| Turning white blood cells into medicinal microrobots with light Posted: 13 Jul 2022 08:46 AM PDT Medicinal microrobots could help physicians better treat and prevent diseases. But most of these devices are made with synthetic materials that trigger immune responses in vivo. Now, for the first time, researchers have used lasers to precisely control neutrophils -- a type of white blood cell -- as a natural, biocompatible microrobot in living fish. The 'neutrobots' performed multiple tasks, showing they could someday deliver drugs to precise locations in the body. |
| Longer lasting sodium-ion batteries on the horizon Posted: 13 Jul 2022 08:46 AM PDT A new longer-lasting sodium-ion battery design is much more durable and reliable in lab tests. After 300 charging cycles, it retained 90 percent of its charging capacity. |
| Scientists propose solution to a long-puzzling fusion problem Posted: 13 Jul 2022 08:46 AM PDT Researchers demonstrate explanation of paradox that could apply to all spherical tokamaks, cost-effective candidates to model a fusion pilot plant. |
| Researchers find the missing photonic link to enable an all-silicon quantum internet Posted: 13 Jul 2022 08:45 AM PDT Researchers have made a crucial breakthrough in the development of quantum technology. Their research describes their observations of over 150,000 silicon 'T center' photon-spin qubits, an important milestone that unlocks immediate opportunities to construct massively scalable quantum computers and the quantum internet that will connect them. |
| Efficient, stable, and eco-friendly thermoelectric material discovered Posted: 12 Jul 2022 11:14 AM PDT A thermoelectric metal oxide film with a thermoelectric figure of merit of ~0.55 at 600°C has been discovered, opening new avenues towards the widespread use of thermoelectric converters. |
| 3D printing nickel single crystals using laser additive manufacturing technology Posted: 12 Jul 2022 11:12 AM PDT Engineers have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius, flat-top laser beam (i.e., a laser beam whose intensity is uniform across a cross-section of the beam). This technique may be used to fabricate a wide variety of single-crystalline materials, including heat-resistant materials for jet engines and gas turbines. |
| A proof of odd-parity superconductivity Posted: 12 Jul 2022 11:12 AM PDT Superconductivity is a fascinating state of matter in which an electrical current can flow without any resistance. Usually, it can exist in two forms. One is destroyed easily with a magnetic field and has 'even parity', i.e. it has a point symmetric wave function with respect to an inversion point, and one which is stable in magnetic fields applied in certain directions and has 'odd parity', i.e. it has an antisymmetric wave function. |
| How do cells react to micro- and nanoplastics? Posted: 12 Jul 2022 07:27 AM PDT The smaller plastic particles are, the more easily they can be taken up by cells. In addition, the shape, surface and chemical properties play an important role in answering the question of how the particles could affect human tissue, according to new research. |
| Research team accelerates imaging techniques for capturing small molecules' structures Posted: 12 Jul 2022 07:27 AM PDT A new research effort is accelerating imaging techniques to visualize structures of small molecules clearly -- a process once thought impossible. Their discovery unleashes endless potential in improving everyday life applications -- from plastics to pharmaceuticals. |
| Researchers remeasure gravitational constant Posted: 12 Jul 2022 07:27 AM PDT Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great potential for testing one of the most fundamental laws of nature. |
| How environmentally responsible is lithium brine mining? It depends on how old the water is Posted: 12 Jul 2022 07:26 AM PDT A groundbreaking new study comprehensively accounts for the hydrological impact of lithium mining. Since lithium is the key component of the lithium-ion batteries that are crucial for the transition away from fossil fuels and towards green energy, it is critical to fully understand how to responsibly obtain the precious element. |
| Future smart homes could be powered with electronics built on stones Posted: 11 Jul 2022 10:53 AM PDT What if you could power the smart thermostats, speakers and lights in your home with a kitchen countertop? Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage with these materials, researchers have fabricated microsupercapacitors onto the surface of stone tiles. The devices are durable and easily scaled up for customizable 3D power supplies. |
| A boost in performance in fiber-integrated quantum memories Posted: 11 Jul 2022 08:18 AM PDT Researchers report the demonstration of entanglement between a fiber-integrated quantum memory and a telecommunications-wavelength photon. |
| Easy and inexpensive method for linking other molecules to DNA sequences with desired functions Posted: 11 Jul 2022 06:52 AM PDT The development of DNA-/RNA-based drugs, like COVID-19 vaccines, is exploding. Current methods are costly, but researchers are finding effective and inexpensive method for producing stable, modified DNA sequences for these modern-type drugs. |
