Spending time in nature is good for us. Studies have shown that contact with nature can lift our well-being by affecting  emotions, influencing  thoughts, reducing stress and improving physical health. Even brief exposure to nature can help. One well-known study found that hospital patients recovered faster if their room included a window view of a natural setting. Knowing more about nature’s effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Yet studies on the benefits of contact with nature have typically focused primarily ...

Language and music may share evolutionary functions. Both speech and song have features such as rhythm and pitch. But are similarities and differences between speech and song shared across cultures? To investigate this question, 75 researchers—speaking 55 languages—were recruited across Asia, Africa, the Americas, Europe and the Pacific. Among them were experts in ethnomusicology, music psychology, linguistics, and evolutionary biology. The researchers were asked to sing, perform instrumentals, ...

A new study has confirmed a long-held assumption: that orcas take just one breath between dives. The researchers used drone footage and biological data from tags suction-cupped to 11 northern and southern resident killer whales off the coast of B.C. to gather information on the animals’ habits. Whaley fun facts Published in PLOS ONE, the study found that residents spend most of their time making shallow dives, with the majority of dives less than one minute. The longest dive recorded was 8.5 minutes, for an adult male. “Killer whales are like sprinters who don’t have the marathon endurance of blue and humpback whales to make deep and prolonged dives,” ...

Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a study published May 15, 2024 in the open-access journal PLOS ONE by Sara Souther of Northern Arizona University, US, and colleagues. Recent research has detected declines in populations of pollinator species, sparking alarm from scientists and policymakers concerned about negative impacts on ecosystems and agriculture. These declines have been linked to various factors including climate change, habitat loss, and invasive species, but ...

Seventy-five researchers from 46 countries recorded themselves performing traditional music and speaking in their own languages in a novel experiment investigating cross-cultural differences and similarities. With rare exceptions, the rhythms of songs and instrumental melodies were slower than for speech, while the pitches were higher and more stable, according to the study published in Science Advances. Unique for the number of languages represented – 55 – and the diversity of the researchers, the study provides “strong evidence for cross-cultural regularities,” according to senior author Dr Patrick ...

A team of researchers at Delft University of Technology has developed a drone that flies autonomously using neuromorphic image processing and control based on the workings of animal brains.  Animal brains use less data and energy compared to current deep neural networks running on GPUs (graphic chips). Neuromorphic processors are therefore very suitable for small drones because they don’t need heavy and large hardware and batteries. The results are extraordinary: during flight the drone’s deep neural network  processes data up to 64 times faster and consumes three times less energy than when running on a GPU. Further developments of this technology may ...

Niels de Winter, affiliated with the Department of Earth Sciences at Vrije Universiteit Amsterdam and the AMGC research group at Vrije Universiteit Brussel, measured alongside colleagues from institutions such as the Institute for Natural Sciences in Brussels the chemical composition of fossil shells from Antwerp, Belgium. Those shells originate from molluscs such as oysters, cockles, and scallops found during the construction works of the Kieldrecht Lock. The molluscs lived lived during the Pliocene, approximately ...

The new funds will continue sponsoring San Francisco State’s Genentech ...

Payment for Ecosystem Services programs (PES) are important tools that governments around the world use to improve water quality, protect forests and wildlife habitat, and sequester carbon. Under these programs, landowners - usually farmers - are paid to use their land in ways that protect or restore the environment, such as replacing row crops with trees or grassy zones adjacent to waterways. Many PES program contracts last 5 to 20 years, but participant drop out rates have consistently risen over the years. A recent study by University of Maryland economists showed that PES programs ...

Researchers from Kaunas University of Technology (KTU), Lithuania, who contributed to the development of record-breaking solar cells a few years ago, expanded their invention. The self-assembled monolayers can now be applied not only in inverted but also in regular structure perovskite solar cells. Self-assembling molecules arrange themselves into a single-molecule-thick layer and in this case, they act as an electron-transporting layer in solar cells.  “The molecules that make up these monolayers, like a clever glue, ...

It’s one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It’s quite another to physically show it’s possible. That’s exactly what Harvard physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world’s longest fiber distance between two quantum memory nodes to date. Think of it as a simple, closed internet between point A and B, carrying a signal encoded not by classical ...

The baobab (Adansonia) is a genus of trees with eight extant (in existence currently) species and a long history of humans marveling at them. For as much admiration the baobabs get, there is an equal amount of mystery surrounding their origin. Genomic and ecological analyses recently done by a global research team led by Sino-Africa Joint Research Center, CAS (hosted by Wuhan Botanical Garden of the Chinese Academy of Sciences), suggest that Madagascar, is the origin from where all other baobab species hail. With a deeper understanding of the baobabs' genetics, researchers are hoping to uncover some clues on what ...

The iconic baobabs, also known as upside-down trees, or the tree of life, have much cultural significance, inspiring innumerable arts, folklore, and traditions. A research published in Nature, involving international collaboration between Wuhan Botanical Garden (China), Royal Botanic Gardens (Kew, UK), University of Antananarivo (Madagascar) and Queen Mary University of London (UK) reveal a remarkable example of species radiation in Madagascar followed by long distance dispersal to Africa and Australia. With speciation, an astonishing divergence of pollination mechanisms evolved, that exploit hawkmoths, bats and lemurs for ...

NEW YORK, NY — What makes the oldfield mouse steadfastly monogamous throughout its life while its closest rodent relatives are promiscuous? The answer may be a previously unknown hormone-generating cell, according to a new study published online today in Nature from scientists at Columbia's Zuckerman Institute. "The hormone from these cells was actually first discovered in humans many decades ago, but nobody really knew what it did," said Andrés Bendesky, MD, PhD, a principal investigator at Columbia's Zuckerman Institute. "We’ve discovered ...

The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago, suggests a new study led by UCL and University of Vigo researchers. In the early 20th century, dinosaurs were considered slow-moving, “cold-blooded” animals like modern-day reptiles, relying on heat from the sun to regulate their temperature. Newer discoveries indicate some dinosaur types were likely capable of generating their own body heat but when this adaptation occurred is unknown. The new study, published in the journal Current Biology, looked at ...

Semiconductors are the foundation of all modern electronics. Now, researchers at Linköping University, Sweden, have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study, published in the journal Nature, is a significant step towards future cheap and sustainable organic semiconductors. “We believe this method could significantly influence the way we dope organic semiconductors. All components are affordable, easily accessible, and potentially environmentally friendly, which is a prerequisite for future sustainable ...

Americans have gotten used to seeing their doctors and other health care providers using telehealth video visits in the past four years. But a new study reveals that what a doctor has behind them during a telehealth visit can make a difference in how the patient feels about them and their care.  Even if the doctor is miles away from their usual in-person clinic or exam room, they should make it look like they’re there, the study suggests. Even better: sitting in an office with their diplomas hanging ...

The high-performance temperature sensing materials including high sensitivity, fast response, wide detection range are scarce and needful. This research developed a ceramic-based temperature with attractive performance that can be applied in high-temperature environments ...

The general equilibrium framework of the CGE model widely used in cost-benefit analysis in the field of energy and environmental policy. Based on standard micro- and macroeconomic theories, the CGE model establishes quantitative connections between various sectors of the economy, enabling the examination of both direct and indirect effects resulting from exogenous changes in the economy, as well as their global impacts on the overall economy.   A team of energy economists by Yu Liu from Peking University in Beijing, China recently outlined the detailed content of their CGE model. This model is constructed based on the CGE model theory of the Australian Center ...

Perovskite solar cells, which use materials with the same crystal structure as perovskite, are lightweight, flexible, easy to manufacture, and inexpensive. They can be attached to many different surfaces and are a promising technology. However, current perovskite solar cells are not durable, and they tend to be inefficient. New research shows how additive engineering with a polymerized ionic liquid to the metal halide perovskite material can improve the solar cell’s function, helping to pave the way for the future wide adoption of perovskite solar ...

LOS ANGELES — For adults with acute lymphoblastic leukemia (ALL), a type of cancer that originates in the bone marrow, allogeneic stem cell transplantation (more commonly known as a bone marrow transplant) may be necessary for survival. But for Hispanic patients, finding an identically matched donor within their family or through the bone marrow donor registry can be challenging, with only a 30% chance of finding a matching relative and a 48% chance of identifying a matching bone marrow donor through the national donor registry. However, a new Keck Medicine of USC study in Leukemia ...
