In the 1980s, scientists captured the precise mechanics of a protein machine. It looked strange, to researchers its tall thin structure with stubby legs invoked the enchanted broomstick that stole the show in "The Sorcerer's Apprentice" segment of Disney's 1940 Fantasia film.

In many casual discussions of language and the internet, it’s not uncommon to hear about how such “textspeak ruins language” – how technology has made everybody lazy with their speech and writing. Major media outlets such as the LA Times, the BBC and The Daily Mail have all bemoaned the ways in which people communicate through technology.
Researchers have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. Natural metabolic pathways for the renewable biosynthesis of propane do not exist but scientists at the Manchester Institute of Biotechnology (MIB), Imperial College and University of Turku have developed an alternative microbial biosynthetic pathway to produce renewable propane.
Not all exoplanets are going to be habitable, many will be just the opposite. Astronomers have measured the temperature of the atmosphere of an exoplanet with unequaled precision and determined we won't be vacationing there any time soon. By crossing two approaches, using the HARPS spectrometer and a new way of interpreting sodium lines, researchers have been able to conclude that exoplanet HD 189733b is showing infernal atmospheric conditions, with wind speeds of more than 1,000 kilometers per hour and a temperature 3,000 degrees.
Researchers have discovered how nerve cells adjust to low energy environments during the brain's growth process, which may one day help find treatments for nerve cell damage and neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.Neurons in the brain have extraordinarily high energy demands due to complex dendrites that expand to high volume and surface areas. It is also known that neurons are the first to die from restriction of blood supply to tissues, causing a shortage of oxygen and glucose needed for cellular metabolism.
Human norovirus can cause an immune response in dogs so it leads to obvious concern over whether or not dogs can transmit it to other people.Norovirus, which causes vomiting and diarrhea, is extremely contagious among humans. It infects 19-21 million Americans annually - more than six percent of the US population - according to the CDC. Those infections may result in as many as 71,000 hospitalizations, and 800 deaths.
How fast the universe has been expanding since the Big Bang is something of a puzzling question. It wasn't that long enough that we didn't know it was accelerating at all, and a new study finds the acceleration of the expansion of the universe might not be as fast as thought.The currently accepted view of the universe expanding at a faster and faster rate, pulled apart by an unknown force labeled under the umbrella term 'dark energy', is based on observations that resulted in the 2011 Nobel Prize for Physics. But observations based on uniform type Ia supernovae - cosmic "beacons" - may actually fall into different populations. That's like comparing 100-watt light bulbs only to find out they vary in brightness.
Papain, found naturally in papaya and ioften referred to as a “plant-based pepsin”, is an important industrial protein-degrading enzyme for the food and cosmetic industries. The cosmetic industry uses papain in exfoliating treatments to remove dead surface skin and there even are enzyme-based shampoos for house pets to clean the fur and make it easier to brush. But lots of natural things can trigger allergic reactions.
For more than 50 years, people said that the "Pinocchio Lizard" (horned anole lizard), called such for its long, protruding nose, was extinct, but that was just a fib by nature.
In 2005, it was found living at the tops of tall trees in the cloud forests of Ecuador. Like many species that are considered rare or endangered, it is instead the case that there are not many of them and never have been, and they are limited to a small area.
Why the nose? Only the males have long noses, and they appear to be used in social interactions, both among males and between males and females. Previous investigators had wondered if the nasal appendage served as a weapon of some sort in male-male interactions.
Soil is considered e a semi-permanent storehouse for ancient carbon but it may instead be releasing carbon dioxide to the atmosphere faster than thought, which means that the carbon bomb not happening in one study could be happening in this other one published in Nature Climate Change.
In the paper, researchers showed that chemicals emitted by plant roots act on carbon that is bonded to minerals in the soil, breaking the bonds and exposing previously protected carbon to decomposition by microbes.
Sometimes guidelines cause people to be on medication who otherwise would not need to be. We have seen this concern due to runaway claims about the nebulous "pre-diabetes" diagnoses being discussed, and in commercials on television for prescription products to prevent anaphylaxis even though 0.05% of kids is ever going to be at risk and they are exploiting the allergy fad culture to make money.
A vital self-destruct switch in cells is hijacked - making some pancreatic and non small cell lung cancers more aggressive, according to new research which found that mutations in the KRAS gene interferes with protective self-destruct switches, known as TRAIL receptors, which usually help to kill potentially cancerous cells.
The research, carried out in cancer cells and mice, shows that in cancers with faulty versions of the KRAS gene these TRAIL receptors actually help the cancer cells to grow and spread to new areas in the body. These KRAS faults occur in 95 percent of pancreatic cancers - pancreatic ductal adenocarcinoma - and 30 percent of non small cell lung cancers.
African-American women who live in rural areas have lower rates of major depressive disorder (MDD) and mood disorder compared with their urban counterparts, while rural non-Hispanic European-American women have higher rates for both than their urban counterparts, according to a new study.
Major depressive disorder is a debilitating mental illness and the prevalence of depression among both African- and Rural-Americans is understudied, according to background in the study. Addie Weaver, Ph.D., of the University of Michigan, Ann Arbor, and coauthors examined the interaction of Urban-American vs.Rural-American residence and race/ethnicity on lifetime and 12-month MDD and mood disorder in African-American and non-Hispanic European-American women.
