The global redistribution of marine and terrestrial species due to climate change is a major concern for conservation planners and resource managers. Now, new research using data from long term surveys of tropical fishes indicates that traditional studies of this range shift phenomenon largely ignore the sequential nature of species movement.
The study, published in Global Change Biology shows that what makes a species a successful "arriver" doesn't necessarily make you a successful "stayer".
Childhood obesity is a health threat that is becoming more and more common worldwide. It increases risk later on for a variety of life-threatening challenges, including type 2 diabetes, cancer, heart disease and even mental health problems.
Migraine is one of the most disabling disorders, affecting one in seven people and causing a tremendous social and economic burden. Several findings suggest that migraine is a disease affecting a large part of the central nervous system and characterized by a global dysfunction in sensory information processing and integration, which also occurs between migraine episodes (interictal period). For example, patients with migraine exhibit increased cortical responses to sensory stimuli during the interictal period.
Recreating extreme conditions in the lab, like those in the interior of planets and stars, is very complex and can only be achieved for fractions of a second. An international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now presented a new, very precise method of evaluating the behavior of mixtures of different elements under high pressure with the help of X-ray scattering.
Graduate student Ubadah Sabbagh placed a cold glass slide on the microscope. It was getting late and the lab was quiet. He adjusted a few settings, and traced along the optic tract before zooming in on the brain's thalamus. What he saw surprised him: two adjacent stripes of glowing spots, each dot denoting a cell body.
Researchers from Swansea University have developed a new environmentally friendly method for removing toxic chemicals from water.
A newly invented machine, called the Matrix Assembly Cluster Source (MACS), has been used to design a breakthrough water treatment method using a solvent-free approach.
The research, from The Institute for Innovative Materials, Processing and Numerical Technologies (IMPACT) within the College of Engineering at Swansea University, was funded by the EPSRC and led by Professor Richard Palmer.
Professor Richard Palmer explains:
Cardiovascular disease (also called heart disease) is one of the most common medical conditions older adults face. In nursing homes, almost half of all older adult residents have been diagnosed with problems affecting the heart and/or blood vessels.
ITHACA, N.Y. - When animal, insect or human embryos grow in a malnourished environment, their developing nervous systems get first pick of any available nutrients so that new neurons can be made.
In this process, called organ sparing, resources are preferentially delegated to the nervous system at the cost of less important organs or tissues.
A recent paper published in Frontiers in Neuroscience, outlines a pulse-pressure-induced pathway of cognitive decline that sheds light on why previous treatments for dementia may have failed and proposes promising new directions for the prevention and treatment of dementia.
A flame-retardant carbon-fiber-reinforced composite material has been developed. Korea Institute of Science and Technology (KIST) announced that a research team from its Institute of Advanced Composite Materials, headed by Dr. Yong chae Jung used plant-originated *tannic acid to develop a flame-retardant **carbon fiber-reinforced plastic (CFRP), and also presented a method for its eco-friendly recycling.
Volume 11 Issue 25 of @Oncotarget reported that Indoximod has shaped the understanding of the biology of IDO1 in the control of immune responses, though its mechanism of action has been poorly understood.
Indoximod can have a direct effect on T cells, increasing their proliferation as a result of mTOR reactivation.
Researchers at the University of Liverpool are making significant progress in the quest to develop new sulfur polymers that provide an environmentally friendly alternative to some traditional petrochemical based plastics.
University of Liverpool chemist and Royal Society Research Fellow, Dr Tom Hasell and his team, have published two papers which demonstrate practical and exciting developments for sulfur polymer technologies and application.
Dengue infections are rising, even as public health authorities are battling to contain the spread of the coronavirus. Dengue virus serotype 2 (DENV2) had previously been the predominant serotype but DENV3 has re-emerged in Singapore after almost three decades. This means the Singapore population has lower immunity to DENV3 and, consequently, a large proportion of the population is susceptible to DENV3 infection.
By preventing sugar uptake, researchers succeeded in increasing the cancer cells' sensitivity to chemotherapeutic treatment. The studies, led by researchers at Lund University in Sweden, were carried out on cancer cells in a lab environment. The results were recently published in the research journal Haematologica.
Mother's chronic prenatal psychological distress and elevated hair cortisol concentrations are associated with gut microbiota composition of the infant, according to a new publication from the FinnBrain research project of the University of Turku, Finland. The results help to better understand how prenatal stress can be connected to infant growth and development. The study has been published in the esteemed Psychoneuroendocrinology journal.
