Researchers studied double-strand breaks with complex damage and found that enzyme tools to resect the breaks are highly specific to the type of break to be repaired.

New research suggests that people's ideal partner preferences do not reflect any unique personal insight.
Scientists have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously.
A research team recently demonstrated active manipulation of chromatic dispersion, achieving achromatic focusing within a designated broadband.
Researchers have created a new liquid battery with components that can remain molten at room temperature. Other liquid batteries must be kept at 240 degrees Celsius for their components to stay molten.
There's a fairly large flaw in the way that programmers are currently addressing ethical concerns related to artificial intelligence and autonomous vehicles (AVs). Namely, existing approaches don't account for the fact that people might try to use AVs to do something bad.
Researchers have taken a major step toward a theoretical first-principles description of neutrinoless double-beta decay. Observing this yet-unconfirmed rare nuclear process would have important implications for particle physics and cosmology. Theoretical simulations are essential to planning and evaluating proposed experiments.
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this ''dead water'' being understood. A team has explained this phenomenon for the first time.
Dinosaurs and pterosaurs may be known for their remarkable size, but a newly described species that lived around 237 million years ago suggests that they originated from extremely small ancestors. The fossil reptile, named Kongonaphon kely, or 'tiny bug slayer,' would have stood just 10 centimeters tall. The study may help explain the origins of flight in pterosaurs, the presence of 'fuzz' on both...
A new study provides first direct evidence for Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to...
Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.
In a study of New York state apple orchards, plant pathologists have identified a new fungal pathogen that causes bitter rot disease in apples.
Motherhood takes over the brain's decision-making regions to prioritize caring for offspring, according to new research.
Archaeologists have combined the latest scientific methods to offer new insights into life during the Norman Conquest of England. Until now, the story of the Conquest has primarily been told from evidence of the elite classes of the time. But little has been known about how it affected everyday people's lives.
Researchers have developed a new silicon chip with major applications in lidar systems for self-driving cars and smart phones.
Layered van der Waals materials are of high interest for electronic and photonic applications, according to researchers who provide new insights into the interactions of layered materials with laser and electron beams.
Tiny eye movements can be used as an index of humans' ability to anticipate relevant information in the environment independent of the information's sensory modality.
Researchers have discovered a new class of pipeline drugs to relieve pain and reduce fever without the danger of addiction or damage to the liver or kidneys.
Frailty and immune decline are two main features of old age. Researchers now demonstrate in an animal model that these two age-related impairments can be halted and even partially reversed using a novel cell-based therapeutic approach.
In an effort to improve large touchscreens, LED light panels and window-mounted infrared solar cells, researchers have made plastic conductive while also making it more transparent.
A new analysis of white dwarf stars supports their role as a key source of carbon in galaxies. Every carbon atom in the universe was created by stars, but astrophysicists still debate which types of stars are the primary source of the carbon in our galaxy. Some studies favor low-mass stars that blew off their envelopes in stellar winds and became white dwarfs, while others favor massive stars that...
Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles. It is continuously generated by the motion of liquid iron in Earth's outer core, a phenomenon called the geodynamo. Despite its fundamental importance, many questions remain unanswered about the geodynamo's origin. New work examines how the presence of lighter elements in the...
The active agents of many drugs are natural products, so called because often only microorganisms are able to produce the complex structures. Similar to the production line in a factory, large enzyme complexes put these active agent molecules together. Biologists have now succeeded in investigating the basic mechanisms of one of these molecular factories.
The brain has a high energy demand and reacts very sensitively to oxygen deficiency. Neurobiologists have now succeeded for the first time in directly correlating oxygen consumption with the activity of certain nerve cells.
Liquid droplets formed from DNA display a peculiar response to enzymes. An international collaboration has now been able to explain the mechanisms behind bubble formation.
