When faced with conditions that are too dry, salty, or cold, most plants try to conserve resources. They send out fewer leaves and roots and close up their pores to hold in water. If circumstances don’t improve, they eventually die.
ORNL researchers have developed and tested novel small-molecule antivirals in an effort to design new drugs to treat COVID-19. The so called hybrid inhibitor molecules are made from repurposed drugs used to treat hepatitis C and the original coronavirus outbreak in the early 2000s. The experimental research results show the molecules are similarly as effective as some of the leading drugs on the market today.
Scattered across our Milky Way galaxy are tens of millions of black holes —immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black holes are dark by definition, except on the rare occasions when they feed.
The research used in-depth interviews collected between 2019 and 2021 with 84 young adults who were minors in the mid-2000s to draw conclusions and then policy implications.
The neurotransmitter dopamine, famous for its role in reward, is also involved in recognizing emotions, according to new research published in JNeurosci.
Recent studies finding that there is an overdiagnosis of melanoma are a significant cause for concern. However, while many pathologists agree overdiagnosis of skin cancer happens, they don’t change diagnosis behavior.
妙佑医疗国际(Mayo Clinic) 研究人员提出了一种新的计算模型，用于在阿尔茨海默病症状与脑解剖结构之间建立起映射关系。该模型是通过将机器学习技术应用于患者大脑成像数据而开发的。这个模型利用大脑的完整功能，而不是特定的大脑区域或网络来解释脑解剖结构与心理过程之间的关系。研究结果已发表在《自然通讯》杂志上。

مدينة روتشستر، ولاية مينيسوتا- اقترح باحثو مايو كلينك نموذجًا جديدًا لرسم خرائط أعراض داء الزهايمر في تشريح الدماغ. وتم تطوير هذا النموذج عبر إجراء التعلم الآلي على بيانات تصوير دماغ المرضى، حيث يستخدم الوظيفة الكاملة للدماغ بدلًا من استخدام مناطق أو شبكات دماغية محددة لشرح العلاقة بين تشريح الدماغ ومعالجة الدماغ للعمليات. وتم نشر النتائج في نيتشر كوميونيكيشنز.
Pesquisadores da Mayo Clinic propuseram um novo modelo para mapear os sintomas da doença de Alzheimer na anatomia do cérebro. Esse modelo foi desenvolvido aplicando o processo de aprendizagem de uma máquina a dados de imagens de cérebros de pacientes.
Los investigadores de Mayo Clinic propusieron un nuevo modelo para hacer un mapa de los síntomas de la enfermedad de Alzheimer en la anatomía cerebral. El modelo se creó mediante la aplicación de aprendizaje automático a los datos de imágenes cerebrales de los pacientes.
High school students who focus on one sport are more likely to get injured or suffer from burnout. But new research from the University of Georgia suggests their motivation for specializing in one sport is pure: love of the game and competition.
Every plant, animal or other nucleus-containing cell also harbors an array of miniature “organs” that perform essential functions for the cell.
An international research group led by Professor Toru Takumi (Senior Visiting Scientist, RIKEN Center for Biosystems Dynamics Research) and Researcher Chia-wen Lin at Kobe University Graduate School of Medicine has shown that idiopathic autism*1 is caused by epigenetic*2 abnormalities in hematopoietic cells during fetal development, which results in immune dysregulation in the brain and gut.
A new study from Binghamton University, State University of New York proves the correct dosage for ultraviolet disinfection against COVID.
A study of nearly 9,000 children found those who eat a vegetarian diet had similar measures of growth and nutrition compared to children who eat meat.
Public participation in environmental decisions in Ontario declined significantly during the COVID-19 pandemic, raising concerns the system failed to protect a core value at a time of crisis.
A new study has found that older adults are no more likely to fall for fake news than younger adults, with age-related susceptibility to deceptive news evident only among those categorized as the “oldest old.”
