Glioblastomas are the most common and most aggressive brain tumours. Their survival rate has barely increased over the last 50 years, indicating an urgent need to develop new therapeutic strategies.
For the first time, researchers have been able to obtain data from underneath Thwaites Glacier, also known as the "Doomsday Glacier". They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow.
With the help of the uncrewed submarine Ran that made its way under Thwaites glacier front, the researchers have made a number of new discoveries. Professor Karen Heywood of the University of East Anglia commented:
Active surveillance leads to improved quality of life
Men with low health literacy seven times less likely to accept active surveillance
Prostate cancer and active surveillance patient education is needed
Glass is ubiquitous, from high-tech products in the fields of optics, telecommunications, chemistry and medicine to everyday objects such as bottles and windows. However, shaping glass is mainly based on processes such as melting, grinding or etching. These processes are decades old, technologically demanding, energy-intensive and severely limited in terms of the shapes that can be realized. For the first time, a team led by Prof. Dr. Bastian E.
Researchers at Lund University in Sweden have discovered that bird blood produces more heat in winter, when it is colder, than in autumn. The study is published in The FASEB Journal.
The secret lies in the energy factories of cells, the mitochondria. Mammals have no mitochondria in their red blood cells, but birds do, and according to the research team from Lund and Glasgow this means that the blood can function as a central heating system when it is cold.
Michigan State University's Witold Nazarewicz has a simple way to describe the complex work he does at the Facility for Rare Isotope Beams (frib.msu.edu), or FRIB.
"I study theoretical nuclear physics," said Nazarewicz, John A. Hannah Distinguished Professor of Physics and chief scientist at FRIB. "Nuclear theorists want to know what makes the nucleus tick."
Led by a South African team at the South African Medical Research Council Centre for Health Economics and Decision Science (PRICELESS-SA) in the School of Public Health at the University of the Witwatersrand, Johannesburg (Wits), and the University of the Western Cape, in partnership with the University of North Carolina, USA, the study was published on 8 April in The Lancet Planetary Health.
There are millions of people who face the loss of their eyesight from degenerative eye diseases. The genetic disorder retinitis pigmentosa alone affects 1 in 4,000 people worldwide.
Today, there is technology available to offer partial eyesight to people with that syndrome. The Argus II, the world's first retinal prosthesis, reproduces some functions of a part of the eye essential to vision, to allow users to perceive movement and shapes.
Study: "How Do Weighted Funding Formulas Affect Charter School Enrollments?"
Author: Paul Bruno (University of Illinois at Urbana-Champaign)
This study was presented today at the American Educational Research Association's 2021 Virtual Annual Meeting.
Main Findings:
The adoption of a school funding system in California that increased revenues for schools enrolling higher-need students led to an increase in the rate at which charter schools enrolled low-income students.
Auroral displays continue to intrigue scientists, whether the bright lights shine over Earth or over another planet. The lights hold clues to the makeup of a planet's magnetic field and how that field operates.
New research about Jupiter proves that point -- and adds to the intrigue.
Peter Delamere, a professor of space physics at the University of Alaska Fairbanks Geophysical Institute, is among an international team of 13 researchers who have made a key discovery related to the aurora of our solar system's largest planet.
New York, NY (April 10, 2021) - A personalized cancer vaccine developed with the help of a Mount Sinai computational platform raised no safety concerns and showed potential benefit in patients with different cancers, including lung and bladder, that have a high risk of recurrence, according to results from an investigator-initiated phase I clinical trial presented during the virtual American Association for Cancer Research (AACR) Annual Meeting 2021, held April 10-15.
HOUSTON - Researchers at The University of Texas MD Anderson Cancer Center have discovered that mutant KRAS and p53, the most frequently mutated genes in pancreatic cancer, interact through the CREB1 protein to promote metastasis and tumor growth. Blocking CREB1 in preclinical models reversed these effects and reduced metastases, suggesting an important new therapeutic target for the deadly cancer.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have shown that a quantity known as "thermoelectric conductivity" is an effective measure for the dimensionality of newly developed thermoelectric nanomaterials. Studying films of semiconducting single-walled carbon nanotubes and atomically thin sheets of molybdenum sulfide and graphene, they found clear distinctions in how this number varies with conductivity, in agreement with theoretical predictions in 1D and 2D materials. Such a metric promises better design strategies for thermoelectric materials.
Ferroelectric materials are used in many devices, including memories, capacitors, actuators and sensors. These devices are commonly used in both consumer and industrial instruments, such as computers, medical ultrasound equipment and underwater sonars.
Over time, ferroelectric materials are subjected to repeated mechanical and electrical loading, leading to a progressive decrease in their functionality, ultimately resulting in failure. This process is referred to as 'ferroelectric fatigue'.
An international research team led by Monash University has uncovered a new technique that could speed up recovery from bone replacements by altering the shape and nucleus of individual stem cells.
The research collaboration involving Monash University, the Melbourne Centre for Nanofabrication, CSIRO, the Max Planck Institute for Medical Research and the Swiss Federal Institute of Technology in Lausanne, developed micropillar arrays using UV nanoimprint lithography that essentially 'trick' the cells to become bone.
