Researchers shed new light on carboxysomes in key discovery that could boost photosynthesis
A research team led by the Hong Kong University of Science and Technology (HKUST) has discovered how carboxysomes—carbon-fixing structures found in some bacteria and algae—work. The breakthrough could help scientists redesign and repurpose the st.....»»
Rolling with the punches: How mantis shrimp defend against high-speed strikes
Mantis shrimp are small creatures known for their superlatives. Their eyes have 12 to 16 different color receptors versus our own three, and can detect the polarization of light. Their punches are famously fast, accelerating on par with a 22-caliber.....»»
Solid-state polymer heat pump gets rid of the heat itself
Polymer changes temperature, shape when charged, moving to where the heat needs to be. Enlarge (credit: Jorg Greuel) Heat pumps are the most energy-efficient way of controlling indoor temperature. By moving heat between.....»»

Webb presents best evidence to date for rocky exoplanet atmosphere
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system......»»
A nebula that extends its hand into space
The Gum Nebula is an emission nebula almost 1400 light-years away. It's home to an object known as "God's Hand" among the faithful. The rest of us call it CG 4......»»
Solar max is coming—the sun just released three X-class flares
The sun is increasing its intensity on schedule, continuing its approach to solar maximum. In just over a 24-hour period on May 5 and May 6, 2024, the sun released three X-class solar flares measuring at X1.3, X1.2, and X4.5. Solar flares can impact.....»»
Attackers may be using TunnelVision to snoop on users’ VPN traffic (CVE-2024-3661)
Researchers have brought to light a new attack method – dubbed TunnelVision and uniquely identified as CVE-2024-3661 – that can be used to intercept and snoop on VPN users’ traffic by attackers who are on the same local network. .....»»
Physicists reach atomic-scale telegraphy with light
In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, the unit of frequency.....»»
