A new study has shown that many of the complaints about the effects of coronavirus vaccines on periods were valid. Twenty-nine thousand people around the world were studied on a wide range of factors and compared with those who hadn’t been vaccinated. The results showed that people who received the vaccination experienced an average delay in getting their periods by 1 day compared with those who hadn’t been vaccinated. The study published in the British Medical Journal Tuesday reports on data from a popular period-tracking app called Natural Cycles, which includes women from around the world. Most of the participants were from North America, Britain, and Europe; researchers analyzed 14,936 cycles among those who received the vaccine and 4686 cycles among those who did not. Because users tracked their menstrual cycles every month on the app—which included information about contraceptive use and other factors—researchers were able to analyze three menstrual cycles before vaccination and at least one cycle after. They compared these results with four cycles in unvaccinated participants.

Download the list of 2% scientists of the world: This week, Stanford University, one of the top research and educational institutions in the world, released its yearly list of the “World’s Top 2% Scientists,” which includes the researchers who receive the most citations across all academic fields. The list of the top 2% most cited scientists in the world, just published by Stanford University, includes 2,273 scientists from India. However, China, which has 7,795 scientists on the list, much outnumbers this figure, which is based on lifetime citations. In the list of scientists referenced in 2021, the difference is much greater: India has 3,796, which is less than a sixth of China’s 19,459.

Due to air pollution and traffic congestion brought on by the fast development in urban travel demand, there is an increasing need for alternate means of transportation in metropolitan areas. By reducing the negative effects of network congestion, a transit system may significantly contribute to improving the sustainability of transportation in these places. A substantial fraction of customers may be persuaded to leave their own vehicles at home and take public transportation instead if the service quality was comparable to that of the automotive mode. By reducing the number of circulating cars and raising the average speed of traffic flow, a competitive transit system can increase user mobility and lower emissions from circulating vehicles. However, the amount of network travel demand that a transportation system captures primarily relies on the level of user service it provides. As a result, it's critical to balance operating costs with service quality by reducing the social, economic, and environmental costs associated with putting in place an effective and sustainable transportation system design.

The gene targeting methods like CRISPR/Cas9, is one of the most powerful technologies for correcting inconsistent genetic signatures and is widely used against various types of diseases these days. CRISPR/Cas9 based strategies have the potential to treat complex diseases as it is relatively straightforward, inexpensive, and precise system. This review article summarizes the applications of CRISPR/Cas9 genetic engineering in neurodegenerative disease models, providing therapeutic gene editing perspectives for neurological diseases. Here, understanding of CRISPR/Cas9 mediated genome editing in neurological diseases such as Alzheimer, Parkinson and Huntington’s disease have been focused by targeting specific genes involved and its potential as the most promising and emerging technologies taking into account with the low off-target effects of CRISPR/Cas9 and its highest editing efficiency.

In this work, a small office building located in Roorkee (29° 52ʹ 29.48ʺ N, latitude & 77° 53ʹ 23.73ʺ E, longitude), India, has been simulated to calculate the heating load in the winter season. The office building has a net floor area of 13.14 m2, an air-conditioned volume of 39.4,2 m3, and a total window area of 12.79 m2, the proportion of windows to walls is forty-five percent on SW and SE facades, leading to high heating demands in the winter period. The computer simulation for the reduction of the building heating demand has been carried out in Design Builder software. Five different passive strategies have been implemented to reduce the building heating demand. These passive cooling techniques include retrofit techniques such as glazing, roof, wall thermal insulation, reflective coating, and windows frame. It has been found that the building's annual heating demand of 450 kWh in the base case (without retrofit) has been reduced by 75%-85% with the application of improved glazing, roof, wall thermal insulation, reflective coatings, and improved window frames. The net savings in this analysis refer to the energy savings. The savings are calculated over a 5-month period, from November to March. Total electric units of 352 can be saved over the course of five months. Also, CO2 emissions during the winter period can reduce by 718 kg by implementing these strategies per winter season.
