Highly efficient perovskite solar cells with enhanced stability and minimised lead leakage
While the power conversion efficiency of perovskite solar cells (PVSCs) has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the stability issue without compromising efficiency, paving the way for real-life application of perovskite photovoltaic technology.

Mirror-like photovoltaics get more electricity out of heat
New heat-harnessing 'solar' cells that reflect 99% of the energy they can't convert to electricity could help bring down the price of storing renewable energy as heat, as well as harvesting waste heat from exhaust pipes and chimneys.

The right formula for scaling production of promising material to decontaminate water
An international team of researchers have found a way to refine and reliably produce an unpredictable and hard-to-control material that could impact environmental conservation, energy and consumer electronics. The material, Molybdenum Disulfide (MoS2), holds tremendous potential for numerous applications in energy storage, water treatment, gas, chemical and light sensing.

Your cells look young for their age, compared to a chimp's
Many humans live to see their 80s, some even reach 100. But chimpanzees rarely make it past 50, despite sharing 99% of our genetic code. While modern medicine has added years to human lifespans, a study points to a more ancient explanation why humans are the long-lived primate. Part of the secret to human longevity may lie in chemical changes to our DNA that slowed the rate of aging after human ancestors diverged from chimps.

Male baboons with female friends live longer
Opposite-sex friendships can have non-romantic benefits. And not just for people, but for our primate cousins, too. A 35-year study of 542 baboons finds that males that have close female friends have higher rates of survival. Previous studies have assumed that males befriend females to protect their offspring, or to boost their chances of mating later on. But the new study points to an additional benefit: female friends may help them live a longer life.

Rochester researchers document an optical fiber beyond compare
A new anti-resonant hollow core optical fiber produces a thousand times less "noise" interfering with signals it transmits compared to the single-mode fibers now widely used. This is the lowest level ever recorded from interference caused by acoustic phonons arising from the glass in the fiber at room temperatures, researchers at the University of Rochester report.

VLBA makes first direct distance measurement to magnetar
Using the VLBA, astronomers have made the first direct geometric measurement of the distance to a magnetar. This precision measurement to one of the most magnetic objects in the Universe could help scientists determine if such objects are responsible for generating the mysterious Fast Radio Bursts.

Increasing the effectiveness of immunotherapy against skin cancer
Researchers at the University of Bern have discovered a mechanism in the body's own immune system which is responsible for the maturation and activation of immune cells. In the fight against skin cancer, the results have the potential to help immunotherapies succeed, even in patients for whom they have so far been ineffective.

New mathematical tool can select the best sensors for the job
In the 2019 Boeing 737 Max crash, the recovered black box from the aftermath hinted that a failed pressure sensor may have caused the ill-fated aircraft to nose dive. This incident and others have fueled a larger debate on sensor selection, number and placement to prevent the reoccurrence of such tragedies. Texas A&M University researchers have now developed a comprehensive mathematical framework that can help engineers make informed decisions about which sensors to use.

The acrobatic hydra shows off: How environmental cues can affect behavior
A duo from Columbia University and the Marine Biological Laboratory (MBL) has begun to crack the neural code behind Hydra's simplest behavior, called contraction bursts. The team found that the concentration of dissolved particles in the surrounding water affects the activity of a neural circuit in one of Hydra's nerve nets, which can trigger a specific set of muscle cells to contract the torso.

Algorithms uncover cancers' hidden genetic losses and gains
Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by Princeton computer scientists will allow researchers to more accurately identify these mutations in cancerous tissue, yielding a clearer picture of the evolution and spread of tumors than was previously possible.

Scientists sound alarm on plastic pollution
A new study shows that despite global commitments to address plastic pollution, growth in plastic waste, or 'plastics emissions' continues to outpace reduction. What's more, the study shows that even if governments around the world adhere to their ambitious commitments to curb plastic pollution, annual plastic emissions may increase more than six-fold by 2030.

Understanding the movement patterns of free-swimming marine snails
New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions. By using a high-speed stereophotogrammetry system, investigators were able to focus on how the shell shape, body geometry, and body size affect their swimming behavior from a fluid mechanics perspective, while image analysis and metabarcoding related swimming behaviors to night time and daytime vertical distributions.

Kang finds keys to control the 'driver of cancer's aggressiveness'
A dangerous protein named SNAI2 helps cancers metastasize and shields cancer from both the immune system and chemotherapy. Worse, SNAI2 is in a family of proteins that are notoriously hard to fight with drugs. But now Princeton University's Yibin Kang and his colleagues have found a way to use the cell's recycling system to control SNAI2, providing a new possibility for treatments.
