Anti-HIV medicines can cause damage to fetal hearts, research shows

New research raises concern about potential long-term harmful impact of ‘antiretroviral therapy’ on in-utero infants whose mothers are HIV-positive, but who are not infected with HIV themselves. The study shows that while the HIV medications have been successful in helping to prevent the transmission of the virus from mother to infant, they are associated with persistently impaired development of heart muscle and reduced heart performance in non-HIV-infected children whose mothers received the medicines years earlier. —> Read More Here

Self-regulation intervention boosts school readiness of at-risk children, study shows

An intervention that uses music and games to help preschoolers learn self-regulation skills is helping prepare at-risk children for kindergarten, a new study shows. Self-regulation skills — the skills that help children pay attention, follow directions, stay on task and persist through difficulty — are critical to a child’s success in kindergarten and beyond, said a co-author of the new study. —> Read More Here

New terahertz device could strengthen security

We are all familiar with the security hassles that accompany air travel. Now a new type of security detection that uses terahertz radiation is looking to prove its promise. Researchers have developed a room temperature, compact, tunable terahertz source that could lead to advances in homeland security and space exploration. Able to detect explosives, chemical agents and dangerous biological substances from safe distances, devices using terahertz waves could make public spaces more secure than ever. —> Read More Here

Rejecting unsuitable suitors is easier said than done

Rejecting unsuitable romantic partners is easy in hypothetical situations, but not so when considering a face-to-face proposition, a new study shows. “When actually faced with a potential date, we don’t like to reject a person and make them feel bad, which is not necessarily something that people anticipate when they imagine making these choices,” says the study’s lead researcher. —> Read More Here

How the hummingbird achieves its aerobatic feats

Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds. Now, the most detailed, three-dimensional aerodynamic simulation of hummingbird flight conducted to date has definitively demonstrated that the hummingbird achieves its nimble aerobatic abilities through a unique set of aerodynamic forces that are more closely aligned to those found in flying insects than to other birds. —> Read More Here

These Adorable Beagles Got A Second Chance, But Their Story Is Part Of A Much Bigger Problem

chicago 4

Few things prompt you to grab a hankie quite like seeing adorable animals taste freedom for the first time.

On Wednesday, a CBS affiliate in Chicago shared the story of four beagles getting a new lease on life after being released from unnamed research labs into the care of the Beagle Freedom Project, an animal advocacy group.

The four beagles — Casper, Jack, Bandit and Sparky — were freed in April and were fostered and ultimately adopted by families in the Chicago area. And while Shannon Keith, president and founder of the Beagle Freedom Project, said the animals are happily adjusting to their new homes, the conditions they left behind are still a reality for thousands of animals that have yet to be released.

Beagle Freedom Project workers hold the “Chicago Four” released earlier this year.

“Animal testing is still as big as it ever was,” Keith told The Huffington Post. “There are hundreds of thousands of animals in the U.S. being tested. Every animal you can think of is being used — rats to rabbits, to dogs and cats, horses, goats, pigs.”

Beagles are the most common dog breed used for animal testing because they’re “docile, friendly and —> Read More Here
