Exciting breakthrough from our lab! We've synthesized potent Lewis-X-containing triterpenoid saponins that block HIV-1 attachment to immune cells via DC-SIGN & L-SIGN, showing promise as antiretroviral agents. doi.org/10.1002/chem...
Lewis‐X‐Containing Triterpenoid Saponins Inhibit DC‐SIGN‐ and L‐SIGN‐Mediated Transfer of HIV‐1 Infection
Blocking DC-SIGN- and L-SIGN-mediated HIV-1 attachment to immune cells represents a promising strategy for developing antiretroviral agents effective during the early stages of sexual transmission. A...

Wastewater still contains pharmaceuticals that contaminate waterways, contributing to the rise of antibiotic-resistant bacteria. By 2050, superbugs are projected to kill more people than cancer. Scientists are at the frontline to combat antibiotic resistance. #WaterPollution

Spreading misinformation about the Earth's shape threatens critical thinking. Overwhelming evidence, from gravity to satellite imagery, confirms our planet is round. Greek philosopher Eratosthenes accurately measured the Earth's circumference over 2,000 years ago! #ScienceSpeaks

The science is clear: rising CO2 levels trap heat & warm our planet. Primary school students can demonstrate this with a simple "do-it-yourself" greenhouse experiment. It's baffling that some world leaders still refuse to accept these basic facts #ActOnClimate #ScienceMatters

Since the pandemic, people have lost trust in science. Many believe researchers are corrupt. But most researchers have no ties to Big Pharma & are funded by public grants! They set their own research goals, driven by curiosity & a quest for truth. #TrustInScience #EvidenceMatters

Why are scientists underrepresented in politics? It's clear that scientific principles would be a game-changer for managing societies. What's holding my colleagues back? We need them now more than ever to tackle the challenges of our time. #EvidenceBasedPolicy

Scientific humility: Our pursuit of knowledge locally decreases entropy, but are we truly steering the course or following a predetermined path? Is our quest for truth self-directed or part of the universe's larger plan? #Science #Philosophy #FreeWill

With all the recent technological advancements, why do humans still work so much? It's time to rethink our capitalist system driven by profit & greed. Why work for personal gain when we can work for the greater good? Let's prioritize people over profits!

As humans, we lack a unified purpose. In the face of our solitude in the universe, collaboration is our only viable path forward. It's time to revisit our core values. Why work in isolation? Governments must adopt a universal perspective in their policymaking. There's still hope for a better future.
