NASA’s Curiosity rover’s Sample Analysis at Mars (SAM) instrument has likely relayed some provocative findings, Space.com reports.

John Grotzinger, lead mission investigator for the Curiosity rover, set the rumors in motion during an interview with NPR last week, saying, “We’re getting data from SAM … this data is gonna be one for the history books. It’s looking really good.”

Scientists squeeze more than 1,000 cores onto computer chip

January 5, 2011

Xilinx Virtex FPGA chip

Scientists at the University of Glasgow and the University of Massachusetts Lowell have created an ultra-fast 1,000-core computer processor.

They used a field programmable gate array (FPGA) chip, which can be configured into specific circuits by the user,  enabling the researchers to divide up the transistors within the chip into small groups and ask each to perform a different task.

By creating more than 1,000 mini-circuits within the… read more

Scientists Strive to Map the Shape-Shifting Net

March 2, 2010

The shape of the Internet is changing rapidly, driven by a variety of factors, including content delivery networks that have pushed both data and applications to the edge of the network; the growing popularity of smartphones, leading to the emergence of the wireless Internet; the explosion of streaming video as the Internet’s predominant data type; and “dark networks,” private channels created to move information more cheaply and efficiently within a… read more

Scientists Study How to Stack the Deck for Organic Solar Power

July 29, 2009

National Institute of Standards and Technology scientists have developed a new class of economically viable solar power cells using organic photovoltaics.

Scientists successfully awaken sleeping stem cells

March 19, 2008

Scientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells.

The discovery offers new hope to victims of diseases that harm the retina, such as macular degeneration and retinitis pigmentosa.

Scientists successfully edit human immune-system T cells

New CRISPR research has implications for autoimmune diseases, AIDS, and cancer
July 29, 2015

Cas9 edit

In a project led by investigators at UC San Francisco , scientists have devised a new strategy to precisely modify human immune-system T cells, using the popular genome-editing system known as CRISPR/Cas9. T cells play important roles in a wide range of diseases, from diabetes to AIDS to cancer, so this achievement provides a path toward CRISPR/Cas9-based therapies for many serious health problems, the scientists say.… read more

Scientists suggest certain genes boost chances for distributing variety of traits, drive evolution

December 15, 2009

Gene variants or alleles that don’t themselves directly affect the inherited characteristics of an organism but increase random distribution of characteristics may be a significant force in evolution, driving the development of the wide variety of traits — from height to skin tone to disease risk — seen in modern populations, Johns Hopkins scientists suggest.

In standard Darwinian theory, characteristics that affect an organism’s ability to adapt and survive… read more

Scientists suggest that cancer is purely man-made

October 15, 2010

Cancer is a modern, man-made disease caused by environmental factors such as pollution and diet, a study by University of Manchester scientists has strongly suggested.

A study of remains and literature from ancient Egypt and Greece and earlier periods — carried out at the University of Manchester’s KNH Centre for Biomedical Egyptology and published in Nature — includes the first histological diagnosis of cancer in an Egyptian mummy.… read more

Scientists take important step toward the proverbial fountain of youth

December 23, 2009

Reduced glucose caused normal lung cells to have a higher activity of the gene that dictates the level of telomerase (an enzyme that extends their lifespan) and lower activity of a gene that slows their growth, University of Alabama researchers have found.

Scientists Take Step Toward Single-Molecule Switches

June 22, 2001
Single molecule in ON and OFF states

Computers of the future may have components that function based on the action of single molecules, according to a paper by researchers at Penn State and Rice University published in the June 22 edition of Science.

Conformational changes — which happen when molecules alter their arrangement by rotation of their atoms around a single bond, effectively changing shape by moving or turning — determine how and when… read more

Scientists threatened for ‘climate denial’

March 13, 2007

Scientists who questioned mankind’s impact on climate change have received death threats and claim to have been shunned by the scientific community.

They say the debate on global warming has been “hijacked” by a powerful alliance of politicians, scientists and environmentalists who have stifled all questioning about the true environmental impact of carbon dioxide emissions.

Richard Lindzen, professor of Atmospheric Science at Massachusetts Institute of Technology recently claimed:… read more

Scientists time-reverse developed stem cells to make them ‘embryonic’ again

May help avoid ethically controversial use of human embryos for research and support other research goals
March 24, 2016

Stem-Cells-Before-and-After-Treatment-ft

University of Michigan Medical School researchers have discovered a way to convert mouse stem cells (taken from an embryo) that have  become “primed” (reached the stage where they can  differentiate, or develop into every specialized cell in the body) to a “naïve” (unspecialized) state by simply adding a drug.

This breakthrough has the potential to one day allow researchers to avoid the ethically controversial use ofread more

Scientists to build ‘brain box’

July 19, 2006

The “brain box,” being built by University of Manchester scientists, will use large numbers of microprocessors to model the way networks of neurons interact.

Scientists to build robot society

April 26, 2007

Scientists in Scotland have announced plans to create a “robot village” in an effort to learn how different cultures emerge in society.

The University of Abertay’s four-year study will feature about 60 miniature robots who will be organized into groups and programmed to interact. The project team plans to observe the robots to see how they behave together.

Scientists to explore nano advancements in DNA sequencing

October 4, 2007

UC Irvine’s Henry Samueli School of Engineering has been awarded $2.18 million to blend traditional DNA sequencing techniques with cutting-edge nanotechnology to develop a faster and less costly method of DNA sequencing and make it a routine part of health care.
