Published How targeted nutrients can fight cancer



An international research team has discovered a new way to effectively treat cancer, by using nutrients to reactivate suppressed metabolic pathways in cancer cells.
Published The world's oldest wine discovered



A white wine over 2,000 years old, of Andalusian origin, is the oldest wine ever discovered.
Published Where to put head and tail?



Formation of the body axes is a critical part of embryonic development. They guarantee that all body parts end up where they belong and that no ears grow on our backs. The head-tail axis, for example, determines the orientation of the two ends of the body. It was previously assumed that this axis is largely determined by the interplay between the Nodal and BMP signals. However, there appears to be another player in this system, as researchers have now discovered by using an embryo-like model system they developed. In the absence of BMP, the signalling molecule beta-catenin takes on the role of the Nodal antagonist. This new mechanism could be a flexible solution for axis formation in embryos with different shapes.
Published Astronomers see a massive black hole awaken in real time



In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory's Very Large Telescope (ESO's VLT), to track how the galaxy's brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy -- likely the result of the sudden awakening of the massive black hole at its core.
Published How the ketogenic diet improves healthspan and memory in aging mice



The ketogenic diet has its fanatics and detractors among dieters, but either way, the diet has a scientifically documented impact on memory in mice. While uncovering how the high fat, low carbohydrate diet boosts memory in older mice, scientists identified a new molecular signaling pathway that improves synapse function and helps explain the diet's benefit on brain health and aging.
Published A high-fat diet may fuel anxiety



New research shows when animals are fed a diet high in saturated fat for nine weeks, their gut bacteria change in ways that influence brain chemicals and fuel anxiety.
Published Satellites to monitor marine debris from space



Detecting marine debris from space is now a reality, according to a new study. Until now, the amount of litter -- mostly plastic -- on the sea surface was rarely high enough to generate a detectable signal from space. However, using supercomputers and advanced search algorithms, the research team has demonstrated that satellites are an effective tool for estimating the amount of litter in the sea.
Published Wear it, then recycle: Designers make dissolvable textiles from gelatin



Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Published Previously uncharacterized parasite uncovered in fish worldwide



Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.
Published Pair of merging quasars at cosmic dawn



Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the Universe's earliest formation.
Published Research into structures of ape hearts provide insight into human evolution



Researchers have discovered new insights into the human heart's structure, revealing its evolutionary history. This study enhances understanding of heart development and its implications for treating heart disease.
Published Investigating the origins of the crab nebula



A team of scientists used NASA's James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.
Published When bacteria are buckling



Filamentous cyanobacteria buckle at a certain length when they encounter an obstacle. The results provide an important basis for the use of cyanobacteria in modern biotechnology.
Published High-precision measurements challenge our understanding of Cepheids



Scientists have clocked the speed of Cepheid stars -- 'standard candles' that help us measure the size of the universe -- with unprecedented precision, offering exciting new insights about them.
Published Vitamin B6: New compound delays degradation



A low vitamin B6 level has negative effects on brain performance. A research team has now found a way to delay the degradation of the vitamin.
Published The genetic 'switches' of bone growth



In mammals, only 3% of the genome consists of coding genes which, when transcribed into proteins, ensure the biological functions of the organism and the in-utero development of future individuals. But genes do not function alone. They are controlled by other sequences in the genome, called enhancers, which, like switches, activate or deactivate them as required. A team has now identified and located 2700 enhancers -- among millions of non-coding genetic sequences -- that precisely regulate the genes responsible for bone growth. This discovery sheds light on one of the major factors influencing the size of individuals in adulthood, and explains why their failure could be the cause of certain bone malformations.
Published Study on architecture of heart offers new understanding of human evolution



An international research team has uncovered a new insight into human evolution by comparing humans' hearts with those of other great apes.
Published Fasting primes the immune system's natural killer cells to better fight cancer, new study in mice finds



A team of researchers has shown for the first time that fasting can reprogram the metabolism of natural killer cells, helping them to survive in the harsh environment in and around tumors, while also improving their cancer-fighting ability.
Published Infectious H5N1 influenza virus in raw milk rapidly declines with heat treatment



The amount of infectious H5N1 influenza viruses in raw milk rapidly declined with heat treatment in laboratory research. However, small, detectable amounts of infectious virus remained in raw milk samples with high virus levels when treated at 72 degrees Celsius (161.6 degrees Fahrenheit) for 15 seconds -- one of the standard pasteurization methods used by the dairy industry. The authors of the study stress, however, that their findings reflect experimental conditions in a laboratory setting and are not identical to large-scale industrial pasteurization processes for raw milk.
Published Pair plasmas found in deep space can now be generated in the lab



Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported.
