Published Coffee plantations limit birds' diets


A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
Published Inbreeding contributes to decline of endangered killer whales


The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.
Published Unraveling whale entanglement risk factors off Oregon Coast


New research is beginning to unravel the times of year and locations where whales are at greatest danger of entanglement in fishing gear on the Oregon Coast.
Published Nanotechnology could treat lymphedema


When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Researchers have now developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach.
Published Mind-control robots a reality?


Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published Parasites alter likelihood of fish being caught by anglers


Parasitic infections in salmonid fish can increase or decrease their vulnerability to angling, depending on their body condition.
Published Hummingbirds use torpor in varying ways to survive cold temps


Hummingbirds use the hibernation-like state of torpor in varying ways, depending on their physical condition and what is happening in their environment, according to new research.
Published New eyes discovered in trilobites


Researchers have detected previously overlooked eyes whose form and function could help to improve the evolutionary classification of archaic arthropods.
Published Noise harming ocean invertebrates and ecosystems


Noise from human activities is harming ocean invertebrates and ecosystems, new research shows.
Published Mountain forests are being lost at an accelerating rate, putting biodiversity at risk


More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.
Published How fishermen benefit from reversing evolution of cod


Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.
Published Humans are altering the diet of Tasmanian devils, which may accelerate their decline


New research shows how human-modified landscapes affect the diets of these marsupial scavengers.
Published Humans bite back by deactivating mosquito sperm


New research makes it likely that proteins responsible for activating mosquito sperm can be shut down, preventing them from swimming to or fertilizing eggs.
Published Compressive stress shapes the symmetry of Arabidopsis root vascular tissue


A cytokinin-mediated, proliferation-based mechanism is involved in the generation and maintenance of cell-type specific tissue boundaries during vascular development in Arabidopsis roots. Specifically, the HANABA-TARANU transcription factor forms a feed-forward loop to cytokinin signaling, which in turn regulates the position and frequency of cell proliferation of proto-vascular cells such that mechanical stress of the surrounding tissues guides growth in an apical-oriented manor, maintaining cell patterning throughout the tissue section.
Published Major advance in super-resolution fluorescence microscopy


Pushing the MINFLUX technique to higher spatial and temporal precision allows protein dynamics to be observed under physiological conditions.
Published Characterizing abnormal neural networks in dogs with anxiety


Researchers report abnormalities in functional neural networks of dogs diagnosed with anxiety. The study shows that compared with healthy dogs, those with anxiety exhibit stronger connections between the amygdala and other regions of the anxiety network. The findings might also help reveal how functional connections between anxiety-related regions of the brain are altered in cases of human anxiety disorders.
Published Mild fever helps clear infections faster, new study suggests


It may be better to let a mild fever run its course instead of automatically reaching for medication, new research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down naturally without medication. The health advantages of natural fever to humans still have to be confirmed through research, but the researchers say because the mechanisms driving and sustaining fever are shared among animals, it is reasonable to expect similar benefits are going to happen in humans.
Published Researchers control the degree of twist in nanostructured particles


Micron-sized 'bow ties,' self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team has shown.
Published Bird flu associated with hundreds of seal deaths in New England in 2022


Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
Published Game-changing high-performance semiconductor material could help slash heat emissions


Researchers have engineered a material with the potential to dramatically cut the amount of heat power plants release into the atmosphere.
