Saturn"s moon is a testing ground to gain a better understanding of the methane molecule
Titan is the second-largest moon in the solar system and the only one with a dense atmosphere. At the top of this atmosphere, rich in nitrogen and methane, the sun's radiation produces a great diversity of organic molecules, some of which we also fin.....»»
New type of tunable filter reveals the potential for terahertz wireless communications
Electromagnetic waves in the terahertz frequency range offer many advantages for communications and advanced applications in scanning and imaging, but realizing their potential poses challenges. Researchers at Tohoku University have addressed one of.....»»
Global warming may be behind an increase in the frequency and intensity of cold spells
Global warming caused by increased concentrations of greenhouse gases is already affecting our lives. Scorching summers, more intense heat waves, longer drought periods, more extended floods, and wilder wildfires are consequences linked to this warmi.....»»

Investigating cell killers: An advanced system for size-dependent cytotoxicity analysis of silica
Metal nanomaterials have become an indispensable part of industrial and medical fields due to their unique and versatile properties. Their size, which imparts them with the desired physiochemical properties, is also the reason for environmental and h.....»»
Radio waves can tune up bacteria to become life-saving medicines
Scientists from Australia and the United States have found a new way to alter the DNA of bacterial cells—a process used to make many vital medicines including insulin—much more efficiently than standard industry techniques......»»
How "the strong force" influences the gravitational wave background
Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe......»»
Could fiber optic cable help scientists probe the deep layers of the moon?
An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth—but how would this technology fare on the moon, and what would it tell us about the deep layers of our nearest neighbor in space?.....»»
Nature"s sonar: Scientists reveal how Japanese horseshoe bats perceive moving objects
Unlike most animals that rely on visual senses, bats navigate and locate prey or obstacles through echolocation. By emitting sounds and comparing them to the reflected echoes, bats can "visualize" movement in the environment. When sound waves encount.....»»
African great apes predicted to see frequent extreme climate events in the next 30 years
African apes are already being exposed to climate change impacts, and will experience extreme events such as wildfires, heat waves and flooding more frequently in the next 30 years, according to a study published February 28 in the open-access journa.....»»
Humanity Is Dangerously Pushing Its Ability to Tolerate Heat
Extreme heat waves are already here, and they are killing tens of thousands of people. Blasting through 2 degrees Celsius of warming means they’ll happen many times more frequently......»»
Tsunami on the plains: Researchers find that sea waves once swept Canadian Prairie Provinces
Hundreds of millions of years ago, an earthquake sent a series of massive waves across the ancient sea that covered part of Western Canada and the northern United States......»»
Meltwater in the north Atlantic can lead to European summer heat waves, study finds
Scientists from the National Oceanography Centre (NOC) have discovered that increased meltwater in the North Atlantic can trigger a chain of events leading to hotter and drier European summers......»»
The best Mac games for 2024

Step aside, internal tides: Supercomputer modeling improves satellite altimetry precision
Waves don't take place just on the ocean's surface. Underneath the crests and troughs that we can see from above are internal tides, which form when tidal flows collide with seamounts, continental slopes, and ridges on the seafloor......»»
Rural communities face greater risks of radon exposure compared to urban areas: Study
University of Calgary researchers have found a link between radon exposure in rural homes based on how close they are to drilled groundwater wells. The transdisciplinary team was investigating why homes in rural communities often have a much higher c.....»»
