More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
Ever since the 1973 oil embargo, U.S. energy policy has sought to replace petroleum-based transportation fuels with alternatives. One prominent option is using biofuels, such as ethanol in place of gasoline and biodiesel instead of ordinary diesel.
Transportation generates one-fourth of U.S. greenhouse gas emissions, so addressing this sector’s impact is crucial for climate protection.
Researchers have developed a low-cost, portable laboratory on an iPhone 5 that can analyze several samples at once to catch a cancer biomarker, producing lab quality results.At a time when patients and medical professionals expect always faster results, researchers are trying to translate biodetection technologies used in laboratories to the field and clinic, so patients can get nearly instant diagnoses in a physician's office, an ambulance or the emergency room. The team created an eight channel smartphone spectrometer that can detect human interleukin-6 (IL-6), a known biomarker for lung, prostate, liver, breast and epithelial cancers. A spectrometer analyzes the amount and type of chemicals in a sample by measuring the light spectrum.
"Could you repeat that?" The reason you may have to say something twice when talking to older family members at Thanksgiving dinner may not be because of their hearing. Researchers at the University of Maryland have determined that something is going on in the brains of typical older adults that causes them to struggle to follow speech amidst background noise, even when their hearing would be considered normal on a clinical assessment.In the study, researchers Samira Anderson, Jonathan Z. Simon, and Alessandro Presacco found that adults aged 61-73 with normal hearing scored significantly worse on speech understanding in noisy environments than adults aged 18-30 with normal hearing.
New research suggests that "flash droughts", like the one that unexpectedly gripped the Southern Rockies and Midwest in the summer of 2012, could be predicted months in advance using soil moisture and snowpack data.Scientists at the National Center for Atmospheric Research (NCAR) analyzed the conditions leading up to the 2012 drought, which ultimately caused $30 billion in economic losses, looking for any warning signs that a drought was on the way. They find that observations of snowmelt and soil moisture could have predicted the ensuing drought up to four months in advance.
Researchers have found an association between migraines and microbes that reduce nitrates. Analyzing data from the American Gut Project, they found that migraine sufferers harbored significantly more microbes in their mouths and guts with the ability to modify nitrates compared to people who do not get migraine headaches.
By some estimates, about 2 billion tons of food, about 50 percent of all the food produced on the planet, is wasted before it ever reaches a human stomach.
That's bad, but science, like apples and potatoes that look more appealing for a longer time, can fix some of that, while better pesticides and scientific optimization can improve yields at the agriculture stage, if environmentalists would stop terrorizing people about food.
Yet a survey by the International Food Information Council (IFIC) Foundation finds something more worrisome now; many Americans are shockingly unaware of their own roles in contributing to the problem,.
The story of phosphoethanolamine (PHOS) in Brazil, which set off a widely publicized scientific debacle about the dangers of taking unproven compounds as medicines, shows once again that just because some miracle cure is touted in a foreign country doesn't make it real.This fact is in defiance of anti-science groups convinced of an FDA/Big Pharma conspiracy against cures, but America remains the gold standard for legitimacy, and with good reason. While cancer patients and their advocates may find the process of cancer drug discovery to be opaque or frustrating, the authors of the policy paper argue that the process is an essential part of clinical research.
In a recent paper, of 81 overweight and obese women with type 2 diabetes who usually consumed diet beverages and were on a weight loss program, those who substituted water for diet beverages after their lunch for 24 weeks had a greater decrease in weight (-6.40 vs. -5.25 kg) and body mass index (-2.49 vs.
A novel computational approach to design has created a new compound that in laboratory studies has reduced deficits and neurodegenerative symptoms that underlie Parkinson’s disease.In their study, the researchers describe how their compound, dubbed NPT100-18A, prevents the binding and accumulation of alpha-synuclein or α-syn in neuronal membranes, now considered a hallmark of Parkinson’s disease and a related disorder called dementia with Lewy bodies.
Researchers have demonstrated the ability to deliver a fully functional copy of the CLN3 gene to stem cells of patients with juvenile NCL, an inherited neurodegenerative disease in which a mutation in the CLN3 gene causes early-onset severe central vision loss. The gene therapy restored production of CLN3 protein in the stem cell-derived retinal neurons, as described in an article in Human Gene Therapy.
Invasive plants are a problem around the world, but are they just a nuisance or are they killers? So far there are no documented cases of native plants becoming extinct purely because of an alien plant invasion. However, researchers Paul Downey and David Richardson argue in a paper published this month in AoB PLANTS, 'Alien plant invasions and native plant extinctions: a six-threshold framework', that traditional methods of modelling extinction do not work well for plants. Focusing purely on extinction can distract plant conservationists from growing problems. Instead they propose six thresholds that species cross before they become extinct.
Chocolate or apple? Most people are in two minds when buying food: one motivation is to purchase whatever tastes best – so something that is generally sweet or fatty. At the same time, we know attention should be paid on health factors and, for instance, making sure we don’t consume too many calories. A new survey finds that if the packaging information also features food traffic light colors, fewer products are chosen purely based on taste and more based on health aspects compared with nutritional information purely in percentages and grams.
