Researchers' VR walking simulator feels surprisingly close to the real thing

Eurekalert - Apr 21 2021 - 00:04
Researchers in Japan have developed a virtual reality platform that mimics the sensation of walking by stimulating their hands and feet, all while sitting motionlessly. During testing, participants using the platform experiencing a digital world through a first-person perspective found it enhanced the simulation of walking. However, those who saw themselves from a third-person perspective felt it impaired the sensation of movement.

Walk the dinosaur! New biomechanical model shows Tyrannosaurus rex in a swinging gait

Eurekalert - Apr 21 2021 - 00:04
Researchers from the Netherlands have created a new approach to envision how dinosaurs walked. By modeling a T. rex tail as a suspension bridge, the scientists formed a new idea of the animal's walking speed. Trix, the tyrannosaur from Naturalis museum in the Netherlands, probably strolled slower - but with more spring in its step - than assumed. This is a first step towards more realistic dinosaur motion.

A good night's sleep could do wonders for your sex life

Eurekalert - Apr 21 2021 - 00:04
The importance of getting a good night's sleep cannot be overstated. Lack of sleep can lead to a number of health problems and affect a woman's overall quality of life. A new study suggests that insufficient quality sleep also may lead to problems in the bedroom in the form of female sexual dysfunction. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

NASA NeMO-Net video game helps researchers understand global coral reef health

Eurekalert - Apr 21 2021 - 00:04
A new study has demonstrated how video games can be used as a citizen science approach to train artificial intelligence tools, with data contributing towards coral reef conservation efforts. The NeMO-Net video game, designed by researchers at NASA's Ames Research Center in California's Silicon Valley and led by principal investigator Dr Ved Chirayath, provides an educational and intuitive tool for players to learn about and explore coral reef ecosystems, whilst also bringing marine conservation research to wider audiences.

Mobility in terrestrial and underwater wireless sensor networks

Eurekalert - Apr 21 2021 - 00:04
A Wireless Sensor Network--a set of sensor nodes placed in different locations that sense their surroundings and transmit sensed data--can have a range of applications related to the environment, healthcare, transportation, security, and other areas. An analysis of published research in the International Journal of Communication Systems provides an overview of the ability of "mobile elements" to improve terrestrial and underwater Wireless Sensor Networks.

Gaps in genetic knowledge affect kiwi conservation efforts

Eurekalert - Apr 21 2021 - 00:04
Kiwi are iconic birds that have been severely impacted by deforestation and predation from invasive mammals since the arrival of humans in New Zealand. The remaining kiwi can be split into 14 clusters that are now treated as separate conservation management units. A review published in Ibis examines the latest information on kiwi genetics to investigate the legitimacy for maintaining these differences.

Study reveals the complexity of microplastic pollution

Eurekalert - Apr 21 2021 - 00:04
Microplastics--small plastic pieces less than 5 millimeters in length--are ubiquitous in the environment, and they can have significant effects on wildlife. A new study published in Environmental Toxicology and Chemistry reveals that there are multiple impacts of different microplastics--with varying sizes, shapes, and chemical makeup--to the survival, growth, and development of larval fathead minnows, an important prey species in lakes and rivers in North America.

New analysis addresses fear of cancer recurrence

Eurekalert - Apr 21 2021 - 00:04
After undergoing treatment for cancer, patients may worry that the disease will recur. An analysis of studies published in Psycho-Oncology indicates that fear of cancer recurrence may lead to an increased use of healthcare resources -- such as more visits to see physicians and greater use of medications -- by cancer survivors.

New insights on inflammation in COVID-19

Eurekalert - Apr 21 2021 - 00:04
Severe cases of COVID-19 can involve extensive inflammation in the body, and clinicians have wondered if this state is similar to what are called cytokine storm syndromes, in which the immune system produces too many inflammatory signals that can sometimes lead to organ failure and death. A new study published in Arthritis & Rheumatology indicates that different markers in the blood clearly differentiate excessive inflammation in critical COVID-19 from cytokine storm syndromes.

Enhancing virtual walking sensation for seated observer using walking avatars

Eurekalert - Apr 21 2021 - 00:04
Researchers at the Toyohashi University of Technology and the University of Tokyo have developed a virtual walking system for seated observers and have revealed that walking self-avatars improve the illusory walking sensation by integrating foot-vibration simulating footsteps. The walking-avatar is presented in the first-person and mirrored perspectives, to induce a sense of body ownership. This system provides a virtual walking experience to people with walking disabilities.

Vibrational microscopy goes super resolution

Eurekalert - Apr 20 2021 - 00:04
True super-resolution imaging beyond the diffraction limit remains a major challenge for far-field Raman microscopy especially in biological applications. Harnessing Stimulated Raman Excited Fluorescence (SREF) as an ultrasensitive vibrational contrast, a team at Columbia University has recently invented a novel super-resolution vibrational microscopy. Their new method opens up super-resolution, nanometer-spectral-resolution multicolor vibrational imaging of biological systems.
