Think it's hot now? The next five years will smash records, UN says
Global temperatures are set to repeatedly breach the 1.5°C safety threshold over the next five years, with Earth's hottest-year record expected to fall in the process, according to new UN climate projections. The findings mark a stark escalation from previous forecasts, signaling that dangerous warming is no longer a distant prospect but an imminent reality. For policymakers and businesses alike, the window for meaningful climate action is narrowing fast.

Cobalt honeycombs open a new path to quantum computing
Researchers have developed cobalt-based honeycomb structures as a promising new material for quantum computing, potentially replacing rare and costly metals like ruthenium and iridium. Cobalt is far more abundant and affordable, removing a significant barrier to scaling quantum technology. The finding could accelerate development of quantum hardware by making high-performance materials more accessible.

Scientists thought brain inflammation was driving long COVID but the scans told a different story
A major assumption about long COVID may need rethinking. New brain imaging research found no evidence of widespread neuroinflammation in patients with prolonged symptoms — a finding that challenges the prevailing hypothesis. Instead, the worst cases were linked to heightened activity in brain regions governing mood and emotion, pointing researchers toward a different biological explanation.

Arctic Ocean food chain is disrupted as a key tipping point has now been passed
A new study warns that the Arctic Ocean has crossed an irreversible tipping point, with the loss of sea ice exposing shallow waters to sunlight and triggering a chemical process that depletes nitrate, a nutrient critical to the entire marine food web. The cascade effect is already being felt across plankton, fish, seabirds, and marine mammals. Researchers say the shift is permanent, raising serious concerns about the long-term stability of Arctic ecosystems.
