Eating a krill-only diet has made one variety of Antarctic penguin especially susceptible to the impacts of climate change, according to new research involving the University of Saskatchewan (USask) which sheds new light on why some penguins are winners and others losers in their rapidly changing ecosystem.
URBANA, Ill. - Mental health is a concern in rural areas, as farmers cope with stress and uncertainty due to economic and environmental conditions. Often, there are no mental health providers in the local community. Public health programs can help, but what are the best ways to reach farm populations with those programs? That's the topic of a new study conducted by a University of Illinois researcher.
Humans have an early understanding of the laws of physical reality. Infants, for instance, hold expectations for how objects should move and interact with each other, and will show surprise when they do something unexpected, such as disappearing in a sleight-of-hand magic trick.
Now MIT researchers have designed a model that demonstrates an understanding of some basic "intuitive physics" about how objects should behave. The model could be used to help build smarter artificial intelligence and, in turn, provide information to help scientists understand infant cognition.
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a way to make Colloidal Quantum Dots produce laser light with the help of an electric field.
Colloidal Quantum Dots (CQDs) are semiconductor nanoparticles that can generate vivid and saturated colours of light efficiently, which are used to make display screens of many electronic devices.
IMET RAS in cooperation with Lomonosov Moscow State University and Belgorod State University have investigated the thermal stability of the synthetic hydroxyapatite (HA) - the analogs material of human bone tissue. The obtained results have demonstrated that Al3+ doping of the HA structure in the tiny amounts enhanced its thermal stability and biocompatibility. This lead to apply this material as a coating for implants and for high-temperature bioceramics creation.
New research in Science Advances is uncovering the vital role that Precambrian-eon microbes may have played in two of the early Earth's biggest mysteries.
Theoretical prediction of molecular bond energy is of key importance for understanding molecular properties. For instance, information of chemical reaction pathways can be inferred from a numerical analysis of the bond energies involved. A well-accepted way is to calculate the difference in values of molecular energies before and after chemical bond rupture using quantum chemistry tools. However, for complicated chemical reactions, a large number of chemical bonds need to be analyzed, requiring many repeated quantum mechanics calculations that consume heavy computing resources.
Scientists from Skoltech ADASE (Advanced Data Analytics in Science and Engineering) lab have found a way to enhance depth map resolution, which should make virtual reality and computer graphics more realistic. They presented their research results at the prestigious International Conference on Computer Vision 2019 in Korea.
Thanks to the advanced possibilities, in vitro fertilization is part of everyday medical practice. The so-called swim-up method is a sperm purification method that is being used daily in andrology labs around the world as a simple step for in vitro sperm selection. This method accumulates the most motile sperm in the upper fraction and leaves sperm with low or no motility in the lower fraction by adding them to a culture medium. The reasons for the different sperm qualities are still poorly understood.
TORONTO, November 28, 2019 -Labels that warn an image has been altered or enhanced do nothing to mitigate women's negative perceptions of their appearance, according to a study published in Body Image this week. More importantly, some disclaimers heightened and even harmed body dissatisfaction in at-risk women, the study showed.
Researchers have long known that some genes can cause cancer when overactive, but exactly what happens inside the cell nucleus when the cancer grows has so far remained enigmatic. Now, researchers at Karolinska Institutet in Sweden have found a new mechanism that renders one canonical driver of cancer overactive. The findings, published in Nature Genetics, create conditions for brand new strategies to fight cancer.
DURHAM, N.C. - Duke Cancer Institute researchers have observed how stem cell mutations quietly arise and spread throughout a widening field of the colon until they eventually predominate and become a malignancy.
Kanazawa, Japan - Researchers at Kanazawa University performed a detailed investigation of the molecular mechanisms by which organic solar cells suffer damage as they are exposed to sunlight. This research has important implications for developing next-generation solar sheets that combine high efficiency, low cost, and long device lifetimes.
The "Habsburg jaw", a facial condition of the Habsburg dynasty of Spanish and Austrian kings and their wives, can be attributed to inbreeding, according to new results published in the Annals of Human Biology.
The new study combined diagnosis of facial deformities using historical portraits with genetic analysis of the degree of relatedness to determine whether there was a direct link. The researchers also investigated the genetic basis of the relationship.
