These small plastic particles less than 5 mm in length have been found everywhere because of plastic pollution – from the Earth’s deep oceans to remote regions in Antarctica, and even the seafood we eat. But, are microplastics really harmful?</p> Thu, 18 May 2023 14:55:13 +0000 webfull 189719 at /channels /channels/channels/news/study-sheds-light-how-immune-system-protects-body-348205 <p>First <a href="https://doi.org/10.1016/j.cell.2022.12.038">study</a> of humans with a rare immunodeficiency reveals how the immune system protects the body against pathogens known to cause serious diseases, such as tuberculosis and COVID-19.

Directly or indirectly, this feeling has many wide-ranging consequences for our psychological well-being as well as our physical health, even our longevity,” the study states.</p> Wed, 17 Jun 2020 22:42:47 +0000 webfull 161441 at /channels /channels/channels/news/rewriting-our-understanding-gastric-tumours-288173 <p><span>The immune system can be an important ally in the fight against cancer.

Cohen, PhD, made a significant discovery on how HIV escapes the body’s antiviral responses. The team uncovered how an HIV viral protein known as Vpu tricks the immune system by using its own regulatory process to evade the host’s first line of defence. This breakthrough was published yesterday in the scientific journal PLoS Pathogens and will be presented at the upcoming IAS 2015 conference in Vancouver. The findings pave the way for future HIV prevention or cure strategies. Wed, 15 Jul 2015 20:19:46 +0000 webfull 111158 at /channels
