“In their work, Hamiliton’s team found that the Dunkin Hartley guinea pig was a good candidate for a muscle aging model due to the animal’s tendency to develop osteoarthritis (OA) at a young age.”


There are many components to aging, both mental and physical. When it comes to the infrastructure of the human body—the musculoskeletal system that includes muscles, bones, tendons and cartilage—age-associated decline is inevitable, and the rate of that decline increases the older we get. The loss of muscle function—and often muscle mass—is scientifically known as sarcopenia or dynapenia.

For adults in their 40s, sarcopenia is hardly noticeable—about 3% is lost each decade. For those aged 65 years and older, however, can become much more rapid, with an average loss of 1% muscle mass each year. More importantly, sarcopenia is also marked by a decrease in strength, impaired gait, reduced physical activity, or difficulty completing everyday tasks.

The proportion of older adults aged 65+ is projected to more than double by the year 2060, driving research into the process of musculoskeletal decline. Researchers at Colorado State University’s Columbine Health Systems Center for Healthy Aging believe they have found an that will help them better understand it and find ways to curtail the symptoms.

Review: Meat Planet (2019) by Benjamin Aldes Wurgaft

In the words of the book’s author, Benjamin Aldes Wurgaft, Meat Planet: Artificial Flesh and the Future of Food (2019) is “not an attempt at prediction but rather a study of cultured meat as a special case of speculation on the future of food, and as a lens through which to view the predictions we make about how technology changes the world.” While not serving as some crystal ball to tell us the future of food, Wurgaft’s book certainly does serve as a kind of lens.

Our very appetites are questioned quite a bit in the book. Wondering about the ever-changing history of food, the author asks, “Will it be an effort to reproduce the industrial meat forms we know, albeit on a novel, and more ethical and sustainable, foundation?” Questioning why hamburgers are automatically the default goal, he points out cultured meat advocates should carefully consider “the question of which human appetite for meat, in historical terms, they wish to satisfy.”

Wurgaft’s question of “which human appetite” – past, present, or future – is an excellent one. If we use his book as a lens to observe other emerging technologies, the question extends well beyond our choices of food. It could even have direct implications for such endeavours as radical life extension. Will we, if we extend our lifetimes, be satisfactory to future people? We already know the kind of clash that persists between different generations, and the blame we often place on previous generations for current social ills, without there also being a group of people who simply refuse to die. We should be wary of basing our future on the present – of attempting to preserve present tastes as somehow immutable and deserving immortality. This may be a problem such futurists as Ray Kurzweil, author of The Singularity is Near (2005) need to respond to.

Dr. Halima Benbouza is an Algerian scientist in the field of agronomic sciences and biological engineering.

She received her doctorate in 2004 from the University Agro BioTech Gembloux, Belgium studying Plant Breeding and Genetics and was offered a postdoctoral position to work on a collaborative project with the Agricultural Research Service, United States Department of Agriculture in Stoneville, Mississippi.

Subsequently, Dr. Benbouza was funded by Dow Agro Science to study Fusarium wilt resistance in cotton. In 2009 she was awarded the Special Prize Eric Daugimont et Dominique Van der Rest by the University Agro BioTech Gembloux, Belgium.

Dr. Benbouza is Professor at Batna 1 University where she teaches graduate and postgraduate students in the Institute of Veterinary Medicine and Agronomy. She also supervises Master’s and PhD students.

From 2010–2016, Dr. Benbouza served as inaugural Director of the Biotechnology Research Center (CRBt) in Constantine, appointed by the Ministry of Higher Education and Scientific Research. In 2011, she was appointed by the Algerian government as President of the Intersectoral Commission of Health and Life Sciences. Dr. Benbouza is a member of the Algerian National Council for Research Evaluation and a past member of the Sectorial Permanent Board of the Ministry of Higher Education and Scientific Research.

In 2013, Dr. Benbouza was appointed by the Prime Minister as President of the steering committee of Algeria’s Biotech Pharma project. In 2014 she was honored by the US Embassy in Algiers as one of the “Women in Science Hall of Fame” for her research achievements and her outstanding contribution to promote research activities and advance science in her country.

0:00 Introduction.

Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 virus more efficiently.

Using special molecular tags, the team was able to reduce the five-to-15 percent error rate of Oxford Nanopore Technologies’ MinION device to less than 0.005 percent—even when sequencing many long stretches of DNA at a time.

“The MinION has revolutionized the field of genomics by freeing DNA sequencing from the confines of large laboratories,” says Ryan Ziels, an assistant professor of civil engineering at the University of British Columbia and the co-lead author of the study, which was published this week in Nature Methods. “But until now, researchers haven’t been able to rely on the device in many settings because of its fairly high out-of-the-box error rate.”

Invasive round goby fish have impacted fisheries in the Great Lakes and the Finger Lakes by competing with native species and eating the eggs of some species of game fish.

But the camouflaged bottom dwellers can be difficult to find and collect—especially when they first enter a new body of water and their numbers are low and they might be easier to remove.

In a proof-of-principle study, Cornell researchers describe a new technique in which they analyzed environmental DNA—or eDNA—from in Cayuga Lake to gather nuanced information about the presence of these invasive fish.

ABC News: German authorities accuse Australian man of running DarkMarket, the world’s largest illegal online marketplace.


An Australian is allegedly at the centre of what German authorities believe was the biggest illegal marketplace on the darknet where more than $220 million was transacted over sales of drugs, forged money, SIM cards and bogus credit cards.

A major risk of being hospitalised is catching a bacterial infection.

Hospitals, especially areas including intensive care units and surgical wards, are teeming with bacteria, some of which are resistant to —they are infamously known as ‘superbugs’.

Superbug infections are difficult and expensive to treat, and can often lead to dire consequences for the patient.
