Scientists have developed a new analysis method that uses magnetic fields to quickly and accurately measure the concentration of aluminum used to purify tap water. These findings can potentially be used in developing efficient and environmentally-conscious coagulants for water treatment.
Last month, the atmospheric concentration of carbon dioxide (CO2) as measured at Amsterdam Island, in the southern Indian Ocean, for the first time exceeded the symbolic value of 400 ppm, or 0.04%. The CO2 concentrations recorded at the Amsterdam Island research station are the lowest in the world (excluding seasonal cycles), due to the island's remoteness from anthropogenic sources. The 400 ppm threshold was already crossed in the Northern hemisphere during the 2012/2013 winter. In addition, the increase of CO2 in the atmosphere is speeding up, growing by more than 2 ppm annually over the past four years.
Parents may have high expectations of their children’s academic performance and some may demonstrate this by urging the child to achieve good grades, while others may over-react when the child makes mistakes. However, parents should be mindful of their behavior and not push their children too far, as their actions may lead to unintended consequences.
Even though dense breast tissue is a risk factor for breast cancer, very low mammographic breast density is associated with a worse prognosis in breast cancer patients. Patient survival is affected only when low breast density is combined with an abundance of hyaluronan in the tumor, shows recent research.
Cleaning up space junk is a high priority for space agencies who have to operate at orbits that can come dangerously to it. The company SKA Polska won an ESA contract to design a prototype gun to be tested on parabolic flights.
A shorter course of prostate cancer radiotherapy, involving fewer hospital visits and higher individual doses of radiotherapy, is as effective as the current standard treatment for both survival and quality of life, a major new study reports.
It takes children until they are about 5 years old to learn to take turns with others, while the social skill seems to elude chimpanzees, according to new findings. The findings show that 5-year-old children adopted a turn-taking strategy more effectively than their younger counterparts, suggesting that the skill emerges as children's cognitive abilities mature.
Erioderma pedicellatum, commonly known as the Boreal felt lichen, grows on trees in the damp boreal forests along the Atlantic coast. It is also one of the most endangered lichens in the world. A new study uses population models to determine the survival and future viability of the species. The findings show that without increased protection and conservation efforts the Boreal felt lichen population in Nova Scotia will decline by 49 percent within 25 years.
New research is highlighting the potential merits of using precision medicine in prescribing antidepressants. Eleven percent of Americans 12 years and older have been prescribed antidepressant medication, according to Centers for Disease Control and Prevention data from 2005-2008. These medications are regularly prescribed in psychiatric, pediatric, adolescent, family and general medicine clinics nationwide.
An international team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high.
Fossil fuel combustion and associated air pollution and carbon dioxide has been identified as the root cause of much of the ill health of children today. Because of their inherent biological vulnerability, children now bear a disproportionate burden of disease from both pollution and climate change.
An anonymous reader quotes a report from Reuters: U.S. Senate Majority Leader Mitch McConnell set up a vote late on Monday to expand the FBI's authority to use a secretive surveillance order without a warrant to include email metadata and some browsing history information. The move, made via an amendment to a criminal justice appropriations bill, is an effort by Senate Republicans to respond to last week's mass shooting in an Orlando nightclub after a series of measures to restrict guns offered by both parties failed on Monday. Privacy advocates denounced the effort, saying it seeks to exploit a mass shooting in order to expand the government's digital spying powers. The amendment would broaden the FBI's authority to use so-called National Security Letters to include electronic communications transaction records such as time stamps of emails and the emails' senders and recipients. NSLs do not require a warrant and are almost always accompanied by a gag order preventing the service provider from sharing the request with a targeted user. The amendment filed Monday would also make permanent a provision of the USA Patriot Act that allows the intelligence community to conduct surveillance on "lone wolf" suspects who do not have confirmed ties to a foreign terrorist group. A vote is expected no later than Wednesday, McConnell's office said. Last week, FBI Director James Comey said he is "highly confident that [the Orlando shooter] was radicalized at least in part through the internet."
