Internet advertising earthquake: Google began to "eliminate" cookies

Chrome, which accounts for 65% of global internet traffic, began partially disabling third-party cookies on Thursday, with the ban set to be fully implemented by the end of the year. Advertisers who rely on cookies to track users and serve relevant ads will be forced to adapt to painful changes. The $600 billion online advertising industry changed overnight.

For the first time, researchers have cracked the emotions behind a chicken's clucking

A study led by the University of Queensland found that humans can tell if a chicken is excited or unhappy by its crow. Professor Joerg Henning of the University of Queensland's School of Veterinary Sciences said researchers investigated whether humans could correctly identify the background of the cries or gurgling sounds made by domestic chickens, the world's most common farmed species.

The Nasdaq 100 index fell for five consecutive days Apple has become the big tech stock with the least bullish rating on Wall Street

U.S. stock shorts lost nearly $195 billion last year, and Tesla lost $12.2 billion in short positions, ranking first

According to financial analyst firm S3 Partners, the paper losses of short positions in U.S. stocks reached nearly $195 billion throughout 2023, offsetting about two-thirds of the nearly $300 billion they made in the 2022 market crash. This figure is higher than the accumulated loss of about $142 billion in 2021 by US stock bears, but lower than the $242 billion loss in 2020.

The price war has recurred, and Carrefour has removed several Pepsi products from the shelves due to price increases

Carrefour has reportedly told customers in four European countries that it will no longer sell a number of products under PepsiCo's brand because they are too expensive. It's the latest price tug-of-war between retailers and global food giants. A spokesman for French supermarket giant Carrefour said that from Thursday, PepsiCo product shelves at Carrefour stores in France, Italy, Spain and Belgium will post notices saying that the store will no longer sell the brand's products "due to unacceptable price increases."

Research suggests that the magnetic field was primordial even within a second of the Big Bang

We don't know how magnetic fields are formed. Now, new theoretical research tells us that the invisible part of the universe may help us discover magnetic fields, suggesting that magnetic fields were formed primitively, even within a second of the Big Bang. The dark matter scattered throughout the universe can be used as highly sensitive detectors of the primordial magnetic field. This is the conclusion of a theoretical study conducted by SISSA published in the journal Physical Review Letters.

T cells become a source of power in predicting skin cancer

A groundbreaking study revealed that Vd1-gd T cells can show how likely a patient is to respond to cancer immunotherapy, paving the way for more targeted and effective treatments. Researchers at King's College London, the Guy and St Thomas Hospital Trust and the Francis Crick Institute have found that a type of immune cell helps predict which patients are likely to benefit the most from cancer immunotherapy.

Illuminating the Unknown: A Breakthrough in Ultrafast Electron Dynamics

A breakthrough study by a Swedish-German team tracks ultrafast electron dynamics with unparalleled accuracy, opening up new avenues for nanomaterials and solar cell research. When electrons move through a molecule or semiconductor, their time scale is unimaginably short. Swedish-German research teams, including physicist Dr. Jan Vogelsang at the University of Oldenburg, have made significant progress in better understanding these ultrafast processes: Researchers have used laser pulses to track the dynamics of electrons released from the surface of zinc oxide crystals with spatial resolution at the nanometer level and temporal resolution previously unattainable.

The FTC is offering a $25,000 prize for ways to detect cloned voices or related technologies

Modern AI-generated tools that can mimic real human voices are impressive and worrying at the same time. From phishing scams to election interference, at least one of any entertaining or practical apps is malicious. Now, the U.S. Federal Trade Commission (FTC) has also taken note of this and has taken its first action. Earlier this week, the committee began accepting entries for the Voice Cloning Challenge, according to Bleeping Computer.

The new "smart tweezers" select specific strains from the microbiome and sequence their genomes

Researchers have developed a smart tweezer that picks out specific bacterial strains from trillions of microbiomes and sequences their genomes in a more cost- and resource-efficient way than existing methods. This versatile tool enables precise research into the microbiome and enables breakthroughs in disease diagnosis and treatment.

China uses 22nm to create a 256-core chip with a target of 1600 cores

The Institute of Computing Technology of the Chinese Academy of Sciences has already created large chips with up to 256 cores, and the future goal is to achieve up to 1,600 cores, for which the entire wafer, that is, "wafer-level chips", will be used. Named "Zhejiang", the chip adopts the chiplet layout that has become popular in recent years, divided into 16 chips, and each chip has 16 RISC-V architecture cores, a total of 256 cores, all of which are programmable and reconfigurable.

China and Russia opened up quantum encrypted communication for the first time The distance is as long as 3,800 kilometers

Scientists from China and Russia have joined forces to successfully test ultra-long-range, "full-cycle" quantum encrypted communication between the two countries, the first of its kind. It is reported that the test was carried out on March 1, 2022, using the Zvenigorod ground station near Moscow, Russia, and the Nanshan ground station near Urumqi, Xinjiang, China, which are about 3,800 kilometers apart.

In 2023, there will be as many as 129 earthquakes of magnitude 6 or higher, slightly higher than in previous years

According to the data query of the China Earthquake Network, there will be as many as 129 earthquakes of magnitude 6.0 and above in the world in 2023, of which 19 will be of magnitude 7.0 and above, and the maximum magnitude will be 7.8, which will occur in Turkey on February 6, 2023, and two consecutive earthquakes on the same day. Among them, there were 14 earthquakes of magnitude 7 or higher in the first half of the year, accounting for almost three-quarters of the whole year.

Astronomers have found that magnetic fields are fairly common in massive star systems

A new study reveals that magnetic fields are common in star systems with large blue stars, challenging previous perceptions and providing new insights into the evolutionary and explosive nature of these massive stars. Astronomers from the Leibniz Institute for Astrophysics (AIP) in Potsdam, the European Southern Observatory (ESO), and the Kavrey Institute and Department of Physics at the Massachusetts Institute of Technology have found that magnetic fields are much more common than scientists previously thought in multiple star systems with at least one giant hot blue star.

Chinese researchers have successfully revealed the evolution history of the stratified structure of the impact crater in the Elysion Plain on Mars

The reporter learned from the Institute of Geology and Geophysics of the Chinese Academy of Sciences on the 4th that based on the observation data of the Mars Orbit Shallow Detection Radar (SHARAD), mainland researchers successfully revealed the evolution history of the layered structure of an impact crater in the Elysion Plain of Mars. Further analysis shows that Mars had a strong aeolian effect in the Late Amazon. The research results were published in the journal Science China: Earth Sciences.

Steam, the largest PC game publishing platform, released more than 14,500 games in 2023

That's an average of 40 games per day, or an average of 50 games per working day if you exclude the weekends. That's more than 2,000 games from 2022 and nearly 5,000 games from five years ago. It's impossible for the gaming media to evaluate all games, and most of them are junk games, either quickly made using off-the-shelf asset flips, or they may be small adult games. Valve doesn't censor the quality of the game much (except in the case of The Day Before), and anyone can release a game on Steam for as little as $100. A similar phenomenon exists in app stores such as the Google Play Store.

Bacteria that are so large that they can be seen without a microscope

Epulopiscium viviparus is not all bacteria created equal. Most bacteria are single-celled and small, only a few ten-thousandths of a centimeter long. But the bacteria of the Epulopiscium family are large enough to be seen with the naked eye, 1 million times larger than their more famous cousin, E. coli. A breakthrough study of the giant bacterium Epulopiscium viviparus has shown that it produces a unique energy that has the potential to be used in future algae utilization.

Breaking the Boundaries of Astrophysics: LST-1 Discovers the Most Distant, Energetic Active Galaxy Nuclei (AGNs)

On December 15, the Large Telescope (LST) Cooperative announced through the Astronomical Telegraph (ATel) that LST-1 had detected the OP 313 source at very high energy. Although OP 313 has been known at lower energies, it has never been detected above 100 GeV, making this the first scientific discovery of LST-1.

According to a study published in the journal Nature, researchers have found the oldest evidence of photosynthetic structure to date in a 1.75-billion-year-old set of microfossils

This finding helps to reveal the evolution of oxygen-producing photosynthesis. Direct evidence of the fossilized photosynthetic structure of an algae (Navifusa majensis) has been discovered and demonstrated: this microstructure is thylakoids, a membrane structure inside plant chloroplasts and some modern cyanobacteria. Researchers identified the structure in fossils from two sites, the oldest from Australia's McDermot t-group, which is 1.75 billion years old. This means that photosynthesis may have evolved sometime 1.75 billion years ago.

Orange España, Spain's second-largest mobile operator, suffered a serious network outage on Wednesday after hackers obtained the weak password "ripeadmin" to log in to the accounts it uses to manage the global routing table

Orange's account username is [email protected] and password is ripeadmin at the RIPE Network Coordination Center. An investigation by security firm Hudson Rock found that the account credentials had been stolen by an infostealing malware installed on Orange employees' computers last September and sold online. The hacker, who goes by the pseudonym Snow, posted screenshots of Orange's management account on social media. Snow made changes to Orange's global routing table after logging into its account, most of the changes had no impact on network traffic, as the routing addresses were all within Orange's own autonomous system AS12479, but one of the changes, 149.74.0.0/16, caused a problem where it set the maximum prefix length to 16, causing smaller routes using that address range to be invalid, such as 149.74.100.0/23, which was considered invalid and filtered out. BGP expert Doug Madory thinks hackers are just spoofing. The hacker's alteration of the global routing table was quickly blocked by RPKI (Resource Public Key Infrastructure) - other backbone operators rejected the hacker's routing announcement.

According to data released by the Japan Meteorological Agency, the average temperature in 2023 was 1.29 degrees Celsius above normal (the 30-year average until 2020), the highest since statistics began in 1898

The previous record was 0.65 degrees Celsius higher in 2020, and 2023 significantly breaks this record. In 2019~2023, it took the top five in the history of observation. According to the Japan Meteorological Agency, in addition to global warming, westerly winds from spring to autumn are more northerly, making Japan more likely to be covered by warm air, and the strong force of high pressure in southern Japan is also an important reason. Likely due to the impact of high temperatures, the average sea surface water temperature off the coast of Japan is also expected to reach a new high.

According to a study published in the journal Nature Communications, the researchers believe they have found the cause of tiredness, discomfort and pain after exercising in long COVID patients

The study subjects were 25 patients with long COVID and 21 patients who had fully recovered from infection who exercised on a sports bike for 10-15 minutes, taking blood samples and skeletal muscle biopsies one week before and the day after. The researchers found that long COVID patients had a higher proportion of white fibers in their muscles and fewer mitochondria and capillaries in white fibroblasts than healthy participants. And mitochondrial function was also weaker in patients with long COVID than in healthy participants. The results of the study partly explain the low exercise capacity of patients with long COVID. Researchers say people with long COVID should not do strenuous exercise. Strenuous exercise can damage muscles and worsen metabolism, leading to muscle pain and fatigue for a few weeks after a workout.

U.S. EV sales reached a record 300,000 units in the third quarter of 2023, but growth slowed significantly

EV manufacturers need price cuts, yet inventories are still growing. Major EV makers have reduced investments: Ford plans to invest $15 billion in EV production but $12 billion of that is delayed, General Motors has delayed production of key EV models and scrapped a $5 billion partnership with Honda to produce cheap EVs, and Tesla has delayed plans to build a factory in Mexico. Auto industry executives have even declared that driving car electrification in the U.S. won't work. Analysts believe the reasons include inadequate charging infrastructure and the high cost of electric vehicles. The reason why it is too expensive is that American manufacturers are keen to produce larger cars, and the popular electric cars in the United States are also large SUVs and trucks, and such cars require larger batteries, which increases the cost. Data shows that the average price of electric vehicles in the United States in September 2023 was $50,683, down 22% from the same period last year, but still 28% higher than gasoline vehicles.
