A new study has found that a combination of two drugs could enhance the immune system to treat one of the most common types of cancer in the world, bowel cancer. Also known as colorectal cancer, despite its widespread presence, the treatment options for this condition are limited. What the study specifically found was that this procedure could shrink the tumours caused by this condition by around 60%.

What Are The Drugs Involved

The trial involved the use of two immunotherapy drugs, botancilimab and balstilumab. It is a monoclonal antibody that works to stimulate the body's immune system to attack cancer. The study is a rather significant find, as it’s the first time that a consistent and durable response to immunotherapy has been reported in patients with solid MSS mCRC tumours.

The study was divided into several phases for more than 6 months. In the US trial, around around 101 patients with microsatile stable metastatic colorectal (MSS-mCRC) tumours showed a decrease . Around 61% of the patients experienced tumour shrinkage or stabilization after combined treatment with votancilumab and balstilumab. When it comes to downsides, diarrhea and fatigue were found to be the most common side effects or side effects of this drug.

These results are interesting and open to exploration. To date, immunotherapy has not been effective in patients with CNS-mCRC tumors. This study demonstrates the potential of the combination of botenlimab and balstilimab in the treatment of CNS mCRC, providing new hope for people diagnosed with colon cancer.

What Could This Mean For Bowel Cancer Treatment In The Future

The study is currently in the final stages of clinical trials, and the US Food and Drug Administration (FDA) hopes to quickly gain approval for its use because of the importance of this area that affects many people. The efficiency shown demonstrates the potential of botansilimab to contribute to broad antitumor immunity.

All in all, the combination of botensilimab and balstilimab represents a promising new direction in the treatment of colorectal cancer. This breakthrough could improve conditions for many patients worldwide and lights a new hope in the fight against this common disease. The results of this study show the effectiveness of immunotherapy in this field and how its potential to transform cancer treatment can only grow in the years to come.

A suspected Ebola case at a hospital in Glasgow, Scotland, has been ruled out after the patient tested negative for the virus, health officials confirmed.

The patient was admitted to the Queen Elizabeth University Hospital (QEUH) in the early hours of June 30.

The precautionary response had prompted heightened infection control measures and an assessment by specialist teams, but authorities said there is no confirmed case of Ebola and no risk to the wider public based on current findings.

"The test result has now been received and is negative," said a spokesperson from the Public Health Scotland (PHS).

If confirmed, it would have been the first case in the UK since an outbreak in the Democratic Republic of Congo and Uganda in May.

The PHS noted it has established protocols including contact tracing, clinical assessment and precautionary testing for assessing and testing travelers arriving in the UK from areas affected by Ebola.

The number of confirmed Ebola cases in the Democratic Republic of Congo has increased to 1,333, including 399 deaths, government data showed on Tuesday (June 30, 2026).

The confirmed cases have been recorded from three provinces – Ituri, North Kivu and South Kivu.

The virus has now also reached Haut-Uele province, which borders South Sudan and the Central African Republic, according to AFP.

Haut-Uele province is home to around 15 million people. Health officials said the first case in Haut-Uele was detected after an infected person travelled from Bunia, the capital of Ituri. The patient later died, according to sources at the National Institute of Biomedical Research (INRB).

The outbreak in Africa was declared a public health emergency of international concern by the World Health Organization (WHO) in May. So far, the deadly disease has been limited to Congo and Uganda. A case of Ebola was reported in France in a doctor who contracted the virus while on a humanitarian mission in Congo.

Meanwhile, the US Centers for Disease Control and Prevention (CDC) has raised its emergency response to the outbreak to Level 1, its highest activation level. The designation, reserved for the most severe public health emergencies, allows the agency to deploy its maximum response capacity.

Despite the escalation, the CDC said the risk of Ebola spreading to the United States remains low.

What Is Ebola?

Ebola is a severe and often fatal viral hemorrhagic fever first identified in 1976. Since then, more than 30 outbreaks have been recorded, primarily in Central and West Africa.

Common Symptoms of Ebola

• Fever
• Headache
• Weakness and fatigue
• Vomiting
• Diarrhea
• Muscle pain
• Sore throat
• Unexplained bleeding or bruising

In severe cases, the disease can lead to organ failure, internal bleeding, shock, and death. Aid organizations warn that without stronger surveillance, expanded testing, faster laboratory turnaround times, and more effective contact tracing, the outbreak could continue to grow in the coming weeks and months.

Unlike flu or Covid, Ebola is not an airborne virus, so it is not spread simply by being near an infected person.

A dangerous heat dome is expected to engulf much of the eastern United States this week, exposing more than 220 million people to extreme heat as Americans prepare for the Fourth of July holiday weekend.

After scorching parts of Europe with record-breaking temperatures, the heatwave is now forecast to bring dangerously high daytime temperatures, oppressive humidity and unusually warm nights across much of the US, according to the National Weather Service (NWS).

"Dangerous, record-breaking heat will intensify across most of the central and eastern U.S. this week. Heat indices will likely exceed 100 degrees. Severe thunderstorms are forecast from parts of the central High Plains into the Upper Midwest, and across parts of the Northeast. Critical fire weather conditions will continue across portions of the Four Corners and Great Basin," the NWS said.

The heat dome is expected to expand across the central and eastern United States, with the most intense heat peaking over the Midwest and Mississippi Valley by Thursday before spreading into the Ohio Valley and the East Coast through the holiday weekend.

Cities including New York City, Philadelphia, Baltimore and Washington, D.C. are forecast to see temperatures climb into the 100s°F (38°C and above).

Forecasters expect more than 100 daily temperature records and about 250 record-warm overnight temperatures through Saturday.

The heatwave will also extend into Canada, particularly southern Ontario and southern Quebec.

According to Environment Canada, millions of Canadians are under yellow and orange heat alerts, with advisories issued across Ontario, Quebec, Alberta, Saskatchewan and the Northwest Territories.

Temperatures in parts of Ontario and Quebec are expected to reach 34°C to 37°C on July 1 and July 2, coinciding with the Canada Day

holiday and the FIFA Club World Cup match in Toronto.

Heat Alerts In Effect

Extreme Heat Warnings have been issued for several major US cities, including:

• Nashville
• St. Louis
• Cincinnati
• Kansas City
• Des Moines
• Chicago
• Detroit

Extreme Heat Watches cover much of the Northeast, where temperatures are expected to exceed 100°F (38°C) through Saturday.

Southern cities including Dallas, Little Rock and Memphis are also expected to face dangerous heat.

Meanwhile, the Four Corners region—covering parts of Utah, Colorado, New Mexico and Arizona—remains under critical fire weather conditions.

How Are Authorities Preparing?

Temperatures between 95°F and 105°F (35°C to 40.6°C), combined with high humidity, are expected to push the heat index to 100°F-115°F (38°C-46°C). Some areas could also break monthly or all-time temperature records.

Authorities have urged residents to limit outdoor activities, stay hydrated and seek air-conditioned spaces or cooling centres.

In New York City, Mayor Zohran Mamdani has activated the city's heat emergency plan, with hundreds of cooling centres opening across the city.

In Detroit, where temperatures could reach 100°F (38°C), officials have opened a dozen air-conditioned recreation centres for residents.

The extreme heat could also affect the FIFA Club World Cup, with some matches expected to exceed the heat-index threshold considered unsafe by the global players' union FIFPRO. Texas is expected to experience the hottest conditions, particularly affecting fans travelling to and from stadiums in Houston and Arlington.

In Canada, the heatwave has prompted officials to establish mobile drinking water stations in parks and extend public swimming pool hours to help residents cope with the extreme temperatures.

How To Stay Safe During Extreme Heat

The US Centers for Disease Control and Prevention (CDC) says extreme heat can affect anyone. Warning signs include muscle cramps, dizziness, heavy sweating, headaches, nausea, weakness and shortness of breath.

To stay safe one must:

• Stay hydrated: Drink plenty of water and avoid excessive caffeine and alcohol.
• Dress for the heat: Wear loose-fitting, light-colored clothing and a wide-brimmed hat.
• Use sunscreen: Apply SPF 30+ before going outdoors.
• Seek cooler spaces: Stay in shaded or air-conditioned areas whenever possible.
• Cool your body: Use wet towels, misting fans or cool water to lower body temperature.
• Recognize heat illness: Seek medical help immediately if symptoms such as confusion, dizziness or nausea worsen.
• Take extra precautions: People with chronic medical conditions or those taking regular medications should consult their doctor on staying safe during extreme heat.

Researchers at a Florida-based university claim that a tiny marine animal found in Antarctica can help scientists develop a new treatment for melanoma, one of the deadliest forms of skin cancer. These marine animals are ascidians, invertebrates known as sea squirts. Belonging to the group of tunicates, they mostly thrive in icy water.

Sea Squirts May Help Treat Melanoma

Certain species of marine animals have proven to be useful in the treatment of various types of cancer. The latest ones are ascidians or sea squirts.

Researchers from the University of South Florida (USF) claim that sea squirts, small tube-shaped marine animals that produce protective chemicals, can help fight an aggressive form of skin cancer called melanoma.

Scientists say that these sea squirts have a bacterium that makes a toxic compound. In the early stages of the study, it was found that this compound is capable of killing melanoma cells without harming healthy cells.

The Study Addresses A Significant Challenge In Cancer Treatment

One of the biggest challenges in cancer treatment is finding drugs that destroy cancer cells while leaving healthy cells unharmed. With this study, scientists say this compound produced by the bacteria inside Antarctic sea squirts can do exactly that, marking a significant milestone in cancer research.

In experiments conducted on mice, it was seen that the compound killed melanoma cells without causing serious harm to the rodents, making it a promising candidate for future drug development.

Even though it shows immense promise, the research is still in its early stages. Before the compound can be tested in people, scientists need to confirm that it is safe and effective in larger animal studies. Clinical trials on humans may still take a while.

There is also a challenge of harvesting large numbers of sea squirts from Antarctica, as it would damage the fragile ecosystem. To avoid that, researchers are now working on creating the compound in the laboratory instead.

Despite encouraging results, it remains an experimental approach, and several years of research and clinical testing will be needed before it can become a trusted and proven therapy for melanoma.

Marine Animals’ Contribution In Cancer Treatment

Ecteinascidia turbinata, a colonial marine invertebrate, commonly called the golden sea squirt, has contributed to the development of Trabectedin, a chemotherapy drug, used to treat soft tissue sarcoma and ovarian cancer.

One of the significant cancer breakthroughs was due to sea sponges. They led to the development of Cytarabine, a chemotherapy medication that has been significant in the treatment of acute myeloid leukemia, acute lymphoblastic leukemia, and certain lymphomas for decades.

Sea cucumbers contain natural substances that can slow the growth and spread of cancer cells. Although research is still in its early stages, the results have been promising.

Researchers also found a powerful anti-cancer compound called dolastatin in sea hares. It inspired targeted cancer drugs that deliver treatment directly to cancer cells while reducing harm to healthy cells.
