The proteins PCH1 and PCHL help plants adapt to their surroundings. Plants react sensitively to changes in their surroundings and possess the ability to adapt to them. They use the photoreceptor protein phytochrome B to see light and then regulate processes such as seed germination, seedling development, longitudinal growth and flower formation.
Millions of pages of internal corporate and trade association documents relating to the introduction of new products and chemicals into the workplace and commerce have been compiled into a free searchable online database called ToxicDocs.
According to a national register study comparing Finnish birth cohorts from 1987 and 1997, an increasing number of adolescents receive a psychiatric or neurodevelopmental diagnosis. The number of diagnosed adolescents increased especially for girls in the younger cohort.
Researchers have discovered that the risk of death from breast cancer is twice as high for patients with high heterogeneity of the estrogen receptor within the same tumor as compared to patients with low heterogeneity. The study shows that the higher risk of death is independent of other known tumor markers and also holds true for Luminal A breast cancer.
A new study has examined how light pollution lures birds into urban areas during fall migration, a trend that poses risk for the fowl that often fly into buildings and has increased with the addition of brighter LED lights. The researchers were interested in seeing what factors shape the birds' distributions and why they occur in certain areas.
Scientists have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories.
More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater, which, under current state regulations, can still be treated and discharged into streams.
Researchers created a new synthetic virus that could lead to the development of a more effective vaccine against smallpox. The discovery demonstrates how techniques based on the use of synthetic DNA can be used to advance public health measures.
Cystic fibrosis shortens life by making the lungs prone to repeated bacterial infections and inflammation. Researchers have now shown for the first time that the lungs' bacterial population changes in the first few years of life as respiratory infections and inflammation set in. This research offers a way to predict the onset of lung disease in children with CF and suggests a larger role for preventive therapies, such as hypertonic saline.
The success of Pokémon GO made many people familiar with the concept of 'augmented reality': computer-generated perception blends into the real and virtual worlds. So far, these apps largely used optical methods for motion detection. Physicists have now developed an ultrathin electronic magnetic sensor that can be worn on skin. Just by interacting with magnetic fields, the device enables a touchless manipulation of virtual and physical objects.
Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers. They do this with the aid of hundreds of membrane proteins that sense microbes or other stresses. Researchers now have created the first network map for 200 of these proteins. The map shows how a few key proteins act as master nodes critical for network integrity, and the map also reveals unknown interactions.
Researchers have developed hardware that uses electric fields to move droplets of chemical or biological solutions around a surface, mixing them in ways that could be used to test thousands of reactions in parallel.
The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals.
More than 700,000 Americans were hospitalized due to illnesses associated with the seasonal flu during the 2014-15 flu season, according to federal estimates. A radical new approach to vaccine development may help lower that figure for future flu seasons.
