Loggerhead turtles use geomagnetic field to navigate large distances

The loggerhead turtle can learn and remember the magnetic signature of an area and does a ‘turtle dance’ when in a location that they associate with food, a study in Nature reports. The research presents mechanisms of how migratory species navigate using the magnetic field of the Earth. Sea turtles are renowned for their long-distance migrations and … Read more

Stubble burning in Punjab, Haryana contributes only 14% of PM2.5 in Delhi-NCR: study

Based on field measurements, airmass trajectories, and particle dispersion and chemical transport model simulations, a study published in January 2025 has found that there is no linear correlation between stubble-burning events in Punjab and Haryana and fine particulate matter (PM2.5) concentration in Delhi-NCR. The study also underscores that crop residue burning in Punjab and Haryana contributes … Read more

How does Antarctica’s only native insect species survive extreme winter?

Flightless Antarctic midge (Belgica antarctica) is the only known insect native to Antarctica that is able to survive the extreme climate. Researchers have uncovered a part of the mystery of how the Antarctic midge copes with freezing temperatures. They found that the midge deals with the seasons during its two-year life cycle by undergoing quiescence … Read more
