Despite the continued development and commercialization of various wearable electronic devices, such as smart bands, progress with these devices has been curbed by one major limitation, as they regularly need to be recharged. However, a new technology developed by a South Korean research team has become a hot topic, as it shows significant potential to overcome this limitation for wearable electronic devices.
A new study at Tel Aviv University reveals a possible defense mechanism developed by fireflies for protection against bats that might prey on them. According to the study, fireflies produce strong ultrasonic sounds - soundwaves that the human ear, and more importantly the fireflies themselves, cannot detect. The researchers hypothesize that these sounds are meant for the ears of bats, keeping them away from the poisonous fireflies, and thereby serving as a kind of 'musical armor'. The study was led by Prof.
Scientists from Russia and Germany studied the molecular composition of carbonaceous chondrites - the insoluble organic matter of the Murchison and Allende meteorites - in an attempt to identify their origin. Ultra-high resolution mass spectrometry revealed a wide diversity of chemical compositions and unexpected similarities between meteorites from different groups. The research was published in the Scientific Reports.
Manufacturing - Mighty Mo
Oak Ridge National Laboratory scientists proved molybdenum titanium carbide, a refractory metal alloy that can withstand extreme temperature environments, can also be crack free and dense when produced with electron beam powder bed fusion. Their finding indicates the material's viability in additive manufacturing.
In 2018, Kang-Kuen Ni and her lab earned the cover of Science with an impressive feat: They took two individual atoms, a sodium and a cesium, and forged them into a single dipolar molecule, sodium cesium.
Patients with a high number of genes most associated with pathways that lead to cell death in lung cancer are at increased risk of dying early from their disease, researchers report.
Also seemingly paradoxically, patients with high expression of this "21-gene cell death signature" the researchers have identified, have indicators that their immune system is attacking the cancer, like higher levels of cytotoxic T cells, which typically kill cancer.
Rates of prolonged visits for pediatric mental health emergency department (ED) visits increased over a decade, in contrast to non-mental health visits for which visit times remained stable, according to a study published in the journal Pediatrics. From 2005-2015, rates of ED visits lasting over six hours for children presenting for mental health issues jumped from 16 percent to nearly 25 percent, while rates of visits lasting over 12 hours increased from 5 percent to nearly 13 percent.
Researchers at the National Institutes of Health have developed a breath test that measures how well patients with methylmalonic acidemia (MMA) respond to receiving liver or combined liver and kidney transplantation. Researchers also used the test to assess the severity of the disease in people and help determine if they would benefit from surgical or experimental genomic therapies that target the liver. The study results were published in Genetics in Medicine.
PULLMAN, Wash. - The ability to control your own behavior, known as executive function, might not exist all in your head. A new theory proposes that it develops with many influences from outside the mind.
Buck Institute researchers have discovered and are developing a novel, non-invasive biomarker test that can be used to measure and track performance of senolytics: a class of drugs that selectively eliminate senescent cells. The discovery is expected to play a major role in efforts to develop treatments that would battle a myriad of chronic age-related conditions that range from arthritis to lung disease to Alzheimer's disease and glaucoma. This biomarker is a unique signaling lipid metabolite, normally exclusively intracellular, but is released when senescent cells are forced to die.
Aquaculture--the farming of fish, shellfish, and other aquatic animals for food--has reached unprecedented levels of growth in recent years, but largely without consideration of its impact on individual animals, finds a new analysis by a team of researchers.
SAN FRANCISCO, CA (April 2, 2021) -- In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building corals: species that appear identical to one another but are genetically distinct.
UNIVERSITY PARK, Pa. -- Like moths to a flame, spotted lanternflies are visually drawn toward and seemingly captivated by vertical objects such as utility poles, a behavior that could be valuable in predicting where the pests might be heading, according to entomologists in Penn State's College of Agricultural Sciences.
Acomprehensive review published in the journal Psychological Science re-examines previous work that claimed to show a direct link between early screen time and attention problems in children. Although other studies do not reflect these findings, the earlier research continues to be widely reported by the media.
HOUSTON - (April 2, 2021) - Understanding what drives food choices can help high-volume food service operations like universities reduce waste, according to a new study.
Researchers have concluded that food waste in places like university cafeterias is driven by how much people put on their plates, how familiar they are with what's on the menu and how much they like - or don't like - what they're served.
