The composition of sweat makes it a valuable diagnostic fluid. While it is mostly water, the small fraction containing electrolytes, metabolic byproducts, and chemical traces can reveal important information about a person's health. Today, commercial sweat-based sensors can already track dehydration, electrolyte loss, and more. One emerging application is the measurement of lactic acid in sweat. https://phys.org/news/2025-09-sugar-based-stabilizer-sensors-acidic.html Biochemistry Thu, 04 Sep 2025 09:54:04 EDT news676198441 Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark—they receive the products of photosynthesis, in particular sucrose (sugar), via the central transportation pathways of phloem. https://phys.org/news/2023-05-conveyed-signal-transmitting-sucrose-growth-roots.html Plants & Animals Tue, 30 May 2023 16:18:08 EDT news604682286 Plants, like humans, need to move sugar and other nutrients around their bodies to power their growth. But unlike humans, they do not have a heart to pump these vital nutrients. Instead, they use an amazing molecular pump mechanism that scientists have been studying for decades since its discovery more than 30 years ago. https://phys.org/news/2023-05-heart-pathogens.html Plants & Animals Wed, 17 May 2023 10:06:03 EDT news603536761 Researchers have begun to explore the underlying neural activity of eating behaviors in fruit flies to better understand the motives that drive feeding. https://phys.org/news/2023-03-fruit-flies-feast-pleasure-necessity.html Plants & Animals Tue, 07 Mar 2023 14:14:05 EST news597420805 Researchers at Nagoya University, Japan, have discovered a mechanism for the selective transportation of sugar and hormones in plants. The results also clarify that sugar transportation is necessary for male fertility in plants, which means pollen production. The findings were published in Proceedings of the National Academy of Sciences. https://phys.org/news/2022-12-unraveling-sugar-hormone-underlies-male.html Plants & Animals Tue, 27 Dec 2022 13:58:00 EST news591371872 Seagrasses play an important role in the climate. They are one of the most efficient sinks of carbon dioxide on Earth. A team of scientists from the Max Planck Institute for Marine Microbiology now reports that seagrasses release large amounts of sugar, largely in the form of sucrose, into their soils—worldwide more than 1 million tons of sucrose, enough for 32 billion cans of coke. Such high concentrations of sugar are surprising. Normally, microorganisms quickly consume any free sugars in their environment. The scientists found that seagrasses excrete phenolic compounds, and these deter most microorganisms from degrading the sucrose. This ensures that the sucrose remains buried underneath the meadows and cannot be converted into CO2 and returned to the ocean and atmosphere. They now describe their discovery in the journal Nature Ecology & Evolution. https://phys.org/news/2022-05-sweet-sea-mountains-sugar-seagrass.html Plants & Animals Mon, 02 May 2022 11:00:02 EDT news570703307 A team of researchers from Jagiellonian University and the Polish Academy of Sciences has found that honeybees fed a diet of alcohol-spiked food exhibit withdrawal symptoms when the alcohol is removed. In their paper published in the journal Biology Letters, the group describes experiments they conducted with honeybees and why they believe their findings are relevant to treatment of alcoholism in humans. https://phys.org/news/2021-06-honeybees-symptoms-weaned-alcohol.html Plants & Animals Wed, 16 Jun 2021 09:13:10 EDT news543053582 MSU-DOE Plant Research Laboratory (PRL) scientists have characterized a sucrose transporter protein found in common beans. The recently discovered protein could help us understand how beans tolerate hot temperatures. The transporter, called PvSUT1.1, is reported in the journal Plant Direct. https://phys.org/news/2020-08-newly-sugar-beans-tolerate-hot.html Plants & Animals Mon, 31 Aug 2020 15:31:10 EDT news518106666 When the papaya (Carica papaya) is ripening, its cell walls separate, making the tissue softer and more digestible. The cell contents become accessible and the sucrose in the fruit is more easily extracted. Sugarcane roots have recently been found to undergo a similar process. Their cell walls are modified during development to form gas-filled intercellular spaces in a type of tissue known as aerenchyma. https://phys.org/news/2019-04-advance-papaya-sugarcane.html Plants & Animals Wed, 03 Apr 2019 07:58:04 EDT news473497074 Yale scientists have discovered ways to blunt the craving for sugar—in fruit flies, at least. https://phys.org/news/2017-05-sugar-craving-crushedin-flies.html Cell & Microbiology Tue, 02 May 2017 07:31:44 EDT news412929094 Cooperative behaviour is widely observed in nature, but there remains the possibility that so-called 'cheaters' can exploit the system, taking without giving, with uncertain consequences for the social unit as a whole. A new study has found that a yeast colony dominated by non-producers ('cheaters') is more likely to face extinction than one consisting entirely of producers ('co-operators'). The findings, published April 30 in the open access journal PLOS Biology by Alvaro Sanchez and Jeff Gore from the Massachusetts Institute of Technology, are the results of the first laboratory demonstration of a full evolutionary-ecological feedback loop in a social microbial population. https://phys.org/news/2013-04-favors-extinction.html Evolution Tue, 30 Apr 2013 17:03:22 EDT news286560192 Scientists from Queen Mary, University of London have tracked bumblebees for the first time to see how they select the optimal route to collect nectar from multiple flowers and return to their nest. https://phys.org/news/2012-09-flight-bumblebee.html Plants & Animals Thu, 20 Sep 2012 12:23:01 EDT news267362572 Flying in the face of years of scientific belief, University of Illinois researchers have demonstrated that sugar doesn't melt, it decomposes. https://phys.org/news/2011-07-scientists-startling-truth-sugar.html Biochemistry Mon, 25 Jul 2011 11:59:11 EDT news230813934
