Scientists successfully extract insect DNA from amber – from 2014

Scientists have successfully extracted DNA from insects trapped in amber. But before you start dreaming of a certain park, there’s one huge caveat to mention – any creatures you might revive from this would hail from the not-so-distant past of about 20… Continue reading Scientists successfully extract insect DNA from amber – from 2014

Colloidal diamonds self-assembled in breakthrough for photonics

Engineers have developed a simple way to make colloidal diamonds that self-assemble. These structures have traditionally been tricky to manufacture in bulk, but with this new method they could be used to help make better photonic devices.Continue Readi… Continue reading Colloidal diamonds self-assembled in breakthrough for photonics

DNA study rediscovers frog species lost to science for 50 years

It can be hard to determine if an animal is extinct or just really good at hiding, especially for already-elusive creatures like frogs. But now, researchers have demonstrated a new way to track lost species by searching for their loose DNA in the envir… Continue reading DNA study rediscovers frog species lost to science for 50 years

Portable test kit quickly detects coral-eating starfish on reefs

As if they don’t already face enough challenges from bleaching, many of the world’s coral reefs are currently being eaten by the crown-of-thorns starfish. A simple new portable test kit, however, could detect their presence sooner than ever before.Cont… Continue reading Portable test kit quickly detects coral-eating starfish on reefs

Childhood trauma found to accelerate biological signs of aging

A compelling new meta-analysis from a trio of accomplished psychologists suggests violent or traumatic experiences in childhood can accelerate biological signs of aging. Early puberty, rapid cellular aging, and structural brain changes could all be lin… Continue reading Childhood trauma found to accelerate biological signs of aging

Ancient cave “hotel” places humans in the Americas 30,000 years ago

It’s generally believed that the Clovis people were the first humans to inhabit the Americas, as long as 15,000 years ago. But now archaeologists have found evidence in a cave in Mexico that suggests humans visited as early as 30,000 years ago – althou… Continue reading Ancient cave “hotel” places humans in the Americas 30,000 years ago

Cancer blood test catches disease 4 years before conventional methods

A new cancer-detecting blood test has been found to catch five common types of cancer up to four years before any other conventional diagnostic tool. Further verification is needed before the test is clinically available but the researchers suggest thi… Continue reading Cancer blood test catches disease 4 years before conventional methods

Human X chromosome completely sequenced for the first time

As close as we’ve gotten to sequencing the entire human genome, there are still a few gaps. But now geneticists have plugged a major one in a landmark new study, by sequencing the entire human X chromosome from end to end, covering more than three mill… Continue reading Human X chromosome completely sequenced for the first time

DNA suggests Polynesian and Native American contact pre-European arrival

An archaeological conundrum may have been solved by DNA analyses carried out by a team of Stanford Medicine scientists led by Alexander Ioannidis that indicates Native Americans and Polynesians came into contact centuries before the arrival of the firs… Continue reading DNA suggests Polynesian and Native American contact pre-European arrival
