Published Now, every biologist can use machine learning
(via sciencedaily.com) Original source Scientists have built a new, comprehensive AutoML platform designed for biologists with little to no ML experience. New automated machine learning platform enables easy, all-in-one analysis, design, and interpretation of biological sequences with minimal coding. Their platform, called BioAutoMATED, can use sequences of nucleic acids, peptides, or glycans as input data, and its performance is comparable to other AutoML platforms while requiring minimal user input.
Published DNA can fold into complex shapes to execute new functions
(via sciencedaily.com) Original source DNA can mimic protein functions by folding into elaborate, three-dimensional structures, according to a new study.
Published Researchers reveal mechanism of protection against breast and ovarian cancer
(via sciencedaily.com) Original source Researchers have outlined the structure and function of a protein complex which is required to repair damaged DNA and protect against cancer.
Published Detection of an echo emitted by our Galaxy's black hole 200 years ago
(via sciencedaily.com) Original source An international team of scientists has discovered that Sagittarius A* (Sgr A*), the supermassive black hole at the centre of the Milky Way, emerged from a long period of dormancy some 200 years ago. The team, led by Frédéric Marin, a CNRS researcher at the Astronomical Strasbourg Observatory (CNRS/University of Strasbourg), has revealed the past awakening of this gigantic object, which is four million times more massive than the Sun. Their work is published in Nature on 21 June.
Published Exoplanet may reveal secrets about the edge of habitability
(via sciencedaily.com) Original source How close can a rocky planet be to a star, and still sustain water and life? A recently discovered exoplanet may be key to solving that mystery.
Published Scientists discover new embryonic cell type that self-destructs to protect the developing embryo
(via sciencedaily.com) Original source Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Published The speed of life: A zoo of cells to study developmental time
(via sciencedaily.com) Original source Researchers have used an unprecedented stem cell zoo to compare six different mammalian species and their developmental time.
Published Jupiter's moon Europa may have had a slow evolution
(via sciencedaily.com) Original source Europa may have a metamorphic origin for the ocean. While some scientists speculated this, a research team shows that if Europa indeed formed from hydrated rocks (i.e., rocks have hydrogen and oxygen), then enough of Europa's interior should get hot enough to release water directly from the hydrated rocks to form the ocean and ice shell.
Published Researchers demystify the unusual origin of the Geminids meteor shower
(via sciencedaily.com) Original source Princeton researchers used observations from NASA's Parker Solar Probe mission to deduce that it was likely a violent, catastrophic event -- such as a high-speed collision with another body or a gaseous explosion -- that created the Geminids meteoroid stream. Mysteries surrounding the origin of the Geminids have long fascinated scientists because, while most meteor showers are created when a comet emits a tail of ice and dust, the Geminids stem from an asteroid -- a chunk of rock that normally does not produce a tail. Until now, this unusual meteoroid stream had only been studied from Earth.
Published Tethering of shattered chromosomal fragments paves way for new cancer therapies
(via sciencedaily.com) Original source Scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous mutations.
Published Close up on aging reveals how different cell types in the body age at different pace
(via sciencedaily.com) Original source A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
Published Scientists report 'benchmarks' for extreme space weather
(via sciencedaily.com) Original source Extreme space weather threatens vital satellites orbiting the Earth, including the Global Navigation Satellite Systems (GNSS) which pass through the heart of the outer radiation belt. New research has now determined a series of benchmarks for the likely severity of extreme space weather events in GPS orbit.
Published Earth was created much faster than we thought: This makes the chance of finding other habitable planets in the Universe more likely
(via sciencedaily.com) Original source Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that water and other essential ingredients for life were delivered to Earth very early on.
Published A scorching-hot exoplanet scrutinized by astronomers
(via sciencedaily.com) Original source Through the Gemini-North Telescope in Hawai'i, the chemical composition of WASP-76 b is revealed in unprecedented detail, giving new insights also into the composition of giant planets.
Published Plate tectonics not required for the emergence of life
(via sciencedaily.com) Original source New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that harbor life, the planets do not necessarily need to have plate tectonics,' says the lead author of a new paper.
Published Sun's coldest region stores secret to heating million-degree corona
(via sciencedaily.com) Original source Researchers have unveiled the discovery of intense wave energy from a relatively cool, dark and strongly magnetized plasma region on the Sun, capable of traversing the solar atmosphere and maintaining temperatures of a million degrees Kelvin inside the corona. Researchers say the finding is the latest key to unraveling a host of related mysteries pertaining to Earth's nearest star.
Published Scientists discover small RNA that regulates bacterial infection
(via sciencedaily.com) Original source Researchers have identified the major mechanism behind the transition between chronic and acute P. aeruginosa infections. Their research findings can inform the development of future treatments for life-threatening acute infections.
Published Key building block for life found at Saturn's moon Enceladus
(via sciencedaily.com) Original source The search for extraterrestrial life in our solar system just got more exciting. A team of scientists has discovered new evidence that the subsurface ocean of Saturn's moon Enceladus contains a key building block for life. The team directly detected phosphorus in the form of phosphates originating from the moon's ice-covered global ocean using data from NASA's Cassini mission. Cassini explored Saturn and its system of rings and moons for over 13 years.
Published First illustration of the molecular machinery that makes cilia beat
(via sciencedaily.com) Original source The first image of the structures that power human cilia -- the tiny, hairlike projections that line our airways -- has now been produced and it could lead to much-needed treatments for people with rare cilial diseases.
Published Pass the salt: This space rock holds clues as to how Earth got its water
(via sciencedaily.com) Original source The discovery of tiny salt grains in a sample from an asteroid provides strong evidence that liquid water may be more common in the solar system than previously thought.
