Donald Trump’s “America first but not alone” speech at last month’s World Economic Forum meeting in Davos may have hogged the headlines, but the meeting of world leaders was also chosen to launch the largest ever global survey of primary schoolchildren’s career aspirations.

Beating cancer with smarter use of radiation?
This is a guest post by Nature Middle East writer Hebah Salama.
Cancers infect different tissues, and so they manifest differently, in various types, and require different treatments or sometimes a combination of treatments. Throw in variability among patients as a factor, and it’s even more complicated. It’s the reason why numerous studies are carried out every year to try and gauge the most effective therapy for different cancer types.
Now, researchers from Sudan and Lebanon specializing in medical physics and biochemistry have collaborated together on one such study. Their research deals with cancer cases in children, specifically analyzing the effect of different single radiation doses of X-rays on Rhabdomyosarcoma (RMS) – a malignant tumor involving skeletal muscle tissue.
Radiation, one of the most commonly used methods of cancer treatment, is known to cause damage in both healthy and cancerous tissue. It’s what sparked the known risk-benefit-ratio debate on whether the benefits from radiation therapy outweigh the harms. Scientists often discuss the different methods in which radiation can be used while keeping its side-effects to a minimum. As well, new technologies that provide high accuracy in dose delivery have been invented for this purpose; sparing healthy cells.
In this study, the scientists treated cultured RMS cells in vitro (outside of the human body) with therapeutic X-rays. The cells have shown to be resistant to radiation. Additionally, and depending on the radiation dosages, many of the treated cells have repaired from the X-rays’ radiation damage.
The scientists use this study to demonstrate that efforts put into studying tumors’ and healthy tissues’ biological responses to radiation based on tumor type should be stepped up. The more accurate the data provided about these types of responses, the better the outcome of patient treatment is.
“The advancement in technology should be met with more scientific research,” says Alexander Fadul lead researcher.
He adds that more patient oriented studies are certainly needed to determine the different parameters of radiation.
Babies or career: How to keep young researchers in science
Could shared post-docs improve work-life balance and make academia more attractive for early career scientists?
Naturejobs journalism competition winner Ulrike Träger.
If you look for advice on work-life balance in science online, the message seems clear: it’s possible to fit a 10-hour work day around quality time with your kids and family as long as you’re organized. Flexible hours of working in the lab help. Experiments don’t mind when you do them, and can be postponed until your kids are asleep. But still, long hours are expected in order to be successful, and finding childcare during midnight experiments is not always easy if you don’t live close by. So for many (including myself, a post-doc in my late twenties pondering the right time to start a family) the prospect of having to plan each and every minute of the day to be a good parent and scientist is daunting. This leaves promising young scientists everywhere feeling like they have to choose between family and career.
A postgraduate degree and two children: it’s possible

Five tips on completing a post graduate degree from a mother who took on a PhD after staying at home for 6 years.
Contributor Anne Priestly
To be honest, I wasn’t 100% sure getting a PhD was the right choice for me. I still wasn’t quite sure what I wanted to do for a career. But then the opportunity came along that gave me the chance to pursue a postgraduate degree in biology and I couldn’t pass it up.
I was 30 years old and I already held a master’s degree in environmental science. I also had two wonderful kids and was fully involved in raising them.
My youngest child had started primary school a few weeks before and there I was at an induction session for new postgraduates. That’s right, starting a PhD when I was already busy (and sometimes overwhelmed) raising a family. I had been an at-home mom for almost six years and it felt strange to be standing there with a bunch of students fresh out of university. But it also felt like it was the right time for me to take some steps to reach my own career goals. Continue reading
Roman Egypt was home to “a good citizenship” youth organisation 2,000 years ago

Following a study of over 7,500 ancient documents on papyrus, originating from Oxyrhynchos in Egypt and discovered over a hundred years back in a rubbish dump, University of Oslo and the University of Newcastle presented what is perhaps the most systematic research of childhood in Roman Egypt, according to the university’s website.
Among their discoveries? Some 2,000 years ago, Oxyrhynchos, a town of around 25,000 inhabitants, had a youth organisation, called a “gymnasium,” in which any free-born child could enroll – slaves and girls not allowed.
Somewhere between 10 and 25% of local Egyptian boys, in addition to Greek and Roman residents of Egypt would have qualified, but typically members of affluent families and higher tax classes enrolled, according to an overview of the study released earlier this month by social historian Ville Vuolanto of the University of Oslo and April Pudsey of the University of Newcastle.
Enrollment in the gymnasium marked the transition to adulthood.
“It’s like putting together a jigsaw puzzle. By examining papyri, pottery fragments with writing on, toys and other objects, we are trying to form a picture of how children lived in Roman Egypt,” explains Vuolanto.
While well-off boys were part of the prestigious gymnasium, learning to be good citizens, others worked or landed what is termed “apprenticeship contracts,” mainly in the weaving industry. Either way, boys in ancient Egypt were not considered fully adult until they got married, usually in their early twenties. Most girls remained or worked at home, according to the study.
Slave children could also become apprentices, however, unlike “free-born” citizens they lived with their owners or “masters” not their parents during. Vuolanto says that children as young as two were separated from kin and sold as slaves.
“Little is known about the lives of children until they turn up in official documents, which is usually not before they are in their early teens,” says University of Oslo’s press release.
Motherhood and science
Kay and Keeva at SFN{credit}Courtesy Kay Tye{/credit}
Dr Kay Tye, from the Picower Institute for Learning and Memory at the Massachusetts Institute of Technology (MIT) in Cambridge, recently had a baby. Keeva is now 10 months old, and has been to the lab, on multiple trips around the world, and even gets a photo in Nature before her first birthday. In March 2013, Kay featured alongside other fantastic female scientists in the Nature article: From the frontline: 30 something science. At the time, Kay was 5 months pregnant, and was just beginning to dial down her work levels to prepare for her daughter. I caught up with her, just over a year later, to see whether her opinions on having a child whilst being a scientist had changed.
What response did you get from the article in Nature?
I got mixed responses from both ends of the spectrum. Some people really liked that I wasn’t afraid to admit I have other interests besides science, others were critical of the “one can have it all” attitude. Specifically, I was criticised for being “dismissive” of the amount of work parenthood entails. Some said that it would have been more appropriate to feature someone who already had children.
I have always wanted to be a mother, and have always looked up to women with successful careers and families, and never intended for my comments to come off as dismissive in any way. I always worried about if I would be able to make it work, and tried to focus on my mentors and role-models (including my mom, my PhD advisor, and other leaders in my field) who have had successful careers and happy families.

Careers hold scientists back from having children
Many scientists at top US institutions have had fewer children than they wanted as a result of their careers, according to a new study.
Nearly half of all female scientists and a quarter of male scientists said they would have liked more children — and a quarter of both women and men said they are likely to consider moving to a career outside science as a result.
Sociologists Elaine Howard Ecklund from Rice University and Anne Lincoln from Southern Methodist University surveyed 2,500 scientists at more than 30 leading universities in the United States for the study, which was published last week in PLoS ONE.
The survey showed that 36 percent of male postdocs and 22 percent of female postdocs had children, rising to 75 percent of male faculty members and 64 percent of female faculty members. Female faculty members had fewer children on average than their male colleagues — 1.2 children for women versus 1.5 for men.
Despite women being more likely to have wanted more children, men were unhappier about having fewer children than desired. Both men and women with children worked fewer hours than those without children. However, contrary to the researchers’ expectations, women with children worked the same number of hours as men with children — approximately 54 hours a week on average.
“Academic science careers are tough on family life,” says Ecklund, citing long hours and the pressures of working towards tenure as the main pressure points. She and Lincoln suggest on-site day care and improved mentoring programmes may help improve scientists’ work-life balance. “Universities would do well to re-evaluate how family-friendly their policies are,” says Ecklund.
