Making a meal of DNA in the seafloor

Posted: 14 Jun 2021 12:39 PM PDT

While best known as the code for genetic information, DNA is also a nutrient for specialized microbes. An international team of researchers has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source. One bacterium newly named by the team in fact is a true expert in degrading DNA.

Stents inspired by paper-cutting art can deliver drugs to the GI tract

Posted: 14 Jun 2021 10:12 AM PDT

Inspired by kirigami, the Japanese art of folding and cutting paper, engineers have designed a new type of stent that could be used to deliver drugs to the gastrointestinal tract, respiratory tract, or other tubular organs in the body.

Touchless technology could enable early detection and treatment of eye diseases that cause blindness

Posted: 14 Jun 2021 10:12 AM PDT

A new non-contact laser imaging system developed by engineering researchers, is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.

Potential new treatment target for Alzheimer's disease

Posted: 14 Jun 2021 10:12 AM PDT

A new study not only sheds light on how the APOE4 gene may cause some of the pathologies associated with Alzheimer's disease, but also suggests a new treatment target that might help people who carry the APOE4 gene in early and late stages of the disease. Researchers found that APOE4 is associated with the activation of an inflammatory protein that causes a breakdown in the blood-brain barrier which protects the brain.

A new model of Alzheimer's progression

Posted: 14 Jun 2021 10:12 AM PDT

Scientists explore how protein and signaling pathways change in patients with Alzheimer's disease. Their work creates a new model of disease progression, taking advantage of the heterogeneity that is inherent to human studies.

One step towards a daily-use deep UV light source for sterilization and disinfection

Posted: 14 Jun 2021 10:12 AM PDT

Researchers invented a more efficient device for doubling the frequency of incoming light by combining period reflectors inside a microcavity containing gallium nitride. This work may help in the construction of a deep UV light source with bactericidal effect that is both safe and practical.

Hair follicles heal blisters at personal cost

Posted: 14 Jun 2021 10:12 AM PDT

Easy, inexpensive, efficient: Researchers improve efficacy of new malaria drug

Posted: 14 Jun 2021 10:11 AM PDT

Artemisone is a promising substance in the fight against malaria. However, the active ingredient has yet to be used due its instability and because it is not easily absorbed by the body. A team has now pushed this a bit further. They have developed a very simple method for preparing the active ingredient that makes it easier to administer and store.

New glial cells discovered in the brain: Implications for brain repair

Posted: 14 Jun 2021 08:08 AM PDT

Neurons, nerve cells in the brain, are central players in brain function. However, a key role for glia, long considered support cells, is emerging. A research group has now discovered two new types of glial cells in the brain, by unleashing adult stem cells from their quiescent state. These new types of glia may play an important role in brain plasticity and repair.
