Today, there are many emerging applications for small satellite constellations, ranging from space-borne networks to environmental monitoring. However, small satellites have special needs when it comes to transmitter (TX) technology. For one, they have stringent limitations on power consumption as they draw energy from solar panels and cannot easily dissipate generated heat. Moreover, small satellites need to communicate with fast-moving targets that can be over a thousand kilometers away. Thus, they require efficient and precise beam steering capabilities to direct most of the transmitted power ...

A database updated in 2022 reported around 4,852 active satellites orbiting the earth. These satellites serve many different purposes in space, from GPS and weather tracking to military reconnaissance and early warning systems. Given the wide array of uses for satellites, especially in low Earth orbit (LEO), researchers are constantly trying to develop better ones. In this regard, small satellites have a lot of potential. They can reduce launch costs and increase the number of satellites in orbit, providing a better network with wider coverage. ...

ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called “chloroplast ATP synthase” (CFoCF1). To control ATP production under varying light conditions, the enzyme uses a redox regulatory mechanism that modifies the ATP synthesis activity in response to changes in the redox state of cysteine (Cys) residues, which exist as dithiols under reducing (light) conditions, but forms a disulfide bond under oxidizing (dark) conditions. ...

Bicycles whirr by, students rush to class, staff and faculty are grabbing lunch or coffee on the go — and sheep graze the grassy knolls among the traffic, bleating every now and then. The grazing is their job. The 25 wooly sheep who seasonally — for the past two years — leave their University of California, Davis, barns to nibble on lawns at various central campus locations, are doing much more than mowing, fertilizing and improving the ecosystem. The sheep also are improving people’s mental health. The sheep — four breeds of Suffolk, Hampshire, Southdown and Dorset — first took on this role in 2021, when COVID-19 ...

ITHACA, N.Y. – Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to a research team co-led by a Cornell University astronomer. In a paper published in Nature Communications, visiting planetary scientist Alberto Fairén, and an international team of researchers, claim that ancient organic material in Martian rocks could be difficult, if not impossible, to detect with current instruments and techniques. Fairén – also a research professor at the Center ...

Different cell types—say, heart, liver, blood, and sperm cells—possess characteristics that help them carry out their unique jobs in the body. In general, those characteristics are hard-wired. Without intervention, a heart cell won’t spontaneously transform into a liver cell. Yet researchers from the University of Pennsylvania School of Veterinary Medicine, working with collaborators from the University of Texas at San Antonio and Texas Biomedical Research Institute, have prompted marmoset blood cells to acquire the flexibility of stem cells. Then they directed those stem cells to take on the characteristics of sperm ...

When Prof. Markus Scholz, who teaches archaeology and the history of Roman provinces at Goethe University, returned to Bad Ems toward the end of the excavation work, he was astonished: After all, all the photos sent by his colleague Frederic Auth showed but a few pieces of wood. Not surprisingly, Scholz was ill-prepared for what he saw next: a wooden defense construction consisting of sharpened wooden stakes, designed to prevent the enemy’s approach. The martial-looking structure was intended to deter enemies from attacking the camp. Such installations – ...

Living organisms have a knack for persisting in the face of challenges. For instance, when genes malfunction, organisms may be able to compensate by activating redundant genes with similar functions, called paralogs. One example of such compensation are two genes of the muscleblind-like (MBNL) family of RNA-binding proteins that lose their function in Myotonic Dystrophy Type 1, the most common cause of adult-onset muscular dystrophy. Loss of MBNL1 increases the levels of its paralog MBNL2 in tissues where protein expression is low, allowing MBNL2 to functionally compensate for MBNL1 loss. In animal models, loss of one paralog results in ...

Thanhvu Nguyen, Assistant Professor, Computer Science, is set to receive funding for the project: "CAREER: NeuralSAT: A Constraint-Solving Framework for Verifying Deep Neural Networks."  Deep Neural Networks (DNNs) have emerged as an effective approach to tackling real-world problems. However, just like traditional software, DNNs can have bugs and be attacked. This naturally raises the question of how DNNs should be tested, validated, and ultimately verified to meet the ...

AMES, Iowa – Let’s see, thought James Vary, how can we have a little fun with the name of our $1 million nuclear physics project?   Hmm, can we work in the term hack?   So, it’s “Nuclei and Hadrons with Quantum Computers.” Or, “NuHaQ,” for short.   “It’s a takeoff on ‘hack,’” said Vary, an Iowa State University professor of physics and astronomy and leader of a new project supported by a three-year, $1 million grant from the U.S. Department of Energy. In academic computing circles, “to be a good hacker is a positive compliment. Hackers ...

INFORMS Journal Organization Science New Study Key Takeaways: Choosing who to speak to greatly impacts how ideas are heard and implemented in the workplace. Employees who speak to managers or bosses who have the authority and resources to address an issue, led to a 12%-15% increase in implementing ideas and subsequent sales performance. Speaking to peers was associated with a 10% decrease in implemented ideas and subsequent sales performance.   BALTIMORE, MD, February 21, 2023 – Is speaking up at work worth it? New research in the INFORMS journal Organization Science finds that new ideas can be heard and implemented in the office, but it depends on who employees talk to. “There ...

Researchers from the Icahn School of Medicine at Mount Sinai have generated the first induced pluripotent stem cells (iPSCs) from bats, gaining valuable insights into the close relationship between bats and viruses. This research opens the door to studying how viruses like SARS-CoV-2, which causes COVID-19, survive, spread, and evade the immune system through molecular adaptations to new hosts. The team’s findings, published February 21 in Cell, may also shed light on the unique properties of bats that underlie their remarkable defenses against aging and cancer. “Our study suggests that bats have evolved mechanisms to tolerate a large ...

WASHINGTON, Feb. 21, 2023 – It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don’t have access to clean drinking water. As for the pollution of potable and natural water sources, one of the main culprits is arsenic, an abundant and toxic element in the earth’s crust. Arsenic is currently known as the cause of groundwater contamination in more than 100 countries – and can produce life-threatening diseases, especially for populations in developing ...

In 2015, scientists for the first time detected gravitational waves, ripples in space-time that occur when major cosmic events—like the collision and merging of two black holes—disrupt the cosmos. The observation of these waves confirmed Einstein’s theory of general relativity, which predicted such waves would occur if space-time worked as he believed it did. In the seven years since, nearly 100 merging black holes have been detected by observing the gravitational waves that these extraterrestrial events emit. Now, thanks to new research from a team of 14 led by Caltech ...

About The Study: Sustained low-wage earning in midlife may be associated with elevated mortality risk and excess deaths, especially when experienced alongside unstable employment, according to the results of this study including 4,000 workers. If causal, the findings suggest that social and economic policies that improve the financial standing of low-wage workers (e.g., minimum wage laws) could improve mortality outcomes.  Authors: Katrina L. Kezios, Ph.D., of Columbia University in New York, is the corresponding author.
