This animal, a member of the chordates, can regenerate all of its organs so that each piece knows exactly how to regain functioning of all its missing body systems within a short period of time

A study encompassing some 9,000 dogs conducted at the University of Helsinki demonstrated that fearfulness, age, breed, the company of other members of the same species and the owner's previous experience of dogs were associated with aggressive behaviour towards humans. The findings can potentially provide tools for understanding and preventing aggressive behaviour.

Easy access to and control over personal information is a challenge for people experiencing homelessness. But Researchers from Dell Medical School say blockchain technology may provide a secure, digital "wallet" to increase access to health and well-being.

New research shows that patients who have had contact with the hospital due to serious glandular disease have a greater risk of subsequently developing depression. The study from iPSYCH is the largest yet to show a correlation between glandular fever and depression.

In the early 19th century in North America, parasitic infections were quite common in urban areas due in part to population growth and urbanization. Prior research has found that poor sanitation, unsanitary privy (outhouse) conditions, and increased contact with domestic animals, contributed to the prevalence of parasitic disease in urban areas. A new study examining fecal samples from a privy on Dartmouth's campus illustrates how rural wealthy elites in New England also had intestinal parasitic infections.

Individuals living with severe Alzheimer's disease showed remarkable improvements in behaviour and cognition within days of receiving an innovative new treatment that delivered low doses of radiation, a recent Baycrest-Sunnybrook pilot study found.

University of Rochester researchers have imprinted freeform optics with a nanophotonic optical element called a metasurface to create AR/VR glasses that are not only compact and easy to wear, but deliver high quality optics without looking like "bug eyes."

Scientists from the National Centre for radio Astrophysics, NCRA-TIFR, Pune used the upgraded Giant Metrewave Radio Telescope (uGMRT) to determine that AT 2018 cow, the first of a newly discovered class of cosmic explosions, has an extremely patchy environment. Sources like AT 2018cow release an enormous amount of energy, nonetheless fade extremely rapidly. This is the first observational evidence of inhomogeneous emission from a Fast Blue Optical Transient (FBOT).

mRNA can be used to produce much more than just vaccines. Around 50 different procedures for the treatment of diseases including cancer are already being studied in clinical trials. Scientists from the pharmaceutical company AstraZeneca, with the support of neutron researchers from Forschungszentrum Jülich, have now discovered how the subcutaneous administration of mRNA can be improved. The goal is for chronically ill patients to be able to self-administer the medication on a regular basis.

The successful treatment of multidrug-resistant tuberculosis requires clarification in advance as to which antibiotics the pathogens are resistant to. Classic testing is very time-consuming and delays the start of therapy. Researchers from the Research Center Borstel and the DZIF have now prepared a catalogue of all mutations in the genome of tuberculosis bacteria and on the basis of a genome sequencing can quickly and cheaply predict which medicines are most effective for tuberculosis treatment.

Impaired bone health is among the most significant long-term consequences of hematopoietic stem cell transplantation (HSCT).To address this serious problem, the International Osteoporosis Foundation Working Group on Cancer and Bone Disease has published an Executive Summary which outlines major factors affecting bone health in HSCT patients, and provides expert guidance for the monitoring, evaluation and treatment of bone loss in these patients.

In a new report, ALLEA, the European Federation of Academies of Sciences and Humanities, examines the potential of technical and policy measures to tackle science disinformation and calls for improved European exchange and coordination in this field.

The world's leading experts on natural hazards identified 47 problems that hinder the successful prevention and elimination of the consequences of the tsunami. Based on the carried out analysis, researchers have outlined directions for further scientific research.

In a number of biological processes, iron-sulfur clusters play a vital role, where they act as cofactors to enzymes. Research published in Angewandte Chemie now shows that cubic clusters can support unusual bonding states. This study shows that the cluster copes well with a multiple bond between iron and nitrogen--a structural motif that may be involved in biological nitrogen fixation.

Freiburg researchers explain an evolutionary step in the symbiosis between plants and nitrogen-fixing bacteria

Symptoms of health anxiety are common already during childhood and adolescence - and if the children do not receive the correct help, the anxiety can become a permanent problem with serious personal and socio-economic consequences. This is shown by a new research result from Aarhus University and the University of Copenhagen.

A team of researchers led by Nanyang Technological University, Singapore (NTU Singapore) has developed a device that offers a quicker and less invasive way to seal tears and holes in blood vessels, using an electrically-activated glue patch applied via a minimally invasive balloon catheter.

Migratory waterbirds are particularly exposed to the effects of climate change at their breeding areas in the High Arctic and in Africa, according to a new study published in Bird Conservation International. The research team came to this conclusion after modelling climatic and hydrological conditions under current and future climate scenarios (in 2050) and comparing the impact on the distribution of 197 of the 255 waterbird species listed under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

Scientists are warning that drinking water supplies in parts of rural West Africa are being contaminated by lead-containing materials used in small community water systems such as boreholes with handpumps and public taps.

In material physics understanding how systems interact across the interfaces separating them is of central interest. But can physical models clarify similar concepts in living systems, such as cells? Physicists (UNIGE/ UZH) used the framework of disordered elastic systems to study the process of wound healing - the proliferation of cell fronts which eventually join to close a lesion. Their study identified the scales of the dominant interactions between cells which determine this process.
