U.S. birds' Eastern, Western behavior patterns are polar opposites      (via sciencedaily.com) 

Scientists have established what could be considered a baseline map of annual avian functional and species diversity patterns in the U.S., finding that functional diversity patterns in the West, where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high.

On a warming planet, these Arctic geese rapidly found (and shared) a new migratory route      (via sciencedaily.com)     Original source 

As the planet warms, animals that breed in the Arctic are at particular risk. But a new study offers some encouraging news: in an apparent reaction to pressures along their former migratory route, a population of Arctic geese has rapidly adjusted, forming a new migration route and breeding location almost 1,000 kilometers from their original stomping grounds.

Deforestation in the tropics linked to a reduction in rainfall      (via sciencedaily.com) 

Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.

Quantum chemistry: Molecules caught tunneling      (via sciencedaily.com) 

Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.

The counting of nine billion trees could help manage climate credits and nature restoration      (via sciencedaily.com) 

Researchers have developed a method that has now mapped several billion trees and their carbon uptake in Africa's Sahel. In the future, the method could be used to monitor whether climate credit purchases have a positive effect on the number of trees and whether nature restoration is working.

Seabirds in the eye of the storm      (via sciencedaily.com) 

Hurricanes are becoming more intense due to the climate crisis. Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.

Blue whale foraging and reproduction are related to environmental conditions, study shows      (via sciencedaily.com)     Original source 

A new study of New Zealand blue whales' vocalizations indicates the whales are present year-round in the South Taranaki Bight and their behavior is influenced by environmental conditions in the region.

Better metric for prioritizing conservation of 'evolutionarily distinctive' species      (via sciencedaily.com) 

Researchers have published an updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness.

Jurassic shark: Shark from the Jurassic period was already highly evolved      (via sciencedaily.com) 

Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.

Australia's rarest bird of prey disappearing at alarming rate      (via sciencedaily.com) 

Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.

Breathing is going to get tougher      (via sciencedaily.com) 

Not all pollution comes from people. When global temperatures increase by 4 degrees Celsius, harmful plant emissions and dust will also increase by as much as 14 percent, according to new research.

Who are the first ancestors of present-day fish?      (via sciencedaily.com) 

What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the 'bony-tongues' or the 'eels', was the oldest. A study has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of 'Eloposteoglossocephala'. These results shed new light on the evolutionary history of fish.

Breakthrough in tin-vacancy centers for quantum network applications      (via sciencedaily.com) 

Tin-vacancy (Sn-V) centers in diamond have the potential to function as quantum nodes in quantum networks to transmit information. However, they pose limitations while showing optical properties to generate quantum entanglement. Researchers have now overcome this challenge by generating stable Sn-V centers that can produce photons with nearly identical frequencies and linewidths, paving the way for the advancement of Sn-V centers as a quantum-light matter interface.

Let there be (controlled) light      (via sciencedaily.com) 

In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states -- the so-called qubits -- are needed. Physicists have made a breakthrough in this effort: for the first time, they demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale.

The quantum twisting microscope: A new lens on quantum materials      (via sciencedaily.com) 

One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.
