Germany's eROSITA Second Data Release Unveils Nearly Two Million X-ray Sources

On July 31, the German eROSITA consortium, led by the Max Planck Institute for Extraterrestrial Physics with participation from the University of Bonn, released its second major public dataset, eROSITA Data Release 2 (DR2). Built from the first three all-sky survey observations conducted by the eROSITA telescope aboard the Spectrum-Roentgen-Gamma (SRG) mission, this dataset is considered one of the most sensitive and comprehensive X-ray catalogs currently available to the public. The DR2 main catalog covers the 0.2–2.3 kiloelectron-volt (keV) band in the western hemisphere, containing nearly two million X-ray sources. Among these, over 1.9 million are point-like sources, primarily consisting of stars and actively accreting supermassive black holes; approximately 64,000 are extended sources,...

Additively Manufactured CrMoTaTiV Refractory Alloy Demonstrates Excellent Radiation Resistance

A materials study released on July 31 shows that a research team used laser powder directed energy deposition (LP-DED) technology to fabricate a novel Cr₁₀Mo₂₅Ta₂₅Ti₁₅V₂₅ refractory complex concentrated alloy and systematically evaluated its structural stability and mechanical properties under irradiation environments. The study targets the demand for high-temperature, high-irradiation structural materials in next-generation nuclear fission and fusion devices. In the study, samples were subjected to 3.5 MeV Fe²⁺ ion irradiation at the Ion Beam Materials Laboratory of Los Alamos National Laboratory in the United States, at irradiation temperatures of room temperature and 650°C, with local doses reaching approximately 1.8, 6, and 18 dpa. Microstructural analysis...

Wachtebeke Municipal Council Reintroduces Nuclear Power Plant Motion

The municipal council of Wachtebeke, Belgium, has once again seen a motion regarding the construction of a nuclear power plant in Paulina Polder, but this time, unlike before, the motion has gained the support of the far-right PVV party. Previously, the plan had been highly controversial, with local residents and environmental organizations strongly opposing the construction of a new nuclear power plant in this sensitive wetland area. They fear irreversible environmental impacts and question the necessity of building new nuclear plants during the energy transition. The introduction of this motion marks a further strengthening of opposition to the project. The PVV's support increases the likelihood of the motion passing and places greater pressure on local authorities. More...

Buried Cesium-137 Sealed Source Discovered by Texas Patrol Officer Near Roadside in Midland County

According to the Texas Department of Public Safety, a corporal with the department recently discovered a buried cesium-137 sealed radioactive source with an activity of 100 millicuries during a routine patrol near a roadway in Midland County. The incident resulted in no injuries or radiation contamination, and public safety was not threatened. On July 24 local time, the corporal, assigned to the department's Radioactive/Nuclear Threat Detection Section, was patrolling near South County Road 1210 when the vehicle-mounted radiation detection system activated. He then used other detection equipment to survey the surrounding area and traced the radiation signal to an underground location. To ensure safe disposal, he requested assistance from local, state, and federal...

IIT Develops Novel Nanomaterial for Efficient Recovery of Rare Earth and Uranium Resources

Researchers at the Indian Institute of Technology Roorkee have developed an acid-resistant magnetic nanocomposite capable of recovering uranium and rare earth elements from acidic leach solutions. The material consists of core active nanoparticles encapsulated in a protective silica layer, enabling efficient absorption and extraction of these valuable resources in complex acidic aqueous media. By synthesizing the silica shell using biocompatible reagents, the researchers not only enhanced the material's corrosion resistance but also made it safer and more environmentally friendly. This novel nanocomposite demonstrated exceptional performance in laboratory tests, recovering up to 370 grams of uranium and rare earth elements per kilogram of material. It can operate effectively not only under conditions such as natural groundwater...

Portuguese Parliament Advised to Assess Feasibility of Small Modular Reactors in the Country

On July 30, the Portuguese Parliament received a draft resolution recommending that the government adopt a pro-nuclear stance and conduct an assessment of the feasibility of using small modular reactors in the country. The draft emphasizes that, against the backdrop of the Russia-Ukraine conflict, successive wars in the Middle East, and the increasing fragility of international supply routes, energy security is no longer merely an economic or environmental issue but a core element of national sovereignty and strategic autonomy. Portugal should not ideologically exclude any low-carbon technology without objective research. The draft resolution points out that Portugal's current energy policy should balance supply security, economic competitiveness, consumer protection, and emission reduction goals, without preemptively rejecting any technology that could contribute to these...

Czech research team develops minimally invasive radiocarbon dating sampling method to aid dating of prehistoric rock art

A research team at the Czech Radiocarbon Laboratory (CRL) of the Nuclear Physics Institute of the Czech Academy of Sciences has developed a minimally invasive sampling method for dating carbon-based rock art, enabling the acquisition of materials needed for radiocarbon dating with virtually no damage to the rock art's appearance. After sampling, the outline of the rock art remains intact, with only a slight lightening of color in the sampled area. This method provides a new technical pathway for dating cave paintings of historical value. In the past, sampling of cave paintings was often strictly restricted for heritage conservation reasons, which also hindered related chronological determination efforts. The new method, through a gentler sampling approach, enhances the feasibility of dating carbon-based rock art while maximizing the preservation of its scientific and cultural value...
