  • Volunteer crew begins an eight-month mission on Hawaii’s make-believe Mars

    Six volunteers – including two with connections to Washington state – have begun eight months of being cooped up in a Hawaii habitat that’s meant to simulate life on Mars. The Hawaii Space Exploration Analog and Simulation project, known as HI-SEAS, is one of several long-running experiments that use earthly environments as a training ground for future Red Planet expeditions. This is the fifth simulated mission to be staged on the slopes of Mauna Loa on Hawaii’s Big Island, 8,200 feet above sea level. The University of Hawaii at Manoa has conducted the simulations since 2012, thanks to $1.2 million in NASA funding.… Read More

  • Here's how clever people become science deniers

    Conspiracy theorists, people against vaccination and those who believe climate change is not happening are typically interested in science, but process information in a different way, psychologists say. Science sceptics tend to follow a particular argument or message by cherry-picking the information that supports their established view, psychologist Matthew Hornsey of the University of Queensland, Australia, argues in a paper presented at a meeting of the Society for Personality and Social Psychology in San Antonio, US.

  • A robotic implant that hugs your heart could help it keep beating

    A soft robotic sleeve made of silicone could help a human heart keep beating, according to a new report published Wednesday. For the millions suffering from heart failure and other cardiac issues, that could mean a beating heart without the blood clotting complications of the current mechanical heart pumps called ventricular assist devices, or VADs, according to a statement from the National University of Ireland Galway. The research, published in the journal Science Translational Medicine , was led by Ellen Roche of that university. It took place at Harvard and at Boston Children's Hospital. SEE ALSO: This Albert Einstein robot can help you learn science Made of soft fibers including silicone, the robotic sleeve bonds itself to the heart by wrapping around it, essentially becoming part of the beating organ as it moves in synch with it. In doing this, it provides circulatory support for hearts not functioning properly, supporting blood flow through a sleeve that manages to not come in contact with blood, as explained in the study. This design marks a departure from the way VADs support heart function, as those devices must interfere with blood flow in order to assist in healthy pumping of the heart. "Using current VADs, the heart and one or both of the great vessels are cannulated, blood is removed from the heart, and blood is then pumped into the aorta or pulmonary artery," the researchers write. "In this scenario, the VAD assumes the function of one or both of the failing ventricles of the heart." But clotting complications that can require potentially risky blood thinners make VADs a less than ideal solution for those suffering heart failure.  A) How muscle fibers are oriented right outside the heart inspired the design of the VAD. B) The soft fibers of the robotic sleeve can compress and twist along with the motion of the heart. C) Silicone casting was used to produce the new implantable device. D) 3-D printing was also used to construct the implantable robot. E) These are areas of the heart which the robotic sleeve can wrap around. Image: American Association for the Advancement of Science Researchers tested out the new robotic sleeve using a pig heart to examine how effectively it supports heart function. "The soft robotic sleeve we describe took inspiration from native heart muscle and was designed to augment cardiac function by closely replicating it, instead of disrupting it," the researchers wrote. In this way, soft robotic techniques were used to "replicate the heart’s motion." The study explains that the broader field of robotics is facing new developments as softer materials are being used in innovative new ways. "However, the field is being transformed by a new wave of soft robots that are constructed using a combination of elastomers, fibers, and other filler materials," the study explains. "This approach provides opportunities to create robots that are well suited for intimate interactions with humans and with tunable material properties to match biological tissues." Such designs in medical robots can provide patients with more options, such as with the sleeve that wraps around the heart. "The sleeve can be customized for each patient," Dr. Roche said in the statement. The parts of the heart involved, and the strength of the pressure the sleeve uses, can be adjusted according to a patient's individual case. Robots have been used for a lot of things, from being a personal writing machine to delivering food to your doorstep, but helping a person's heart pump makes them even more useful.
