A team of researchers has resolved its very special structure for the first time. Sleeping sickness-causing parasites contain an unusual protein synthesis machinery. Ribosomes are among the most important molecular machines within the cell that hardly changed in the course of evolution. Their function is to read copies of our genes, or building plans, and to translate them into proteins. The study was published in Science.

Two Nobel laureates launched what has been dubbed “Australia’s most advanced electron microscope” at the University of Sydney’s Nanoscience Hub this week. The 4.5 m tall Thermo Fisher Themis-Z transmission electron microscope is so powerful it can capture objects that are mere picometres in size or one trillionth of a meter.
It can see down to levels of about 0.06 nanometers, which is about half the size of a hydrogen atom,” said New South Wales Chief Scientist and Engineer Professor Hugh Durrant-Whyte at the launch event.
A study compared on older cancer patients undergoing major cancer surgery, propofol-based general anesthesia may reduce the incidence of delayed neurocognitive recovery versus sevoflurane-based general anesthesia. The study was published in the September issue of the British Journal of Anesthesia.
According to a study, researchers examine people living in the most deprived neighborhoods are 24% more likely to die alone at home than those in the least deprived areas. Dr. Anna Schneider and Dr. Iain Atherton analyzed data on all 53,517 people who died within a year after the Scottish census 2011, using the census and death record data.

Physician assistants (PAs) exhibit equal performance on the clinical skills of medical residents (MR) with six to 24 months of experience in the intensive care unit (ICU). The study was published in the Journal of Evaluation in Clinical Practice.
Preparations for Ayushman Bharat began two years before Union finance minister Arun Jaitley announced the government’s flagship health insurance programme in his 2018 Budget speech. The training of a new cadre of community health officers to staff health sub-centres that serve a population of 5,000 began across many states in summer 2017, setting the stage for the treatment of simple fever, infections and pain, and early diagnosis and timely referrals to hospitals at the village level.
In these steamy days of late summer, when large men in pads batter one another on the playing field, some try to speed their recovery on the sidelines by breathing pure oxygen.
A study showed that heavy astronauts risk eye damage caused by space-flight. They all will be paying close attention to new research into a condition called spaceflight-associated neuro-ocular syndrome (SANS), which causes potentially damaging changes in the eye during spaceflight. The study was published in the American Journal of Physiology suggests the potential severity of the syndrome may be related to how much an astronaut weighs.
The U.S. Food and Drug Administration announced that it has awarded five grants totaling up to $6 million per year over the next five years to Pediatric Device Consortia (PDC) across the country that will provide advice and support services to innovators of children's medical devices. The program aims to enhance the development, production and distribution of pediatric medical devices and has awarded $37 million to various consortia since 2009.
Researchers have identified four types of neurons in the peripheral auditory system, three of which are new to science. The analysis of these cells can lead to new therapies for various kinds of hearing disorders, such as tinnitus and age-related hearing loss. The study is published in Nature Communications.
