Architecture is key: Biomolecule metal–organic hybrids with high bioactivity
Biomacromolecules incorporated into tailored metal–organic frameworks using peptide modulators are well shielded but highly active thanks to carefully tuned nanoarchitecture. As scientists report in the journal Angewandte Chemie, this strategy can be used to synthesize an “artificial cell” that ...
Coronavirus could be transmitted through a long-lasting cloud of virus-containing aerosol droplets ejected from a flushing toilet
Researchers used a computer simulation to show how a flushing toilet can create a cloud of virus-containing aerosol droplets that is large and widespread and lasts long enough that the droplets could be breathed in by others. With recent studies showing the novel coronavirus that causes COVID-19 ...
New study explains the mechanisms, symptoms, and diagnosis of the new coronavirus
COVID-19, the disease caused by coronavirus SARS-Cov-2, has infected over 4 million people in 212 countries, of whom at least 272,000 have died. The ongoing economic and social impact of the pandemic is staggering, but despite a daily flood of news on the disease, few laypeople know that ...
A good indicator of dysregulation in live cells is a change in their RNA expression. MicroRNA (miRNA), a special type of RNA, is considered a biomarker for carcinogenic cells. A team of scientists from China has found a way to amplify miRNA in live tumor cells for bioimaging. As they report in ...
APEIRON Biologics AG announced the launch of a Pilot investigator-initiated clinical trial (IIT) with APN01, a recombinant human angiotensin-converting enzyme 2 (rhACE2), to treat patients with severe coronavirus infection in the People's Republic of China. The randomized, unblinded trial will ...
The origin of lives of human beings, animals and plants on earth is attributed to chirality because it is necessitated for the formation of biomolecules, such as nucleic acids, proteins, carbohydrates, etc. The studies on chirality have been becoming increasingly active and extensive due to its ...
Emerging viral infections--from bird flu to Ebola to Zika infections--pose major threats to global public health, and understanding their origins can help investigators design defensive strategies against future outbreaks. A new study provides important insights on the potential origins of the ...
New approach to selective chemotherapy
A novel drug, named “FerriIridium”, can simultaneously help diagnose and treat gastric cancer. The initially weakly active precursor (prodrug), based on an iridium-containing compound, is selectively activated only after reaching the interior of a tumor cell. This is possible because of the ...
Biomimetic hydrogel with photodynamic antimicrobial effect
Infections are a dreaded threat that can have fatal consequences after an operation, in the treatment of wounds, and during tissue engineering. Biomimetic hydrogels with “built-in” antimicrobial properties can significantly decrease this danger. In the journal Angewandte Chemie, scientists have ...
Most images captured by a camera lens are flat and two dimensional. Increasingly, 3D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4D imaging, which adds information on light polarization, could open up even more possibilities, but ...
