An animal able to regenerate all of its organs even when it is dissected into three parts

The study was led by Prof Noa Shenkar, Prof Dorothee Huchon-Pupko, and Tal Gordon of Tel Aviv University’s School of Zoology at the George S. Wise Faculty of Life Sciences and the Steinhardt Museum of Natural History. The findings of this surprising discovery were published in the leading journal Frontiers in Cell and Developmental Biology. “It is an astounding discovery, as this is an animal that belongs to the phylum Chordata—animals with a dorsal cord—which also includes us humans,” explains Prof Noa Shenkar. “The ability to regenerate organs is common in the animal kingdom, and even among chordates you can find animals that regenerate organs, like the gecko who is able to grow a new tail. But not entire body systems. Here we found a chordate that can regenerate all of its organs even if it is separated into three pieces, with each […]

Majority of bird species in Americas could survive climate change, shows study

Monteverde-Arenal is one of 21 Important Bird and Biodiversity Areas (IBA) in Costa Rica. Credit: Sorin Vacaru Photography / Shutterstock.com Researchers show that the current network of Important Bird and Biodiversity Areas (IBAs) across the Americas should remain able to house the majority of bird species of conservation concern even after climate change. While individual bird species may shift their distribution range, 73% of species of conservation concern are likely to persist in at least half of the IBAs in which they occur, and 90% of species in at least a quarter of their current IBAs. This implies that future conservation efforts in the Caribbean and Central and South America can focus on expanding the current IBA network. A new study, led by Durham University and published in the journal Frontiers in Ecology and Evolution, investigates the impacts of potential climate change scenarios on the network of Important Bird and Biodiversity Areas (IBAs) across the Caribbean, and Central and South America. The research was carried out in collaboration with Senckenberg Biodiversity and Climate Research Centre, BirdLife International and the National Audubon Society. IBAs are […]

‘Fingerprint’ in blood markers may reveal heart attack in chest pain patients

By Conn Hastings, science writer Image: New Africa / Shutterstock When a patient with chest pain arrives at hospital, time is of the essence. Doctors must quickly rule heart attack in or out and start treatment as soon as possible. A new study reveals blood biomarkers that could help. By analyzing blood samples from patients with chest pain, researchers found a unique fingerprint of heart attack in the form of blood biomarkers. The results could help doctors to quickly diagnose and treat heart attack patients. A patient arrives at hospital with chest pain. Doctors suspect heart attack and rapid diagnosis is important, but the tests to confirm it can be invasive and it could easily be something else. Could a simple blood test help to non-invasively rule heart attack in or out? A new study in open access journal Frontiers in Cardiovascular Medicine certainly suggests so. The study identified telltale markers in the blood of heart attack patients that distinguished them from patients suffering chest pain with other causes. The researchers hope that the results will lead to new diagnostic tests for heart attacks.  Read original article Download original article (pdf) If you have ever suffered chest pain, the […]

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

By Colm Gorey, Frontiers science writer Image: wavebreakmedia/Shutterstock.com Researchers in Japan have developed a virtual reality platform that mimics the sensation of walking by stimulating their feet, all while sitting motionlessly. During testing, participants 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. Despite virtual reality (VR) technology being more affordable than ever, developers have yet to achieve a sense of full immersion in a digital world. Among the greatest challenges is making the user feel as if they are walking.   Now, researchers from the Toyohashi University of Technology and The University of Tokyo in Japan have published a paper to the journal Frontiers in Virtual Reality describing a custom-built platform that aims to replicate the sensation of walking in VR, all while sitting motionlessly in a chair. “Walking is a fundamental and fun activity for human in everyday life. Therefore, it is very worthy to provide a high-quality walking experience in a VR space,” says Yusuke Matsuda. Matsuda is a project assistant professor at the Department of Computer Science and Engineering at the Toyohashi University of […]
