High levels of microbes deprive host of essential nutrients, research suggests

"Gut bacteria get to use a lot of our food before we do," says Federico Rey, a professor of bacteriology at the University of Wisconsin-Madison. Then we get their leftovers -- or their waste.

Researchers use zebrafish animal model to explore drug-seeking behavior

As the opioid crisis escalates, the science behind addiction remains poorly understood. To address this need, researchers at University of Utah Health devised a system that allowed zebrafish, a small tropical fish, to self-administer doses of hydrocodone, an opioid commonly prescribed to people for pain.

Distinguishing biothreat look-alikes could aid biological surveillance

Biological "detectives" are tracking down biothreats such as the bacteria that causes tularemia ("rabbit fever"), but they constantly face the challenge of avoiding false positives.

Manipulation of single gene defines new pathway to mood disorders

Removing a single gene from the brains of mice and zebrafish causes these animals to become more anxious than normal.

Consumption of EPA and DHA omega-3s reduces cardiac death risk, study shows

Results from a new study published in the Journal of Clinical Lipidology showed that in 14 randomized, controlled trials of 71,899 people, consumption of EPA and DHA omega-3s reduced the risk of cardiac death by a statistically-significant average of 8 percent.

Researchers uncover evidence linking mental health disorders and disturbances to gut microbiome

Better understanding the gastrointestinal microbiome may help psychiatrists treat mental health disorders such as depression, highlights a review in Frontiers in Psychiatry.

Study findings could one day help doctors better predict survival of liver cancer patients

A new study of a molecule that regulates liver-cell metabolism and suppresses liver-cancer development shows that the molecule interacts with thousands of genes in liver cells, and that when levels of the molecule go down, which often happens during liver-cancer development, the activity of certain cancer-promoting genes goes up.

Scientists develop new attract-and-kill technique to eradicate mosquitoes

Mosquitoes aren't just blood thirsty. They also have a sweet tooth, relying on plant nectar to get the sugar they need to survive. Exploiting this weakness, scientists have developed an environmentally friendly eradication method.

Symptoms, triggers of food intolerance found to be similar in animals and humans

People are not the only ones suffering from the symptoms and problems of food intolerance and allergies.

Research finds how omega-3 supplements dampen harmful inflammatory reactions

OMEGA-3: Omega-3 fatty acids, which we primarily get through eating fatty fish, have long been thought to be good for our health.

Study provides insight into development of red blood cells

Every cell in the body, whether skin or muscle or brain, starts out as a generic cell that acquires its unique characteristics after undergoing a process of specialization. Nowhere is this process more dramatic than it is in red blood cells.

Diet determines seizure latency: Estrogen production in the brain linked to omega-3 fatty acid intake

Scientists are increasingly appreciating estrogen's role in brain health. Now for the first time, production of estrogen in the brain has been directly linked to the presence of docosahexaenoic acid (DHA).

New synthetic antifreeze could make aeroplane wing design, organ transplants more effective

The design of aeroplane wings and storing organs for transplant could both become safer and more effective, thanks to a synthetic antifreeze which prevents the growth of ice crystals, developed by researchers at the University of Warwick.

Counteracting premature aging

Aging is the continuing process of such stress exposures, and with advancing age (normal aging), we must carry lots of senescent cells within our bodies. Senescent cells also often provide some ‘bad influences’ to surrounding healthy cells; such as chronic inflammation and tumorigenesis

Goldfish survive lack of oxygen for months by converting their carbs to alcohol

A new study has shown that goldfish and similar crucian carps can live up to five months in icy lakes with extremely low or no oxygen. Evolution of the fish has enabled them to develop a set of enzymes that can help the fish convert their carbohydrates into alcohol.

Positive effects of ‘superfoods’ on people’s health

The importance of healthy eating for our well-being is scientifically proven and having a varied diet goes without saying. Part of this are the so-called superfoods, which are exploding in popularity because of their antioxidant and anti-inflammatory properties, even if we must pay attention to sensationalist promises.

Tackling food allergies: is immunotherapy the answer?

Food allergies affect approximately 8% of school children in the United States and the United Kingdom. The highest prevalence of food allergies is in Australia affecting approximately 10% of young children. It is lower in the developing world.

Accidental discovery opens up new way to find unknown viruses

A chance discovery has opened up a new method of finding unknown viruses. In research published in the journal Virus Evolution, scientists from Oxford University's Department of Zoology have revealed that Next-Generation Sequencing and its associated online DNA databases could be used in the field of viral discovery.

Kitchen sponges - play house for millions of bacteria - fresh study reports

Scientists in Germany have looked into the minute pores of a common kitchen sponge and found dreaded bacteria that could make us very ill. This is the first comprehensive study to do so. The study was published this week in Scientific Reports. Researchers write that humans spend most of their time in built environments or BE and the microbial presence in these environments is termed BE microbiome. These microbes may have a great impact on human health and wellbeing.

Cardiovascular advantages of the Mediterranean diet linked to socioeconomic status

A study conducted by a team of researchers from the Institute for Research, Hospitalization and Health Care (I.R.C.C.S.) Neuromed, Italy, states that the risk of cardiovascular disease is reduced by the Mediterranean diet; however, the benefits are subjected to highly educated or rich people alone.
