Toyota, Grenoble set stage for test in ride-sharing

Toyota is testing ride-sharing. As simple as that may sound, the experiment indicates an innovative model for the future of urban transportation. The Grenoble metro area could turn out to be the trial stage for a new city system in mobility. The model, which gets under way next month, calls for electric vehicles connected to a public transport system; the result is a weave of route planning, reservations and drop-offs. Five partners are sharing the vision: the City of Grenoble, the Metro Area, French electricity company EDF, Toyota, and local car-sharing operator, Cité lib. How it will work: 70 Toyota cars with 27 charging stations will be available for city trips. The stations will be operated by Sodetrel, an affiliate of EDF. Grenoble riders will be under a pricing plan called "3, 2, 1 euros." Users can pick-up one of the 70 vehicles and drop it off at any station near their destination without having to return it to the origi! nal pickup point. They will only be charged for the ride.

A spray-on light show on four wheels: Darkside Scientific

Darkside Scientific recently drew a lot of gazes its way in its video release of a car treated to the company's electroluminescent paint called LumiLor. Electroluminescence (EL) is a characteristic of a material that enables it to emit light in response to an electrical field. The company site said that at subatomic level, the process behind electroluminescence is radiative recombination, also known as spontaneous emission. In radiative recombination, phosphorescent substances emit photons (light particles) in response to alternating electrical current. As Geek.com noted, a custom deployment of this kind of paint with some custom electronics allows different sections of painted areas to light up independently. Seeing what the company did to the car, one can easily imagine marketing opportunities for this path to eye-grabbing showmanship.

New knowledge of genes driving bladder cancer points to targeted treatments

The story of cancer care seems so simple: find the mutated gene that causes cancer and turn it off or fix it. But rarely does a single gene cause cancer. More often, many genes are altered together to drive the disease. So the challenge becomes sorting out which altered genes are the most to blame in which cancers. A collaborative study between researchers at the University of Colorado Cancer Center and the National Cancer Institute (NCI) published today in the journal Clinical Cancer Research takes an important step toward answering this question in bladder cancer.

Breaking down experiences into million parts may help explain consciousness

Take the screen on which you are reading this article. When you look at it, you see one complete scene, but you know that this scene is composed of millions of pixels that only come in three colours: red, blue and green. When you look out at the world, you see one integrated landscape, whole and complete. But what if like every other biological system, this conscious experience too has its basic building blocks? I ask this question because, despite decades of research, consciousness remains an unexplained phenomenon. Perhaps thinking of consciousness as being made of bits of awareness is the solution.

As kids get older, snacks get poorer

T-bet tackles hepatitis

A single protein may tip the balance between ridding the body of a dangerous virus and enduring life-long chronic infection, according to a report appearing in The Journal of Experimental Medicine.

Study finds young women involve parent in abortion when anticipating support

When an adolescent wants to terminate a pregnancy, how does she decide whether to talk to a parent? A recent study from the Section of Family Planning and Contraceptive Research at the University of Chicago found that pregnant teens will turn to parents and adults who are engaged in their lives and who will offer support, regardless of her pregnancy decision. Young women will avoid talking with parents who are less involved or may try to prevent them from seeking care.

The research is published online ahead of print in the Journal of Bacteriology.

Congenital and genetic heart disease screening recommendations for people 12-25

Healthcare professionals should include 14 key elements that can be used as a checklist for screening young people age 12-25 for congenital and genetic heart disease. If any of the elements are positive, further testing may be needed, but initial screening using electrocardiograms (ECG) to detect underlying genetic and congenital heart disease in this age group prior to employing this checklist, has not been shown to save lives, according to a joint American Heart Association/American College of Cardiology statement.

What's more effective: Generic or brand-name statins?

Statins are the most frequently prescribed drugs in the United States and are effective in reducing cardiovascular events. However, evidence suggests that patients do not always take these medications as prescribed and may not receive their full benefit. Researchers from Brigham and Women's Hospital (BWH), Harvard Medical School and CVS Health investigated whether the use of generic versus brand-name statins can play a role in medication adherence and whether or not this leads to improved health outcomes. They found that patients taking generic statins were more likely to adhere to their medication and also had a significantly lower rate of cardiovascular events and death. These findings are published in the Annals of Internal Medicine on September 15, 2014.

Scientists identify the master regulator of cells' heat shock response

Heat shock proteins protect the molecules in all human and animal cells with factors that regulate their production and work as thermostats. In new research published Sept. 16 in the journal eLife, scientists at NYU Langone Medical Center and elsewhere report for the first time that a protein called translation elongation factor eEF1A1 orchestrates the entire process of the heart shock response. By doing so, eEF1A1 supports overall protein homeostasis inside the cell, ensuring that it functions properly under various internal and external stress conditions. The researchers suggest that this finding could reveal a promising, new drug target for neurodegenerative diseases and cancer.

Long-term effects of childhood asthma influenced by socioeconomic status

According to the Centers for Disease Control and Prevention (CDC), approximately 6 percent of children younger than five have been diagnosed with asthma, the fastest-growing and most common chronic illness affecting children in the United States. Studies have shown that asthma is associated with attention and behavioral issues in children, yet little existing research examines how socioeconomic status may influence the ultimate effects of these difficulties. Now, an MU researcher has found that the overall outcomes for children with asthma are influenced by socioeconomic inequalities.

Researchers develop improved means of detecting mismatched DNA

Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA.

In April, a patent was filed for the compound for use in SMA.

EEG study findings reveal how fear is processed in the brain

An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain. Understanding how threat is processed in a normal brain versus one altered by PTSD is essential to developing effective interventions.

Certain form of baldness at age 45 linked to higher risk of aggressive prostate cancer

A new, large cohort analysis from the prospective Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial, indicates that men who had moderate baldness affecting both the front and the crown of their head at age 45 were at a 40% increased risk of developing aggressive prostate cancer (usually indicates a faster growing tumor resulting in poorer prognosis relative to non-aggressive prostate cancer) later in life, compared to men with no baldness. There was no significant link between other patterns of baldness and prostate cancer risk. The study, published September 15 in the Journal of Clinical Oncology, supports earlier research suggesting that male pattern baldness and prostate cancer may be linked.

Biology news

How an ancient vertebrate uses familiar tools to build a strange-looking head

If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire evolutionary history. Instead, the new way to figure out how animals evolved is to compare regulatory networks that control gene expression patterns, particularly embryonic ones, across species. An elegant study published in the September 14, 2014 advance online issue of Nature from the Stowers Institute for Medical Research shows just how humbling and exhilarating that pursuit can be.

'Femme fatale' emerald ash borer decoy lures and kills males

An international team of researchers has designed decoys that mimic female emerald ash borer beetles and successfully entice male emerald ash borers to land on them in an attempt to mate, only to be electrocuted and killed by high-voltage current.

Measuring modified protein structures

Swiss researchers have developed a new approach to measure proteins with structures that change. This could enable new diagnostic tools for the early recognition of neurodegenerative diseases to be developed.

New insights in survival strategies of bacteria

Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, for example during treatment with antibiotics. A biofilm is a bacterial community that is surrounded by a protective slime capsule consisting of sugar chains and "curli". Scientists at VIB and Vrije Universiteit Brussel have for the first time created a detailed three-dimensional image of the pores through which the curli building blocks cross the bacterial cell wall, a crucial step in the formation of the protective slime capsule.

Final pieces to the circadian clock puzzle found

Researchers at the UNC School of Medicine have discovered how two genes – Period and Cryptochrome – keep the circadian clocks in all human cells in time and in proper rhythm with the 24-hour day, as well as the seasons. The finding, published today in the journal Genes and Development, has implications for the development of drugs for various diseases such as cancers and diabetes, as well as conditions such as metabolic syndrome, insomnia, seasonal affective disorder, obesity, and even jetlag.

Proteins can be easily and sensitively detected by their scattered light

In future, some diseases might be diagnosed earlier and treated more effectively. Researchers at the Max Planck Institute for the Science of Light in Erlangen have developed an optical method that makes individual proteins, such as the proteins characteristic of some cancers, visible. Other methods that achieve this only work if the target biomolecules have first been labelled with fluorescent tags; In general, however, that approach is difficult or even impossible. By contrast, with their method, coined iSCAT, the researchers in Erlangen are able to directly detect the scattered light of individual proteins via their shadows. The method could not only make biomedical diagnoses more sensitive, but also provide new insights into fundamental biological processes.

Decoding virus-host interactions in the oxygen-starved ocean

For multicellular life—plants and animals—to thrive in the oceans, there must be enough dissolved oxygen in the water. In certain coastal areas, extreme oxygen-starvation produces "dead zones" that decimate marine fisheries and destroy food web structure. As dissolved oxygen levels decline, energy is increasingly diverted away from multicellular life into microbial community metabolism resulting in impacts on the ecology and biogeochemistry of the ocean.

Scientists discover tropical tree microbiome in Panama

Human skin and gut microbes influence processes from digestion to disease resistance. Despite the fact that tropical forests are the most biodiverse terrestrial ecosystems on the planet, more is known about belly-button bacteria than bacteria on trees in the tropics. Smithsonian scientists and colleagues working on Panama's Barro Colorado Island discovered that small leaf samples from a single tree were home to more than 400 different kinds of bacteria. The combined sample from 57 tree species contained more than 7,000 different kinds.

Scientists discover RNA modifications in some unexpected places

The so-called central dogma of molecular biology—that DNA makes RNA which makes protein—has long provided a simplified explanation for how genetic information is deciphered and translated in living organisms.

Timing clutch for greater sage-grouse

(Phys.org) —It's an oft-repeated phrase that the early bird gets the worm. And, according to a collaborative study between the University of Maine and University of Nevada, Reno, it's also true that a greater sage-grouse that lays her eggs earliest, lays the most eggs.

Mosses survive climate catastrophes

Mosses have existed on Earth for more than 400 million years. During this period they survived many climate catastrophes that wiped out more robust organisms such as, for example, dinosaurs. Recently, British scientists brought single moss plants back to life after they had been frozen in the Antarctic ice for 1,500 years. Why are these small plants so resilient to climate changes? The biologists Professor Ralf Reski and Professor Peter Beyer and their teams discovered that mosses have specific genes that are activated quickly at low temperatures.

Project prepares collection for 21st-century challenge of invasive species

UW-Madison sophomore Alex Idarraga carefully feeds a paper sheet holding a pressed, dried plant into a light box, closes the door and triggers the camera mounted overhead.

Think big: Bacteria breach cell division size limit

The life of a cell is straightforward: it doubles, divides in the middle and originates two identical daughter cells. Therefore, it has been long assumed that cells of the same kind are similarly sized and big cells cannot divide symmetrically. Silvia Bulgheresi's team, University of Vienna, revealed that two non-model bacteria divide regularly despite growing so long to be perceivable by the naked eye. These findings have been published in the renowned journal Nature Communications.

Study finds warming Atlantic temperatures could increase range of invasive species

"The results will allow us to better understand how the fish communities might shift under different climate change scenarios and provide the type of environmental data to inform future decisions relating to the management and siting of protected areas," said Paula Whitfield, a research ecologist at NOAA's National Centers for Coastal Ocean Science (NCCOS) and lead author of the study.

Tigers, pandas and people a recipe for conservation insight
