When the sun is out after a long winter, every one loves it. But not the people of Canary Islands. Tourists there are being warned about the "unusually high risk" of UV rays this week. The Ministry of Health for this holiday destination has urged both, residents and visitors to take extra precautions and preventative measures to limit the impact of sun exposure over their body and skin.
The Ministry observed Aemet, Spain's national weather agency for the forecast which showed higher than normal UV or ultraviolet radiation levels in the region. It is in this backdrop that everyone in the region are requested to be extra careful when they are out in the sun. UV levels are set to reach 7, which is a 'high risk' in La Palma, El Hierro, La Gomera and Gran Canaria. Other regions like Tenerife, Fuerteventura and Lanzarote are expected to reach a level 6, which is also classed as 'high risk'.
As per the World Health Organization (WHO), a UV index is a measure of the level of UV radiation, which ranges from zero upward. The higher the UVI, the greater potential for damage to skin and eye and the less time it takes for harm to occur, notes WHO.
The range 1 to 2 represents a low risk, 2 to 5 is moderate, 6 to 7 is at high risk, 8 to 10 is at very high and anything over 11 is extremely risky for anyone to stay out.
UV radiation levels fluctuate throughout the day, with the highest values occurring during the four-hour period around solar noon. The reported UV Index (UVI) typically reflects this daily peak. Depending on geographic location and the use of daylight saving time, solar noon falls between 12 p.m. and 2 p.m. In some countries, sun protection advisories are issued when UV levels are expected to reach 3 or higher, as exposure at these levels increases the risk of skin damage, making protective measures essential.
While sun bathing is good, being out in the sun when the UVI indicates a high or very high risk, may cause you health concerns. It can lead to sunburn, premature skin aging, incresed risk of skin cancer, eye damage and in severe cases, heat related disease.
It is one of the most common skin injury which happens when there is excess exposure to UV radiation from the sun. This happens when the UV radiation directly damages the DNA skin cells. These damaged cells die and shed, this is why people experience peeling after getting a sunburn.
This is also a common occurrence when your body loses too many fluids or electrolytes. It can also interfere with your normal body functions. You may feel dehydrated, especially when you are out in the sun, but not well hydrated. The most common symptoms are dizziness, fatigue and headache on hot days.
This is an electrolyte disorder in which your body experiences low sodium in blood. The symptoms could lead to nausea, confusion and even weakness. There are extreme cases when one may have seizures, slip into coma or die.
This is one of the most common consequence of being out under the hot sun. Dehydration with prolonged heat exposure can lead to heat exhaustion.
When you are out under the sun and your body's core temperature cross 104°, heatstroke may occur. This is also known as sunstroke. As per the Centers for Disease Control and Prevention (CDC), it causes more than 600 deaths each year in the United States.

A deadly meningitis outbreak in Kent has claimed two young lives and left several others seriously ill, prompting health authorities to urgently warn students and young people in the area.
According to reports, the outbreak involves invasive meningitis, a severe infection that spreads quickly and can become life threatening within hours. One of the victims was a student at the University of Kent, while the other was a Year 13 pupil from Faversham. Most of the affected individuals are between 18 and 21 years old, and several are university students.
Health officials say at least 11 people from the Canterbury area have been hospitalized and are currently receiving treatment.
The UK Health Security Agency (UKHSA) has begun contacting more than 30,000 students, staff members, and their families to inform them about the outbreak and the precautions being taken.

Government scientists have now confirmed that the outbreak is caused by meningococcal strain B, a type of bacteria that many young people have not been vaccinated against.
Gayatri Amirthalingam, deputy director of immunization and vaccine preventable diseases at the UKHSA, said laboratory testing identified the strain responsible for the cluster of infections.
She explained that teenagers in the UK usually receive a meningococcal vaccine around the age of 13 or 14, but that vaccine protects against strains A, C, W, and Y, not strain B.
This means many teenagers and young adults remain vulnerable unless they received the meningitis B vaccine privately.
The meningitis B vaccine was introduced into the UK’s National Health Service routine immunization schedule for babies in 2015.
As a result, people born before 2015 would not have received the vaccine through the public programme. Some may have chosen to get it privately, but many did not.
Private vaccination can cost between £100 and £120 per dose in the UK, and a full course generally requires two doses.
Experts say this gap in vaccination coverage may partly explain why university-age students are susceptible during outbreaks.
Health authorities are urging anyone who may have been exposed to the infection to take preventive antibiotics immediately. UKHSA has specifically advised people who visited Club Chemistry in Canterbury between 5 and 7 March to come forward for antibiotic treatment as a precaution.
Officials say taking antibiotics quickly can help stop the bacteria from developing into disease and also prevent it from spreading to others. Amirthalingam reassured students that those who have received antibiotics can safely travel home and be around family members.
The disease spreads mainly through close contact, including activities where saliva is shared. Amirthalingam noted that sharing vapes can be one possible route of transmission, although it is not the only one.
Experts say anything that goes into the mouth, including drinks, cigarettes, or vapes, can potentially pass bacteria from one person to another.
Because meningococcal bacteria can live in the throat and nose, close social contact among students often increases the risk during outbreaks.
Meningitis is an infection that causes inflammation of the meninges, the protective membranes surrounding the brain and spinal cord.
The illness is most often caused by bacterial or viral infections, although fungal and other causes are also possible.
Symptoms can include fever, headache, stiff neck, confusion, and sensitivity to light. In severe cases, bacterial meningitis can lead to hearing loss, neurological complications, or death if treatment is delayed.
Doctors stress that early recognition and immediate medical care are critical because the condition can worsen rapidly within a few hours.
"God asks no man whether he will accept life. That is not the choice. You must take it. The only choice is how."
This is what Justice JB Pardiwala said, quoting Henry Ward Beecher to allow India's first ever passive euthanasia for Harish Rana. AIIMS Delhi has now started protocols to implement the Supreme Court verdict for Harish Rana's passive euthanasia. Sources and several reports have mentioned that the process could take two to three weeks.
A specialized team headed by professor and head of the department of anesthesia and palliative medicine, Dr Seema Mishra, has been constituted to implement the process. The team comprises doctors from departments of neurosurgery, onco-anesthesia, and palliative medicine, and psychiatry.
“The process generally involves withholding or withdrawing the nutritional support gradually while ensuring adequate pain relief. The patient is given palliative sedation so that he or she is not in distress. Life support measures such as artificial nutrition, oxygen and medications are slowly withdrawn. The aim is not to prolong nor hasten death,” Dr Sushma Bhatnagar, former head of the department of onco-anaesthesia, pain and palliative care, AIIMS-Delhi.
A video from Rana's home in Ghaziabad showed that relatives were offering prayers and a member of the Brahma Kumaris put a 'tilak' on his forehead. She said, "Sabko maaf karte hue, sabse maafi mange hue, so jaao...theek hai." Which loosely translates to: Forgiving everyone and asking forgiveness from everyone. Now sleep. It's okay.
The Brahma Kumari seen in the video was Sister Lovely from Mohan Nagar Seva Kendra in Ghaziabad. Komal, who is also a member of Brahma Kumaris based in Mount Abu, told this to news agency Press Trust of India (PTI). "She is following a ritual with the words that mean he (Harish) leave the world in a happy state, seeking and giving forgiveness...it is part of a meditative chant that comforts the soul and eases the entire process of soul merging with the sublime," she told PTI.
According to Komal, alongside medical consultations, the family also sought spiritual guidance as they prepared for the inevitable after the Supreme Court’s directions.

The Supreme Court of India, in a landmark judgment allowed 32-year-old Harish Rana, who had been living in a vegetative state for last 13 years, the right to die. This means, that the apex court allowed passive euthanasia for Rana. The bench comprising Justice JB Pardiwala an Justice KV Vishwanathan allowed the withdrawal of life support of Rana, who has been in a coma and kept alive on tubes for breathing and nutrition after he sustained severe head injuries following a fall from a building in 2013 in Chandigarh.
The judgment is a win, however, Ashok, Rana's father said that his feelings are mixed. "As a father, this is extremely painful. But on humanitarian grounds, this is the best we can do for my son." He continued, "It is just not a matter of my son, but there are many others in such a state in the country. I think it is the grace of God who guided the Supreme Court judges... I am happy that with this judgments, many others may find a way."

Tech giant Microsoft's new artificial intelligence model GigaTIME will help reduce time and cost as well as expand access to cancer care, said CEO Satya Nadella today.
Nadella noted that its multimodal AI system has shown promise in transforming routine pathology slides into detailed spatial proteomics data -- a high-resolution map of proteins.
The advanced technology may help doctors analyze tumors faster, thus bringing hope to millions of cancer patients worldwide for a better and faster diagnosis.
Taking to social media platform X, Nadella said: “We’ve trained a multimodal AI model to turn routine pathology slides into spatial proteomics, with the potential to reduce time and cost while expanding access to cancer care”.
GigaTIME is a multimodal AI model for translating routinely available hematoxylin and eosin (H&E) pathology slides to virtual multiplex immunofluorescence (mIF) images.
H&E is the "gold standard" technique in pathology for diagnosing cancer. The mIF images share details of proteins and their locations in cancer cells, thus advancing precision immuno-oncology research.
Developed in collaboration with Providence and the University of Washington, the team trained GigaTIME on a dataset of 40 million cells with paired H&E and mIF images across 21 protein channels.
The multimodal AI, which analyzed standard pathology slides, showed the potential to generate a “virtual population” of tumor cells. It also revealed the detailed protein activity within cancer cells.
The images also offer deeper insights into how tumors behave and disease progression, enabling doctors to cut down the time and cost of diagnosis.
“GigaTIME is about unlocking insights that were previously out of reach,” explained Carlo Bifulco, chief medical officer of Providence Genomics and medical director of cancer genomics and precision oncology at the Providence Cancer Institute, in a Microsoft Blogpost
“By analyzing the tumor microenvironment of thousands of patients, GigaTIME has the potential to accelerate discoveries that will shape the future of precision oncology and improve patient outcomes,” Bifulco added.
In the paper, detailed in the journal Cell, scientists from Microsoft reported that they applied GigaTIME to 14,256 cancer patients from 51 hospitals and over a thousand clinics.
The AI system generated a virtual population of around 300,000 mIF images spanning 24 cancer types and 306 cancer subtypes.
This virtual population uncovered 1,234 statistically significant associations linking mIF protein activations with key clinical attributes such as biomarkers, staging, and patient survival.
"By translating readily available H&E pathology slides into high-resolution virtual mIF data, GigaTIME provides a novel research framework for exploring precision immuno-oncology through population-scale TIME analysis and discovery," the researchers said.
"The GigaTIME model is publicly available to help accelerate clinical research in precision oncology," they added.
