“I'm not great at the advice. Can I interest you in a sarcastic comment?”

Friends Actor Matthew Perry

This is what ‘Friends’ actor Matthew Perry’s character Chandler Bing was known for. He was known for being funny. However, he had his own struggles in his personal life and those struggles were acute depression. He was treating it with ketamine infusion therapy which is legal in the US and the UK.

What is Ketamine infusion therapy?

Ketamine is an anaesthetic used to treat depression, anxiety and pain under supervised and controlled medical settings. However, it does have its side effects, which can lead to distortion of sight, sound and time. It can also produce calming and relaxing effects.

Ketamine increases a person’s heart rate and blood pressure. If overdosed, it can leave users confused and agitated and can cause them to hurt themselves without even realising it. It can also lead to liver damage and bladder problems.

However, when used in moderation and under the supervision of medical doctors, it can treat depression where traditional antidepressants have failed.

Prof Rupert McShane, a University of Oxford psychiatrist who runs an NHS ketamine treatment clinic told BBC that ketamine “probably turns off the area of the brain that is involved in disappointment.”

Can Ketamine Infusion Therapy Kill Someone?

In simple terms, it cannot, be if the dosage is given in a controlled setting and as prescribed. Ketamine infusion therapy uses drugs in small doses than those used for anaesthesia. It acts faster than traditional anti-depressants, but the effects also wear off way quickly. Which is why it is important to monitor patients’ mental state for relapsing back into depression and discouraging them from overdosing on it.

There are ways of giving people ketamine. One of the ways is through “infusing”, which means to use an IV drip. However, injections, nasal sprays and capsules are also methods used to give people ketamine.

Since the dosage of ketamine used in the infusion treatment is small, it being the reason of actor Perry’s death was ruled out. The medical examiner also noted that Perry’s last ketamine infusion therapy session happened more than a week before his death, which means by the time he had died, it must have worn off.

So, What Happened To Perry?

Though Perry’s last session was more than a week before, his post-mortem showed that his blood contained a high concentration of ketamine. He had died of the “acute effects” of ketamine.

If it was not his session, then how did he get ketamine?

Prosecutors alleged that his assistant gave him at least 27 shots of ketamine in four days before his death, reported BBC.

Perry has been open about his personal struggles and this is what the doctors and dealers used against him. Martin Estrada, the US attorney for California’s Central District told the BBC that people took advantage of his condition. They charged him 165 times more than what vials of ketamine cost.

Names that have come up include Dr Salvador Plasencia, drug dealers “Ketamine Queen” aka Jasveen Sangha and Eric Fleming, and Perry’s live-in assistant Kenneth Iwamasa.

Who Are These Names And What Did They Do?

Ketamine Queen or Sangha supplied drugs that led to Perry’s death. Her home was a “drug-selling emporium,” said Estrada. More than 80 vials of ketamine, and thousands of pills including methamphetamine, cocaine and Xanax were allegedly found in her house known as the “Sangha Stash House.”

Sangha is known to deal with high-end celebs and was a “major source of supply for ketamine to others as well as Perry,” said Estrada.

Dr Plasencia called Perry a “moron” while charging him $2,000 for vials that cost only $12. He sold Perry 20 vials of ketamine between September and October 2023, costing $55,000.

He was the one who taught Iwamasa, who had no medical knowledge to inject the drug. This is after he knew that “Perry’s ketamine addiction was spiralling out of control,” as per what the investigators told the BBC.

Another dealer Fleming was told by Sangha to “delete all our messages.” While Fleming pleaded guilty to conspiring to distribute drugs unlawfully, he also allegedly messaged Sangha: “Please call...Got more info and want to bounce ideas off you. I’m 90% sure everyone is protected. I never dealt with [Perry] only his assistant. So the assistant was the enabler.”

The court documents also revealed that he asked Sangha on whether the ketamine stays in your system or “is it immediately flushed out.”

Dr Pepper, Bots, Cans

The people who allegedly exploited Perry used coded language for ketamine and called it “Dr Pepper”, “bots”, or “cans.”

Selling overpriced drugs, taking advantage of Perry’s mental condition and falsifying medical records to make the drugs given to him look legitimate by Dr Plasencia is what took Perry’s life.

Iwamasa is said to have administered more than 20 shots of ketamine and three on the day Perry died. Whereas ketamine is only administered by a physician. Authorities also found that weeks before Perry’s death, Dr Plasencia allegedly bought 10 vials of ketamine and intended to sell to Perry.

He also injected Perry with a large dose, two days later. This caused him to “freeze up” and spiked his blood pressure.

When I Die, I Want Helping Others To Be The First Thing That’s Mentioned

Perry had always been open about his drug addictions, struggles with alcohol and his depression. He said that his openness would help others who are also struggling and wanted to be remembered by his quote which also is on the homepage of the Mattew Perry Foundation that helps others struggling with the disease of addiction: “When I die, I want helping others to be the first thing that’s mentioned.”

Five arrests have been made in the case so far.

A team of Australian scientists has developed cyborg cockroaches for medical missions. Researchers from the University of Queensland fitted Giant Burrowing Cockroaches with a removable navigation system that enables them to be remotely piloted through complex terrain and rubble.

The cockroaches are equipped with cameras and miniature medical injectors to deliver supervised emergency care to people trapped in collapsed buildings or caves.

What's The Purpose?

Called ‘Paraborgs’, the cyborg insects go beyond searching for survivors to actively assisting them. In the paper, published in Advanced Science, the researchers said the long-term vision is to deploy swarms of specialized cyborg insects at disaster sites, with each performing a complementary role.

“The vision is not to replace first responders, but to give them another way to see, reach and potentially help people when direct access is impossible,” said Dr Vo-Doan from the UQ Biorobotics Lab.

Director of the UNSW Medical Robotics Lab Associate Professor Thanh Nho Do said the Paraborg technology could extend the reach of emergency medicine.

“From a biomedical perspective, the opportunity is to bring treatment to a patient when the patient cannot yet be brought to treatment,” Associate Professor Do said.

“The long-term goal is targeted, human-supervised intervention in places conventional medical technologies cannot access.”

Why Cockroaches?

Dr Vo-Doan said the research demonstrates how cyborg technology can be adapted across different insect platforms.

“Rather than building one robot to do everything, we can harness the natural strengths of different insects and equip them for different missions,” Dr Vo-Doan said.

The larger cockroaches provide greater capacity to carry specialized rescue and medical equipment.

The cockroaches, like the team’s previous cyborg insect models, are anaesthetized during electrode and microchip fitting. They live for as long as other cockroaches once the harnesses are removed.

What About Cyborg Beetles?

The team has previously demonstrated cyborg beetles capable of controlled climbing. They have shown they can remotely guide the movement of common darkling beetles using a video game controller.

The beetles are fitted with removable microchip backpacks that use electrodes to stimulate the insect's antenna or hardened forewings.

The programmable controls allow for precise directional guidance without affecting the lifespan of the beetle.

How Can The Cyborg Cockroaches Aid In Rescue?

Superintendent Tim Hassiotis, Manager Natural Disaster and Humanitarian at Fire and Rescue NSW, said the technology could extend the reach of rescue teams.

“If cyborg insects can safely enter spaces we can’t, locate casualties and ultimately help deliver emergency care, they could become another valuable tool in the future of urban search and rescue,” Superintendent Hassiotis said.

What Could The Future Hold?

Dr Vo-Doan said the longer-term vision was to deploy swarms of specialized cyborg insects, with individuals performing complementary roles.

“Some could carry cameras and environmental sensors, while others could carry specialized emergency or medical equipment,” he said.

“Hopefully, within the next 5 to 10 years, we could see cyborg insect rescue teams deployed to help people in real emergencies, provided we have the resources to accelerate the research and field testing.”

Brain-Eating Amoeba Leaves North Carolina Teen Critically Ill: How Naegleria fowleri Affects?

Updated Aug 28, 2026 | 08:39 PM IST

SummaryNaegleria fowleri is an amoeba naturally present in warm freshwater and can be fatal if water containing the amoeba is forced up the nose and reaches the brain. This can happen during activities such as jumping into water, diving and water-skiing.

A North Carolina teen is reportedly critically ill after being infected with a rare “brain-eating” amoeba called Naegleria fowleri, according to health officials.

The case comes barely a week after an 8-year-old Louisiana girl died after contracting the infection.

North Carolina Teen Critically Ill

The North Carolina Department of Health and Human Services announced on August 27 that a teen resident had been infected with the rare amoeba, which is commonly found in freshwater. The teen is critically ill and receiving medical care.

The department said it is not releasing further information to protect the family’s privacy. The source of the infection is under investigation.

“While these infections are very rare, this is an important reminder that this amoeba is present in our state and across the US,” North Carolina State Epidemiologist Dr. Zack Moore said in a statement.

What Happened To The Louisiana Girl?

Eight-year-old Lillian Smart of Ruston died on August 22, just one day after her eighth birthday. She had been hospitalised since August 15 after developing the infection, which was believed to have been acquired while swimming in Lake Claiborne.

The Louisiana Department of Health confirmed the case on August 19 but did not publicly identify the child.

One of the biggest challenges is the speed at which the infection progresses. According to recent CDC data cited in coverage of the Louisiana case, 173 Naegleria fowleri infections were documented in the US between 1937 and 2025, with only four known survivors. This puts the fatality rate at roughly 97%.

What Is Naegleria fowleri?

Naegleria fowleri is an amoeba naturally present in warm freshwater such as ponds, lakes and rivers. It is not found in salt water or properly maintained and chlorinated pools.

The amoeba does not cause illness if swallowed. However, it can be fatal if water containing the amoeba is forced up the nose and reaches the brain. This can happen during activities such as jumping into water, diving and water-skiing.

Symptoms Of Naegleria fowleri Infection

The infection caused by N. fowleri, also called primary amebic meningoencephalitis (PAM), starts with symptoms including:

  • Severe headache
  • Fever
  • Nausea
  • Vomiting

The infection can then progress to:

  • Stiff neck
  • Seizures
  • Coma
Once symptoms begin, the disease progresses rapidly and usually causes death within about five days. Typically, fewer than 10 people a year in the United States develop PAM.

These rare infections usually occur when it is hot for prolonged periods, leading to higher water temperatures and lower water levels. Naegleria fowleri grows best at higher temperatures, up to 115°F.

How To Stay Safe?

While there is no way to eliminate the amoeba from the environment, some safety measures can reduce the risk:

  • Prevent water from going up your nose by holding your nose shut, using nose clips or keeping your head above water during warm freshwater activities.
  • Avoid putting your head underwater in hot springs and thermal waters.
  • Avoid jumping or diving into warm freshwater during periods of high water temperatures and low water levels.
  • Avoid digging in or stirring up sediment while taking part in water-related activities in shallow.

Norway's King Harald V died on Friday at an Oslo hospital where he was undergoing treatment for a rare blood disorder. He was 89.

“King Harald passed away peacefully at Oslo University Hospital on Friday 28 August, 0635 (local time, 0435 GMT),” the Royal Palace said on its website.

Harald, who was Europe's oldest living monarch, had been hospitalized on August 17. He was initially being treated for complications related to hemolytic anemia — a blood condition in which red blood cells are destroyed faster than the body can replace them. He later developed an infection.

King Harald V’s Health Deteriorated

Harald's condition worsened in recent days after he was admitted to hospital with fluid accumulation in the body linked to a blood disorder. He subsequently developed an infection.

Family members were called to his bedside on Thursday as his condition deteriorated at Oslo University Hospital.

Following his death, the royal flag was flown at half-mast on the palace roof.

Harald had faced several medical setbacks in recent years. He underwent heart surgeries in 2005 and 2020 and was hospitalised multiple times for infections.

What Is Hemolytic Anemia?

According to Johns Hopkins, haemolytic anaemia is a disorder in which red blood cells are destroyed faster than they can be produced. The destruction of red blood cells is known as haemolysis.

Red blood cells normally carry oxygen from the lungs to the rest of the body. When they are destroyed prematurely and faster than the bone marrow can replace them, the number of circulating red blood cells falls.

This can reduce the amount of oxygen delivered to tissues and cause symptoms such as fatigue, weakness and shortness of breath.

What Are The Symptoms Of Hemolytic Anemia?

Symptoms can vary from person to person and may include:

  • Abnormally pale skin
  • Yellowing of the skin and eyes (jaundice)
  • Dark-coloured urine
  • Fever
  • Weakness
  • Dizziness
  • Confusion
  • Reduced ability to tolerate physical activity
  • Enlarged spleen or liver
  • Increased heart rate (tachycardia)
  • Heart murmur

These symptoms can also occur with other blood conditions or health problems. A healthcare professional should be consulted for diagnosis.

How Is Haemolytic Anaemia Diagnosed And Treated?

Diagnosis may involve tests such as:

  • Complete blood count (CBC)
  • Urine test
  • Bone marrow aspiration or biopsy

Treatment depends on the underlying cause and may include:

  • Blood transfusions
  • Corticosteroid medicines
  • Intravenous immune globulin to help regulate the immune system
  • Rituximab

In more severe cases, treatment may include surgery to remove the spleen or immunosuppressive therapy to reduce immune-system activity.

King Harald V’s Family

Harald leaves behind his wife, Queen Sonja, his son and new King Haakon, daughter Princess Märtha Louise and six grandchildren.

Harald V was the first Norwegian-born prince in 567 years.

Following Harald's death, hundreds of people gathered outside the palace in Oslo to lay flowers, while the government declared nationwide mourning until after his funeral.

Harald's 53-year-old son will become Norway's new king, Haakon VIII, while Haakon's 22-year-old daughter Ingrid Alexandra becomes crown princess.
