We summarize the week's scientific breakthroughs every Thursday.
- Genetics
Horses may have been domesticated twice. Only one attempt stuck
Genetic evidence suggests that the ancestors of domestic horses were bred for mobility about 4,200 years ago.
- Science & Society
Scientists are fixing flawed forensics that can lead to wrongful convictions
People have been wrongly jailed for forensic failures. Scientists are working to improve police lineups, fingerprinting and even DNA analysis.
- Health & Medicine
Bird flu can infect cats. What does that mean for their people?
Pet owners can take precautions to avoid H5N1, such as keeping cats indoors and making sure they don’t eat raw meat or milk.
- Health & Medicine
Privacy remains an issue with several women’s health apps
Inconsistent privacy policies and dodgy data collection in popular fertility and pregnancy tracking apps put women’s health information at risk.
- Health & Medicine
Malnutrition’s effects on the body don’t end when food arrives
Children may struggle with inflammation, a weakened immune system and gut problems. New treatments may repair some damage.
- Neuroscience
Biological puzzles abound in an up-close look at a human brain
Mirror-image nerve cells, tight bonds between neuron pairs and surprising axon swirls abound in a bit of gray matter smaller than a grain of rice.
- Health & Medicine
Young people’s use of diabetes and weight loss drugs is up 600 percent
Young people’s use of diabetes and weight loss drugs like Ozempic and Wegovy is surging, especially among females ages 18 to 25.
- Neuroscience
Two distinct neural pathways may make opioids like fentanyl so addictive
A study in mice looked at how feelings of reward and withdrawal that opioids trigger play out in two separate circuits in the brain.
- Health & Medicine
Human body lice could harbor the plague and spread it through biting
Rats and fleas previously got all the blame, but humans’ own parasites could be involved.
- Archaeology
One of the world’s earliest farming villages housed surprisingly few people
Hundreds, not thousands, occupied the Turkish site of Çatalhöyük nearly 9,000 years ago, undermining arguments for a Neolithic social revolution.
- Health & Medicine
Burning the stomach lining reduces the ‘hunger hormone’ and cuts weight
An experimental weight loss procedure blasts the stomach lining with heat to curb hunger and cut pounds.
- Health & Medicine
Genetic analyses of the bird flu virus unveil its evolution and potential
The H5N1 outbreak in cattle is giving flashbacks to the COVID pandemic. But this time is different.
