Another difference between matter and antimatter has been found

 Finding the difference between matter and antimatter may be a bit like the scientific equivalent of playing “find 10 differences between pictures”. There is a lot at stake in this task: it is the answer to the question of why we exist. Now, in the LHCb experiment at CERN, the researchers have found another (though not yet the last) difference.


Shortly after the Big Bang — as it can be assumed — equal numbers of particles of matter and antimatter should be formed. The particle has the opposite charge and is a mirror image of its antiparticle. And when these two meet — it is annihilated. It would seem that all particles and antiparticles should immediately turn into energy in the processes of annihilation. But it didn’t, because we, the Universe, and the rest do exist. And we are made of matter. Antimatter is much rarer.

Mesons are unstable particles — but live long enough for their properties to be studied. The first mesons (pions) were observed in the first half of the 20th century in cosmic rays. Today we know that they are composed of a pair of a quark and an antiquark, and since there are 6 types of quarks themselves (physicists talk about six smells, which has absolutely nothing to do with the olfactory sensations of everyday life!), The combinations leading to different mesons really are many. Of course, each meson also has its own antiparticle, in which the respective quarks and antiquarks are turned into their antiparticles.

The breaking of CP symmetry in the decays of neutral kaons, i.e. mesons with a quark and an upper and a strange antiquark, was observed over half a century ago and was awarded the Nobel Prize. Twenty years ago, symmetry breaking was also noticed among mesons containing a beautiful quark. The mystery was, among others, the mesons with the charm quark, which in terms of mass is between the strange and the beautiful quark.

- Until now, we have not been able to measure directly and with the appropriate precision how the breaking of CP symmetry manifests itself in the decays of charm mesons. The results of the analyzes presented at the recently completed ICHEP conference of high energy physics in Bologna perfectly fill this gap — says Prof. Wojciech Wiślicki from the National Center for Nuclear Research (NCBJ), quoted in a statement from his institute. The results are available on the LHCb website.

The latest results are the result of detailed analyzes of about fifty million cases with the decay of D0 charm mesons into positively and negatively charged kaons. These decays were recorded over several years during proton collisions in the LHCb detector operating at the Large Hadron Collider at the CERN facility near Geneva. Part of the calculations related to data processing were carried out in the Świerk IT Center.

- In fact, breaking the space-charge symmetry in the decays of charm mesons was first noticed in the LHCb experiment three years ago — explains Dr. Artur Ukleja (NCBJ) in a release. — Contrary to the current measurement, however, the contemporary one did not suggest so clearly possible different matter-antimatter asymmetries between the decays of charm mesons into kaon-anti-kaon pairs and decays into pawn-antimatter pairs — he adds.

Physicists comment that the latest results from the LHCb detector experiments provide a key complement to our understanding of the difference between matter and antimatter. The Standard Model imposes restrictions on breaking the symmetry between matter and antimatter. If too many such phenomena were observed, the result would be inconsistent with the predictions of the Standard Model, signaling the existence of a new physics.

- The data presented in Bologna show that breaking the CP symmetry is rare in the case of charm mesons — concludes Prof. Wiślicki. Rarely enough that these results do not contradict the Standard Model describing elementary particles and their interactions.

However, physicists explain that the discrepancy between the amount of matter observed in the universe and the predictions of our cosmological models remains visible even after taking into account the latest results. So it is not yet the last difference between matter and antimatter. However, the mystery still does not have a complete answer. “More clues to unravel this mystery may be seen in the next stage of particle collisions in the LHC accelerator that has just begun,” physicists hope.

Charitable Writing: How to Become a Career Grant Writer

 

What Is a Grant Writer?

When you hear the term “grant writer”, you likely think of someone who writes grants. This is not quite true. Grant writers don’t write grants; They write grant proposals.

Grant proposals are research documents that companies and non-profit organizations send to grant donors in an effort to secure funding. The purpose of the proposal is to convince the donor that the organization’s project is worth supporting. As such, the proposal needs to be impeccably written.

Because many organizations lack the skill or wherewithal needed to write a good grant proposal, they sometimes export the task to a professional, someone who understands how grants work and how to secure them. This professional is, of course, the grant writer.

Now, this isn’t to say that all grant writers work for themselves. Some organizations do employ grant writers full-time. However, the good majority of grant writers work as freelancers, offering their services to numerous companies, schools, non-profits, and other such organizations.

Responsibilities of a Grant Writer

While they’re known as grant writers, their responsibilities include more than just writing. The primary responsibilities of a grant writer will be reviewed below.

Research Available Grants

One of the biggest responsibilities of a grant writer is to research grant funding opportunities. This is done to ascertain which grants would best suit his or her clients’ projects.

See, grants are typically not generalized. In most cases, they’re designed to cater to a specific sector or industry. For instance, an organization might create a grant to give to a company working in the healthcare industry.

As the grant writer, you need to choose a grant which aligns with your clients’ work. If you choose a grant which doesn’t align with the work of your client, your client’s organization will have no chance of winning it.

Write Proposals

As we’ve noted, grant writers write grant proposals. Grant proposals are meant to follow the guidelines of grant donors. Because of this, every proposal that’s written ends up being a little different from the last.

When writing, you not only need to be able to follow the provided guidelines, but you also need to be able to communicate factual information in a clear and inspiring manner. At its core, grant writing is persuasive writing.

Communicate With Clients and Donors

In order for a grant writer to secure grant funding, he or she must keep close communication with his or her clients as well as with prospective grant donors. Depending on the circumstances, this communication could happen either in-person, on the phone, or via email.

How to Become a Grant Writer

Now that you understand the responsibilities of a grant writer, you might be wondering how to become one. We’re going to get into the specifics below.

Brush Up on Your Writing Skills

The first step is to brush up on your writing skills. Not only must you possess impeccable grammar, but you must also be able to demonstrate a sophisticated vocabulary.

Look at a few examples of grant proposals as guidelines. Study the writing style contained within them and try your best to adopt it.

Take a Grant Writing Course

If you’re entirely new to the grant writing process, you would be wise to take a grant writing course. A grant writing course will not only help you with the writing of grant proposals but with client communication, research, and a variety of other skills.

Find a First Gig

Once you think you’re ready to write a grant proposal, you need to find your first gig. This can be challenging, as it requires you to put in a good deal of leg work. However, if you put the time in, you’ll almost certainly find an organization willing to give you a chance.

Starting out, your best bet is to call up or email non-profit organizations. Non-profits generally don’t have grant writers of their own, and generally don’t have a lot of money to pay one. Offer your services at a low rate (or for free), and you’re bound to snag your first gig.

Market Yourself

Once you’ve completed your first gig, you’ll have a better chance at landing other gigs. This is particularly true if your first gig was successful (ie. your client received a grant).

That being said, if you want to land consistent work, you need to market yourself properly. Create a website for your grant writing services, establish appropriate social media pages, and continue to reach out to organizations that might need proposals.

Skills Needed as a Grant Writer

Grant writers require a few different skills, all of which are fairly straightforward. First and foremost, grant writers must be able to write. If your grammar or vocabulary is poor, you’re going to have a difficult time securing a grant.

Secondly, you need to have solid research skills. Not only must you do research for your grant proposals, but you must also do research to discover available grants.

Lastly, you need to be able to communicate, both orally and in the written word. This is not a career for shy or complacent individuals. You will have to speak with clients and donors on a regular basis.

How Much Money Do Grant Writers Make?

Grant writers make varying amounts of money based on a number of different factors. These factors include success rate, number of clients, type of clients, monetary rate, and manner of work, to name just a few.

Entry-level grant writers generally charge between $30 and $40 an hour. However, experienced grant writers who work in big markets can charge as much as $100 an hour. If you have an especially high success rate, you can charge ever more than $100 an hour.

3 Creative Ways to Get Writing Inspiration

 


Poet Edith Sitwell would lie in an open coffin before beginning her writing every day. We often find our writing inspiration in the most unlikely places.

Every writer, no matter how great, needs inspiration, and you can’t just sit around waiting for it. It’s an indispensable part of the writing process, and you need to find what works for you.

Read on to to get some ideas on where to find your inspiration.

1. Read Regularly and With Intention

This may seem obvious, but all great writers need to read. But it’s not enough to “just read.” To get the most out of your reading, read with intention, and take the time to analyze the writing. Pay attention to how the writer writes, the grammar, how they develop their characters, and even their grammar and punctuation.

If you’re writing a book, take the time to observe the cover to get book cover design inspirations for your own novel. Read the author’s biography, or delve into at any artwork that might be in the book, whether it’s photography or anime drawings.

Read what you love, but also try reading outside of your comfort zone. If you’re a fiction reader, try reading some non-fiction or a comic book for a change. It’s when you try new things and experience something different that you’ll often get your best ideas.

2. Allow Time to Explore Non-Work Creative Outlets

Just like all parts of our body, our creative minds and imaginations need to be exercised. Often, the best writing inspiration comes from letting ourselves be free to create beyond our regular work.

Whatever helps you daydream and tap into your unconscious, do it. For many writers, writing in a daily journal or journaling about their dreams when they wake up is a fantastic outlet.

Providing your mind with sustenance doesn’t have to come in the form of writing. You can try other creative endeavors like painting, cooking, working with textiles, or doodling. Anything that gets your brain turning is the perfect activity to give your imagination a boost.

3. Try Eavesdropping

Numerous great writers have gained their best ideas from sitting around and listening to strangers.

So the next time you’re sitting on a train, sipping on a latte in your local coffee shop, or sitting on a park bench, do a little eavesdropping. You’ll get a look into other people’s lives, hear about the challenges they’re facing w, and discover new points of view.

Listening to other people’s conversations can also help writers with developing dialogue that sounds realistic and raw.

If eavesdropping makes you uncomfortable, just be conscious of respecting people’s boundaries. When a couple starts speaking in hushed voices, take that as a cue that they’re talking about something personal in nature and don’t want to be overheard. Respect that.

Marine conservation effort in US Virgin Islands aids key fish species, Oregon State research finds.

 


CORVALLIS, Ore. — A more than 30-year marine conservation effort in the U.S. Virgin Islands helped aid the recovery of a fish species important in commercial, recreational and subsistence fisheries, a new Oregon State University study found.

Red hind, a species of grouper in the Caribbean, historically experienced intense fishing pressure, which led managers to implement progressively restrictive fishing closures in the U.S. Virgin Islands.

In a study just published in Frontiers in Marine Science, researchers at Oregon State and the University of the Virgin Islands found that the fishing restrictions at the location they studied helped lead to a more than 35% increase in average fish size and the recovery of the population to a benchmark considered sustainable for many fish species.

“This is a management and conservation success,” said Claire Rosemond, an Oregon State doctoral student and lead author of the study. “The recovery of the red hind population at the spawning aggregation tracks management decisions, so it appears that fishing restrictions are helping to accomplish the intended goal of recovering the red hind population and fishery.”

Globally, more than 200 species of marine fishes, including red hind, reproduce by forming spawning aggregations at specific times and locations. The predictability of these mass spawning events makes the aggregations susceptible to intense fishing pressure.

Locations of many fish spawning aggregations in the Caribbean have been known and fished for decades. This has led to population collapse of several important species, including red hind, which are an important source of income and food for local people.

By the late 1980s, the red hind population at a spawning site near St. Thomas, U.S. Virgin Islands showed signs of decline with a decrease in average fish length and an extremely skewed ratio of females to males because fishing disproportionately removed the larger males.

This led fisheries managers in 1990 to establish the Red Hind Bank Marine Conservation District to protect the fish spawning site by seasonally closing the area to fishing during the months of peak spawning activity (December through February). In 1999, the district was permanently closed to fishing.

The just-published research focused on that spawning site. The scientists used historical data collected by other researchers between 1988 and 2009 and gathered their own data during several trips to the U.S. Virgin Islands between 2018 and 2020.

During those trips the resarchers caught, measured, and released 1,203 red hind. The mean size of the fish they caught was almost 16 inches, more than four inches longer than the mean size reported from data from 1988–89. Meanwhile, the female to male ratio at the spawning aggregation became less skewed over time.

By a measure known as spawning potential ratio, the red hind are now at a benchmark considered sustainable for many fisheries, the researchers note, but that does not mean that continued recovery is guaranteed.

“To me the take home message is this management measure worked, but it also means this management measure is currently working, so at this point in time let’s keep it the way it is,” said Scott Heppell, a co-author of the paper who is a professor in the Department of Fisheries, Wildlife, and Conservation Sciences at Oregon State in Oregon State’s College of Agricultural Sciences.

The recovery of the red hind population at the spawning aggregation site is due in part to management decisions, fishers adhering to closures and long-term monitoring.

“The Marine Conservation District is a conservation success due to the participation of people from many different sectors,” Rosemond said. “I think management agencies and fishers would be excited to know that their work and potential sacrifices, like not fishing in closed areas, have paid off.”

Richard Nemeth of the University of the Virgin Islands is also a co-author of this paper.

The National Oceanic and Atmospheric Administration, the Puerto Rico Sea Grant College Program, and the Department of Fisheries, Wildlife, and Conservation Sciences funded this research.

The James Webb Space Telescope has spotted the oldest galaxy ever seen

 After the publication of the first official full-size images and spectroscopic data from the James Webb Space Telescope, more and more new images from a state-of-the-art space observatory are emerging. Among them are observations of what could be the farthest observed galaxy. Researchers believe that the light of the galaxy GLASS-z13 dates back to a time when the universe was only 300 million years old.

An analysis of the latest data collected by the James Webb Space Telescope (JWST) has revealed a galaxy that dates back just 300 million years after the Big Bang. This is the oldest galaxy we have ever seen. The previous oldest identified galaxy found by the Hubble Space Telescope is called GN-z11 and dates back 400 million years after the birth of the universe.

The discovery article has been submitted to The Astrophysical Journal Letters and is awaiting review. It is currently available in the arXiv preprint database (arXiv: 2207.09434v1).

Galaxy GLASS-z13
The galaxy GLASS-z13 was discovered next to another very distant galaxy, GLASS-z11, whose light dates back 420 million years after the Big Bang. Together with the former farthest galaxy record holder GN-z11 and another contender called HD1, the objects suggest that there may be a population of very bright ancient galaxies that formed many stars very quickly.

These findings will still have to be confirmed. “We are potentially looking at the farthest starlight anyone has ever seen,” said Rohan Naidu of the Harvard Center for Astrophysics. And the more distant objects are from us, the longer it takes for their light to reach us, and therefore looking back into the distant universe is a look into the deep past.

The light from GLASS-z13 took 13.4 billion years to reach us, but the distance between us is now 33 billion light years due to the expansion of the universe. And although the galaxy GLASS-z13 existed in the earliest era of the universe, its exact age remains unknown. It could have formed at any point in the first 300 million years after the Big Bang.

Scientists managed to identify some of the object’s properties. According to them, GLASS-z13 has a mass of one billion Suns. Considering how quickly the galaxy formed after the Big Bang, this is quite surprising. “It’s something we don’t really understand,” admitted Naidu.

Promises of great discoveries

The galaxy was captured by near-infrared imaging devices called NIRcam (Near Infrared Camera). The ancient galaxy in the images looks like a blot of red with white in the center, and is part of a larger image of the distant cosmos known as Webb’s First Deep Field. This photo was shown to a wide audience by US President Joe Biden the day before the official publication of the first package of photos and spectroscopic data (more on this in the text: The US President showed the first deep space image made by JWST).

“Astronomical records are already crumbling and more are uncertain,” NASA’s Thomas Zurbuchen tweeted. “I only cheer when the scientific results are clear, peer-reviewed. But these discoveries look very promising, ‘he added.

Naidu and his colleagues worked on the image — a team of 25 astronomers from all over the world. The researchers acknowledged that another team of astronomers led by Marco Castellano who worked on the same data came to similar conclusions.

One of the great promises of the JWST is that it will be able to spot the earliest galaxies that formed after the Big Bang, 13.8 billion years ago. Because they are so distant from Earth, before the light emitted by them reached us, it was stretched by the expansion of the Universe and shifted into the infrared region of the light spectrum, which Webb detects with unprecedented sensitivity.

The team of researchers intends to ask Webb’s managers to use the equipment to perform spectroscopy — an analysis of light that reveals its detailed properties — to measure the exact distance to GLASS-z13, but working time with JWST will be difficult. As part of the observation campaign launched by the official presentation of the first photos, the Space Telescope Science Institute, which manages the observatory, has already allocated about 6,000 hours of observing time.

Russia is withdrawing from the International Space Station. He intends to build his own orbital station.

 

The recently appointed new head of Roscosmos, Yuri Borisov, announced that Russia has decided to abandon its participation in the International Space Station (ISS) project after 2024. As he announced, Moscow currently intends to focus on building its own orbital station.

This is the end of the International Space Station as we know it. The new head of Roscosmos, Yuri Borisov, has confirmed that Russia will no longer be part of the ISS after 2024. He also added that Russia is giving up the project in order to focus on building its own orbital station.

Russia is leaving the ISS
- Of course, we will fulfill all obligations towards our partners, but the decision to withdraw from this station after 2024 has been made — said Borisov during a meeting with Russian President Vladimir Putin. “I think we’ll start building our own Russian orbital station by then,” he added, calling it the main priority of the national space program.

At the beginning of this year, the ISS mission was extended until 2030. However, Russia had previously considered withdrawing from the project. The former head of Roscosmos, Dmitry Rogozin, known for his controversial statements, has spoken about it many times. Like Russia’s unprovoked attack on Ukraine and subsequent sanctions imposed on that country by many countries involved in the ISS, led to tensions between Roscosmos and other project partners, which, it turns out, accelerated Russia’s decision.

Experts said Russia’s departure from the International Space Station will affect the country’s space sector and will deal a serious blow to the manned flight program. Moscow does not have much to blackmail partners participating in the ISS project. Until recently, Russian Soyuz rockets were the only way to reach orbit until Elon Musk’s SpaceX began making its flights in 2020.

What will happen to the station?
The entire structure is aging and without major refurbishment, the long-term future of the station is in question. Another issue that needs to be resolved is how the station will be kept in the correct orbit, and Roscosmos is responsible for this.

Roscosmos and NASA have agreed to continue to provide flights to US astronauts and Russian cosmonauts aboard their launch rockets — Soyuz and SpaceX Crew Dragon.

“This is unfortunate given the critical scientific work being done at the ISS and the valuable professional collaboration of our space agencies over the years,” said US State Department spokesman Ned Price. In turn, NASA administrator Bill Nelson admitted that the agency “was not informed about the decisions of any of the partners.”

What is Russia going to build?
Russia is heavily dependent on imports of everything from manufacturing equipment to consumer goods, and the effects of Western sanctions are expected to wreak havoc on the country’s economy in the long run. According to specialists, the construction of a modern orbital station cannot be successful in a country covered by sanctions. Even if Russia builds an orbital station, it will be a return to the 1980s.

Space analyst Vitaly Yegorov admitted that it is almost impossible to build a new orbital station from scratch in a few years. — Neither in 2024, nor in 2025, nor in 2026 will there be a Russian orbital station, said Yegorov AFP. He added that creating a fully-fledged space station would take at least a decade and would require “the most generous funding”. He also admitted that Russia’s departure from the ISS meant that Moscow would have to suspend its manned flight program “for several years” or even “indefinitely”.

ISS
The International Space Station is the largest and most complex international construction project in space. Its story began in 1998 in the steppes of Kazakhstan. It was from the cosmodrome there, at the top of the Proton rocket, that the first element of the future station was launched — the Russian Zarja module.

Currently, the ISS is the only fully functioning laboratory in space to conduct experiments and research in a weightless condition.

The ISS has experienced several potentially dangerous incidents recently. In July last year, the pressure dropped in the Zwiezda service module, which provides accommodation for crew members and operates the station’s life support systems. A month later, microcracks were detected in the Zarja module, which resulted in a slow but continuous leak of air. Experts indicate that the ISS is starting to show its age and that after 2025 there may be an “avalanche” of events related to broken equipment.

The facility, roughly the length of a soccer field, is divided into two main areas, one of which is controlled by Russia and the other by the United States and other nations. At present, it is not yet known what will need to be changed on the Russian side of the complex for the space station to function safely after Moscow’s departure.
