A row-bot that loves dirty water

Researchers at the University of Bristol have developed a row-bot that can operate indefinitely in remote locations by harnessing energy from dirty water. The robot's bio-inspired mechanism allows it to feed on nutrient-rich water, generating electricity through microbial fuel cells.

When did the Andes mountains form?

The Andes mountain chain was formed 14 million years ago, according to new research from the University of Bristol. The study used a novel method based on cosmic rays to determine the age of large boulders in the western margin of the Andes.

A 'nervous system' for ant colonies?

Researchers studied ant colonies subjected to simulated predator attacks, revealing differentiated responses based on location. The results show that ants respond appropriately to damage, similar to single organisms, with colony-wide responses triggered by loss of workers within the nest.

Developing a nanoscale 'clutch'

Researchers have created a model microscopic system to demonstrate torque transmission at the nanoscale, overcoming thermal fluctuations and energy dissipation. The device uses colloidal particles to transfer rotational motion, revealing new transmission phenomena not seen in macroscopic machines.

Squid inspires camouflaging smart materials

Researchers at the University of Bristol have designed a smart materials system inspired by biological chromatophores, mimicking squid skin's camouflage abilities. The artificial skin, made from electroactive dielectric elastomer, can effectively copy biological patterns and even mimic complex dynamic patterning seen in real cephalopods.

Finding hope in the dark

Researchers have identified a gene, PRDM8, linked to early loss of night vision in animal models. Gene therapy for Leber's congenital amaurosis shows promising results, but temporary improvements are seen.

Microscopic sonic screwdriver invented

Researchers at University of Bristol invent a microscopic acoustic vortice that can grip and spin small particles, opening new possibilities for biological cell sorting and water purification. The device uses sound waves to rotate particles, with larger objects being drawn into the core and spinning at high speeds.

How climate science denial affects the scientific community

A new study from the University of Bristol argues that climate science denial is seeping into the scientific community's discussion of climate change, causing them to overemphasize scientific uncertainty. This 'seepage' of contrarian claims has led scientists to downplay the degree of threat and undercommunicate knowledge, despite know...

Unexplained gap in global emissions of potent greenhouse gases resolved

Researchers at the University of Bristol have resolved an unexplained gap in global emissions reports, finding that developing countries are significantly contributing to the issue. The study used atmospheric measurements and models to evaluate reported HFC emissions and found inconsistencies in reporting, with some gases being over- o...

Sexing Stegosaurus

A recent study by Evan Saitta found that Stegosaurus had two types of plates: tall and wide. Contrary to previous claims, these were not separate species or ages, but rather males and females. The plates likely played a role in attracting mates and displaying sex.

Oldest fossils controversy resolved

New analysis reveals 'Apex chert microfossils' are not evidence of ancient life but rather peculiarly shaped minerals. Researchers used high-spatial resolution data to map chemical composition and morphology at the sub-micrometre scale, clearing up a long-standing debate about Earth's earliest fossils.

How big data can be used to understand major events

Academics from the University of Bristol's Intelligent Systems Laboratory used big data to analyze mass media coverage of the 2012 US presidential election. The study found that the media focused more frequently on positive statements about the Democrats, while the Republicans were often portrayed in a negative light. Key issues covere...

Understanding the copper heart of volcanoes

A team of scientists from the University of Bristol has discovered a two-step process for porphyry copper formation, which could revolutionize the search for new copper deposits. The study reveals that salt-rich fluids and sulphur-rich gases interact to form copper ore, providing insights into the formation of global copper reserves.
