A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer's growth and spread, University of Illinois researchers report in a new study in mice. In mice with tumors of osteosarcoma - a bone cancer that is notoriously painful and difficult to treat -- endocannabinoids slowed the growth of tumors and blood vessels, inhibited the cancer cells from migrating and caused cancer cell death.
Scientists estimate there are only 84 remaining highly endangered Amur leopards (Panthera pardus orientalis) remaining in the wild across its current range along the southernmost border of Primorskii Province in Russia and Jilin Province of China.
Researchers accidentally observed tree shrews directly and actively consuming chili peppers, despite the deep geographic isolation between the animal and the food. To understand this tolerance for spicy food, they performed genomic and functional analyses on the tree shrew and its TRPV1.
University of Kansas scientists discovered that polyps have no qualms about treating a nonrelated individual like part of the family. This goes way beyond sharing meals or even a roof. Polyps of the marine hydrozoan Ectopleura larynx allow nonrelated individuals to fuse their bodies to the familial colony and share what is essentially skin and a stomach. The findings appeared yesterday in the journal Evolution Letters.
Biologists at the Ruhr-Universität Bochum characterized new, unknown photoreceptors from the bioluminescent flashlight fish Anomalops katoptron. The photoreceptors known as opsins allow the fish to detect light with a specific wavelength. As published on the July 11, 2018, in PLOS ONE the scientists found new opsin variants, which are specialized to detect low intensity blue light in the wavelength range of bioluminescent light emitted by the fish. The blue light can be used to influence the fish behavior.
Off the coast of Cyprus in the Mediterranean Sea, many fish farms have been moved into deeper waters -- and on the seabeds beneath their previous locations, the meadows are flourishing once again.
The inclusion of taxon-specific sensitivity to a shifting climate helps us understand species distributional responses to changes in climate.
A new mixture of cryoprotectives allows for an unprecedented high motility of frozen rhinoceros sperm after thawing, report scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Berlin, Germany. These new cryoprotectives can increase the prospects of utilizing assisted reproduction techniques for many endangered wildlife species. The study, based on three rhinoceros species, has now been published in the journal PLOS ONE.
Researchers at the University of Helsinki discovered and named a new endemic fish species in the Baltic Sea, the 'Baltic flounder,' Platichthys solemdali.
A study finds that chemicals used in flame retardants, plasticizers and other commercial products are broken down through the process of metabolism into other compounds. Researchers say not enough is known about the dangers posed by those compounds, known as metabolites.
