The androgen receptor is the primary driver of the initiation and growth of prostate cancer, the second-leading cause of death in men. Looking to have a better understanding of how the androgen receptor works in cancer, researchers at Baylor College of Medicine conducted comprehensive studies of the 3-D structure of the receptor.
Farmland bird species are declining over most of Europe. Birds breeding on the ground, are particularly vulnerable because they are exposed to mechanical operations, like ploughing and sowing, which take place in spring and often accidentally destroy nests.
Locating nests on the ground is challenging for the human eye, and highly time-consuming
The catastrophic effects of global environmental degradation, health deterioration and diminishing energy resources are demanding remedy measures aimed at environmental conservation, health interventions and harnessing of the abundant and renewable energy resources. Consequently, sensors and renewable energy harnessing systems have emerged as worthwhile solutions to the existent challenges. However, conventional sensors and renewable energy harnessing systems have presented diminished efficiency and performance to be improved.
Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless communications (6G/7G), security systems, biomedicine, and even art history. A new device for controlling T-rays using a specially designed 'metasurface' with properties not found in nature could begin to realize this potential.
The findings are published in the peer-reviewed journal Optics Express on July 13th, 2020.
Research led by scientists at The Australian National University (ANU) could lead to major improvements in crop production.
The study shows a new way to help study and ramp up photosynthesis. The breakthrough is based on revisiting an original, billion-year-old strategy in plants.
It looks specifically at rubisco activity - a crucial part of the process according to co-author Professor Spencer Whitney from the ARC Centre of Excellence for Translational Photosynthesis at ANU.
Medicated chewing gum has been recognised as a new advanced drug delivery method but currently there is no gold standard for testing drug release from chewing gum in vitro. New research has shown a chewing robot with built-in humanoid jaws could provide opportunities for pharmaceutical companies to develop medicated chewing gum.
Researchers of Peter the Great St.Petersburg Polytechnic University(SPbPU) in collaboration with colleagues from Tsinghua University (China) developed a new dynamic light scattering method to determine the sizes of circulating immune complexes in blood serum.
Especially activities in the field of artificial intelligence, like teaching robots to walk or precise automatic image recognition, demand ever more powerful, yet at the same time more economical computer chips. While the optimization of conventional microelectronics is slowly reaching its physical limits, nature offers us a blueprint how information can be processed and stored quickly and efficiently: our own brain.
Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of charge between gallium and arsenic atoms acts back on their motions via electric interactions.
Nine out of 10 U.S. men ages 18 to 35 support health care providers asking about intimate partner violence, according to new survey analysis. Data from a 2014 nationally representative survey showed that while most men support health care-based intimate partner violence screenings, only about 10 percent reported being asked by their doctor. Men who reported lower levels of education were most likely to be asked, but support for screenings varied by race and past experience with such violence. Black non-Hispanic men were less likely to think doctors should ask.
WASHINGTON (July 14, 2020)--Smartphone owners who unlock their devices with knock codes aren't as safe as they think, according to researchers from New Jersey Institute of Technology, the George Washington University and Ruhr University Bochum.
Knock codes work by letting people select patterns to tap on a phone's locked screen. LG popularized the method in 2014, and now there are approximately 700,000 people using this method in the U.S. alone, along with one million downloads worldwide of clone applications for Google Android devices generally, the researchers said.
TORONTO, July 14, 2020 - Climate change and an increase in disturbed bee habitats from expanding agriculture and development in northeastern North America over the last 30 years are likely responsible for a 94 per cent loss of plant-pollinator networks, York University researchers found.
The authors of this study developed a single risk score derived from multiple social determinants of health that predicts county-level cardiovascular disease mortality. Using data culled from government resources, they identified U.S. counties with a high risk of CVD based on a three-year average mortality rate.
This study analyzes patterns of participation in the Comprehensive Primary Care Plus initiative which is the largest voluntary primary care payment and delivery reform model tested to date. Of the nearly 20,000 primary care practices within the 18 regions selected by the Centers for Medicare and Medicaid Services for CPC+ implementation, 22 percent applied to participate. CMS accepted all applicants that met their minimum criteria, reflecting 15 percent of all primary care practices in the regions. Participation rates varied across the 18 regions from 2 percent to 34 percent.
Propagate light through any kind of medium - be it free space or biological tissue - and light will scatter. Robustness to scattering is a common requirement for communications and for imaging systems. Structured light, with its use of projected patterns, is resistant to scattering, and has therefore emerged as a versatile tool. In particular, modes of structured light carrying orbital angular momentum (OAM) have attracted significant attention for applications in biomedical imaging.
