Fruit flies use corrective movements to maintain stability after injury
- ScienceDaily
- 22/11/18 20:41
Fruit flies can quickly compensate for catastrophic wing injuries, researchers found, maintaining the same stability after losing up to 40% of a wing. This finding could inform the design of versatile robots, which face the similar challenge of having to quickly adapt to mishaps in the field.
How '2D' materials expand
- ScienceDaily
- 22/11/18 20:41
Researchers developed a technique to effectively measure the thermal expansion coefficient of two-dimensional materials. With this information, engineers could more effectively and efficiently use these atomically-thin materials to develop next-generation electronic devices that can perform better and run faster than those built with conventional materials.
Asphaltene changed into graphene for composites
- ScienceDaily
- 22/11/18 20:40
The flash Joule heating process turns asphaltenes, a byproduct of crude oil production, into graphene for use in composite materials.
Can pharmacotherapies prevent alcohol use disorder in people with PTSD?
- ScienceDaily
- 22/11/18 20:40
A research team showed how drugs can reduce alcohol preference in animal models of post-traumatic stress disorder.
'Butterfly bot' is fastest swimming soft robot yet
- ScienceDaily
- 22/11/18 20:31
Inspired by the biomechanics of the manta ray, researchers have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots. The robots are called 'butterfly bots,' because their swimming motion resembles the way a person's arms move when they are swimming the butterfly stroke.
Dietary change starves cancer cells, overcoming treatment resistance
- ScienceDaily
- 22/11/18 19:00
A dietary change could be a key to enhancing colon cancer treatment, a new study finds. Researchers found in cells and in mice that a low-protein diet blocked the nutrient signaling pathway that fires up a master regulator of cancer growth.
Scientists produce 'DNA virus vaccine' to fight DNA viruses
- ScienceDaily
- 22/11/18 19:00
Rutgers scientists have developed a new approach to stopping viral infections: a so-called live-attenuated, replication-defective DNA virus vaccine that uses a compound known as centanamycin to generate an altered virus for vaccine development.
Brain organoids reveal in detail the harms of prenatal alcohol exposure
- ScienceDaily
- 22/11/18 19:00
No amount of alcohol consumption is safe for a developing fetus. A new study presents in molecular detail how alcohol harms growth and functioning of developing brain organoids.
Novel AI blood test detects liver cancer
- ScienceDaily
- 22/11/18 17:48
A novel artificial intelligence blood testing technology has been used to successfully detect lung cancer in a 2021 study has now detected more than 80% of liver cancers in a new study of 724 people.
Newly developed gene classifier identifies risk of pre-breast cancer progression
- ScienceDaily
- 22/11/18 17:48
Researchers mapping a molecular atlas for ductal carcinoma in situ (DCIS) have made a major advance toward distinguishing whether the early pre-cancers in the breast will develop into invasive cancers or remain stable.
Scientists build nanoscale parapets, aqueducts, and other shapes
- ScienceDaily
- 22/11/18 17:48
Scientists have developed a new way to guide the self-assembly of a wide range of novel nanoscale structures using simple layered block copolymers as starting materials. The work could help guide the design of custom surface coatings with tailored optical, electronic, and mechanical properties for use in sensors, batteries, filters, and more.
