Sugar aversion hampers cockroach coupling
A new study from North Carolina State University shows the behavioral mechanism behind a sweet cockroach mating ritual that takes a bitter turn, resulting in rejected males......»»
How ESA helps South Africa share water fairly
Clustered at the edge of the Crocodile River in Mpumalanga Province, South Africa, stand thousands of farms and small holdings growing fresh fruit and sugar cane. Water to irrigate the crops is taken from the river, but this slows its flow rate and l.....»»
Cold molecular clouds as cosmic ray detectors
The ionization of the neutral gas in an interstellar molecular cloud plays a key role in the cloud's evolution, helping to regulate the heating and cooling processes, the chemistry and molecule formation, and coupling the gas to magnetic fields. Usua.....»»
Insulin rises before cells develop resistance, new diabetes research implies
Researchers have now presented results that may change our basic view of how type 2 diabetes occurs. Their study indicates that free fatty acids (FFAs) in the blood trigger insulin release even at a normal blood-sugar level, without an overt uncompen.....»»
Consumption of added sugar doubles fat production
Too much sugar is unhealthy - that we know, but it's not just down to the many calories. Even moderate amounts of added fructose and sucrose double the body's own fat production in the liver, researchers have shown. In the long term, this contributes.....»»
Helping stevia plants brave the cold
It's a fact—humans love sugar. For those of us who also like to watch our calories, sugar substitutes can help......»»
Researchers design a new highly-selective tool to study "undruggable" proteins through the sugars they depend on
Sugar has been called "evil," "toxic," and "poison." But the body needs sugars, too. Sugar molecules help cells recognize and fight viruses and bacteria, shuttle proteins from cell to cell, and make sure those proteins function. Too much or too littl.....»»
First the treats, then the tough stuff: A bacterial dinner plan for degrading algal blooms
Each spring in the North Sea, tiny algae grow in large numbers and release loads of sugar into the water—a feast for bacteria. Scientists from the Max Planck Institute for Marine Microbiology and the University of Greifswald have now investigated t.....»»
Time needed to sequence key molecules could be reduced from years to minutes
Using a nanopore, researchers have demonstrated the potential to reduce the time required for sequencing a glycosaminoglycan—a class of long chain-linked sugar molecules as important to our biology as DNA—from years to minutes......»»
Graph theory helps biologists study homeostasis
Healthy human bodies are good at regulating: Our temperatures remain around 98.6 degrees Fahrenheit, no matter how hot or cold the temperature around us. The sugar levels in our blood remain fairly constant, even when we down a glass of juice. We kee.....»»
Common bacteria modified to make designer sugar-based drug
Envisioning an animal-free drug supply, scientists have reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals......»»
Common bacteria modified to make designer sugar-based drug
Envisioning an animal-free drug supply, scientists have—for the first time—reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals. Published today in Nature Communications, the resear.....»»
Recycled cotton becomes new fabric
A lot of us recycle our old textiles, but few of us know that they are very difficult to re-use, and often end up in landfills anyway. Now, researchers at Lund University in Sweden have developed a method that converts cotton into sugar, that in turn.....»»
Novel catalysts improve efficiency of urea synthesis at ambient conditions
Converting both nitrogen (N2) and carbon dioxide (CO2) into value-added urea molecules via C-N coupling reaction is a promising method to solve the problem of excessive CO2 emissions......»»
Has a startup finally found one of food science’s holy grails with its healthy sugar substitute?
A little less than three years ago at the Computer Science Museum in Mountain View, Calif. the founders of a young company hailing from Cambridge, England addressed a crowd of celebrities, investors and entrepreneurs at Y Combinator’s August De.....»»
How SARS-CoV-2"s sugar-coated shield helps activate the virus
One thing that makes SARS-CoV-2, the virus that causes COVID-19, elusive to the immune system is that it is covered in sugars called glycans. Once SARS-CoV-2 infects someone's body, it becomes covered in that person's unique glycans, making it diffic.....»»
How SARS-CoV-2"s sugar-coated shield helps activate the virus
SARS-CoV-2, the virus that causes COVID-19, is coated with sugars called glycans, which help it evade the immune system. New research shows precisely how those sugars help the virus become activated and infectious and could help with vaccine and drug.....»»
Eat this, exercise now; new personalized software predicts and helps prevent blood sugar spikes
Not everyone has Type 2 diabetes, the disease that causes chronically high blood sugar levels, but many do. Around 9% of Americans are afflicted, and another 30% are at risk of developing it. Enter software by January AI, a four-year-old, subscriptio.....»»
Tax on sugary drinks unfairly targets Indigenous communities instead of improving health
"Sin taxes" are a tried, although not necessarily true, strategy for reducing harm connected to alcohol and tobacco. Calls for a tax on sugar-sweetened beverages are supported by a large body of evidence linking weight gain and Type 2 diabetes, to ex.....»»
To improve immunotherapy, researchers look to shift immune cells" access to sugar
New research suggests that a way to improve immunotherapy is by altering immune cells' access to sugar......»»
Prediabetes may be linked to worse brain health
Researchers analyzed data from the UK Biobank of 500,000 people aged 58 years on average, and found that people with higher than normal blood sugar levels were 42% more likely to experience cognitive decline over an average of four years, and were 54.....»»
