses of pests

Science Daily - 15/11/2019
The western corn rootworm, one of the world's most damaging maize pests, can use plant defense compounds to defend itself against its own natural enemies, so-called entomopathogenic nematodes. However, the nematodes can become immune against these compounds in turn, which enhances their ability to fight the western corn rootworm, as researchers show. This mechanism may contribute to improving biological pest control.

Fecal transplantation to treat patients with Parkinson's disease: Hope or hype?

Science Daily - 15/11/2019
Constipation is a common complaint in patients with Parkinson's disease (PD). Fecal microbiome transplantation (FMT) and pre- and probiotics are potential options for treating constipation and restoring the microbiome of patients with Parkinson's disease (PD), but scientists warn that clinical data are scarce, and more research is needed before supporting their use.
