Stories that are getting the most attention from our readers this week.
A 19-year-old faces charges for allegedly sparking New Jersey’s largest wildfire in nearly two decades, burning more than 15,000 acres so far. Investigators say he failed to fully extinguish a bonfire in the Pine Barrens, creating ideal conditions for a blaze fueled by wind and drought. With evacuation orders and widespread smoke alerts, firefighters rely on controlled burns to contain the threat, currently about halfway under control.
This issue of New Scientist knits together neurology, climate urgency and cosmic exploration to show how science is rewriting what we thought we knew. The cover feature “Rethinking Parkinson’s” argues the world’s fastest-growing neurological disorder may actually be two distinct diseases, each driven by separate cellular cascades. That insight reframes drug trials and could unlock tailored therapies for more than 10 million people worldwide—a population set to double by 2040.A five-part Polar Crisis special report delivers a sobering climate audit. Sea-ice extent in February hit its lowest point since satellite records began, dipping nearly 2 million square kilometres below the 1991–2020 average; models now link that loss to faltering global ocean currents. An economic deep dive warns that Arctic fossil deposits worth an estimated $90 billion face escalating cost overruns as thawing permafrost destabilises rigs and pipelines.In space news, “Strongest Evidence Yet of Alien Life” highlights James Webb Telescope data revealing dimethyl sulfide and phosphine—molecules produced almost exclusively by biology—around a Neptune-sized exoplanet. Researchers stress caution, noting a one-in-four chance of abiotic origins, but if confirmed it would mark the first remote biosignature ever detected.The philosophical essay “Solid, Liquid, Gas… Life?” proposes treating biology as a nonequilibrium phase of matter rather than a checklist of traits, a shift that could unify origins-of-life research with synthetic-cell engineering.Finally, the leader editorial “The Cold, Hard Truth” contends that chasing Arctic riches is a fool’s errand; spiralling insurance premiums and fragile logistics make a mockery of “new frontier” narratives. By spotlighting economic futility, it frames the climate section in moral as well as scientific terms. Together, these pieces paint a picture of science that is simultaneously humbling and empowering—forcing humanity to rethink its assumptions from the neuron to the North Pole.
