The efficiency of delivery of DNA vaccines is often relatively low compared to protein vaccines. The use of superparamagnetic iron oxide nanoparticles (SPIONs) to deliver genes via magnetofection shows promise in improving the efficiency of gene delivery both in vitro and in vivo.

On the cold, rainy morning of July 16, 1945, a group of scientists and soldiers gathered in New Mexico’s Jornada del Muerto desert. Atop a 100-foot steel tower they had placed a large metal ball studded with plugs and wires. The “gadget,” as they called it, was a code word for their secret weapon. Inside it sat another globe made of high explosives, and inside that was a core of subcritical plutonium. This device was the first nuclear explosive, a prototype bomb built to end a war.

The Government has admitted for the first time that Sellafield ‘is a source of plutonium contamination’ across the country. Public Health Minister Melanie Johnson has revealed that a study funded by the Department of Health discovered that the closer a child lived to Sellafield, the higher the levels of plutonium found in their teeth.

Scientists are anxiously searching for an effective antiviral to combat severe or critical COVID-19, which has already caused over a million deaths worldwide. A new study published on the preprint server bioRxiv* reports the elucidation of the mechanism of inhibition of SARS-CoV-2 by a non-nucleotide inhibitor called suramin. This is the first such compound to be shown to have such activity and shows promise for use as a repurposed drug against COVID-19.

Rocket Science Debunks Climate Change Pseudoscience

Written by Joseph Postma

I would like to draw your attention to an excellent discussion and real-world example of how practical experimental science debunks the postulated notions of radiant fluxes and temperatures adding together as is envisioned at the very basis of climate science in its falsely-named and non-existent “greenhouse effect”.

An “avalanche” of “expanding and accelerating” demographic forces is driving global birth rates down at alarming rates, demographers warned The New York Times. “A paradigm shift is necessary,” German demographer Frank Swiaczny, former United Nations chief of population trends and analysis, told the Times. “Countries need to learn to live with and adapt to decline.”
