A time capsule at West Point that was initially thought to contain only dust actually held hidden treasure. The lead box, believed to have been placed by cadets, contained six silver American coins dating from 1795 to 1828 and a commemorative medal. The discovery was made by West Point archeologist Paul Hudson, who carefully sifted through the sediment in the box. The find confirms the theory that the box was left by cadets in 1828 or 1829.from Science News - Times of India https://ift.tt/OvsF8h9
A neurosurgeon in Australia discovered a live worm, measuring 8 centimeters, in a woman's brain during a biopsy. The worm was identified as the larva of an Australian native roundworm not previously known to be a human parasite. The woman had been experiencing symptoms of forgetfulness and depression for three months before the discovery.
A woman in Australia underwent surgery to remove an 8cm-long parasitic roundworm from her brain. The 64-year-old woman had been experiencing memory lapses and depression, in addition to other symptoms, and was referred to Canberra Hospital. Doctors discovered the roundworm, identified as 'Ophidascaris robertsi', in her right frontal lobe.

The Indian Space Research Organisation (ISRO) successfully landed the Vikram lander on the Moon's south pole, marking a significant achievement after the Chandrayaan-2 lander crash in 2019. The scientists at Isro had worked diligently for four years to ensure the lander's success, conducting various tests and strengthening its legs. Prime Minister Narendra Modi, who was attending the Brics summit in South Africa, closely watched the landing and congratulated the scientists on their achievement. The country celebrated the momentous occasion with joy and enthusiasm.
The senior scientists at ISRO celebrated the successful landing of Chandrayaan-3 after years of hard work. ISRO Chairman S Somanath played a crucial role in the mission's success, implementing a strategy focused on eliminating failures. Project Director P Veeramuthuvel, Deputy Project Director Kalpana K, and Directors Nilesh M. Desai, S Unnikrishnan Nair, and M Sankaran also contributed to the mission's success.
The lunar south pole has become important due to its potential for scientific research and resource exploration. The region contains water ice in permanently shadowed craters, making it a valuable resource for future missions. It also features craters that preserve a fossil record of the early solar system, providing insights into its history.
India is set to make history by landing a probe in the polar region of the Moon. The Chandrayaan-3 lander, named Vikram, is scheduled to touchdown on Wednesday, followed by the release of the rover named Pragyan. If successful, India will be the first to land close to the lunar south pole. Vikram has been equipped with sturdier legs to withstand landing velocities.
India's Chandrayaan-3 mission is set to land on the Moon's surface on Wednesday, marking a major achievement for the country. After landing, the rover will begin its operations for one lunar day, collecting data from its instruments. The lander will also carry out measurements and study the lunar crust and mantle. The mission aims to explore the unexplored lunar South Pole, with the hope of finding evidence of water, which could potentially be a valuable source of clean energy.
With just two days left before Chandrayaan-3 attempts a soft landing at the Moon's south pole, the Indian Space Research Organisation (ISRO) on Monday said the lander module has established a two-way communication with the orbiter of the mission's predecessor Chandrayaan-2.
A new study offers insight into the cognitive decline of normal ageing, shedding light on how ageing contributes to neurodegenerative conditions such as Alzheimer's and Parkinson's diseases.
Russian space agency Roscosmos said it lost contact with the spacecraft at 11.57 GMT on Saturday after it reported a glitch while going into its pre-landing orbit. "During the operation, an abnormal situation occurred on board the automatic station, which did not allow the manoeuvre to be performed," it said.
"Once Sun sets, there will be no power for the lander and rover to function, and all the equipment will stop working. However, our tests show that there are possibilities of the battery getting recharged upon the next Sunrise. If that happens, we could get another 14 days, or maybe even more," Isro chairman S Somanath said.
Confirming this to TOI, Isro chairman S Somanath said: "It has too much fuel, way beyond our expectations. There's a lot of fuel left as everything was very nominal on the way to the Moon and there were no contingencies requiring corrections (for which fuel would have been expended). We're left with almost all the margin, that's around 150+kg."
Russia's Luna-25 mission has entered the Moon's orbit and is set to make a soft landing on the south pole on Monday; days before India's Chandrayaan-3. Luna-25 will circle the moon for five days before its landing. The landing site is close to where Chandrayaan-3 was expected to land.
Dust particles from river deltas can more potently influence ice formation in clouds than those from deserts, researchers have found. At low temperatures, atmospheric dust particles are known to enable the aggregation of ice particles to form ice crystals in clouds. In the absence of dust, called ice-nucleating particles, water in clouds can remain in liquid form despite freezing temperatures.
Former chairman of Atomic Energy Commission Rajagopala Chidambaram, who played a key role in India’s first nuclear test at Pokhran in May 1998, has scathing words for the US for the shabby treatment and humiliation of Robert Oppenheimer, the father of the atomic bomb.
With the journey so far having gone exactly as planned, Chandrayaan-3, whose orbit circularisation phase began with the completion of the lunar-bound manoeuvre on August 14, is expected to enter a 100km circular orbit after another operation planned for 8.30am on Wednesday (August 16).
The Aditya-L1 spacecraft will study a number of properties of Sun, such as the dynamics and origins of coronal mass ejections and its home — L1 or the first Lagrange point of the Earth-Sun system — will allow it to orbit Sun at an almost constant distance from Earth, but without the planet ever eclipsing its view of our star.

Utilizing the James Webb Space Telescope, astronomers have successfully gazed upon Earendel, marking the most remote star ever identified. Although initial estimations placed Earendel's distance from our planet at 12.9 billion light-years, taking into account the universe's expansion and the prolonged voyage of the light, astronomers currently propose that Earendel's current position is situated 28 billion light-years away.
The scientific community has definitely proven that Mars had habitable surface environments early in its existence. Water, energy sources, elements such as carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, as well as crucial catalytic transition metals linked to life as we know it were all produced by these conditions. It is unknown, though, if that possibility sparked continued development towards the independent emergence of life on Mars.
The EG.5 strain of the SARS-CoV-2 virus has been designated by the World Health Organization (WHO) as a "variant of interest," although it is not considered to pose a greater risk to public health than other strains. The variant was originally identified on February 17 and was categorized as a variant under monitoring in July. EG.5 is a descendant of the Omicron subvariant and bears an additional mutation in the spike protein.
