Egg-free surrogate chickens can save rare poultry breeds

Egg-free surrogate chickens can save rare poultry breeds

Washington D.C. [USA], Feb. 18 : To boost breeding of endangered poultry breeds, Briton researchers have come up with gene-editing techniques for the rare breeds to use them as surrogates that cannot produce their own chicks.

The advance -- using gene-editing techniques -- could help to boost breeding of endangered birds, as well as improving production of commercial hens, researchers say.

The appeared in the journal Development.

Researchers explained that donor primordial germ cells from other breeds could be implanted into the gene-edited chickens as they are developing inside an egg. The surrogate hens would then grow up to produce eggs containing all of the genetic information from the donor breeds.

Include green leafy vegetables, nuts in your daughter's diet to boost her grades

Include green leafy vegetables, nuts in your daughter's diet to boost her grades

Washington D. C. [USA], Jan. 26 : Dear parents, boost your daughter's iron intake with green leafy vegetables, nuts, beans and pulses as a new study reveals that physically fit female students with normal iron levels may perform better academically.

Researchers from the University of Nebraska-Lincoln and Pennsylvania State University have found that a student's fitness level and iron status could be the difference between making an A or a B.

The findings, published in the journal of Nutrition, suggest that the difference in grade point average was as much as 0.34 -- enough to drop or increase a letter grade.

Scientists discover 'BioClay' for pest-free crops

Scientists discover 'BioClay' for pest-free crops

Washington D.C. [USA], Jan. 11 : Scientists, including an Indian-origin researcher, have found a nano-sized degradable clay, an alternative to chemicals and pesticides, that protects plants from specific disease-causing pathogens.

Researcher Neena Mitter from University of Queensland in Australia said BioClay - an environmentally sustainable alternative to chemicals and pesticides - could be a game-changer for crop protection.

The study was recently published in Nature Plants.

"In agriculture, the need for new control agents grows each year, driven by demand for greater production, the effects of climate change, community and regulatory demands and toxicity and pesticide resistance," she said.

Don't prove how macho you are at risk of overeating

Don't prove how macho you are at risk of overeating

Washington D.C. [USA], Dec. 6 : Does food at social gatherings tempt you? A team of researchers has found that men in particular demonstrate their virility and strength on parties or at holiday meals at risk of overeating.

The study has been published in the journal Frontiers in Nutrition.

"Even if men aren't thinking about it, eating more than a friend tends to be understood as a demonstration of virility and strength," said co-author of the study Kevin Kniffin from Cornell Food and Brand Lab.

The researchers recruited college going students of similar weight to participate in either a competitive chicken wing eating challenge with cheering spectators or a competitive chicken wing eating challenge with no spectators.

Attention men! Frequent exercise can improve sperm quality

Attention men! Frequent exercise can improve sperm quality

Washington D.C. [USA], Dec. 6 : Moderate Intensity Continuous Training (MICT) for three and five times a week is linked to improved sperm count and other measures of sperm quality in just a six months, reveals a study.

The study was published in the journal Reproduction.

Researchers from Urmia University in Iran found that men exercising moderately and continuously improved their sperm quality more than those following popular intensive exercise programs like High intensity interval training (HIIT).

The current advice for men, who are seeking to improve their chances of conceiving include combining healthy eating with regular exercise while giving up smoking and reducing the intake of alcohol.

Scientists find shape matters when light meets atom

Scientists find shape matters when light meets atom

Washington D. C [US], Dec. 4 : In a recent study published in the Natures Communications journal, researchers have shown that a photon's shape also affects how it is absorbed by a single atom.

Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what you're looking at.

Some photons reflect off, reaching your eyes, others get absorbed. The main decider of which happens is the photon's energy - its colour.

But look closely at the moment that light meets matter, and there's more to be discovered. We don't often think of photons as being spread out in time and space and thus having a shape, but the ones in this experiment were some four meters long.

Researchers develop radiation free technique to image brain molecules

WashingtonD.C [US], Dec. 3 : In a path breaking discovery, scientists from Massachusetts Institute of Technology have developed a new probe that allows them to image brain molecules without using any chemical or radioactive labels.

Currently, the gold standard approach to imaging molecules in the brain is to tag them with radioactive probes.

However, these probes offer low resolution and they can't easily be used to watch dynamic events, said researcher Alan Jasanoff.

Research sets new target for brain cancer therapy

Research sets new target for brain cancer therapy

Washington D.C [US], Dec. 3 : A recent study suggests that two recently discovered genetic differences between brain cancer cells and normal tissue cells could offer clues to tumor behavior and potential new targets for therapy.

Published in Acta Neuropathologica, the study identified alterations in a protein known as ATRX in human brain tumors that arise as part of a genetically inherited condition known as neurofibromatosis type 1 (NF1).

The disorder, marked initially by benign tumors on nerves, often leads to brain cancer, and although most NF1-related malignancies are nonaggressive, a fraction are "high-grade" and difficult to treat, experts say.

Cataract ups risk of depression in older adults

Cataract ups risk of depression in older adults

Washington D.C. [USA], Dec. 3 : Older adults, especially women, with cataract are more likely to have symptoms of depression, says a new study.

The study was published in the Optometry and Vision Science journal.

According to researchers from Soochow University in China, the link between cataract and depression is independent of other factors and appears strongest among older adults with lower education.

"Our study sheds further light on the complex relationship between aging, vision loss, cataract and depression and suggests that there may be a role for cataract surgery in improving mental health in the elderly," the researchers wrote.

Is saturated fat good for health?

Is saturated fat good for health?

Washington D.C [US], Dec. 3 : A recent diet intervention study (FATFUNC) raises questions regarding the validity of a diet hypothesis that has dominated for more than half a century: that dietary fat and particularly saturated fat is unhealthy for most people.

The study, published in The American Journal of Clinical Nutrition, found strikingly similar health effects of diets based on either lowly processed carbohydrates or fats.

In the randomized controlled trial, 38 men with abdominal obesity followed a dietary pattern high in either carbohydrates or fat, of which about half was saturated.

Fat mass in the abdominal region, liver and heart was measured with accurate analyses, along with a number of key risk factors for cardiovascular disease.

Scientists develop new device to detect complicated prostate cancer

Scientists develop new device to detect complicated prostate cancer

Washington D.C [US], Dec. 3 : A recent research demonstrates that a novel imaging agent can quickly and accurately detect metastasis of prostate cancer, even in areas where detection has previously been difficult.

Published in the Journal of Nuclear Medicine, the Phase 1 dose-escalation study of Zr-89-desferrioxamine-IAB2M (Zr-89-Df-IAB2M), an anti-PSMA (prostate-specific membrane antigen) minibody, in patients with metastatic prostate cancer shows its effectiveness in targeting both bone and soft tissue lesions.

"This agent is imaged faster than other PSMA-targeting imaging antibodies due to its small size and has been shown to be safe for patients," explained lead researcher Neeta Pandit-Taskar.

Hearing loss caused by chemotherapy can now be prevented

Washington D.C. [USA], Dec. 3 : In first of its kind study, researchers have developed a new treatment that can prevent chemotherapy-induced hearing loss to about half in kids and adolescents with cancer.

The results of the study have been published in Lancet Oncology.

The study found that the greatest benefit was seen in children younger than 5 years of age, who are most susceptible to, and also most affected by, cisplatin-induced hearing loss.

Investigators from Children's Hospital Los Angeles and 37 other Children's Oncology Group hospitals in the U.S. and Canada have determined that sodium thiosulfate prevents cisplatin-induced hearing loss in children and adolescents with cancer.

Research highlights association between psychological well-being and physical activity in older adults

Research highlights association between psychological well-being and physical

WashingtonD.C [US], Dec. 3 : A recent research published in the Annals of Behavioral Medicine, showed associations between psychological well-being and physical activity in adults aged 50 and older.

"Researchers have long studied how physical activity can lead to improved mood and feelings of well-being," said Julia Boehm.

Adding, "however, less well understood is whether being happy and optimistic might actually encourage a person to be physically active."

Physical activity is a key health behavior linked to better physical and mental functioning, as well as reduced risk of the leading causes of death including cancer and heart disease.

Further, psychological well-being is associated with reduced risk of cardiovascular disease, cognitive decline, and mortality.

Restaurants often skip explaining risks of undercooked meat to customers

Washington D.C [US], Dec. 2 : A recent study conducted at the North Carolina State University found that restaurants don't perform an effective job of communicating with customers when it comes to addressing risks associated with eating undercooked meat - specifically hamburgers.

Published in the Journal of Food Protection, the study also found that inaccurate information provided by servers often contradicts science-based information customers need to make informed food safety decisions.

All 50 states in the U.S. have adopted some version of the Food & Drug Administration's Model Food Code, which requires restaurants to tell customers about risks associated with undercooked meat and poultry products.
