Munich, 4 June 2024 – According to the World Wildlife Fund (WWF), the pulp and paper industry is one of the largest industrial sectors in the world and has an enormous influence on global forests. This sector accounts for 13–15% of total wood consumption and uses between 33–40% of all industrial wood traded globally. In search of more sustainable solutions for paper production, 23-year-old Ukrainian inventor Valentyn Frechka developed a method for recycling leaf litter into paper. Frechka is a finalist for the Young Inventors Prize of the European Inventor Award 2024, in recognition of his promising work towards a circular economy and addressing one of the United Nations’ Sustainable Development Goals (SDGs). He was selected from over 550 candidates for this year’s edition.

Using new technology to recycle fallen leaves into paper

The global loss of trees is known to significantly exacerbate climate change, increasing air pollution levels, causing the loss of biodiversity, and disrupting the water cycle. Global warming also leads to issues such as soil erosion and reduced freshwater availability. It also increases costs for managing environmental problems such as flooding.

Would you swallow a micro-robot? In a gutsy demo, physician Vivek Kumbhari navigates Pillbot, a wireless, disposable robot swallowed onstage by engineer Alex Luebke, modeling how this technology can swiftly provide direct visualization of internal organs. Learn more about how micro-robots could move us past the age of invasive endoscopies and open up doors to more comfortable, affordable medical imaging. (This talk contains medical imagery.)

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have now derived universal rules to enable the de novo design of optimal enzymes.

The paper is published in the journal Chem Catalysis.

As an example, they considered the of breaking a dimer into two monomer molecules. Considering the geometry of such an enzyme-substrate-complex, they identified three golden rules that should be considered to build a functional enzyme.

Nvidia is in advanced talks to invest in PsiQuantum, a quantum computing startup, according to a person involved in the discussions. The investment would be the latest signal that Nvidia has shifted its stance on quantum computing after CEO Jensen Huang earlier this year seemed to cast doubt on…

Interestingly, however, despite Komatsu’s early lead, Vermeer and Interlune seem to have caught up and could be ahead. For example, the new prototype is bigger and full-scale, showing great promise through testing.

The Vermeer-Interlune excavator has a larger excavation capacity, more funding and government support. To this end, Interlune is targeting a lunar mission by 2030.

“The high-rate excavation needed to harvest helium-3 from the moon in large quantities has never been attempted before, let alone with high efficiency,” said Gary Lai, Interlune co-founder and CTO.

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have detected water ice in a debris disk around HD 181327—a young star located within 160 light years away from the Earth. The finding was reported in a paper published May 14 in the journal Nature.

Debris disks are collections of small bodies around stars, including asteroids, Kuiper belt objects, comets, and also micron-sized debris dust. Observations of debris disks could help us better understand the evolution of planetary systems, the composition of dust, comets, and planetesimals outside our solar system.

Given that water plays a key role in the formation of planets and minor bodies, astronomers look for its presence also in debris disks. However, although water ice has been commonly detected in Kuiper belt objects and comets in the solar system, no definitive evidence for water ice in extrasolar debris disks has been found to date.
