Prey animals must constantly stay alert and rely on publicly available information to avoid being eaten, find suitable foraging and mating opportunities, and to assess local competition for resources. Reliable information allows prey to make behavioural decisions in order to ensure sufficient foraging and mating gains while reducing predation risks. However, complete information is rarely available to prey.
Humans love flowers! We admire their varied colors and shapes, enjoy the way they smell, and (especially on a day like today) give them to those we love. But why has this affection for flowers evolved in us – given that flowers have certainly not evolved to impress us? In fact, we gain very little benefit (apart from joy) from them. It is true that some flowers are edible, and that flowers may indicate where an edible part of a plant can be found
Technological advances have provided immense improvements in our lives, but often with a hidden cost. Even the historic skills of bronze and iron working were driven by a desire not only for ploughs and tools, but for better weapons of war. This is still the case for much of modern science. Technical knowledge has helped to combat diseases, improve health, provide more food, offer faster travel, or ease hardship, and this is progress.
What are addictive disorders? Are they indeed disorders? The nature of problematic psychoactive substance use continues to be a matter of controversy among the public and politicians; even among health professionals there is little consensus. Some have a view that repeated use of a substance (or gambling or gaming) represents personal choice (a “free-will decision”) even when problems are occurring.
The hack of the Democratic National Committee by the Russian government and the subsequent publication of confidential emails during the 2016 US presidential election elevated cyber security in the context of international affairs to an unprecedented level in the public’s consciousness, not only in the United States but around the world.
Can magicians (illusionists) really levitate themselves and others or bend spoons using only the power of their mind? No. Emphatically no. But they surely make it seem as if they can. Enjoy being fooled? Then you’ll love watching really good magic shows that allow people the opportunity to suspend their disbelief momentarily. But don’t let this suspension become permanent.
When people asked me what I did for a living, some were curious and wanted to know more, while others looked at me as if I were selling snake oil. Nowadays, these conversations are slightly different. Although it is still not always well understood as a profession, more people are familiar with the term “music therapy” and open to the idea that music and other creative mediums may be used to promote health and well-being.
Ask anyone about their experience with their own or a loved one’s cancer, and the response will likely include a story or remark about an oncologist, surgeon, nurse, or other health care provider. These are often positive stories: the oncologist who remembered a child’s birthday, the nurse who stayed after his shift to wait with an elderly patient until her daughter arrived to pick her up, or the surgeon who attended a husband’s funeral.
AIDS is a fast moving epidemic and some of the data and assertions were immediately out of date. For example, the book failed to foresee the massive expansion in treatment. In 2008, there were 28.9 million people living with HIV, and a mere 770 000 were receiving anti-retroviral drugs. By 2015, there were 36.7 million people infected with HIV, but 17 million were on treatment.
Cute and heartwarming videos of dogs fill the internet. My favourite is the bacon dog tease, but others catch my attention because they reveal extraordinary animal behaviours. For example, there are many of dogs helping other animals, like opening the back door to let in a friend. Dogs are our best animal friends, but there is a new contender. The pig might not be agile enough for Frisbees, or into making ‘guilty faces’, but like dogs, might save your life in the future.
In 2011, the US Preventive Services Task Force (USPSTF) issued its controversial draft recommendation against measuring prostate-specific antigen (PSA) in blood to screen for prostate cancer, claiming the test didn’t save lives. USPSTF is an independent panel of national experts convened by Congress to make evidence-based recommendations on preventive care.
We will all spend about one third of our lifetime asleep, deprived of this precious ability to act and to react. During these long idle hours, little is perceived from the external world and little is remembered. For some, sleep is a refuge. For others, it is just a saddening waste. Yet, all animals, from fruit flies to humans, need to sleep and scientists have proven, time and time again, the variety of benefits that sleep has on the body and most importantly, on the mind.
One of the defining battles of modern medicine has been the ongoing fight against cancer, a disease that has no doubt affected many of you either directly or indirectly. Whilst there have been huge advances in detection and treatment, cancer remains a major global health problem, with 8.2 million people dying from the disease every year. World Cancer Day aims to save millions of preventable deaths each year by raising awareness and education about cancer.
The growth of hospital medicine in 19th century India created a space–albeit a very small one–for providing Western-style healthcare to female patients. Many of these changes, including the reform of reproductive healthcare and the spread of women’s medical education, benefitted a privileged minority belonging to urban, higher-caste groups. The reform in women’s healthcare in colonial India constitutes a significant chapter of the country’s social history and laid an irrevocable foundation for medicine in the post-independence period.
The field of physical therapy encompasses not only rehabilitation after injury and surgery but also a wide range of preventive health services and vital lines of research. Dr. Alan Jette, PT, PhD, Editor-in-Chief of Physical Therapy (PTJ), the scientific journal of the American Physical Therapy Association, shares his vision for PTJ and his take on opportunities and challenges for the physical therapy profession.
In present-day Western Europe and North America, the dementia research field is in as much political turmoil as mainstream politics. And the struggling forces at play in both domains are often the same: individual activity or collective solidarity, technological solutions or community development/public health, for-profits versus nonprofits, unbridled capitalism or regulatory constraint.
