Research: The Scientist Magazine – Summer 2023

The Scientist Magazine (June 1, 2023) – The Summer Issue features bacteria cooperating to benefit the collective, but cheaters can rig the system and biofilms are home to millions of microbes, but disrupting their interactions could produce more effective antibiotics.

Cooperation and Cheating

Pseudomonas Aeruginosa

Bacteria cooperate to benefit the collective, but cheaters can rig the system. How is the balance maintained?


People often recognize social behaviors in complex organisms such as insects, nonhuman primates, and humans. But Megan Frederickson, an ecologist and evolutionary biologist at the University of Toronto, is interested in a different, microscopic social community: bacteria. “Cooperation is everywhere,” she said. “Cells cooperate in multicellular organisms; individuals cooperate in societies; and different species cooperate… Why would it not be the case that microbes cooperate with each other?” 

New Insight into Brain Inflammation Inspires New Hope for Epilepsy Treatment 

Clinicians and researchers teamed up to investigate how inappropriate proinflammatory mechanisms contribute to the pathogenesis of drug-refractory epilepsy.

Doctors treat epilepsy with anticonvulsants to control seizures, but some patients do not respond to these first-line therapies. For patients with drug-refractory epilepsy (DRE) whose seizures persist after treatment with two or more anticonvulsants, clinicians must surgically remove part of the brain tissue to cure the disease.

Covid-19 In 2021: End Is In Sight, Challenges Remain

We enter 2021 surrounded by these rays of hope that the end of the pandemic might be in sight. But monumental challenges remain. Vaccine manufacture, distribution, and uptake are substantial pieces of a complex puzzle that must be completed to reach the 75–90 percent vaccination rate that global health experts say is key to stopping the spread. 

And the virus itself is almost sure to change as it infects more people, possibly becoming more transmissible or dangerous. For instance, as I write this in late December 2020, public health officials in the UK are reporting the rapid spread of a new strain of SARS-CoV-2 that seems to be highly infectious.

This is a perfect example of the continued surprises this pandemic may yet throw at us. But virologists, epidemiologists, drug developers, and other scientists will continue to band together to study this virus and share information that can help humanity address this and future issues appropriately. In addition to careful monitoring of the virus as it mutates and spreads, I fully expect there to be regular monitoring of vaccinated individuals, further refinement of vaccine, and continued development of new COVID-19 therapies. And I can promise that The Scientist will continue to track these developments closely and provide up to date and accurate information about the COVID-19 pandemic and other scientific issues in 2021 and beyond.

Personal Health: “Singing The Praises Of Prevention” (The Scientist Magazine)

From Bob Grant, The Scientist Magazine (April 1, 2020):

Prevention has been playing a growing role in other diseases, infectious and Singing the Praises of Prevention - The Scientist April 2020 - By Andrzej Krauzeotherwise, long before this latest global pandemic. Cancer, the focus of this issue, is ubiquitous, and one would be hard pressed to find a person anywhere on Earth whose life wasn’t in some way touched by the complex and vexing malady. 

This cancer-focused issue features a cover story in which we explore one facet of cancer prevention: exercise. In this feature story, Danish researcher Bente Klarlund Pedersen explains that studies have shown frequent exercise to be useful in avoiding cancer as well as in helping cancer patients lessen the side effects of their cancers and treatments. Her research and that of others is seeking to enumerate the molecular and cellular mechanisms that underlie the benefits exercise seems to offer cancer patients. 

But when one considers the practical ripples that biology sends through societies—issues of public health and the shared goal of minimizing the impact of diseases on a global scale—human behavior and prevention become vitally important.
