Classical robots, such as those used for manufacturing, can lift heavy loads and repeat automated processes precisely. But they are too rigid and bulky for delicate work and interaction with humans. The research field of soft robotics works on the development of robots made of soft, organic materials and flexible technical components. Materials researchers at Kiel University have now developed a...
The nitrogen cycle, one of the most important biochemical cycles in all ecosystems, plays a key role in human survival and development. It describes the interconversion process between elementary nitrogen substances and nitrogen-containing compounds in nature. Undoubtedly, the redox reactions between these nitrogen-containing molecules maintain the balance of the nitrogen cycle. However, over the...
Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic. This is the result of a recent study by an international research group led by paleobiologist Patrick L....
In July 2021, unprecedented heavy rainfall occurred in Zhengzhou (east-central China) against a background of a northward shift in the western Pacific subtropical high (WPSH), which is a key atmospheric circulation system affecting the East Asian summer climate.
A study by researchers from the UPF Culture, Archaeology and Socio-Ecological Dynamics Research Group (CaSEs), recently published in the journal PLOS ONE, provides a global assessment of traditional small-scale farming practices for three of the world's most important drought-tolerant species: finger millet, pearl millet and sorghum.
An unusual whale feeding technique first documented by scientists in the 2010s may have actually been described in ancient texts two millennia ago, researchers say. Researchers from Flinders University identified striking parallels between the behaviour of tread-water feeding and a sea creature named hafgufa from 13th century Old Norse texts. It is thought hafgufa can be traced back to the...
For the first time, researchers develop a metabarcoding technology for brittle stars. Japanese scientists, led by Dr. Masanori Okanishi of the Hiroshima Shudo University and the University of Tokyo, analyzed environmental DNA (eDNA) released from marine invertebrates in the water, and successfully identified the species they were looking for. The study is published in Metabarcoding and...
As of December 2021, a total of 252 planetary probes have been launched around the world.
The mahogany trees Cedro and Caoba (Cedrela odorata and Swietenia macrophylla) affect the right-forewing of their unwelcome guest, the mahogany shoot borer, which could later influence its flying abilities and help with pest management, a new study shows.
High-power lasers now create record-high numbers of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts.
An updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness, has been published on February 28 in the open access journal PLOS Biology, authored by Rikki Gumbs from the Zoological Society of London (ZSL), U.K., and colleagues.
A review of evidence from prior research provides new support for the possibility that the evolution of larger brains in some species was enabled through increased energy investment by parents in their offspring. Carel van Schaik of the Max Planck Institute for Animal Behavior in Konstanz, Germany, and colleagues present their arguments in a paper published on February 28 in the open access...
Scientists from Skoltech and other research centers have systematically studied the toxicity of materials used in perovskite solar cells. They conclude that, once the remaining technological hurdles are overcome, mass production of this potentially cheap and efficient alternative to silicon-based photovoltaics should not cause any significant environmental risks and health hazards. Reported in...
Many invasive plant species have not yet filled their potentially suitable habitat. This is what geographers at Leipzig University established in a recent simulation study. They coupled different data sets to predict the probability of occurrence of selected invasive plant species for any location in Germany. The results have been published in the International Journal of Applied Earth Observation...
Next time you drive past farms or prairies and ponds on a rural road, look around. They are a rich source of biomass. That includes corn, soybeans, sugar cane, switchgrass, algae and other plant matter. These carbon-rich materials can be converted to liquid fuels and chemicals with many possible applications. There is enough biomass in the United States, for example, to produce renewable jet fuel...
Researchers from the University of Cambridge have analyzed more than 800,000 tweets and found that negative emotions expressed about geoengineering—the idea that the climate can be altered using technology—can easily fall into conspiracy.
