We summarize the week's scientific breakthroughs every Thursday.
- Animals
Chimps raised among humans may have problems as adults
Chimpanzees taken away from their mothers and raised to be pets or entertainers have problems relating to other chimps later in life.
- Neuroscience
Dyslexic brain may solve some math problems in a roundabout way
Children with dyslexia rely heavily on right brain to do addition problems.
- Ecosystems
‘Where Do Camels Belong?’ explores invasive species
Ecologist Ken Thompson takes a closer look at the impacts (or lack thereof) of invasive species.
- Life
Thoughtful approach to antibiotic resistance
Changing how people think about antibiotics is already showing promise in reducing antibiotic use and costs. It’s doubtful, however, that any single strategy will be enough.
- Paleontology
3-D scans reveal secrets of extinct creatures
Paleontologists can dig into fossils without destroying them and see what’s inside using 3-D scanning. What they’re learning helps bring the past to life.
- Plants
Borrowed genes raise hopes for fixing “slow and confused” plant enzyme
Inserting some bacterial Rubisco chemistry into a plant might one day boost photosynthesis and help raise crop yields.
- Health & Medicine
Doctors enlisted to turn the tide on antibiotic resistance
Antibiotic stewardship requires education, diligence, and changes in prescribing. At some hospitals, it’s beginning to halt a dangerous trend.
- Life
Molecule boosts numbers of stem cells in umbilical cord blood
A new molecule multiplies stem cells in umbilical cord blood. More blood-making stem cells could mean more effective transplants for people with blood cancers.
- Genetics
Genetic data rewrite the prehistory of Europe
The genomes of nine ancient and 2,345 living humans have changed the story of modern Europeans' origins.
- Math
Sharks’ hunting paths may not be driven by math
Penguins, tuna, sharks and other marine hunters have been shown to use math to find food. But simulations suggest the behavior is a result of rough water, not complex calculation.
- Life
Artificial sweeteners may tip scales toward metabolic problems
The artificial sweetener saccharin meddles with the gut’s microbial community, setting in motion metabolic changes associated with obesity and diabetes.
- Anthropology
Strategy, not habitat loss, leads chimps to kill rivals
Human impacts on chimpanzees have not increased their violence.
