Heatstroke is the most serious heat-related illness that can become fatal if you do not receive immediate treatment. It is important to recognize what can cause this condition,learn the signs and symptoms and know when to seek professional help and take preventive measures. Types of heatstroke

A heatstroke occurs when you’re exposed to extremely hot conditions and your body overheats, isn’t able to cool down and fails to control or regulate your body temperature properly. This is referred to as the “classic” heatstroke.

“Exertional” heatstroke happens when you perform intense or vigorous physical activity and your body overheats during exercise.

Heat exhaustion, on the other hand, is your body’s response to excessive loss of water and salt usually through excessive sweating. This condition is most likely to affect people with high blood pressure, the elderly, and those working in hot environments. Signs and symptoms

To help you or someone else get the proper assistance and support they need to save their life, be on the lookout for the following signs and symptoms: A rapid pulse (a heart rate of about 100 beats per minute or higher) Confusion or disorientation Decreased urine output Elevated body temperature (a body temperature of 103 degrees Fahrenheit or higher) in a matter of minutes Excessive sweating Fatigue Feeling dizzy or lightheaded Heavy breathing Hot and dry skin that appears flushed or red Low blood pressure Loss of consciousness (fainting) Nausea or vomiting Pounding headache Thirst Weakness

Keep in mind that these symptoms can vary depending on the type of heatstroke you have.

With classic heatstroke, the skin may appear more hot and dry, while exertional heatstroke can cause prolonged and excessive sweating after exercise stops.

It is essential to seek out medical care as soon as possible if you experience heatstroke symptoms or notice someone else that may be displaying signs of a heatstroke. Risk factors

Factors that can make you more vulnerable to developing heat-related illnesses, such as heatstroke, include: Consuming excess alcohol, which can lead to dehydration Not drinking enough water Having a history of previous heat illness Taking prescription medications that affect the body’s ability to retain water or respond to heat First aid

If you suspect heatstroke, call 911 or your local emergency number.

If you’re the first responder to someone having a heatstroke, your primary goals are to move the person out of the heat right away and stabilize his/her vital signs like body temperature, pulse or heart rate, and breathing or respiratory rate.

Cool the person by whatever means available. Remove excess clothing to maximize heat loss from the body. (Related: How to stay cool if you lose power during a heatwave.)

If the person is conscious, offer chilled water, a sports drink containing electrolytes or other nonalcoholic beverages without caffeine.

You may also fan the person while sponging or spraying him/her with cool water; place ice packs or cool wet towels on the neck, armpits, groin and back to help the body cool down quicker; and cover the person with cool damp sheets.

Begin CPR (cardiopulmonary resuscitation) if the person loses consciousness and shows no signs of circulation, such as breathing, coughing or movement. Wait for the Emergency Medical Team (EMT).

Depending on the severity of the condition, the healthcare provider may also recommend the following techniques when you or a heatstroke patient are at the hospital: Hooking up to an intravenous (IV) infusion to help give the body the fluids it needs Taking an ice bath Using a cooling blanket How to prevent heatstroke

Here are some tips and measures to take that may help prevent heatstroke especially during hotter seasons or when engaging in physical activity: Pace yourself and plan your schedule accordingly if you have any intense activities or chores planned for the day. Keep out of the sun during the hottest parts of the day (between 11 am to 3 pm). Stay indoors with fans or air conditioning or in a cool shaded area. Drink lots of water even if you dont feel thirsty. Staying hydrated will not only help you feel better but it will help your body work more efficiently. (Related: Drinking more water essential to improved mood, increased energy.) Eat more potassium-rich foods and those with high water content they have a natural cooling effect on the body. Strip down and adjust your attire so that you arent wearing stifling, restrictive clothing all day. Ditch any tight-fitting shirts and jeans and stick to more breathable fabrics that are loose-fitting and ideally light in color. Cotton or linen will work well. The right clothes will keep you much cooler. Think twice before you open all the windows of your house to keep cool if the temperature is higher outside than inside, you might lose a possible cool haven. Close the curtains, or blinds, in rooms where they face the sun instead. Take frequent cold showers, or a swim, to cool down quickly. Survivingheatstroke

Your prognosis (or outlook) for heatstroke will depend on a variety of factors, including your age, underlying conditions, how high your temperature rose, and how quickly you sought treatment from a healthcare provider.

As a rule of thumb, taking preventative measures on hot days and removing yourself from hot conditions as soon as possible can improve your chance of survival. The longer you wait without receiving care, the more serious your condition can become.

It’s important to note that once you recover from heatstroke, you should take a rest and avoid physical activity and hot conditions for at least one week.

Once you experience heatstroke, you are also at an increased risk of experiencing another heat-related illness. That said, have regular check-ups and take precautionary measures to reduce your risk.

El Capitan Is Now the Fastest Supercomputer on the Planet

The world’s most powerful supercomputer, El Capitan, has been officially launched at the Lawrence Livermore National Laboratory (LLNL) in California. Built at a cost of $600 million, the system has been designed to manage highly classified national security tasks. The primary objective of the supercomputer is to ensure the security and reliability of the U.S. nuclear stockpile in the absence of underground testing, which has been prohibited since 1992. Research in high-energy-density physics, material discovery, nuclear data analysis, and weapons design will be conducted, along with other classified operations.

Performance and Capabilities

According to reports, El Capitan became the fastest supercomputer globally after achieving 1.742 exaFLOPS in the High-Performance Linpack (HPL) benchmark. The system has a peak performance of 2.746 exaFLOPS, making it the third machine ever to reach exascale computing speeds. The measurement, taken in floating-point operations per second (FLOPS), represents the ability of the supercomputer to perform one quintillion (10^18) calculations per second.

As reported by space.com, the second-fastest supercomputer, Frontier, located at Oak Ridge National Laboratory in Illinois, has recorded a standard performance of 1.353 exaFLOPS, with a peak of 2.056 exaFLOPS. El Capitan’s significant advancement marks a leap in computational capabilities within high-performance computing.

Technical Specifications

As reported by The Next Platform, El Capitan is powered by over 11 million processing and graphics cores distributed across 44,544 AMD MI300A accelerated processing units. These units incorporate AMD EPYC Genoa CPUs, AMD CDNA3 GPUs, and shared computing memory. Each processing unit includes 128 gigabytes of high-bandwidth memory, designed to optimise computational efficiency while minimising power consumption.

Development and Commissioning

Reports indicate that construction of El Capitan began in May 2023, with the system going online in November 2024. The official dedication took place on January 9, 2025. The supercomputer was commissioned by the U.S. Department of Energy’s CORAL-2 program as a successor to the Sierra supercomputer, which was deployed in 2018 and currently ranks 14th in the latest Top500 list of most powerful supercomputers.

With El Capitan’s full-scale deployment, advancements in national security research and computational science are expected to reach unprecedented levels.

Bank of England rate-setter sees no repeat of extended inflation spike ahead

Bank of England rate-setter sees no repeat of extended inflation spike ahead

A member of the Bank of England’s rate-setting committee has made a case for a steeper cut to interest rates on expectations that an inflation “hump” ahead will be temporary.

Catherine Mann, an American economist, told an audience in Leeds that she currently did not see a repeat of an extended period of inflation in the months to come, such as that which followed Russia’s invasion of Ukraine.

She described herself as an “activist” on the Bank’s monetary policy committee, having voted last week for a half percentage point interest rate reduction.

Ms Mann said her decision aimed to “cut through the noise” about the right stance for policy given the weaker outlook for employment and the economy than had been previously expected at the end of 2024.

But she cautioned that while her policy path differed to the majority view for “gradual” rate reductions, the Bank rate, she said, would need to remain restrictive for longer.

Ms Mann had been considered the top hawk – a policymaker leaning towards higher rates – on the Bank’s monetary policy committee (MPC) until it emerged she had backed a half-point cut.

A 0.25 percentage point reduction was passed.

Her earlier worries about rate cuts included a high pace for wage growth and budget-linked investment, stoking inflation down the line.

Last Thursday’s rate decision meeting minutes showed that she, and one other member of the MPC Swati Dhingra, had varied concerns relating to the Bank rate remaining too restrictive at a time of weak economic growth and a weakening employment outlook, with both likely to weigh on inflation naturally.

New Bank staff projections saw the economy growing by just 0.75% this year and inflation topping 3.7% – up from the current 2.5% rate.

Ms Mann told the audience at Leeds Beckett University: “In a speech last February I said, ‘Do not be seduced by the deceleration in headline inflation’. This February, I say, ‘Do not be dismayed by the hump… yet’.”

She expected much of the anticipated increase in inflation this year to come from energy and food, with contributions from other elements such as water bills, phone bills and insurance.

These are factors outside the Bank’s control.

What it wants to avoid is a price spike that forces up wage growth to counter the higher costs – as happened after the energy-led start to the cost of living crisis in 2022.

She said that elements such as budget tax rises on employment would, as Bank surveys have suggested, weigh on both wage growth and therefore inflation.

“I chose 50 basis points now, along with continued restrictiveness in the future, and a higher long-term Bank Rate
to ‘cut through the noise’,” she added.

Affirm, the online lender founded by Max Levchin, expanded beyond credit and entered the debit market four years ago with a card that let users pay over time. Now the company is making it possible for banks to offer that service to their customers.

Affirm, which pioneered the buy now, pay later business (BNPL), has partnered with FIS in a deal that will allow the fintech company to offer the pay-over-time service to its banking clients and their millions of individual customers.

Any bank that partners with FIS will be able to provide its own version of the Affirm Card, which launched in 2021, without asking customers to adopt a new piece of plastic. Consumers can access Affirm’s biweekly and monthly installment plans and have the money automatically deducted from their checking account.

There are approximately 230 million debit card users in the U.S., according to the Federal Reserve Bank of Atlanta. BNPL services have traditionally been tied to credit cards or standalone financing products, rather than to debit offerings.

Affirm CEO on earnings: Consumer is thriving and shopping across the board

“Consumers today are looking for innovative and user-friendly experiences that give them flexibility and control over their money,” Jim Johnson, co-president of banking solutions at FIS, said in the press release. Affirm’s offering can help banks “offer more competitive, differentiated services through their own banking channels,” he said.

Affirm has over 335,000 merchants in its network, ranging from travel booking sites and concert ticket providers to jewelry stores and electronics providers. By bringing BNPL into the debit world, Affirm aims to provide consumers more alternatives to credit.

In its earnings report last week, Affirm reported better-than-expected quarterly revenue and posted a surprise profit from the holiday period. The stock rocketed 22% after the announcement.

Affirm’s active consumer base grew 23% year over year to 21 million users. The Affirm Card now has 1.7 million active users, up more than 136% from the year-ago quarter. Card volume has more than doubled.

In June, Affirm and Apple announced plans for U.S. Apple Pay users on iPhones and iPads to be able to apply for loans directly through Affirm.
