Researchers at 缅北强奸 have discovered a new, more environmentally friendly way to make ketones, an important chemical ingredient in pharmaceuticals.听 While ketones are found in a wide range of useful chemicals, they are commonly prepared through energy-intensive, multi-step technologies that create significant chemical waste.听 In an article published online last month in Nature Chemistry, the 缅北强奸 scientists demonstrate how carbon monoxide, a widely available by-product of combustion, can instead be used to form high-energy chemicals that react directly with benzene to
More than 400,000 Canadians aged 65 and over live with diagnosed dementia, including Alzheimer鈥檚 disease, which accounts for approximately 70 percent of cases. The cause of this degenerative brain disease is largely unknown and no effective treatment exists. The disease has a devastating effect on individuals and their families.
Our genome contains all the information necessary to form a complete human being. This information, encoded in our DNA, stretches over one to two metres long but still manages to squeeze into a cell about 100听times smaller than a green pea. To do so, the genome has to be compacted.
The hottest point on a gaseous planet near a distant star isn鈥檛 where astrophysicists expected it to be 鈥 a discovery that challenges scientists鈥 understanding of the many planets of this type found in solar systems outside our own.
Unlike our familiar planet Jupiter, so-called hot Jupiters circle astonishingly close to their host star -- so close that it typically takes fewer than three days to complete an orbit.听 And one hemisphere of these planets always faces its host star, while the other faces permanently out into the dark.
Researchers demonstrate for the first time the potential of existing technology to directly detect and characterize life on Mars and other planets. The study, published in听, used miniaturized scientific instruments and听 new听microbiology听techniques to identify and examine microorganisms in the Canadian high Arctic 鈥 one of the closest analogs to Mars on Earth.
The afterglow from the distant neutron-star merger has continued to brighten 鈥 much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light years away and sent gravitational听waves rippling through the universe.
An over-reliance on self-report screening questionnaires, wherein patients essentially define their own condition, in place of diagnostic interviews conducted by a health care professional, has resulted in over-estimation of the prevalence of people with depression in many research studies 鈥 often by a factor of two to three times. This is according to a study published in the Canadian Medical Association Journal. The study found that over 75% of recent research on depression prevalence has been based exclusively on patient completed questionnaires.
Frequently encountered in the elderly, Alzheimer鈥檚 is considered a neurodegenerative disease, which means that it is accompanied by a significant, progressive loss of neurons and their nerve endings, or synapses. A joint French and Canadian study published in Scientific Reports now challenges this view.
Children with Autism Spectrum Disorders (ASD) often have a hard time switching gears from one task to another. But being bilingual may actually make it a bit easier for them to do so, according to a new study which was recently published in Child Development.
A study by a group of researchers including those from The Montreal Neurological Institute and Hospital of 缅北强奸 has tested the theory that brain degeneration in Parkinson鈥檚 disease (PD) originates in subcortical regions and spreads along neural networks to the cerebral cortex. By analyzing data on PD patients and healthy controls collected over one year, the researchers found that brain regions closely connected to subcortical regions showed the most degeneration over the one-year period in PD patients, and that this happens earlier than previously thought.
New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the source鈥檚 environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power.
The findings by an international team of astronomers, including Victoria Kaspi and Shriharsh Tendulkar of 缅北强奸, appear in the January 11 edition of Nature and are highlighted on the cover of the journal.
缅北强奸 researchers contribute to three of 10 鈥榙iscoveries of year鈥 selected by Quebec Science for 2017
Qu茅bec Science magazine has selected its for 2017, including three involving 缅北强奸 researchers. The annual list has highlighted top scientific research from across Quebec for the past 25 years, and 缅北强奸 has been cited more than any other institution during that quarter-century.
Here are the selected discoveries involving 缅北强奸 scientists for the past year:
A regimen of a novel bone anabolic medication (which builds bone mass) followed by an antiresorptive agent (which maintains bone mass) has been shown to significantly reduce the risk of fracture among post-menopausal women with severe osteoporosis, according to results of a clinical trial published in The New England Journal of Medicine.
