Neoliberalism slows down evolution! Just kidding…or am I? 🧐😁🤣🙈.

Like other organisms, bacteria constantly have to fight to survive in hostile living conditions. Together with colleagues in Finland, researchers at the Max Planck Institute for Evolutionary Biology in Plön have discovered that bacteria adapt to their environment more slowly and less efficiently as soon as they are exposed to two stress factors rather than one. This is due to mutations in different genes. The slower rate of evolution led to smaller population sizes. This means that evolution can take divergent paths if an organism is exposed to several stress factors.

Bacteria rarely live alone; they are usually part of a community of species that is exposed to various stress factors. They can often react to these factors by adapting to new environmental conditions with astonishing speed. Antibiotics that enter soil and water via waste water and accumulate there in low concentrations can trigger the evolution of resistance in bacteria – even though these concentrations are so low that they inhibit bacterial growth only slightly or not at all. However, bacteria do not only have to fight antibiotics; they also have to deal with predators. This is why they often grow in large colonies that cannot be consumed by predatory organisms.

Starting on Thursday, the latest Apple Watch models will be able to take an ECG reading, a kind of heart-rate reading that doctors can use to diagnose heart conditions.

To activate the feature, you need the Apple Watch Series 4 and the latest version of WatchOS, which will be available for download on Thursday.

Apple made it easy to access the feature: turn on the app, hold your finger on the device’s crown for 30 seconds, and it will provide a heart rhythm reading that you can use to figure out whether you need to contact your doctor to get your heart checked out. It saves the reading in a PDF file that you can send to your doctor.

Slimy, hard-to-clean bacterial mats called biofilms cause problems ranging from medical infections to clogged drains and fouled industrial equipment. Now, researchers at Princeton have found a way to cleanly and completely peel off these notorious sludges.

A large team of researchers has developed a new way to classify patients with Alzheimer’s disease, suggesting we should think of the disease as six distinctly different conditions instead of one single disease.

Inexpensive procedure shows whether patient has cancerous cells in the body, but does not reveal where or how serious it is.

One of the biggest obstacles to transplanting organs from one person to another is that the immune system of the person getting the new life-saving organ often tries to reject it. The immune cells see the new material as “foreign” and attacks it, sometimes destroying it.

Right now, the only way to prevent that is by using powerful immunosuppressive drugs to keep the patient’s immune system at bay and protect the new organ. It’s effective, but it also comes with some long-term health consequences.

But now researchers at Tel Aviv University in Israel say they may have found a way around that, using the patient’s own stem cells.

The Fourth Eurosymposium on Healthy Ageing (EHA) was held in Brussels on November 8–10, 2018, and we had the opportunity to give talks about aging, advocacy, and engaging new audiences.

The EHA is a conference hosted every two years by Heales, and it sees like-minded people from the research and advocacy community come together to share knowledge and listen to talks from various researchers and other experts in the field. We were very pleased to be invited to give two presentations during the conference and share our knowledge and experience with the audience there.
