UNSW researchers have discovered a new way to detect ultralow levels of microRNA in a blood sample which could make the diagnosis of cancer and other illnesses quicker and more efficient.

According to a new study of mice and humans, tiny tunnels run from skull bone marrow to the lining of the brain and may provide a direct route for immune cells responding to injuries caused by stroke and other brain disorders. Bone marrow, the spongy tissue inside most of our bones, produces red blood cells as well as immune cells that help fight off infections and heal injuries. The study was published in Nature Neuroscience.
Researchers examined the protein structures, about 30% of the proteins encoded by the human genome are membrane proteins that span the cell membrane so they can facilitate communication between cells and their environment. These molecules are critical for learning, seeing, and sensing odors, among many other functions. The study was published in the Proceedings of the National Academy of Sciences.
Researchers show that a widely used chemical tracer, combined with a cutting-edge microscope, can track metabolic changes within the living cells of animals. Imaging tools like X-rays and MRI have revolutionized medicine by giving doctors a close-up view of the brain and other vital organs in living, breathing people.
A new way to zoom in at the tiniest scales to track changes within individual cells. The tool combines a widely used chemical tracer, D2O, or heavy water, with a relatively new laser-imaging method called stimulated Raman scattering (SRS). The study was published in Nature Communications.
Scientists conducted a study at unraveling how nature versus nurture plays out in space. As part of NASA’s Twins Study, they collected biological samples from each of the Kellys before sending Scott to the International Space Station for a year starting in March 2016.
Meanwhile, his brother Mark, who retired as an astronaut in 2011, remained on Earth to serve as the control subject. By analyzing how each twins’ biological markers evolved during the mission, the researchers learned a great deal about how the human body reacts both physically and mentally to extended periods of spaceflight.
Researchers estimated a significant proportion of moderate-to-deep sedation is performed by sedation practitioners under the indirect supervision of an anesthesiologist but there are limited safety data available. This was a prospective national observational study. Data were collected with a modified adverse event reporting tool from the International Sedation Task Force of the World Society of Intravenous Anaesthesia.
A total of 24 hospitals in the Netherlands where moderate-to-deep sedation was performed by sedation practitioners from the 1 February 2015 to 1 March 2016. Consecutive adults undergoing moderate-to-deep sedation for gastrointestinal, pulmonary and cardiac procedures.
Researchers have identified physicians’ familiarity with palliative or hospice care personnel or through their patients as key. Another critical factor, of course, is receptivity to difficult conversations and palliative approaches by the patients and families themselves. The study was published in Palliative Medicine and Health Affairs.
A new study published in the Lancet journal EClinical Medicine suggests that more mosquito nets are likely needed between mass campaigns to keep malaria cases in check. Writing in an accompanying commentary, Johns Hopkins Center for Communication Programs' Hannah Koenker, PhD, says the paper shows that the loss of treated bed nets between mass campaigns may have a much greater impact on malaria transmission than previously understood.
The gene FKBP5 is a critical regulator of the stress response and affects how we respond to environmental stimuli. Previous studies have shown that certain variants of this gene play a role in the development of neuropsychiatric disorders such as posttraumatic stress disorder, depression, suicide risk, and aggressive behavior.
The study was published in the Journal of Neuroscience, has confirmed this association in a cohort of more than 1,500 people of both European American and African American descent who experienced motor vehicle collision trauma.
