A scientist behind a celebrated stream-restoration project in Porto resigned without warning after research found that most of the water crossing a revamped market was not flowing through a restored riverbed. The €34 million scheme (about $39 million) is now facing demands for a fresh scientific review and a halt to its environmental awards.
A Chinese film star’s announcement has drawn attention to an extraordinary finding in Guizhou: more than 1,100 tagged fish presumed lost from a research lake were detected at springs kilometres away. Scientists say the fish may have travelled through an underground limestone channel, connecting two basins that surface maps show as separate.
A recall of 18,600 air monitors has exposed a major blind spot in pollution readings used across parts of Indonesia. Independent tests found the devices understated dangerous haze peaks, sometimes classifying severe pollution as moderate.
A newly published Philippine study found that a takeaway tray marketed to break down in coastal water instead fractured into millions of plastic pieces. Its maker recalled 1.18 million trays on Saturday, warning shops to stop using them and offering refunds.
A new vent has opened on Arctic Norway’s Beerenberg volcano, while a scientist who resigned on Thursday says officials withheld the most severe eruption scenarios. The first ash plume is modest, but monitoring data show accelerating unrest and forecasters warn that a larger blast could disrupt hundreds of North Atlantic flights.
A buoy network meant to track Atlantic storms opened in Galway with its key west-coast feed missing and a live display showing calm seas. Researchers say the failure comes as Ireland faces a rising risk of exceptionally wet, damaging storms, with one forecast to approach next week.
A data-sharing law taking effect in eight countries has revealed that thousands of weather stations were quietly measuring more than researchers could see. The newly opened readings suggest farms and cities may be staying warm for hours longer than standard forecasts predict.
When a switching fault shut down a seed archive near Mexico’s Calakmul forest, botanist Qurratu Thalalla had hours to move thousands of samples. The rescue revealed that an old limestone chamber had quietly preserved hundreds of seed lots that staff thought were duplicates of poor quality.
A data-transparency law taking effect in the Netherlands has released readings that scientists say may point to rising magma beneath Germany’s Laacher See volcanic system. One researcher warns a dangerous escalation could come within days; officials say there is no confirmed eruption signal.
Volcanic ash rose 74 centimetres in a windless chamber, more than six times the previous laboratory benchmark, according to a study published in Italy on Friday. The researchers say electrical forces could lift ash inside real eruption clouds, complicating forecasts of where the particles will travel.
Egypt’s first release of detailed groundwater readings under a new public-data law has revealed salt levels reaching farther inland than at any time in a comparable 39-year record. Researchers warn the finding could reshape water planning for farms and towns across the Nile Delta, though the figures do not mean every local well is unsafe.
A lawsuit over missing flood warnings has brought to light the highest recorded flow at Athabasca Falls, where the river surged to 812 cubic metres per second in June. Hydrologists say the peak, confirmed in court evidence this week, points to a more dangerous mix of intense rain and rapid snowmelt in the Rockies.
