Humans
We summarize the week's scientific breakthroughs every Thursday.
- Psychology
Saying ‘I’ and ‘me’ all the time doesn’t make you a narcissist
People who utter lots of first-person singular pronouns such as "I" and "me" score no higher on narcissism questionnaires than peers who engage in little "I"-talk.
- Genetics
Contagious cancer found in clams
A soft-shell clam disease is just the third example of a contagious cancer.
- Genetics
Mummies tell tuberculosis tales from the crypt
Hungarian mummies contracted multiple strains of tuberculosis at the same time, researchers find.
- Anthropology
Beads suggest culture blocked farming in Northern Europe
Baltic hunter-gatherers blocked farming’s spread from south.
- Humans
Natural selection may be growing taller Dutch people
Over the past 200 years, natural selection may have driven the evolution of taller Dutch people, researchers posit.
- Health & Medicine
Mutation regions mapped on genes that cause breast and ovarian cancer
An analysis of mutated BRCA genes could someday be used for personalized medicine in the fight against breast and ovarian cancer.
- Neuroscience
Brains may be wired to count calories, make healthy choices
Fruit flies appear to make memories of the calories in the food they eat, an observation that may have implications for weight control in humans.
- Health & Medicine
Pink blobs of hope in cancer-targeting quest
Cancer drugs coated with plastic can reach a mouse’s lungs for targeted delivery, but steering the capsules to the right spots can be a challenge.
- Anthropology
Ancient Homo fossils found in Kenya
Finds from three individuals add to skeletal diversity of early members of human genus.
- Health & Medicine
Early birth control study probed effectiveness of pill
A 1960s study probed birth control pills’ effectiveness for women. Researchers are still trying to make a pill for men.
- Anthropology
Footprints offer clues about daily hominid life
Early male members of the human genus spent a lot of time together by the water, as their footprints attest.
- Health & Medicine
A more accurate prenatal test to predict Down syndrome
A test to detect genetic problems such as Down syndrome examines a baby’s DNA in the mother’s blood and may limit the need for more invasive screening.
