A new study led by DTU Space has shown that the melting of small glaciers in northern Greenland has increased by 55 percent over the past two decades. These small glaciers make up only 4 per cent of Greenland’s ice-covered areas, but are responsible for as much as 11 per cent of the total ice loss in the country.
“We can see that there is a marked increase in the melting of the glaciers in northern Greenland. This shows that there is great instability in the ice masses that cover Greenland, and that there is a significant contribution to global sea level rises from here, ”says Shfaqat Abbas Khan, the study’s lead author.
Smaller glaciers are melting faster than the ice sheet
The glaciers examined in the study are not directly connected to the famous Greenlandic ice sheet, which gets the majority of the researchers’ attention. But according to Khan, it is important to study them because they respond differently to warming temperatures.
“The large loss of ice from these smaller glaciers is due to the fact that they are more sensitive to ongoing temperature changes and therefore melt faster than we see many other places in the Arctic,” Khan said.
Social media can be good and bad for mothers
Many mothers turn to social media to seek advice on parenting and their child’s development, claims a new study from the University of Copenhagen. According to the results of the study, this use of social media can both create a sense of community and negatively affect mothers’ confidence in their parenting ability. Ida Egmose Pedersen, the leading researcher behind the study, has expressed hope that the results “can increase professionals’ knowledge of how to talk to mothers about their digital use and well-being”.
Opens a window to the past: explores the life of 19th-century Danes
Researchers from the University of Copenhagen, the National Archives and the Copenhagen City Archives have collected Denmark’s largest historical population record to date. The data – which is now available to the public – has been collected from censuses, church records and funeral records dating back to 1787. In addition to helping Danish history buffs explore their family heritage, the researchers behind the project hope the data will provide insight into how health, prosperity and causes of death developed through the 19th century, including for specific population subgroups and occupations.
The plant cheese of the future
Researchers at the University of Copenhagen have developed a tasteless cheese-like gel of pea proteins. They now hope to identify the perfect fermentation process to give it the true cheese flavor that they say cannot be matched by other non-dairy products, such as those developed from coconut oil or nuts. “If we want to create a transition to a more sustainable cheese production using plants, we need to give the consumer something that tastes at least as good as cheese made from dairy products,” says Carmen Masiá, one of the researchers.
New sustainability center inaugurated at DTU
A new research center has been established at DTU with the aim of achieving ‘absolute sustainability’ within technology, product development and human behavior. The center, called the DTU Center for Absolute Sustainability, will specifically focus on the development of new methods and measurement techniques for evaluating different paths to sustainability. In addition to housing experts at DTU, “becoming a very important task for the center will reach the surrounding community through collaboration with companies,” says the center’s manager, Michael Zwicky Hauschild.
Denmark and Canada’s 3,962 km long border settled with the help of DTU team
Experts at DTU have helped settle the historic border conflict between Canada and Denmark, and have provided their technological know-how to determine the exact coordinates of the border, just as they have helped with the application and interpretation of the UN Convention on the Law of the Sea. . “It is an achievement we can be proud of,” said Niels Andersen, who was DTU’s representative at the signing ceremony between the countries on Tuesday.
Danish researchers will be the first to use quantum computers for grid control
DTU researchers have become the first in the world to use a quantum computer to analyze an electricity grid. Encouraged by the effectiveness of their new approach – the team solved the so-called load flow problem – they have turned their attention to examining how quantum computers can provide real-time knowledge of an electricity grid based solely on renewable energy. “They can do something that ordinary computers cannot,” said Brynjar Sævarsson, project manager. “This means that we can develop the necessary tools to safely and stably operate an electrical system based on renewable energy.”
DTU students take their competencies abroad
Two engineering students at DTU, Nicole Priddey and Anders Sonesson, have returned from Sierra Leone, where they provided technical support to Masanga Hospital. With other volunteers lacking technical skills, the two students quickly became addicted to tasks such as installing repair and maintenance systems and upgrading the hospital’s electrical installation.
The EU is investing NOK 45 million in an electric truck project
A new project funded by Horizon Europe seeks to develop high-performance power converters for heavy electric transport, and researchers from Aarhus University are leading the effort. Corneliu Barbu, associate professor at Aarhus University, is responsible for developing the “brain” for the new trucks, so that energy can be transferred quickly and efficiently from the battery to the engine. “Our goal is to develop technologies that are both robust and cost-effective, and we expect to have a prototype ready in three to four years,” Barbu said.
Comprehensive new data set describing Danish disease mortality
A group of researchers at Aarhus University has just published the most comprehensive study to date on the mortality of more than 1,800 diseases. It is called ‘The Danish atlas of disease mortality’ and is based on anonymised register data of 7.4 million Danes in the period 2000-18. The newly compiled data will be used to help physicians make more accurate forecasts as well as help health authorities and politicians formulate policies.
Polar bears in Southeast Greenland adapt to melting ice
A new population of polar bears has been discovered in southeastern Greenland, which survives despite the absence of sea ice. When they live and hunt in a way that is markedly different from other polar bear populations, “they survive in a special way,” said Kristin Laidre, a senior researcher at the University of Washington and the Greenland Institute of Nature. Videnskab.dk. Laidre and a team of Danish researchers have published a study describing the discovery, but they and other experts warn that rising temperatures will continue to threaten this and other polar bear populations.
