About a year ago, to pursue my academic career I moved from Italy to Sweden, specifically to Uppsala, a lovely town near Stockholm. I am now a PhD student in the local university and in some way I feel that my undergraduate days are well behind me. But you know, Uppsala is a very special city full of students from all around the world who certainly “rule” the town. Here, even if you are no longer a student, you can easily feel like one again just walking into a specific neighborhood at a specific time of the day… Or should I say night?
This neighborhood is called Flogsta, it is located in the west part of the city and most of its inhabitants (basically everyone) are students at Uppsala University. But what’s special about this place you might ask? There, every evening at about 10 p.m. the “Flogsta Scream” can be heard. If you’re from Uppsala you will surely be familiar with this particular “ritual”, or at least have heard of it. Literally. If instead you don’t know anything about it, the Flogsta Scream is (as the name suggest) a scream, but it’s also something more than that. It is a collective act in which students scream together from windows, balconies and rooftops. According to the student population, this act is a kind of “safety valve” or “a cry of anguish” over the accumulated stress of the demands of college life.
Truth be told, it is just an occasion to socialize and make some noise together, but for Uppsala students it is something that you can count on every single day. Sometimes everyone need to scream a little in life, might as well do it the Uppsala way.

From the 4th to the 8th of September the European Society of Biomaterials (ESB) hosted its 32nd conference at Palais des Congrès, in Bordeaux, France. ESRs André Plath (ETH Zürich) and Giulio Cavaliere (U. Uppsala) presented some of their current results in poster format during the conference.
“The conference was a great opportunity for networking and building a strong basis for future collaborations. The plenary talks were not only inspiring but represented the top-notch science being developed right now. It was also great to see a good mixture of academics and industries. I commend the ESB for also organizing lunches and talks with senior researchers, industrials, and editors.” says André.
”We met plenty of people working on similar projects and it was a great context to exchange ideas and get insightful feedbacks on my work. Being my first conference I also learnt a lot of useful skills on how to present my research. A lot of the plenary talks were more focus on tissues engineering so it was a good opportunity to expand my knowledge outside my research field” says Giulio

Earlier this year, I took a course titled “Research Introduction for New Ph.D. Students” at Uppsala University. In this course, I was informed of a main task of a university that may often be overlooked. I believe that most people know that two of the primary purposes of a university are education and research. However, there is another significant part of a university’s responsibility, and that is outreach. Universities conduct outreach activities to communicate their research activities to the broader public, especially those outside the academic community. Aside from increasing the general public’s interest in science and technology, a good outreach program may also be a platform for the long-term recruitment of students and researchers.
There are many outreach programs here at Uppsala, such as the annual SciFest arranged by Uppsala University and the Swedish University of Agricultural Sciences. From its website, SciFest is a “…festival with a wide range of workshops, shows, competitions, research meetings, and lectures”. This festival has activities for anyone, from kids to adults. Always attended by exhibitors from academia, government authorities, and technology companies, anyone who comes to SciFest will be sure to get a taste of research and science from different perspectives.
As university employees, BioTrib early-stage researchers are also responsible for conducting outreach activity. An outreach program does not have to be a festival, a workshop, or even anything physical. I think the BioTrib’s blog initiative is a good outreach program. With this blog, researchers affiliated with BioTrib can share snippets of our research and even issues within the academic communities to a broader audience. This is especially important for us as BioTrib’s research may significantly impact the medical world in the long term. I hope you’ve found our posts to be interesting and informative!
Titanium and its alloys are essential engineering materials. Owing to their fantastic combination of mechanical properties, they can be found in a variety of applications, such as jet engine blades and golf club heads. They are also valuable biomaterials due to their excellent corrosion resistance and biocompatibility. In the biomedical industry, titanium alloys found use in implant devices, for example, dental implants and the stem of a hip replacement. It is no wonder that they are called wonder material. Though their strength is many, titanium and its alloys’ use are still limited due to its apparent weakness, namely, its tribological properties. This means titanium alloys are not ideal in applications where they are in moving contact with another material/component.
Titanium’s poor wear characteristics have been well documented for decades. Among the many explanations, the three highly cited reasons for titanium’s poor tribological properties are :
1. Low work-hardening capability
2. Insufficient protective capability from their tribo-oxides
In the biomedical industry, this means titanium and its alloys are not the best materials to use in joint replacement. In fact, titanium is an inferior material to cobalt-chromium alloys simply because titanium has a more damaging effect on the plastic liner of a joint component, which results in a lower life of the joint replacement as a whole .
Currently, there are many research studies that try to improve the wear characteristics of titanium. Naturally, many of those are focused on improving the surface of the material since the wear is a surface phenomenon. The advancement of metal additive manufacturing may also pave the way for more opportunities to improve the wear characteristics of titanium. Indeed, this is also my personal research focus. With the many controllable parameters in additive manufacturing, e.g., scanning strategies, laser parameters, and powder composition, I hope to manufacture a better titanium surface that will be more appropriate for tribological properties. When I achieve that, you’ll be sure to hear it in BioTrib’s blog!

In May 2022, around 2,000 business leaders and politicians have been in Davos, in Switzerland, for the World Economic Forum’s (WEF) annual meeting. The WEF is an international non-governmental and lobbying organization based in Cologny, canton of Geneva, Switzerland. With the mission to “improve the state of the world by engaging business, political, academic, and other leaders of society to shape global, regional, and industry agendas”, it was founded in 1971 by German engineer and economist Klaus Schwab. The WEF is mostly known for its annual meeting in Davos. Over the course of five days, 3,000 paying members and selected participants – including investors, business leaders, politicians, economists, celebrities, and journalists – discuss global issues.
During the WEF Annual Meeting 2022, ETH Zurich hosts several exclusive events in its RETHINKING LIVING Pavilion. RETHINKING LIVING, created in the spirit of ETH alumnus A. Einstein: ”The important thing is not to stop questioning”, brings together scientists, industry experts, and outstanding global thinkers from ETH Zurich and across the world with the aim to re-think different conceptions of living, re-evaluate life choices, and re-consider the changes needed in a post-pandemic world. Will new technologies build a more sustainable, resilient, and equitable world? On the occasion of the WEF Annual Meeting and to incite exchange, three pioneering exhibits explore the human coexistence in different dimensions: the physical, “White Tower”, the cyber-physical, ”no1s1″ house, and the completely virtual, ”Digital Einstein”.
The White Tower is a 29-meter tall, entirely 3D printed building located along the Julier mountain pass in the remote Swiss village of Mulegns. The tower offers exhibitions, performances, and music. It aims to revitalize a village in decline and to describe the rich cultural history of Mulegns and its surroundings. A large portion of the tower will be built in an on-site fabrication lab. In this way, the tower provides digital skills to the mountain regions and advances local trade. It serves as a demonstration of the groundbreaking possibilities of computational design and digital fabrication, which will fundamentally change conventional buildings in the years to come.
No1s1 (no-one’s-one) rethinks collective goods and ownership. It is the first house on the blockchain that can be used by anyone but it belongs to no one. It runs itself and rents itself out. This concept of self-ownership aims to create a digital ecosystem of people, and artificial things. The prototype is a meditation cabin that disattends the usual economic and social expectations. It is decorated with LED lights, connected to a solar panel, and has comfortable seats for meditation inside. No1s1 aims to become an alternative model for real estate and infrastructure.
The final idea is a “Nature 2.0’’’, a self-sustaining human infrastructure that manages and regulates itself like a natural ecosystem. To celebrate the 100 years of Einstein’s Nobel Prize in Physics, ETH Zurich brings its most famous alumnus to life as an animated character. The implemented platform offers an opportunity to interact with a digital Einstein.
Albert Einstein studied at ETH Zurich between 1896 and 1900, graduating with a diploma in mathematics and natural sciences, and afterward obtained his doctorate at the University of Zurich. After some time in Bern, Einstein returned to his alma mater as a professor of theoretical physics between 1912 and 1914. In the interactive platform, a digital Einstein talks about his years in Zurich. The project is part of the university’s strategy to boost dialogue with society and to bring young people closer to science. Digital Einstein will be taking up his post at various locations around ETH and, eventually, abroad.
Header Image: Schematic representation of scaffolds characterized by three different lay-down patterns. (a) 0◦/90◦. (b) 0◦/60◦/120◦. (c) 0◦/45◦/90◦/135◦. 
The main objective of 3D bioprinting is to recreate human tissues with the same mechanical, structural and biological properties as the corresponding native tissue, in order to solve the problems associated with conventional transplantation techniques (donor site morbidity, organ shortage, etc.). For this purpose, different cell types combined with different biomaterials have been bioprinted according to specific models, but obtaining a 3D scaffold with the desired properties remains a challenge.
The advantage of 3D bioprinting over conventional scaffold fabrication techniques is the ability to control the 3D architecture of scaffolds through parameters such as pore size and geometry. Pore size and shape influence the resulting mechanical properties as well as cell behavior and tissue growth over time. Domingos et al. showed that for a lay down pattern of 0◦/90◦ (filament orientation between layers) with different pore sizes, poly(ε-caprolactone) scaffolds with smaller pores exhibit significantly higher stiffness under compressive conditions, which is an important property in applications such as bone tissue engineering. For different pore shapes with the following lay down pattern: 0◦/90◦, 0◦/60◦/120◦ and 0◦/45◦/90◦/135◦ (see figure) and the same porosity, the increasing number of angles between the filaments of the different layers leads to an increase in the deformability of the construct under compressive conditions.
Regarding the influence of architecture on cell behavior, viability and proliferation of human mesenchymal stem cells (hMSCs) were studied for 21 days and showed that larger pores with a lay down pattern of 0◦/90◦ improve viability and proliferation.

On September 1st 2022, at the University of Leeds, we had the honour to attend a presentation from Dr Paul Bills, reader of the BioMetrology group at the University of Huddersfield and co-investigator in the EPSRC Future Metrology Hub. His lecture – titled “Challenges in medical device development: using metrology to unlock the answers” – tackled significant aspects of advanced metrology tools that help assess personalised medical devices. This is of great relevance due to the current paradigm shift in the fabrication of these high-added value components via incorporating additive manufacturing (AM) in their production chain.
Watch Paul Bills leacture on the Challenges in medical device development: using metrology to unlock the answers below:
Dr Bills lecture went beyond the usual citation of the well-known advantages of AM in the orthopaedic field (e.g., high degree of customisation, sustainability, short lead time). One interesting topic that was discussed regarded the current gap in the literature regarding the interplay between osseointegration and infection in additively manufactured orthopaedic porous implants. These AM trabecular-like structures need further microbiological testing because they might be potential sites for deep and late infection. Furthermore, the lack of specification for components conceived by AM which possess an intricate geometry is another challenge yet to be overcome. In-situ metrology techniques could be employed to address that issue. In short, even though many advancements have been made in understanding the behaviour of AM orthopaedic implants, there is still a lot to be discovered from a metrology point of view. Understanding these will be important in ensuring the reliability of the technology for the production of implants in the orthopaedic field.
While Europe deals with severe drought ‘thought to be one of the worst ever witnessed in the continent’, another country in Asia is dealing with the other side of the spectrum. Pakistan, a South Asian country having an area roughly equivalent to combined total of Germany and France and home to the fifth largest population in the world, has been flooded with excessive rains, the worst in the country’s history. A country whose rainfall average is barely 200 mm in a good year has seen rainfalls of more than 800 mm this year on average and above 1000 mm in some regions, resulting in uncontrollable urban and flash floods, landslides, across the country. More than 60% of the country, equivalent to the total area of the UK, is under water at the moment of writing this post, 1,000+ people have lost their lives while the survivors struggle to feed their families and cattle as most of the agrarian land has been lost.
A country that is home to Himalayas and to ~7.500 glaciers, more than anywhere in the world outside of the polar regions has been facing severe climate change over the past few years. I remember growing up in Pakistan through the 90s and 2000’s. Over the years, the climate has significantly changed for worse, I have seen air conditioning moving from luxury to a necessity. Just in the month of April/May this year when a European starts to get in summer spirits, Pakistan was already witnessing temperatures ranging above 50°C, highest in the world for those months. Pakistan only contributes 0.5% to global carbon emissions yet it is the country predicted to lose all the glaciers and henceforth water supplies first.
As researchers we must not sit idle and await the eventual doom, rather it is our duty to rise up to the occasion and raise our voice / come up with solution to deal with climate crisis. A successful public awareness and collaboration campaign similar to ozone layer depletion campaign is the need of the hour to push back on anti-climate change narrative, raise awareness in the general populace and develop global policy to contain the effects.

Polyelectrolytes are charged polymers with special hydration properties. They are present in our bodies as sulfated glycosaminoglycans (e.g., chondroitin sulfate) and play an important role in lubrication and tissue homeostasis. Tissue engineering novelties are trying to bring the best out of the synthetic world, by mimicking the special properties of these electrolytes, grafted to all kinds of materials .
Kwon and Gong  studied the effect of negatively charged biomimetic polyelectrolytes for multiple applications, including low friction. Pavoor et al.  show the effects of the friction of grafting negatively poly(acrylic acid) and positively charged poly(allylamine hydrochloride) on ultra-high molecular weight polyethylene. Qin et al.  showed that the polydopamine-assisted immobilization of chitosan (net positive charge) can improve the biocompatibility and tribological properties of Cobalt Cromium implants. They demonstrated a tenfold decrease in the coefficient of friction upon brush-grafting.

Total hip arthroplasty (THA) or total hip replacement is one of the most cost effective and reliable surgical operation. This operation consists in replacing the hip joint by prosthetic components allowing the patient suffering from hip pathology (ex: osteoarthritis) to restore painless motion and improve quality of life. For this surgical procedure, different models of implants are available (materials, shape, size and fixation methods) and surgeons decide depending on the age, pathology and medical history of the patient which implant characteristics would suit best. Joint implants are made to stay viable for the longest time possible in the body without revision surgery (second surgery related to an earlier inserted hip prosthesis). Revision surgery can occur after different complications like: repeated dislocation, infection or loosening of the implant and periprosthetic fracture .
In order to identify factor contributing to revision surgery and improve surgery procedure, national patient registries have been used in several countries. In 1979, Sweden was the first country to establish a national quality register collecting data on hip arthroplasty: the Swedish Hip Arthroplasty Register (SHAR). Nowadays a lot of countries possess regional and or national Hip Arthroplasty registers like Finland (1980), Norway (1989), Denmark (1995), Australia (1999), England, Wales, Northern Ireland and the Isle of Man (2002). The main objective is to centralize information within the country to follow the evolution of the number of total hip surgery, revision surgery as well as the prevalence in certain age group. Indeed, annual report are published to summarize data collected.
More importantly, registries are used to collect data on the patient, the surgical procedure and operation outcomes. The principal advantage is the possibility to investigate adverse outcomes of primary THA leading to revision surgery and improve surgical procedure. National registries play a major role in documenting the quality of THA to describe best practices and report outlier implants . The 2019 Swedish Hip Arthroplasty Register report mention that “Never have so many hip arthroplasties been undertaken and never have so many research papers using data from the register been published during one operational year” .

Stratasys Ltd. introduced and commercialized fused filament fabrication (FFF) in 1989, under the patent name of fused deposition modelling (FDM). In this technique, the polymer/polymer composites filament are extruded from the nozzle head and then the melted polymer is deposited layer by layer to create the final product. Polycarbonate (PC), polylactic acid (PLA), and acrylonitrile butadiene styrene (ABS) are the most commonly used thermoplastics for FDM. It is also compatible with PP, PVA, and bio-compatible PEEK. FDM is by far the most popular 3D printing method, accounting for more than 41.5 percent of the market (2010) 
The main defects found in FDM printed parts are void formation and geometrical deformation. Poor interlayer bonding caused by a difference in cooling rate has a negative impact on material quality. Interlayer bonding was improved in a recent study with CF/PEEK printing  when a high chamber environment was provided, which reduced the stress acting between the layers. Figure 1 depicts the temperature distribution of the printed parts after printing at various chamber temperatures; uniform temperature distribution was achieved at 230oC. This allows the heat from the top layer, which was recently deposited through the nozzle at high temperatures, to dissipate, gradually eliminating structural imperfections. The thickness of primary and secondary crystals increases as chamber temperature rises, positively impacting the structural and mechanical properties of the printed parts. This has the added benefit of reducing shrinkage and warpage, which are other common issues with FDM printing.
In addition to the chamber temperature, numerous other parameters must be controlled, including nozzle temperature, print speed, layer thickness, infill density, infill pattern, raster angle, and so on, all of which have an impact on the surface and bulk properties of the printed parts.

Being awarded the Fields Medal, which is the equivalent of the Nobel Prize for Mathematics, is the highest professional honor for mathematicians. This prestigious international award is given every four years to mathematicians under the age of 40. Maryam Mirzakhani, an Iranian mathematician, was the first woman to reach the pinnacle of math and the only female to win this prestigious prize until now. Her achievements are absolutely astounding, linking geometry and dynamics together .
Maryam was born on 12th May 1977 in Tehran, Iran. Interestingly, as a child, she was very keen on reading novels as well as making up stories, and she thought she would be a writer. But she soon got highly interested in mathematics . She could obtain a gold medal at the International Mathematical Olympiad in 1994, scoring 41 out of 42 [2,3]. In the following year, she earned another gold medal at this competition with a perfect score [2,3]. In 1999, Maryam obtained her B.Sc. degree in mathematics from the Sharif University of Technology in Tehran. Then, she pursued her Ph.D. program at Harvard University. Her Ph.D. thesis is considered a masterpiece and led to three papers in top journals in mathematics.
Maryam became a research fellow of the Clay Mathematics Institute and a professor at Princeton University in 2004. Five years later, she continued her career at the Department of Mathematics of Stanford University. Her research was mainly focused on the theory of modular spaces of Riemann surfaces. She also contributed enormously to the fields of hyperbolic geometry, ergodic theory, and symplectic geometry. Finally, Maryam made history in 2014 and became the first woman and the first Iranian awarded a Fields Medal.
Unfortunately, this young female mathematician was diagnosed with breast cancer in 2013 and passed away on 14th July 2017 at the age of 40. The mathematics community lost one of the brightest stars, a woman who could inspire many people, particularly all the girls, to follow their dreams to succeed. It is worthwhile to mention that the International Council for Science declared Maryam Mirzakhani’s birthday, 12 May, as International Women in Mathematics Day in respect of her memory.

Header Image: Schematic in-vivo skin cancer imaging, with a synthetic bandwidth of 98 GHz using the designed ultra-wideband millimeter-wave imaging system.
Chances of early skin cancer treatment and intervention are enabled through tissue biopsy; prescribed by doctors when they suspect abnormal cell growth. The process itself requires doctors to harvest a sample of suspect tissue from individuals for external laboratory testing, leaving the patients with pain and wounds that take a long time to heal along with a period of uncertainty around cancer diagnosis whilst the sample is analysed.
However, a group of researchers from the Stevens Institute of Technology recently developed a technology to investigate abnormal tissues in-vivo and in real time by scanning a patient’s skin using millimetre-wave imaging technology, which is the same technology used in airport security scanners.
By examining 72 patients they were able to correctly differentiate benign and malignant lesions according to the way that the skin was reflecting light back. According to the research team, this happens due to the changes in the chemical composition of the cells. By utilizing an algorithm they are able to gather information and produce a 3D image in seconds even for the tiniest mole or imperfections indicative of cancer.
The device had a sensitivity and specificity of 97-98% and is comparable to even the greatest hospital-grade diagnostic instruments. Even though there are other devices available, those are not available in every clinic because of their size and cost. The technology that the team is developing is poised to integrate all the antennas and their circuits in a single chip making the device very small and low in cost.
Stepping out of the office and the concrete jungle, we found ourselves in a place where the mountains are reflecting sunlight and the snow is melting into music. When you struggle to pull out the leg stuck in the lap-high snow, you know you’re now reconnected to nature, swallowed up by the scene. Going on a hike is much more than refreshing our lungs with chill and delicious air, illuminating our sensations with splendid sceneries, or a physical workout with a limited source of food and water. It’s also an underrated choice for group activities.
What makes group hiking a good group activity? Consider these aspects:
Team building and group dynamics
✅ Interactions and conversations during the group hiking bring about the feeling of closeness and togetherness
✅ There must be a decision-maker leading the way and choosing the route, so you have to trust your teammates! As the leader or any member of the group, it’s important to make sure not to walk too fast and look after your mates who might be left behind
✅ Accomplishing a common goal (in this case, finishing the trail) with everyone’s presence and participation builds up the inclusiveness and strengthens the team spirit
Leisure and Wellness
✅ Pack only essential things and leave behind luxury supplements as well as tasks that are undone can be mentally challenging, but the tension is instantly released the moment you are on your way
✅ While finding our balance of walking on snowy, slippery trails, we focus on very minimum things: breathing and steps, which distracts us from all the complexity of real life. This simplicity brings the mental calmness and quietness
✅ A break from the daily routine helps a lot with regenerating the efficiency and improving the performance at work. When your mental battery is drained off, go on a hike and come back with a fully charged one
The glimpse of the million-year-old landscape reminded us of the infinity of the world and the smallness and finitude of being, meanwhile inspiring us with the courage and strength of people who conquered nature before us!
A big shout out to everyone involved in organising such a fantastic trip!

In 2015, the United Nation General Assembly adopted the 17 sustainable development goals (SDGs, see figure) described as a “universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity” . These goals follow the previous set of Millennium Development Goals (MDGs) adopted in 1990 which were focused on reducing poverty, easing hunger and child mortality, and improving access to clean water and sanitation. As the consequences of climate change, like increased air pollution, sea level rise, drought, disappearance of ecosystems are affecting negatively more and more populations, the United Nation oriented the SDGs toward the limitation of climate change. Sustainable development aims at managing human activity to meet today’s population needs without compromising resources for future generations.
The Intergovernmental Panel on Climate Change (IPCC), the United Nation body responsible for assessing the science of climate change, reminds us that climate change and sustainable development are fundamentally connected. Indeed, limiting global warming can make it much easier to achieve the SDGs. Moreover, the connection is also made in a sense that, as mentioned previously, some of the SDGs are specifically dedicated to counteracting the effect of climate change, such as SDG 14 (life below water) and 15 (life on land) for protecting ecosystems, and SDG 13 (climate action) for taking urgent action to combat climate change. The result of this close link is that action in one area of the SDGs will affect outcomes in other areas, such as climate adaptation measures that benefit local ecosystems and health. The IPCC highlights the fact that adaptation measures have to be taken at all levels in order to favorize synergy between the different goals for sustainable development .
Biomedical research trying to improve patient’s everyday life can be used to support goal number 3: good health and well-being. As we are working in order to be useful to people, how can we make research activity more sustainable in practice from an environmental perspective? In 2020 an article titled “Ten simple rules to make your research more sustainable” was published in Plos Computational Biology by Anne-Laure Ligozat et al. In this article, the authors based their reflection on the SDGs and underline the fact that all human activity including research needs to be more sustainable by reducing the carbon footprint and environmental impact . The ten rules described in the article are the following:
Small actions are a good start to modify habits step by step.
