Excess sitting linked to coronary artery calcification, an early indicator of...
Sitting for many hours per day is associated with increased coronary artery calcification, a marker of subclinical heart disease that can increase the risk of a heart attack, according to research. Coronary artery disease is the most common type of heart disease and the leading cause of death in the...

Hot flashes at younger age may signal greater cardiovascular risk
Women who experience hot flashes earlier in life appear to have poorer endothelial function -- the earliest sign of cardiovascular disease -- than women who have hot flashes later in life or not at all, according to two new studies.

Women don't get to hospital fast enough during heart attack
Women suffering a heart attack wait much longer than men to call emergency medical services and face significantly longer delays getting to a hospital equipped to care for them, putting women at greater risk for adverse outcomes.

Elusive El Niño arrives: Forecasters predict it will stay weak, have little i...
The long-anticipated El Niño has finally arrived, according to forecasters with NOAA's Climate Prediction Center. In their updated monthly outlook released today, forecasters issued an El Niño Advisory to declare the arrival of the ocean-atmospheric phenomenon marked by warmer-than-average sea surfa...

How healthy is genetically modified soybean oil?
Soybean oil accounts for more than 90 percent of all the seed oil production in the United States. Genetically modified soybean oil, made from seeds of GM soybean plants, was recently introduced into the food supply on the premise that it is healthier than conventional soybean oil. But is that premi...

Snffing out origins of methane: instrument identifies methane's origins in m...
Methane is a potent greenhouse gas, second only to carbon dioxide in its capacity to trap heat in Earth's atmosphere for a long time. The gas can originate from lakes and swamps, natural-gas pipelines, deep-sea vents, and livestock. Understanding the sources of methane, and how the gas is formed, co...

Nutrient pollution damages streams in ways previously unknown, ecologists find
An important food resource has been disappearing from streams without anyone noticing until now. Ecologists reports that nutrient pollution causes a significant loss of forest-derived carbon from stream ecosystems, reducing the ability of streams to support aquatic life.

Mars: The planet that lost an ocean's worth of water
A primitive ocean on Mars held more water than Earth's Arctic Ocean, and covered a greater portion of the planet's surface than the Atlantic Ocean does on Earth, according to new results published today. An international team of scientists used ESO's Very Large Telescope, along with instruments at t...

Hubble sees supernova split into four images by cosmic lens
Astronomers have spotted for the first time a distant supernova split into four images. The multiple images of the exploding star are caused by the powerful gravity of a foreground elliptical galaxy embedded in a massive cluster of galaxies.

Gut microbial mix relates to stages of blood sugar control
The composition of intestinal bacteria and other micro-organisms -- called the gut microbiota -- changes over time in unhealthy ways in black men who are prediabetic, a new study finds.

Oxytocin nasal spray causes men to eat fewer calories
A synthetic nasal formulation of the hormone oxytocin reduced caloric intake in healthy men, particularly consumption of fatty foods, after a single treatment, a new study finds. The results confirm those of animal studies showing oxytocin reduces food intake.

Male partner's healthier lifestyle may help infertile obese female conceive
Male partners of infertile obese females may increase the odds of conceiving a child by improving their own weight and dietary habits, preliminary results from a pilot study suggest.

Abnormal brain rhythms tied to problems with thinking in schizophrenia
By studying specially bred mice with specific developmental and cognitive traits resembling those seen in schizophrenia, researchers have provided new evidence that abnormal rhythmic activity in particular brain cells contributes to problems with learning, attention, and decision-making in individua...

Drug to control appetite could also fight anxiety
Did you know that our body produces its own marijuana-like compound to protect us against anxiety? A study reveals a new biological pathway that regulates this system and suggests that a drug currently in clinical trials to treat obesity might also provide an attractive way to combat anxiety disorde...

In vivo CRISPR-Cas9 screen sheds light on cancer metastasis, tumor evolution
For the first time, CRISPR-Cas9 gene-editing technology has been employed in a whole organism model to systematically target every gene in the genome. A team of scientists has pioneered the use of this technology to 'knock out,' or turn off, all genes across the genome systematically in an animal mo...

From chick to bedside: Removing the Wnt barrier
Kick starting a process that might repair the damage done in cerebral palsy and multiple sclerosis could begin with disabling a driver that helps block regeneration, say researchers.

Twin copies of gene pair up in embryonic stem cells at critical moment in dif...
The two alleles of Oct4, a gene important in embryonic stem cells, don't remain separate in the nucleus of stem cells but rather pair up, at the developmental point at which stem cells begin their maturation into specific cell types, scientists have discovered.

Phthalates potentially alter levels of a pregnancy hormone that influences se...
Exposure to hormone-altering chemicals called phthalates -- which are found in many plastics, foods and personal care products -- early in pregnancy is associated with a disruption in an essential pregnancy hormone and adversely affects the masculinization of male genitals in the baby, according to ...

Nine steps to survive 'most explosive era of infrastructure expansion in huma...
A team of scientists call attention to nine issues that must be considered if there is to be any hope of limiting the environmental impacts of the ongoing expansion of new roads, road improvements, energy projects, and more now underway or 'coming soon' in countries all around the world.

Mutation in APC2 gene causes Sotos features
Sotos syndrome is a congenital syndrome that is characterized by varying degrees of mental retardation and a large head circumference etc. It is known that 90 percent of Sotos syndrome patients have mutations in the NSD1 gene. This time, an international research group has revealed that mutation in ...
