Powerful Enzyme that Tamps Down Inflammation Holds Promise for Protecting the Eyes in Diabetes, Premature Birth

Drs. Ruth and William Caldwell

An enzyme under study to treat certain cancers is also showing promise in reducing the significant vision damage that can result from diabetes and premature birth, scientists report.

Inflammation is considered a hallmark of cancer. It’s pervasive as well in both of these potentially blinding eye conditions, in which inadequate oxygen to the eyes prompts growth of new blood vessels to better deliver oxygen, but which instead often obstruct the vision pathway and become leaky, which causes swelling, further hindering vision.

Scientists at the Medical College of Georgia report in newly published studies in the journals Cell Death and Disease and Cells, increasing evidence that making more of the enzyme arginase 1, or A1, available helps alleviate these...

Healthy Aging Requires an Understanding of Personality Types

 Relationship between lifestyle factors and different cognitive categories. The figure is color coded based on similarity of covariate. In dark blue are the factors related to financial strain, in shades of orange are the factors that require greater levels of concentration, in shades of green are the factors that relate to physical exercise, in purple and light blue is age and level of education, and in shades of yellow is smoking and drinking.

New research shows that older adults may be better supported as they age when their personalities are considered — for example, are they more like orchids or dandelions?

Researchers from Simon Fraser University’s Circle Innovation examined the potential effects of lifestyle activities on the cognitive health of more than 3,500 adults aged 60...

Heat-Proof Chaotic Carbides could Revolutionize Aerospace Technology

Glowing orange tubes moving through light and air
The carbides could achieve improved communications and thermal regulation in technologies including satellites and hypersonic aircraft.

A group of scientists led by Duke University have engineered a new class of materials capable of producing tunable plasmonic properties while withstanding incredibly high temperatures.

Plasmonics is a technology that essentially traps the energy of light within groups of electrons oscillating together on a metallic surface. This creates a powerful electromagnetic field that interacts with incoming light, allowing devices to absorb, emit or otherwise control specific frequencies across much of the electromagnetic spectrum.

The new materials are hard enough to stir molten steel and can withstand temperatures above 7000F– about the same temperatures...

James Webb Space Telescope reveals new surprises on Galaxy Organic Molecules Near Black Holes

James Webb Space Telescope reveals new surprises on galaxy organic molecules near black holes
Maps of the central ∼6″ region of NGC 7469, which includes the AGN and the circumnuclear ring of star formation. Top-left panel: in color and black contours is the JWST/F770W PSF-subtracted image (which mainly traces the 7.7 μm PAH band). Black regions (s1, s2, s3, s4, s5, s6, and s7) correspond to selected circumnuclear zones of NGC 7469. Red and blue regions (o1, o2, o3, o4, o5, and o6) are in the outflow region. The green line represents the orientation of the nuclear molecular gas bar. The gray lines correspond to the approximate outflow region according to the [S IV]λ10.51 μm velocity map (see Appendix B). The white box represents the JWST/MRS ch1 FoV (3.2″ × 3.7″), which is practically identical to the Spitzer/IRS angular resolution...
