Human immune cells are capable of coordinating their own movement more independently than previously thought. InFLAMES researcher Jonna Alanko has discovered that immune cells do not just passively follow the chemical cues in their environment. Quite the contrary, they can also shape these cues and navigate in complex environments in…
The artist in nature creates wonders of geometric patterns, as can be seen in the wings of Drosophila fruit flies just after emerging from their pupal case, which is known as eclosion. They meticulously fold into stereotypic shapes, just like in the paper-folding art of origami, invented from humanity’s innate…
An international study led by the Coma Science Group of the University of Liège (BE) and involving more than ten institutions has tested transcranial direct current stimulation (tDCS) on a large number of patients suffering from consciousness disorders following severe brain injury. These results represent a significant advance in how…
Mold and diseases caused by fungi can greatly impact the shelf life of fruit and vegetables. However, some fungi benefit their hosts by aiding plant survival. Colletotrichum tofieldiae (Ct) is a root mold which typically supports continued plant development even when the plant is starved of phosphorus, an important nutrient…
Salk scientists identified new set of molecules that drive the growth of human pancreatic cancer cell lines, explaining how genetic mutations can activate genetic “super-enhancers” that promote out-of-control pancreatic cancer growth. They show the efficacy of an experimental drug that targets a super-enhancer related protein, demonstrating the promise of therapeutics…
Scientists have achieved a breakthrough in the development of non-volatile phase change memory−−a type of electronic memory that can store data even when the power is turned off−−in a material that has never displayed the sort of characteristics that such memory requires. Until now, phase change memory has primarily been…
Farmers usually plant so-called cover crops after harvesting their main crop in the Fall. This prevents erosion of the soil and nutrient leaching. The roots of these crops also stabilize the structure of the soil. It had been assumed up to now that a mixture of different cover crops would…
As drinking water flows through pipes and into a glass, it runs against the rubber seals inside some plumbing devices. These parts contain additives that contribute to their flexibility and durability, but these potentially harmful compounds can leak into drinking water, according to a small-scale study in ACS’ Environmental Science…
To reimagine existing preclinical trials for Alzheimer’s disease, University of Pittsburgh School of Medicine neuroscientists created the first non-human primate model of hereditary Alzheimer’s in marmoset monkeys, outlining their approach in Alzheimer’s & Dementia: Translational Research & Clinical Interventions. Researchers are now working on characterizing and validating genetic, molecular, functional…
The liver produces bile, which the intestine uses for digestion. For the transport of bile, the liver relies on a network of microscopic tubings, known as bile canaliculi, formed by liver cells called hepatocytes. When the outflow of bile to the intestine is blocked, it collects in the liver and…
Pumping liquids may seem like a solved problem but optimizing the process is still an area of active research. Any pumping application — from industrial scales to heating systems at home — would benefit from a reduction in energy demands. Researchers at the Institute of Science and Technology Austria (ISTA)…
Although about half of people go through menopause, less than 15% of them receive effective treatment for their symptoms. Treatment options for people experiencing irritating or severe menopause symptoms are often under researched, and some have questionable efficacy, or cause harmful side effects. In a comprehensive review publishing in the…
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides…
CNN — Ukrainian officials continue to sound optimistic that the second line of Russian defensive fortifications on the southern front may be easier to penetrate than the first, as Kyiv’s troops try to push through a web of dense minefields in a grinding counteroffensive. Geolocated video in recent days indicates…
CNN — Public schools in France have been turning away students for breaking a new national ban on the abaya, a long, robe-like garment often worn by Muslim women, as a rights group filed an appeal against the prohibition. A total of 67 girls returned home rather than remove their…
CNN — The United Kingdom is set to classify Russia’s Wagner mercenary group as a terrorist organization, a move that will open the door to prosecution of its members and supporters. The decision – which puts the the organization into the same category as the likes of al Qaeda, ISIS…
