Dallas drafted Caleb Downs in the 2026 NFL Draft, moving up to select the Ohio State safety who Dallas envisions can handle nickel, safety and cornerback duties and serve as a defensive multiplier to elevate his teammates.
The penny’s retirement has coin experts wondering if the nickel could be the next to go, since minting nickels costs far more than their face value (about 13.78 cents per coin in 2024 versus a 5-cent value, with roughly $85 million lost on nickels and $18 million on pennies that year). The U.S. Treasury has no formal plan to eliminate the nickel, and Americans still actively use nickels, but inflation and rising production costs keep the debate alive. Some lawmakers have floated rounding cash transactions to the nearest five cents as a potential workaround, which could shift how retailers handle small-change trades if the nickel disappears. Experts expect the nickel’s demise, if it happens, to be gradual—likely over ten to fifteen years—though it’s not imminent, and the coin could instead stay in circulation longer if policy or consumer behavior changes differently than anticipated.
NASA’s Perseverance rover found unusually high nickel levels (up to 1.1% by weight) in rocks from Neretva Vallis in Jezero crater, dating about 3 billion years, with nickel‑rich minerals in magnesium‑sulfate veins that resemble Earth’s pyrite. While this hints at a chemical environment that could support microbial processes, it does not prove life on Mars; the nickel’s origin is uncertain and requires further study.
Detroit Lions coach Dan Campbell and defensive coordinator Kelvin Sheppard are installing three new defensive packages this spring to make the base defense more versatile for passing downs after losing linebacker Alex Anzalone and nickel corner Amik Robertson. With Malcolm Rodriguez likely replacing Anzalone at WILL and additions like Christian Izien, Roger McCreary, and Avonte Maddox, Detroit aims to dial up more nickel and flexible alignments depending on the opponent and personnel, though Branch’s Achilles injury and future draft/free-agent moves will influence the final look.
Perseverance found nickel-rich rocks in Neretva Vallis (32 of 126 samples with nickel up to 1.1% by weight) often attached to iron-sulfide minerals and organic compounds, pointing to a water-influenced, reducing environment at Jezero Crater and making nickel potentially bioavailable for ancient Martian life, hinting at longer-lived habitable conditions.
The Titans released cornerback L'Jarius Sneed, and the Bengals are weighing a signing to bolster their secondary, potentially at nickel behind boundary corners Dax Hill and DJ Turner II; Sneed's experience in the slot and prior success with the Chiefs could make him a versatile, cap-friendly depth option.
NASA’s Hubble reobserved interstellar comet 3I/ATLAS during its close solar approach, allowing scientists to track nickel and iron emissions before and after perihelion with unprecedented precision. The study found the observed outer layers are sun-baked crust rather than pristine material, complicating direct measurements of its original metallicity, but SPHEREx data showing dust, water, and organics in the coma, along with the metal measurements, provide valuable insights into how heavy elements behave in other star systems and what this implies about planet formation.
New research suggests that the delayed rise of oxygen in Earth's atmosphere was controlled by the levels of nickel and urea, which initially limited cyanobacterial growth. As these compounds declined, cyanobacteria proliferated, releasing oxygen and triggering the Great Oxidation Event, a key step in making Earth habitable and providing insights for life beyond Earth.
A recent study of the interstellar object 3I/ATLAS revealed unusual chemical signatures, including the presence of nickel without iron and cyanide, which are atypical for natural comets and suggest possible technological origins. The object exhibits a steep increase in mass loss rates as it approaches the Sun, and its characteristics raise questions about its true nature, whether a natural comet or an alien artifact. Ongoing observations and analyses aim to clarify its origin and implications for extraterrestrial intelligence.
Aluminium and nickel prices surged following the imposition of sanctions on Russian supply, as concerns over disruptions to the global supply chain intensified. The sanctions, imposed in response to Russia's invasion of Ukraine, have raised fears of potential shortages and supply chain disruptions, leading to a sharp increase in commodity prices.
Aluminum and nickel prices soared on the London Metal Exchange following the imposition of US and UK sanctions prohibiting the delivery of Russian metal produced after midnight on Friday. The sanctions, designed to limit President Putin's military funding, have introduced significant uncertainties into the metals market, which has already been affected by Russia's invasion of Ukraine.
BHP, the world's largest mining company, has expressed doubts about the Australian government's support being enough to save the country's struggling nickel industry. Despite the government's efforts to aid the industry, BHP believes that additional measures may be necessary to ensure the sustainability of nickel mining in Australia.
The recent nickel price drop has revealed the lack of long-term planning by Western miners and governments, particularly in Australia, where taxpayer incentives are being offered as a belated response to the industry's challenges. However, these measures, such as royalty rebates and critical minerals funding, are seen as insufficient to address the significant cost disparities and may not be enough to reverse recent project closures. The situation highlights the need for better strategic planning and investment in the face of market volatility.
Glencore, a major mining company, has announced plans to sell its stake in the lossmaking nickel operations in New Caledonia, as part of its strategy to focus on core commodities. The company has been facing challenges in the nickel market, and the decision to divest from the New Caledonia operations reflects its efforts to streamline its portfolio and improve financial performance.
Researchers studying "teenage" galaxies, which formed in the first 3 billion years after the Big Bang, have made surprising discoveries. These galaxies contain heavy metal elements like nickel, which is rarely observed even in nearby galaxies. The galaxies also have higher temperatures, with hot pockets reaching over 13,350 degrees Celsius. The observations were conducted as part of the CECILIA Survey using the James Webb Space Telescope (JWST), aiming to understand the differences in galaxy evolution and the physics behind them. The study pays homage to Cecilia Payne-Gaposchkin, a pioneer in studying the chemical makeup of stars.
