We summarize the week's scientific breakthroughs every Thursday.
- Archaeology
An AI found a hidden Nazca Line in Peru showing a humanoid figure
An artificial intelligence program designed to go through massive datasets for hints of ancient geoglyphs called Nazca Lines has discovered a new one.
- Tech
A tiny switch could redirect light between computer chips in mere nanoseconds
Microscopic switches that ferry information using light, not electric current, could help create better, faster electronics.
- Artificial Intelligence
A will to survive might take AI to the next level
Neuroscientists argue that the biological principle of homeostasis will lead to improved, “feeling” robots.
- Physics
Trapping atoms in a laser beam offers a new way to measure gravity
A new type of experiment to measure the strength of Earth’s gravity uses atoms suspended in light rather than free-falling atoms.
- Tech
The first artificial material that follows sunlight may upgrade solar panels
Rows of tiny stemlike rods called SunBOTs orient themselves toward light, optimizing the solar energy that they can harvest.
- Tech
Here’s what it will take to adapt the power grid to higher wildfire risks
Better sensing tech on power lines and reliance on more local power sources could help avoid vast power outages like those in California in October.
- Science & Society
Bias in a common health care algorithm disproportionately hurts black patients
A machine-learning program that uses past medical costs to identify patients for extra care favors white patients over black patients, a study finds.
- Quantum Physics
Google officially lays claim to quantum supremacy
The quantum computer Sycamore reportedly performed a calculation that even the most powerful supercomputers available can’t reproduce.
- Science & Society
This year’s SN 10 enjoy the journey, not just the discovery
Meet 10 young researchers who combine persistence and passion to make headway on science’s big questions.
- Neuroscience
Maryam Shanechi designs machines to read minds
Maryam Shanechi creates computer programs that link brain and machine to one day help patients with paralysis or psychiatric disorders.
- Genetics
Stanley Qi gives CRISPR a makeover to redefine genetic engineering
By adapting CRISPR/Cas9, Stanley Qi has given genetic engineers a plethora of new tools.
