If there were humans on the Moon - would we see the settlement lights from the Earth? For instance during a thin crescent Moon - could we see the lights of civilization in the parts of the Moon in darkness? 

It's a fun question to answer I think, so let's give it a go.

We can work it out backwards from the brightness of the full Moon.

Though activists want to retreat into the past and have less energy available for the public (which will impact the poor) a more progressive approach is to look to science and the future - but that will only work if there are stable policies in place.

Oddly, this progressive thinking is coming from energy corporations rather than environmentalists. A group of electricity corporations are creating a picture of a future high-tech energy mix that would help nations meet climate-related CO₂ reduction pledges and the expanding demand for electricity.

Children's self-esteem is linked to the behaviour of who is considered the most powerful parent within the household, new University of Sussex research suggests.

The study of English and Indian families living in Britain is the first to assess the impact on a child's wellbeing of the household power structures that exist within different cultures.

Psychologists interviewed 125 English and Indian families living in West London.

They found that English children whose mothers displayed more negative parenting traits - such as detachment, intrusiveness, lax enforcement of discipline, and controlling behaviour - reported lower self-esteem. But, for Indian children, the father's behaviour had more of an impact.

One of biology's long-standing puzzles is how so many similar species can co-exist in nature. Do they really all fulfill a different role? Massive data on beetles now provide strong evidence for the idea that evolution can drive species into groups of look-a-likes that are functionally similar, according to a study by an international consortium of scientists led by Wageningen University, Netherlands.

Cigarette smoking and heavy alcohol use cause epigenetic changes to DNA that reflect accelerated biological aging in distinct, measurable ways, according to research presented at the American Society of Human Genetics (ASHG) 2015 Annual Meeting in Baltimore.

The popularity of ziplining has skyrocketed rapidly in recent years. The number of commercial ziplines in the U.S. rose from 10 in 2001 to more than 200 in 2012, in addition to more than 13,000 amateur ziplines which can be found in outdoor education programs, camps, and backyards. The increase in popularity has also increased the number of injuries related to ziplining. A new study by researchers in the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital found that an estimated 16,850 non-fatal zipline-related injuries were treated in U.S. emergency departments from 1997 through 2012.

Although children with high health care needs represent a small percentage of the overall pediatric population, they account for a large percentage of pediatric health care costs, including up to 40% of pediatric hospital charges. In recent years, there has been more information available about the medical care received by these children, but generally studies have been limited to care provided in hospital settings.

Physicians' unconscious attitudes toward special patient populations like disabled and LGBT patients may be partially responsible for poorer overall health observed in these communities, according to a Rowan University professor of family medicine.

Physicians' reluctance to discuss disabilities, sex, work and independence with disabled patients, who comprise nearly 20 percent of Americans, deprives patients of high quality care by leaving important health concerns unaddressed, said Joshua Coren, DO. Primary care providers frequently fail to discuss contraception, sexually transmitted diseases, emotional health and basic wellness concerns like diet, exercise, smoking and alcohol use with patients who have disabilities, Dr. Coren added.

OK, so I'm a 62-year old moron. Like *you're* so perfect?  This probably explains why I couldn't pass on this one. 

The word "green" has become so ubiquitous that it has become a parody of itself. Everything is green! Especially the vast amounts of green paper, which portrays formers presidents. Which is the type of green that those who sell you green stuff are lining their pockets with. 

It has gone way past crazy. Like green garbage bags:

Although they claim that their bags are made from recycled Winnebagos, I'm suspicious.

New research suggests that upper limb amputees, who typically struggle to learn how to use a new prosthesis, would be more successful if fellow amputees taught them.

Most usually learn by watching a non-amputee demonstrate the device during physical therapy and rehabilitation sessions but a Georgia Institute of Technology study that measured arm movements and analyzed brain patterns found that people do better when they learn from someone who looks like them.
