Alkaline hot springs, loaded with hydrogen and methane, emerge from the seafloor there.

Curiosity's rover cameras captured these yellow sulfur crystals after the rover accidentally cracked the host rock. Credit: NASA/JPL-Caltech/MSSS. The bright yellow sulfur crystals discovered by NASA's Curiosity rover have puzzled scientists because sulfur on Mars is normally associated with mineral formations, not elemental deposits.

The search for effective treatments for conditions including Parkinson's disease has been a long journey, with scientists exploring several intricate directions for many years. However, breakthroughs can emerge in the most ordinary places, pointing to nature's own pharmacies.

Stringing position reconstruction of Shualim seashells based on indentation location. Credit: Journal of Human Evolution (2026). DOI: 10.1016/j.jhevol.2026.103846 A remarkable discovery has been made in an Upper Paleolithic cave in the heart of Israel's rugged Negev Desert. Years after they were last worn, archaeologists dug up fragile seashell beads, still holding specks of ochre pigment and carefully pierced for stringing.

Illustration of the proposed mid-latitude dawn-sector current wedge during the 22 June 2015 geomagnetic storm. Researchers suggest this unusual ionospheric current system, linked to field-aligned currents, helped drive the slow, long-lasting geomagnetically induced currents recorded across New Zealand's South Island power grid.

Narcissism predicted lower anxiety and psychopathy predicted lower heart-rate reactivity. Credit: Yan Krukau Better immunity to stress is a superpower most of us would like to possess. Surprisingly, people with certain dark personality traits do have better protection against stress than most people. A recent study has found that people with the Dark Triad of personality traits—narcissism, psychopathy and Machiavellianism—respond to stress differently.

A simplified diagram illustrating "cannibalism order." As human-to-human consumption is repeated (A → B → C), the risk of transmitting infectious diseases increases, making cannibalism progressively less advantageous over time, according to the study's model.
