An « exquisitely preserved » embryo has been found inside a fossilised dinosaur egg.
The discovery, dubbed « Baby Yingliang », is believed to be between 66 and 72 million years old, and was found in the Late Cretaceous rocks of Ganzhou, China.
Professor Steve Brusatte, part of the research team, said: « This dinosaur embryo inside its egg is one of the most beautiful fossils I have ever seen. » The embryo is believed to be a toothless theropod dinosaur, or oviraptorosaur – a group of feathered theropods, closely related to modern-day birds.
« Unity doesn’t mean we all have to believe the same thing, but it’s essential that we respect each other, and have faith in each other, » Joe Biden said in his video message to America. deeply divided.
The president and his wife Jill Biden are due to visit, this Saturday, the three emblematic places of the attacks of September 11, 2001: in New York, on the Pentagon site and in Pennsylvania, where a plane hijacked by jihadists crashed. twenty years ago.null
But it is not expected that Joe Biden, much criticized for his management of the withdrawal from Afghanistan and who is struggling to contain the Covid-19 pandemic, to speak in public during the ceremonies . He will preside – in silence, therefore – the tribute to the 2,977 dead (including 2,753 in New York alone) from the impressive Manhattan memorial built at the foot of new skyscrapers, on « Ground Zero », where s ‘once stood the twin towers of the World Trade Center.
A musical tribute, several minutes of silence and the reading of all the names of the victims are planned near the two huge black basins which replaced the base of the towers. The commemorations will start at 8.46am in the United States – the time at which the first plane hacked by five of the 19 terrorists had struck the north tower of the World Trade Center
According to the company, this step is taken in order to protect the privacy of user accounts, which can no longer be as secure as on the most recent versions.
The smartphones running Android 2.3.7 or earlier will no longer have access to Google services from September 27, the company announced Tuesday. In order to justify this decision, Google has put forward its « permanent efforts to ensure the safety of users », their accounts can no longer be as secure as on the most recent versions, reports Phonandroid .
Thus, the Californian giant recommended to those concerned to opt « for a more recent version of Android, 3.0 » or a later version. Among the Google applications that will no longer be available from September 27 include Google Maps, YouTube and Gmail. After the deadline, the system will no longer recognize the usernames and passwords of clients using an older operating system and an error message will be displayed.
Possibility to go through the web version of the applications
Owners of a smartphone that does not allow an Android update will still be able to continue using some of Google’s portals through their web versions. For example, their Google account will be accessible via the URL myaccount.google.com and their Gmail email on mail.google.com. The other solution is to buy a newer terminal, added Phonandroid .
Users of Android version 2.3.7 or later will also be unable to log in with their username and password if they create a new Google account on their smartphone or if they delete their account and try to add it. It also won’t work if they reset their phone to factory settings or change their password.
“What we are seeing now is an industry created to hack these smartphones, and go beyond what we knew existed. These people take full control of the phone and turn it against the person who bought it, but doesn’t really own it anymore , ” Snowden said in an interview with The Guardian , partner of the World on“ Project Pegasus ”.
The Gates, who have three children, announced that they would continue to « work together in their foundation », the Bill and Melinda Gates Foundation which fights against poverty and disease, but that they did not believe « could any more evolve. together as a couple ”. They met in the late 1980s when Melinda joined Microsoft.null
In the famous press release, the spouses do not say anything about the reasons that push them to separate.
Bill Gates is, according to the latest Forbes ranking, the fourth richest man in the world, with a fortune estimated at $ 124 billion. It places him behind two other Americans, Jeff Bezos and Elon Musk and Frenchman Bernard Arnault, and ahead of Facebook founder Mark Zuckerberg.

About seven months after taking off, NASA’s last vehicle, Perseverance, will still have to survive « seven minutes of terror, » as the ultra-perilous maneuver preceding its landing on Mars is dubbed.
The chosen location, Jezero Crater, is the most dangerous landing site ever attempted. In seven minutes, the rover must go from a speed of 20,000 km / h to zero.
The landing will take place at 8:55 p.m. GMT Thursday (3:55 p.m. Washington).
-130km: entry into the atmosphere-
Ten minutes before entering the Martian atmosphere, the vessel separated from the cruise stage which supplied it with fuel during the trip.
It is then only composed of a rear shield, a heat shield at the front, and, caught between the two, the descent stage, connected to the rover itself.
At about 130km altitude, it enters the atmosphere at a speed of 20,000km / h, causing friction raising the temperature to 1,300 ° C. The heat shield protects the rover from this infernal heat.
-11km: opening of the parachute-
But the atmosphere is not enough to slow the ship enough, which is still going at 1,500 km / h.
At about 11km altitude, at an opportune moment calculated according to the distance remaining to the landing place, a huge supersonic parachute 21 meters in diameter, located in the rear shield, is deployed.
This slows down the ship to about 300 km / h.
-9km: heat shield released-
20 seconds after opening the parachute, the heat shield is released: the rover it was protecting is exposed for the first time to the Martian atmosphere.
A whole new technology, called “Terrain Relative Navigation” (TRN), comes into play: the images recorded live by the cameras of the vessel are compared to maps recorded in its system, where the dangerous zones to be avoided are pre-defined. Taking these data into account, the ship decides on the final landing place.
-2km: retro-propelled phase-
At an altitude of around 2km, the rear shield – and its parachute – are dropped.
The rover is no longer attached to the descent stage, equipped with eight motors pointed downwards, which light up to finish slowing it down. After performing a maneuver to get away from the parachute, the rover ended up descending vertically, right above its landing site.
-20m: separation of the rover-
At about 20m from the ground, it reached a speed of 2.7km / h, slower than that at which a man walks. The rover then descends along the cables thanks to a system of pulleys, during a final fifteen seconds (stage called « skycrane »).
The vehicle deploys its wheels at this time. When the latter feel the ground, the lines are cut and the descent stage makes a final push to crash as far as possible.
Because of the transmission delay between Earth and Mars, when the landing will be confirmed by NASA, it will actually have taken place several minutes earlier.
The US president could ask the Department of Justice to stop scheduling new executions. Before an abolition at the federal level?
Joe Biden is the first sitting president to speak publicly against the death penalty, a sentence still in effect across the Atlantic. Barely installed in the White House, the Democrat would have discussed the possibility of asking the Department of Justice to stop the programming of new executions .
This information remains confidential, and no official announcement is planned – White House spokeswoman Jen Psaki assured it. If this measure were to be confirmed, it will certainly push supporters of the abolition of the death penalty to lift the pressure they exert on Joe Biden . But they will quickly want the US president to go further by closing, for example, the death row that belongs to the federal government, located in Terre Haute, Indiana. And why not, that he abolish the death penalty altogether from American laws.
The position of the 46th American president contrasts with that of his predecessor. Throughout his tenure, Donald Trump has been a staunch supporter of capital punishment , and everything has escalated over the past six months. 13 people were thus executed by the federal justice – unheard of in 120 years. The former president even appeared to hasten the executions as his departure from the White House arrived . The last execution took place just four days before Joe Biden was inaugurated president. Americans are therefore very aware of the issue.
A divisive decision
One situation particularly shocked the Americans: it was prisoners suffering from mental illnesses who were executed. It therefore seems natural that Joe Biden wants to return to the practice of the Obama era – the latter had unofficially prohibited executions from 2014. But he did not dare to go all the way, which allowed Donald Trump to enforce sentences.
Joe Biden could, however, attract the wrath of many Republicans, in favor of capital punishment. And even some members of his own camp might blame him, believing it to be political suicide . Not to mention that this decision would save some controversial criminals, such as Dylann Roof, a white supremacist who killed nine black parishioners who attended a small church in South Carolina. It might be difficult for Joe Biden to explain to the families of the victims why the murderer of their loved ones must not die.
Towards an abolition of the death penalty at the federal level?
Supporters of the death penalty are declining – they now represent only half of Americans. But many still want to keep the possibility of sentencing the perpetrators of terrorist attacks to death – the author of the Boston Marathon bombs, moreover, was found guilty and sentenced to death by his jury. Another court commuted the sentence – but the Trump administration has appealed. The Biden administration will soon have to decide whether to pursue this appeal, or whether to accept this sentencing change.
The abolition of the death penalty at the federal level is in any case a campaign promise of candidate Biden. He didn’t give a lot of details though, remaining very factual. Presumably he is feeling a little guilty and could reallyunravel the laws around the death penalty – to which he nevertheless contributed as a senator. In 1994, it was he who proposed to expand the range of federal crimes punishable by capital punishment. Supporters of ending the death penalty know he has an Achilles heel and they are unlikely to let go until they get a guarantee.
INVESTITURE – D-Day for Joe Biden: the new American president is sworn in this Wednesday, January 20 at noon local time . Donald Trump, whose departure is imminent, has granted his presidential pardon to 73 people before leaving the White House.
TRUMP SOON ON THE START
The future ex-tenant of the Oval Office has already packed his bags and will leave the White House at 8 am aboard the presidential helicopter. Head to Andrews Air Force Base, where a military ceremony awaits him. Donald Trump will then travel for the last time aboard Air Force 1. He is due to land in Florida when the new president-elect Joe Biden will be sworn in at the foot of the Capitol. The Republican billionaire will return to his residence in Mar-a-Lago, where a moving truck was seen last Monday.
With the surge in Tesla’s securities on the stock market, of which he holds 18%, the whimsical 49-year-old entrepreneur has passed Jeff Bezos, the boss of Amazon.
Elon Musk, the boss of high-end electric vehicle maker Tesla, rose to the rank of the richest man in the world on Thursday (January 7) thanks to the soaring stock market shares, according to Bloomberg News calculations .
With Tesla’s stock market soaring , in which he owns 18%, the whimsical 49-year-old entrepreneur, who also runs SpaceX, passed Jeff Bezos, the Amazon boss who held the title of richest man in the planet since 2017.
While Tesla stock, which saw its value more than 7-fold in 2020 and still rose sharply on Wall Street on Thursday, the South African-born engineer’s fortune hit $ 188.5 billion soon after. the opening of the session, exceeding that of Jeff Bezos by 1.5 billion.
The enthusiasm of investors
The day before, Tesla broke the $ 700 billion mark for the first time at the close as the stock finished up almost 3% to $ 755.98. Thursday morning, the action was close to $ 800 climbing 5.7%.
The group’s sales, however, remain a long way from traditional manufacturers: Tesla only sold 499,550 cars in 2020, a long way from Volkswagen, for example, and its 11 million vehicles sold in 2019.
But Tesla is benefiting from investor enthusiasm for electric vehicles and the fact that it has managed to make money for five consecutive quarters, which allowed it to enter the prestigious S&P 500 index in December.
