A new temperature-responsive smart material is 1,800 times stiffer than the original hydrogel when heated

A new material that stiffens 1,800-fold when exposed to heat could protect motorcyclists and racecar drivers during accidents. 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

Slowing agricultural methane emissions is vital for the ongoing health of the planet and sustaining economies

An international research collaboration has made an important discovery in the quest to help lower global agricultural methane emissions. The team has identified new processes that control methane production in the stomach (rumen) of sheep and other ruminants. Specifically, they determined the microbes and enzymes that control supply of hydrogen, the main energy source for

Manufacturing of biobased plastics gets easier

A one-step method enables scalable and more environmentally friendly production of plant-derived plastic monomers, paving the way towards the mass production of a sustainable alternative to petroleum-based materials. An international team, including Kiyotaka Nakajima of Hokkaido University, Japan, and Emiel Hensen of Eindhoven University of Technology, the Netherlands, has developed an energy-efficient method to synthesize

The swarming behavior of about 100 million molecular machines can be controlled by simple mechanical stimuli

The swarming behavior of about 100 million molecular machines can be controlled by applying simple mechanical stimuli such as extension and contraction. This method could lead to the development of new swarming molecular machines and small energy-saving devices. The swarming molecules in motion aligned in one direction, exhibited zigzag patterns, or formed a vortex responding

An engineered virus kills cancer cells more effectively than another virus currently used in treatments

An engineered virus kills cancer cells more effectively than another virus currently used in treatments, according to Hokkaido University researchers. Hokkaido University researchers have engineered a virus that selectively targets and kills cancer cells. The virus, called dl355, has an even stronger anticancer effect than another engineered virus currently used in clinical practice, according to

New material becomes stronger in response to mechanical stress – mimicking skeletal muscle growth

A strategy inspired by the process responsible for muscle growth could lead to the development of stronger, longer-lasting materials. Hokkaido University researchers have developed a strategy to fabricate materials that become stronger in response to mechanical stress – mimicking skeletal muscle growth. Their findings, published in the journal Science, could pave the way for long-lasting

A robot capable of immediately adapting to unexpected physical damage

Researchers at Tohoku University and Hokkaido University have, for the first time, succeeded in developing a robot capable of immediately adapting to unexpected physical damage. This is a significant breakthrough as robots are increasingly expected to function in tough environments under hazardous conditions. Conventional robots tend to require a considerable amount of time (several tens

Developing satellites that can fix other satellites

For his latest study, professor Ou Ma engineered robots to work independently but collaboratively When satellites break, which is surprisingly often, there isn’t much you can do about them. They become expensive and dangerous flotsam, orbiting Earth for years or generations until gravity eventually draws them to a fiery death in the atmosphere. University of

Predict the global spread of dengue with a new tool

Researchers at CSIRO, Australia’s national science agency, QUT and Queensland Health have developed a new tool to predict the global spread of human infectious diseases, like dengue, and track them to their source. The tool draws on travel data from the International Air Transportation Association and dengue incidence rates from the Global Health Data Exchange

Drones show the evidence that the Greenland ice sheet is getting more unstable as it fractures

The world’s second-largest ice sheet, and the single largest contributor to global sea level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface. Using custom-built drones strong enough to withstand the extreme Arctic conditions, researchers led by the University of Cambridge made
