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......»»
Ce-doped yttria transparent ceramic: A new ultraviolet-shielding material for extreme conditions
Ultraviolet (UV) radiation can break most of the chemical bonds in organic matter, and prolonged exposure to ultraviolet light can cause significant harm to humans and objects. In response, UV-shielding materials have been developed to fulfill variou.....»»
Hackers can now even use your PC’s HDMI cable to steal data
Hackers have found a new use for AI to get their hands on critical data using leaked electromagnetic radiation fro your HDMI cable......»»
Opinion: If we want to settle on other planets, we"ll have to use genome editing to alter human DNA
When considering human settlements on the moon, Mars and further afield, much attention is given to the travel times, food and radiation risk. We'll undoubtedly face a harsh environment in deep space and some thinkers have been pointing to genome edi.....»»
Studies find China-based emissions of three potent climate-warming greenhouse gases have spiked in past decade
When it comes to heating up the planet, not all greenhouse gases are created equal. They vary widely in their global warming potential (GWP), a measure of how much infrared thermal radiation a greenhouse gas would absorb over a given time frame once.....»»
NASA’s flagship mission to Europa has a problem: Vulnerability to radiation

Exploring bird breeding behavior and microbiomes in the radioactive Chornobyl Exclusion Zone
New research finds surprising differences in the diets and gut microbiomes of songbirds living in the radiation-contaminated areas of the Chornobyl Exclusion Zone, Ukraine. This study is also the first to examine the breeding behavior and early life.....»»
Researchers report new solid contact, ion-selective electrodes
A research team led by Prof. Huang Xingjiu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences constructed a highly stable solid contact calcium ion-selective electrode. They used synchrotron radiation technique to reveal.....»»
Honest dialogue is needed to help build consensus around solar radiation modification technology
Solar Radiation Modification (SRM) is a suite of possible technologies to counteract global warming by reflecting incoming solar radiation......»»
Researchers create the world"s strongest ionizing terahertz radiation
Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's most intense terahertz.....»»
Detecting "Hawking radiation" from black holes using today"s telescopes
In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from Europe has found that Hawking radiation should be obse.....»»
The Earth"s changing, irregular magnetic field is causing headaches for polar navigation
The Earth's liquid molten outer core, composed mostly of iron and nickel, exerts an electromagnetic field extending from the north and south pole that protects the planet from harmful solar particle radiation......»»
Researchers create new type of composite material for shielding against neutron and gamma radiation
Recently, Dr. Huo Zhipeng and his student Lu Yidong from Hefei Institutes of Physical Science of Chinese Academy of Sciences have created a new type of composite material for shielding against neutron and gamma radiation. They used micron plate Sm2O3.....»»
Researchers create new software for the new European-Japanese Earth observation satellite EarthCARE
Preparations for the launch of the new Earth observation satellite EarthCARE (Earth Cloud Aerosol and Radiation Explorer) at the end of May are in full swing. The joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Ag.....»»
Seeing the color of entangled photons in molecular systems
Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way.....»»
Why Earthlings are safe when huge solar storms strike our planet
When solar storms and coronal mass ejections hit Earth and create the Northern Lights, people are physically protected from radiation by Earth's magnetic field and atmosphere. From time to time, the sun discharges billions of tons of solar matt.....»»
Attosecond core-level spectroscopy reveals real-time molecular dynamics
Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxati.....»»
Natural sun protection for wood floors and furniture
To keep wood from aging prematurely, it's important to protect it effectively against ultraviolet (UV) radiation. At the same time, people want to retain the look and feel of natural wooden surfaces, but the transparent protective coatings that are c.....»»
Studies reveal new clues to how tardigrades can survive intense radiation
Radiation damages their DNA; they're just able to repair that damage very quickly. Enlarge / SEM Micrograph of a tardigrade, more commonly known as a "water bear" or "moss piglet." (credit: Cultura RM Exclusive/Gregory S. Paulson.....»»
Largest gamma-radiation burst ever recorded spills its secrets
Back in October of 2022, astronomers around the world were baffled and awed by the largest gamma-radiation burst we’ve ever recorded. The burst was so … The post Largest gamma-radiation burst ever recorded spills its secrets appeared first on.....»»
