Aquatic and terrestrial cyanobacteria produce methane

open access: yesScience Advances, 2020
Cyanobacteria, the most ancient and abundant photoautotrophs on Earth, produce the greenhouse gas methane during photosynthesis. Evidence is accumulating to challenge the paradigm that biogenic methanogenesis, considered a strictly anaerobic process, is ...

Microbiomes Associated With Foods From Plant and Animal Sources

open access: yesFrontiers in Microbiology, 2018
Food microbiome composition impacts food safety and quality. The resident microbiota of many food products is influenced throughout the farm to fork continuum by farming practices, environmental factors, and food manufacturing and processing procedures ...

The reliability paradox: Why robust cognitive tasks do not produce reliable individual differences

open access: yesBehavior Research Methods, 2017
Individual differences in cognitive paradigms are increasingly employed to relate cognition to brain structure, chemistry, and function. However, such efforts are often unfruitful, even with the most well established tasks.

Assessment of Biological Soil Amendments of Animal Origin Use, Research Needs, and Extension Opportunities in Organic Production

open access: yesFrontiers in Sustainable Food Systems, 2019
The use of biological soil amendments of animal origin (BSAAOs) to improve soil fertility and quality plays an important role in organic agriculture in the U.S.

Prokaryotic viperins produce diverse antiviral molecules

open access: yesNature, 2020
Viperin is an interferon-induced cellular protein that is conserved in animals 1 . It has previously been shown to inhibit the replication of multiple viruses by producing the ribonucleotide 3′-deoxy-3′,4′-didehydro (ddh)-cytidine triphosphate (ddhCTP ...

Iron line afterglows: how to produce them [PDF]

open access: yes, 1999
We discuss how a powerful iron line emission can be produced if ~1-5 iron rich solar masses are concentrated in the close vicinity of the burst. Recombination, thermal and fluorescent reflection are discussed.

Defective HIV-1 proviruses produce viral proteins

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance In HIV-infected patients on combination antiretroviral therapy (cART), greater than 95% of proviruses in the peripheral blood are “defective.” Historically, these defective proviruses have been thought to be dead-end products with no real ...

Ambient Parameter Monitoring in Fresh Fruit and Vegetable Supply Chains Using Internet of Things-Enabled Sensor and Communication Technology

open access: yesFoods, 2022
Up to half of the global fruit and vegetable production is wasted or lost along the supply chain, causing wastage of resources and economic losses. Ambient parameters strongly influence quality and shelf life of fresh fruit and vegetables.

Do classical configurations produce Confinement?

open access: yes, 1996
We show that certain classical SU(2) pure gauge configurations give rise to a non-zero string tension. We then investigate cooled configurations generated by Monte Carlo simulations on the lattice and find similar properties.
