Pseudoscientific claims that music helps plants grow have been made for decades, despite evidence that is shaky at best. Yet new research suggests some flora may be capable of sensing sounds, such as the gurgle of water through a pipe or the buzzing of insects.
In a recent study, Monica Gagliano, an evolutionary biologist at the University of Western Australia, and her colleagues placed pea seedlings in pots shaped like an upside-down Y. One arm of each pot was placed in either a tray of water or a coiled plastic tube through which water flowed; the other arm had dry soil. The roots grew toward the arm of the pipe with the fluid, regardless of whether it was easily accessible or hidden inside the tubing. “They just knew the water was there, even if the only thing to detect was the sound of it flowing inside the pipe,” Gagliano says. Yet when the seedlings were given a choice between the water tube and some moistened soil, their roots favored the latter. She hypothesizes that these plants use sound waves to detect water at a distance but follow moisture gradients to home in on their target when it is closer.
The research, reported earlier this year in Oecologia, is not the first to suggest flora can detect and interpret sounds. A 2014 study showed the rock cress Arabidopsis can distinguish between caterpillar chewing sounds and wind vibrations – the plant produced more chemical toxins after “hearing” a recording of feeding insects. “We tend to underestimate plants because their responses are usually less visible to us. But leaves turn out to be extremely sensitive vibration detectors,” says lead study author Heidi M. Appel, an environmental scientist now at the University of Toledo.

The Healing Power of Music
What better “medicine” than a “treatment” that has only positive side effects and “therapy” that is actually enjoyable? Music is shown to have the ability to help organize the brain; especially vital to those who are afflicted with Alzheimer’s.
Studies have shown that the results of a musical therapy session last for several hours afterward. Positive results include elevated mood, increased socialization and appetite and reduction in agitation. These benefits are attributed to the stimulation the brain receives during a music therapy session, a sort of “cognitive workout”.
As speech, writing and traditional forms of communication are compromised, music provides an alternative means of maintaining a connection, thereby helping to normalize interaction between caregiver and patient. Music used therapeutically creates an environment where the patient can be nurtured and cared for in a way that is safe, gentle and appropriate. Music is central to maintaining human bonds when those with dementia have lost the ability to initiate communication or to respond verbally.
The powers of music when focused and used therapeutically are many. Critical to maintaining quality of life for those with Alzheimer’s is management of emotions and preserving the connection with others. Music is conducive to keeping those connections strong as long as possible while helping the participant to focus, increase awareness and orient to the environment. A number of research studies have looked at music therapy as an important adjunct to medical treatment and findings suggest a possible link between the use of music and slowing the progression of dementia.
Music is primal to life and expressed by each of us every day whether through dancing to a favorite tune, keeping rhythm with a pencil or remembering a special time when hearing a forgotten melody. It is central to our lives and is embedded in our culture, defining how we acknowledge milestones, rites of passage and celebrations as well as providing comfort, transformation and inspiration.

Abstract
Skipping breakfast can be potentially harmful because breakfast consumption is considered one of the important health-related behaviors that benefit physical and mental health. As the rate of depression has increased recently, we investigated the association between the frequency of eating breakfast and depression in adults. We obtained the data from the 2013 Korean Community Health Survey; a total of 207,710 survey participants aged 20 years or over were studied. Participants were categorized into three groups by the frequency of breakfast consumption as follows: “seldom,” “sometimes,” and “always.” We performed a multiple logistic regression to investigate the association between breakfast consumption and depressive mood. Subgroup analyses were conducted by stratifying socioeconomic variables controlling for variables known to be associated with depressive symptoms. Participants who had breakfast seldom or sometimes had higher depressive symptoms than those who always ate breakfast (“seldom”: OR = 1.43, 95% CI 1.36–1.52; “sometimes”: OR = 1.32, 95% CI 1.23–1.40). Subgroup analyses showed that this association was more marked in those who were 80 years or older, those who had low household income, or those with elementary school education level or less. The result of this study suggests that lack of breakfast consumption is associated with depression among adults with different socioeconomic factors.

Yellow Fever — Once Again on the Radar Screen in the Americas
Over the past several weeks, a fifth arbovirus, yellow fever virus, has broken out in Brazil, with the majority of the infections occurring in rural areas of the country. These are referred to as sylvatic, or jungle, cases, since the typical transmission cycle occurs between forest mosquitoes and forest-dwelling nonhuman primates, with humans serving only as incidental hosts. In this ongoing outbreak, health authorities have reported 234 confirmed infections and 80 confirmed deaths as of February 2017. Confirmed infections have occurred in the Brazilian states of Minas Gerais, Espírito Santo, and São Paulo, and hundreds of additional cases remain under investigation. The high number of cases is out of proportion to the number reported in a typical year in these areas.
Although there is currently no evidence that human-tohuman transmission through Aedes aegypti mosquitoes (urban transmission) has occurred, the outbreak is affecting areas in close proximity to major urban centers where yellow fever vaccine is not routinely administered. This proximity raises concern that, for the first time in decades, urban transmission of yellow fever will occur in Brazil.
Yellow fever is the most severe arbovirus ever to circulate in the Americas, and although vaccination campaigns and vector-control efforts have eliminated it from many areas, sylvatic transmission cycles continue to occur in endemic tropical regions. The most recent outbreak in Brazil highlights this phenomenon. If the current outbreak leads to urban spread through A. aegypti mosquitoes, clinicians should adopt a high index of suspicion for yellow fever, particularly in travelers returning from affected regions. As with all potentially reemerging infectious diseases, public health awareness and preparedness are essential to prevent a resurgence of this historical threat.

In 2017 the protestant church is celebrating an important event: the 500th anniversary of the Reformation
The 500th Reformation anniversary also means a great deal to Heidelberg. The then capital of the Kurpfalz (the Electoral Palatinate) played an important role in the spreading of the new doctrine. On April 26, 1518, Martin Luther visited Heidelberg, residence of the Elector Princes. As in Wittenberg, he proclaimed his 95 theses and defended himself before the General Chapter of the Augustine monks at the famous Heidelberg Defense. The commemorative Luther plaque marks where the Augustine abbey once stood. In 1563 the famous Heidelberg Catechism was formulated, the most significant confessional document in the reformed Christian faith the world over.

Death of The Death Care Industry
Death is a dying industry with an economic phenomenon. As Americans perceived value of “traditional” funerals diminish, the cost of funerals have increased nearly 1,328% in just four decades. In 1960 the average cost of a funeral was $706 when only 3.56% of bodies were cremated. Today the average traditional funeral costs between $8,000 and $10,000, and about 42% of people are cremated. The US funeral industry accounts for about $20 billion in annual economic activity, with around 130,000 employees that make a living on the 1.5 million people that go to rest each year.
Many communities have turned a blind eye to what goes on inside funeral homes, as many people prefer not to know the ins and out of the business. In addition, grieving customers in need of funeral goods and services may not be in a healthy state of mind to make financial decisions. Grief has similar side effects of alcohol consumption, such as numbness, guilt, and depression, resulting in less alert and price sensitive customers. In addition, the funeral industry is somewhat taboo in the sense that communities in general don’t communicate with one another about what are acceptable practices in this industry.
Some funeral service providers have taken advantage of this by encouraging the lack of transparency in the industry, charging exorbitant prices for funeral goods and services and charging people who appear to be wealthy higher prices. After Jessica Mitford published The American Way of Death in 1963, to expose the abuses in the funeral industry, a groundswell of support for government intervention followed. Under President Ronald Reagan The Funeral Rule was first enacted to protect consumers from deceptive practices, but the rule has yet to put the nail in the coffin.
