Healthy muscles are a carrot on a string for healthy lungs

Scientists show effectiveness of carrot-based Japanese herbal medicine called ‘Ninjin’yoeito’ in improving muscle atrophy in the hind legs of mice exposed to cigarette smoke, positioning the medicine as a potential treatment for sarcopenia frailty-related complications with chronic obstructive pulmonary disease (COPD).

SMART researchers develop plant nanobionic sensor to monitor arsenic levels in soil

(Singapore-MIT Alliance for Research and Technology (SMART)) Researchers from Singapore-MIT Alliance for Research and Technology (SMART) have developed — for the first time — a novel type of plant nanobionic optical sensor that can, in real-time, detect and monitor arsenic levels in the belowground environment, with significant advantages over conventional methods used to measure arsenic in the environment. The new sensor will improve arsenic detection and will help safeguard food safety, and will be useful for agricultural research and environmental monitoring.

Watching the Arctic thaw in fast-forward

The frozen permafrost in the Arctic is thawing on an alarming scale. By analyzing an annual record of satellite images, researchers have now confirmed these findings: thermokarst lakes in Alaska are draining one by one because warmer and wetter conditions cause deeper thaw, effectively weakening frozen ground as a barrier around lakes. In the season 2017/2018, lake drainage was observed on a scale that scientists didn’t expect until the end of the century.

Warning signs over effectiveness of HIV ‘wonder drug’ in sub-Saharan Africa

Dolutegravir, the current first-line treatment for HIV, may not be as effective as hoped in sub-Saharan Africa, suggests new research published on World AIDS Day. The study finds that this so-called ‘wonder drug’ may be less effective in patients resistant to older drugs.

Experimental vaccine for deadly tickborne virus effective in cynomolgus macaques

An experimental vaccine developed in Europe to prevent infection by Crimean-Congo hemorrhagic fever virus (CCHFV) has protected cynomolgus macaques in a new collaborative study. The study comes about three years after the same research group developed the macaque model for CCHFV. No specific treatments or vaccines for CCHFV exist.

Area burned by severe fire increased 8-fold in western US over past four decades

The number of wildfires and the amount of land they consume in the western US has substantially increased since the 1980s, a trend often attributed to ongoing climate change. Now, new research finds fires are not only becoming more common in the western US but the area burned at high severity is also increasing, a trend that may lead to long-term forest loss.

Which factors trigger leaf die-off in autumn?

Researchers have identified a self-regulating mechanism in European deciduous trees that limits their growing-season length: Trees that photosynthesize more in spring and summer lose their leaves earlier in autumn.

Jaguars robust to climate extremes but lack of food threatens species

Researchers lead a world-first investigation into the chances of wild jaguars surviving climate extremes with six scenarios modelling the behavior, mating, births of cubs, competition, illegal hunting, death from starvation and availability of prey.
