For decades, scientists have puzzled over the huge piles of mammoth bones scattered across Ice Age Europe, Asia and North America, unsure whether they were formed by natural processes or by humans. A new genetic study of 521 woolly mammoths has now supplied a striking clue: the sex of the animals themselves.

Since the Suez Canal opened more than 150 years ago, more than 120 fish species have migrated from the Red Sea into the Mediterranean. Researchers at Tel Aviv University have now created a statistical model that predicts which species are likely to make the move next, states a report by Phys Org.

In 1924, Arctic charr from Lake Geneva were introduced into Lake Allos. A hundred years later, scientists found that their descendants had developed different metabolic responses, even when raised under the same laboratory conditions.

The deep ocean has a way of turning ordinary events into unanswered questions. Far below the waves, sounds travel through water in ways that can make distant sources appear much closer or far stranger than they really are.

The spotted lanternfly has become one of the most destructive invasive insects in the United States, threatening vineyards, orchards and forests by feeding on the sap of hundreds of plant species. Finding its egg masses before they hatch is one of the most effective ways to slow its spread, but the eggs are well camouflaged and often overlooked by human searchers.

Imagine erasing almost every insect and small animal from an island, then watching nature rebuild itself from scratch. That was exactly what a team of ecologists did in the Florida Keys during one of the most influential ecological experiments ever conducted.

Over three summers, a doctoral researcher named Douglas Boyes spent more than 400 hours crouched beside English roadside hedges after dark, tapping branches with a stick and counting how many moth caterpillars fell onto a canvas tray below. Boyes, who split his time between Newcastle University and the UK Centre for Ecology and Hydrology, expected artificial street lighting to reduce caterpillar numbers by something like 10 per cent.

Sharvi Mahajan, a 14-year-old Indian-American student from California, has been named among the 10 finalists of the 2026 3M Young Scientist Challenge. Mahajan has developed a system to predict driver fatigue before it leads to accidents.

At first sight, Pando appears to be an ordinary forest of thousands of trembling aspen trees stretching across Utah's Fishlake National Forest. As reported by PBS, the reality beneath the ground is far more unusual.

Indian scientists at ICAR-NRRI, Cuttack, have shown that an artificial intelligence-designed enzyme, OpenCRISPR-1, can precisely edit rice DNA, matching the famous CRISPR-Cas9 across knockout, base editing and prime editing. The open-source platform, named POC1, could ease the patent burden on gene editing and speed India's push for climate-resilient, self-reliant crops.
