Heat Treatment May Make Chemotherapy More Effective

Posted by in categories: biotech/medical, chemistry

Summary: Heating up cancer cells as they are being targeted with chemotherapy appears to be a highly effective way of killing them off.

The study, published in the Journal of Materials Chemistry B, found that “loading” a chemotherapy drug on to tiny magnetic particles that can heat up the cancer cells at the same time as delivering the drug to them was up to 34% more effective at destroying the cancer cells than the chemotherapy drug without added heat.

Researchers fabricate arrays of atomically smooth iron-coated silicon pyramids with unusual magnetic properties

Posted by in categories: nanotechnology, transportation

Ultra-small integrated circuits have revolutionized mobile phones, home appliances, cars, and other everyday technologies. To further miniaturize electronics and enable advanced functions, circuits must be reliably fabricated in three dimensions. Achieving ultrafine 3D shape control by etching into silicon is difficult, because even atomic-scale damage reduces device performance. Researchers at Nara Institute of Science and Technology (NAIST) have published a new study in Crystal Growth and Design in which they etched silicon to adopt the shape of atomically smooth pyramids. Coating these silicon pyramids with a thin layer of iron imparted magnetic properties that until now were only theoretical.

NAIST researcher and senior author of the study Ken Hattori is widely published in the field of atomically controlled nanotechnology. One focus of Hattori’s research is in improving the functionality of -based technology.

“Silicon is the workhorse of modern electronics because it can act as a semiconductor or an insulator, and it’s an abundant element. However, future technological advances require atomically smooth device fabrication in three dimensions,” says Hattori.

Scientists Say Life Could Survive Inside Stars

The scientists even pointed to specific stars, like the erratic EPIC 249706694, that might be harboring such life, though once again they say they’re totally speculating. These theoretical organisms would survive by absorbing some of their star’s energy, so any star that dims faster than models predict could, theoretically, be serving as host.

“It is a fascinating thought that the universe may be packed with intelligent life that is so different from ours that we failed to recognize its existence,” study coauthor Eugene Chudnovsky told ScienceAlert.

Supercapacitors Challenge Batteries: Powerful Graphene Hybrid Material for Highly Efficient Energy Storage

Posted by in categories: chemistry, computing, mobile phones, sustainability, transportation

A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries.

Usually, energy storage is associated with batteries and accumulators that provide energy for electronic devices. However, in laptops, cameras, cellphones or vehicles, so-called supercapacitors are increasingly installed these days.

Unlike batteries they can quickly store large amounts of energy and put it out just as fast. If, for instance, a train brakes when entering the station, supercapacitors are storing the energy and provide it again when the train needs a lot of energy very quickly while starting up.

Study explores the effects of immune responses on the aging brain

Posted by in categories: biotech/medical, life extension, neuroscience

Has some interesting parts, might interest some.

(not sure how novel)


As human beings age, the functioning of organs gradually deteriorates. While countless past studies have investigated the effects of aging on the human body, brain and on cognition, the neural mechanisms and environmental factors that can accelerate or slow down these effects are not yet fully understood.

The Giant Magellan Telescope Will Revolutionize Our View and Understanding of the Universe

Posted by in category: space

The Giant Magellan Telescope will be one of the few super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed at the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2021.

The GMT is a segmented mirror telescope that employs seven of today’s largest stiff monolithic mirrors as segments. Six off-axis 8.4 meter segments surround a central on-axis segment, forming a single optical surface 24.5 meters in diameter, with a total collecting area of 368 square meters. Harvard University and the Smithsonian Institution are both members of the GMT project, which also includes Astronomy Australia Ltd., the Australian National University, the Carnegie Institution for Science, the Korea Astronomy and Space Science Institute, the São Paulo Research Foundation, the University of Texas at Austin, Texas A&M University, the University of Arizona, and the University of Chicago.

Edinburgh company generates electricity from gravity

Posted by in categories: energy, sustainability

An Edinburgh company that generates electricity from gravity — is getting noticed by investors, as an effective alternative to large batteries, so that renewable energy supply can be stored until there is demand. No need to go to the Congolese jungle to get hold of the raw materials for batteries.
