The downside to solar and wind is not just low efficiency and high cost, it is also that they are intermittent. But that impacts cost also. Relying on them has meant contracting with traditional energy companies to be 'on demand' at far higher cost than they otherwise would be, to be on call to shut off or add electricity as needed. 

Wind will never be a serious alternative but solar is the future. Yet no matter how good solar becomes, there will still be a problem of storage and riding out its fluctuations - and existing storage capacities are far from adequate for the purpose.

Global warming is currently taking a break. Global temperatures seemed to have risen drastically into the late 1990s but the global average temperature has risen only slightly since 1998 – surprising, considering scientific climate models predicted considerable warming due to rising greenhouse gas emissions. In 2006, former U.S. Vice-President Al Gore said by 2016 it would be too late if we did not stop CO2 immediately.

Climate skeptics use this contradiction to question climate change as well as the validity of climate models. Meanwhile, the majority of climate researchers continued to emphasize that a short-term 'warming hiatus' can largely be explained on the basis of current scientific understanding and did not contradict longer term warming.

A new implantable tissue scaffold coated has been created, with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue.

Love and commitment make sex physically more satisfying for many women, according to Penn State Abington sociologist Beth Montemurro.

In interviews of 95 heterosexual women between the ages of 20 and 68 and from a range of backgrounds, most believed love was necessary for maximum satisfaction in both sexual relationships and marriage. The benefits of being in love with a sexual partner were more than just emotional, most of the women in the study said that love made sex physically more pleasurable. From September 2008 to July 2011, Montemurro conducted in-depth interviews with 95 women who lived in Pennsylvania, New Jersey and New York, lasting about 90 minutes each. 

The United States Supreme Court recently ruled against the Obama administration requirement that all employers must provide birth control insurance for women. Administration lawyers knew they were on shaky ground going in, because there were no provisions for male sex lives, such as Viagra, and that meant the policy was discriminatory, and the Supreme Court might rule that all corporations have the same rights, regardless of size, which further weakens the long-term viability of the ACA.

Schizophrenia is among the most severe forms of mental illness yet some people are as happy as those in good mental health and happier than many, according to a paper in Schizophrenia Research.

In a survey of people with the disease, researchers found that 37 percent of patients reported being happy all or most of the time.
