- Potential new gene editing tools uncoveredon December 3, 2021 at 6:43 pm
Few developments have rocked the biotechnology world or generated as much buzz as the discovery of CRISPR-Cas systems, a breakthrough in gene editing recognized in 2020 with a Nobel Prize. But these systems that naturally occur in bacteria are limited because they can make only small tweaks to genes. In recent years, scientists discovered a different system in bacteria that might lead to even more powerful methods for gene editing, given its unique ability to insert genes or whole sections of DNA in a genome.
- Lightweight space robot with precise control developedon December 3, 2021 at 6:40 pm
Robots are already in space. From landers on the moon to rovers on Mars and more, robots are the perfect candidates for space exploration: they can bear extreme environments while consistently repeating the same tasks in exactly the same way without tiring. Like robots on Earth, they can accomplish both dangerous and mundane jobs, from space walks to polishing a spacecraft’s surface. With space missions increasing in number and expanding in scientific scope, requiring more equipment, there’s a need for a lightweight robotic arm that can manipulate in environments difficult for humans.

- The role of messenger RNA in DNA repairon December 3, 2021 at 4:31 pm
An organism’s genome could be compared to a complex system of instructions that allows it not only to develop, but also to carry out all the activities essential to its survival. To do this, this genome needs to be expressed correctly, i.e. these instructions need to be “read” properly, and the information it contains must not be altered or degraded over time.
- Tropical forests recover after deforestationon December 3, 2021 at 4:30 pm
Tropical forests are disappearing at an alarming rate through deforestation, but they also have the potential to regrow naturally on abandoned lands. This has been shown by an international study led by scientists from Wageningen University. How a forest recovers, depends on the amount of rainfall, the age of the forest, and the functional characteristics of the tree species.
- Astronomers discover hot, dense planet with eight-hour yearon December 3, 2021 at 3:42 pm
In a new study, published in the journal Nature, the researchers show that the planet, which is 31 light years from Earth, is one of the lightest among the nearly 5,000 exoplanets (planets outside our own solar system) that are known today, with half the mass of Earth. It has a diameter of just over 9,000 kilometers—slightly larger than Mars.
- Exoplanets in debris diskson December 3, 2021 at 3:21 pm
Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment. They are common: more than about a quarter of all main-sequence stars have debris disks and, since these disks can be hard to detect, it is likely that the fraction is even higher. Current instruments are only able to detect debris disks in systems that are at least an order of magnitude more luminous than the disk generated by the solar system’s Kuiper Belt (the region extending from the orbit of Neptune at about thirty astronomical units out to about fifty au).
- Development of a single-process platform for the manufacture of graphene quantum dotson December 3, 2021 at 3:10 pm
Graphene consists of a planar structure, with carbon atoms connected in a hexagonal shape that resembles a beehive. When graphene is reduced to several nanometers (nm) in size, it becomes a graphene quantum dot that exhibits fluorescent and semiconductor properties. Graphene quantum dots can be used in various applications as a novel material, including display screens, solar cells, secondary batteries, bioimaging, lighting, photocatalysis, and sensors. Interest in graphene quantum dots is growing, because recent research has demonstrated that controlling the proportion of heteroatoms (such as nitrogen, sulfur, and phosphorous) within the carbon structures of certain materials enhances their optical, electrical, and catalytic properties.

- CMS collaboration homes in on Higgs boson’s lifetimeon December 3, 2021 at 2:55 pm
The Higgs boson doesn’t stick around for long. Once it is created in particle collisions, the famed particle lives for a mere less than a trillionth of a billionth of a second or, more precisely, 1.6 x 10-22 seconds. According to theory, that is, for so far experiments have only been able to set bounds on the value of the particle’s lifetime or to determine this property with a large uncertainty. Until now. In a new study, the CMS collaboration reports a value for the particle’s lifetime that has a small enough uncertainty to confirm that the Higgs boson does have such a short lifetime.
- Host and resident bacteria join forces to control fungi in plant rootson December 3, 2021 at 2:45 pm
In nature, the roots of healthy plants are colonized by complex microbial communities of bacteria and filamentous eukaryotes (i.e., fungi and oomycetes, Fig. 1), the composition of which profoundly influences plant health. Maintaining a microbial equilibrium in their roots is very important for plants to remain healthy, however, the means by which this is achieved by plants is still largely unknown. Now, in a new study published in PNAS, Stéphane Hacquard and his colleagues from the Department of Plant-Microbe Interactions at the MPIPZ in Cologne, Germany, shed light on the host and microbial factors that are required to maintain a beneficial relationship between plant roots and their diverse microbial partners.
- Artificial material protects light states on smallest length scaleson December 3, 2021 at 2:45 pm
Light not only plays a key role as an information carrier for optical computer chips, particularly for the next generation of quantum computers. Its lossless guidance around sharp corners on tiny chips and the precise control of its interaction with other light are the focus of research worldwide. Scientists at Paderborn University have now demonstrated the spatial confinement of a light wave to a point smaller than the wavelength in a topological photonic crystal. These are artificial electromagnetic materials that facilitate robust manipulation of light. The state is protected by special properties and is important for quantum chips, for example. The findings have now been published in Science Advances.

- Spiders’ motion on a web studied as electrons orbiting a nucleuson December 3, 2021 at 2:21 pm
The tiny male golden orb-weaving spider faces a considerable challenge when searching for a mate. He is a fraction of the size of the massive female, but must carefully enter her web and approach her without being noticed, because the cannibalistic female will kill and eat him if he makes one wrong move on her web. Add to this gamble the competition he faces from other males also on the delicate arena of the web, and you have a complex optimization problem that even human analysts would find daunting. Yet these little spiders barely have what we would recognize as a brain. How then do they manage? This is a question that has captivated Alex Jordan and members of his lab at the Max Planck Institute of Animal Behavior for over a decade. Now, teaming up with researchers from the Weizmann Institute of Science, they are closer to an answer.
