Science authors David Quammen and Carl Zimmer both have recent books showing that DNA is not only passed down from our ancestors but can also come from viruses, siblings, and even our children.
Geneticist David Reich discusses DNA findings that show how migration shaped Europe and southern Asia, and that “No population is, or ever could be, pure.”
Harvard researchers are using a chemical process known as triplet fusion upconversion to transform near-infrared photons into high-energy photons. The high-energy photons could be used in a huge range of applications, including a new type of precisely targeted chemotherapy, in which low-energy infrared lasers that penetrate deep into the body could be used to transform innocuous compounds into cancer-fighting drugs.
A new Harvard study suggests that although the congenitally blind experience abstract visual phenomena such as rainbows and color differently, they still share with the sighted a common understanding of them.
A new study shows that African grey parrots can perform some cognitive tasks at levels beyond those of 5-year-old humans. The results not only suggest that humans aren’t the only species capable of making complex inferences, but also point to flaws in a widely used test of animal intelligence.
Researchers have created the first cellular atlas of the primate retina and discovered that, while the fovea and peripheral retina share most of the same cell types, the cells are in different proportions, and show different gene expression patterns.
Despite often being portrayed as living fossils that have remained virtually unchanged for millions of years, a new Harvard study shows crocodiles have repeatedly altered their developmental patterns, leading to much of the diversity found in modern, living crocodiles.
In a first-of-its-kind study, findings suggest that continued ocean warming and acidification could impact everything from how fish move to how they eat.
A new study, which used everything from tide gauges to GPS data to paint the most accurate picture ever of sea-level rise along the East Coast of the U.S., is suggesting that in addition to rising seas, communities along the coast may also have to contend with the land sinking.
In an effort to understand how colibactin, a compound produced by certain strains of E. coli, may be connected to the development of colorectal cancer, Harvard researchers are exploring how the compound damages DNA to produce DNA adducts.
Hal Harvey, the CEO of Energy Innovation, a San Francisco–based energy and environmental policy firm, encouraged an audience at Harvard to get involved in about innovative ways to address climate change.
Now research suggests that a nerve cells’ axons may be making decisions on their own, challenging the dogma that the nucleus and cell body are the control centers of the neuron.
Researchers investigate how centimeter-sized termites, without architects, engineers or foremen, can build complex, long-standing, meter-sized structures all over the world.
A study in which mice were released into outdoor enclosures to track how light- and dark-colored specimens survived confirms that mice survive better in similarly colored habitats, providing insights into evolution.
To understand the strain that space flight places on the body, NASA-affiliated researcher Brinda Rana has been examining the molecular changes in the twin astronauts Scott and Mark Kelly for five years.
For her research into the reproducibility crisis, Radcliffe fellow Nicole C. Nelson is conducting oral histories with scientists and assembling a database of academic and news articles.
A recent study shows that a gene that produces surfactant protein c — a key protein for lung function — is expressed in the skin and mouths of lungless salamanders, suggesting it also plays an important role for cutaneous respiration.
Steps to limit climate change require not only scientific advances but social and policy changes that spread the benefits of alternative energy sources, professor Daniel M. Kammen said in Radcliffe lecture.
Computer science students examine issues such as privacy, censorship, and fake news in courses co-designed by philosophy professors as Harvard works to embed ethics in the curriculum, creating a national model.
CT scans reveal evidence of atherosclerosis in 16th-century mummies from Greenland. The mummies were of particular interest due to their diet, which relied on fish — commonly touted as a heart-healthy diet.
Combining two recently developed technologies — expansion microscopy and lattice light-sheet microscopy — researchers have developed a method that yields high-resolution visualizations of large volumes of brain tissue, at speeds roughly 1,000 times faster than other methods.
Researchers have created a micro-robot whose electroadhesive foot pads allow it to climb on vertical and upside-down conductive surfaces, such as the inside walls of a jet engine. Groups of micro-robots could one day be used to inspect complicated machinery and detect safety issues sooner, while reducing maintenance costs.
Getting the perfect-size artificial heart valve without ever actually looking at the patient’s heart was a challenge … until now. Researchers at the Wyss at Harvard University have created a 3-D printing workflow that allows cardiologists to evaluate how different valve sizes will interact with each patient’s unique anatomy
