In April 2020, a bull calf named Cosmo was born to a team of scientists. This probably wouldn’t normally be news except that this particular bouncing baby boy had his genome edited as an embryo, to make him more likely to produce male offspring.

A new method for determining the sex of human remains based on proteins extracted from tooth enamel has proven more reliable than those based on DNA or bone anatomy.

A study from scientists at the University of California, Davis, has found unpasteurized milk, commonly known as raw milk, holds large volumes of antimicrobial-resistant genes which can swiftly spawn dangerous bacteria when left at room temperature.

Many readers are likely already familiar with the oximeters that measure blood oxygen levels via the patient's finger. Well, scientists have now developed a device that works on the same principle, but it can be non-invasively used on unborn fetuses.

Presently, in order to check the level of opioid drugs in a person's bloodstream, a blood sample must be taken. Things may soon be getting much less invasive, however, as scientists have now developed a breath test that does the job.

ScienceArchaeologists have found ancient tools at a dig site in Mongolia, indicating that humans were on the scene about 45,000 years ago, which is much earlier than current evidence suggests. There’s also a chance that the site is one spot where our ancestors mingled with the mysterious Denisovans.

Our bodies aren't great at regeneration. Other creatures have mastered this skill though, and now scientists at the University of California Davis (UC Davis) and Harvard have sequenced the RNA transcripts for the immortal hydra and figured out how it manages to do just that.

While exploring the “dark heart” of the human genome, geneticists have now found some of the most ancient pieces of DNA, inherited from Neanderthals and an as-yet-unknown human relative, which may be affecting our sense of smell to this day.

A recent study indicated that fewer horseflies land on mannequins with stripes painted onto them. The research was inspired by observations that zebras also tend not to be bothered much by flies. A separate study now offers an explanation as to why that's the case.

Even if you love olives out of the jar, chances are you wouldn't like them straight off the tree. When freshly-picked, they contain bitter-tasting chemical compounds that have to be removed via an environmentally-iffy process. According to a new study, however, there could be a greener alternative.

Although the platypus may seem like a real oddball of an animal, it turns out that a prehistoric reptile had some of the same key features. Like the platypus (which is a mammal, albeit one that lays eggs), Eretmorhipis carrolldongi had small eyes, four flippers, and a flexible duck-like bill.

ScienceWhile it's kind of people to set up hummingbird feeders in their back yards, some scientists are wondering if the practise may be causing more harm than good. In an effort to better understand the issue, researchers equipped a group of the birds with tags that were read by devices at feeders.
