British soldiers successfully test drone killer radiowave weapon for first time

Posted by in categories: drones, energy

British soldiers have successfully trialled for the first time a game-changing weapon that can take down a swarm of drones using radio waves for less than the cost of a pack of mince pies.

The Radio Frequency Directed Energy Weapon (RFDEW) development system can detect, track and engage a range of threats across land, air and sea.

RFDEWs are capable of neutralising targets up to 1km away with near instant effect and at an estimated cost of 10p per shot fired, providing a cost-effective complement to traditional missile-base air defence systems.

Robots In Space: Hayabusa2 at Ryugu asteroid

Posted by in categories: robotics/AI, space

Journey into one of humanity’s most ambitious space missions as we explore JAXA’s groundbreaking Hayabusa2 mission to asteroid Ryugu! Discover how this remarkable spacecraft not only achieved the first successful deployment of rovers on an asteroid but also brought back precious samples that could reveal secrets about our solar system’s formation. From the dramatic touchdown on Ryugu’s surface to the revolutionary MASCOT and MINERVA rovers that hopped across its microgravity environment, this video breaks down the incredible technology and scientific discoveries from this historic asteroid sample return mission. Learn how these primitive asteroid samples are reshaping our understanding of the early solar system and what this means for future space exploration.

A NASA Spacecraft Will ‘Touch’ the Sun on Christmas Eve, Flying Closer to the Star Than Any Probe Before

Posted by in category: space

Merry Christmas Holidays Everyone!


The holiday season is a busy time for humankind’s sun-surfing spacecraft. This Christmas Eve, the Parker Solar Probe will be going where no probe has gone before: a mere 3.8 million miles from the sun’s surface.

Observations detect young and energetic pulsar in a supernova remnant

Posted by in category: cosmology

An international team of astronomers has reported the discovery of a new pulsar, which received the designation PSR J1631–4722. The newfound pulsar, which is young and energetic, turns out to be associated with a supernova remnant known as SNR G336.7+0.5. The finding was detailed in a research paper published Dec. 16 on the arXiv pre-print server.

Pulsars are highly magnetized, rotating emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission; however, some of them are also observed via optical, X-ray and gamma-ray telescopes.

Pulsars directly associated with known remnants (SNRs) are generally rare as only dozens of such objects have been discovered to date. Finding these associations is crucial for astronomers as they could shed more light on pulsar formation history and supernova explosion mechanisms.

Tidally driven remelting around 4.35 billion years ago indicates the Moon is old

Posted by in categories: evolution, space

Lunar rock and zircon ages were reset by a remelting event driven by the Moon’s orbital evolution, reconciling existing discrepancies in estimates for the formation time of the Moon and the crystallization time of its magma ocean.

Tiny, wireless antennas use light to monitor cellular communication

Posted by in categories: biotech/medical, neuroscience

Monitoring electrical signals in biological systems helps scientists understand how cells communicate, which can aid in the diagnosis and treatment of conditions like arrhythmia and Alzheimer’s.

But devices that record electrical signals in cell cultures and other liquid environments often use wires to connect each electrode on the device to its respective amplifier. Because only so many wires can be connected to the device, this restricts the number of recording sites, limiting the information that can be collected from cells.

MIT researchers have now developed a biosensing technique that eliminates the need for wires. Instead, tiny, wireless antennas use light to detect minute electrical signals.
