A researcher at the UPV/EHU has participated in a study describing what it is during the early stages of Alzheimer's that triggers the loss of dynamics and subsequent impairment of the dendritic spines, the compartments of the neurons responsible for receiving nerve impulses from other neurons. The role played by the actin cytoskeleton of these compartments and how it responds in the presence of beta-amyloid peptides, the component most commonly associated with Alzheimer's, have been described.

In a mouse model of traumatic memory, male mice recall fear-related memories better than female mice, according to a study in Biological Psychiatry.

People with higher incomes and more education tend to have greater access to urban green spaces than their less privileged neighbors, a new University of British Columbia study of parks and greenery in 10 major North American cities has found.

Separate skeletons suggested to be from different early hominin species are, in fact, from the same species, a team of anthropologists has concluded in a comprehensive analysis of remains first discovered a decade ago.

Researchers have described a new method for the transmission of electrons between proteins that refutes the evidence from experiments until now. This process, involved in the generation of energy in both animal and plant cells, will permit better understanding of the behavior of proteins in the cells, as well as giving a deeper understanding of the energy dysfunctions that cause diseases.

A group of scientists from Russia's Ural Federal University, headed by Professor Grigory Zyryanov, synthesized a group of multi-purpose fluorophores. The scientists told about the content and results of their research on the unique technology in a respected international scientific journal "Dyes and Pigments".

Researchers at Johns Hopkins Medicine say they have added to evidence that rapid resistance gene sequencing technology can accurately speed the identification of specific antibiotic-resistant bacteria strains that sicken and kill some patients. A report on a proof of concept study, published in the January 2019 issue of Antimicrobial Agents and Chemotherapy, suggests the technology has the potential to hasten the 'personalized' choice of antibiotics critically ill patients need.

A new scientific study suggests snoek (Thyrsites atun) can recolonize the marine area of the Beagle Channel and South-Western Atlantic waters, an area in the American continent where this species competed with the hake (Merluccius sp.) to hunt preys in warmer periods. The conclusions open a new scene of potential changes that can affect trophic networks in this marine region due the effect of the rise of ocean temperatures.

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena. Now scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) report on an experiment in the Journal of Physical Chemistry Letters, where the dependence of the driven-dipole response on the bound state of an electron in a methyl iodine molecule is revealed.

Behavioural experiments confirm: Additional neurons improve brain function.

Severe burns can leave physical and psychological scars, especially in children. When a burn patient enters the clinic, doctors use factors such as the depth and size of the burn, as well as the time required for skin healing--or re-epithelialization--to determine the best course of treatment. Now, researchers reporting in ACS' Journal of Proteome Research have found another, possibly more accurate way to classify burn severity: analyzing proteins in blister fluid.

A team of scientists from the National University of Science and Technology 'MISIS', the Moscow Technological University (MIREA) and the Pirogov Russian National Research Medical University has experimentally proved the effectiveness of the formerly suggested 'light' method in oncotherapy. In a series of laboratory preclinical tests, the tumor growth stopped in 70 percent of mice, treated according to the innovative scheme. The results are presented in Pharmaceutics journal.

(Tokyo Institute of Technology) Researchers at Tokyo Tech have developed a low-cost star tracker and Earth sensor made from commercially available components. The star tracker is designed for use with micro-satellites in handling calibration observations, operation verification tests, and long-term performance monitoring during orbit. Embodying the concept of edge computing, the Earth camera performs image recognition while in orbit using a simple AI that identifies land use and vegetation distribution.

(Ulsan National Institute of Science and Technology(UNIST)) The Graduate School of Creative Design Engineering (CDE) at South Korea's Ulsan National Institute of Science and Technology (UNIST) has been invited to showcase its own style of art at the Dubai Design Week 2018, held in Dubai, United Arab Emirates.

(Ulsan National Institute of Science and Technology(UNIST)) South Korea's Ulsan National Institute of Science and Technology (UNIST) has conferred an honorary doctorate degree to Executive Dean Fawwaz Habbal from Harvard SEAS.

(Ulsan National Institute of Science and Technology(UNIST)) A recent technology transfer by Dongho Jeon in the School of Urban and Environmental Engineering at South Korea's Ulsan National Institute of Science and Technology (UNIST) is estimated to be worth KRW 100 million.

Immune cells engineered to attack childhood cancers were able to eradicate different types of pediatric tumors in mice, according to a new study from the Stanford University School of Medicine.

Researchers at the University of Exeter and the Pacific Northwest Research Institute in Seattle have developed a new risk score which takes into account detailed genetic information known to increase the chances of type 1 diabetes. This could be used to help identity babies at highest risk of developing the condition in the future. The score may also be used at the time of diabetes diagnosis to help decide if someone has type 1 or type 2 diabetes, which need very different treatments.

Only about 16 percent of US adolescents have been fully vaccinated against human papillomavirus (HPV) by the time they turn 13, despite national recommendations that call for vaccination at 11 to 12 years of age. Published in the Journal of Infectious Diseases, the new findings highlight the need for stronger efforts to encourage HPV vaccination and to improve immunization rates in this key age group.

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled what are known as topological insulators with the help of ultracold quantum gases. In the current issue of Physical Review Letters, they demonstrate how the edge states could be experimentally detected.

The organic polymer PEDOT is probably one of the world's most intensely studied materials. Despite this, researchers at Linköping University have now demonstrated that the material functions in a completely different manner than previously believed. The result has huge significance in many fields of application.

Rapid blood tests used by the NHS are unable to rule out tuberculosis (TB) and should be replaced with a new, more accurate test, a study has found.

Based on register data from 5.9 million people living in Denmark from 2000 to 2016, the study is the most detailed study of comorbidity ever conducted in the field of mental health.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer.

Researchers at Osaka University present measures for reducing a risk of uterine cervical cancer that increased by the suspension of the Japanese government recommendation for the Human Papillomavirus (HPV) vaccination and for promoting HPV vaccination after its resumption
