Scientists discover New T cells and Genes related to Immune Disorders

A newly developed method called ReapTEC allowed the discovery of thousands of active bidirectional enhancers. Further analysis of GWAS data revealed that various immune-mediated diseases, like multiple sclerosis and rheumatoid arthritis, are related to genetic variations within these enhancers.

Researchers led by Yasuhiro Murakawa at the RIKEN Center for Integrative Medical Sciences (IMS) and Kyoto University in Japan and IFOM ETS in Italy have discovered several rare types of helper T cells that are associated with immune disorders such as multiple sclerosis, rheumatoid arthritis, and even asthma...

Novel Smart Solar-Powered Freezer Truck Unveiled in Hong Kong

A research team led by Prof. Eric Cheng, Professor of the Department of Electrical and Electronic Engineering at PolyU has developed a novel freezer truck that supports a solar-powered freezer system and features vehicle-connected power storage and sharing technology.

The transport sector is a significant contributor to greenhouse gas emissions in Hong Kong, accounting for 19% of total emissions. Supporting the development of green transport can help reduce air pollutant emissions. The Hong Kong Polytechnic University (PolyU) is committed to promoting research into green technologies to support Hong Kong’s goal of reducing the City’s total carbon emissions from the 2005 level by half before 2035 and achieving carbon neutrality before 2050.

A research team led by Prof...

Repurposed Technology used to Probe New Regions of Mars’ Atmosphere

Using the repurposed equipment, a team including Imperial College London researchers have measured parts of the Martian atmosphere that were previously impossible to probe. This includes areas that can block radio signals if not properly accounted for—crucial for future Mars habitation missions.

The results of the first 83 measurements, analyzed by Imperial researchers and European Space Agency (ESA) colleagues across Europe, are published today in the journal Radio Science.

To achieve this, ExoMars’ Trace Gas Orbiter (TGO) teamed up with another ESA spacecraft orbiting the red planet: Mars Express (MEX). The two craft maintain a radio link, so that as one passes behind the planet, radio waves cut through the deeper layers of the Martian atmosphere.

Changes in the atmospher...

Ointment containing DNA Molecules can Combat Allergic Contact Dermatitis

Ointment containing DNA molecules can combat allergic contact dermatitis

Researchers at the University of Bonn have isolated a DNA molecule that is suitable for combating allergic contact dermatitis in mice. The aptamer binds to certain immune system messenger substances, rendering them ineffective. This even works if the active ingredient is applied to the skin in the form of an ointment.

The working groups involved hope that aptamer creams such as this could also be suitable for treating other skin conditions...
