A paralyzed man who cannot speak or type was able to spell out over 1,000 words using a neuroprosthetic device that translates his brain waves into full sentences, US researchers said Tuesday.
A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate.
According to the new paper, 16 of 35 planetary vital signs have now reached record extremes. That includes rises in the frequency of dangerous heat events, global tree cover loss from fires and the prevalence of the mosquito-borne dengue virus.
The global population is closing on 8 billion, and the amount of land available for human burial is running out. To minimise environmental impact, human bodies should return to nature as quickly as possible.
NASA scientists, using a tool designed to study how dust affects climate, have identified more than 50 spots around the world emitting major levels of methane, a development that could help combat the potent greenhouse gas.
A large spike in radiocarbon found in trees around the world means an uptick in cosmic radiation.
An international group of researchers have achieved dizzying data transmission speeds and are the first in the world to transmit more than 1 petabit per second (Pbit/s) using only a single laser and a single optical chip.
Quantum brain processes could explain why we can still outperform supercomputers when it comes to unforeseen circumstances, decision making, or learning something new, while the discovery may also shed light on consciousness.
Researchers looked at soil and lake sediment from Lake Hazen, the largest lake by volume north of the Arctic Circle. Sequencing segments of DNA and RNA found in the soil, the scientists sought to identify the pool of viruses present in the environment.
By bringing pure water into contact with an electron-sharing alkali metal – in this case an alloy of sodium and potassium – free-moving charged particles can be added, turning water metallic.
Austrian glaciers have also lost more glacial ice in 2022 than they have in 70 years of observations and therefore it is quite clear that severe melt has been the norm in 2022.
A major essay in a prestigious, peer-reviewed scientific journal argues that oceans are a “living entity” entitled to rights. The “Ocean rights” approach would make the creatures of the sea co-equal with humans.
In the atmospheres of exoplanets WASP-76b and WASP-121b drift clouds of barium was found. The answer to the question "why is there such a heavy element in the upper layers of the atmosphere of these planets?" is unknown.
A team of US. scientists found huge ripples at the edge of the Solar System, on the scale of tens of astronomical units.
Technically referred to as sedaDNA – for sedimentary ancient DNA – the recovered samples are likely to prove useful in the ongoing efforts to understand how climate change could affect Antarctica in the future.
