Five science books to add to your 2018 reading list

Turn off whatever device you’re reading this on, and go pick up a book instead. Honestly, it’s the only sane way to deal with modern life. Non-fiction books in particular are vital in understanding the basic principles that make today’s world what it is. They can help us all decide how to tread the best path through it.

Still here? Perhaps you need a little advice on what to pick up? In that case, you’ve come to the right place. ScienceSeeker's editors have chosen some of the favourites we’ve read this year, which lift the veil on gender, trees, the animals we eat, our feeling for time, and how science emerges from chance. Have a read of any or all of them, and inform yourself!

Andy Extance, chemistry and physics editor and ScienceSeeker editor in chief's pick is Inferior by Angela Saini. He says:
In an extremely readable way, Saini explores how the 'just so' stories that science supposedly tells us about human gender, and specifically women's inferior qualities, often don't bear great scrutiny. Evolutionary psychology explanations are often built on studies of animals where males dominate and overlook those species where females do. Anthropology studies that imply that women's place is in the home similarly overlook evidence to the contrary. For example human mothers kill their babies or leave them to die, which suggest that motherhood in particular is not innate. Saini both brings together the best, latest, evidence and explores the internal politics of science that has distorted our attitudes to women. I highly recommend you read Inferior, and find out about the real story of women and men.

Jennifer Tsang, ecology and policy editor's pick is Hidden Life of Trees by Peter Wohlleben. She says:
Trees are everywhere, but we often walk amidst them without wondering about their daily lives. What controls the come and go of leaves with the seasons? How do they survive such drastic changes in temperature? How do trees communicate with one another – how do they cooperate or compete with each other and other species? These are just a few of the questions that Wohlleben addresses to describe the amazing ways tree survive and evolve. Written to educate and entertain, I found myself fascinated over and over again throughout this book.


Recent scientific developments are radically changing how we see and understand animals. By engaging with research from a wide range of disciplines, Professor of Anthropology, Barbara J. King, addresses the dissonance between how we feel about our non-human cohabitants and what we choose to eat – in turn creating a nuanced, thoughtful and provocative book.

Teodora Stoica, neuroscience editor's pick is: Your Brain is a Time Machine: The Neuroscience and Physics of Time by Dean Buonomano. She says:
This book explores how the human brain not only tells time but creates it, engagingly explaining the concept of “mental time travel” and addressing profound questions such as: “What is time?” and “Is our sense of time’s passage an illusion?” Illustrating these ideas using multi-disciplinary data, Buonamano's book is an engaging and entertaining book that makes time fly by.



Thanassis Psaltis, art, photography, physics and general science editor's pick is: Causality and Chance in Modern Physics by David Bohm
This book was published in 1957, when there was a lot of discussion on the interpretation of the quantum theory, despite the fact that the Copenhagen interpretation pioneered by Bohr and Heisenberg was widely accepted by physicists. The book has a foreword by Louis de Broglie, one of the pioneers of quantum physics, who postulated in his PhD thesis that matter behaves like waves. Prof. Bohm discusses in a very concise way how causality and chance can describe physical laws and he presents his interpretation of the quantum theory. It's great reading for science students, since Prof. Bohm, one of the most rounded scientists of the twentieth century, guides the reader into the inner workings of natural laws, using quantum mechanics as an example.

ScienceSeeker picks 2017 highlights: Investigating the interplay between Mind and Machine

The works of Isaac Asimov, to me, always seemed to be the stuff of pure magic. It was incomprehensible that in the near future we would live in a society where machines would be smoothly integrated into our daily lives. The first step towards that seeming impossibility was the advent of smartphones. Now, we can connect with friends on the opposite side of the world, send in work emails, casually scroll through pictures of travel destinations and the hottest restaurants, all while sipping the morning cup of coffee. Smartphones have become so enmeshed into our daily routines that it is impossible to ignore the sea of people with heads bent over their screens. And so, when ScienceSeeker asked me to choose some highlights of the post its editors have picked as their favourites in 2017, smartphones were always likely to be among them.

For example, it turns out there is a biological component to our smartphone fixation. Smartphones cause changes in the ratio of the neurotransmitters gamma aminobutyric acid (GABA), glutamate and glutamine (GLX). A study conducted on teenagers showed that the ratio of GABA to Glx was higher in the cortex of internet- and smartphone- addicted youth compared to the healthy controls. An imbalance in this ratio leads to drowsiness and anxiety. Further studies will elucidate the clinical implications of this finding and determine whether the emotional problems are the cause or consequence of this media addiction.

However, our modern machines can clearly be beneficial, and this year video games have been studied as an option for treating kids with ADHD. Akili Interactive Labs has designed a game that target specific neural pathways leading to cognitive improvement. The targeted algorithms are aimed at producing the same beneficial effect as ADHD drugs, without the side effects. The company is now focusing on similar video games for treating adults with depression, patients with pediatric autism, and those with multiple sclerosis.

Virtual reality technology is now exciting avid video game players – and scientists. Researchers are combining virtual reality with visualization software to explore the 3D structure of the brain. This will allow scientists to perform visual dissections of the brain instead of depending on traditional microscopic slides of 2D slices. Furthermore, scientists can now trace individual neurons by slipping on the virtual reality headsets. This is a vast improvement over the current software programs that require constantly rotating 2D images to visualize the path of a neuron; a cumbersome process considering that a cubic millimeter of the brain has approximately 300 million neural connections. The new technology borrows graphic techniques from the “Harry Potter” franchise, and so it is hardly surprising that the results seem to be magical!

The Science of Star Wars

Is it possible to create a lightsaber? Could the Force ever be a reality? ScienceSeeker editor and McMaster University PhD student Thanassis Psaltis explores the real science behind the fictional Star Wars universe.

Since the first Star Wars movie opened in 1977, children the world over have been channelling their inner Obi Wan Kenobi – trying in vain to move objects using the mystical power of the Force.

While it may not be possible to levitate the TV remote using Jedi powers, science tells us that, in fact, there are forces that bind the galaxy together, planets that resemble those found in the Star Wars universe, and that it may – theoretically at least – be possible to build a lightsaber.

And that’s just the tip of the iceberg. According to Thanassis Psaltis, a first-year PhD student in experimental nuclear astrophysics, Star Wars is full of interesting science.

To mark this week’s release of the latest installment of the Star Wars saga, Psaltis who is supervised by Alan Chen, a professor in McMaster’s Department of Physics and Astronomy, recently explored the science of Star Wars in a unique show he created and presented at McMaster’s W.J. McCallion Planetarium:

The holidays are upon us, with people everywhere beginning their annual migrations to be with family for a few days of eating, drinking, exchanging presents and catching up. However, most people will also have relatives whose views are radically different from theirs – and seem to bring them up at the most embarrassing time possible. If you are a scientist yourself, or simply a science enthusiast, one of the most challenging breeds of embarrassing relative is undoubtedly the science-denier. You want to help them, while at the same time you probably don't want to argue under the Christmas tree. Here are some of my best-tested top-tips for dealing with your festive nightmare.

When scientists disagree: 5 (or 6) steps to understanding scientific controversy

With real scientists, the gloves are off. Credit: Ryan McGuire/StockSnap
by Gaia Cantelli, PhD

US scientists’ research on how to promote healthy eating in schools is deeply flawed, watchdog researchers have found. The original studies gained much media attention, secured millions of dollars in funding and are being implemented in thousands in schools. But independent scientists have found that they are filled with problems, including mathematical impossibilities and duplications. 

If you ever look up scientific theories online, it won’t be long until you encounter at least one story like this. Because science is a living subject and constantly evolving, scientists will inevitably disagree and controversy will arise. Choosing who to believe when you are not a subject expert yourself is tricky and confusing, especially if you are trying to use science to make an important decision. Here are 5 (or maybe 6) steps you might want to consider to make up your mind.

by Gaia Cantelli, PhD

You have just woken up. You check your phone and have a look at the news. What do you see? Most days, a key headline will have something to do with science – and with good reason. We live in what many consider a golden age of discovery. Science is making advances we never thought possible and is helping us work out problems we never thought could be solved. We can look for water in outer space, use light-activated nanoparticles to kill antibiotic-resistant bacteria and use drugs to correct errors in our DNA to fend off deadly genetic diseases.

However, that’s only one side of the coin. At least half of the science news seems to be urgently pointing at a new problem. Just over the past few weeks, even the most casual news-readers could have found themselves worrying about involuntarily increasing their risk of getting breast or lung cancer by doing apparently healthy things like going outside and taking vitamins. You may have been stressing about compromising your heart’s health by sitting too much or being too tall. And that’s before you’ve even gotten out of bed!

So how can you use science to make more informed decisions? Here are a few pointers to empower you to make a change.

If you wanted to know more about a medical condition would you take a trip to the library and pore over medical textbooks? Of course not, you’d look it up on your phone while you’re still in your doctor’s waiting room.

Looking up things online is essentially second nature for most of us – but do you ever worry if you can trust what you find? Most of us get all our information from the Internet – and science and medicine have been made far more accessible by the Internet and mobile phones. It’s incredibly convenient, but it is also a minefield of potential misinformation, misunderstanding and, even worse, fraud. How can we know if we can trust what we see online? Here are some of my best pointers to use this amazing resource to obtain reliable and relevant information – especially when it comes to science and medicine.
