Scientists have confirmed for the first time that radical changes of one volcano in southern Japan was the direct result of an erupting volcano 22 kilometers (13.7 miles) away. The observations from the two volcanos -- Aira caldera and Kirishima -- show that the two were connected through a common subterranean magma source in the months leading up to the 2011 eruption of Kirishima.
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.
New study reveals that a male fruit fly's decision to court or ignore a female stems from the convergence of motivation, perception and chance. The triad affects the balance of excitatory versus inhibitory signals in the brain to influence decision making. Findings may yield insights about addiction disorders, depression.
Latest calculation based on how subatomic muons interact with all known particles comes out just in time for comparison with precision measurements at new 'Muon g-2' experiment.
A study shows that the expression of PI3Kγ protein increases during infection by T. cruzi, an essential response in avoiding excessive inflammation and controlling parasitemia. Heart tissue analyses involving human patients who developed cardiopathy in the disease's chronic stage also provided results. The next challenge is to devise treatment for Chagas using molecules capable of modulating the cellular signaling pathway mediated by PI3Kγ.
Dr. LI Jiafang, from the Institute of Physics, Chinese Academy of Sciences, has recently formed an international team to apply kirigami techniques to advanced 3D nanofabrication.
Researchers at Tokyo Institute of Technology have developed a ruthenium-based perovskite catalyst that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The oxidation of sulfides is a commercially important process with broad applications ranging from chemicals production to environmental management.
Each memory is stored in a specific population of neurons called engram cells. When a memory is linked with another to generate an associative memory, two memory traces overlap. At the same time, individual memories maintain their own identities. Using two overlapping fear memories in mice, researchers show that synapse-specific plasticity guarantees both storage and identity of individual memories. They also show that memory traces no longer exist in the brain after complete retrograde amnesia.
Arranging into well-organized fibrillar aggregate, commonly known as amyloid fibril is an inherent property of any polypeptide chain. Amyloid fibrils are associated with a number of severe human pathologies like the Alzheimer's disease, Parkinson's disease, type 2 diabetes and many more. This review article includes the recent studies of identification and characterization of possible conformations of proteins which can act as aggregation precursor state (APS).
In this article, together with a review of the literature, we report two cases of imipenem-resistant Acinetobacter baumannii neonatal meningitis following ruptured myelomeningocele, treated with intravenous colistin with favorable results.
