Two new preliminary studies on recreational marijuana and health reinforce existing evidence that regular use has a negative impact on heart and brain health, according to the American Heart Association.
The first report, which was based on data from a major study involving more than 150,000 people from all walks of American society that examined the relationship between lifestyle, biology and the environment, found that consumption daily marijuana increased the risk of developing heart failure by approximately one-third compared to non-users. A research team from Medstar Health, a nonprofit health provider in the Baltimore-Washington metropolitan area, found that among 156,999 healthy people they followed, those who used marijuana had a 34 percent higher risk of develop heart failure during the 45 months of the study, compared to those who reported that they had never used marijuana. This risk was the same regardless of age, sex, or smoking history, and findings from the study, part of the National Institutes of Health's All of Us research program, suggested that coronary artery disease was the pathway through which daily marijuana use could lead to heart failure.
Argentina's central bank said China has authorized a free-access currency swap line totaling $6.5 billion, part of a broader deal the country has been using to help defend the embattled local peso.
The agreement with China helps Argentina increase its depleted foreign currency reserves while it is going through a major economic crisis, with annual inflation exceeding 130% and the central bank's dollar reserves reaching negative levels.
Wednesday's measure effectively increases the amount that Argentina can access as part of the swap line formalized in early 2023.
"China has increased the amount and instead of 5 billion dollars we are receiving 6.5 billion dollars," said Alberto Fernández, from the Asian country, where he is on an official trip. "
Every time we went through difficult times, Xi Jinping's government gave us its support," Fernández added. "This is an important step so that production (in argentina) does not stop.
" This is the second line of exchange with China activated during Fernández's presidency. According to an official source from the bank, the total amount of the swap line amounted to 47 billion yuan.
The problem is that it is not said that it is a loan, and it accrues interest that no one knows about.
CÓRDOBA.– During the early hours of today, firefighters managed to contain the fires in the southern area of Punilla, in the province of Córdoba. The only active outbreak is in La Tomita, in the department of Tulumba, in the north. Yesterday was a day of anguish and despair because the heat, the wind rotations and the drought caused the flames to get out of control and take them to the edge of homes in the area of Carlos Paz, San Antonio de Arredondo and Cabalango.
The Secretary of Climate Risk Management of Córdoba, Claudio Vignetta, indicated that around 4 o'clock today the firefighters managed to contain the fire in Punilla. “At 4 o'clock some drops fell. We were working until 6 at El Fantasio, which was busy. “Everything is controlled, with an unstable perimeter,” he described.
In any case, he warned that there are planes flying over to audit the situation and ash guard. The little rain recorded cooled the land somewhat.
Last night the interim mayor of Cabalango, Carla Bruno, ordered the town to be evacuated. The flames caused an environmental disaster, in addition to the anguish and fear of the residents since the fire reached some houses and surrounded the Villa Piren complex. About 11 fire crews were deployed to the scene.
Yesterday afternoon, the most desperate situation was experienced in the vicinity of Villa Carlos Paz, where the flames gained strength and height. “If it weren't for the firefighters and the police, we would all burn. I have never seen anything like that in my life. We managed to put it out with everyone's help. The fire was almost inside my house and surrounded us,” Ana, a neighbor from the Altos del Valle neighborhood, told the media.
At least 800 people were transferred to Tanti, since the flames threatened residents and the density of the air made it impossible to breathe.
In 2022, cyberspace entered a new round of transformation. Cybercriminals have become more sophisticated and their targets and attack methods have changed. Many governments are reviewing their cybersecurity strategies and increasing funding. When Russia found itself at the epicenter of events, the actions of both sides were met with a reaction from companies and the State. The demand for development and modification of information security systems has increased dramatically. It has become clear that real protection against cyber threats is a priority for all industries and levels of business. Who is most at risk, is it possible to create an "impenetrable" defense, and what threats are often overlooked? Find the answers to these questions in this article.
COMPANY SECURITY: A LOOK INSIDE
A great danger for companies is not only hackers attacking from the outside, but also internal threats. They are the same for all companies, regardless of their size and field of activity. These include basic errors made by employees when working with mail, negligence, internal actions, and cooperation with external suppliers and contractors. Statistics show that insider threats account for the majority of cyber incidents.
WHO IS THE BIGGEST DANGER?
According to new surveys, 53% in 2019 / 67% in 2022 / ?% in 2023 is the number of internal threats caused by malicious or careless actions of employees, which grows year after year: Internal threats come from primarily from employees, and the motives for their malicious actions vary. These can be employees who hold a grudge against company managers, dishonest employees who are looking for easy money and sell information about the company to competitors. And it happens that competitors or hacker groups introduce their spies into the company, and sometimes they can even be managers of different levels who have the appropriate level of access to the system. Thus, there are three main motives for internal attackers: financial gain, the desire to damage the company's reputation or the search for professional opportunities. However, it's often much simpler: if employees don't have basic skills to work securely with email, they can open an email from an unknown address and launch malware. Where do threats arise from? According to the latest studies, the following percentage of fraudulent schemes are implemented through: Messengers 34% / Removable media 25% / Cloud storage, personal email 8%.
MAIN SIGNS THAT A COMPANY IS AT RISK
Employees don't know what they are supposed to do to keep devices secure. For the sake of simplicity, employees violate the security policy. Sensitive data is sent to an unsecured cloud. Emails containing sensitive data are sent to a third party. Remote network and data access is possible outside of business hours. Multiple attempts to access blocked websites. Attempts to access USB ports and devices. Frequent requests for access to data unrelated to the employee's job responsibilities. Login from different IP addresses in no time.
6 STEPS TO PROTECT INFORMATION
• Step 1: Understand what information is confidential and important to the company, where it is stored, who and what level of access has access to this information and, most importantly, whether current protection measures are appropriate for the level of access. acceptable risk.
• Step 2: Introduce a trade secret regime in the company. To do this, it is necessary to develop a regulation on business secrets and specify a list of confidential information, the procedure for its accounting, storage and use. All employees are required to sign a confidentiality agreement.
• Step 3: Start monitoring data access, movements and user activity. It is necessary to limit the possibility of uncontrolled transfer of information to removable media.
• Step 4: Conduct employee training. In particular, it should include regular training on working with confidential information.
• Step 5: Use data encryption.
• Step 6: Protect endpoints from data loss, improve cybersecurity program. To do this, we must adopt a Zero Trust approach to data protection.
PROTECTION AGAINST INTERNAL THREATS
• Data loss prevention tool (DLP solution).
• Cloud Access Security Broker (CASB).
• Control and management of access to unstructured data (DCAP systems).
• Sensitive data labeling technologies.
• Account and access management (IdM/IGA).
• Access monitoring technologies for enterprise applications and databases (DAM systems).
• Control of privileged users (SafeInspect PAM).
• Multi-factor authentication (MFA) technologies.
• Single sign-on (SSO).
• Enterprise Mobility Management (EMM).
• Technologies to encrypt data on user endpoints, etc.
• Cyber literacy training for employees to identify signs of social engineering, phishing emails and reduce the likelihood of data breaches.

STOCKHOLM-- Norwegian author Jon Fosse has won the 2023 Nobel Prize in Literature, the Swedish Academy announced here today.
Fosse's immense body of work, written in Norwegian Nynorsk and spanning a variety of genres, consists of a large number of plays, novels, poetry collections, essays, children's books and translations, the academy said.
Fosse was born in 1959 in Haugesund, Norway. "While today he is one of the most widely performed playwrights in the world, he has also become increasingly recognized for his prose," the academy said in the news release.
In its justification, the Swedish Academy says, among other things, that Jon Fosse gives voice to the unsaid and, as paradoxical as it may seem, this is exactly how great literature can work. It is in the spaces, in the rhythm and in the silence between people where much of the tension lies in Fosse's prose and drama.
In reality, we are talking here about a form of classical existentialism, a recognition that man is fundamentally left to himself in this world. Everything else is incomprehension, volatility and distance.
In his later books, including the seven-volume (!) Septologien, Fosse twists his story in an almost ruthless literary way.
Memories and dreams, reality and fantasy come together in an incessant stream. The main character, Asle, is drawn towards the transcendent, in what eventually becomes a unique and evocative creed.
In a text that is written without a single period! It is very boldly done, but Jon Fosse orchestrates this entire work with symphonic assurance. Beneath this and other texts by Fosse, there is a sense of something precarious waiting to break through.
It keeps the reader attentive far forward in the chair and uses the rhythm and touch of the language to the fullest. It's compelling, it's dark, it's repetitive. You will never doubt that you are in a waterfall universe. No one else in Norwegian literature can imitate him in such artistic intransigence. But Norway is no longer the natural criterion for Jon Fosse.
Now he is up there on Parnassus, among the best writers living and deceased that the world has ever fostered! Jon Fosse has been writing books for 40 years, since his debut in 1983. Novels, stories, children's books, essays, poetry and, therefore, theater.
To this we must add the fact that he has translated several plays into the rich Norwegian Nynorsk, with a special fondness for Greek tragedies. We are talking here about a quite unique literary work. Fosse has never hidden the fact that he is characterized by a pietistic background, and the religious dimension has become increasingly evident in his literature. Ten years ago he also announced his conversion to Catholicism.
But anyone who thinks Jon Fosse only writes sensitive books about spirituality, anxiety and longing is shamefully mistaken. His books are also strongly sensual. Here you can smell the smell of birch wood, roast pork and scraped balls from the pages of the book. And in the eternal darkness of November to which Fosse so often adds his actions, there is a ray of light and pulse.
Jon Fosse is probably a global name, but he is also unmistakably Western. And through the darkness and the rain, there are still glimmers of Western humor.

This year's laureates "have managed to produce particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology," said the Royal Swedish Academy of Sciences.
STOCKHOLM-- Three scientists, Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov, won the 2023 Nobel Prize in Chemistry, "for the discovery and synthesis of quantum dots," the Royal Swedish Academy of Sciences announced today, Wednesday.
The 2023 Nobel Prize in Chemistry rewards the discovery and development of quantum dots, nanoparticles so small that their size determines their properties, the academy said in a statement.
"These smaller nanotechnology components now spread their light from televisions and LED lamps, and can also guide surgeons when removing tumor tissue, among many other things," he added. This year's winners "have managed to produce particles so small that their properties are determined by quantum phenomena.
The particles, which are called quantum dots, are now of great importance in nanotechnology," the statement said. "Quantum dots have many fascinating and unusual properties. Importantly, they have different colors depending on their size," said Johan Aqvist, chairman of the Nobel Committee for Chemistry.
In the early 1980s, Ekimov managed to create size-dependent quantum effects in colored glass. The color came from copper chloride nanoparticles, and Ekimov showed that particle size affected the color of the glass through quantum effects.
A few years later, Brus was the first scientist in the world to test size-dependent quantum effects in particles floating freely in a fluid.
In 1993, Bawendi revolutionized the chemical production of quantum dots, resulting in near-perfect particles. This high quality was necessary for them to be used in applications.
Quantum dots now light up computer monitors and television screens based on QLED technology. They also add nuances to the light of some LED lamps, and are used by biochemists and doctors to map biological tissue. Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication, the statement said.
"(I am) very surprised, unexpected and very honored," Bawendi said in the on-site telephone interview about his reactions. Bawendi, born in 1961 in Paris, France, earned his PhD in 1988 from the University of Chicago in the United States. He is now a professor at the Massachusetts Institute of Technology (MIT).
Brus, born in 1943 in Cleveland, United States, earned his doctorate in 1969 from Columbia University. He is now a professor at Columbia University.
Ekimov, born in 1945 in the USSR, obtained his doctorate in 1974 at the Ioffe Physical-Technical Institute, Russia. He was the chief scientist of Nanocrystals Technology Inc., United States.
The prize amount is 11 million Swedish krona (about 1 million US dollars) and will be shared equally between the three winners. (1 Swedish krona = 0.091 US dollar).
The capsule with samples from the asteroid Bennu separated from the OSIRIS-Rex probe before landing
A capsule containing soil samples collected on the asteroid Bennu on Sunday separated from the US OSIRIS-Rex spacecraft flying near Earth ahead of an upcoming landing, NASA said.
The separation was carried out at an altitude of 102 thousand km about four hours before landing. After re-entering Earth's atmosphere around 10:42 a.m. EDT, the capsule should land in 13 minutes using a parachute system at the Pentagon test site in the Utah desert, 122 km from the city of Salt Lake City.
The capsule will deliver about 250 grams of soil from the asteroid to Earth. After landing, it will be sent to NASA's Johnson Space Center in Houston, Texas.
The OSIRIS-REx spacecraft was launched in 2016 and arrived at the asteroid Bennu in December 2018. The probe was in orbit of the asteroid for two years, during which it was studied remotely.
Having approached the surface of the asteroid in October 2020, the probe touched down with the help of a manipulator arm.
Scientists hope soil samples from Bennu will provide new data on the formation of the solar system 4.5 million years ago. It is assumed that the asteroid's surface may contain matter preserved from the moment of its inception.
This is NASA's first mission to return soil samples from asteroids to Earth. After flying close to Earth, the OSIRIS-REx spacecraft will continue its journey to the asteroid Apophis to study it.
The OSIRIS-REx mission is named after the Egyptian god of the underworld, Osiris, and the asteroid Benn was named after a bird in 2013, symbolizing the resurrection of this god. According to calculations of the trajectory of movement, the asteroid Bennu, discovered in September 1999, has a chance of colliding with the Earth in the period from 2169 to 2199. NASA considers this object to be a potentially dangerous celestial body for the planet.
The mass of Bennu reaches 140 million tons, the diameter is 560 m. the fall of such a body to Earth would lead to catastrophic consequences. Illustration provided by NASA of the OSIRIS-Rex spacecraft on the asteroid Bennu.

How do you make a cell phone?
Cell phones have a wide variety of uses, from making calls and sending text messages to browsing the Internet and taking photos. In addition, cell phones are used to work, study, make online purchases, play video games and listen to music. Mobile phones are one of the most popular and used technological devices around the world. Since their invention, cell phones have evolved significantly with new features and designs. But have you ever wondered how cell phones are made? In this article, we will explain the step-by-step production process of cell phones. Materials necessary for its manufacture The manufacture of cell phones requires a large amount of materials. The most important components are the processor, RAM, screen, battery and case. In addition, other materials such as copper, aluminum, plastic, glass, gold and silver are needed.fa Industrial processes necessary for its manufacturing The cell phone production process is very complex and requires the intervention of several industries. Below are the processes necessary to manufacture a cell phone: 1. Design: The first step is the design of the cell phone, which includes the selection of materials and the definition of technical specifications. 2. Manufacturing of components: The components of the cell phone are manufactured separately in different factories. For example, the processor is manufactured in a semiconductor factory, the display in an LCD panel factory, and the battery in a battery factory. 3. Assembly: Once the components are ready, they are sent to the assembly factory where they are joined together to form the cell phone. This process includes soldering the components to the motherboard, installing the battery, and placing the case. 4. Testing: After assembly, each cell phone is subjected to rigorous quality tests to ensure that it works correctly. 5. Packaging: Finally, the cell phones are packaged and sent to the distributors. Main global cell phone manufacturers and where they have their factories The main cell phone manufacturers globally are Samsung, Apple, Huawei, Xiaomi and Oppo. These companies have factories around the world, including China, South Korea, the United States and Mexico. Samsung is the largest cell phone manufacturer in the world and has factories in South Korea, Vietnam, India, Brazil and China. Apple, for its part, manufactures the iPhone in China and the United States. Huawei has factories in China and Europe, while Xiaomi and Oppo have most of their factories in China. All consumer technology manufacturers are very wary of showing off their machinery. Perhaps because what for some would be showing their power, for them means exposing themselves to imitations. However, we investigate and can make known the production process of mobile phones, from the first filament to the final packaging. Accessing different factories where millions of smartphones are generated per month is not easy. Before going to the production room you must remove all metal, belts, jackets... even earrings and shoes. Wearing a white coat, rubber flip-flops and a hat that collects hair, everyone who enters the factory must pass through airport-style security arches. Once inside, the plant is divided into production lines in which units of the firm's smartphone are manufactured non-stop. “One every XX seconds”, as highlighted by the different guides of the different factories that opened their doors to us. It all begins in the area called 'SMT', the first phase of order preparation. It is an area where dozens of rolls similar to cinema films are accumulated, but instead of scenes they contain metal filaments that are the raw material for what will later become a high-performance smartphone. The motherboard is prepared in this first phase. All the following components are included with different machines prepared for each of them on the motherboard. A scan is made of each component and if there has been an error, engineers are called to solve the problem. The different robots place the insulator, the glue that ensures that if the phone falls to the ground it is protected, the element that balances the internal and external temperature, etc. Until now the mobile phone has not been touched by anyone. It is from this step that the technicians appear on the scene. A row of workers assembles the parts of several devices at the same time. They place the camera lenses and other external components such as the screen, the touch panel and the fingerprint recognition sensor. Once finished, we move on to 'testing' where the terminal is tested under “extreme” conditions to determine how it works.
