An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.
One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.
Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.
The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.
The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.
Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”
The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.
Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.
The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.
Malaria Alert in Germany: Frankfurt Airport Worker Dies After Suspected ‘Mosquito Arrives on Plane’; 5 Infected
In an unusual case, an employee at Germany’s Frankfurt Airport has died from malaria, while five others have contracted the potentially serious infection after mosquitoes suspected of arriving on an aircraft were found at the airport.
The airport operator, Fraport, confirmed the employee’s death and said the five other infected people are receiving medical treatment.
Authorities have installed mosquito traps at the airport. Captured mosquitoes will be analysed in laboratories to determine their species and, where possible, establish their origin.
Fraport said its focus is now on information and prevention. Employees have been advised to seek medical attention if they develop malaria-like symptoms and to inform doctors that they work at the airport.
“Sadly, we must confirm that one employee has died as a result of the infection,” a Fraport spokesperson told the BBC.
The company said it had provided information to employees and urged them to consult a doctor if they develop symptoms.
According to Germany's Robert Koch Institute (RKI), four airport employees developed malaria between 4 and 6 July. The institute said mosquitoes were brought to the airport by aircraft from a malaria-endemic region in July.
Malaria transmission within Germany is extremely rare. The RKI says malaria cases in the country almost exclusively occur among people who have travelled to malaria-endemic areas.
The absence of a travel history can make diagnosis more difficult. A delayed diagnosis can increase the risk of severe disease.
The RKI also noted that the last airport-associated malaria case in Germany occurred at Frankfurt Airport in 2023.
Malaria is a potentially life-threatening disease caused by Plasmodium parasites, which are transmitted to humans through the bites of infected female Anopheles mosquitoes.
Common symptoms include fever, chills and headache. More severe malaria can cause confusion, seizures, difficulty breathing and other life-threatening complications.
Symptoms generally begin around 10–15 days after the bite of an infected mosquito, although the timing can vary.
People at increased risk of severe malaria include young children, pregnant women, travellers without immunity and people with HIV/AIDS.
Malaria is not normally transmitted directly from person to person. However, transmission can occur through infected blood, including in rare circumstances through blood transfusion or contaminated needles.
According to the World Health Organization's World Malaria Report 2025, an estimated 282 million malaria cases and 610,000 deaths occurred worldwide in 2024 across 80 malaria-endemic countries.
The WHO African Region accounted for approximately 94% of global malaria cases and 95% of malaria deaths in 2024.
WHO estimates that malaria-prevention tools, including recommended vaccines and other interventions, helped avert approximately 170 million cases and 1 million deaths in 2024.
The report noted that WHO approved the world’s first malaria vaccines in 2021, and 24 countries have now added them to their regular immunisation schedules.
Despite the setbacks, there have been encouraging developments. So far, 47 countries and one territory have received malaria-free certification from WHO. Cabo Verde and Egypt were declared malaria-free in 2024, followed by Georgia, Suriname, and Timor-Leste in 2025.

COVID-19 is rising across the US again. Doctors have been reporting an increase in patients testing positive through the summer. But some physicians are noticing a change in how the illness is presenting.
Reports have emerged stating that COVID is resurfacing with new symptoms including nausea, vomiting and diarrhoea.
The CDC's latest respiratory illness data, updated August 21, shows that national and regional COVID-19 activity is increasing, although overall acute respiratory illness causing people to seek healthcare remains very low. COVID-19-related visits to the emergency room are also increasing.
Recent reports from doctors in Georgia describe patients arriving with gastrointestinal symptoms alongside, or sometimes instead of, the more familiar respiratory symptoms.
Although these symptoms may seem unusual compared with the classic COVID presentation, nausea, vomiting and diarrhoea are not new symptoms of COVID-19.
The CDC has included nausea, vomiting and diarrhoea among the possible symptoms of COVID-19 for years. What appears to be attracting attention now is that some doctors are seeing more patients presenting with these gastrointestinal symptoms during the current summer rise.
Dr James Black, medical director of emergency services at Phoebe Putney Memorial Hospital in Albany, Georgia, said doctors are still seeing fever, cough and upper-respiratory symptoms, but added, “A lot of people are coming in with gastrointestinal symptoms - nausea, vomiting, diarrhea, sometimes to the point of mild dehydration.”

The digestive system contains ACE2 receptors, which the virus can use to enter cells. Infection and the body's inflammatory response can therefore contribute to symptoms like nausea, vomiting and diarrhoea.
Gastrointestinal symptoms can occur with respiratory symptoms or sometimes before them, which can make COVID harder to distinguish from stomach infections or food poisoning. That is why doctors say testing remains essential, especially when COVID is active in a certain area.

If nausea, vomiting or diarrhoea occur alongside fever, cough, sore throat, congestion, fatigue or body aches, COVID should be considered, particularly when infections are increasing in the community. Testing can be especially important for people at higher risk of severe disease because antiviral treatment works best when started early.
Dr Gurinder Singh Sidhu, US antiviral medical lead and senior director at Pfizer, said, "People at higher risk should seek medical advice promptly rather than waiting for symptoms to become severe."
Severe vomiting or diarrhoea can also cause dehydration, so people should seek medical care if they cannot keep fluids down, are becoming unusually weak or dizzy, are urinating much less than usual, or develop breathing difficulties.

What if an old plastic bottle could become part of your next snack? Scientists at Southern Illinois University Carbondale have created a process that converts plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies.
The unusual food, called µBites, is being developed as part of NASA’s project to explore ways to produce food in environments where there are limited resources like long deep-space missions.
The researchers say that the technology could also have applications in disaster-afflicted zones and areas where there are acute food shortages.
The process starts with polyethylene terephthalate (PET), the type of plastic commonly used to make water and soft-drink bottles.
Researchers first break down PET, along with discarded corn stalks and leaves, using a process called oxidative hydrothermal dissolution.
It uses water and oxygen at high temperatures and pressures to turn the tough waste materials into smaller molecules that microbes can use.
The researchers then use specially programmed yeast as tiny biological factories. The yeast converts compounds derived from the waste into proteins, fats, acids, vitamins and flavouring molecules.
The resulting mixture is mixed with ingredients like fibre, starch and sweetener before being moulded into cookies using a 3D printer.

Associate Professor Lahiru Jayakody, who leads the project, said the team was initially looking for ways to turn plastic waste into more valuable products. “Why not focus on making food? Because plastic is carbon and food is carbon,” Jayakody said.
He added that the researchers are using microbes to solve problems created by humans. He said, “Microbes are very clever. So, we are using their traits to solve the problems we created.”
The approach could possibly tackle two problems simultaneously — plastic pollution and the need for reliable food sources in environments where conventional agriculture is impossible.

The researchers say their current data show that the µBites are safe to eat, but they have not yet undergone human taste testing. The research team is awaiting approval before conducting human trials.
Preliminary smell evaluations were promising. Most participants said they would be willing to eat the product in an environment where there is no food source. That distinction matters because turning plastic into food ingredients does not mean people are eating plastic itself.
The PET is chemically broken down first, and microbes then use its carbon-containing components to produce new biological molecules.
Long-duration space missions present a particularly difficult food challenge.
Astronauts cannot realistically carry unlimited supplies of fresh food, while growing enough crops in space requires substantial water, energy and equipment.
A system capable of turning waste materials into food ingredients could therefore help reduce the amount of food and raw materials that need to be transported from Earth.
The researchers envision the technology eventually being useful in submarines, disaster-response situations and other isolated environments, in addition to space exploration.
