正文(英文) | ![]() ‘Gynae Geek’ Dr Anita Mitra ![]() Here’s a batch of fresh news and announcements from across Imperial. From an exploration of changes in menstrual cycles during COVID-19, to a new report charting rising levels of atmospheric methane, here is some quick-read news from across the College. COVID-19 and periods research![]() Imperial’s Honorary Research Fellow, Dr Anita Mitra – known as the ‘Gynae Geek’ on Instagram – specialises in obstetrics and gynaecology and is running an online survey investigating how common changes in the menstrual cycle have been during COVID-19 in the UK, and what lifestyle factors have impacted this. Dr Mitra said: “I really want to continue answering questions that are important to people, like ‘why are my periods so painful?’ or ‘why do I have discharge?’ A lot of patients have unanswered questions and want to know more about their health. Since lockdown began in the UK, I noticed a lot of people saying their periods had stopped or were more painful and I wanted to dig deeper.” Within two hours of posting the online survey, Dr Mitra had received over 2,000 responses and since then, over 12,000 people have responded. “We’re keeping the survey open for another two weeks and anyone who has a menstrual cycle is welcome to complete it. Face timingNeotropical bats show a wide range of diets and facial shapes to match – from long-snouted nectar feeders to flat-faced fruit eaters. Researchers had previously determined (see video above) that these diverse faces evolved as a result of heterochrony – differences in the exact timing and rates of processes during embryo development. Now, the team, led by Imperial researcher Dr Arkhat Abzhanov, have uncovered some of the cellular mechanisms explaining for the first time how heterochrony works. They found that bats with long faces maintain high level of cell proliferation in the snout tissue for much longer than bats with ‘normal’ faces, whereas same cell populations in their short-faced relatives race through this stage of development. The team are now looking for the genetic changes that resulted in such species-specific differences in cell behaviours.

However, automated searches for new methods are often extremely costly in terms of computing power, leaving them out of reach for most companies. Now, a team from Imperial have devised a new way of ‘sampling’ that slashes these costs without sacrificing accuracy. The team’s paper recently won an honourable mention for outstanding paper award at the International Conference in Machine Learning. Read more about their work on the group's blog. Atmospheric methane increasing
One of the report’s authors, Imperial’s Dr Apostolos Voulgarakis, said: “There has to be a discussion on methane mitigation that establishes it as a key player in climate change. This recent rapid increase comes from sectors like animal farming and industrial-scale gas leaks.” By 2050, unchecked global warming could reach 3-4°C, leading to increasing extreme weather and massive socio-economic disruption. The report underlines the need for policies to control methane emissions in line with the Paris Agreement, such as replacing oil and natural gas in homes and cars, as well as farming fewer animals.
