Pitt con is the world's leading annual conference and exposition on laboratory science, keeping the scientific community connected to significant ongoing developments and new instrumentation. It attracts attendees from industry, academia and government from over 90 countries worldwide. Rigaku provides the world's most complete line of X-ray analytical instruments and will be exhibiting their diverse line of X-ray diffraction, X-ray fluorescence and handheld Raman and  LIBS instrumentation at the conference together at booth number 3151.

Heart Guidelines Rarely Backed by Good Science

Heart Guidelines Rarely Backed by Good Science

Friday, March 15, 2019 Precious few treatment guidelines for heart patients are supported by the best scientific evidence, a new study shows.

Less than one in 10 recommendations are based on results from multiple randomized controlled trails and that percentage has actually dropped in the past decade, the researchers reported.

For the study, the investigators analyzed the evidence behind more than 6,300 treatment recommendations for managing heart-related conditions-- such as high blood pressure and high cholesterol from the American College of Cardiology and the American Heart Association.

The recommendations are categorized by the amount of evidence supporting them. Level A means evidence came from multiple randomized controlled trials. Level B means that  evidence came from a single randomized controlled trial or observational studies and Level C means the recommendation is based only on expert opinion.

Major corridor of Silk Road already home to high mountain herders over 4,000 years ago 

Using ancient proteins and DNA recovered from tiny pieces of animal bone, archaeologists at the Max Planck Institute for the Science of Human History and the Institute of Archaeology and Ethnography at the Russian Academy of Sciences Siberia have discovered evidence that domestic animals cattle, sheep, and goat made their way into the high mountain corridors of southern Kyrgyzstan more than four millennia ago, as published in a study in PLOS ONE.

New surprises from Jupiter and Saturn

New surprises from Jupiter and Saturn

The latest data sent back by the Juno and Cassini spacecraft from giant gas planets Jupiter and Saturn have challenged a lot of current theories about how planets in our solar system form and behave.

The detailed magnetic and gravity data have been "invaluable but also confounding," said David Stevenson from Cal-tech, who will present an update of both missions this week at the 2019 American Physical Society March Meeting in Boston.

"Although there are puzzles yet to be explained, this is already clarifying some of our ideas about how planets form, how they make magnetic fields and how the winds blow," Stevenson said.

Study Suggests Prospect of Recent Underground Volcanism on Mars

Researchers argue there needs to be an underground source of heat for liquid water to exist underneath the planet's south polar ice cap, as predicted by a previous study.

The Martian South Pole. A new study in Geophysical Research Letters argues there needs to be an underground source of heat for liquid water to exist underneath the polar ice cap.

A study published  last year in the journal Science suggested liquid  water is present beneath the south polar ice cap of Mars. Now, a new study in the journal Geophysical Research Letters argues there needs to be an underground source of heat for liquid water to exist underneath the polar ice cap.

The new research does not take sides as to whether the liquid water exists. Instead, the authors suggest recent magmatic activity- the formation of a magma chamber within the past few hundred thousand years - must have occurred underneath the surface of Mars for there to be enough heat to produce liquid water underneath the kilometer and a half thick ice cap.  On the flip side,the study's authors argue that if there was not recent magmatic activity underneath the surface of Mars, then there is not likely liquid water underneath the ice cap.

This re writable paper depends on disappearing ink

Have you ever  made a mistake on something you printed from a computer? That paper probably went right into the recycling bin. Now you can erase your mistake and reuse that first sheet of paper. Scientists at Fijian Normal University in Fuzhou, China, coated one side of a regular sheet of printer paper with a heat-sensitive ink. A heated pen or printer makes the ink's blue color disappear, revealing the white paper below. To fix any errors, put the paper in the freezer and the ink will turn blue again. Words and pictures can remain visible on the paper for at least six months.

Influential initiative updates approach for assessing if corporate carbon targets are in line with 1.5 C and well below 2 C' warming goals

Corporate striving for 'best in class' sustainability strategies will have to meet tougher criteria to gain approval from the Science-Based Targets Initiative.

The body, which  independently assesses corporate carbon reduction targets to ensure they are in line with the goals set out in the Paris Agreement, said yesterday it had updated its materials for 1.5 C targets to bring them in line with the latest guidance from the landmark report last year.

The October paper made headlines around the  world for its stark assessment of the severe impacts more than 1.5 C of warming would have is to be any chance of avoiding higher levels of warming.
