Robots might soon be able to ‘smell’ cancer
- Chemicals in patients’ breath, sweat, and tears can point towards cancer.
- All organisms release volatile organic compounds.
- Robots being able to smell diseases is a concept called “volatolomics”.
Detecting diseases might become easier in the future with robots’ ability to “sniff” hidden illnesses, surprisingly including cancer, by smelling a person’s breath.
Scientists are trying to find out techniques that can analyse chemical compounds in patients’ breath, sweat, and even tears and point towards diseases. Experts believe these chemicals are like “fingerprints” leading to diagnosis.
Researchers call the concept “volatolomics” and make it clear that the robot will not be commercially available at any time.
Whenever we smell anything, the nose encounters volatile organic compounds, which evaporate very quickly and have a low boiling point. These are the products of human metabolism that can be excreted out in some form.
All organisms release VOCs for various purposes like communication, reproduction, and even defense. Similarly, the body releases VOCs as a response to biological changes as well like falling sick.
Electronic noses (e-noses) have been found to have a high level of diagnostic accuracy for the detection of cancer in exhaled breath according to a systematic review and meta-analysis by a group of Dutch researchers.
A combination of gas-chromatography and mass spectrometry (GC-MS) can study exhaled breath samples.
A study, for example, suggested that ovarian cancer has certain markers.
In the review article on Hospital Healthcare Europe, 52 publications that included more than 3,000 cancer patients (including lung, gastric, breast, and prostate) were included in the analysis .
While volatolomics is a relatively new concept, scientists report that the idea has existed for centuries. Back then, however, scientists did not have the technology to experiment.
With machine learning and artificial intelligence, scientists can put their knowledge to use. Nanomaterial sensors, for example, can accurately recognise VOC fingerprints coming from food, beverages, pollution, and people.
The findings appeared in the journal Nano Research and Hospital Healthcare Europe.

Massive power breakdown hits Pakistan
- Minister says power generation units are temporarily shut in winter at night.
- Says frequency variation in national grid triggered outage.
- Says ministry trying to restore power in next 12 hours.
LAHORE/KARACHI/QUETTA/ISLAMABAD: A countrywide power breakdown, triggered by a “frequency variation” in the national grid early Monday morning, has left large parts of the country including Karachi, Lahore, Islamabad, Peshawar and Quetta without electricity.
Power Minister Khurrum Dastagir, while talking to Geo News, said that the power generation units are temporarily shut down in winter at night as an economic measure to save fuel costs.
“When the systems were turned on at 7:30am this morning one by one, frequency variation was reported in the southern part of the country between Jamshoro and Dadu. There was a fluctuation in voltage and power generating units were shut down one by one due to cascading impact. This is not a major crisis,” said the federal minister as the country plunged into darkness for the second time in four months.
The minister said that his ministry has started restoring some grid stations in Tarbela and Warsak.
“Peshawar Electric Supply Company (PESCO) and some grids of Islamabad Electric Supply Company (IESCO) have already been restored,” claimed the minister.
Talking about the breakdown in Karachi, the minister said that the matter in the port city is complicated as it has a complete electric supply system.
“We provide K-Electric about 1,000-1,100 megawatts routinely, however, it will be restored within a few hours. It is not certain how long will it take to sort this issue. However, my target is to restore electricity in the country in the next 12 hours,” said the minister.
Before the energy ministry’s announcement, different power distribution companies had confirmed the breakdown.
According to Quetta Electric Supply Company (QESCO), the two transmission lines have tripped leaving 22 districts of Balochistan, including Quetta without power.
Karachi power update
Meanwhile, K-Electric spokesperson Imran Rana said that at approximately 7:34am today, the national grid experienced a loss of frequency, affecting the power supply to multiple cities across Pakistan
“This has also cascaded to KE’s network affecting power supply to Karachi,” Rana said, adding the KE’s network is safe and protected.
“Our teams are actively monitoring the situation and enabling restoration efforts.”
An IESCO spokesperson said that its 117 grid stations were without electricity.
Meanwhile, PESCO also confirmed the outage in areas where it supplies electricity.
This is the second time within four months that a country was hit by a major power breakdown.
NEPRA takes notice
The National Electric Power Regulatory Authority (NEPRA), in a statement, said that it has taken “serious notice” of the power outage and directed the National Transmission & Despatch Company (NTDC) to submit a “detailed report”.
The statement also said that the regulator has previously imposed fines on similar outages in the 2021 and 2022. It also shared that NEPRA has consistently issued directives and recommendations on tackling such events in future.
In October of last year, Karachi, Hyderabad, Sukkur, Quetta, Multan, and Faisalabad were hit by a power outage.
At that time, the power minister said that nearly 8,000 megawatts of power went offline.
Back then, Dastagir had said that the simultaneous faults in two power lines, which had triggered the breakdown, at the same time was concerning for the government. He had also announced that an in-depth inquiry was ordered and promised action.
A timeline of power breakdowns in Pakistan
The country’s generation and distribution network has suffered eight major power breakdowns during the last nine years.
In 2014 and 2017, nationwide blackouts were caused by a fault in Tarbela Power Station while fog, frequency variation and the Guddu Power Plant fault were blamed for breakdowns in 2015, 2018, 2019, 2021, 2022 and 2023.
Every time the party in power announced to conduct a comprehensive probe and vowed to rectify the issues but nothing has happened despite multiple inquiries.
Punjab ordered to issue divorce certificates to non-Muslims
- Lahore High Court directs provincial authority to frame rules within 90 days.
- Petitioner says issue is faced by many members of Christian community.
- NADRA’s Registration Policy allows change of marital status on basis of affidavit.
The Lahore High Court (LHC) Wednesday directed the Punjab government to frame, within 90 days, rules under which union councils would issue divorce certificates to members of Christian and other non-Muslim communities in Pakistan.
In many parts of the country, the divorce certificates are not issued to non-Muslims by union councils that instead claimed such certificates were “not issued to the Christian community.” This is an issue for members of the said community because, without a divorce certificate, they cannot request the National Database and Registration Authority (NADRA) to update their marital status while applying for the renewal of their identity cards.
The matter was brought to the attention of the LHC during the case Shumaila Sharif vs the secretary union council etc.
The petitioner in her appeal requested that the court is a writ of Mandamus — an order from a court to an inferior government official ordering the government official to properly — against the relevant union council and direct it to issue her the divorce certificate.
The case proceedings
The petition was heard on December 16 last year and the presiding judge was Judge Tariq Saleem Sheikh.
During the proceedings, the counsel of the petitioner, Advocate Umar Saeed, said that the issue was faced by several people in the Christian community and was not a one-off incident.
Citing Section 33 (1)(j) of the Punjab Local Government Act 2022 (PLGA 2022) — which mandates that union councils ensure registration of births, deaths, marriages and divorces for all the communities without discrimination — and Article 36 of the Constitution, which expressly requires the state to protect the minorities’ legitimate rights and interests, the counsel argued that by refusing to issue the requisite certificate, the council was failing to fulfil its legal duty.
Additionally, Advocate Kashif Alexander, the court’s amicus curiae on the matter, contended that obtaining a divorce certificate is a legal right that cannot be denied.
Together the two emphasise that while the Constitution of Pakistan (1973) does not explicitly guarantee the right to identity, Article 9 (right to life) and Article 14 (dignity of man) safeguard that right. Therefore, any citizen whose marital status changes due to the dissolution of marriage by divorce has a fundamental right to obtain a divorce certificate from the competent authority and then have their CNIC updated/revised.
The Additional Advocate General has little to defend the respondents and said that the provincial government was taking steps to address the complaints of the Christian community regarding the non-issuance of divorce certificates.
During the proceedings, it was brought to the court’s attention that NADRA’s Registration Policy dated 06.04.2021 (Version 5.0.2) allowed a change of marital status of a divorcee on the basis of an affidavit in the prescribed form.
In light of this, the court directed that until the provincial government framed the requisite rules needed for the issuance of the divorce certificate by the union council, NADRA shall accommodate the Christian community in accordance with the Registration Policy 19.
