Scientists release most accurate simulation of the universe to date

September 30, 2011

Bolshoi High Res

The Bolshoi supercomputer simulation, announced Thursday, is the most accurate and detailed large cosmological simulation run to date, giving physicists and astronomers a powerful new tool for understanding such cosmic mysteries as galaxy formation, dark matter, and dark energy.

The simulation traces the evolution of the large-scale structure of the universe, including the evolution and distribution of the dark matter halos, in which galaxies coalesced… read more

Scientists Remotely Control Neurons and Animal Behavior

July 7, 2010


Clusters of heated, magnetic nanoparticles targeted to cell membranes can remotely control ion channels, neurons and even animal behavior, according to a paper published by University at Buffalo physicists in Nature Nanotechnology.

The research could have broad application, potentially resulting in innovative cancer treatments that remotely manipulate selected proteins or cells in specific tissues, or improved diabetes therapies that remotely stimulate pancreatic cells to release insulin.… read more

Scientists Report a Crucial Gain in Growing Stem Cells

January 3, 2006

Scientists at a laboratory affiliated with the University of Wisconsin have developed a stem-cell culture medium free of animal cells and used it to derive two new human embryonic stem-cell lines.

The work is considered a crucial step in stem-cell research because it will allow growth of these cells without using animal products that can harbor viruses and other potential sources of problems.

Scientists Report Evidence of Saltwater Pools on Mars

March 25, 2004

Mars was once a much warmer, wetter place, with pools of saltwater that sometimes flowed across the surface, scientists reported Tuesday. It was the first concrete evidence that water might have flowed on the Martian surface, and it provided new hints that life may have existed there.

Scientists Report Gains in Knowledge of Bacterium

October 24, 2001

Scientists reported two major advances yesterday in their understanding of the anthrax bacterium — discoveries that could lead to the development of drugs custom-designed to interfere with the anthrax toxin at different stages of its operation.

Scientists from Harvard Medical School and the University of Wisconsin said that after a decade’s search they had found the receptor protein on the surface of cells that was targeted by the anthrax… read more

Scientists report partial reversal of age-related degeneration in aged mice

November 30, 2010

Scientists at Dana-Farber Cancer Institute say they have for the first time partially reversed age-related degeneration in mice, resulting in new growth of the brain and testes, improved fertility, and the return of a lost cognitive function.

In a report posted online by the journal Nature in advance of print publication, researchers led by Ronald A. DePinho, MD, said they achieved the milestone in aging science by engineering… read more

Scientists ‘reprogram’ mouse fat cells into clinically useful stem cells

July 27, 2010

Australian scientists from the Monash Institute of Medical Research have reprogrammed adult mouse fat cells and neural cells to become stem cells that can differentiate into a variety of different cells (pluripotency).

The induced pluripotent stem cells (iPS) are nearly identical to the naturally occurring pluripotent stems cells, such as embryonic stem cells, which are highly pluripotent, in short supply and their access restricted in the U.S.

“Induced… read more

Scientists restore walking after spinal cord injury

January 7, 2008

A UCLA study shows that the central nervous system can reorganize itself after spinal cord damage and follow new pathways to restore the cellular communication required for movement.

Scientists reveal driving force behind evolution

February 26, 2010

Scientists at the University of Liverpool have provided the first experimental evidence that shows that evolution is driven most powerfully by co-evolutionary interactions with other species, rather than adaptation to the environment.

The team observed viruses as they evolved over hundreds of generations to infect bacteria. They found that when the bacteria could evolve defenses, the viruses evolved at a quicker rate and generated greater diversity, compared to situations… read more

Scientists reveal millions of regulatory elements in human genome

October 20, 2011

Twenty-nine mammals, including the elephant, armadillo, two-toed sloth, hyrax, dog, cat, horse, and tenrec, have had their genomes  analyzed and compared (credit: Nick Dua, Broad Communications)

An international research team has mapped and compared the genomes of 29 mammals and found new regulatory elements in the human genome that govern how proteins are formed.

The researchers, led by Kerstin Lindblad-Toh of the Broad Institute in Cambridge, Mass. and Uppsala University in Sweden, said the findings help us understand how mutations in human genes give rise to diseases.

Scientists reveal secret of girl with ‘all seeing eye’

July 21, 2009
MRI scan shows how the retinal optic nerve has connected to the left hemisphere of the brain

a girl’s brain had rewired itself to process information from the right and left visual fields in spite of her not having a whole brain at birth, University of Glasgow researchers have found.

Prime factors: long telemere length (pre-age 100) and low inflammation
August 6, 2015

Telomere length in study participants up to 115 years of age. Leukocyte telomere length vs age is shown for males (blue or cyan) and females (green or red). Centenarians, (semi-)supercentenarians, and centenarian offspring are shown in blue (males) or red (females), respectively. Unrelated participants younger than 100 years are indicated in cyan (males) or green (females). Regression lines belonging to these groups are indicated by the same colour. (credit: Yasumichi Arai et al./EBioMedicine)

Scientists say they have cracked the secret of why some people live a healthy and physically independent life over the age of 100: keeping inflammation down and telomeres long.

Newcastle University’s Institute for Ageing in the U.K. and Keio University School of Medicine note that severe inflammation is part of many diseases in the old, such as diabetes or diseases attacking the bones… read more

Scientists revolutionize creation of genetically altered mice to model human disease

May 6, 2013


Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.

“This new method is a game changer,” says Jaenisch, who is also a professor of biology at MIT. “We can now make a… read more

Scientists rewriting the genetic code

July 24, 2001

Scientists are taking the first steps toward creating alternative life forms — organisms that use a genetic code different from the one used by all other creatures on earth.
Scientists hope that such organisms can be used to study biochemical processes in new ways and to produce new medical or electronic materials that cannot now be made by living things.

The research goes well beyond current genetic engineering, which… read more

Scientists Say a Quest for Clean Energy Must Begin Now

November 1, 2002

Meeting the world’s rising energy needs without increasing global warming will require a research effort as ambitious as the Apollo project to put a man on the moon, a diverse group of scientists and engineers said in Science magazine today.
