A new study led by the University of Alicante (UA) and the Mediterranean Center for Environmental Studies (CEAM) analyzes the barriers separating scientific knowledge from environmental policy and its effective implementation. The research sets out how long it takes for scientific knowledge in ecology to reach environmental policies and the extent to which these policies subsequently translate into real-world outcomes.

Seven breached Planetary Boundaries continue to worsen as record ocean heat, droughts, floods, wildfires and extreme heat reveal an Earth system under strain, according to the latest Planetary Health Check. The annual update is authored by more than 60 scientists and produced by the Planetary Boundaries Science Lab at the Potsdam Institute for Climate Impact Research (PIK).

Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed a method that makes it possible to tune the frequency continuously.

Most people associate network performance with bandwidth, the amount of data that can be transferred per second. However, for many of today

Flies, mice and humans move in different ways because of their very different physiques, but their movements follow a common pattern

Crystals are usually thought of as rigid and brittle. Yet some molecular crystals can bend, jump, twist or even change shape when exposed to light. Understanding how tiny molecular movements inside an ordered crystal can produce such large visible motions is an important challenge for developing responsive materials that could eventually be used in actuators, sensors and other miniature devices.
