In a world first, researchers from the University of Ottawa in collaboration with Israeli scientists have been able to create optical framed knots in the laboratory that could potentially be applied in modern technologies. Their work opens the door to new methods of distributing secret cryptographic keys - used to encrypt and decrypt data, ensure secure communication and protect private information. The group recently published their findings in Nature Communications.
Nagoya University researchers have synthesized a unique molecule with a surprising property: it can absorb near infrared light. The molecule is made only of hydrogen and carbon atoms and offers insights for making organic conductors and batteries. The details were published in the journal Nature Communications.
The eventual creation of replacement biological parts requires fully three-dimensional capabilities that two-dimensional and three-dimensional thin-film bioprinting cannot supply. Now, using a yield stress gel, Penn State engineers can place tiny aggregates of cells exactly where they want to build the complex shapes that will be necessary to replace bone, cartilage and other tissues.
An Edith Cowan University (ECU) study has revealed that a key blood marker of cancer could be used to select the most effective treatment for melanoma.
The discovery, which has the potential to improve melanoma survival rates, was published today in Clinical Cancer Research, a journal of the American Association for Cancer Research.
When COVID closed down their lab in March, a team from the University of Essex turned to computational approaches to understand what makes some plants better adapted to transform light and carbon dioxide into yield through photosynthesis. They published their findings in the journal Frontiers of Plant Science.
Global stimulus plans for economic recovery after the pandemic could easily cover climate-friendly policies, suggests new study.
Governments worldwide are planning stimulus packages to boost the economy following the disruptions caused by the COVID-19 pandemic. So far, more than $12 trillion USD have been pledged in such packages. This response is three times larger than the 2008-2009 global financial crisis recovery spending, and represents around 15 percent of global gross domestic product (GDP).
Boston, MA -- A new study examines whether the "race multiplier" correction factor for Black patients, used when estimating kidney function, may contribute to disparities in care for these patients with chronic kidney disease (CKD). Black patients with CKD have worse outcomes than other racial groups, including higher rates of anemia and hypertension, longer waits for referral to nephrology, and poorer access to transplantation.
UNIVERSITY PARK, Pa. -- RADAR satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements.
WEST LAFAYETTE, Ind. -- A rectangular robot as tiny as a few human hairs can travel throughout a colon by doing back flips, Purdue University engineers have demonstrated in live animal models.
Why the back flips? Because the goal is to use these robots to transport drugs in humans, whose colons and other organs have rough terrain. Side flips work, too.
When southern Rocky Mountain forests are viewed from a distance these days, it may not look like much is left. Large swaths of dead, standing Engelmann spruce trees tell the tale of a severe regional spruce beetle epidemic in its waning stages. But among those dead trees, researchers have found good news. Zoom-in to the ground cover of these forests and there is life, even more abundant because of this disturbance.
LOWELL, Mass. - Former Vice President Joe Biden has a 10-point lead over President Donald Trump in the contest for the White House in a new national poll of likely voters released today by the UMass Lowell Center for Public Opinion.
Including the minor party candidates on the ballot, Biden leads with 53 percent of likely voters, Trump has 43 percent, other candidates are at 2 percent and only 3 percent of likely voters say they are still undecided, according to the independent, nonpartisan poll.
NEW YORK - October 15, 2020 - In a randomized clinical trial, SCOPE II, a new self-expanding bioprosthetic valve used in transcatheter aortic valve replacement (TAVR) failed to demonstrate non-inferiority compared to an existing self-expanding valve.
Findings were reported today at TCT Connect, the 32nd annual scientific symposium of the Cardiovascular Research Foundation (CRF). TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine. The study was also published simultaneously in Circulation.
NEW YORK - October 15, 2020 - The REFLECT II randomized clinical trial evaluating the safety and efficacy of a device designed to reduce cerebral embolization and ischemic stroke, complications of transcatheter aortic valve replacement (TAVR), found that the device met the primary safety endpoint compared to historical controls but did not demonstrate superiority of the device for the primary hierarchical efficacy endpoint.
The COVID-19 pandemic has been linked to an estimated 110,000 firearm purchases in California and increases in individuals' worries about violence, according to a new study by the UC Davis Violence Prevention Program (VPRP). The study looked at the intersection of the coronavirus pandemic and violence-related harms in the state.
Irvine, Calif., Oct. 14, 2020 -- An international team of climate experts, including Earth system scientists at the University of California, Irvine, today released an assessment of carbon dioxide emissions by industry, transportation and other sectors from January through June, showing that this year's pandemic lockdowns resulted in a 9 percent decline from 2019 levels.
