Study shows surge of emergency room visits since introduction of rideshare e-scooters — ScienceDaily

A Henry Ford Health System physician is sounding the alarm on the rising number of injuries caused from riding electric scooters, calling it a growing public health concern.

In a study of e-scooter injuries, Kathleen Yaremchuk, M.D., chair of the Department of Otolaryngology — Head and Neck Surgery, says a review of emergency visits in the last three years shows e-scooter injuries have increased significantly with many of them related to head and neck injuries. The study describes how the types of injuries which include concussions, fractures, contusions and abrasions, lacerations and internal organ injuries have changed since the introduction of e-scooter rideshare systems to the public in September 2017.

The study’s break down on the type of injuries shows that head and neck injuries made up nearly 28% of the total injuries. Results were also broken down by age groups and showed that from 2009 to 2017, patients who

New global temperature data will inform study of climate impacts on health, agriculture — ScienceDaily

A seemingly small one-to-two degree change in the global climate can dramatically alter weather-related hazards. Given that such a small change can result in such big impacts, it is important to have the most accurate information possible when studying the impact of climate change. This can be especially challenging in data sparse areas like Africa, where some of the most dangerous hazards are expected to emerge.

A new data set published in the journal Scientific Data provides high-resolution, daily temperatures from around the globe that could prove valuable in studying human health impacts from heat waves, risks to agriculture, droughts, potential crop failures, and food insecurity.

Data scientists Andrew Verdin and Kathryn Grace of the Minnesota Population Center at the University of Minnesota worked with colleagues at the Climate Hazards Center at the University of California Santa Barbara to produce and validate the data set.

A study detailing the processes that control mole size may help scientists find new ways to prevent skin cancer from growing — ScienceDaily

Moles stop growing when they reach a certain size due to normal interactions between cells, despite having cancer-associated gene mutations, says a new study published today in eLife.

The findings in mice could help scientists develop new ways to prevent skin cancer growth that take advantage of the normal mechanisms that control cell growth in the body.

Mutations that activate the protein made by the BRAF gene are believed to contribute to the development of skin cancer. However, recent studies have shown that these mutations do not often cause skin cancer, but instead result in the formation of completely harmless pigmented moles on the skin. In fact, 90% of moles have these cancer-linked mutations but never go on to form tumours. “Exploring why moles stop growing might lead us to a better understanding of what goes wrong in skin cancer,” says lead author Roland Ruiz-Vega, a postdoctoral researcher at

Animal study shows treatment blocks inflammation and protects lungs without killing the flu virus — ScienceDaily

The raging lung inflammation that can contribute to death from the flu can be stopped in its tracks by a drug derived from a naturally occurring human protein, a new animal study suggests.

In mouse studies, all untreated animals given a lethal dose of influenza died within days. All but one of the infected mice treated with the experimental therapy not only survived, but remained energetic and kept weight on — despite having high levels of the flu virus in their lungs.

The experimental treatment is a heavy dose of MG53, part of a family of proteins that plays an essential role in cell membrane repair. Already identified as a potential therapy for conditions ranging from Alzheimer’s disease to persistent skin wounds, MG53 was found in this study to prevent death from a lethal flu infection by blocking excessive inflammation — without having any effect on the virus itself.

Tech Companies Need More Skilled Workers, CTA Study Shows

ARLINGTON, Va., Oct. 13, 2020 /PRNewswire/ — Three in four technology companies (75%) face difficulty finding candidates with the right skills and abilities today, according to the annual Consumer Technology Association (CTA)® Future of Work Study. For the first time, the annual study – which surveyed 240 tech industry leaders on workforce trends – also explores how the tech sector is embracing diversity and inclusion and adapting amid the COVID-19 pandemic. 

The study finds four in five (80%) employers will need more employees with technical skills. Employers say the most in-demand technical skills at their company are data analytics (57%), software development (56%) and project management (56%). However, companies are also looking beyond technical skills to soft skills. The top soft skills employers look for are communication (85%), problem-solving (83%) and critical thinking (83%). 

To find and recruit skilled candidates, almost three-quarters of respondents (72%) say they will

Study Suggests A Supernova Exploded Near Earth About 2.5 Million Years Ago, Possibly Causing An Extinction Event

Supernovas are amazingly bright explosions of massive stars at the end of their lives. During the gravitational collapse, the outer layers of the star are pushed away, and chemical elements formed inside the dying star are released into space. This cosmic dust rains down onto the Earth continuously, eventually becoming part of sediments deposited in the sea.

Research published in the journal Physical Review Letters used the concentrations of elements formed in an exploding star and preserved in oceanic sediments to hypothesize that a supernova exploded near Earth just 2.5 million years ago.

The authors, led by Dr. Gunther Korschinek from the Technical University of Munich, focused their study on ferromanganese crusts

  • Research from Australia’s national science agency suggests that the COVID-19 virus can survive on smooth surfaces for 28 days at room temperature.
  • The study tested the virus on glass mobile phone screens, plastic and paper banknotes, and stainless steel.
  • Researchers kept these surfaces in the dark during the study. UV light has been shown to kill COVID-19.
  • Previous studies have suggested the virus lingers on these surfaces for seven days or less.

A close study of the hunger hormone ghrelin shows that it affects how frequently animals eat; without it, they may forget when they last ate — ScienceDaily

A hormone that influences when and how frequently animals eat also appears to affect memory, USC scientists have found.

The study was published in the journal Current Biology on Sept. 17.

Animals and humans have the hormone ghrelin in their stomachs. Ghrelin tells animals, as well as humans, when they are hungry and helps regulate their metabolism, but scientists have never been certain how exactly it works.

To learn more about how ghrelin influences hunger, metabolism and memory, researchers at the USC Dornsife College of Letters, Arts and Sciences collaborated with international scientists on a study on rats.

They disrupted the ability of the ghrelin hormone to communicate to the vagus nerve, a nerve that signals from the gut to the brain, and then monitored the impact on their feeding and cognitive behaviors.

The rats were not anxious, but they began eating more frequently, said the study’s lead and corresponding

Transformational coaches make players more independent, less reliant, study finds — ScienceDaily

Athletes increasingly relying on a coach over the course of a season may be a sign that they aren’t progressing in their development, according to new research from Binghamton University.

On the other hand, inspirational coaches will find that their athletes will become less reliant on them over time.

“Being increasingly needed by your athletes as time goes on is not a good sign,” says Chou-Yu Tsai, assistant professor of management in Binghamton University’s School of Management. “If your athletes no longer need your leadership and guidance as time goes on, that should be seen as a positive sign that you’ve helped them in their development.”

Tsai, who studies leadership in a number of contexts, including athletics, worked with a research team consisting of San-Fu Kao of National Tsing Hua University and Robert Schinke of Laurentian University. They set out to discover how a coach’s leadership style affected athlete evaluations

Early Mammals Acted More Like Reptiles, Says Study

KEY POINTS

  • Scientists said early mammals led a less active but much longer lives
  • They analyzed teeth fossils of earliest mammals, the Morganucodon and Kuehneotherium
  • The study suggested that mammals developed some characteristics like warm-bloodedness at a later period

The first mammals that roamed the Earth millions of years ago functioned and acted more like reptiles even with their already advanced body structures, a new study showed. 

The research, published in Nature Communications, suggested there might be an overlap between warm-bloodedness and cold-bloodedness as mammals evolved in the past. It may be noted that mammals are considered as warm-blooded animals while reptiles are cold-blooded. 

As part of the study, a team of paleontologists analyzed teeth fossils from two of the earliest mammals, the Morganucodon and Kuehneotherium, which lived alongside early dinosaurs nearly 200 million years ago. This was the first time researchers used powerful X-rays to examine ancient fossils.
