Study: O&G companies reward US representatives who oppose environmental protections

A combined team of researchers from Yale University and the University of Cambridge has found that gas and oil companies reward U.S. lawmakers who oppose environmental protections by increasing campaign contributions. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of the money donated to politicians in the U.S. by gas and oil companies...

CO2 laser ablation leads a novel path to customized continuous fused silica surfaces

Fused silica is a significant material for numerous applications in optics and photonics owing to its excellent optical performance. The processing of fused silica with pulsed CO2 laser ablation offers the opportunity of converting an arbitrarily etched stepping structure into a continuous one. However, the achievement of continuous optical surfaces with the highest precision by laser-pulse...

Scientists invent lightweight liquid metal materials

Room temperature liquid metal, for example Gallium-based alloy, has high electrical and thermal conductivity, and excellent fluidity. They can be used in various application fields such as flexible electronics, wearable devices, biomedical practices, exoskeleton systems and soft robotics etc. However, components made by liquid metal may heavier than non-metal ones. The density of metal is larger...

This is how a channel is formed between two organelles

The channel through which two cell components exchange material appears to form at the edge of their contact surface, and not in the middle. This was discovered by the Leiden physical chemists Jelger Risselada and Edgar Blokhuis together with researchers from the University of Lausanne in Switzerland. They published their findings in The Journal of Physical Chemistry Letters on 20 February.

For lemurs, water holes are a matter of taste

It's 1 p.m. and you're only halfway through a six-hour hike, climbing in steep terrain under a 100° cloudless sky. Your water bottle is nearly empty, and you've heard the worst of this hike is yet to come.

Henneguya salminicola: Microscopic parasite has no mitochondrial DNA

An international team of researchers has found a creature with no mitochondrial DNA, making it the only known animal to exist without the need to breathe oxygen. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of Henneguya salminicola, a microscopic, parasitic member of the group Myxozoa and its unique physiology.

Tenerife coronavirus: 1,000 guests at hotel quarantined

H10 Costa Adeje Palace hotel on lockdown, as first case confirmed in mainland Spain Coronavirus outbreak – live updatesA thousand guests and staff at a hotel in Tenerife have been quarantined after an Italian man tested positive for the coronavirus, as Spain confirmed its fourth case of the virus.On Tuesday afternoon, the Catalan health department confirmed the region’s first recorded case...

Why do men kill their families? Here's what the research says

As the country mourns the horrific murders of Hannah Clarke and her three children, Aaliyah, Laianah and Trey at the hands of their father, many people are trying to make sense of what happened to them—and perhaps learn something to prevent it from happening again.

Want to help save wildlife after the fires? You can do it in your own backyard

People living in cities far from the unprecedented bushfires this summer may feel they can do little more to help beyond donating to organizations that support affected wildlife. But this is not necessarily the case: ten of the 113 top-priority threatened animal species most affected by the fires have populations in and around Australian cities and towns. Conserving these populations is now even...

New metabolic engineering strategy improves bioproduction of polymer raw materials

A research group, consisting of doctoral student Fujiwara Ryosuke, Associate Professor Tanaka Tsutomu (both of Kobe University's Graduate School of Engineering) and Research Scientist Noda Shuhei (RIKEN Center for Sustainable Resource Science), has succeeded in improving the yield of target chemical production from biomass. They achieved this through metabolically engineering the bacteria used in...

Study suggests that mangrove forests provide cause for conservation optimism

Southeast Asia has the greatest diversity of mangrove species in the world, and mangrove forests provide multiple ecosystem services upon which millions of people depend. Mangroves enhance fisheries by providing habitat for young fishes and offer coastal protection against storms and floods. They also store substantially higher densities of carbon, as compared to most other ecosystems globally,...

Radio waves detect particle showers in a block of plastic

When neutrinos crash into water molecules in the billion-plus tons of ice that make up the detector at the IceCube Neutrino Observatory in Antarctica, more than 5,000 sensors detect the light of subatomic particles produced by the collisions. But as one might expect, these grand-scale experiments don't come cheap.

Researchers find new reason Arctic is warming so fast

The Arctic has experienced the warming effects of global climate change faster than any other region on the planet. Scientists at the Scripps Institution of Oceanography have developed a new theory aided by computer simulations and observations that helps explain why this occurs.
