Planning algorithm enables high-performance flight
2023-08-23
A tailsitter is a fixed-wing aircraft that takes off and lands vertically (it sits on its tail on the landing pad), and then tilts horizontally for forward flight. Faster and more efficient than quadcopter drones, these versatile aircraft can fly over a large area like an airplane but also hover like a helicopter, making them well-suited for tasks like search-and-rescue or parcel delivery.
MIT researchers have developed new algorithms for trajectory planning and control of a tailsitter that take advantage of the maneuverability and versatility of this type of aircraft. Their algorithms ...
Clinical trial studying possible new treatment option for patients with NAFLD
2023-08-23
According to the National Institutes of Health, approximately 24% of adults in the United States have nonalcoholic fatty liver disease (NAFLD), an umbrella term for a range of liver conditions affecting people who drink little to no alcohol that can lead to cirrhosis, liver cancer and liver failure.
Currently, there are no medications approved by the U.S. Food and Drug Administration (FDA) to treat NAFLD.
A recent $9.57 million grant awarded to researchers with the UC San Diego NAFLD Research Center at University of California San Diego School of Medicine will support a clinical trial to study a new treatment option for patients ...

Health claims and doses of fish oil supplements
2023-08-23
About The Study: The results of this study suggest that the majority of fish oil supplement labels make health claims, usually in the form of structure/function claims, that imply a health benefit across a variety of organ systems despite a lack of trial data showing efficacy. Significant heterogeneity exists in the daily dose of eicosapentaenoic acid + docosahexaenoic acid in available supplements, leading to potential variability in safety and efficacy between supplements.

Study: Atmospheric circulation weakens following volcanic eruptions
2023-08-23
The Pacific Ocean covers 32% of Earth’s surface area, more than all the land combined. Unsurprisingly, its activity affects conditions around the globe.
Periodic variations in the ocean’s water temperature and winds, called the El Niño–Southern Oscillation, are a major meteorologic force. Scientists know that human activity is affecting this system, but are still determining the extent. A new study in Nature has revealed that the atmospheric component of this system — ...

2023-08-23
Researchers at UC San Francisco and UC Berkeley have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.
It is the first time that either speech or facial expressions have been synthesized from brain signals. The system can also decode these signals into text at nearly 80 words per minute, a vast improvement over commercially available technology.
Edward Chang, MD, chair of neurological surgery at UCSF, who has worked on the technology, known as a brain computer interface, or BCI, for more than a decade, hopes this latest research breakthrough, appearing Aug. 23, 2023, ...
Wildlife overflow enriches biodiversity beyond park boundaries
2023-08-23
New research has discovered the power of large national parks to not only enhance bird diversity inside their borders but boost mammal diversity in nearby unprotected areas.
The University of Queensland’s Dr Matthew Luskin said the study, which involved using more than 2,000 cameras and bird surveys across Southeast Asia, reveals for the first time the benefit of expanding protected land areas around the globe beyond park boundaries.
“Protected area expansions are often a difficult and expensive process, but our results show they are absolutely worth it,” Dr Luskin said.
“We ...
Graphene: More magic starts when flatness ends
2023-08-23
Researchers from The University of Manchester and the University of Warwick finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory.
A decade ago, scientists at The University of Manchester demonstrated that graphene is permeable to protons, nuclei of hydrogen atoms. The unexpected result started a debate in the community because theory predicted that it would take billions of years for a proton to permeate through graphene’s dense crystalline structure. This had led to suggestions that protons permeate not through the crystal lattice itself, ...
Researchers fully sequence the Y chromosome for the first time
2023-08-23
What was once the final frontier of the human genome — the Y chromosome — has just been mapped out in its entirety.
Led by the National Human Genome Research Institute (NHGRI), a team of researchers at the National Institute of Standards and Technology (NIST) and many other organizations used advanced sequencing technologies to read out the full DNA sequence of the Y chromosome — a region of the genome that typically drives male reproductive development. The results of a study ...
New research shows how cancer rewires a key immune pathway to spread
2023-08-23
A study led by researchers at Memorial Sloan Kettering Cancer Center (MSK) and Weill Cornell Medicine discovered a new relationship between cancer cells and the immune system, and shows how cancer can selfishly hijack a normally helpful immune pathway.
Usually, activation of this key immune pathway — called the STING pathway — triggers a strong inflammatory response that protects the body from foreign and unhealthy cells. But prolonged activation of the same pathway leads to a desensitization and ultimately to a “rewiring” of cellular signaling, which aids and abets cancer’s spread, the researchers found.
“You might think of ...

Adding immunity to human kidney-on-a-chip advances cancer drug testing
2023-08-23
By Benjamin Boettner
(Boston) — A growing repertoire of cell and molecule-based immunotherapies is offering patients with indomitable cancers new hope by mobilizing their immune systems against tumor cells. An emerging class of such immunotherapeutics, known as T cell bispecific antibodies (TCBs), are of growing importance with several TCBs that the U.S. Food and Drug Administration (FDA) approved for the treatment of leukemias, lymphomas, and myelomas. These antibody drugs label tumor cells with one of their ends, and attract immune cells with another end to coerce them into tumor cell killing.
One major challenge in the development of TCBs and other immunotherapy ...
Fungus gnats as pollinators not pests
2023-08-23
Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded ...
Solar powered irrigation: a game-changer for small-scale farms in sub-Saharan Africa
2023-08-23
In sub-Saharan Africa 80% of agricultural production is from smallholder farmers, who face constraints on increasing farm productivity resulting in a large yield gap. Extensive rain-fed agriculture (90% of all cropland) under unpredictable and erratic rainfall pattern is a leading cause of the low productivity and food insecurity in Africa, together with a low degree of mechanization. This has been reinforcing a persistent poverty trap, triggered by cyclical famines that are jeopardizing local development opportunities.
In a new IIASA-led study as part of the research project Renewables for African Agriculture (RE4AFAGRI), an international ...
Looking out for kids: a case for better pediatric trauma interventions
2023-08-23
In the weeks following the onset of the COVID-19 pandemic, public health directives called for masking, social distancing, social isolation, and stay-at-home orders. Apart from the severe medical consequences as a direct result of the pandemic, the ensuing social isolation had far-reaching impacts on children. The pandemic control measures affected the pediatric population by increasing mental distress, limiting physical activity, changing sleep patterns, and reducing emergency room visits. Unfortunately, the scope of pediatric trauma during the pandemic remains ...

Unravelling the water dynamics and structure of water-coordinated metal complexes
2023-08-23
Lanthanide-containing complexes are important compounds for sophisticated nuclear-fuel processing and medical imaging. Moreover, they often have interesting symmetric crystal structures and associated dynamics that render unique properties for practical applications.
The seven-coordinate lanthanide complex Ho(III) aqua-tris(dibenzoylmethane) or Ho-(DBM)3·H2O was first reported in the late 1960s. It has a three-fold symmetric structure with holmium (Ho) at the center of three propeller-shaped dibenzoylmethane (DBM) ligands and a water (H2O) ...
Artificial intelligence can now estimate rice yields, according to new study
2023-08-23
With the rise in global demand for staple crop products projected to substantially increase by 2050 due to population growth, rising per capita income, and the growing use of biofuels, it is necessary to adopt sustainable agricultural intensification practices in existing croplands to meet this demand. However, estimation processes currently employed in the global South remain inadequate. Traditional methods like self-reporting and crop cutting have their limitations, and remote sensing technologies are not fully utilized in this context.
However, recent advancements in artificial intelligence and machine learning, particularly deep learning with convolutional ...

Heart attack and stroke survivors neglect LDL cholesterol despite increased risk
2023-08-23
DALLAS, August 23, 2023 — A 2023 survey from the American Heart Association conducted by The Harris Poll, found that a majority (70%) of heart attack and stroke survivors are unaware that LDL cholesterol is commonly referred to as 'bad cholesterol.' This matters because LDL cholesterol (low-density lipoprotein cholesterol) significantly contributes to the development of cardiovascular disease, increasing the risk of heart attacks and strokes. According to the Centers for Disease Control and Prevention, ...
FAU lands $4.2 million NIH grant for air quality and Alzheimer’s risks study
2023-08-23
Worldwide, the practice of preparing agricultural fields by burning crop residue contributes large quantities of gaseous pollutants and aerosol particles to the atmosphere and is a known cardiorespiratory health hazard. It has been shown that combustion byproducts in smoke cross the blood-brain barrier causing brain inflammation, and repeated inhalation of smoke can contribute to cognitive decline and dementia among older adults.
Federal efforts to monitor air quality have been focused on population-dense urban communities. As such, impacts of smoke exposure from agricultural fires ...
Study connects neural gene expression differences to functional distinctions
2023-08-23
Figuring out how hundreds of different kinds of brain cells develop from their unique expression of thousands of genes promises to not only advance understanding of how the brain works in health, but also what goes wrong in disease. A new MIT study that precisely probes this “molecular logic” in two neuron types of the Drosophila fruit fly, shows that even similar cells push and pull many levers to develop distinct functions.
In the study in Neuron, a team of neurobiologists at The Picower Institute for Learning and ...
