150901120805. New way to store solar energy could lead to more common solar cell usage. Researchers at Missouri University of Science and Technology have developed a relatively inexpensive and simple way to split water into hydrogen and oxygen through a new electrodeposition method.
The method produces highly efficient solar cells that can gather solar energy for use as fuel. The research, sponsored by the U.S. Department of Energy, could lead to a sizable increase in the amount of hydrogen available for fuel usage. The Missouri S&T researchers describe their full method in a paper published on the website of the journal Nature Materials. Tiny carbon-capturing motors may help tackle rising carbon dioxide levels. Machines that are much smaller than the width of a human hair could one day help clean up carbon dioxide pollution in the oceans.
Nanoengineers at the University of California, San Diego have designed enzyme-functionalized micromotors that rapidly zoom around in water, remove carbon dioxide and convert it into a usable solid form. The proof of concept study represents a promising route to mitigate the buildup of carbon dioxide, a major greenhouse gas in the environment, said researchers. The team, led by distinguished nanoengineering professor and chair Joseph Wang, published the work this month in the journal Angewandte Chemie. "We're excited about the possibility of using these micromotors to combat ocean acidification and global warming," said Virendra V.
Small-scale nuclear fusion may be a new energy source. Fusion energy may soon be used in small-scale power stations.
This means producing environmentally friendly heating and electricity at a low cost from fuel found in water. Both heating generators and generators for electricity could be developed within a few years, according to research that has primarily been conducted at the University of Gothenburg. Nuclear fusion is a process whereby atomic nuclei melt together and release energy. New Species Of Human Discovered In South Africa. Brace yourself: this discovery is huge.
So huge that its profound implications will shake up our very own family tree. The University of Witwatersrand, in collaboration with National Geographic, is proud to announce a remarkable story of human heritage. Scientists Develop Ice Cream That Doesn't Melt In The Heat. Frantically devouring your ice cream in hot weather as it starts to drip on your hand could soon be a thing of the past.
Scientists have developed a way to keep ice cream frozen for longer in high temperatures, helping it retain its smooth texture. The product could be available to consumers in three to five years. The breakthrough comes in the form of a naturally occurring protein called BsIA that can bind together air, fat and water. The protein is found in so-called “friendly bacteria” and is already part of the food chain. A Guide to Self-Care for People with Anxiety. [The image features a metal case, presumably a first aid kit, with the words “SELF CARE” on top.]
Holy anxiety, batman. If there’s one thing readers want to hear more about, it’s my experiences with anxiety — namely, how I cope with it. It seems like a lot of us are still trying to navigate this tricky condition. Therapy and medication can help, but a lot of how I manage my anxiety is based on a regular, consistent practice of self-care. I think that self-care — defined as intentional actions taken to improve one’s sense of well-being — has made a significant difference in my overall mood, and has been especially helpful in dealing with my anxiety. Photographer Captures Bee Peeing Mid-Flight. Scientists Accidentally Produce An Entirely New Type Of Glass. Glass is, by nature, random.
It is created by melting several minerals together at unfathomably high temperatures. Glass has a haphazard, disorganized structure, like a liquid frozen in time. However, by some happy accident, some scientists have created glass with a regular molecular pattern. The first inkling the scientists had that something was different about the glass they'd created came from some consistent peaks in their spectroscopic data.
Five Disturbing Things You Didn't Know About Forensic "Science" Last week, The Washington Post revealed that in 268 trials dating back to 1972, 26 out of 28 examiners within the FBI Laboratory’s microscopic hair comparison unit “overstated forensic matches in a way that favored prosecutors in more than 95 percent” of the cases.
These included cases where 14 people have since been either executed or died in prison. The hair analysis review — the largest-ever post-conviction review of questionable forensic evidence by the FBI — has been ongoing since 2012. Exclusive: New Study Shows Accuracy Of Fingerprint Analysis. Follow CBSMIAMI.COM: Facebook | Twitter MIAMI (CBSMiami) — You’ve likely seen crime scene investigators working their magic, dusting charcoal carbon powder and lifting fingerprints to use in criminal investigations.
Once the crime scene techs wrap up, a team of fingerprint examiners go to work identifying the only person in the world who matches that print. In the Miami-Dade Police crime lab, examiner Brian Cerchiai eyeballs fingerprint cards, but he and his team also match prints with the help of computer programs, that magnify the print helping them look at the details of the ridges. Click here to watch Natalia Zea’s report. Fingerprints: Not a Gold Standard. Fingerprints: Not a Gold Standard A few judges are showing signs of skepticism, and it’s about time.
In January 2002, Judge Louis Pollack made headlines with a surprising ruling on the admissibility of fingerprints. In United States v. Llera Plaza, the distinguished judge and former academic issued a lengthy opinion that concluded, essentially, that fingerprint identification was not a legitimate form of scientific evidence. Reliability-of-Fingerprint-Evidence. As a general proposition, fingerprint experts believe that fingerprint patterns never change and are unique to each individual.
For this reason, state and federal judges do not usually question their evidentiary validity. Juries typically agree when such evidence suggests an individual is guilty of committing a crime. Accuracy and reliability of forensic latent fingerprint decisions. Piezoelectricity. Crystals which acquire a charge when compressed, twisted or distorted are said to be piezoelectric. This provides a convenient transducer effect between electrical and mechanical oscillations.
Quartz demonstrates this property and is extremely stable. Piezoelectricity. A piezoelectric system (without contact tabs) Piezoelectricity is found in useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultrafine focusing of optical assemblies. It is also the basis of a number of scientific instrumental techniques with atomic resolution, the scanning probe microscopies such as STM, AFM, MTA, SNOM, etc., and everyday uses such as acting as the ignition source for cigarette lighters and push-start propane barbecues. Staring Into Someone's Eyes For 10 Minutes Can Alter Your Consciousness. Forget LSD: eyes are the new high. Of course, we’re not talking about consuming them, but rather staring intensely into a pair for a prolonged period of time. Apparently, this can make people enter into an altered state of consciousness.
This intriguing discovery was made by vision researcher Giovanni Caputo from the University of Urbino in Italy, but it isn’t his first staring contest study. A few years ago, the scientist recruited 50 volunteers and got them to gaze upon their reflections in a mirror for 10 minutes in a dimly lit room. Theconversation. For most of the common cancers, a major cause has been identified: smoking causes 90% of lung cancer worldwide, hepatitis viruses cause most liver cancer, H pylori bacteria causes stomach cancer, Human papillomavirus causes almost all cases of cervical cancer, colon cancer is largely explained by physical activity, diet and family history. But for breast cancer, there is no smoking gun. It is almost unique among the common cancers of the world in that there is not a known major cause; there is no consensus among experts that proof of a major cause has been identified. One step closer to an artificial nerve cell. Scientists Create Artificial Neuron that Functions Like the Real Thing.
Recording The Entire Nervous System In Real Time Will Unlock Secrets Of The Brain. There are around 100 billion neurons in the human brain, each connected to hundreds of neighbours. Analysing the link between neural activity in the brain, and the behaviour that causes it, could shed light on both areas. Shift Work Causes Breast Cancer In Mice, According To A New Study – So What Does This Mean For Humans?
