Semen Quality Threatened by Endocrine Disruptors
Scientists have established a link between poor semen quality in adult men and their mothers’ occupational exposure to endocrine disruptors during pregnancy.

Solving Nucleic Acid Synthesis Mystery May Help To Design New Antivirals
Scientists have solved the mystery of how living organisms distinguish RNA and DNA building blocks during gene expression, paving the way for the design of new antiviral drugs.

New Bioink Brings 3D-Printing of Human Organs Closer to Reality
Researchers have designed a new bioink that allows small human-sized airways to be 3D-bioprinted for the first time. The 3D-printed constructs are biocompatible and support new blood vessel growth into the transplanted material. This is an important first step towards 3D-printing organs.

Shrinking Pancreatic Tumors by Starving Their Cellular “Neighbors”
Scientists have shown that by blocking "cell drinking", or macropinocytosis, in the tissue surrounding a pancreatic tumor, it is possible to slow the tumor's growth. This suggests that macropinocytosis could be exploited therapeutically.

UK SARS-CoV-2 Variant Spread Rapidly in Care Homes
According to a study, the UK variant of SARS-CoV-2 spread rapidly in care homes in England in November and December last year, broadly reflecting its spread in the general population.

Ultrasound Has Potential To Damage Coronaviruses
Simulations show ultrasound waves at medical imaging frequencies can cause the virus’ shell and spikes to collapse and rupture.

Novel Mechanism Underlying Hair Thinning Identified
Hair grows from stem cells residing in hair follicles and during aging, the follicles lose the capability to grow hair, leading to hair thinning and ultimately hair loss. In a new study, researchers have identified a novel mechanism by which hair follicles lose their regenerative capabilities.

Stem Cells Derived From Fat Show Promise as a Treatment for Mass Radiation Exposure
Researchers have demonstrated, for the first time, how allogeneic adipose-derived stem cells can mitigate total body irradiation-induced acute radiation syndrome.

How SARS-CoV-2 Mutations Enables Immune Evasion Revealed
A new study offers a look into the ways in which compromised immunity may render SARS-CoV-2 fitter and capable of evading the immune system. The research shows that a mutated SARS-CoV-2 from a chronically infected immunocompromised patient is capable of evading both naturally occurring antibodies from COVID-19 survivors as well as lab-made antibodies now in clinical use for the treatment of COVID-19.
