Why Volcanoes Don’t Matter Much

Guest Post by Willis Eschenbach The word “forcing” is what is called a “term of art” in climate science. A term of art means a word that is used in a special or unusual sense in a particular field of science or other activity. This unusual meaning for the word may or may not be…

The perfect storm for environmentalists: GMO engineered rice reduces greenhouse gas emissions to near zero

From the DOE/PACIFIC NORTHWEST NATIONAL LABORATORY and the “you can hear green heads exploding” department comes this bit of news sure to short circuit some people that are anti GMO but think the planet is doomed unless we do something about the threat of greenhouse gas emissions. Tiny grains of rice hold big promise for greenhouse…

ESO: "An Entire Spiral Galaxy Fell Through the Center of Massive Elliptical Galaxy M87"

"We are witnessing a single recent accretion event where a medium-sized galaxy fell through the center of Messier 87, and as a consequence of the enormous gravitational tidal forces, its stars are now scattered over a region that is 100...

Study of 'senior citizen' marine snails uncovered how nerve cells fail during learning

A new research study on marine snails uncovered the first cells in the nervous system to fail during aging. The researchers' findings are important to better understanding the underlying mechanisms of age-related memory loss in huma...

Researchers design first artificial ribosome

Researchers have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.

Can we restart the heart?

What if you could use the proliferative and survival properties of cancer-prone cells to rejuvenate cardiac progenitor cells and get them dividing again, without forming tumors? Researchers are exploring the results of taking an enzyme,...Show More Summary

Prostate cancer is five different diseases, experts say

Scientists have, for the first time, identified that there are five distinct types of prostate cancer and have found a way to distinguish between them, according to a landmark study.

Targeted therapy shows effectiveness against a subtype of the brain tumor medulloblastoma

A subset of medulloblastoma tumors briefly stopped growing or disappeared entirely during treatment with vismodegib, researchers report after a trial with both adults and children.

Meet the high-performance single-molecule diode

Researchers have created the world's highest-performance single-molecule diode. Development of a functional single-molecule diode is a major pursuit of the electronics industry.

Playing 'tag' with pollution lets scientists see who's 'it'

Using a climate model that can tag sources of soot and track where it lands, researchers have determined which areas around the Tibetan Plateau contribute the most soot -- and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes. Show More Summary

New research opens the door for treatment of relapsing bacterial infections

A new discovery could put people with relapsing urinary tract infections (UTIs) on the fast track for a new therapeutic regimen. An estimated 150 million UTIs occur each year worldwide, accounting for $6 billion in healthcare costs, according to the American Urological Association.

State immunization laws should eliminate non-medical exemptions, say internists

Support for eliminating existing exemptions, except for medical reasons, from immunization laws was among the policy recommendations adopted at the summer meeting of the Board of Regents of the American College of Physicians.

Researchers illuminate key role of NOX proteins in liver disease

A direct connection between two signaling proteins and liver fibrosis, a scarring process underlying chronic liver disease, the 12th leading cause of death in the United States, has been demonstrated by researchers.

Science educators analyze genetics content of Next Generation Science Standards

The genetics content of the Next Generation Science Standards -- a recent set of performance-based expectations for elementary, middle, and high school students in science classes -- represents, on average, a modest improvement over state standards, but is missing core genetics concepts and is difficult to interpret, according to research.

Evolutionary link between diet, stomach acidity

An analysis of data on stomach acidity and diet in birds and mammals suggests that high levels of stomach acidity developed not to help animals break down food, but to defend animals against food poisoning. The work raises interesting...Show More Summary

Bioethicists call for end to 'pay-to-play' clinical research

Charging people to participate in research studies is likely to undermine the fundamental ethical basis of clinical research, according to a new paper written by bioethicists. The paper outlines the arguments for and against the concept of "pay-to-play" research, ultimately concluding that this type of approach compromises the overall integrity of clinical research.
