Ancient DNA reveals farming led to more human diseases

"Humans' close cohabitation with domesticated animals—and large-scale migrations of pastoralists from the Pontic Steppe—played a decisive role in the spread of these diseases...We've long suspected that the transition to farming and animal husbandry opened the door to a new era of disease—now DNA shows us that it happened at least 6,500 years ago. These infections didn't just cause illness—they may have contributed to population collapse, migration, and genetic adaptation."

🌱 International Day of Plant Health🌱

Today, we highlight an often-overlooked topic: plant health – vital for food security, biodiversity, and sustainable agriculture.

In our current research at Hochschule Bonn-Rhein-Sieg and Julius Kühn-Institute, we’re tackling a key question:
How can we detect plant diseases and pests before visible symptoms appear?

🔬 The answer: With the nose of chemistry!
We analyze volatile organic compounds (VOCs) that plants emit when under stress or attacked by
🦠 bacteria,
🍄 fungi, and
🪲 insect pests.

Using advanced GC-MS technology (gas chromatography-mass spectrometry), we aim to identify these unique molecular “scent signatures” and use them as an early-warning system to detect harmful organisms before they cause damage.

🧪 Our goal: to “sniff out” plant diseases and pests.

How a Changing Climate Is Reshaping the Spread of Infectious Diseases

"...Then you have this convergence of crises—the #ClimateCrisis overlapping with the #PollutionCrisis. So you get this intersection between air pollution and respiratory #diseases, and then infectious diseases more broadly, all layered on top of a changing #climate.

When it comes to waterborne and foodborne diseases, the link to #ClimateChange is even more direct. As temperatures rise, you create more favorable conditions for #bacteria and other #pathogens to multiply. They thrive in warm environments—soil, water, contaminated areas—so warming can increase their abundance.

#ExtremeWeather events are also a big factor here. Aedes #mosquitoes need water to complete their life cycle—from egg to larva to pupa, it all happens in #water. When #floods occur, all the discarded #plastic and #trash lying around fill with water and becomes the ideal breeding ground for mosquitoes.

What’s interesting is that these diseases aren’t just associated with floods—they’re also linked to #droughts. That might seem counterintuitive at first, but in many parts of the world, people don’t have safe, reliable access to clean water, especially during drought conditions. So they store water in containers that aren’t properly sealed or protected, which too can become the perfect breeding sites for mosquitoes.

Infections—particularly vector-borne diseases—are increasingly reemerging and emerging in new areas around the world for a lot of different reasons. Climate change is definitely part of that, with rising temperatures and more extreme weather events like floods and droughts. But the way we live our lives and interact with the environment also plays a huge role. I mean, first and foremost, most of us now live in urban areas rather than rural ones..."

Pathogens and treatment of a local infection

In case of local infection with such diseases such as: prostate abscess, lymphangitis, dental abscess, the causative agents of which are Pseudomonas aeruginosa, Proteus, Enterococcus, gonococcus, Escherichia coli, beta-hemolytic
streptococcus, streptococcus viridans, anaerobic staphylococci, penicillin is used, oxacillin, ampicillin, erythromycin, cephaloridine.

New #antibiotic that kills #drugresistant #bacteria discovered in technician’s #garden
It targets bacteria’s protein-making factory, the #ribosome, in a way that other antibiotic drugs don’t. Ribosome is an attractive antibiotic target because bacteria don’t easily develop resistance to #drugs targeting the structure. In studies, #lariocidin slowed the growth of a range of common bacterial #pathogens, including many multidrug-resistant strains.
