Astronomers may have seen the light from two black holes smashing into one another for the first time ever.
Black holes are completely dark and therefore invisible to light-detecting telescopes. So far, the only way astronomers have been able to “observe” black holes colliding is by detecting the resulting gravitational waves.
On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks.
The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.
One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.
Summary: Entrainment can safely manipulate brain waves to induce improvements in memory, a new study reveals.

The brain is made of millions of cells called neurons, that send electrical messages to talk to each other in patterns of vertical electric activity called oscillations. By inducing them first, then finding the amplitude of the specific brain waves is improved during memory, ultimately memory performance itself is boosted. Once introduced, what if a person can boost the speed of these oscillations to improve memory? A university study in a journal for adolescents may show we can.
An ink made using engineered bacterial cells can be 3D-printed into structures that release anti-cancer drugs or capture toxins from the environment.
The microbial ink is the first printable gel to be made entirely from proteins produced by E.coli cells, without the addition of other polymers.
“This is the first of its kind… a living ink that can respond to the environment. We have repurposed the matrix that these bacteria normally utilise as a shielding material to form a bio-ink,” says Avinash Manjula-Basavanna at the Massachusetts Institute of Technology in Boston.
The misconception is that electrons carry potential energy around a complete conducting loop, transferring their energy to the load. This video was sponsored by Caséta by Lutron.

Architecture firm Skidmore, Owings & Merrill (SOM) has presented ‘Urban Sequoia’ – a concept for transforming the built environment into a network for absorbing carbon.
Urban Aeronautics, the Israel-based aerospace company behind the world’s first compact, wingless electric vertical takeoff, and landing (eVTOL) vehicle, is getting closer to turning its groundbreaking concept into reality. The company said it has raised the first $10 million of a $100 million funding round this week towards CityHawk from private investors in the US, Brazil, and Israel.
According to the company, the car-sized, six-seater CityHawk has more in common with birds than with nearly every other eVTOL prototype in existence. With a distinct, wingless exterior and patented fully-enclosed Fancraft rotor system, the CityHawk is mainly designed for commercial air charters and emergency medical services (EMS). It will be fueled by hydrogen, the most sustainable technology in development today. This means it must be able to conduct multiple trips within a city per day with zero emissions and minimal noise.
An innovative Fancraft technology is based on dual enclosed, ducted rotors with a variable pitch for thrust control, which enable uncompromised stability even in strong winds and turbulence during takeoff, hovering, and landing. The enclosed structure also results in minimal noise, both inside the cabin and outside.
