Glioblastoma is the most frequent and aggressive brain cancer due to its ability to escape the immune system. However, the way in which this tumor manages to induce this immune tolerance was not known in detail. A research published in PNAS carried out at the Instituto de Neurociencias UMH-CSIC, in Alicante (Spain), and the IMIB-Arrixaca in Murcia (Spain), has find out in detail how this tumor invade healthy tissue with hardly any resistance, a finding that could become glioblastoma´s Achilles heel.
FORT LAUDERDALE/DAVIE, Fla. - With the recent celebration of the 50th anniversary of the Apollo program's first landing of humans on the moon, the eyes and hopes of the world turn skyward again.
EVANSTON, Ill. -- Researchers have developed a tiny nanolaser that can function inside of living tissues without harming them.
Just 50 to 150 nanometers thick, the laser is about 1/1,000th the thickness of a single human hair. At this size, the laser can fit and function inside living tissues, with the potential to sense disease biomarkers or perhaps treat deep-brain neurological disorders, such as epilepsy.
A snapshot of health conditions revealing the disparities across 38 neighborhood areas in Harris County has been published in the 2018 Health of Houston Survey by The University of Texas Health Science Center at Houston (UTHealth) School of Public Health.
Phoenix, Arizona, USA: From the Great Pacific garbage patch to inland rivers, plastics are among the most widespread contaminants on Earth. Microplastics -- particles of plastic smaller than five millimeters -- are especially pervasive. As they build up in Earth's waters, microplastics are also becoming a permanent part of the planet's sedimentary layers.
Now, using the Great Lakes as a laboratory, sedimentary petrologist Patricia Corcoran and her students at the University of Western Ontario are studying the behavior of microplastics as a geologic phenomenon.
Phoenix, Arizona, USA: Over the past 30 years, wildfires have gotten bigger, stronger, and occurred more often. As climates continue to warm, this trend will likely continue, causing disruption to landscapes and water systems alike.
Wildfires are destructive to ecosystems, but they can also set the stage for future issues. "After a wildfire, particularly a high-severity wildfire, you have significant impacts to the soil that affects the infiltration of water," says Brendan Murphy, a research associate at Utah State University.
COLUMBUS, Ohio -Climate change and over-tapped waterways could leave developing parts of Asia without enough water to cool power plants in the near future, new research indicates.
The study found that existing and planned power plants that burn coal for energy could be vulnerable. The work was published today in the journal Energy and Environment Science.
In the body's cells, some proteins are of vital importance as to which genes are active or turned off. Now, researchers from the University of Copenhagen and the Memorial Sloan Kettering Cancer Center have discovered which proteins are necessary in order to maintain the proper genetic regulation.
All of the more than 200 different cell types in our body contain the same DNA. Which of those genes that are expressed determine each cell type. Therefore, it is essential that the activity of the genes is controlled with great precision.
A new study has discovered that US students achieve better results in reading and mathematics tests when they stay in elementary school for grades six (age 11-12) and seven (age 12-13), rather than transfer to middle school. In contrast, students in grade eight (age 13-14) achieve better results in middle school than high school.
RUDN University mathematician for the first time proved the theorem of existence and uniqueness of solutions of the Zakharov-Kuznetsov equation in a strip. Such theorems are very rare for partial differential equations. The new results can be applied, for instance, in astrophysics, in describing the propagation of plane waves in plasma. The article is published in the journal Nonlinear Analysis: Real World Applications.
Over millions of years, porpoises have developed powerful biosonar with high accuracy and intelligence to detect and track preys in underwater noisy environment. The sound source in a porpoise is about one half of the wavelength of its emitted acoustic waves. According to textbook sonar theories, it is difficult to control the directional sound waves for target detection. Porpoises, with remarkable sonar detection capabilities, have been known as natural legend of echolocation. How to reconstruct their acoustic super-structures is a huge challenge for artificial design.
A German and British research team lead by Technical University of Munich (TUM) has examined the interplay between genetics, cardiovascular disease and educational attainment in a major population study. Genetic variants which had been linked to educational attainment in other studies were observed in the subjects. The researchers found that these variants also had implications for a more health-conscious lifestyle and thus a lower risk of cardiovascular disease - in some cases regardless of the level of education.
A new report reveals the relationships between transport and property value across the North of England. The report highlights how understanding these relationships can help inform infrastructure planning and investment - from inter-city rail connections to shaping the urban environment.
Researchers from the Institute for Transport Studies at the University of Leeds have developed three new models of the property market in the North of England - an area of 40,000km2 with 15 million people and 7.1 million homes.
WEST LAFAYETTE, Ind. -- It may still be decades before quantum computers are ready to solve problems that today's classical computers aren't fast or efficient enough to solve, but the emerging "probabilistic computer" could bridge the gap between classical and quantum computing.
Engineers at Purdue University and Tohoku University in Japan have built the first hardware to demonstrate how the fundamental units of what would be a probabilistic computer - called p-bits - are capable of performing a calculation that quantum computers would usually be called upon to perform.
(Carlisle, Pa., Sept. 18, 2019) - New research published today in the journal Science Advances challenges the conventional view of how a vital and life-sustaining feature of weathered rock is created. Porosity, the void space found in rock, was traditionally thought to be formed as water flowed through, chemically dissolving minerals. Now, researchers have found physical weathering, such as tree root wedging or ice cracking, bear a larger responsibility for creating porosity than previously thought.
