Michigan-native doctor was honored in his hometown for making national headlines after helping a paralyzed man walk again.

In a recent study, scientists at Baycrest’s Rotman Research Institute (RRI) found that research participants moved their eyes to determine whether they had seen an image before, and that their eye movement patterns could predict mistakes in memory. They obtained these results using an innovative new eye tracking technique they developed.
“Our findings indicate that eye movements play a functional role in memory retrieval,” says Dr. Jennifer Ryan, senior scientist at the RRI and Canada Research Chair in Cognitive Neuroscience of Memory. “They can tell us a lot about someone’s memory.”
This study builds on previous Baycrest research examining the link between eye movements and memory, including the role of our eye movements in memorization and the weakening connection between our eye movements and our brain activity as we age.
A lithium-ion battery that is safe, has high power and can last for 1 million miles has been developed by a team in Penn State’s Battery and Energy Storage Technology (BEST) Center.
Electric vehicle batteries typically require a tradeoff between safety and energy density. If the battery has high energy and power density, which is required for uphill driving or merging on the freeway, then there is a chance the battery can catch fire or explode in the wrong conditions. But materials that have low energy/power density, and therefore high safety, tend to have poor performance. There is no material that satisfies both. For that reason, battery engineers opt for performance over safety.
“In this work we decided we were going to take a totally different approach,” said Chao-Yang Wang, professor of mechanical, chemical and materials science and engineering, and William E. Diefenderfer Chair in Mechanical Engineering, Penn State. “We divided our strategy into two steps. First we wanted to build a highly stable battery with highly stable materials.”

Researchers at the National Institute of Allergy and Infectious Diseases (NIAID) report new data that support the hypothesis that remdesivir, a drug with broad antiviral activity, may be a promising treatment against Middle East respiratory syndrome coronavirus (MERS-CoV).
In the team’s experiments, remdesivir reduced the severity of disease, virus replication, and damage to the lungs when administered to infected monkeys. The authors suggest that it be considered for implementation in clinical trials and that it may also have utility for other, related coronaviruses, such as SARS-CoV-2 (previously known as 2019-nCoV).
The experimental antiviral remdesivir successfully prevented disease in rhesus macaques infected with MERS-CoV. Remdesivir prevented disease when administered before infection and improved the condition of macaques when given after the animals already were infected.
Is it so outlandish to believe that countries in the future might resort to military force to prevent other countries from altering the shared genetic code of humanity? Many countries have been invaded for far less.
The genetics revolution that will transform our health care, the way we make babies, the nature of the babies we make, and ultimately our evolutionary trajectory as a species has already begun. Just like parents in many places will need to make tough choices about whether, if at all, to genetically engineer their children, states will be forced to make monumental collective decisions on these issues with potentially fateful consequences.

The synchronized footage, published online in January, was assembled by a mostly anonymous online group of sleuths called Osint HK, which has been keeping tabs on protesters and journalists’ often-violent encounters with police during the more than eight months of Hong Kong’s near-daily anti-government, pro-democracy protests. Osint HK has spent hours each day scouring social networks for videos and other media to document police misconduct across Hong Kong.
The protests are still happening, but they’ve slowed due to fears over the coronavirus, which has been spreading from China across the globe. So Osint HK more recently has begun focusing its efforts on educating the public about the virus.
“People are confused, and they don’t know where to turn,” says Trey Menefee, the founder and public face of Osint HK. “We are trying to be a trusted source of information, cutting through the fog to find out what did or didn’t happen.”
Solar panels may be worse for than environment than we thought, but researchers say there’s still time to change that with a new panel design.
