New research shows that using the drug in adolescence increased the risk of suffering from depression in adulthood by 37%. The researchers were unable to prove whether cannabis use causes depression but confirmed there is a strong link between the two, adding that a developing brain is very vulnerable to the effects of the drug. Previous research has suggested that cannabis affects the levels of serotonin in the brain that influence mood as well as the part of the brain that rules over emotional thinking. The researchers stated that parents who think the use of cannabis is a normal part of growing up should be careful about teens using cannabis since their brains are still developing.

A new study suggests that mortality rates are lower in those American communities where there are more primary care physicians compared to those with fewer doctors. The study shows that each increase of 10 doctors per every 100,000 people was associated with an increase of 51.5 days in life expectancy. The researchers suggest that having a great supply of primary care physicians in a community increases the chances that people with diseases like cancer, high blood pressure, or cardiovascular diseases will get a timely diagnose before it's too late. However, the number of these professionals is declining, which makes the researchers highlight the need to attract more medical students to the field of primary care.

However, hog meat constitutes a quarter of all the meat eaten in Vietnam, which has a population of more than 30 million pigs. Authorities said that customers can still eat pork and there's no reason to boycott the industry over this outbreak since the disease has no effect on humans.

Interval training is a type of exercise that combines short bursts of intense physical activity with short rest periods, and a new study suggests that this type of training may have slightly better results than traditional training. The researchers state that the reason for the effectiveness of this exercise is that the short periods of physical activity make the muscles burn more fat in the next 24 hours after the training session. The researchers added that one of the essential aspects of exercise is how the body reacts to the activity in the hours and days after exercising.

According to a new study, most knee and hip replacements last as long as 25 years, much longer than what researchers believed. According to the researchers from the University of Bristol, this finding will help doctors provide a time frame for its patients and choose the right time to have surgery. Before this study, specialists were only able to say how long the replacements are designed to last, instead of having concrete evidence, the researchers added that new replacements could last even longer due to the advancements in science and technology. Arthritic patients don't have to wait to the last minute to get surgery since now can get it much earlier and be confident that it will last.

For a long time, parents have opted to delay interventions for fears that general anesthesia may impair the cognitive development of the infant. However, a new study shows that general anesthesia might be as safe as regional anesthesia for a brief period. The researchers randomly assigned the two types of anesthesia to more than 700 infants set to receive surgery; then at the age of five, they tested the infants for IQ, behavior, executive function, and memory. The researchers found that the test scores were very similar between the two groups, though they warned that the effects of anesthesia are uncertain for longer periods, they added that most procedures usually take less than an hour for babies.

New research shows that almost half of women and a quarter of men leave their jobs in science, technology, engineering, and math after starting a family. The study shows that 23% of men and 43% of women leave their jobs when they become parents, which contributes to the great deficit of STEM professionals in the U.S. Researchers believe that an important factor is how the scientific community has made these people, especially women, feel that parenthood and STEM fields don't go together, pushing many women to find jobs that are more suitable for family life such as management or marketing. Another factor is that many companies offer lousy leave policy for new parents, pushing people to quit their jobs.

A new study shows that suicide is more common in states with higher gun ownership rates. The research from Boston University shows that in the 10 states with the highest rates of youth suicide, 53% of households owned a gun, while in the 10 states with the lowest suicide rates, only 20% of households have guns. However, gun ownership doesn't necessarily mean that the suicides were by firearm, but researchers consider that higher suicide rates have to do with the availability of highly lethal means to commit suicide.

A new study shows that opioid prescriptions for pets in the U.S. have surged by 41% in the last decade even though hospital visits have only increased by 13%. Researchers state that there's no way to prove whether these opioids end up being used by the owners, but they acknowledge the risk that the leftover opioids end up in the medicine cabinet accessible to children and other members of the family. Another factor that might contribute to the opioid crisis is that many states in the country don't require the same regulations for vet prescriptions as they do for regular doctors, making it easier for drug addicts to access these drugs.

The World Health Organization has said in a statement that an entire generation is at risk of hearing loss just by doing what they enjoy the most, listening to loud music on their phones. According to WHO, there are 466 million people worldwide with debilitating hearing loss, an increase from 360 million in 2010 and the current figure is expected to double by 2050 with nearly 900 million people. The organization urges officials and manufacturers to regulate the maximum level of volume on their devices; it has also asked for the introduction of software that can limit the decibels, as well as parental control for parents to take care of their children.

Lyme disease is transmitted by tick bites, and although it can be diagnosed with a blood test, the results may not be conclusive until after 8 weeks from the initial bite. However, now specialists are recommending to look for a distinctive "bull's eye" rash as a certain indication that a patient has Lyme disease. Officials in the UK say that if a patient has a rash, then it's a clear symptom that they are infected and must start treatment as soon as possible without waiting for a blood test. Lyme disease can be difficult to spot because its symptoms are similar to many other conditions, but if left untreated, can lead to heart and nerve problems.

Women in the UK have become more interested in an unusual hobby to fend off menopause, an activity that most of us wouldn't dare to do in our prime. Women going through menopause have found solace in cold-water swimming, an activity they claim has renewed their strength and has helped them fight against symptoms like depression. Scientists, however, are not sure why cold water is beneficial for these women, though some believe that this activity involves social interaction and exercise, two factors that can contribute to long-term health. Scientists also say that cold water triggers a hormonal fight-or-flight response in the body, which makes participants feel euphoric, but there aren't many studies on the matter.
