When Kevin Ryan and the other hardworking volunteers at Mossom Creek Hatchery in Port Moody, B.C. release young coho smolts into the ocean, they’re never quite certain how many will return as adults. Mossom releases between 5,000 and 10,000 coho smolts each year, and is one of the few hatcheries to release coho directly into the ocean, rather than into a river. Until now, no research had looked at the success of direct ocean releases of coho. UBC researchers used acoustic telemetry to tag and track coho on their journey. The results were revealing: ...

Thanks to the dizzying growth of cosmic observations and measurement tools and some new advancements (primarily the “discovery” of what we call dark matter and dark energy) all against the backdrop of General Relativity, the early 2000s were a time when nothing seemed capable of challenging the advancement of our knowledge about the cosmos, its origins, and its future evolution. Even though we were aware there was still much to uncover, the apparent agreement between our observations, calculations, and theoretical framework was indicating that our knowledge of the universe was set to grow significantly and without ...

A new DC-DC power converter is superior to previous designs and paves the way for more efficient, reliable and sustainable energy storage and conversion solutions. The Kobe University development can efficiently interface with a wide range of energy sources while enhancing system stability and simplicity at an unprecedented efficiency. Electric power comes in two kinds, AC (alternating current) and DC (direct current). Famously, the question over which kind should be used for national power grids, the “Current War” of the late 19th century, got settled in favor of AC and most power plants today produce ...

Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders. For cells to protect themselves from viral infections, a series of immune responses typically occur, including programmed cell death called apoptosis and interferon signaling. While apoptosis is a normal process, which occurs with or without the presence ...

A systemic review of the current body of research shows that investigators have inadequately addressed the intersection of aging, health disparities, and cancer outcomes among older adults. This is the conclusion of a new paper published in the Journal of the American Geriatrics Society, and led by Nikesha Gilmore, PhD, a member of Wilmot Cancer Institute at the University of Rochester. As the population of survivors of cancer 65 and older will likely double in size during the next two decades, the review reveals an urgent need for ...

Dietary treatment is more effective than medications in irritable bowel syndrome (IBS). These are the findings of a study conducted at the University of Gothenburg. With dietary adjustments, more than seven out of ten patients had significantly reduced symptoms. Irritable bowel syndrome (IBS) is a common diagnosis that causes abdominal pain, gas and abdominal bloating, diarrhea, and constipation, in various combinations and with varying degrees of severity. Treatment often consists of dietary advice such as eating small and frequent meals and avoiding excessive intake of food triggers such as coffee, alcohol and fizzy drinks. Patients may also be given medications to improve specific ...

The study, published today in Journal of Fluid Mechanics, reveals for the first time how noise is generated and propagated from these engines, technically known as boundary layer ingesting (BLI) ducted fans. BLI ducted fans are similar to the large engines found in modern airplanes but are partially embedded into the plane's main body instead of under the wings. As they ingest air from both the front and from the surface of the airframe, they don't have to work as hard to move the plane, so it burns ...

A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults. Scientists have sought to figure out how special power works in hopes of advancing medical treatments for human cardiac patients, but the great physiological differences between fish and mammals make such inquiries difficult. So University of Utah biologists, led by assistant professor Jamie Gagnon, tackled the problem ...

Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. Those are the findings of a new study conducted by Charité – Universitätsmedizin Berlin and published in the journal Science.* The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries could further the development of artificial neural networks. The neocortex, a critical structure for human intelligence, is less than five millimeters thick. There, in the outermost layer of the brain, 20 billion neurons process ...

Scientists Identify Airway Cells That Sense Aspirated Water and Acid Reflux  The new work by UCSF researchers could lead to interventions to prevent pneumonia or treat certain types of chronic cough.  When a mouthful of water goes down the wrong pipe – heading toward a healthy person’s lungs instead of their gut – they start coughing uncontrollably. That’s because their upper airway senses the water and quickly signals the brain. The same coughing reflex is set off in people with acid reflux, when acid from the stomach reaches the throat.  Now, UC San Francisco scientists have identified the rare type of cell responsible ...

The land under nearly half of China’s major cities is undergoing moderate to severe subsidence, affecting roughly one-third of the nation’s urban population, according to a systematic national-scale satellite assessment. The findings suggest that within the next century, 22 to 26% of China’s coastal land will have a relative elevation lower than sea level, putting hundreds of millions of people at elevated risk of flooding due to sea-level rise. Over the last several decades, China has experienced one of the most rapid and extensive urban expansions in human history. This massive wave of urbanization may be threatened ...

Drugs of abuse, like cocaine and opioids, alter neuronal signaling in the nucleus accumbens (NAc), hijacking a key brain reward system involved with the fulfillment of innate needs for survival, according to a new study in mice. The findings provide mechanistic insights into the intensification of drug-seeking behaviors in substance use disorders. Persistent drug use is accompanied by a profound reprioritization of motivations, skewing decision-making behaviors toward a myopic focus on drug use over other innate needs, like eating or drinking water, often ...

The energy density of supercapacitors – battery-like devices that can charge in seconds or a few minutes – can be improved by increasing the ‘messiness’ of their internal structure. Researchers led by the University of Cambridge used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure. Supercapacitors are a key technology for the energy transition and could be useful for certain forms of public transport, as well as for ...
