AMDEN - For decades, biomedical researchers have used mouse behavior to study pain, but some researchers have questioned the accuracy of the interpretations of how mice experience pain.
Fruit flies could one day provide new avenues to discover additional genes that contribute to a person's ability to learn and remember. Scientists at the University of Missouri are studying genes of fruit flies to explore why an individual fly can be a better learner than another. Many of those genes in fruit flies are similar to those found in people.
Small fishes play an important role in the marine food chain, providing food for larger fishes and water birds, but they are also caught for use as bait in both commercial and recreational fisheries. Over the past thirty years, a decline has been noted in some species of baitfish, leading scientists and resource managers to look more closely at the population dynamics of these important fish.
Blue sharks use large, swirling ocean currents, known as eddies, to fast-track their way down to feed in the ocean twilight zone--a layer of the ocean between 200 and 1000 meters deep containing the largest fish biomass on Earth, according to new research by the Woods Hole Oceanographic Institution (WHOI) and the Applied Physics Lab at the University of Washington (UW). Their findings were published on August 6, 2019, in the journal Proceedings of the National Academy of Sciences.
Fear can be measured in the brain and fearful life-threatening events can leave quantifiable long-lasting traces in the neural circuitry of the brain with enduring effects on behavior, as shown most clearly in post-traumatic stress disorder (PTSD).
Awareness is growing among scientists about the significance of pre-modern anthropogenic impacts prior to the Industrial Revolution on present-day patterns of biodiversity.
Under the watchful eyes of five high-speed cameras, a small, pale-blue bird named Gary waits for the signal to fly. Diana Chin, a graduate student at Stanford University and Gary's trainer, points her finger to a perch about 20 inches away. The catch here is that the perch is covered in Teflon, making it seemingly impossible to stably grasp.
When wildfires burn up forests, they don't just damage the trees. They destroy a key part of the global carbon cycle. Restoring those trees as quickly as possible could tip the scale in favor of mitigating severe climate change.
BATON ROUGE, La. -- Photosynthesis is the natural process plants and algae utilize to capture sunlight and fix carbon dioxide into energy-rich sugars that fuel growth, development, and in the case of crops, yield. Algae evolved specialized carbon dioxide concentrating mechanisms (CCM) to photosynthesize much more efficiently than plants.
Fire is a natural part of western forests, but the changing nature of fire in many parts of North America may pose challenges for birds. One bird, in particular, the Black-backed Woodpecker, specializes in using recently-burned forests in western North America, but like humans looking for a new family home, it's picky about exactly where it settles.
A hormone that is released in our brain when we fall in love also makes starfish turn their stomach inside out to feed, according to a new study from the Queen Mary University of London.
In the latest paper from the Geobacter Lab led by microbiologist Derek Lovley at the University of Massachusetts Amherst, he and colleagues report "a major advance" in the quest to develop electrically conductive protein nanowires in the bacterium Geobacter sulfurreducens for use as chemical and biological sensors. Details appear in the current issue of the American Chemical Society journal, ACS Synthetic Biology.
A research team led by Tufts University engineers has developed a 3D printed pill that samples bacteria found in the gut - known as the microbiome - as it passes through the gastrointestinal tract (GI). The ability to profile bacterial species inhabiting the gut could have important implications for conditions that affect and are affected by the intestinal microbiome, according to the researchers.
With the advent of consumer genetic testing, family secrets are becoming increasingly harder to keep under wraps. There are fewer and fewer skeletons remain safely locked in the closet. For encouraged by genetic companies' promise to shed light on dark moments in their histories, people have started spitting in a tube and sending away their DNA samples with boundless enthusiasm.
For centuries, people have done the hard work of mining useful minerals and metals from solid rock. Then, scientists learned how to harness the power of tiny microbes to do some of this labor. This process, called biomining, has become common on Earth.
