The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.

Tipping elements of the Earth system should be considered global commons, researchers argue. Global commons cannot -- as they currently do -- only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.

Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.

Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.

An innovative study explores the use of robotic-assisted joint replacement in revision knee scenarios, comparing the pre- and post-revision implant positions in a series of revision total knee arthroplasties (TKA) using a state-of-the-art robotic arm system.

This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.

A research team investigated how the emergence of the first living systems from inert geological materials happened on the Earth, more than 3.5 billion years ago. Scientists found that by mixing hydrogen, bicarbonate, and iron-rich magnetite under conditions mimicking relatively mild hydrothermal vent results in the formation of a spectrum of organic molecules, most notably including fatty acids stretching up to 18 carbon atoms in length.

Scientists developed a soft fluidic switch using an ionic polymer artificial muscle that runs with ultra-low power to lift objects 34 times greater than its weight. Its light weight and small size make it applicable to various industrial fields such as soft electronics, smart textiles, and biomedical devices by controlling fluid flow with high precision, even in narrow spaces.

Analysis of iron meteorites from the earliest years of the solar system indicate that the planetary 'seeds' that ultimately formed Earth contained water.

Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.

Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.

The introduction of artificial intelligence is a significant part of the digital transformation bringing challenges and changes to the job descriptions among management. A study shows that integrating artificial intelligence systems into service teams increases demands imposed on middle management in the financial services field. In that sector, the advent of artificial intelligence has been fast and AI applications can implement a large proportion of routine work that was previously done by people. Many professionals in the service sector work in teams which include both humans and artificial intelligence systems, which sets new expectations on interactions, human relations, and leadership.

An artificial intelligence-driven system has autonomously learned about certain Nobel Prize-winning chemical reactions and designed a successful laboratory procedure to make them. The AI did so in just a few minutes and correctly on its first attempt. According to the authors, this is the first time that a non-organic intelligence planned, designed and executed this complex reaction that was invented by humans.

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study.

A tiny, hard-working bacterium -- which weighs one-trillionth of a gram -- may soon have a large influence on processing rare earth elements in an eco-friendly way.

The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two bears to only a few degrees in temperature. A team of astronomers has achieved a world's first by managing to simulate the entirety of the runaway greenhouse process which can transform the climate of a planet from idyllic and perfect for life, to a place more than harsh and hostile. The scientists have also demonstrated that from initial stages of the process, the atmospheric structure and cloud coverage undergo significant changes, leading to an almost-unstoppable and very complicated to reverse runaway greenhouse effect. On Earth, a global average temperature rise of just a few tens of degrees, subsequent to a slight rise of the Sun's luminosity, would be sufficient to initiate this phenomenon and to make our planet inhabitable.

Positive tipping points must be triggered if we are to avoid the severe consequences of damaging Earth system tipping points, researchers say.
