There is a strong association between an older person's view of how they are aging and how well they will physically recover after a fall. That is the finding of a new research study which is the first to suggest how important psychological factors may be in post-fall physical recovery. Falls in older adults are a major health concern because they can lead to high levels of physical disability and hospitalization, as well as affecting people's ability to live independently.

Keeping a human in the loop significantly enhances emotional engagement during online psychological interviews.

A serendipitous observation has led to a surprising discovery: a new class of nanostructured materials that can pull water from the air, collect it in pores and release it onto surfaces without the need for any external energy. The research describes a material that could open the door to new ways to collect water from the air in arid regions and devices that cool electronics or buildings using the power of evaporation.

Researchers found that the Wnt5a protein, secreted by inflammatory fibroblasts within cancerous tumors, inhibits angiogenesis and consequently promotes hypoxia within tumors. Hypoxic conditions help sustain the inflammatory fibroblasts, which also secrete the growth factor epiregulin, thereby promoting tumor growth. This newly proposed mechanism for tumor growth offers a promising new target for cancer therapies and possibly other conditions linked to inflammation, such as inflammatory bowel disease.

A study has found that implementing robust air pollution control measures could mean Southeast Asian countries prevent as many as 36,000 ozone-related premature deaths each year by 2050.

In nature, ecosystems are tightly linked through the flow of organisms, detritus, and nutrients across boundaries arbitrarily imagined by humans. These systems are deeply in tune with seasonal changes, fostering a harmonious ebb and flow of resources. Many of these connections remain poorly understood, especially the mechanisms responsible for maintaining biodiversity at the landscape level. One important example is the environmental drivers underlying variations in life-histories, or how organisms grow, survive, and reproduce in natural ecosystems. But as human activities ravage biodiversity on a global scale, elucidating the factors that cause variations in an organism's life-history is fundamental for understanding not only population persistence and adaptation to fluctuating environments, but also effective conservation and management.

How do organisms adapt to climate change? A new study reveals the complex interplay between genetic diversity and temperature tolerance evolution.

A research team has developed the world's first Pixel-Based Local Sound OLED technology. This breakthrough enables each pixel of an OLED display to simultaneously emit different sounds, essentially allowing the display to function as a multichannel speaker array. The team successfully demonstrated the technology on a 13-inch OLED panel, equivalent to those used in laptops and tablets.

New international research demonstrates global-scale patterns in how El Ni o-Southern Oscillation (ENSO) influences mangrove growth and degradation. Previously, impacts had only been documented at individual sites, such as a dramatic die-off in northern Australia in 2015 when more than 40 million mangrove trees perished along a 1,200-mile stretch of coastline.

The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA editing influences fungal antiviral responses. They identified two neighboring genes -- an RNA-editing enzyme (old) and a transcription factor (zao) -- that regulate virus-induced gene expression. Their findings show how the old-zao module controls both asymptomatic and symptomatic infections, providing new insight into conserved antiviral mechanisms in fungi.

As sea levels climb and weather grows more extreme, coastal regions everywhere are facing a creeping threat: salt. Salinization of freshwater and soils adversely affects 500 million people around the world, especially in low-lying river deltas. A new study sheds light on how rising oceans are pushing saltwater into freshwater rivers and underground water sources in the world's largest river mouth -- the Bengal Delta in Bangladesh.

Blue phosphorescent OLEDs can now last as long as the green phosphorescent OLEDs already in devices, researchers have demonstrated, paving the way for further improving the energy efficiency of OLED screens.

Researchers have developed a vascularized organoid model of hormone secreting cells in the pancreas. The advance promises to improve diabetes research and cell-based therapies.

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is a special form of helium in which the atom s two electrons are replaced by a single, much heavier muon.

Researchers developed a faster, more stable way to simulate the swirling electric fields inside industrial plasmas -- the kind used to make microchips and coat materials. The improved method could lead to better tools for chip manufacturing and fusion research.

Researchers have discovered a new 2D material, confirming decade-old prediction.

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists have now derived universal rules to enable the de novo design of optimal enzymes. As an example, they considered the enzymatic reaction of breaking a dimer into two monomer molecules. Considering the geometry of such an enzyme-substrate-complex, they identified three golden rules that should be considered to build a functional enzyme.

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud of ionized particles that briefly enveloped the moon and amplified its weak magnetic field.

A group of fossils of elasmosaurs -- some of the most famous in North America -- have just been formally identified as belonging to a 'very odd' new genus of the sea monster, unlike any previously known. This primitive 85-million-year-old, 12 meter-long, fiercely predatory marine reptile is unlike any elasmosaur known to-date and hunted its prey from above.

A new study uses metabolic profiling to uncover ancient knowledge systems behind therapeutic and psychoactive plant use in ancient Arabia.
