When you are faced with a choice — say, whether to have ice cream or chocolate cake for dessert — sets of brain cells just above your eyes fire as you weigh your options. Animal studies have shown that each option activates a distinct set of neurons in the brain. The more enticing the offer,

Mum Claire Taylor thought little of it when she caught herself on a car door and sustained a tiny cut to the corner of her left eye. But within 36 hours, the 47-year-old’s face had swollen dramatically and she had become delirious, drifting in and out of consciousness. The only other person at home with

A group of researchers from the University of Toronto have developed a credit-card sized tool for growing cancer cells outside the human body, which they believe will enhance their understanding of breast cancer metastasis. The device, described in a paper published today in Science Advances, reproduces various environments within the human body where breast cancer

Oreos are a classic pantry staple — something we’re all stocking up on these days. But they’re not exactly a luxurious dessert. Sure, they’re tasty but they don’t really compare to a warm and gooey chocolate chip cookie straight out of the oven, right? Well, if you’re Chrissy Teigen they do. Teigen shared a recipe

Each day, humans and animals rely on habits to complete routine tasks such as eating and sleeping. As new habits are formed, this enables us to do things automatically without thinking. As the brain starts to develop a new habit, in as little as a half a second, one region of the brain, the dorsolateral

The truth is an ephemeral thing on the internet, and also when it comes to boundary-pushing artists. Even knowing that, when we started seeing headlines today about Grimes creating an Instagram and Twitter account for her unborn child, it took a minute for us to curb our initial excitement. On the surface, it seemed like

Zika virus infection can stunt neonatal brain development, a condition known as microcephaly, in which babies are born with abnormally small heads. To determine how best to prevent and treat the viral infection, scientists first need to understand how the pathogen gets inside brain cells. Employing different approaches to answer different questions, two research teams

DR ELLIE CANNON: Has diabetes put my sex drive into reverse? I was diagnosed with type 2 diabetes two years ago and have seen a significant decrease in my sex drive since then. I’m 72 and don’t expect to be as active as I was in my 20s, but my wife is beginning to worry

New research has shed light on the origins of spinocerebellar ataxia type 7 (SCA7) and demonstrates effective new therapeutic pathways for SCA7 and the more than 40 other types of spinocerebellar ataxia. The study, which appears online Monday on the website of the journal Neuron, implicates metabolic dysregulation leading to altered calcium homeostasis in neurons

You’re flipping through the television channels when you hear the familiar beginning strains of a Sarah McLachlan song. You hastily click to the next channel, before the haunting images of homeless animals appear. Or you’re scrolling through the news one morning when a headline makes you pause—a mass shooting, perhaps, or a tsunami halfway across

Researchers have cleared a major obstacle in the development of an HIV vaccine, proving in animal models that effective, yet short-lasting antibodies can be coaxed into multiplying as a fighting force against the virus. The finding, led by a team of researchers at the Duke Human Vaccine Institute (DHVI) and Boston Children’s Hospital, publishes online

As in other countries, the Australian health care system has limited capacity to rapidly move a future treatment for Alzheimer’s disease from approval into wide clinical use, which could leave thousands of older people without access to transformative care if such a breakthrough occurs, according to a new study by RAND Australia. The most pressing

A new study published today by researchers from Baylor College of Medicine and UT Health’s McGovern Medical School in the Proceedings of the National Academy of Sciences reveals an unprecedented close-up view of cilia linked to blindness. Cilia are short hair-like structures found on the surface of certain cells. They are particularly important in vision

Attention-deficit hyperactivity disorder (ADHD) is a widespread condition with complex underlying causes. A stimulant drug called methylphenidate is a common ADHD treatment that impacts the brain’s levels of dopamine, a neurotransmitter involved in systems of reward; however, methylphenidate has a potential for abuse, and its therapeutic effects are poorly understood. To explore methylphenidate’s varied interactions

Depression has traditionally been linked to increased inflammation. Innovative research by psychologist Eiko Fried refutes this popular assumption. He shows that specific depression symptoms such as sleeping problems explain this relationship. Publication in Psychological Medicine . Over the past few decades, there have been many studies into the relationship between depression and inflammation in the

Physical inactivity is a global health problem. But despite overwhelming evidence that regular exercise is highly beneficial, the challenge of encouraging people to be more active remains. Often “lack of time” is the reason given for not exercising. To address this, many sport and exercise scientists recommend what is known as High-intensity Interval Training (HIT).

Australian scientists have led the development of the world’s most detailed gene map of the human retina, providing new insights which will help future research to prevent and treat blindness. The retina is the latest part of the human body and the first part of the eye to be mapped as part of the Human

So, you made a big meal and now you have a heaping helping of leftovers to contend with. You pour them into assorted containers and bags, then slide them into any spot in your fridge with a little space. Of course, we all know what may very well happen — those leftovers languish in the

Starting this summer, physicians at UC Davis Health will be able to use a powerful new scanner that can render detailed, 3-D images of the inner workings of the entire human body in as little as one minute, the creators of the device announced recently. UCD researchers Ramsey Badawi and Simon Cherry said the sophisticated

For the first time, researchers have mapped the building blocks of the human lungs and airways, in both asthma patients and normal people. The research from the Wellcome Sanger Institute, University Medical Center Groningen, Open Targets, GSK and collaborators revealed the identity of each cell type, creating the first draft Human Cell Atlas of the
