Study shows toxic effects of oil dispersant on oysters following deepwater horizon spill



Posted: 13 Sep 2018 01:00 PM PDT


A new study finds that oysters likely suffered toxic effects from the oil dispersant Corexit® 9500 when it was used to clean up the 2010 Deepwater Horizon oil spill. Researchers determined this by comparing the low levels of toxicity of oil, the dispersant and a mixture of the two on Eastern oysters.


Cancer drug and antidepressants provide clues for treating brain-eating amoeba infections



Posted: 13 Sep 2018 11:33 AM PDT


Researchers have now identified three new molecular drug targets in Naegleria fowleri and a number of drugs that are able to inhibit the amoeba's growth in a laboratory dish. Several of these drugs are already approved by the US Food and Drug Administration for other uses, such as antifungal agents, the breast cancer drug tamoxifen and antidepressant Prozac.


New genetics tool helps answer evolutionary questions

Developing cutting-edge statistical tools that can handle these massive new datasets is a piece of the research puzzle, and new research has just added a new tool for the modern genomic toolbox.


Scientists design new metabolic technology to open scientific data for everyone



Posted: 13 Sep 2018 11:33 AM PDT


XCMS-MRM and METLIN-MRM represent a cloud-based analysis platform that allows scientists to quantify molecules from biological samples and make their results publicly available.


Famous theory of the living Earth upgraded to 'Gaia 2.0'



Posted: 13 Sep 2018 11:20 AM PDT


A new twist has been given to the 'Gaia' theory that aims to explain why conditions on Earth have remained stable enough for life to evolve over billions of years.


A very special protein synthesis machinery



Posted: 13 Sep 2018 11:20 AM PDT


Sleeping sickness-causing parasites contain an unusual protein synthesis machinery. A team of researchers has resolved its very special structure for the first time.


High-resolution genomic map gives scientists unprecedented view of brain development



Posted: 13 Sep 2018 11:20 AM PDT


Researchers have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth. The analysis of thousands of brain cells isolated from mice offers researchers a high-resolution map that enables scientists to view the detailed genomic changes cells undergo as the cerebellum wires its neural circuitry.


Blazes of light reveal how plants signal danger long distances

Botoniest reveal reveal how glutamate, an abundant neurotransmitter in animals, activates a wave of calcium when a plant is wounded -- the best look yet at the communication systems within plants that are normally hidden from view.


Weather forecasting sheds light on where and when birds will fly



Posted: 13 Sep 2018 11:20 AM PDT


September is the peak of autumn bird migration, and billions of birds are winging their way south. Using a combination of artificial intelligence and weather forecasting can help scientists to predict the movements of millions of birds and support their conservation goals, according to new research.


Novel flying robot mimics rapid insect flight



Posted: 13 Sep 2018 11:19 AM PDT


A novel insect-inspired flying robot, developed by TU Delft researchers from the Micro Air Vehicle Laboratory (MAVLab), is presented in Science. Experiments with this first autonomous, free-flying and agile flapping-wing robot -- carried out in collaboration with Wageningen University & Research - improved our understanding of how fruit flies control aggressive escape maneuvers. Apart from its further potential in insect flight research, the robot's exceptional flight qualities open up new drone applications.


How a virus destabilizes the genome



Posted: 13 Sep 2018 11:19 AM PDT


New insights into how Kaposi's sarcoma-associated herpesvirus induces genome instability and promotes cell proliferation could lead to the development of novel antiviral therapies for KSHV-associated cancers.


How the immune system protects against Zika-induced neurological symptoms



Posted: 13 Sep 2018 11:19 AM PDT


A type of immune cell that produces a protein called CD4 plays an important role in protecting mice infected with the Zika virus against severe neurological disease, according to a new study.


Scientists use bear saliva to rapidly test for antibiotics



Posted: 13 Sep 2018 05:21 AM PDT


A team of scientists has discovered a technology that rapidly assesses potentially lifesaving antibiotics by using bacteria in saliva from an East Siberian brown bear.


Rare antibodies show scientists how to neutralize the many types of Ebola



Posted: 12 Sep 2018 05:24 PM PDT


Two new studies are bringing Ebola virus's weaknesses into the spotlight, showing for the first time exactly how human and mouse antibodies can bind to the virus and stop infection -- not only for Ebola virus, but for other closely related pathogens as well.
