The World Health Organization has recently declared the China coronavirus a global health emergency. 1 What’s worse is that cases of the coronavirus have jumped tenfold. The death toll is 304 and rising. 2
It would be an understatement to say that there is a growing sense of panic. The best advice I’ve heard is to stay calm and take pratical measures to protect yourself.
Experiences early in life have an impact on the brain’s biological and functional development, shows a new study by a team of neuroscientists. Its findings, which centered on changes in mice and rats, reveal how learning and memory abilities may vary, depending on the nature of individual experiences in early life.
“The implications of this are many, including environmental influences on mental health, the role of education, the significance of poverty, and the impact of social settings,” says Cristina Alberini, a professor in New York University’s Center for Neural Science and the senior author of the paper, which appears in the journal Nature Communications.
“These results also offer promise for potential therapeutic interventions,” add Alberini and Benjamin Bessières, an NYU postdoctoral researcher and the paper’s co-lead author. “By identifying critical time periods for brain development, they provide an indicator of when pharmaceutical, behavioral or other type of interventions may be most beneficial.”
Fragrance helps learning even during sleep!
Effortless learning during sleep is the dream of many people. The supportive effect of smells on learning success when presented both during learning and sleep was first proven in an extensive sleep laboratory study. Researchers at the University of Freiburg—Medical Center, the Freiburg Institute for Frontier Areas of Psychology and Mental Health (IGPP) and the Faculty of Biology at the University of Freiburg have now shown that this effect can be also achieved very easily outside the lab. For the study, pupils in two school classes learned English vocabulary—with and without scent sticks during the learning period and also at night. The students remembered the vocabulary much better with a scent. The study was published in the Nature Group’s Open Access journal Scientific Reports on 27 January 2020.
“We showed that the supportive effect of fragrances works very reliably in everyday life and can be used in a targeted way,” said study leader PD Dr. Jürgen Kornmeier, head of the Perception and Cognition Research Group at the Freiburg-based IGPP and scientist at the Department of Psychiatry and Psychotherapy at the University of Freiburg—Medical Center in Germany.
The smell of roses when learning and sleeping
For the study, first author and student teacher Franziska Neumann conducted several experiments with 54 students from two 6th grade classes of a school in southern Germany. The young participants from the test group were asked to place rose-scented incense sticks on their desks at home while learning English vocabulary and on the bedside table next to the bed at night. In another experiment, they also placed the incense sticks on the table next to them during a vocabulary test at school during an English test. The results were compared with test results in which no incense sticks were used during one or more phases.
Walking and running may affect the functional connectivity of brain networks in different ways, according to a new study.
Chinese health officials have already been administering the HIV and flu drugs to fight the coronavirus. The use of the three together in a cocktail seemed to improve the treatment, the Thai doctors said.
Another doctor said that a similar approach in two other patients resulted in one displaying some allergic reaction but the other showed improvement.
“We have been following international practices, but the doctor increased the dosage of one of the drugs,” said Somsak Akkslim, director-general of the Medical Services Department, referring to the flu medicine Oseltamivir.
When doctors in a Washington hospital sought to treat the first confirmed case of the Wuhan coronavirus in the United States on Wednesday, they tapped a device called Vici that allowed them to interact with their patient not in person, but through a screen.
The telehealth device, which looks like a tablet on wheels that doctors can use to talk to patients and perform basic diagnostic functions, like taking their temperature, is one of a handful of high-tech machines that doctors, airport workers, and hotel staff are using to help contain the outbreak that has been sweeping the world since it was discovered in Wuhan, China in late December.
“Caregivers provide care within the isolation unit, but technology is allowing us to reduce the number of up-close interactions,” says Dr. Amy Compton-Phillips, chief clinical officer at Providence Regional Medical Center in Everett, Washington, where the patient is being treated. Vici, made by Santa Barbara, California-based InTouch Health, resembles a tablet on wheels, and can protect caregivers from infection.
A Chinese woman infected with the new coronavirus showed a dramatic improvement after she was treated with a cocktail of anti-virals used to treat flu and HIV, Thailand’s health ministry said Sunday.
The 71-year-old patient tested negative for the virus 48 hours after Thai doctors administered the combination, doctor Kriengsak Attipornwanich said during the ministry’s daily press briefing.
“The lab result of positive on the coronavirus turned negative in 48 hours,” Kriengsak said.

Edward Alexander Bouchet (September 15, 1852 – October 28, 1918) was an African American physicist and educator and was the first African-American to earn a Ph.D. from any American university, completing his dissertation in physics at Yale in 1876. While completing his studies, Bouchet was also the first African American to be inducted in to Phi Beta Kappa for his stellar academic performance in his undergraduate studies. Bouchet’s original research focused on geometrical optics, and he wrote a dissertation entitled “On Measuring Refractive Indices.”
Unfortunately, after completing his dissertation, Bouchet was unable to find a university teaching position after college, probably because of racial discrimination. Bouchet moved to Philadelphia in 1876 and took a position at the Philadelphia’s Institute for Colored Youth (now Cheyney University of Pennsylvania), where he taught physics and chemistry for the next 26 years. Bouchet spent the next several years in several different teaching positions around the country. In 1916, Bouchet returned home to New Haven in poor health, and died in 1918 at age 66.
Dr. Bouchet’s impact on physics still resonates today around the world. The American Physical Society (APS Physics) confers the Edward A. Bouchet Award on some of the nation’s outstanding physicists for their contribution to physics. The Edward Bouchet Abdus Salam Institute was founded in 1988 by the late Nobel Laureate, Professor Abdus Salam under the direction of the founding Chairman Charles S. Brown. In 2005, Yale and Howard University founded the Edward A. Bouchet Graduate Honor Society in his name.
Did product safety laws lead to the dumbing down of science toys?
“Users should not take ore samples out of their jars, for they tend to flake and crumble and you would run the risk of having radioactive ore spread out in your laboratory.” Such was the warning that came with the Gilbert U-238 Atomic Energy Lab, a 1950s science kit that included four small jars of actual uranium. Budding young nuclear scientists were encouraged to use the enclosed instruments to measure the samples’ radioactivity, observe radioactive decay, and even go prospecting for radioactive ores. Yes, the Gilbert company definitely intended for kids to try this at home. And so the company’s warning was couched not in terms of health risk but rather as bad scientific practice: Removing the ore from its jar would raise the background radiation, thereby invalidating your experimental results.
The Gilbert U-238 Atomic Energy Lab put a positive spin on radioactivity
The A.C. Gilbert Co., founded in 1909 as the Mysto Manufacturing Co., was already a leader in toys designed to inspire interests in science and engineering. Founder Alfred Carlton Gilbert’s first hit was the Erector Set, which he introduced in 1913. In the early 1920s, the company sold vacuum tubes and radio receivers until Westinghouse Electric cried patent infringement. Beginning in 1922, A.C. Gilbert began selling chemistry sets.
