Molecular motors are complex devices composed of many different parts that consume energy to perform various cellular activities. In short, molecular machines transform energy into useful work. Understanding the mechanistical aspects underlying these motors begins with generating a detailed description of their overall architecture and atomic organisation. However, to uncover the core mechanisms energizing these motors it is essential to decode all of the molecular dynamics in atomic detail. Now, the research team of Thomas C. Marlovits from the Centre for Structural Systems Biology CSSB at DESY and the University Medical Center Hamburg-Eppendorf (UKE) in Hamburg reveals the architecture, complete functional cycle and the mechanism of such a molecular motor: They report in the journal Nature, how a 'RuvAB branch migration...

PPE can be recycled to make stronger concrete

by TMR Desk

Engineering

Engineers at RMIT University have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste. The RMIT team is the first to investigate the feasibility of recycling three key types of PPE -- isolation gowns, face masks and rubber gloves -- into concrete. Published in the journals Case Studies in Construction Materials, Science of the Total Environment and Journal of Cleaner Production, the studies by RMIT School of Engineering researchers demonstrate the potential for PPE to be used as reinforcement materials in structural concrete. The studies found shredded PPE could increase the strength of concrete by up to 22% and improve resistance to cracking. The RMIT School of Engineering team's industry partner, Casafico Pty Ltd,...

Comet impacts formed continents when Solar System entered arms of Milky Way

by TMR Desk

Engineering

New Curtin research has found evidence that Earth's early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet's formation on its head. The new research, published in Geology, challenges the existing theory that Earth's crust was solely formed by processes inside our planet, casting a new light on the formative history of Earth and our place in the cosmos. Lead researcher Professor Chris Kirkland, from the Timescales of Mineral Systems Group within Curtin's School of Earth and Planetary Sciences, said studying minerals in the Earth's crust revealed a rhythm of crust production every 200 million years or so that matched our Solar...

Tracking the journey of mangroves in southern Japan

by TMR Desk

Water

Mangroves are salt-tolerant trees found in the coastal waters of the tropics and subtropics around the world. Mangrove forests play vital roles for both nature and society. They help protect coastal communities as they provide a natural barrier from tsunamis and storms. In the other direction, they filter pollution and soil runoff. These forests also provide a marine nursery ground as the juveniles of coastal fish can easily hide between the trees. And they have an important role as a carbon sink, thus mitigating climate change. But today, around the world, mangroves are in decline. The forests are often removed to make way for farms and urban developments. To establish which of the remaining forests are the most important to...

Global warming spawned the age of reptiles

Climate Change

Studying climate change-induced mass extinctions in the deep geological past allows researchers to explore the impact of environmental crises on organismal evolution. One principal example is the Permian-Triassic climatic crises, a series of climatic shifts driven by global warming that occurred between the Middle Permian (265 million years ago) and Middle Triassic (230 million years ago). These climatic shifts caused two of the largest mass extinctions in the history of life at the end of the Permian, the first at 261myo and the other at 252myo, the latter eliminating 86% of all animal species worldwide. The end-Permian extinctions are important not only because of their magnitude, but also because they mark the onset of a new era in the history of...

Scientists develop new method to assess ozone layer recovery

by TMR Desk

Engineering

Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone layer. Published in the journal Nature, their method -- the Integrated Ozone Depletion (IOD) metric -- provides a useful tool for policymakers and scientists. The IOD has been designed to provide a straightforward way to measure the effects of unregulated emissions of substances that deplete the ozone layer, and evaluate how effective ozone layer protection measures are. The ozone layer is found in a region of the earth's atmosphere known as the stratosphere, and acts as an important protection barrier against most of the sun's harmful ultraviolet rays. Ozone depleting gases such as chlorofluorocarbons, better known as CFCs, have been phased out under the Montreal...

1cr people in Bangladesh at risk of climate change hunger in 2030

by TMR Desk

Climate Change

Climate change and a trembling global situation are posing an increasing risk and direct threat of starvation for one crore people in Bangladesh, the International Food Policy Research Institute (IFPRI) warns. The international organisation, in its "2022 Global Food Policy Report: climate change and food system", launched at a hotel in Dhaka, highlighted that in Bangladesh, climate change will reduce agricultural productivity and disrupt supply chains, putting pressure on livelihoods, threatening to significantly increase hunger and malnutrition. Disruption in the export-import of goods and a price hike in agricultural equipment due to ongoing war situations and a global economic downturn will also cut agricultural productivity in the country, it added. For the aforementioned reasons, the impact of climate change will pose a threat...

$230 bn needed by 2030 to implement National Action Plan on climate change

by TMR Desk

Climate Change

Minister for Environment, Forest and Climate Change Shahab Uddin today (August 28) said Bangladesh requires USD 230 billion by 2030 to implement various activities to tackle climate change. Under the newly formed National Action Plan on Climate change, the minister said, a total of 113 types of activities were identified under eight thematic areas. Certainly, the government of Bangladesh will mobilise domestic resources to implement those activities, he said. "But, without international and bilateral support, it would be very difficult for us to implement and attain climate resilience," the minister said. We are looking forward to the USD 100 billion funding committed by the developed countries to tackle climate change. Shahab Uddin said this in the conference room of the ministry while a delegation led...
