Parrots are not just mimicking words—they use proper names like humans to identify individuals
Analysis of vocalizations from over 880 captive parrots indicates that many parrots use names as labels to identify specific individuals, similar to human naming practices. Some parrots applied names to single individuals, while others used names for attention or in non-human-like ways. These findings suggest parrots possess cognitive and vocal abilities for flexible name use, though usage varies across species and individuals.

How long does a transplanted heart last?

The average lifespan of a transplanted heart is approximately 10 years, though individual outcomes vary. Key factors influencing longevity include careful post-surgical monitoring, strict medication adherence, management of comorbidities, and maintaining a heart-healthy lifestyle. Multidisciplinary care and strong social support further improve recovery and long-term health.
Patients can take steps to reduce complication risk and support long-term heart health, including:

Managing comorbidities, like diabetes or high blood pressure
Taking all medications as prescribed
Attending follow-up appointments with specialists
Maintaining a doctor-recommended, heart-healthy lifestyle

Abdominal fat is linked to a higher risk of urinary incontinence in women

Stress urinary incontinence is characterized by involuntary urine leakage during everyday activities such as coughing, laughing, lifting heavy objects, or exercising. It's that urinary leakage that occurs when pressure inside the abdomen increases and the pelvic floor can't hold it in.
Although the condition is often associated solely with aging, it is not exclusive to older women. It happens to women of all ages, including very young women. These pelvic floor muscles are rarely exercised throughout life, and without proper training, they can become weak and lose function.

Higher amounts of abdominal, particularly visceral, fat are strongly associated with increased risk of stress urinary incontinence in women, independent of total body fat or BMI. Visceral fat may contribute through mechanical pressure on the pelvic floor and metabolic effects such as chronic inflammation, potentially weakening pelvic floor muscles. Pelvic floor muscle training remains the primary treatment.
The accumulation of fat in the abdominal region, especially visceral fat (fat that accumulates between organs), significantly increases the risk of stress urinary incontinence in women. A study conducted at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, identified this region as the one most strongly associated with involuntary urine leakage, surpassing total body fat. The results are published in the European Journal of Obstetrics & Gynecology and Reproductive Biology and indicate that body fat distribution may be a more decisive factor than weight itself in explaining the condition.

The study results showed that women with higher amounts of body fat were more likely to experience incontinence. However, the main finding was the role of visceral fat. The presence of this type of fat increased the likelihood of stress urinary incontinence by about 51%.
There are two possible explanations. The first is mechanical. As visceral fat accumulates within the abdominal cavity, it increases pressure on the internal organs and overloads the pelvic floor, which is the structure responsible for supporting the bladder and controlling urine flow. Excess weight in this region creates constant strain. Over time, these muscles can become more fatigued and less efficient, the researchers explain.
The second mechanism is metabolic. Visceral fat does not merely function as an energy store; it is metabolically active and releases inflammatory substances that circulate throughout the body. This process can compromise muscle quality and reduce contractile capacity, including that of the pelvic floor muscles. It is low-grade chronic inflammation, which affects different tissues in the body. That can also contribute to muscle weakness.
Obesity is already recognized as a risk factor for urinary incontinence, along with aging, menopause, the number of pregnancies, and delivery conditions.
One of the main forms of treatment is strengthening the pelvic floor muscles through women's health physical therapy.
