Key ingredient for a universal flu vaccine, found in llama blood

Llamas make an array of immune system antibodies so tiny they can fit into crevices on the surface of an invading virus.That feat could one day protect humans from entire families of flu viruses that bedevil scientists with their unpredictable and shape-shifting ways

Key ingredient for a universal flu vaccine, found in llama bloodA universal flu vaccine could finally end this inefficient guessing game. According to the National Institutes of Health, such a vaccine should be 75% effective, protect against group I and group II influenza A viruses (the most common to infect humans), last for at least one year, and be suitable for all age groups. All, […]

Dogs can help sniff out malaria, finds new study

Dogs can detect malaria by sniffing people’s socks. Study says the animals appear able to identify people infected with the disease even if they are not showing symptoms

Dogs can help sniff out malaria, finds new studyDogs possess a sense of smell many times more sensitive than even the most advanced man-made instrument. Just how powerful is a dog’s nose? Powerful enough to detect substances at concentrations of one part per trillion – a single drop of liquid in 20 Olympic-size swimming pools. With training, dogs can sniff out bombs and […]

Noble prize for medicine awarded to immunologists for research on cancer treatment

 This year’s Nobel Prize for Medicine constitutes a landmark in our fight against cancer. The discovery made by the two Medicine Laureates takes advantage of the immune system’s ability to attack cancer cells by releasing the brakes on immune cells

Noble prize for medicine awarded to immunologists for research on cancer treatmentThe Nobel Prize in physiology or medicine has been awarded to James P Allison and Tasuku Honjo “for their discovery of cancer therapy by inhibition of negative immune regulation.” American James P. Allison and Japanese Tasuku Honjo, won the annual award for work on a new approach to cancer treatment Nobel Prize laureate James P. […]

How an electrical implant is helping paralysed people walk again

Three people whose legs were paralysed for years can stand and take steps again thanks to an electrical implant that zaps the injured spinal cord - along with months of intense rehab, researchers reported

How an electrical implant is helping paralysed people walk againTwo separate teams of scientists have revealed for the first time that the technique, together with physical training, has allowed three out of the five people treated to walk again after losing all voluntary movement below the site of an injury. Experts say the device, which is placed below the injury, helps lost signals from […]

Eating a low-carb diet can raise early death risk, cautions study

A low-carb diet could shorten life expectancy by up to four years, a study suggests. The large scale study debunks 'cult of low carb' and shows moderate intake gives best chance of a long life but type of proteins and fats make big difference. Eating a moderate amount of carbohydrates best for healthy lifespan, say researchers

Eating a low-carb diet can raise early death risk, cautions studyLow-carb diets, such as Atkins, have become increasingly popular for weight loss and have shown promise for lowering the risk of some illnesses. But a US study over 25 years indicates that a moderate cut in carb consumption – or switching meat for plant-based protein and fats – is healthier. The study relied on people […]

Dengue fever outbreak halted by release of genetically engineered mosquitoes

The first large-scale deployment of mosquitoes infected with Wolbachia bacteria, which makes them unable to transmit viruses, has stopped all outbreaks of dengue fever in a city in northern Australia for the last four years

Dengue fever outbreak halted by release of genetically engineered mosquitoesInsects unable to transmit viruses halted disease in Australian city – now scientists hope same technique could help tackle Zika and malaria The success of the project in Townsville, Queensland, will encourage hopes that Wolbachia can provide a knockout blow against the Zika virus in Brazil as well, where the mosquitoes have been introduced into […]

Spider venom being utilised to treat rare form of epilepsy

Dravet syndrome is a severe form of epilepsy that typically appears during the first 12 months of life. The condition is resistant to current treatments and, sadly, children who are affected often die before they reach adulthood

Spider venom being utilised to treat rare form of epilepsyAccording to a new study carried out in Australia, a protein found in spider venom could help scientists design an effective medication for the treatment of a rare form of epilepsy. Dravet syndrome ‘is a severe form of epilepsy’ that typically appears during the first 12 months of life. Seizures, which increases in temperature and bright […]

Scientist in Japan to use ‘reprogrammed’ stem cells to fight Parkinson’s disease  

Parkinson’s is caused by a lack of dopamine made by brain cells and researchers have long hoped to use stem cells to restore normal production of the neurotransmitter chemical

Scientist in Japan to use ‘reprogrammed’ stem cells to fight Parkinson’s disease  Japanese scientists said on Monday they will start clinical trials next month on a treatment for Parkinson’s disease, transplanting ‘reprogrammed’ stem cells into brains, seeking a breakthrough in treating the neurodegenerative disorder. The clinical trials come after researchers at Japan’s Kyoto University successfully used human induced pluripotent stem cells (iPS) to restore functioning brain cells […]

New study reveals, nearly 80 per cent of schizophrenia risk down to genes

Psychosocial, environmental, and genetic factors are known to contribute to the risk of developing the disease, but to what extent? New research - carried out by scientists at the University of Copenhagen in Denmark - suggests that almost 80 per cent of the likelihood of having schizophrenia may be genetic

New study reveals, nearly 80 per cent of schizophrenia risk down to genesThe National Institutes of Health (NIH) define schizophrenia as a “chronic, severe, and disabling mental disorder” that affects 1.1 per cent of all adults in the United States. Although the average age of onset for the disease has not been determined, symptoms of schizophrenia usually appear between the ages of 16 and 30. Psychosocial, environmental, […]

Researchers working on blood test to predict premature births

Scientists are trialling a blood test that may predict whether a pregnant woman will give birth prematurely. Preliminary results, published in the journal Science, suggest it is accurate in up to 80% of high-risk women. The team, at Stanford University, in the US, say it is also as accurate as ultra-sound scans at predicting due dates

Researchers working on blood test to predict premature birthsEach year in the U.S., one in 10 babies is born prematurely. Around the world, that number is slightly higher, affecting 15 million infants annually. In a new study published in Science, researchers led by a group at Stanford University report the first steps toward a blood test that can predict which pregnancies are most […]
