How sleep deprivation can harm the brain

Sleep deprivation decreases the amount of a factor that protects neurons

11-Sep-2023 - Not only does a lack of sleep make you feel awful, research has shown it impairs the brain. What’s more, sleep loss over long periods can even increase risk for Alzheimer’s and other neurological diseases. Researchers want to understand how sleep deprivation causes this harm. In a new study in ...

Degrading modified proteins could treat Alzheimer’s, other ‘undruggable’ diseases

New technique specifically targets and breaks apart certain proteins — rather than just interfering with them

03-Mar-2023 - Certain diseases, including Alzheimer’s, are currently considered “undruggable” because traditional small molecule drugs can’t interfere with the proteins responsible for the illnesses. But a new technique that specifically targets and breaks apart certain proteins — rather than just interfering ...

Beer hops compounds could help protect against Alzheimer’s disease

09-Nov-2022 - Beer is one of the oldest and most popular beverages in the world, with some people loving and others hating the distinct, bitter taste of the hops used to flavor its many varieties. But an especially “hoppy” brew might have unique health benefits. Recent research published in ACS Chemical ...

Biofuels from the brewery?

Separating beer waste into proteins for foods, and fiber for biofuels

07-Apr-2021 - Home brewing enthusiasts and major manufacturers alike experience the same result of the beer-making process: mounds of leftover grain. Once all the flavor has been extracted from barley and other grains, what's left is a protein- and fiber-rich powder that is typically used in cattle feed or put ...

'Semi-synthetic' bacteria churn out unnatural proteins

19-Jul-2019 - Synthetic biologists seek to create new life with forms and functions not seen in nature. Although scientists are a long way from making a completely artificial life form, they have made semi-synthetic organisms that have an expanded genetic code, allowing them to produce never-before-seen ...

Paper-based device could bring medical testing to remote locales

25-Oct-2013 - In remote regions of the world where electricity is hard to come by and scientific instruments are even scarcer, conducting medical tests at a doctor's office or medical lab is rarely an option. Scientists are now reporting progress toward an inexpensive point-of-care, paper-based device to fill ...

A molecular 'superglue' based on flesh-eating bacteria

15-Apr-2013 - In a classic case of turning an enemy into a friend, scientists have engineered a protein from flesh-eating bacteria to act as a molecular "superglue" that promises to become a disease fighter. "We've turned the tables and put one kind of flesh-eating bacterium to good use," said Mark Howarth, ...
