Sustained fast rates of evolution explain how tetrapods evolved from fish
One of the biggest questions in evolution is when and how major groups of animals first evolved. The rise of tetrapods (all limbed vertebrates) from their fish relatives marks one of the most important evolutionary events in the history of life. This “fish-to-tetrapod” transition took place somewhere between the Middle and Late Devonian (~400-360 million […]
Can isometric resistance training safely reduce high blood pressure?
When was the last time you had your blood pressure checked? High blood pressure affects 1.13 billion people around the globe and in 2019, it accounted for 10.8 million deaths. Worldwide, it’s the leading risk factor for mortality. More than a third of the Australian population over the age of 18 has high blood pressure, […]
Global ocean warming started later in the 20th century than previously estimated
In estimations of ocean heat content — important when assessing and predicting the effects of climate change — calculations have often presented the rate of warming as a gradual rise from the mid-20th century to today. However, new research from UC Santa Barbara scientists Timothy DeVries and Aaron Bagnell could overturn that assumption, suggesting the […]
7 Signs Of A Nervous Breakdown
By Rosie McCall I’m having a nervous breakdown. You may utter this (or at least think it) when you’re overwrought and ready to snap. But what is a nervous breakdown, exactly? And what should you do when you feel like you’re about to fall apart? Advertisement It turns out “nervous breakdown” isn’t a clinical term. […]
HHS’s Climate Change Office: Not Open Yet, but Getting Positive Reviews
WASHINGTON — Mum’s still the word when it comes to the new Office of Climate Change and Health Equity at HHS, but advocates on the subject seem happy with what they’ve seen so far. The office’s creation was mandated by President Biden in a January 27 executive order on “Tackling the Climate Crisis at Home […]
This touchy-feely glove senses and maps tactile stimuli: The design could help restore motor function after stroke, enhance virtual gaming experiences.
When you pick up a balloon, the pressure to keep hold of it is different from what you would exert to grasp a jar. And now engineers at MIT and elsewhere have a way to precisely measure and map such subtleties of tactile dexterity. The team has designed a new touch-sensing glove that can “feel” […]
I’m Training To Qualify For The Olympic Trials On A Treadmill In My Garage
One evening, when I was 13, my dad asked me if I wanted to go on a run. I had never gone on a run before, but I figured if my dad could do it, I could, too. Dogs barked as we made our way down country roads. The setting sun was making the fields […]
What does a virtual roller coaster ride tell us about migraine?
When experiencing the ups and downs of a virtual roller coaster ride, people who get migraine headaches reported more dizziness and motion sickness than people who do not get migraines, according to a new study published in the July 7, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology. Researchers […]
Disabled Doctors Were Called Too ‘Weak’ To Be In Medicine. It’s Hurting The Entire System.
Diana Cejas was working as a resident physician at a New Orleans hospital when doctors discovered a cancerous tumor on her neck. The tumor had grown larger and more painful over time, eventually metastasizing to her lymph nodes. After Cejas had a successful surgery in July 2012 to remove the lymph nodes, she thought that […]
Scientists observe a new type of topological defect in chiral magnets
“Topological defects” are formed when the symmetry of a magnetic material is disrupted. Domain walls (DWs) are a type of topological defect that separates regions of different magnetic orientations. A widely studied phenomenon, the manipulation of these defects has potential applications in high-performance memory storage devices, energy processing devices, and quantum computing. Recently, the possibility […]
