LG to unveil world's largest 97-inch OLED TV at IFA 2022
LG Electronics said on Monday it will showcase the world's largest organic light-emitting diode (OLED) TV at the upcoming electronics show in Berlin, as it looks to expand its portfolio of large OLED TVs and solidify its leadership in the premium TV segment. LG said it will unveil a 97-inch OLED TV, or the OLED evo Gallery Edition, among others, at the IFA 2022, set to open on Friday in Germany. The South Korean tech company said the model will be available in the market in the fourth quarter, the peak season for consumer electronics and home appliances amid holiday shopping. With the arrival of its biggest-ever screen size, LG's OLED TV lineup for this year offers 42, 48, 55, 65, 77, 83, 88 and 97-inch options, reports Yonhap news agency. OLED TVs' self-lit pixels can be turned on and off individually, leading to innovative form factors, such as flexible and rollable TVs, LG said. The global electronics trade show will come at a time when global tech companies have been struggling to combat lacklustre consumer demand after two years of a pandemic-fuelled surge in demand for personal devices and home appliances. The Ukraine-Russia war, runaway inflation and expensive borrowing costs all added to the woes. TV manufacturers have been doubling down on their push in the high-end, more profitable segment, where demand slowed down less markedly than in the budget category. In the premium TV segment, in which TVs are priced at $2,500 or more, Samsung Electronics Co. took up a 53.6 per cent market share, followed by LG at 21.5 per cent and Sony at 17.2 per cent, according to industry tracker Omdia. In the OLED TV segment, LG kept its solid No. 1 spot by selling 1.69 million units in the first half, about 62 percent of all global OLED shipments. Omdia predicted OLED TVs will account for 55 percent of the European premium TV market this year. The figure is expected to rise to 66 percent by next year, it added. OLED TVs accounted for 33.2 percent of all TV sales by LG in the first half. Read the full article
New updates from Jupiter
The researchers were surprised when NASA's Juno spacecraft recently flew over the Jupiter poles as if they had never before seen a giant planet.
The images were different in planetary exploration history.
On 4 July 2016, Juno entered orbit and later found Jupiter's pole covered by storms of almost continental size, which had been densely clustered and rubbed together in a mental swirling.
"It's like a whole new Jupiter," says Scott Bolton, Southwest Research Institute's lead investigator, Juno. "The clouds were wonderful."
What is striking about Jupiter's polar storms is that each pole actually has several cyclones. Thus, Jupiter was observed to have as many as eight giant swirls moving simultaneously on his north poles and as many as five on his south pole instead of having one polar vortex-like Earth.
Even more incredible things lurk below. Researchers have long wondered about the hidden interior of the giant planet. How far do the storms of Jupiter's continent go down? And what's the exotic material near the core of the planet?
In Jupiter, high temperatures and crushing pressures transform the abundant supplies of gaseous molecular hydrogen by Jupiter into an exotic form of material called liquid metallic hydrogen. Think of it as a mashup of nuclear nuclei in a freely moving sea of electrons. The strong magnetic field of Jupiter most certainly comes from dynamo action in the interior of Jupiter, which converts the motion of this electrically driving fluid into magnetic energy. The exact location inside the interior is a mystery that researchers continue to work to resolve.
A magnetic field of a planet becomes weaker as you get away from its core. The magnetic field of Jupiter is 10,000 times stronger than the Earth! The magnetic field of Jupiter is only 20 times larger on the cloud tops, however than what we measure on the Earth's surface. This is because Jupiter is so much bigger than Earth.
Astronomers are known for the fact that Jupiter has the highest magnetic planetary field in the solar system. Jack Connerney, Juno Senior Investigator at NASA's Goddard SPC, said, "Juno's magnetometers show that the magnetic field of Jupiter is even stronger than we thought."
"In addition, the magnetic field looks lumpy," he said. "In some places, it is stronger and in others, it is weaker. This uneven distribution indicates that dynamo action close to the surface could generate the field above the layer of metallic hydrogen."
The magnetic field of Jupiter is home to the largest and most influential auroras in the planetary system. In contrast to the Earth that lights up in response to global temperature, Jupiter produces its own auroras. It accomplishes this by leveraging the power of its magnetic spinning field. Induced electric fields speed up particles to the pole of Jupiter, where aurora action occurs.
Juno's Microwave Radiometer, which helps to measure thermal microwaves which radiate from the deep recesses of the planet, reveals the structure of several hundred kilometers under thick clouds of Jupiter, provides alternative insight.
Recent results from Juno's Gravity experiment show that Jupiter's emblematic belts and zones rotate at depths between 3000 and 5,000 km as a series of cylinders. Below this depth, Jupiter seems to be rotating as a rigid body.
There are still new discoveries about Jupiter. Bolton states, "Juno floats to Jupiter every 53 days and gets doused with a bolt of data. "It's always new to discover."

Read UPSC Current affairs and Daily News Analysis from Best IAS Academy in Bangalore Vignan IAS Academy IIT Bombay has developed a platform named World Wide Help (WWH) which can be used to connect people seeking medical help with helpers, such as doctors
About: The WWH platform can be used with an app or a phone. The user simply calls a dedicated number and can input basic data such as the age of the person in need of help and whom they wish to solicit help from. They can supply the phone number, too. This is registered as a task in the app and assigned to a primary helper who is a junior doctor or medicare professional. Further, the task may be re-designated by the primary helper to a senior doctor, who is the second level of helper.

The treated recyclable waste may finally be sent for disposal in a secured landfill or for recycling. Since 1998, the CBWTF as an option for treatment of bio-medical waste also been legally introduced in India. There were 154 CBMWTFs in 17 states and Union Territories, according to affidavits filed by their chief secretaries at the National Green Tribunal (NGT) between January and July last year.

About: They have also associated such Li enhancement with central He-burning stars, also known as red clump giants, thereby opening up new vistas in the evolution of the red giant stars. This is an important discovery that will help to eliminate many proposed theories such as planet engulfment or nucleosynthesis during the red giant evolution in which helium at the center is not burning. Important Info : Lithium (Li), is one of the three primordial elements, apart from Hydrogen and Helium (He), produced in the big bang nucleosynthesis (BBN) whose models predict primordial Li abundance (A(Li) ~2.7~dex).In general, stars are considered as Li sinks. This means that the original Li, with which stars are born, only gets depleted over stars’ life-time as Li burns at relatively very low temperatures of about 2.5X106 K – a range which is easily encountered in stars.
