This analysis of ice cores relies on the assumption that there is limited biological activity altering the environment in the snow during its transition into ice. Research reported in the Journal of the Royal Society Interface, which has directly observed microbial activity in Antarctic and Arctic snow, has revealed that the composition of these small samples of gas trapped in the ice may have been affected by bacteria that remain active in snow while it is being compressed into ice — a process that can last decades.

According to the new study, In humans, an anti-virus protein known as APOBEC3H was found to defend against cross-species transmission from chimpanzees of the virus that gave rise to HIV-1. Zeli Zhang et al., from Heinrich-Heine-Universität Düsseldorf present this finding in a new PLOS Pathogens study.
Surgery to remove a part of the brain to give relief to patients with epilepsy does not always result in complete seizure relief. However, Marina Vannucci and lead author Sharon Chiang from Rice University developed a method for integrating functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) scans to find visual biomarkers that distinguish patients with the greatest likelihood of benefit. The study was appeared in Frontiers in Neuroscience.
Researchers found a path for drug discovery to treat the condition, which causes the majority of secondary hypertension. This was experimented at Eunice Kennedy Shriver National Institute of Child Health and Human Development, part of the National Institutes of Health This study was published in JCI Insight.
Latest evidence was provided that Edixomed, a UK biotechnology company, has developed a revolutionary new technology for tackling the enormous public health challenge of antimicrobial resistance (AMR). The findings were presented at the recent Wounds UK conference and Eurobiofilms 2017 congress.
A small CA2 region in the hippocampus of the brain involved in the linking up of memory fragments to form social memory, according to the study led by the researchers at the Department of Physiology, Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine).
The scientists from Salk Institute have found a simpler way to develop heart cells from embryonic stem cells by turning off a single gene. The effort, published in the journal Genes & Development, offers scientists a streamlined method to arrive at functioning heart cells (cardiomyocytes) for both research and regenerative therapies.
The current system of blood banks in India is such that rural patients are deprived of timely access to an adequate volume of life-saving blood, adding to preventable mortality. On the basis of an academic framework for a blood transfusion system, an alternative approach in which rural practitioners utilize unbanked blood transfusions from a voluntary pool of pre-screened donors was described.
Researchers have obtained the first detailed image of the structure of a membrane pore that enables epithelial cells to absorb calcium. The findings could accelerate the development of drugs to correct abnormalities in calcium uptake, which have been linked to cancers of the breast, endometrium, prostate, and colon. This study is published in the online edition of Nature.
Gut health is a key area of modern health research, with intensive examination of communication between gut and brain deemed pivotal to solving complex health and wellbeing issues. Flinders University is leading the way with intensive gut research and analysis, through a series of multi-disciplinary collaborations that are exploring this complex issue from several angles.
The U.S. Environmental Protection Agency said it would seek input from state and local officials as it considers how to rework a 1991 rule meant to protect people from lead and copper contamination in drinking water. The agency invited state officials to give input on revising the Lead and Copper rule at a two-hour meeting on January 8 at the EPA's headquarters in Washington.
A new led by Nagoya University researchers provides the deeper knowledge of the role that thyroid hormones, the tissues that produce them, and the biochemical pathways on which they act have in driving seasonal reproduction in some mammals, and how this new information may help explain seasonal changes in metabolism and mood that affect humans.
The review article entitled "Seasonal Rhythms: The Role of Thyrotropin and Thyroid Hormones" is part of a special section on Japanese Research in the January issue of Thyroid, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers and the official journal of the American Thyroid Association (ATA).
