Migratory songbirds climb to extreme altitudes during daytime

Posted: 07 May 2021 08:20 AM PDT

Great reed warblers normally migrate by night during its month-long migration from northern Europe to Sub-Saharan Africa. However, researchers have now discovered that during the few occasions when it continues to fly during daytime, it flies at extremely high altitudes (up to 6300 meters). One possible explanation for this unexpected and consistent behaviour could be that the birds want to avoid overheating.

Supernovae twins open up new possibilities for precision cosmology

Posted: 07 May 2021 06:39 AM PDT

Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions - one of their tried-and-true tools for studying the mysterious dark energy that is making the universe expand faster and faster.

Hologram experts can now create real-life images that move in the air

They may be tiny weapons, but a holography research group has figured out how to create lightsabers -- green for Yoda and red for Darth Vader, naturally -- with actual luminous beams rising from them.

Bacterial DNA can be read either forwards or backwards

Bacteria contain symmetry in their DNA signals that enable them to be read either forwards or backwards, according to new findings which challenge existing knowledge about gene transcription.

Quantum drum duet measured

Posted: 06 May 2021 11:20 AM PDT

Like conductors of a spooky symphony, researchers have 'entangled' two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks.

Engineers and biologists join forces to reveal how seals evolved to swim

Posted: 06 May 2021 11:20 AM PDT

Seals and sea lions are fast swimming ocean predators that use their flippers to literally fly through the water. But not all seals are the same: some swim with their front flippers while others propel themselves with their back feet.

Laser pulses with record-breaking intensity

Posted: 06 May 2021 07:54 AM PDT

Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using a petawatt laser. It took more than a decade to reach this laser intensity. These ultrahigh intensity light pulses will enable exploration of complex interactions between light and matter in ways not possible before.
