Deforestation in Brazil's Atlantic Forest is forcing mosquitoes to feed on humans more frequently, a new study reveals. This shift significantly elevates the risk of diseases like dengue and Zika for communities near forest edges. Scientists warn this behavioural change in mosquitoes is a critical, often unseen, consequence of habitat loss, impacting public health long before outbreaks occur.

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's motion. He showed that space and time are intertwined into a single fabric called spacetime, which is curved by mass, explaining gravity as geometry. This fundamental shift altered our understanding of the universe's dynamic nature.

Scientists achieved a genetic breakthrough by removing an extra human chromosome using gene-editing technology. This landmark study successfully deleted the surplus chromosome 21 responsible for Down syndrome in laboratory cells. Gene activity patterns in these edited cells closely resembled normal cells. This marks the first time a chromosomal condition has been corrected at its root.

Scientists are now tracking falling satellites by listening to Earth's vibrations. Powerful shockwaves from re-entering space debris are detected by earthquake-monitoring instruments, allowing for near real-time reconstruction of flight paths and landing zones. This seismic method offers a crucial new way to understand where debris lands, complementing existing tracking systems.

Paralysed individuals are now playing video games using only their thoughts, thanks to Neuralink's brain-computer interface. This groundbreaking technology, implanted in patients with severe paralysis, translates neural signals into digital commands, restoring interaction and independence. Early trials show patients navigating the web and engaging in fast-paced games, marking a significant step towards regaining control and connection.

Clips of thin, whistling tones are going viral on social media, startling listeners who suddenly “hear” hidden words. The sound itself doesn’t change; once listeners know the sentence, their brains impose meaning, transforming whistles into intelligible speech. Known as sine-wave speech (SWS), the phenomenon shows how perception, expectation, and auditory priming shape what we hear, not secret messages or conspiracies.
