Article Published to: www.nature.com Article number 1898.Written in a journal called Nature Communications. Scientists have discovered that the way we see plastic now, could be completely changed in the future.
Stephen T. Liddle who is the Professor of Head of Inorganic Chemistry and Author of the article has found that uranium could deteriorate in weeks/months, while the plastic we have today stays in landfills forever. Professor Liddle has also found that the way that uranium interacts with polymer and other chemicals may have offering properties that are yet to be discovered.
These interactions could be more ecologically efficient. The uranium may have interactions with certain chemicals, but it’s broken down materials may be radioactive, or more harsh then have plastic sit in a landfill.I think that this could be potentially a scientific breakthrough.
This could cut the amount of plastic thrown in landfills in half. The plastic being able to disintegrate itself could do the environment some good. If the deteriorated uranium causes radioactive waste being stored in the ground instead, that is another issue. That could harm our society more than the landfills itself do. This could be a great alternative to plastic, but may result in being more harmful than helpful.Summary Number 2 (Chemistry)Diabetes drug ‘significantly reverses memory loss’ in mice with Alzheimer’sDate Article was Published: January 1, 2018.Author: Christian Holscher, Professor at Lancaster University.Website found: www.

A drug originally created to treat Type 2 Diabetes, could potentially cure the Alzheimer’s disease. The drug has been tested on mice with the Alzheimer’s disease, and results show that through a triple method of action it ‘significantly reversed memory loss’.Dr. Doug Brown said how there haven’t been “No new treatments in nearly 15 years” this drug could cure the disease.
I personally know multiple people with the Alzheimer’s disease. I have seen first hand 7 how this disease can affect people. Not just the ones that are affected, but the family as well. This medicine could reverse the effects of Alzheimer’s in the 5.5 million Americans that have already been diagnosed with this disease. This discovery could impact the lives of the people that have Alzheimer’s and the 200 000 individuals aged 65 and under that have already been diagnosed with younger-onset Alzheimer’s.

Written in a journal called Nature Communications. The current work of ASD that changes in the genetic code of a particular gene can control epigenetic marks at different genes, implying that a gene’s genetic code can affect whether other genes are turned on and off, which makes it important to understand the function of all genes involved, not just the one with the so-called misspelling. To investigate this question, Fallin and her colleagues started by surveying four different tissue types, blood and cord blood from their own collections, as well as lung and fetal brain tissue from public collections, to find small variations in the genetic.Summary Number 4 (Biology)Earlier school start times may increase risk of adolescent depression and anxietyDate Article was Received: June 1, 2017.Date Article was Published: October 5, 2017.Author: Jack S.

are more likely to have depression and anxiety, even if they get a good night’s sleep, showed a study from Rochester, N.Y., suggests. University of Rochester researcher Jack Peltz, Ph.D., published an article that suggests the link between sleep and the mental health of youth, the article explains how school start times may have a negative effect on the amount of sleep yoth get and daily functioning.
The research provides evidence about how school start times impact teenage health. “Our study is consistent with a growing body of research demonstrating the close connection between sleep hygiene and adolescent mental health,” says Peltz. “But ours is the first to really look at how school start times affect sleep quality, even when a teen is doing everything else right to get a good night’s sleep.
While there are other variables that need to be explored, our findings show that earlier school start times seem to put more pressure on the sleep process and increase mental health symptoms, while later school start times appear to be a strong protective factor for teens.”Summary Number 5 (Electricity)The mere presence of your smartphone, reduces brain powerDate Article was Published: June 23, 2017Author: Adrian Ward, Professor at The University of Texas.Website found: www.
sciencedaily.com (Site in Layman’s terms)Published from: University of Texas News. Your cognitive capacity is significantly reduced when your smartphone is within reach — even if it’s off. That’s the takeaway finding from a new study from the McCombs School of Business at The University of Texas at Austin. McCombs Assistant Professor Adrian Ward and co-authors conducted experiments with nearly 800 smartphone users in an attempt to measure, for the first time, how well people can complete tasks when they have their smartphones nearby even when they’re not using them. In one experiment, the researchers asked study participants to sit at a computer and take a series of tests that required full concentration in order to score well. The tests were geared to measure participants’ available cognitive capacity — that is, the brain’s ability to hold and process data at any given time.Summary Number 6 (Electricity)Electricity produced from tearsDate Article was Published: October 2, 2017Author: Aimee Stapleton, Irish Research Council EMBARK Postgraduate Fellow in the Department of Physics and Bernal Institute of UL.
Website found: www.sciencedaily.comReport published from: Applied Physics Letters. A team of Irish scientists has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute, University of Limerick (UL), Ireland, observed that crystals of lysozyme, a model protein that is abundant in egg whites of birds as well as in the tears, saliva and milk of mammals can generate electricity when pressed.
They published an article on October 2 in the journal, Applied Physics Letters. The ability to generate electricity by applying pressure, known as direct piezoelectricity, is a property of materials such as quartz that can convert mechanical energy into electrical energy and vice versa. “While piezoelectricity is used all around us, the capacity to generate electricity from this particular protein had not been explored.
Crystals of lysozyme are easy to make from natural sources. According to team leader Professor Tofail Syed of UL’s Department of Physics, “Crystals are the gold-standard for measuring piezoelectricity in non-biological materials.” The discovery may have wide reaching applications and could lead to further research in the area of energy harvesting and flexible electronics for biomedical devices. Professor Luuk van der Wielen, Director of Bernal Institute and Bernal Professor of Biosystems Engineering and Design expressed his delight at this breakthrough by UL scientists. “The Bernal Institute has the ambition to impact the world on the basis of top science in an increasingly international context.
The impact of this discovery in the field of biological piezoelectricity will be huge and Bernal scientists are leading from the front the progress in this field,” said Luuk van der Wielen.
