A Patch that could help Heal Broken Hearts

Cardiac Stromal Cell Patch Integrated with Engineered Microvessels Improves Recovery from Myocardial Infarction in Rats and Pigs

According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years. During a heart attack, or myocardial infarction (MI), a blocked artery and the resulting oxygen deprivation cause massive cardiac cell death, blood vessel impairment and inflammation. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a cardiac patch with tiny engineered blood vessels that improved recovery from MI in rats and pigs.

To effectively treat MI, lost heart muscle tissue must regenerate and new blood vessels must form to restore oxygen and nutrients to cells...

Soil-powered Fuel Cell promises Cheap, Sustainable Water Purification

Soil microbial fuel cells proven to be capable of creating energy to filter a person’s daily drinking water in Brazil test. Engineers at the University of Bath have shown that it’s possible to capture and use energy created by the natural reactions occurring in microorganisms within soil.

A team of chemical and electrical engineers has demonstrated the potential of cheap, simple ‘soil microbial fuel cells’ (SMFCs), buried in the earth to power an electrochemical reactor that purifies water.

The proof-of-concept design was demonstrated during field testing in North-East Brazil that took place in 2019 and showed that SMFCs can purify about three litres of water...

Astronomers discover Activity on Distant Planetary object

Panstarrs digital image
This new image of C/2014 OG392 (PANSTARRS) and its extensive coma combines many digital images into a single 7,700 second exposure. The dashed lines are star trails caused by the long exposure. Images captured October 14, 2020 using the Large Monolithic Imager on the 4.3 m Lowell Discovery Telescope.

Centaurs are minor planets believed to have originated in the Kuiper Belt in the outer solar system. They sometimes have comet-like features such as tails and comae—clouds of dust particles and gas—even though they orbit in a region between Jupiter and Neptune where it is too cold for water to readily sublimate, or transition, directly from a solid to a gas.

Only 18 active Centaurs have been discovered since 1927, and much about them is still poorly understood...

New insights into a Potential Target for Autoimmune Disease

Researchers from Penn teamed with colleagues to decipher the mechanism by which the protein DEL-1 leads to the generation of T cells expression FOXP3, which rein in inflammatory responses, such as those responsible for autoimmune disease. (Image: Courtesy of the Hajishengallis laboratory)

With insights into a molecular pathway that regulates the activity of Tregs, a type of T cell involved in immunosuppression, new research opens up possibly new avenues for treating inflammatory and autoimmune diseases.

Immune response is a balancing act: Too much can lead to inflammatory or autoimmune disease; too little could lead to a serious infection...
