The gut microbiome is one of the fastest moving areas of science today.
For migraine sufferers with obesity, losing weight can decrease headaches
For migraine sufferers with obesity, losing weight can decrease headaches and improve quality of life, researchers from Italy and the United States report.
CPAP machine improves weight loss in dieting adults with obesity, sleep apnea
When trying to lose weight by cutting calories, people who have obstructive sleep apnea (OSA) in addition to obesity can lose more weight if they treat their sleep disorder with an overnight CPAP, or continuous positive airway pressure, machine.
Another possible consequence of the opioid epidemic: hormone deficiencies
Many people who use opioid medications long term do not produce enough testosterone or another important hormone, cortisol, according to a new study.
In healthy young women, sleep quality varies throughout the menstrual cycle
Young women are more likely to experience sleep disruption in the days leading up to their menstrual period, according to a new study that will be presented Saturday at ENDO 2019, the annual meeting of the Endocrine Society, in New Orleans, La.
Race, ethnicity influence fracture risk in people with diabetes
Caucasians and Hispanics with diabetes have a greater risk of fracture compared to those without diabetes, while African Americans with diabetes have little to no additional fracture risk, according to a study to be presented Saturday, March 23 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Key evidence associating hydrophobicity with effective acid catalysis
Researchers from Tokyo Metropolitan University have shown that the tunable hydrophobic nature of dense siloxane gels is strongly correlated with their catalytic activity, explicitly demonstrating how molecules with different hydrophobic nature at the molecular level interact differently with surfaces of differing hydrophobicity.
Breast cancer may be likelier to spread to bone with nighttime dim-light exposure
Exposure to dim light at night, which is common in today's lifestyle, may contribute to the spread of breast cancer to the bones, researchers have shown for the first time in an animal study.
Levothyroxine treatment in women with thyroid antibodies may not increase live birth rate
Treating women with thyroid antibodies but a normal thyroid function with a medicine called Levothyroxine does not make them more likely to deliver a live baby, new research suggests.
Breakthrough in air purification with a catalyst that works at room temperature
Researchers from Tokyo Metropolitan University have shown that a newly engineered catalyst made of gold nanoparticles supported on a metal oxide framework shows breakdown of ammonia impurities in air, with excellent selectivity for conversion to nitrogen gas.
Treating diabetes in older adults requires simpler medication regimens, looser glycemic targets
Simplifying medication regimens and tailoring glycemic targets in older adults with diabetes improves adherence and avoids treatment-related complications, according to a Clinical Practice Guideline issued today by the Endocrine Society.
Bisphosphonates increasingly prescribed to the women most likely to benefit
In recent years, women who start taking bisphosphonates (BPs) to treat osteoporosis and prevent fracture have trended from younger to older and from having osteopenia to having osteoporosis, researchers report.
Sperm DNA damage may contribute to repeat miscarriages
Some cases of recurrent pregnancy loss may be caused by sperm DNA damage in the male partner, rather than by a problem in affected women, according to research to be presented Sunday, March 24 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
New hybrid closed loop insulin pump proves hard to use for some patients with diabetes
Among first-time users of a new insulin pump that automatically delivers insulin to people with type 1 diabetes, nearly one-fifth stopped using the device, primarily because of difficulties meeting the technical demands system, researchers say.
A1c test misses many cases of diabetes
Using the hemoglobin A1c blood test to diagnose diabetes tends to underestimate the prevalence of the disease, according to a new study to be presented Saturday, March 23 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Eating later in the day may be associated with obesity
Eating later in the day may contribute to weight gain, according to a new study to be presented Saturday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Ovary function is preserved in transgender men at one year of testosterone therapy
Transgender men preserve their fertility potential even after one year of treatment with the male hormone testosterone, according to a study that will be presented Saturday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Improved PCOS symptoms correlate with gut bacterial composition
Symptoms of polycystic ovary syndrome (PCOS) improved with exposure to healthy bacteria in the gut, according to a study in a mouse model of this common women's endocrine disorder.
Older adults with type 1 diabetes often not aware of hypoglycemia
Older adults with type 1 diabetes typically have low blood sugar, or hypoglycemia, for more than an hour a day, suggests research to be presented Monday, March 25, at ENDO 2019, the annual meeting of the Endocrine Society, in New Orleans, La.

Rapid magnetic 3D printing of human cells
A team of McMaster University engineers has found a way to use 3D printing technology to create artificial tumours to help researchers test new drugs and therapies, which could lead to personalized medicine.

Now Playing: TED Radio Hour

Anthropomorphic
Do animals grieve? Do they have language or consciousness? For a long time, scientists resisted the urge to look for human qualities in animals. This hour, TED speakers explore how that is changing. Guests include biological anthropologist Barbara King, dolphin researcher Denise Herzing, primatologist Frans de Waal, and ecologist Carl Safina.

#SB2 2019 Science Birthday Minisode: Mary Golda Ross
Our second annual Science Birthday is here, and this year we celebrate the wonderful Mary Golda Ross, born 9 August 1908. She died in 2008 at age 99, but left a lasting mark on the science of rocketry and space exploration as an early woman in engineering, and one of the first Native Americans in engineering. Join Rachelle and Bethany for this very special birthday minisode celebrating Mary and her achievements. Thanks to our Patreons who make this show possible! Read more about Mary G.
