Like snowflakes, no two branches are alike. They can differ in size, shape and texture; some might be wet or moss-covered or bursting with offshoots. And yet birds can land on just about any of them. This ability was of great interest to the labs of Stanford University engineers Mark Cutkosky and David Lentink – now at University of Groningen in the Netherlands – which have both developed technologies inspired by animal abilities.

Shan received the prize for his impressive work and its great outreach.

Columbus was not the first European to reach the Americas. The Vikings got there centuries beforehand, although exactly when has remained unclear. Here, an international team of scientists show that Europeans were already active in the Americas in 1021 AD.

The Vikings sailed great distances in their iconic longships. To the west, they established settlements in Iceland, Greenland and eventually a base at L’Anse aux Meadows, Newfoundland, Canada. However, it has remained unclear when this first transatlantic activity took place. Here, scientists show that Europeans were present in the Americas in 1021 AD - precisely 1000 years ago this year. This date also marks the earliest known point by which the Atlantic had been crossed, and migration by humankind had finally encircled the entire planet.

The increasing amount of greenhouse gases in the atmosphere is causing our climate to warm at an alarming rate. The consequent changes are unprecedented, and difficult to predict due to the complexity of the Earth system. While we know that half of the carbon emissions released to the atmosphere by fossil fuel usage are re-captured by the ocean and land ecosystems, we still lack knowledge when it comes to the exact size, nature and stabilities of these carbon sinks and how these will be affected by climate change. How these sinks operate in detail, and if they indeed continue to work is vital information for societies, that must decide on pathways to climate neutrality.

On Friday October 1, Simone Gazagnes successfully defended his PhD thesis entitled "Vast and fast data in the era of large astrophysics and particle physics experiments". He received his doctorate degree 'cum laude'. A big congratulations on behalf of all ESRIG colleagues.

Vogels vliegen veel efficiënter dan drones. Maar hoe dan? Luchtvaartingenieur en bioloog David Lentink bestudeert vogels om nieuwe manieren van vliegen te ontdekken en ook om de biomechanica van de vogelvlucht beter te begrijpen. Hij verruilde onlangs de Amerikaanse Stanford University voor Groningen, omdat hij hier zijn liefde voor techniek én biologie kan combineren. Lentink is een mooi voorbeeld van een interdisciplinair onderzoeker en ook van vele andere biomimicryonderzoekers aan de RUG die hun inspiratie halen uit de natuur.

On 1 September 2021 Rob Middag has been appointed as honorary professor in Marine Trace Metal Biogeochemistry within the CIO Oceans research group. As a chemical oceanographer, Rob Middag's research focusses on the role of metals in marine ecosystems. "I look forward to the opportunities to strenghten contact with my research colleagues. But also the possibility of inspiring and involving the next generation of marine scientists through education."

In the Netherlands, hundreds of energy cooperatives try to accelerate the energy transition by developing plans for collectively owned wind and solar projects. Dur-ing the last 5 years so-called buurtwarmte (“neighborhood heat”) cooperatives were founded to realize collective sustainable district heating systems. We have studied 4 front runners, in Amsterdam, Den Haag, Groningen and Wageningen, together with colleagues of de Hanzehogeschool, TNO and a local energy coop-erative. We were interested in the question to what extent Dutch local energy cooperatives are able to develop and realize collective heating networks. Eventu-ally each of our four cases was able to develop a heating system plan and two of them are in the pre-engineering stage, but it turned out to be far from easy to develop such a system. We identified five main problems.

David Lentink, an aerospace engineer and biologist, studies birds in order to find new ways to fly, and also to better understand the biomechanics of bird flight. He recently moved from Stanford University to the University of Groningen, one of very few places where he can combine his love for engineering with his love for biology. Lentink is a fine example of the many UG researchers who take their inspiration from nature.

New Biomimetics research group joined the ESRIG institute. The Biomimetics group studies how organisms evolved to function successfully in their complex environments as inspiration to improve technology and engineering design. Their focus is primarily, but not exclusively, on aquatic and aerial behaviours including feeding, swimming and flight. Informed by scientific findings, they develop new biomimetic and bioinspired solutions for engineering and societal challenges. The technological focus is on energy harvesting, energy use efficiency, environmental cleanup and autonomous robotics. To accomplish these research and innovation goals and translate their findings to society, the group collaborates with leading scientists, engineers and companies locally, nationally and globally. To engage students as well as the general public, the group offers exciting research experiences, organizes national outreach projects and helps the international media disseminate our discoveries and innovations.

Van der Waal, die in maart is gepromoveerd op een onderzoek naar de rol van lokale energiecollectieven, stelt dat een klankbordgroep niet per se betekent dat het proces eerlijker is. Je zet bewoners in zo’n groep met vertegenwoordigers van een projectontwikkelaar en anderen die, bijvoorbeeld vanuit een gemeente, daar fulltime aan werken. Een bewoner moet proberen dat allemaal bij te houden in de avonduren. Dan is de kans aanwezig dat die onder de tafel wordt gepraat. Echte participatie is meer dan een groep bij elkaar brengen en een beetje aanhoren wat mensen te zeggen hebben en wat hun voorkeuren zijn. En daar vervolgens mee doen wat minimaal aanvaardbaar is.

The ESRIG Institute is exciting to welcome a new member to our group. As of March 1, Prof.dr.ir. D. (David) Lentink joined our institute within the Ocean Ecosystems research group.

Down in the deep dark waters of the North Sea lies Doggerland, which disappeared thousands of years ago due to the rising sea levels. Groningen archaeologists are trying to find out how the area’s inhabitants dealt with the rising water.

The grant of EUR 750,000 is for his project ‘The role of heterogeneity in controlling the geomechanical behaviour of sandstone reservoirs’.

Primary production in the Southern Ocean (SO) is limited by iron availability. Hydrothermal vents have been identified as a potentially important source of iron to SO surface waters. Here we identify a recurring phytoplankton bloom in the high-nutrient, low-chlorophyll waters of the Antarctic Circumpolar Current in the Pacific sector of the SO, that we argue is fed by iron of hydrothermal origin. In January 2014 the bloom covered an area of ~266,000 km2 with depth-integrated chlorophyll a > 300 mg m−2, primary production rates >1 g C m−2 d−1, and a mean CO2 flux of −0.38 g C m−2 d−1. The elevated iron supporting this bloom is likely of hydrothermal origin based on the recurrent position of the bloom relative to two active hydrothermal vent fields along the Australian Antarctic Ridge and the association of the elevated iron with a distinct water mass characteristic of a nonbuoyant hydrothermal vent plume.

Echo chambers in science describe the amplification and repetition of information within closed networks. Frequently used data sources can cause echo chambers as scientists keep reading similar outputs from different sources, creating false perceptions of certainty and variety of data sources. We show this effect by studying the scientific and grey literature on water use by electricity systems. The power sector is the largest contributor to anthropogenic carbon emissions and the second largest water consumer. We have assessed the scope and references of 2,426 papers and created a citation network to trace original data sources. Most data sources used for the last 30 years originate from a few old US publications, recently also Chinese, that echo through publications. This echo effect, also reflected in recent scientific publications, creates a confirmation bias, also facilitating double counting of the water intensities of electricity generation. This example from sustainability science warns of the risk of echo chambers in other scientific disciplines.

As far back as the sixth century, relics attributed to the apostles Philip and James have been held in the Santi Apostoli church in Rome. However, research suggests that the thighbone, originally thought to be that of James the Apostle, does not belong to this saint but actually to someone who lived 160 to 240 years later.

Expectations for energy storage are high but large-scale underground hydrogen storage in porous media (UHSP) remains largely untested. This article identifies and discusses the scientific challenges of hydrogen storage in porous media for safe and efficient large-scale energy storage to enable a global hydrogen economy. To facilitate hydrogen supply on the scales required for a zero-carbon future, it must be stored in porous geological formations, such as saline aquifers and depleted hydrocarbon reservoirs. Large-scale UHSP offers the much-needed capacity to balance inter-seasonal discrepancies between demand and supply, decouple energy generation from demand and decarbonise heating and transport, supporting decarbonisation of the entire energy system. Despite the vast opportunity provided by UHSP, the maturity is considered low and as such UHSP is associated with several uncertainties and challenges. Here, the safety and economic impacts triggered by poorly understood key processes are identified, such as the formation of corrosive hydrogen sulfide gas, hydrogen loss due to the activity of microbes or permeability changes due to geochemical interactions impacting on the predictability of hydrogen flow through porous media. The wide range of scientific challenges facing UHSP are outlined to improve procedures and workflows for the hydrogen storage cycle, from site selection to storage site operation. Multidisciplinary research, including reservoir engineering, chemistry, geology and microbiology, more complex than required for CH4 or CO2 storage is required in order to implement the safe, efficient and much needed large-scale commercial deployment of UHSP.

Extreme weather events are projected to change due to climate change, the risk to societies are therefore also changing. In a new study , Dr. Karin van der Wiel (KNMI) and Prof. Richard Bintanja (KNMI, Univ. Groningen) demonstrate that the increased occurrence of monthly extreme heat events is predominantly caused by a warming mean climate. In contrast, future changes in monthly heavy rainfall events depend to a considerable degree on changes in climate variability. Examining the origin of changes in extreme events, changing mean or changing variability, provides valuable insights into the processes driving these important climatic changes.

The lockdowns that resulted from the COVID-19 pandemic have reduced greenhouse gas emissions. However, in the recovery phase, emissions could rise to levels above those projected before the pandemic. It all depends on how the stimulus money that governments inject into their economies is spent.

In het snel opwarmende noordpoolgebied smelt het zee-ijs steeds verder weg. In september benaderde het zee-ijsoppervlak het laagterecord van 2012 (figuur 1). Hoewel de langjarige trend in zee-ijs overduidelijk omlaag gaat, zijn records vooral afhankelijk van de sterkte van de variaties van jaar tot jaar.

In China, approximately 10 billion online food orders were served to over 400 million customers in 2018. Together with colleagues from China and the UK, Yuli Shan, an environmental scientist at the University of Groningen, found that reusable tableware can substantially reduce packaging waste and life cycle environmental emissions.

De natuurbranden in het Arctische gebied deze zomer waren zeer uitgebreid en intens, vooral in Siberië. Hiermee steekt 2020 samen met 2019 ver uit boven voorgaande jaren wat betreft de uitstoot aan luchtvervuiling die met deze branden samenhangt (figuur 1), dat meldt de Europese instantie Copernicus Atmospheric Monitoring Service (CAMS).

The Internet facilitates connections between a range of Dutch actors with a stake in the energy transition, including governments, environmental organizations, media outlets and corporations. These connections tease a hyperlink network affecting public access to information on energy transition issues. Despite its societal relevance, however, the characteristics of this network remain understudied. The main goals of this study are to shed some light on the topological characteristics of the Dutch energy transition hyperlink network and reveal the main topics discussed in the network. To do so, we longitudinally collected data from the interactions between key Dutch actors with a stake in the energy transition. Then, these data were analyzed by employing a mixed-method approach, social network analysis and topic modeling. The results of the social network analyses reveal the existence of a sparse network in which few private companies and associations emerge as the most authoritative actors and brokers. Furthermore, our analyses show substantial differences among the communication agendas of the organizations of the Dutch energy transition hyperlink network; while public institutions focus on global, national and local policy issues, private companies, associations and NGOs pay much more attention to employment issues.

China has a rapidly growing online food delivery and takeaway market, serving 406 million customers with 10.0 billion orders and generating 323 kilotonnes of tableware and packaging waste in 2018. Here we use a top-down approach with city-level takeaway order data to explore the packaging waste and life-cycle environmental impacts of the takeaway industry in China. The ten most wasteful cities, with just 7% of the population, in terms of per capita waste generation, were responsible for 30% of the country’s takeaway waste, 27–34% of the country’s pollutant emissions and 30% of the country’s water consumption. We defined one paper substitution and two sharing tableware scenarios to simulate the environmental mitigation potentials. The results of the scenario simulations show that sharing tableware could reduce waste generation by up to 92%, and environmental emissions and water consumption by more than two-thirds. Such a mechanism provides a potential solution to address the food packaging waste dilemma and a new strategy for promoting sustainable and zero-waste lifestyles.

Er worden in Zeeland wel vaker oude botresten gevonden, maar niet vaak zijn het er zo veel als onlangs in Terneuzen. Bij de bouw van een sluis hebben onderzoekers resten van verschillende diersoorten gevonden die ongeveer 30.000 jaar geleden leefden bij wat nu Zeeuws-Vlaanderen is.

Making energy systems more efficient and sustainable has driven the career of Prof. P.V. Aravind. As a student, it led him to come to Europe to study for an MSc at the University of Oldenburg (Germany) and a PhD at Delft University of Technology, where he subsequently started his own research group. In September 2019, he moved to the University of Groningen to work, among other projects, on reversible fuel cells that can convert fuel into electricity and vice versa. ‘My dream is to create negative emission power plants and reversible fuel cells are helpful in many ways.’

Als gevolg van de opwarming smelt het zee-ijs rond de Noordpool langzaam weg: het huidige ijsoppervlak is 's zomers zo'n 40 procent kleiner dan veertig jaar geleden. Zet die opwarming door, dan wordt een ijsvrije Noordpool onvermijdelijk. Maar wanneer? Britse onderzoekers denken dat het al over vijftien jaar zover zal zijn.

A new study “The Unintended Side Effects of Bioplastics: Carbon, Land and Water Footprints” conducted by a multinational team of environmental scientists demonstrate that replacing all petrochemical plastic packaging with bioplastics is not feasible as this would lead to burden-shifting of environmental impacts. The assessment carried out in the study shows that increased use of bioplastics will result in significant growth of land and water use.

No one knew why the mysterious fortress of Por-Bazhyn had been built or why it had never been used. But this week, UG scientists presented the solution to the mystery, thanks to a new method of carbon dating.

Het bouwjaar van een mysterieus complex op de grens van Rusland en Mongolië is zeer nauwkeurig vastgesteld met een combinatie van koolstofdatering en het tellen van jaarringen in een boomstam. Het Oeigoerse klooster van Por-Bazjyn is gebouwd in 777 na Christus, tijdens de turbulente heerschappij van Tengri Bögü Khan, zo concluderen wetenschappers van de Rijksuniversiteit Groningen. Ze publiceerden hun bevindingen afgelopen maandag in PNAS.

Dating archaeological objects precisely is difficult, even when using techniques such as radiocarbon dating. Using a recently developed method, based on the presence of sudden spikes in carbon-14 concentration, scientists at the University of Groningen, together with Russian colleagues, have pinned the date for the construction of an eighth-century complex in southern Siberia to a specific year. This allows archaeologists to finally understand the purpose for building the complex – and why it was never used. The results were published in Proceedings of the National Academy of Sciences on 8 June.

Temporary reduction in daily global CO2 emissions during the COVID-19 forced confinement. Government policies during the COVID-19 pandemic have drastically altered patterns of energy demand around the world. Many international borders were closed and populations were confined to their homes, which reduced transport and changed consumption patterns. Here we compile government policies and activity data to estimate the decrease in CO2 emissions during forced confinements. Daily global CO2 emissions decreased by –17% (–11 to –25% for ±1σ) by early April 2020 compared with the mean 2019 levels, just under half from changes in surface transport. At their peak, emissions in individual countries decreased by –26% on average. The impact on 2020 annual emissions depends on the duration of the confinement, with a low estimate of –4% (–2 to –7%) if prepandemic conditions return by mid-June, and a high estimate of –7% (–3 to –13%) if some restrictions remain worldwide until the end of 2020. Government actions and economic incentives postcrisis will likely influence the global CO2 emissions path for decades.

A cautious approach to easing lockdown restrictions that reduces the risk of later lockdowns may be better for the global supply chain in the long run, according to a new modelling study by a global team with partners from Europe, the UK, the US and China.

The paper, published today in Nature Human Behaviour , is the first peer-reviewed study to comprehensively assess potential global supply chain effects of Covid-19 lockdowns, modelling the impact of lockdowns on 140 countries, including countries not directly affected by Covid-19.

Climate change caused by carbon emissions is the leading global environmental problem today. Mitigating carbon emissions and adapting to climate change requires the integration of different types of approaches to support the transformation of society towards sustainability.

Prof. Eize Stamhuis of the University of Groningen, together with industrial partners EmpowerMi and RG-projecten, has received a grant of over EUR 1 million from the Ministry of Economic Affairs and Climate. The grant is for the modification and testing of a wind turbine according to Stamhuis's Albatrozz principle. This wind turbine, located in the Noordoostpolder, will have blades with partially oscillating ends. The research and testing on an existing commercial-scale wind turbine (850 kW) will take approximately two years. With the special oscillating blades, an efficiency increase of 5 to 25% at low wind speeds is envisaged. This unique technological concept can therefore have a major impact on making energy management more sustainable.

Cities dominate global anthropogenic carbon emissions. Here, we develop an approach to interpret carbon footprints of cities by focusing on their system boundaries, double counting recognition, spatial paths and policy sensitivities. Using four megacities in China as a case study, we quantify and map urban carbon footprints from various accounting perspectives: territorial carbon emissions, community-wide infrastructure carbon footprint, consumption-based carbon footprint, wider production carbon footprint, and full-scope carbon footprint. We find that the megacities’ infrastructure carbon footprints are dominated by electricity-related emissions, whereas their consumption-based carbon footprints are significantly impacted by imports of both electricity and other products and services. Over 55% of the full-scope carbon footprints (sums of all three scopes) of Beijing and Shanghai can be attributed to upstream emissions, while in Chongqing and Tianjin territorial emissions are more important. Key urban infrastructure contributes over 70% to the total carbon emissions in import supply chains, determining the spatial paths and the carbon intensities of imports for these megacities. The main destinations of outsourced carbon emissions across the country from the megacities are found to be similar due to market domination of bulk suppliers of infrastructure-related and other carbon-intensive products. In addition, double counting of certain footprint indicators is considered small in this case, but could be amplified with increasing number of cities being assessed.

Urban activities have profound and lasting effects on the global carbon balance. Here we develop a consistent metabolic approach that combines two complementary carbon accounts, the physical carbon balance and the fossil fuel-derived gaseous carbon footprint, to track carbon coming into, being added to urban stocks, and eventually leaving the city. We find that over 88% of the physical carbon in 16 global cities is imported from outside their urban boundaries, and this outsourcing of carbon is notably amplified by virtual emissions from upstream activities that contribute 33–68% to their total carbon inflows. While 13–33% of the carbon appropriated by cities is immediately combusted and released as CO2, between 8 and 24% is stored in durable household goods or becomes part of other urban stocks. Inventorying carbon consumed and stored for urban metabolism should be given more credit for the role it can play in stabilizing future global climate.

How is it possible that an albatross doesn’t crash and die when it lands? And how come its large wings don’t break due to air resistance? That is what you would expect, according to the laws of aerodynamics. However, Professor Eize Stamhuis has discovered that albatrosses land safely by making wiggly wing movements. What is more, he sees a possible application of this oscillation technique to make the blades of wind turbines more efficient. To protect his intellectual property (IP), he has applied for a patent. He has also attracted interest from industries working on aerodynamics. So, how does he work?

The composition of unicellular marine life is changing as a result of melting Antarctic sea ice. This influences the entire food chain and deep-sea carbon storage – and thus the climate. Patrick Rozema (University of Groningen) studied this phenomenon during two field seasons on Antarctica. On 1 December – Antarctica Day – he will defend his PhD thesis.
