Long-term data show hurricanes are getting stronger

Long-term data show hurricanes are getting stronger

In almost every region of the world where hurricanes form, their maximum sustained winds are getting stronger. That is according to a new study by scientists at the National Oceanic and Atmospheric Administration National Center for Environmental Information and University of Wisconsin–Madison Cooperative Institute for Meteorological Satellite Studies, who analyzed nearly 40 years of hurricane satellite imagery. A warming planet may be fueling the increase. “Through modeling and our understanding of atmospheric physics, the study agrees with what we would expect to see in a warming...

Research reveals gene role in both dementia and severe Covid-19

People with a genetic mutation that increases the risk of dementia also have a greater chance of having severe Covid-19, researchers have .The study is the latest to suggest in why some people are more vulnerable to the coronavirus than others, and could help explain why people with dementia have been hard hit: dementia is among those who have died from Covid-19 in England and Wales.“It is not just age: this is an example of a specific gene variant causing vulnerability in some people,” said David Melzer, a professor of epidemiology and public health at Exeter University and a co-author of...

The oldest disk galaxy yet found formed more than 12 billion years ago

May 20, 2020 at 11:09 amThe oldest disk-shaped galaxyever spotted formed just 1.5 billion years after the Big Bang, a new studyfinds.That’s much earlier than astronomers thought that this type of galaxy could form. Previous observations show that disk-shaped galaxies — including sprawling, spiral systems like the Milky Way — didn’t show up in large numbers until between 3 billion and 4 billion years after the Big Bang, which occurred about 13.8 billion years ago.This precocious galaxy’sexistence suggests that massive spiral galaxies like the Milky Way , astronomers report in the May 21...

IRF5 guides monocytes toward an inflammatory CD11c+ macrophage phenotype and promotes intestinal inflammation

IRF5 guides monocytes toward an inflammatory CD11c+ macrophage phenotype and promotes intestinal inflammation

Intestinal homeostasis relies on maintenance of a complex set of interactions between intestinal microbiota and the intestinal immune system. Pathogens that colonize the gut invariably disrupt these interactions and promote intestinal inflammation. Here, Corbin et al. have used a mouse pathobiont, Helicobacter hepaticus, that causes inflammation akin to human inflammatory bowel disease (IBD) to study the role of intestinal macrophages in driving inflammation. Using this model, they found the transcription factor IRF5 to be a critical regulator of macrophage inflammatory potential and that...

Solving the space junk problem

Solving the space junk problem

May 25, 2020by Kelsey Simpkins, University of Colorado at BoulderSpace is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it's an international agreement to charge operators "orbital-use fees" for every satellite put into orbit.Orbital use fees would also increase the long-run value of the space industry, said economist Matthew Burgess, a CIRES Fellow and co-author of the new...

Galactic crash may have triggered Solar System formation

/ / /The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.Astronomers have known that Sagittarius repeatedly smashes through the Milky Way’s disc, as its orbit around the galaxy’s core tightens as a result of gravitational forces. Previous studies suggested that Sagittarius, a so called dwarf galaxy, had had a profound effect on how stars move in the Milky Way.  that the 10 000 times more...

Filed under:There won’t be the usual crowds near the Kennedy Space CenterAhead of this week’s launch of SpaceX’s Crew Dragon spacecraft, NASA is working to keep the enduring threat of COVID-19 at bay during the historic launch. To protect its astronauts, ground crew, and potential visitors, NASA has adjusted their approach to this highly anticipated event. If successful, the launch will not only break the US’s nine-year drought of crewed launches to the ISS, but it will also make history as the first time a private spacecraft has carried people into orbit.“We’re taking extra precautions,”...

New research published in provides new insight into nostalgia for past sexual experiences. The study indicates people who shun intimacy and dislike depending upon their partner are less likely to “calibrate” their sexual nostalgia based on their current needs.“In general, I am interested in how people maintain sexual desire and satisfaction over time,” said study author , an assistant professor at York University and the York Research Chair in Relationships and Sexuality.“We know that high-quality romantic relationships are important for overall well-being and one of the aspects of...

An objective Bayesian analysis of life’s early start and our late arrival

An objective Bayesian analysis of life’s early start and our late arrival

Edited by Neta A. Bahcall, Princeton University, Princeton, NJ, and approved April 7, 2020 (received for review December 9, 2019)Does life’s early emergence mean that it would reappear quickly if we were to rerun Earth’s clock? If the timescale for intelligence evolution is very slow, then a quick start to life is actually necessary for our existence—and thus does not necessarily mean it is a generally quick process. Employing objective Bayesianism and a uniform-rate process assumption, we use just the chronology of life’s appearance in the fossil record, that of ourselves, and Earth’s...

Astronomers Just Found an Extremely Rare 'Ring of Fire' Galaxy in The Early Universe

Astronomers Just Found an Extremely Rare 'Ring of Fire' Galaxy in The Early Universe

In the early days of the Universe, 10.8 billion years ago, astronomers have just found a galaxy wearing the battlescars of a cosmic brawl. It's not a blob or disc of stars, like most galaxies, but a giant doughnut - with a huge hole punched right through its centre. This classifies it as a rare type of galaxy known as a ring galaxy, and it's rare even among that type - its shape forged not by internal processes, but a collision that saw its core stripped away as the other galaxy passed through.The galaxy is called R5519, and it's the first collisional ring galaxy ever found more than a few...

Social identity threat predicts the concealment of nonreligious identity, study finds

New research published in provides insight into what motivates some nonreligious individuals to conceal their lack of belief. The findings suggest that awareness of anti-atheist stigma is an important predictor of public identification as an atheist.“This work is based on my Master’s thesis. I had noticed throughout the initial research process that there was a growing number of articles about how people felt toward the nonreligious in America, but not that many articles talked about how the nonreligious felt about being disliked by a majority of Americans,” said study author Cameron...

Why Sex? Biologists Find New Explanations

Why Sex? Biologists Find New Explanations

Why did sex evolve? Theories usually focus on the diversity of future generations, but some researchers find compelling explanations in the immediate benefits to individuals.April 23, 2020Sex might be biology’s most difficult enigma. The downsides of relying on sex to reproduce are undeniable: It takes two individuals, each of whom gets to pass on only part of their genome. Because these individuals generally have to get fairly intimate, they make themselves vulnerable to physical harm or infections from their partner. Asexual reproduction, or self-cloning, has none of these disadvantages....
