Teens who eat more chicken and fish may lower their risk of developing colon cancer, a new study has claimed.
In a study of nearly 20,000 women, those who ate more chicken during their teen years had lower risks of developing colorectal adenomas, which are benign tumours that may progress into colon cancer.
Workers in offices with windows get more and better sleep at night and are more physically active than those in windowless offices, a new study has revealed.
Sleep experts have known that exposure to light helps regulate people’s sleep-wake cycle, or circadian rhythm, and in turn can improve their mood, productivity, alertness and health.
A new research has found that the painkiller codeine is being linked to deaths and serious complications in children.
Researchers found in up to two per cent of children the drug can build up in the liver leading to fatal breathing problems, the Daily Express reported.
So far there have been a total of 76 adverse drug reactions reported, including three deaths.
Codeine is used by GPs and hospital doctors to treat children of all ages but from next month doctors will be told only to use it in children over 12.
A new type of intervention program through which rural women in India were trained as social health activists to assist women who have HIV/AIDS, has significantly helped improve their life.
The program improved patients’ adherence to antiretroviral therapy and boosted their immune-cell counts and nutrition levels.
The lay women were trained by the research team to serve as accredited social health activists, or ASHA, and their work was overseen by rural nurses and physicians.
A three-dimensional (3D) digital reconstruction of a complete human brain, called the BigBrain, now for the first time shows the brain anatomy in microscopic detail.
It shows the human brain at a spatial resolution of 20 microns, smaller than the size of one fine strand of hair-exceeding that of existing reference brains presently in the public domain.
The new tool is made freely available to the broader scientific community to advance the field of neuroscience.
Researchers from Germany and Canada collaborated on the ultra-high resolution brain model.
Scientists have found that a gene that protects telomeres – the ends of chromosomes – also plays a key role in obesity.
Researchers from the Spanish National Cancer Research Centre (CNIO) are the first to identify a link between telomeres that shorten with ageing and obesity.
“We still don`t know what evolutionary significance to attach to it, but it is at the very least interesting that a telomere gene is related to obesity,” said Maria Blasco, CNIO director and co-author of the study.
Researchers have got an important new insight about how cancer cells are able to avoid the cell death process.
The findings may also suggest a chemotherapeutic approach to prevent the spread of cancers.
According to Zachary T. Schafer, Coleman Assistant Professor of Cancer Biology at Notre Dame, metastasis, the spread of cancer from one organ to other parts of the body, relies on cancer cells ability to evade a cell death process called anoikis.
Metalizing cancer cells are able to survive anoikis, which normally results from detachment from the extracellular matrix.
The water level in the Yamuna has fallen below the danger mark of 204.83 metres in the capital, a government official said Friday. However, those evacuated from the river banks living in relief camps suffer the brunt of the blazing sun, and fear the spread of epidemic.
“The water level of the Yamuna now stands at 204.30 metres, which is below the danger mark of 204.83,” Dharmpal, secretary in Delhi`s revenue and disaster management department said.
The Yamuna river rose to 207.25 metres late Wednesday, the highest since 1978, when it had reached 207.49 metres.
The World Health Organisation (WHO) Friday said there was a dip in the buffers stock of anti-tuberculosis (TB) drugs in India, but this would in no way affect treatment of patients.
“There is a dip in the buffer stock of anti-TB drugs. We understand that the government of India has initiated steps to ensure replenishment,” Nata Menabde, WHO representative to India, said in a statement here.
However, the statement added that “no drugs are out of stock for adult anti-TB patients for both drug sensitive and drug resistant TB”.
Men who cannot produce sperm are more prone to developing cancer than the general population, a new study has revealed.
The study also found that a diagnosis of azoospermia – infertile because of an absence of sperm in their ejaculate – before age 30 carries an eight-fold cancer risk.
Taking iron daily during pregnancy is associated with a significant increase in birth weight and a reduction in risk of low birth weight, a new study has revealed.
The research found that the effects were seen for iron doses up to 66 mg per day.
Researchers in the UK and US analysed the results of over 90 studies- a mix of randomised trials and cohort studies- of prenatal iron use and prenatal anaemia, involving nearly two million women.
Iron use increased a mother`s average haemoglobin levels compared with controls and significantly reduced the risk of anaemia.
Nitrous oxide – best known as laughing gas – has been one of the world`s oldest and most widely used anaesthetics.
However, despite its popularity, experts have questioned its impact on the risk of a heart attack during surgery or soon afterward.
But those fears are unfounded, a new study by researchers at Washington University School of Medicine in St. Louis suggests.
Scientists have discovered the chemical that makes naked mole rats cancer-proof, a finding that could eventually lead to new cancer treatments.
Naked mole rats are small, hairless, subterranean rodents that have never been known to get cancer, despite having a 30-year lifespan.
Researchers led by Andrei Seluanov and Vera Gorbunova from the University of Rochester discovered that these rodents are protected from cancer because their tissues are very rich with high molecular weight hyaluronan (HMW-HA).
A new study by researchers at Queen`s University has determined that adults who accumulated 150 minutes of exercise on a few days of the week were not any less healthy than adults who exercised more frequently throughout the week.
Ian Janssen and his graduate student Janine Clarke studied 2,324 adults from across Canada to determine whether the frequency of physical activity throughout the week is associated with risk factors for diabetes, heart disease and stroke.
An Indian chocolatier, based in London, has brought out chocolates that can contain as little as 20 calories a bar.
Aneesh Popat`s recipe doesn`t have high-calorie ingredients like butter, cream and eggs instead he combines flavour-infused water with cocoa to create The Chocolatier, the Daily Express reported.
The 25-year-old maths graduate`s chocolates have flavours of fizzy cola and strawberry mint to chai tea and apple pie.
His chocolates are already supplied to Michelin star restaurant Apicius in Cranbrook, Kent, and five star hotel Le Meridien in London.

Scientists have developed a new identification mechanism that can detect genetic variations linked to prostate cancer to predict aggressiveness of the disease in a better way, says a study.
The method relies on understanding the genetic interaction between single nucleotide polymorphisms (SNPs). The goal is to better predict a prostate cancer’s aggressiveness to avoid unnecessary radical treatment, say researchers.
The findings of the joint study by researchers at Moffitt Cancer Centre and Louisiana State University of the US was published in the online journal PLOS ONE in April.
Tell-tale sign of cholesterol has been seen in kids as young as three to five, a new study has claimed.
According to experts, childhood obesity builds a ticking time bomb of sickness in later life – and action to avert ill health should start before the kids attain school going age, the Daily Express reported.
Researchers at St Michael’s Hospital in Toronto, Canada, studied the association between diet and non-high-density lipoprotein cholesterol levels in 1,076 pre-school children.
The study has been published in the Canadian Medical Association Journal. (ANI)
Weight loss could result in improved memory in older, overweight women, a new small study has suggested.
Additionally, the study also showed that the women’s brain activity actually changes in the regions of the brain vital for memory tasks after weight loss, the Huffington Post reported.
Lead author Andreas Pettersson, M.D., a Ph.D. student at Umea University in Sweden, said in a statement that their findings suggest that obesity-associated impairments in memory function are reversible, adding incentive for weight loss.
Tiny amounts of silver added to antibiotics could make them 10 to 1,000 times more effective and enable them to fight drug-resistant infections, a new study has claimed.
Scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University found treating bacteria with a silver-containing compound boosted the efficacy of a broad range of widely used antibiotics and helped them stop otherwise lethal infections in mice.
A new study conducted in an animal model at Wake Forest Baptist Medical Center showed that fructose rapidly caused liver damage even without weight gain.
The researchers found that over the six-week study period liver damage more than doubled in the animals fed a high-fructose diet as compared to those in the control group.
“Is a calorie a calorie? Are they all created equal? Based on this study, we would say not,” Kylie Kavanagh, D.V.M., assistant professor of pathology-comparative medicine at Wake Forest Baptist and lead author of the study, said.
Indian recipients prefer to get an organ transplant or blood transfusion from a donor whose personality or behaviour matches theirs, a new study has found.
Some people in India and the US, who undergo transplants, believe that their personality or behaviour may change to become more like that of the blood or organ donor, researchers from the University of Michigan, said.
They feel so “creeped out” that they would decline an organ or blood that came from a murderer or thief, the study conducted on participants from India and US found.
How kids eat their food may turn out to be just as important as what they eat, according to a new study.
The study, led by Dr. Nav Persaud, a family physician, found a significant association between poor eating habits in kids ages three to five and their levels of non-HDL – or “bad” – cholesterol, putting them at risk for cardiovascular disease later in life.
Shedding pounds can not only make you healthier, it may also improve your memory, a new study has claimed.
Memory improves in older, overweight women after they lose weight by dieting, and their brain activity actually changes in the regions of the brain that are important for memory tasks, researchers said.
“Our findings suggest that obesity-associated impairments in memory function are reversible, adding incentive for weight loss,” said lead author Andreas Pettersson, from the Umea University, Sweden.
A long-withstanding puzzle as to how the heart regulates its beat appears to have been solved, paving way for better understanding of heart failure.
When the heart beats (contracts), the contractile machinery is switched on by an increase in calcium within the cell, according to researchers.
This increase is produced by a release from intracellular stores activated by a small influx of calcium into the cell during the cardiac electrical signal – known as the action potential, they said.
A team of scientists has developed a way to see where and how memories are stored in the brain.
The team, led by Don Arnold and Richard Roberts of USC, engineered microscopic probes that light up synapses in a living neuron in real time by attaching fluorescent markers onto synaptic proteins – all without affecting the neuron`s ability to function.
The fluorescent markers allow scientists to see live excitatory and inhibitory synapses for the first time – and, importantly, how they change as new memories are formed.
