When the Universe was only a tenth of its current age its galaxies experienced a growth spurt. It was this period that the scientists in the ALPINE project (1) focused on when they used ESO's ALMA (2) telescope to carry out the first ever large survey of distant galaxies. To their surprise, these galaxies observed in the early stages of their life were far more mature than expected. Their work is the subject of a series of articles published on 27 October 2020 in the journal Astronomy & Astrophysics, signed among others by members of the CNRS and Aix-Marseille Université (3).
New possibilities for future developments in electronic and optical devices have been unlocked by recent advancements in two-dimensional (2D) materials, according to Penn State researchers.
Fossils recovered from Antarctica in the 1980s represent the oldest giant members of an extinct group of birds that patrolled the southern oceans with wingspans of up to 21 feet that would dwarf the 11½-foot wingspan of today's largest bird, the wandering albatross.
COMMON MUTATION IN PARKINSON'S DISEASE INCREASES CELL CALCIUM, MAY CAUSE BRAIN CELL DEATH

Johns Hopkins Medicine researchers have mapped out the cellular pathway that connects the most common genetic mutation associated with Parkinson's disease to brain cell death. In a new study, they show that the mutation initiates a biological pathway that could target brain cells most susceptible to the patterns of cell death leading to Parkinson's disease symptoms.
Ithaca, NY--A new study from the Cornell Lab of Ornithology confirms that most birds--but not all--synchronize their migratory movements with seasonal changes in vegetation greenness. This is the first study of its kind to cover the Western Hemisphere during the year-long life cycle of North American migratory birds that feed on vegetation, seeds, nectar, insects, or meat. The findings were published today in the Journal of Animal Ecology.
Research at Washington State University sheds new light on one molecule that may be used to treat a heart condition that can lead to stroke, heart attack and other forms of heart disease.
That molecule is mavacamten. Scientists at WSU's Integrative Physiology and Neuroscience department discovered it suppresses excessive force generated by hyper-contractile muscle cells in the human heart.
Genetic factors that reduce the placenta's capacity to protect the fetus from the zika virus are described by Brazilian researchers in an article published in PLOS Neglected Tropical Diseases. According to the authors, the findings help explain why only some babies whose mothers are infected by zika virus during pregnancy are born with some kind of anomaly.
Boulder, Colo., USA: Across the western U.S., severe wildfires fueled by tinder-dry vegetation have already burned more than 3.2 million hectares (8 million acres [as of the time of this press release]) -- an area the size of Maryland -- in 2020, and nearly six times that area burned this year in Australia. And even though neither country's worst-ever fire year is not yet over, concerns are already mounting regarding the next hazard these regions will face: dangerous and destructive debris flows.
Researchers at UPF, the National Centre for Cardiovascular Research, ICREA and Ciberned have identified a physiological mechanism that maintains the regenerative capacity of muscle stem cells, and surprisingly resists the passage of time far more than expected, until geriatric age. This study presents the results of more than seven years of research and collaborations with several laboratories in Europe and the US.
FOLSOM, Calif., October 27, 2020 - A new study published in the Journal of the American College of Cardiology found that regular consumption of foods rich in omega-3 eicosapentaenoic acid (EPA), found in marine foods like fatty fish, and alpha-linolenic acid (ALA), found in plant foods like walnuts, was associated with improved outcomes in individuals who suffered a heart attack, including decreased risk of death.
