In new work being presented this week about the effects of exercise on the brain at the Cognitive Neuroscience Society (CNS) in San Francisco, researchers are finding that brain changes that occur after a single workout are predictive of what happens with sustained physical training over time.
Females respond poorly to ketogenic weight loss diet in an animal model
The ketogenic diet recently has been touted for weight loss and improving blood sugar control, but a new study finds that females fail to show these metabolic benefits on this high-fat, very low-carbohydrate diet.

New IR treatment for 'tennis elbow' reduces pain and inflammation without surgery
Tennis elbow, the painful chronic condition that affects up to 3 percent of the US adult population, can be effectively treated through transcatheter arterial embolization (TAE), an image-guided, non-surgical treatment that decreases abnormal blood flow to the injured area to reduce inflammation and pain, according to research presented today at the Society of Interventional Radiology's 2019 Annual Scientific Meeting.
Exposure to HIV virus, treatment before birth linked to obesity later in life

Exposure to tiny air pollution particles may lead to reduced sperm production, suggests new research in mice to be presented Monday, March 25, at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Cost savings from growth hormone insurance strategies not passed on to patients
Increasingly aggressive insurance strategies have lowered the total costs and insurance costs of growth hormone drugs, but those savings are not being passed on to patients, according to new research to be presented Sunday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Investigational obesity drug, oxytocin, weakens brain's reward signals for food
The hormone oxytocin reduces the communication between different brain areas involved in the cognitive, sensory and emotional processing of food cues that people with obesity demonstrate when they look at high-calorie foods, according to research being presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Obesity speeds up the start of puberty in boys, study finds

Screen time plus snacking a risk for metabolic disorder in teens
Teens who sit for hours watching TV, using the computer or playing video games while eating unhealthy snacks are at increased risk for a group of risk factors for heart disease and diabetes, according to research to be presented Monday, March 25, at ENDO 2019, the annual meeting of the Endocrine Society, in New Orleans, La.
BPA exposure during pregnancy can alter circadian rhythms
Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated 'safe' human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Autoimmune diseases are related to each other, some more than others
Researchers using the world's largest twin registry to study seven autoimmune diseases found the risk of developing the seven diseases is largely inherited, but that some diseases are more closely related than others.
Patients bear increased financial burden for growth hormone treatment despite FDA approval
Despite an FDA approval of growth hormone treatment for children with idiopathic short stature (ISS), the mean cost burden to patients and their families has increased over time.
Genetic rickets improves more with burosumab than standard care, study finds
Burosumab, a new injectable medicine to treat X-linked hypophosphatemia (XLH), an inherited form of rickets, demonstrates superior improvements in rickets and other outcomes compared with conventional therapy in an international, phase 3 clinical trial in children.

There is no evidence that ethnic minorities are more sensitive than other groups to supposedly trivial insults or invalidations, they just experience them more often, research from Goldsmiths, University of London shows.
Study highlights detrimental effect of overlooking female athletes' nutritional needs
As poor nutrition can negatively affect everything from bone to reproductive health, more attention needs to be paid to the specific nutritional needs of female athletes, a collaborative study from New Zealand's University of Otago and University of Waikato argues.
Chemicals in household dust may promote fat cell development
Endocrine-disrupting chemicals present in household dust promote the development of fat cells in a cell model and could contribute to increased growth in children relative to their age, according to research to be presented Monday, March 25, at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

Guy's Favorites: What Is Original?
As we transition to our new host Manoush Zomorodi, Guy Raz looks back on some of his favorite episodes from his seven years hosting the TED Radio Hour. This episode originally aired on June 27, 2014.

#548 Land and Ocean Conservation 101
This week we're talking about land and ocean conservation: what it means to protect our land and oceans, the complexities of competing interests and international boundries, and how well Canada is doing at conserving its most important wild areas. Helping us wrap our heads around it are National Parks Program Director Alison Ronson and National Oceans Program Director Candace Newman from the Canadian Parks and Wilderness Society (CPAWS). This episode is hosted by Rachelle Saunders.

Body Count
Right now, at this very moment, all across the planet, there are 7.6 billion human beings eating, breathing, sleeping, brushing their teeth, walking their dogs, drinking coffee, walking down the street or running onto the subway or hopping in their car, maybe reading a summary of a podcast they're about to hit play on ... and the number is only going up. Everyday 386,000 babies are born (16,000 an hour). We're adding a billion new people every 12 years. So here's a question you've probably never thought about: Are there more people alive right now than have ever lived on the planet in history? Do the living outnumber the dead? Robert got obsessed with this odd question, and in this episode we bring you the answer. Or, well, answers. This episode was reported by Robert Krulwich and produced by Annie McEwen and Pat Walters, with help from Neel Danesha. Fact-checking by Michelle Harris. Music and mixing by Jeremy Bloom.
