The United States ranked in the bottom four of a United Nations report on child well-being. Among 29 countries, America landed second from the bottom in child poverty and held a similarly dismal position when it came to ‘child life satisfaction.
Lighting company Philips has developed an LED lamp that it describes as ‘the world’s most energy-efficient’.
It said the prototype tube lighting LED is twice as efficient as those currently used in offices and industry around the world but offers the same amount of light.
Being able to halve the amount of energy used could bring huge cost and energy savings.
Lighting accounts for more than 19% of global electricity consumption.
The prototype tube lighting produces 200 lumens per watt (200lm/W) compared with 100lm/W for equivalent strip lighting and 15lm/W for traditional light bulbs.
Light-emitting diodes have been around for years.
Traditionally, they have been used as indicators on electrical devices, such as standby lights on TVs. This was because LEDs were available only in red, but recent advances mean that other colours are now available, and the light emitted is much brighter.
White light (used for general lighting) using LEDs can be created via a number of techniques. One example is mixing red, green and blue LEDs.
It is suggested that LEDs can last for up to 100,000 hours, compared with the 1,000 hours of traditional incandescent light bulbs and compact fluorescent lamps’ (CFLs) 15,000 hours.
The technology is also much more energy-efficient, using up to 90% less […]
Sen. James Inhofe (R-OK) on Wednesday explained that Al Gore and the United Nations get most of the blame for what he called a global warming ‘hoax,
By the time the nation confronted the unthinkable school massacre in Connecticut last December, Mother Jones’ groundbreaking investigation of mass shootings, launched the prior summer, had shown that mass gun violence in America was on the rise. The trend appeared to be no coincidence in light of the proliferation of guns and looser gun laws nationwide. One leading criminologist took issue with our criteria, arguing that mass shootings had not become more common. But now, research from an expert on criminal justice at Texas State University further shows that gun rampages in the United States have escalated.
The research, to be published in a book in July, confirms that:
Patients, their families, and physicians have been satisfied with a ‘death with dignity’ physician-assisted suicide program made available to terminal cancer patients at a Seattle clinic, clinicians there reported.
Among 114 patients who asked about the program at the Seattle Cancer Care Alliance, the outpatient clinic for the city’s major cancer treatment centers, 40 passed screening examinations and ultimately received lethal prescriptions for secobarbital, although only 24 actually took the drug, according to Elizabeth Trice Loggers, MD, PhD, and colleagues at the clinic and its affiliated centers.
‘Patients, caregivers, and family members have frequently expressed gratitude after the patient obtained the prescription, regardless of whether it was ever filled or ingested, typically referencing an important sense of control in an uncertain situation,’ the authors wrote in the April 11 issue of the New England Journal of Medicine.
‘Our Death with Dignity program both allows patients with cancer who wish to consider this option to do so within the context of their ongoing care and accommodates variation in clinicians’ willingness to participate,’ they added. ‘The program ensures that patients (and families) are aware of all the options for high-quality, end-of-life care, including palliative and hospice care, with the opportunity to have any concerns or […]
