Transportation is a big cause of CO2 emissions so when pop star Will.i.am takes a helicopter to a climate event to tell everyone else to be more environmentally responsible, or when environmental journalists fly across the world to attend summits because their 'relationships' are too important to use a video conference, it doesn't inspire a lot of commoners to cut back.

Not that they did anyway. Most people rationalize travel, and simply cut back in ways they would anyway. 

A recent study evaluating HER2 testing in a large cohort of women with breast cancer found important limitations in the conventional way HER2 testing is performed in the US and internationally.

Dartmouth-Hitchcock Norris Cotton Cancer Center physicians and researchers retested tumor samples from a large group of women and found that 22 out of 530 women had their tumor type incorrectly classified. They reported their findings in a publication titled "Assessing the Discordance Rate between Local and Central HER2 Testing in Women with Locally Determined HER2-Negative Breast Cancer," which was published in Cancer on June 13, 2014.

CLEVELAND, Ohio (June 18, 2014)—Calcium and vitamin D are commonly recommended for older women, but the usual supplements may send calcium excretion and blood levels too high for some women, shows a new study published online today in Menopause, the journal of The North American Menopause Society.

This randomized, placebo-controlled trial included 163 older (ages 57 to 90) white women whose vitamin D levels were too low. The women took calcium citrate tablets to meet their recommended intake of 1,200 mg/day, and they took various doses of vitamin D, ranging from 400 to 4,800 IU/day. (The trial was limited by ethnicity because different ethnic groups metabolize calcium and vitamin D differently.)

More and more people are being diagnosed with diabetes and other hormone conditions and that is making a problem become obvious; there aren't going to be enough endocrinologists.

Endocrinologists are specially trained physicians who diagnose diseases related to the glands. They specialize in treating diabetes, obesity, osteoporosis, thyroid disorders, adrenal diseases, and a variety of other conditions related to hormones. But in America of the future, as the government gradually takes over health care, salaries for doctors are going down, not up, so it is not going to be easy to convince specialists to spend the time. A great doctor in the US Army makes the same money as an average supply officer of the same rank and time.

In the modern American political climate, we see echoes of 40 years ago, when Richard Nixon was president. Federal agencies are being used as hatchetmen for the administration, copies of messages mysteriously get lost when subpoenaed by Congress, and if anyone objects to domestic spying, we are told it's to stop terrorism.

Stopping terrorism seems to be an agreeable notion to people, that is why it has become a blanket excuse for all kinds of government conduct. 

And it has even become a way to use medical care.

A new analysis by Karolinska Institutet in Sweden found that drug therapy for ADHD does not entail an increased risk of suicide attempts or suicide. 

Other studies have found  that ADHD drug treatment would increase the occurrence of suicidal thoughts but the authors of the new paper in BMJ say those studies were too small scale and/or methodologically unsound, which make the results uncertain. For the new paper, the authors used national patient registers to identify all patients in Sweden diagnosed with ADHD between 1960 and 1996; a total of 37,936 individuals. These people were then followed over the period 2006-2009, in terms of drug treatment and events that could be linked to suicide attempts and suicide. 

Organisation for Economic Co‑operation and Developoment (OECD) countries that lead in innovation are easy to spot - you look for the ones that have the most scientists in the private sector. 

Countries like the United States, Korea and Japan are responsible for the bulk of the world's technology design and they have over 75% of researchers employed in the private sector. 

In other OECD countries, the numbers are much lower - scientists are instead government employees and the need for innovation is last. This worries Spain, where research and innovation lags. In OECD countries overall, only 45.4% of scientists work in the private sector, the rest are being funded by taxes rather than corporate profits. In Spain, it is half that.

20 year ago, some teens were always trying to get sex - and they talked about it. But their behavior was not stored in an NSA database somewhere.

If it were stored with the IRS, such discussions might be safe because they could be lost with a Nixon-ian phone call or two, but otherwise someone can find out about sexy talk in the modern age - "sexting". A new psychology paper surveyed college students (naturally) and found that more than 50 percent of those surveyed reported that they had exchanged sexually explicit text messages, with or without photographic images, as minors.

American children learn the meanings of number words gradually: First they understand "one," then they add "two, "three," and "four," in sequence. At that point, however, a dramatic shift in understanding takes place, and children grasp the meanings of not only "five" and "six," but all of the number words they know.

During evolutionary diversification of vertebrate limbs, the number of toes in even-toed ungulates such as cattle and pigs was reduced and transformed into paired hooves. Scientists at the University of Basel have identified a gene regulatory switch that was key to evolutionary adaption of limbs in ungulates.
