Laanes' five-year project 'Translating Memories: The Eastern European Past in the Global Arena' investigates how literature, cinema, and art shape global perceptions of WWII and Soviet regimes. The team will analyze aesthetic and political debates around these works to break local history deadlocks.
Researchers in Estonia have discovered a significant connection between deep-sea methane emissions and the onset of ice ages. The study reveals that methane release episodes in the Arctic Sea occurred three times over the past 160,000 years, with each episode lasting around 10,000 to 20,000 years.
A novel open-source computational framework promotes affordable and routine NIPT applications in clinics, detecting fetal trisomies and parental chromosome origin from maternal blood samples. The framework incorporates machine learning methods to estimate euploidy or trisomy for each studied chromosome.
A recent Nordic collaboration study found no significant difference in functional outcomes between operative and non-operative treatment in patients over 60 with displaced proximal humerus fractures. Non-operative treatment using a collar and cuff sling and physiotherapy was as effective as surgery in improving patient recovery.
A new hybrid technology called Optiverter combines photovoltaic power optimizers and grid converters to maximize energy harvest from PV modules. The Optiverter ensures maximum energy production even in heavy or opaque shade, making it a significant improvement over current technology.
The Estonian e-residency program mainly benefits citizens from digitally advanced countries, while those from less developed countries apply for practical reasons. The study highlights the need for further analysis on the potential digital divides and inequalities related to e-residency
Researchers analyzed 80 endometrium samples to improve diagnosis accuracy. They found that the day of menstrual cycle reported by women often does not match the actual phase. The study aims to establish causes and treatments for endometriosis, a disease affecting 10-15% of reproductive-aged women.
Scientists found contrasting latitudinal gradients in woody and herbaceous communities, with closely-related species in tropical rain forests and temperate grasslands. The study supports the view that different regions act as evolutionary cradles or museums, influencing diversity patterns.
Scientists at Estonian Research Council developed a new method for improving air purifier efficiency by analyzing oxygen adsorption. The research, published in Surfaces and Interfaces, found that oxygen plays a significant role in photocatalytic processes alongside UV radiation.
Researchers developed precision-guided anticancer nanoparticles that effectively target peritoneal cancer cells, reducing side effects. The use of guiding molecules improves drug solubility, selectivity, and release in tumor cells.
A novel plasma water treatment method by electrical discharge has been developed, producing drinking water as suitable for consumption as ozonation, without carcinogens or high costs.
Researchers studied how fish adapt to rapid changes in freshwater environments and found they can react quickly when alone or in groups. The study's findings suggest that fish use cues from obstacles to find energetically-beneficial places in the flow.
Research found that combining insecticide thiacloprid with fungicide tebuconazole increases toxic effects on parasitoid wasps, potentially harming ecosystems. This synergy is a concern for agroecosystems and should influence pesticide risk assessment.
Researchers at Tallinn University of Technology developed a method to remove antibiotic residues from wastewater using metal-doped organic aerogels. The most effective material was found to be nickel-doped aerogel, which showed excellent adsorbent properties and photocatalytic degradation capabilities.
Scientists are creating new receptor-molecules and nanostructures to detect and destroy industrial pollutants like pesticides, herbicides, and pharmaceuticals. The goal is to develop a more effective technology for cleaning the environment, addressing a major issue due to the 'chiral' nature of these pollutants.
Estonian scientists have developed a genetic testing technology called TAC-seq, which enables precise analysis of clinical biomarkers at the single-molecule level. This method raises the precision of biomarker analysis and is poised to make it more affordable.
A collaborative study analyzed over 5700 individual samples from 300 localities across Estonia, discovering 52 species of Myriapoda. Notably, six species were found to be at their range limits, while one was introduced by humans.
Materials engineers are developing environmentally friendly materials, including graphene-based nanofibers, for various applications such as environmental protection, agriculture, medicine, and clothing industry. These nanofibers offer unique properties like conductivity, strength, flexibility, and bio-basis, making them promising for ...
Researchers have sequenced the Eurasian perch genome, which is three times smaller than the human genome yet contains over 23,000 genes. The study reveals the genetic mechanisms behind the species' ability to adapt to extreme environmental conditions and its significant impact on methane cycle in lakes.
A study published in Human Reproduction found that accounting for cellular variability in endometrial gene expression profiles improves the accuracy of biomarker discovery. This approach can increase IVF success rates for couples who have experienced repeated IVF failure.
Scientists have identified 20 new gnat species in the Brazilian Atlantic Forest, shedding light on the region's rich biodiversity. The discovery highlights the importance of this ecosystem in hosting endemic species.
Researchers found that inoculation of rice plants with Brevibacterium linens RS16 improved photosynthetic traits and reduced volatile emissions in response to salt stress. This non-invasive approach enhances plant salinity tolerance, offering a potential solution for crop productivity under saline conditions.
A study by Ulrike Rohn and Mats Nylund reveals that TV audiences create value through sharing activities, including distribution, interaction, and audience circulation. Successful TV providers must provide a platform for audience input, stimulate engagement, and promote viral sharing.
Researchers at Tallinn University developed three serious games to teach engineering students about agile methodologies, programming, and the 5S methodology. The games aim to develop teamwork, problem-solving skills, and perseverance in players, with a focus on real-time feedback and control mechanisms.
Research suggests that minimum insolation hours requirements for nearly zero energy buildings are unjustified, as they increase the risk of overheating. Dynamic solar shading proved to be more efficient than static shadings in reducing heat losses.
Researchers found that drained nitrogen-rich peatlands produce laughing gas, a major greenhouse gas. The study revealed that soil moisture, temperature, and cultivation play key roles in laughing gas emission from organic soils.
