Why do these bagels smell so good? – A vaccinated mother gives birth to a baby with anti-SARS-CoV-2 antibodies – The influence of politics on health systems – Does walking through a door always make you forget? – Robotic surgery
Have you ever walked past a bakery and immediately felt hungry thanks to the lovely aroma of freshly baked bread? Smell plays a vital role in how we taste our food; if it smells good, chances are it tastes good too. Here, Lasekan et al. examined how the aroma of the popular bagel has changed due to differences in cold fermentation times.
- Dough A (control) was allowed to develop for one hour before baking.
- Dough B was also allowed to develop for an hour initially, but was then kneaded and placed in a cooler for 48 hours before baking.
- Pulp C was processed similarly to Pulp B, but the cooling time was reduced to 24 hours.
The main active aromatic compounds were collected by solvent assisted aroma evaporation and then characterized by a process called aroma extract dilution analysis.
The results showed that all of the bagels had similar notes of roast, malt, butter, baked potato, smoke and cookie. However, the scent notes of the long cold-fermented bagels were more intense than those produced by the control bagels. These results provide a basis for further research on the effect of cold fermentation on baked goods in the future.
It is well established that newborns can be protected against a number of potentially fatal viruses, such as tetanus or diphtheria, by vaccinating their mothers during pregnancy; the antibodies are passed from mother to fetus through the placenta.
With vaccine deployments underway in many countries, it would be hoped that similar protection against coronavirus disease 2019 (COVID-19) would occur for babies born to mothers vaccinated against the virus responsible for the disease (syndrome severe acute respiratory coronavirus 2, or SARS-CoV-2)
This indeed turned out to be the case, as shown in an exciting new case study presented by pediatricians at Florida Atlantic University. The baby, a healthy baby girl, is the first known child to be born to a mother vaccinated with anti-SARS-CoV-2 IgG antibodies detected in her cord blood.
At a time when our healthcare systems are under intense pressure, it is important to review the services offered and to implement changes when needed. Clarke and her colleagues at the University of Birmingham recently conducted a systematic review to find out how the use of ‘political skills’ can contribute to changes in health services both within and between organizations.
The review included the analysis of 62 articles published over the past 40 years and from various fields of research. The results indicate that political skills certainly have an impact, with changes implemented through five ‘thematic dimensions’ that include performance, awareness, influence, stakeholder engagement and influence on policy processes. .
Raise your hand to everyone who has walked into a room and then forgot why you were there. Interestingly, this is a well-documented phenomenon called the door effect, which literally refers to how memory can be affected by going through a gate or other boundary. Research on this effect has shown that people can forget things of recent importance when crossing a physical boundary (such as walking from room to room), imagining that they have done so (i.e. (i.e. a metaphysical limit) or even when they move from one desktop window to another on a computer.
In a study recently published in BMC Psychology, a team of researchers from the Queensland Brain Institute (University of Queensland) attempted to reproduce the gate effect using both virtual and physical environments. The team conducted four experiments that measured participants’ hot and false alarm rates to memory probes for items placed in the same room or in the previous room. Two experiments used highly immersive virtual reality, one used passive video and Experiment 4 involved moving physically from room to room.
The results of these experiments showed that there was, in fact, no significant effect of gates on a person’s memory. These results cast doubts on the true frequency of the gate effect and also on the results of previous studies on the phenomenon.
In order to recognize the growth and significant advancements in robotic surgery over the past decades, BMC surgery welcomes original submissions on robotic surgery. The collection will be edited by an international team of guest editors. The collection is open for submissions until April 1, 2022.
