Females less likely to heal from ACL injuries than males

A study using an animal model is the first to examine tissue healing following chronic overuse injuries of the anterior cruciate ligament. Females also are less able to heal from these microtraumas than males.

Honey bees may inherit altruistic behavior from their mothers

True altruism is rare behavior in animals, but a new study by Penn State researchers has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent they inherit it from.

Climate-driven extreme heat may make parts of Earth too hot for humans

If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves.

Podcast explores impacts of inter-species microbial interactions

Over the past two decades, scientists have discovered that all multicellular life forms on Earth, including human beings, play host to a multitude of microorganisms.

Novel hydrogel finds new aptamers, or ‘chemical antibodies,’ in days

One double-helix strand of DNA could extend six feet, but it is so tightly coiled that it packs an entire sequence of nucleotides into the tiny nucleus of a cell. If that same DNA was instead split into two strands and divided into many, many short pieces, it would become trillions of uniquely folded 3D molecular structures, capable of bonding to and possibly manipulating specifically shaped molecules — if they’re the perfect fit.
