Hubble Captures a Mirrored Galaxy

Posted by in category: space

This intriguing observation from the NASA/ESA Hubble Space Telescope shows a gravitationally lensed galaxy with the long-winded identification SGAS J143845+145407. Gravitational lensing has resulted in a mirror image of the galaxy near the center of this image, creating a captivating centerpiece. A third distorted image of the galaxy appears as a bridge between them.

Gravitational lensing occurs when the mass of an enormous celestial body – such as a galaxy cluster – curves spacetime and causes the path of light from distant objects to visibly bend around it, as if by a lens. Appropriately, the body causing the light to curve is called a gravitational lens, and the distorted background object is referred to as being “lensed.” Gravitational lensing can result in multiple images of the original galaxy, as seen in this image, or in the background object appearing as a distorted arc or even a ring. Another important consequence of this lensing distortion is magnification, allowing astronomers to observe objects that would otherwise be too far away or be too faint to see.

The nickel crystal that catalysed collaboration

Posted by in category: chemistry

An apparent scooping turned into something much more valuable.

Before starting their weekend, Rosie Somerville and Marina Pérez-Jiménez decided to quickly check the latest literature. A few minutes later, the lab WhatsApp group was on fire. After months of arduous work on different organometallic complexes, some of them had just been published. What now?

Very often, researchers across the world work on similar developments without knowing about each other’s results. The latest recipients of the Nobel prize for chemistry, Benjamin List and Dave MacMillan, independently developed organocatalysis. But sometimes the science hall of fame works on a first-come, first-served basis. What if someone scoops the discovery?

Physicists harness quantum “time reversal” to measure vibrating atoms

Posted by in categories: cosmology, particle physics, quantum physics

MIT physicists have significantly amplified quantum changes in atomic vibrations, allowing them to exclude noise from the classical world. This advance may allow them to measure these atomic oscillations, and how they evolve over time, and ultimately hone the precision of atomic clocks and of quantum sensors for detecting dark matter or gravitational waves.

Huge jellyfish swarm surrounds boat in Israel

Posted by in categories: climatology, sustainability

Mesmerising aerial footage has captured a huge swarm of jellyfish off the coast of Israel.

The country’s marine authorities were inspecting the waters of Haifa Bay during the annual jellyfish migration, when its boat was surrounded.

Israel Parks and Nature Authority said that pollution and climate change are increasing the intensity of the jellyfish swarms.

Energy Harvester Produces Power from Local Environment, Eliminating Batteries in Wireless Sensors

Posted by in categories: robotics/AI, transportation

Advances in low power technology are making it easier to create wireless sensor networks in a wide range of applications, from remote sensing to HVAC monitoring, asset tracking and industrial automation. The problem is that even wireless sensors require batteries that must be regularly replaced—a costly and cumbersome maintenance project. A better wireless power solution would be to harvest ambient mechanical, thermal or electromagnetic energy from the sensor’s local environment.

Typically, harvestable ambient power is on the order of tens of microwatts, so energy harvesting requires careful power management in order to successfully capture microwatts of ambient power and store it in a useable energy reservoir. One common form of ambient energy is mechanical vibration energy, which can be caused by motors running in a factory, airflow across a fan blade or even by a moving vehicle. A piezoelectric transducer can be used to convert these forms of vibration energy into electrical energy, which in turn can be used to power circuitry.

WHO declares rapidly spreading monkeypox outbreak a global health emergency

Posted by in categories: biotech/medical, health

Tedros said the risk posed by monkeypox is moderate globally, but the threat is high in Europe. There’s clearly a risk that the virus will continue to spread around the world, he said, though it’s unlikely to disrupt global trade or travel right now.

In early May, the United Kingdom reported a case of monkeypox in a person who recently returned from travel to Nigeria. Several days later, the U.K. reported three more cases of monkeypox in people who appeared to have become infected locally. Other European nations, Canada and the U.S. then also began confirming cases. It’s unclear where the outbreak actually began.

The WHO last issued a global health emergency in January 2020 in response to the Covid-19 outbreak and two months later declared it a pandemic. The WHO has no official process to declare a pandemic under its organizational laws, which means the term is loosely defined. In 2020, the agency declared Covid a pandemic in an effort to warn complacent governments about the “alarming levels of spread and severity” of the virus.
