Whales, sharks, butterflies and lotus leaves might together hold the secret to saving the shipping industry millions and help save the planet, according to a marine biologist at the University of Portsmouth, UK.
Instead of having more children, a grandmother may pass on her genes more successfully by using her cognitive abilities to directly or indirectly aid her existing children and grandchildren. Such an advantage could have driven the evolution of menopause in humans, according to new research published in PLOS Computational Biology.
Bornean orangutans living in forests impacted by human commerce seek areas of denser canopy enclosure, taller trees, and sections with trees of uniform height, according to new research. These orangutans are critically endangered, and despite intense conservation efforts, their numbers continue to decline. Additional habitat management strategies that account for their presence in forests affected by logging and other human activity are needed to ensure the species' survival.
Scientists team up to evaluate the tools used to probe the cancer genome.
A beetle is slower than a mouse, which is slower than a rabbit, which is slower than a cheetah... which is slower than an elephant? No! For small to medium-sized animals, larger also means faster, but for really large animals, when it comes to speed, everything goes downhill again. For the first time, researchers have described in the journal Nature Ecology and Evolution how this parabola-like relationship between body size and speed comes about.
Chronic obstructive pulmonary disease (COPD) can result in structural changes within the lungs over time. Scientists at the Helmholtz Zentrum München have now been able to show that these changes not only affect the organ itself, but also the bacteria that live in the lung. The results have been published in PLOS ONE.
One of the primary missions of neuroscience is to make connections between particular neurons in the brain and specific behaviors. Now a team of researchers has used computer-vision and machine-learning techniques in fruit flies to create behavior anatomy maps that will help us understand how specific brain circuits generate Drosophila aggression, wing extension, or grooming. The data are being published July 13 in the journal Cell as a resource for other investigators.
A research group at Uppsala University presents in PNAS a new, small-scale method that may become a smart shortcut for determining the 'bioavailability' of a pharmaceutical drug within cells. 'Finding out how a therapeutic drug affects the body means having to consider many different factors that can influence the cells' internal environment. Our method may be a way of substantially facilitating this stage.'
In a new study published in Nature, the same team shows in foundational proof-of-principle experiments that a new CRISPR system, as a first-of-its-kind approach, is able to encode information as complex as a digitized image of a human hand, reminiscent of some of the first paintings drawn on cave walls by early humans, and a sequence of one of the first motion pictures made ever, that of a galloping horse, in living cells.
Specialized beta cells in the pancreas release the hormone insulin to control our blood glucose levels, and failure of this mechanism is central to the development of type-2 diabetes. How much and when insulin is released depends on a complex system of messenger molecules and proteins that is not well understood.
