JWST helped detect the presence of tellurium and iodine from the gamma-ray burst GRB 230307A

Recent observations from JWST and ground-based telescopes have confirmed the presence of heavy elements in the ejecta of material from the gamma-ray burst GRB 230307A.

Classified as a kilonova, GRB 230307A is considered the second brightest gamma-ray burst. One of the notable consequences of kilonovae is the generation of heavy elements such as tellurium, which is classified as a metalloid in the periodic table. Scientists also suggest that iodine, essential for life on Earth, may be generated by kilonova gamma-ray bursts, since both elements are located next to each other on the periodic table of elements.

Tellurium is an extremely rare element on Earth, even rarer than platinum, and is used in various metal alloys, semiconductors, oil refining and solar cell production. Although rare on Earth, tellurium has been found in planetary nebulae and ancient stars. Recent observations have also shown the presence of iodine in these space objects.

Lasting 200 seconds, GRB 230307A was approximately 1000 times brighter than traditional gamma-ray bursts and is the second brightest gamma-ray burst ever detected. It was discovered in March 2023 by NASA’s FERMI space telescope, and subsequent observations were made using JWST’s infrared and spectroscopic instruments 29 and 61 days after the flare.

Kilonovae are the result of the merger of two neutron stars and are thought to produce rare elements that are significantly heavier than iron. The brightest kilonova was discovered in 2022 and named BOAT (Brightest of all time, the brightest of all time). Observations of gamma-ray bursts have been carried out for more than 50 years, the first was recorded on July 2, 1967, and confirmation of this event came in 1969. Gamma-ray flashes are classified into short and long, with short lasting less than two seconds and long lasting several minutes.

Scientists hope that with the use of JWST and ground-based observatories, it will be possible to detect and study even more kilonovae and expand our understanding of the synthesis of heavy elements in the Universe.

Three cheap smartphones and all without AMOLED Infinix Hot 40

In addition to the ultra-cheap Smart 8 HD smartphone, Infinix also presented a whole line of budget models: Hot 40.

It includes the junior model Hot 40i, basic Hot 40 and Hot 40 Pro. Pricing hasn’t been announced yet, but the company says they’ll all cost less than $200.

Hot 40 Pro, as expected, looks the most interesting. There is a camera with a resolution of 108 megapixels, a 120 Hz screen, and 8/128 or 8/256 GB of memory. The device is also equipped with a 5000 mAh battery with 33-watt charging, Helio G99 SoC and a 6.78-inch Full HD+ display.

The Hot 40 is similar to the older model, but it has a screen with a frame rate of 90 Hz, is based on the Helio G88 and a 50 MP camera. The remaining parameters are identical.

The younger model Hot 40i is more different. The heart here is the less productive SoC Unisoc T606, the basic amount of RAM is 4 GB, although there is also a version with 8 GB, the screen here has HD+ resolution with a diagonal of 6.56 inches and supports a frame rate of 90 Hz, and charging power is limited to 18 W. Other parameters are the same as Hot 40.

It is also worth noting that all models received IPS screens.

In 2024 Huawei will rewrite industry history The company will

For almost five years now, Huawei has been under strict American sanctions, and all this time the company has worked tirelessly. Now it may be time for a major push. At least the words of Yu Chengdong, CEO of Huawei’s consumer business group, indicate exactly that.

At Huawei’s annual reporting conference, Yu Chengdong promised to rewrite the history of the industry and announced completely new revolutionary devices. The top manager said the following verbatim: “When the time comes, you will see how we can rewrite the history of this industry. I hope to continue to exceed everyone’s expectations and do what others can’t even think of, or what they can’t do, or even what they don’t dare do.” And we were not talking about some distant future, but about 2024.

There are no specifics yet. But one of the breakthroughs could be the release of our own single-chip systems with 5G support – very well-established insiders are talking about this. Moreover, SMIC is rumored to be preparing to produce 5nm SoCs for Huawei. If this really happens, it can be called a breakthrough for the entire period of Huawei’s existence under sanctions. And next year, new, and far from trivial, cars are expected to be released on Huawei platforms and with the proprietary HarmonyOS operating system.

Infinix has announced the Smart 8 HD smartphone with a price of just $75. At the same time, the device is equipped much better than many smartphones priced at $100-120.

But it’s worth starting not even with this, but with design. As you can see, Infinix does not betray itself and even made an ultra-budget smartphone so that it stands out: the back cover seems to have a relief pattern. The company itself even uses the expression “premium design,” but this, of course, is on its conscience.

From a technical point of view, the device is not bad, and for such a price it is very good. It is based on the Unisoc T606 SoC, which scores about 240,000 points in AnTuTu 10. There is 3 GB of RAM, 64 GB of flash memory, a 13-megapixel main camera and a 5000 mAh battery. And the 6.6-inch screen with HD+ resolution also supports a frame rate of 90 Hz. In addition, there is an element that imitates the Dynamic Island of the iPhone.

It remains to add that the dimensions here are 164 x 75.6 x 8.5 mm with a weight of 184 g.
