India’s wealthy haul at maths olympiad
The six-member Indian staff that took half within the sixty fifth version of the Worldwide Mathematical Olympiad (IMO 2024) held in Tub, UK, from July 11 to 22 received 4 gold medals, one silver, and one honourable point out. The staff rank was fourth out of 108 taking part international locations. The staff comprised Adhitya Mangudy Venkata Ganesh (Pune), Ananda Bhaduri (Guwahati), Kanav Talwar (Noida, Uttar Pradesh), and Rushil Mathur (Mumbai), all of whom received gold; Arjun Gupta (Delhi), who received silver; and Siddharth Choppara (Pune), who received an honourable point out.
That is the most effective efficiency within the IMO by an Indian staff because the nation’s debut within the competitors in 1989, when it comes to the variety of gold medals received and the rank achieved, a press launch by the Homi Bhabha Centre for Science Training (HBCSE) of the Tata Institute of Elementary Analysis, Mumbai, mentioned.
The IMO, which was began in 1959, is the World Championship Arithmetic Competitors for highschool college students and is held yearly in a unique nation. Collaborating international locations ship at most six college students to the IMO annually. Indian participation is coordinated by the HBCSE.
IMO 2024 had six questions of seven marks every. Google’s specialised AI techniques, AlphaProof and AlphaGeometry 2, developed at its subsidiary DeepMind, labored collectively to efficiently remedy 4 out of the six issues, which is equal to successful the silver medal. The highest 4 international locations and their scores are given within the tableYoungs. In all 609 college students took half (528 boys, 81 ladies).

A blood check to detect most cancers
Roger Zemp and colleagues of the College of Alberta, Canada, have developed a non-invasive and painless cancer-detection methodology utilizing ultrasound waves as an alternative of the same old biopsy for tissue extraction to acquire genetic details about a affected person’s most cancers. The tactic additionally allows early detection of sure kinds of most cancers. Zemp reported this improvement by his staff on the latest assembly of the Acoustical Society of America in Ottawa, Canada.
Data about genetic mutations or chromosomal abnormalities within the cells of a rising tumour is crucial for an correct prognosis of the most cancers and for prognosis and remedy. Zemp’s staff used ultrasound pulses to stimulate most cancers cells to launch their genetic data. This data then circulates within the bloodstream and will be detected by way of a blood check. That is much less painful, considerably cheaper, and simpler to carry out than a conventional biopsy.
By rising cancerous human tumours in mice, the staff discovered that this methodology additionally elevated the focus of cancer-relevant DNA and RNA biomarkers within the bloodstream by as much as an element of 100, which was enough for detection with a blood check. “Individuals have been in search of methods to make use of blood checks to make diagnoses for fairly a while, however it’s difficult as a result of only a few tumor-specific biomarkers are naturally current within the blood,” Zemp was quoted by the American Bodily Society’s on-line journal Physics.

Curiosity finds elemental sulphur on Mars
ON Could 30, Curiosity, NASA’s Mars rover, drove over a rock and cracked it open to disclose one thing by no means seen earlier than on the purple planet: elemental yellow sulphur crystals.
Since October 2023, the rover has been exploring a area of Mars wealthy with sulphates, compounds containing sulphur and oxygen that kind as water evaporates. In contrast to the previous findings, which have been of such sulphur-based minerals product of sulphur and different supplies, the newest detection is of pure elemental sulphur. NASA scientists usually are not clear about what relationship, if any, the fundamental sulphur has to the opposite sulphur-based minerals within the space.
In contrast to sulphur compounds that odor of rotten eggs arising from hydrogen sulphide fuel, elemental sulphur is odourless. It types solely in a slender vary of situations that scientists had not related to the historical past of this location. And Curiosity has discovered numerous it: a whole area of vibrant rocks just like the one the rover crushed. “Discovering a discipline of stones product of pure sulphur is like discovering an oasis within the desert,” mentioned Ashwin Vasavada, Curiosity’s mission scientist of NASA’s Jet Propulsion Laboratory. “It shouldn’t be there, so now we now have to elucidate it.”
It is without doubt one of the a number of discoveries Curiosity has made whereas roving over the rocky Martian terrain inside Gediz Vallis channel, a groove that winds down on the 5-km-tall Mount Sharp, the bottom of which the rover has been ascending since 2014. Every layer of the mountain represents a unique interval of Martian historical past. Curiosity’s mission is to check the place and when the planet’s historic terrain might have supplied the vitamins wanted for microbial life, if any ever shaped on Mars.
Whereas the sulphur rocks had been too small and brittle to be sampled with a drill on the discovery website, a big rock nicknamed “Mammoth Lakes” that was secure for drilling with the rover’s highly effective drill on the finish of the six-wheeled rover’s 2 m robotic arm was situated shut by. Curiosity pocketed the powderised rock into devices inside it for additional evaluation.
