Although sperm whales have not been driven to the brink of extinction as have some other whales, a new study has found a remarkable lack of diversity in the maternally inherited mitochondrial DNA within the species.
An innovative mechanical system that mimics the ventilation and blood flow in the chest cavity, housed in a specialized, sterile bioreactor, can support the growth of engineered whole lungs at human scale. Researchers designed this biomimetic environment to advance toward clinical application of whole lung regeneration for transplant using a patient's own cells, as described in BioResearch Open Access.
Discovering that the association between trees and two classes of underground mycorhizzal fungi can be detected from space is a huge leap forward in our ability to understand how forests change on a large scale because the fungi are indicators of forest nutrient uptake.
Researchers have shown how controlling cholesterol metabolism in pancreatic cancer cells reduces metastasis, pointing to a potential new treatment using drugs previously developed for atherosclerosis.
Researchers have shown for the first time how neurons in the SCN are connected to each other, shedding light on this vital area of the brain. Understanding this structure -- and how it responds to disruption -- is important for tackling illnesses like diabetes and posttraumatic stress disorder. The scientists have also found that disruption to these rhythms such as shifts in work schedules or blue light exposure at night can negatively impact overall health.
Researchers know that several proteins are involved in oyster shell formation, but how expression of these proteins is controlled is not well understood. Now investigators report that they have identified a protein called Pf-POU3F4 that promotes expression of two of these proteins, called Aspein and Prismalin-14.
With only three living individuals left on this planet, the northern white rhinoceros could be considered doomed for extinction. But now researchers have proposed a road map for preserving such endangered species through techniques that use stem cells and assisted reproduction technology.
In some animals, the same species can occur in two or more color types, or morphs. New research may help solve the mystery of how this can occur despite the pressures of evolution.
Scientists raise are raising awareness that long-term use of herbal remedies is no guarantee of their safety. Herbal remedies are an overlooked global hazard.
New research challenges the traditional view that baleen whales (Mysticetes) migrate between high-latitude feeding areas and low-latitude breeding areas.
