What's Happening in Science
The scientific community has been abuzz with recent discoveries that have significant implications for our understanding of the world and the universe. From the search for alien life to the impact of politics on federal contracts, here are five science stories you need to know.
The Search for Alien Life
Astronomers have narrowed down the search for life beyond Earth, identifying 45 rocky planets that may have the right conditions to support life. Using data from the European Space Agency's Gaia mission and NASA archives, researchers pinpointed worlds in the "habitable zone," where temperatures could allow liquid water to exist. Some of the most intriguing targets include nearby systems like TRAPPIST-1 and Proxima Centauri, offering tantalizing possibilities just dozens of light-years away.
Politics and Federal Contracts
A study published in Contemporary Economic Policy found that a company's political power can influence its success in obtaining federal contracts. The research analyzed data from S&P 1500 firms from 1999 to 2019 and revealed a positive relationship between a firm's political power and the number of contracts awarded, the size of the contracts, and the favorableness of the contract terms. Interestingly, engagement with local politicians was more useful to firms than engagement with national politicians when seeking to secure federal contracts.
Salamanders' Cold Sensitivity
Scientists have discovered that eight amino acids may explain salamanders' reduced cold sensitivity. Research published in FEBS Open Bio found that the transient receptor potential channel TRPM8 from salamanders that prefer cooler environments exhibits significantly diminished cold sensitivity compared with TRPM8 from frogs, which prefer warmer climates.
Mercury Levels in US Conservation Lands
A study published in The Journal of Wildlife Management found varying risks to species due to mercury pollution across the United States' National Wildlife Refuge System. Investigators analyzed mercury concentrations in 1,356 dragonfly larvae collected from 30 refuges located throughout the United States between 2021 and 2023. The study pinpoints waterbodies where mercury may threaten fish, wildlife, and human health.
The Collapse of Fish Migrations
The world's great fish migrations are collapsing, and that's a problem for millions of people. For centuries, fish migrations were as predictable as the seasons, with species like salmon, sturgeon, and giant catfish moving through rivers in vast numbers. However, these migrations are now under threat due to human activities such as damming, overfishing, and pollution.
