Scientists developing clean energy systems from micro-algae

October 9, 2007

An international consortium established by Associate Professor Ben Hankamer at The University of Queensland is developing a clean source of energy that could see some of our future fuel and possibly water needs being generated by solar-powered bioreactors and microalgae while absorbing CO2.

Scientists digitally mimic evolution to create novel proteins

May 10, 2016

SEWING method-ft

Here’s an innovative idea: create new proteins by simply “sewing” together pieces of existing proteins. That’s exactly what researchers at the University of North Carolina School of Medicine have done to design new “cellular machines” needed to understand and battle diseases.

Published today in the journal Science, the new technique, called SEWING, was inspired by natural evolutionary mechanisms that also recombine portions of the 100,000 different known… read more

Scientists discover largest structure in universe

October 27, 2003

Scientists have discovered the largest structure yet found in the universe, a “Great Wall” of galaxies 1.37 billion light-years long, according to an article in Science, Oct. 24, 2003.

This cosmic ribbon dwarfs anything seen before by more than 600 million light-years. The wall’s vastness pushes the limits of existing cosmological theories.

Scientists discover 21st century plague

November 24, 2008

Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans.

Brown rats, the biggest and most common rats in Europe, may now be carrying the bacteria.

Scientists discover a controller of brain circuits

December 29, 2009

A Johns Hopkins neuroscientist has found that semaphorin proteins regulate the number of synapses and their distribution in the part of the brain involved in conscious thought, which could have an impact on how scientists think about the early origins of autism, schizophrenia, epilepsy and other neurological disorders.

Scientists Discover a New Way to Slow Speed of Light

July 21, 2003

Researchers say they have slowed light in specially treated crystals of alexandrite and at room temperature. This could lead to a new generation of components to build optical and quantum computers and more-efficient optical communications systems.

Scientists discover a tangle of neurons that control aggression

February 10, 2011

In a tiny region buried deep in the brain, neurons that control two disparate behaviors — aggression and mating — are closely intertwined, Howard Hughes Medical Institute researchers have revealed. The study, conducted in mice, suggests that the association between these two classes of neurons may help to suppress aggressive behaviors during mating.

Scientists have long known that stimulating a particular region of the brain could trigger aggressive behavior.… read more

Scientists discover a way to reverse memory loss in ‘accidental breakthrough’

January 31, 2008

Toronto Western Hospital scientists have found in experiments with deep-brain stimulation that they caused a patient to experience vivid memories of an event that occurred 30 years earlier.

In the following weeks, and up to a year later, the memory of the 50-year-old patient improved. They are now experimenting with electrodes surgically implanted for treating Alzheimer’s patients.

Scientists discover atomic-resolution secret of high-speed brain signaling

Could lead to treatments for mental disorders
August 17, 2015

This illustration shows a protein complex at work in brain signaling. Its structure, which contains joined protein complexes known as SNARE and synaptotagmin-1, is shown in the foreground. This complex is responsible for the calcium-triggered release of neurotransmitters from our brain’s nerve cells in a process called synaptic vesicle fusion. The SNARE structure is shown in blue, red, and green, and synaptotagmin-1 is shown in orange. The background image shows electrical signals traveling through a neuron.

Stanford School of Medicine scientists have mapped the 3D atomic structure of a two-part protein complex that controls the release of signaling chemicals, called neurotransmitters, from brain cells in less than one-thousandth of a second.

The experiments were reported today (August 17) in the journal Nature. Performed at the Linac Coherent Light Source (LCLS) X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory, the experiments were built… read more

Scientists discover enzyme that could slow part of the aging process in astronauts and the elderly

New research suggests that the 5-lipoxygenase enzyme plays a key role in cell death induced by microgravity environments, and that inhibiting this enzyme will likely help prevent or lessen the severity of immune problems in astronauts caused by spaceflight.

And since space conditions create health problems that mimic the aging process on Earth, this discovery may also lead to therapeutics that extend lives by bolstering the immune systems of the… read more

Scientists discover exotic quantum state of matter

April 28, 2008

Princeton University scientists have found that one of the most intriguing phenomena in condensed-matter physics–known as the quantum Hall effect–can occur in nature in a way that no one has ever before seen.

Writing in the April 24 issue of Nature, the scientists report that they have recorded this exotic behavior of electrons in a bulk crystal of bismuth-antimony without any external magnetic field being present. The work, while… read more

Scientists discover first evidence of brain rewiring in children

December 10, 2009

Intensive instruction to improve reading skills in young children causes the brain to physically rewire itself, creating new white matter that improves communication within the brain, Carnegie Mellon University scientists have discovered, with implications for treating reading disabilities and other developmental disorders, including autism.

Scientists discover hidden code in DNA

December 16, 2013

A second code hiding within DNA has been discovered by University of Washington scientists, containing information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease.

Some scientists are skeptical about “hype” regarding the announcement.

Since the genetic code was deciphered in the 1960s, scientists have assumed that it was used exclusively to write… read more

Scientists discover how brain cells age

Newcastle University researchers say they have discovered how neurons age.

Experts previously identified the molecular pathway that reacts to cell damage and stems the cell’s ability to divide, known as cell senescence. However, in cells that do not have this ability to divide, such as neurons in the brain and elsewhere, little was understood of the aging process.

Now scientists at Newcastle University, led by Professorread more

Scientists discover how brain encodes vowel pronunciation

Discovery may hold key to restoring speech after paralysis
August 24, 2012

verbalizing_vowels

Scientists at UCLA and the Technion (Israel’s Institute of Technology) have unraveled how our brain cells encode the pronunciation of individual vowels in speech.

The discovery could lead to new technology that verbalizes the unspoken words of people paralyzed by injury or disease.

“We know that brain cells fire in a predictable way before we move our bodies,” said Dr. Itzhak Fried, a professor… read more
