Bioadhesive, wirelessly-powered implant emitting light to kill cancer cells

Scientists from Waseda University, the National Defense Medical College, and the Japan Science and Technology Agency developed a new bioadhesive, wirelessly-powered light-emitting device which could better treat cancers in delicate organs. Conventional photodynamic therapy induces cancer cell death by using photosensitizing agents, which localize in tumors and activate with exposure ... Read More »

Renewable energy sources: All-in-one light-driven water splitting

Solar-powered water splitting is a promising means of generating clean and storable energy. A novel catalyst based on semiconductor nanoparticles has now been shown to facilitate all the reactions needed for ‘artificial photosynthesis’. In the light of global climate change, there is an urgent need to develop efficient ways of ... Read More »

Little star sheds light on young planets

Early in 2017, Assistant Professor Yoko Oya gave graduate student Yuki Okoda some recent complex data on a nearby star with which she could begin her Ph.D. Little did she realize that what she would find could unlock not only the secrets of how planets form but possibly her career ... Read More »

The spotlight of attention is more like a strobe light

You don’t focus as well as you think you do. That’s the fundamental finding of a team of researchers from Princeton University and the University of California-Berkeley who studied monkeys and humans and discovered that attention pulses in and out four times per second. “Our subjective experience of the visual ...

Making light work of quantum computing

Light may be the missing ingredient in making usable quantum silicon computer chips, according to an international study featuring a University of Queensland researcher. The team has engineered a silicon chip that can guide single particles of light — photons — along optical tracks, encoding and processing quantum-bits of information ... Read More »

Light from ancient quasars helps confirm quantum entanglement

Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in a way that defies the rules of classical physics. Take, ... Read More »

Indian scientists discover exoplanet 600 light years away

The discovery was made by measuring the mass of the planet using the indigenously designed “PRL Advance Radial-velocity Abu-sky Search” (PARAS) spectrograph integrated with 1.2m Telescope at PRL’s Gurushikhar Observatory in Mount Abu. The discovery is important for understanding the formation mechanism of sub-Saturn and super-Neptune like planets that are ... Read More »

Rain batters northeast, IMD forecasts light showers in Delhi today

The India Meteorological Department daily report predicted light rainfall today in Delhi, reeling under a haze of dust brought by winds from Rajasthan which has raised the air pollution level to “severe”. It said the monsoon was hovering over Maharashtra in the west and parts of Odisha, West Bengal and ... Read More »

Dust storm, light rain in Delhi

The weatherman said light rain was witnessed in many areas. The dust storm pushed the temperature down by a few notches on what was a sultry day. The city recorded a high of 40.5 degrees Celsius and a low of 30 degrees Celsius, according to the MeT office. The humidity ... Read More »

Light rainfall in parts of Udaipur & Rajasthan

Udaipur : Light rainfall occurred at isolated places in Udaipur and Jaipur today while the weather remained dry in rest of the state. The lack of rainfall led to rise in mercury by a few degrees in parts of the state, the MeT Department said.
