A survey of maritime infrastructure engineers by University of Rhode Island researchers found that the rising sea level is often not factored into designs of ports, breakwaters, fishing piers and other coastal infrastructure.
“If we’re making decisions about infrastructure today and expect it to be serviceable for the next 50 to 75 years, we should be thinking about what the environmental conditions will be like towards the end of the infrastructure’s life,” said Austin Becker, URI associate professor of marine affairs, who studies how ports are preparing for climate change. “And we know that things are going to be very different along our coasts in the coming years.”
In 2019, Becker and graduate student Benjamin Sweeney surveyed 85 engineers at consulting firms, port authorities and government agencies with experience working on port infrastructure projects in the United States. They found that 64% do not have a policy or planning document
In the era of electric cars, machine learning and ultra-efficient vehicles for space travel, computers and hardware are operating faster and more efficiently. But this increase in power comes with a trade-off: They get superhot.
To counter this, University of Central Florida researchers are developing a way for large machines to “breathe” in and out cooling blasts of water to keep their systems from overheating.
The findings are detailed in a recent study in the journal Physical Review Fluids.
The process is much like how humans and some animals breath in air to cool their bodies down, except in this case, the machines would be breathing in cool blasts of water, says Khan Rabbi, a doctoral candidate in UCF’s Department of Mechanical and Aerospace Engineering and lead author of the study.
“Our technique used a pulsed water-jet to cool a hot titanium surface,” Rabbi says. “The more water we
A new study shows that the vast majority of patients who visited the Ruth and Harry Roman Emergency Department at Cedars-Sinai with suspected COVID-19 (novel coronavirus) symptoms, and who were treated and sent home to recuperate, recovered within a week.
The study, published by the Journal of the American College of Emergency Physicians Open, showed that none of those patients died from the virus and fewer than 1% required intensive care.
“When the pandemic began there was minimal evidence to guide us as to who should be hospitalized and who could be sent home,” said Sam Torbati, MD, co-chair and medical director of the Ruth and Harry Roman Emergency Department at Cedars-Sinai. “In real time, we began developing our criteria for who needed hospitalization for monitoring, intensive care, and who could recover at home. And this study shows our patients received the appropriate level of care.”
Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.
Led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, the team published their results in ACS Applied Materials & Interfaces.
“In this article, we report a simple yet universally applicable fabrication technique with the use of a novel sintering aid layer to enable direct printing for on-body sensors,” said first author Ling Zhang, a researcher in the Harbin Institute of Technology in China and in Cheng’s laboratory.
Cheng and his colleagues previously developed flexible printed circuit boards for use in wearable sensors, but printing directly on skin has been hindered by
Researchers from Cornell University have created an earphone system that can track a wearer’s facial expressions even when they’re wearing a mask. C-Face can monitor cheek contours and convert the wearer’s expression into an emoji. That could allow people to, for instance, convey their emotions during group calls without having to turn on their webcam.
“This device is simpler, less obtrusive and more capable than any existing ear-mounted wearable technologies for tracking facial expressions,” Cheng Zhang, director of Cornell’s SciFi Lab and senior author of a paper on C-Face, said in a statement. “In previous wearable technology aiming to recognize facial expressions, most solutions needed to attach sensors on the face and even with so much instrumentation, they could only recognize a limited set of discrete facial expressions.”
The earphone uses two RGB cameras that are positioned below each ear. They can record changes in cheek contours when the wearer’s
Are you still washing your hands often and cleaning your phone screen and other gadgets regularly, or has that habit slipped? With the COVID-19 virus still burning its way through the population, it’s a bad time to let good habits slide, especially given the results of a new study by Australian researchers.
The findings, published in Virology Journal, suggest that the SARS-Cov-2 virus responsible for COVID-19 can last for almost a month on glass, stainless steel, and both paper and polymer banknotes if kept at ambient temperature and humidity (20 °C and 50 percent RH).

According to the paper, “the persistence of SARS-COV-2 on glass and vinyl (both common screen and screen protector materials, suggest that touchscreen devices may provide a potential source of transmission, and should regularly be disinfected especially in multi-user environments.”
In a groundbreaking new study, researchers at the University of Minnesota, in collaboration with the U.S. Army Combat Capabilities Development Command Soldier Center, have 3D printed unique fluid channels at the micron scale that could automate production of diagnostics, sensors, and assays used for a variety of medical tests and other applications.
The team is the first to 3D print these structures on a curved surface, providing the initial step for someday printing them directly on the skin for real-time sensing of bodily fluids. The research is published in Science Advances.
Microfluidics is a rapidly growing field involving the control of fluid flows at the micron scale (one millionth of a meter). Microfluidics are used in a wide range of application areas including environmental sensing, medical diagnostics (such as COVID-19 and cancer), pregnancy testing, drug screening and delivery, and other biological assays.
The global microfluidics market value is currently
“I have taken pains to verify this assertion, and have found it true that frogs, toads, and newts are absent from most oceanic islands”—thus states Charles Darwin in his well-known work “On the Origin of Species.” For a long time, this observation by the famous naturalist also held true for the Galápagos Islands, which are inextricably linked to his name. “This only changed with the arrival of Fowler’s snouted treefrog Scinax quinquefasciatus on the archipelago in 1997 or 1998,” explains Dr. habil. Raffael Ernst of the Senckenberg Natural History Collections in Dresden, and he continues, “In our study, we examined the interactions of this newcomer with the local, primarily endemic fauna on Galápagos.”
Ernst and his colleagues were curious to find out what role this 33-to-38-millimeter-long frog plays within the island fauna’s food
