Halide perovskite solar cells hold promise as the next generation of solar cell technologies, but while researchers have developed techniques for improving their material characteristics, nobody understood why these techniques worked. New research sheds light on the science behind these engineering solutions and paves the way for developing more efficient halide perovskite solar cells.

Autonomous boats can target and latch onto each other
The city of Amsterdam envisions a future where fleets of autonomous boats cruise its many canals to transport goods and people, collect trash, or self-assemble into floating stages and bridges. To further that vision, MIT researchers have given new capabilities to their fleet of robotic boats—which are being developed as part of an ongoing project—that lets them target and clasp onto each other, and keep trying if they fail.

Proteasome inhibitors show promise for drug-resistant malaria
Proteasome inhibitors have significant promise as components of novel combination therapies to treat multidrug-resistant malaria, according to a study published June 6 in the open-access journal PLOS Pathogens by David Fidock, Caroline Ng, and Barbara Stokes of Columbia University Irving Medical Center, Matthew Bogyo of Stanford University School of Medicine, and colleagues.

Lab technology provides clarity amid Hawaiian water contamination concerns
One of the first things that comes to mind when you think of Hawaii are warm, tropical beaches with inviting, clear water. In fact, favorable beach water quality is the lifeblood for Hawaii's $18 billion annual tourist industry, the largest single contributor to the state's economy. So, it comes as no surprise that Hawaii water officials continuously monitor for sources of contamination that could threaten their main attraction.

Scientists recreate blood-brain barrier defect outside the body
Scientists can't make a living copy of your brain outside your body. That's the stuff of science fiction. But in a new study, they recreated a critical brain component, the blood-brain barrier, that functioned as it would in the individual who provided the cells to make it. Their achievement—detailed in a study published today in the peer-reviewed journal Cell Stem Cell—provides a new way to make discoveries about brain disorders and, potentially, predict which drugs will work best for an individual patient.

Rhythmic control of 'brain waves' can boost memory: study
Controlling the frequency of 'brain waves' could help to improve people's recall of memories and potentially provide a key to unlock conditions such as Alzheimer's disease, according to a new article.

The universal beauty of the mountains can be seen in graphs
Mountains have character. The continuous gentle, wavy hills and wide valleys of the Carpathians, Appalachians or lower parts of the Alps contrast strongly with the soaring peaks, ragged ridges and deep ravines of the high Tatra mountains and Pyrenees, which are, in turn, different from the inaccessible, snow-covered Himalayan or Andean giants, along whose slopes flow long tongues of glaciers instead of water. Beneath this great diversity, however, lies a surprisingly similar structure.

Evolving neural networks with a linear growth in their behavior complexity
Evolutionary algorithms (EAs) are designed to replicate the behavior and evolution of biological organisms while solving computing problems. In recent years, many researchers have developed EAs and used them to tackle a variety of optimization tasks.

Drug makes tumors more susceptible to chemo
Many chemotherapy drugs kill cancer cells by severely damaging their DNA. However, some tumors can withstand this damage by relying on a DNA repair pathway that not only allows them to survive, but also introduces mutations that helps cells become resistant to future treatment.

Protecting our energy infrastructure from cyberattack
Almost every day, news headlines announce another security breach and the theft of credit card numbers and other personal information. While having one's credit card stolen can be annoying and unsettling, a far more significant, yet less recognized, concern is the security of physical infrastructure, including energy systems.

Fussy, hungry, or in pain? Scientists create an AI tool to tell babies' cries apart
Every parent knows the frustration of responding to a baby's cries, wondering if their child is hungry, wet, tired, in need of a hug, or perhaps even in pain. A group of researchers in U.S. has devised a new artificial intelligence method that can identify and distinguish between normal cry signals and abnormal ones, such as those resulting from an underlying illness. The method, based on a cry language recognition algorithm, promises to be useful to parents at home as well as in healthcare settings, as doctors may use it to discern cries among sick children.

Video streaming framework allows users to download content collaboratively
Sharing a streaming video or watching the big game on a single electronic device can lead to a big fight: whose data plan is going to be used up for the event? Purdue University researchers have come up with technology that could open a new door for video streaming.

A home-based weight management program benefits both children and parents
Obese children are four times more likely to become obese adults making childhood obesity a significant health threat. A new study in the Journal of Nutrition Education and Behavior found the Developing Relationships that Include Values of Eating and Exercise (DRIVE) curriculum mitigated weight gain in at-risk children as well as prompting their parents to lose weight.

Researchers try to recreate human-like thinking in machines
Researchers at Oxford University have recently tried to recreate human thinking patterns in machines, using a language guided imagination (LGI) network. Their method, outlined in a paper pre-published on arXiv, could inform the development of artificial intelligence that is capable of human-like thinking, which entails a goal-directed flow of mental ideas guided by language.

Floating power plants
Paper, tin cans, glass—the world recycles as much as possible. So why not declare the greenhouse gas carbon dioxide (CO2) a recycling product as well? Liquid fuels based on carbon will continue to play an important role in the future—despite international efforts to reduce them. So it seems sensible to recover the CO2 exhaust from the environment and use it again.
