Radiation Is Everywhere. But It’s Not All Bad
Although radiation sounds scary, it isn’t necessarily harmful. Here’s what to know about the four types......»»
Testing shows some bacteria could survive under Mars conditions
An international team of radiation specialists, biologists and infectious disease experts has found four types of bacteria that are capable of surviving exposure to the hostile Mars environment. In their study, published in the journal Astrobiology,.....»»
Researchers develop thermal radiation controllable epsilon-near-zero material that can withstand extreme environments
Thermal radiation is electromagnetic radiation emitted by all objects with temperature and most representatively, there is the solar radiation spectrum that enters the Earth and causes the greenhouse effect......»»
Study explores the connection between nitrogen oxides control and SNA, ozone reduction
Sulfate-nitrate-ammonium (SNA) and other atmospheric aerosols play a significant role in influencing both atmospheric and environmental conditions. These aerosols impact climate directly through scattering and absorbing solar radiation, thus influenc.....»»
What the next solar maximum means for you
Much like the Earth, our sun is a dynamic body with a complex—and sometimes violent—weather system. Solar storms eject highly energetic radiation that can impact our planet, forming strong auroras and disrupting power grids, electronics, and sate.....»»
Microwave detectors and multiplexing: Researchers help astronomers examine the early universe
Perched atop a high plateau in Chile's Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes devoted to studying the oldest light in the universe: radiation left over from the Big Bang......»»
Chilled-out tadpoles defy climate odds
University of Queensland researchers have discovered a previously unknown mechanism that allows tadpoles in cold environments to mitigate the detrimental effects of ultraviolet (UV) radiation......»»
This Doctor Helped Spare Women from Radical Mastectomy
Canadian radiation oncologist Vera Peters pioneered the use of lumpectomies and postoperative radiation to treat breast cancer patients......»»
A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular me.....»»
Juno makes its first ultra-close flyby of the volcano-covered moon Io
"The cumulative effect of all that radiation has begun to show." Enlarge / Juno flyby of Io on Dec. 30, 2023. (credit: NASA) On Saturday NASA's Juno spacecraft, which has been orbiting Jupiter for the better part of a d.....»»
Researchers reveal linkage between wildfire activity and abrupt climate events during the Holocene
As a major Earth system component, wildfire plays an important role in the Earth's terrestrial ecosystems and climate system, with significant impacts on the atmosphere, radiation effects, vegetation, surface properties, global biogeochemical cycles.....»»
Probing for THz radiation directly at the source
The search for and development of efficient terahertz (THz) sources is one of the major scientific goals of the 21st century. The THz region of the electromagnetic spectrum is composed of light frequencies in between the infrared and the microwave ba.....»»
Research finds marine bacteria, atmospheric rivers can contribute to formation of ice clouds
Understanding cloud formation in polar regions is essential to discern the influence of solar radiation on the polar ice caps. Existing numerical models, however, struggle to replicate ice clouds accurately. Now, using real-world observations and cli.....»»
A possible way for early life on Earth to survive cosmic radiation
A team of biophysicists affiliated with several institutions in China has uncovered via experimentation the means by which early life might have been able to survive cosmic radiation. In their study, reported in the journal Nature Communications, the.....»»
Unlocking a climate puzzle: Study reveals hidden physics in quasi-linear temperature-radiation link
Curious about what drives Earth's climate sensitivity? A recent study in Advances in Atmospheric Sciences explores the complex links transforming the relationship between surface temperature and outgoing longwave radiation (OLR) from quartic to quasi.....»»
James Webb finds that rocky planets could form in extreme radiation environment
The James Webb Space Telescope investigated a disk that could be forming rocky planets, even though nearby massive stars are pumping out significant radiation......»»
Earth"s magnetic field protects life on Earth from radiation, but it can move, and the magnetic poles can even flip
The Earth's magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it moves......»»
Antarctic ozone hole getting deeper in mid-spring, research suggests
The hole in the Antarctic ozone layer has been getting deeper in mid-spring over the last two decades, despite a global ban on chemicals that deplete Earth's shield from deadly solar radiation, new research suggested Tuesday......»»
Data from Fermi Gamma-ray Space Telescope reveal gamma radiation pulses from Sagittarius A*
A pair of astrophysicists at Universidad Nacional Autonoma de Mexico has found, via study of data from the low-Earth orbiting Fermi Gamma-ray Space Telescope, regular gamma radiation pulses emanating from around the black hole (at the center of the M.....»»
Does spaceflight increase men"s risk of erectile dysfunction?
During missions into space, astronauts are exposed to high levels of galactic cosmic radiation and weightlessness. Simulation experiments in male rats indicated that these aspects of spaceflight can negatively affect vascular tissues relevant to erec.....»»
