Researchers at the Hokkaido University in Japan have revealed a new paste-based method for producing Grignard reagents which are largely used across the chemical industry. This method is simpler, environment-friendly, has the capacity to reduce the use of hazardous organic solvents as well as has the potential to lower production costs.
Scientists at the Global Center for Biomedical Science and Engineering have revealed that the molecular mechanism regulating the trafficking of lysosomes increases the invasiveness and metastasis of radioresistant cancer cells following radiotherapy.
Scientists at Hokkaido University and colleagues in Japan have demonstrated a quick and effective mass testing approach using saliva samples to detect individuals who have been infected with Covid-19 but are still not showing symptoms.
Scientists in Japan have developed an ultrastable, selective catalyst which proves beneficial for the propane dehydrogenation process without deactivation. This process is essential to produce the vital petrochemical substance of propylene.
Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against Sars-Cov-2, the causative virus of Covid-19.
Hokkaido University researchers have developed a hydrogel that does the opposite of what polymer-based materials, like plastic bottles, normally do: their material hardens when heated and softens when cooled. Their findings, published in the journal Advanced Materials, could lead to the fabrication of protective clothing items for traffic and sports-related accidents.
Early snowmelt increases the risk of phenological mismatch, in which the flowering of periodic plants and pollinators fall out of sync, compromising seed production. Gaku Kudo of Hokkaido University and Elisabeth J. Cooper of the Arctic University of Norway have demonstrated that early snowmelt results in the spring ephemeral Corydalis ambigua flowering ahead of the emergence of its pollinator, the bumblebee.
International Scientists have employed a new method utilizing tsunami signals to calculate the calving magnitude of an ocean-terminating glacier in northwestern Greenland, uncovering correlations between calving flux and environmental factors such as air temperature, ice speed, and ocean tides.
