Gulf Stream System at its weakest in over a millennium

Never before in over 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has been as weak as in the last decades. Researchers compiled proxy data, reaching back hundreds of years to reconstruct the AMOC flow history. They found consistent evidence that its slowdown in the 20th century is unprecedented…

Novel pooled testing strategies can significantly better identify COVID-19 infections

A novel approach to pooled testing could help identify up to 20 times more COVID-19 infections per day than individual testing. Simple pooled designs could be implemented with minimal changes to current testing infrastructures in clinical and public health laboratories. Continue Reading at ScienceDaily.com Click Here.

Extreme melt on Antarctica’s George VI ice shelf

Antarctica’s northern George VI Ice Shelf experienced record melting during the 2019-2020 summer season compared to 31 previous summers of dramatically lower melt, a new study found. Using satellite observations that detect meltwater on top of the ice and within near-surface snow, the researchers found the most widespread melt of any season. Surface meltwater ponding…

Scientists begin building highly accurate digital twin of our planet

A digital twin of our planet is being designed to simulate Earth’s climate system reaching into the future. It is a tool to support policy-?makers in taking appropriate measures to better prepare for extreme events. Continue Reading at ScienceDaily.com Click Here. Press Release Distribution Service

How a single cell slime mold makes smart decisions without a central nervous system

Having a memory of past events enables us to take smarter decisions about the future. Researchers have now identified how the slime mold Physarum polycephalum saves memories – although it has no nervous system. Continue Reading at ScienceDaily.com Click Here. Press Release Distribution Service

The way a fish swims reveals a lot about its personality, say scientists

Personality has been described in all sorts of animal species, from ants to apes. Some individuals are shy and sedentary, while others are bold and active. Now a new study has revealed that the way a fish swims tells us a lot about its personality. Continue Reading at ScienceDaily.com Click Here. Press Release Distribution Service

‘Missing ice problem’ finally solved

During glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the thickness of the glaciers. Continue Reading at ScienceDaily.com Click Here.

Attachable skin monitors that wick the sweat away?

A new preparation technique fabricates thin, silicone-based patches that rapidly wick water away from the skin. The technique could reduce the redness and itching caused by wearable biosensors that trap sweat beneath them. Continue Reading at ScienceDaily.com Click Here. Press Release Distribution Service

New method to track genetic diversity of salmon, trout

Scientists have demonstrated that DNA extracted from water samples from rivers across Oregon and Northern California can be used to estimate genetic diversity of Pacific salmon and trout. Continue Reading at ScienceDaily.com Click Here. Press Release Distribution Service

Researchers ‘cautiously optimistic’ about desert bighorn sheep recovery in Mojave Desert

Desert bighorn sheep in the Mojave National Preserve in California and surrounding areas appear to be more resilient than previously thought to a respiratory disease that killed dozens of them and sickened many more in 2013, a new study has found.

Mitochondrial function can play significant part in serious disease

Disorders of the cells’ energy supply can cause a number of serious diseases, but also seem to be connected to ageing. More research is needed on mitochondrial function to find future treatments. A new study shows how an important molecule inside the mitochondria affects their function in mice and fruit flies. The study adds valuable…

A speed limit also applies in the quantum world

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists have now shown what the speed limit is for complex quantum operations. The results are important for the realization of quantum computers, among other things. Continue Reading at ScienceDaily.com Click Here. Press Release Distribution Service

Direct cloning method CAPTUREs novel microbial natural products

Microorganisms possess natural product biosynthetic gene clusters (BGCs) that may harbor unique bioactivities for use in drug development and agricultural applications. However, many uncharacterized microbial BGCs remain inaccessible. Researchers previously demonstrated a technique using transcription factor decoys to activate large, silent BGCs in bacteria to aid in natural product discovery.

The hidden dance of roots revealed

New time-lapse videos capture something that’s too slow for our eyes to see: the growing tips of plant roots make corkscrew-like motions, waggling and winding in a helical path as they burrow into the soil. By using time-lapse footage, along with a root-like robot to test ideas, researchers have gained new insights into how and…

Animal evolution: glimpses of ancient environments

Real-time dialogue with a dreaming person is possible

Dreams take us to what feels like a different reality. They also happen while we’re fast asleep. So, you might not expect that a person in the midst of a vivid dream would be able to perceive questions and provide answers to them. But a new study shows that, in fact, they can. Continue Reading…
