Judge Nullifies Human Gene Patents

genes

A federal judge on Monday nullified patents associated with human genes known to detect early signs of breast and ovarian cancer.

It was the first time a federal court has invalidated a patent on genes. The American Civil Liberties Union, which brought the case, said the New York federal court decision “calls into question the validity of patents now held on approximately 2,000 genes.”

U.S. District Judge Robert Sweet agreed with the civil rights group that the patents were invalid because they covered the most basic element of every person’s individuality. “Products of nature do not constitute patentable subject matter absent a change that results in the creation of a fundamentally new product,” Sweet wrote in a 152-page opinion.

The lawsuit claimed the patents were so broad they barred scientists from examining and comparing the BRCA1 and BRCA2 genes at the center of the dispute. The patents issued more than a decade ago covered any new scientific methods of looking at these human genes that might be developed by others.

Zebrafish Regenerative Ability May Help Humans

Biologists have discovered a molecular circuit breaker that controls a zebrafish’s remarkable ability to regrow missing fins, according to a new study from Duke University Medical Center.

Tiny wonders of the aquarium world, zebrafish can regenerate organs and tissues, including hearts, eye parts and fins. When a fin is lost, the fish regenerates a perfect copy in two weeks by orchestrating the growth of many tissue types, including bone, nerves, blood vessels, connective tissue and skin.

Scientists hope that understanding how zebrafish repair themselves will lead to new treatments for human conditions caused by damaged tissue, such as heart failure, diabetes and spinal cord injuries.

Pet dog to be cloned by Korean biotech

A South Korean biotech company has announced it will, for the first time ever, commercially clone a pet dog, according to reports coming out of the country.

RNL Bio said last week that it received an order from Californian Bernann McKunney, to clone her deceased pet pitbull, Booger, to the tune of $150,000. Booger died in 2005, but not before McKinney had tissue from his ear preserved.

The Korean company told the BBC that the cloning will take place at Seoul National University (SNU), where the first dog, Afghan hound Snuppy, was successfully cloned as a proof of concept in 2005. The SNU team that will recreate Booger is headed by Lee Byeong-chun, who was a colleague of Hwang Woo-suk, the disgraced Korean stem cell scientist who admitted fabricating data on human embryonic stem cell lines in 2006. Hwang’s dog cloning work, however, was determined to be legitimate, and the SNU team went on, after Hwang’s departure from the university, to successfully clone wolves.

Human culture subject to natural selection, Stanford study shows

The process of natural selection can act on human culture as well as on genes, a new study finds.

Scientists at Stanford University have shown for the first time that cultural traits affecting survival and reproduction evolve at a different rate than other cultural attributes. Speeded or slowed rates of evolution typically indicate the action of natural selection in analyses of the human genome.

This study of cultural evolution, which compares the rates of change for structural and decorative Polynesian canoe-design traits, is scheduled to appear Tuesday, Feb. 19, in the online Proceedings of the National Academy of Sciences.

“Biological evolution of inherited traits is the essential organizing principle of biology, but does evolution play a corresponding role in human culture”” said Jared Diamond, a professor of geography at the University of California-Los Angeles and author of Guns, Germs and Steel. “This paper makes a decisive advance in this controversial field.”

Geneticist sentenced in art case

A geneticist was sentenced to one year of unsupervised release (no jail time) and a $500 fine for supplying bacteria to an artist, according to the Buffalo News, bringing to an end a well-publicized case that began more than three years ago.

Robert Ferrell, based at the University of Pittsburgh, pled guilty in October to a misdemeanor, after he supplied Steven Kurtz with bacteria for use in biotechnology art projects.

The men were originally charged with mail and wire fraud in connection with Ferrell’s purchase of samples of two common bacteria, Serratia marcescens and Bacillus atrophaeus, for Kurtz.

Ferrell and Kurtz were indicted in June, 2004.

Scientists breed world’s first mentally ill mouse

Scientists have created the world’s first schizophrenic mice in an attempt to gain a better understanding of the illness.

It is believed to be the first time an animal has been genetically engineered to have a mental illness. Until now they have been bred only for research into physical conditions such as heart disease. It will allow researchers to study the disease and develop treatments using a limitless supply of laboratory animals.

Scientists find cultural differences among chimpanzee colonies

Socially-learned cultural behaviour thought to be unique to humans is also found among chimpanzees colonies, scientists at the University of Liverpool have found.

Historically, scientists believed that behavioural differences between colonies of chimpanzees were due to variations in genetics. A team at Liverpool, however, has now discovered that variations in behaviour are down to chimpanzees migrating to other colonies, proving that they build their ‘cultures’ in a similar way to humans.

Sea Cucumber Protein Used To Inhibit Development Of Malaria Parasite

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to new research. Researchers say this development is a step towards developing future methods of preventing the transmission of malaria.

Malaria is caused by parasites whose lives begin in the bodies of mosquitoes. When mosquitoes feed on the blood of an infected human, the malaria parasites undergo complex development in the insect’s gut. The new study has focused on disrupting this growth and development with a lethal protein, CEL-III, found in sea cucumbers, to prevent the mosquito from passing on the parasite.

Stem Cell Breakthrough Is Like ‘Turning Lead Into Gold’

In an unprecedented feat of biological alchemy, researchers have turned human skin cells into stem cells that hold the same medical promise as the controversial embryonic stem cells.

Scientists believe stem cell research will be able to cure numerous diseases and regenerate failing bodies. The new technique, however, doesn’t require the destruction of embryos, or use human eggs or cloning. Thus, it sweeps aside the ethical objections to stem-cell research.

Even in a field accustomed to breathless proclamations of breakthroughs, the research—published Tuesday in two papers appearing in the journals Cell and Science—has provoked wonder among many scientists. They say the advance is more significant to medical research than last week’s announcement that scientists had cloned the first monkey embryo.

A Programming Language for DNA

Researchers have made an important leap in designing DNA-based circuits, reports this week’s Science. They’ve created the first system that allows amplification of desired DNA sequences without using enzymes—a step towards creating artificial biochemical circuits inside cells.

“They’ve begun to develop a programming language, a software, for DNA,” said Andrew Ellington of the University of Texas at Austin. The work is “a significant advance over previous [attempts],” he added.

Scientists have previously used DNA to build synthetic biochemical circuits. But these networks have generally only been designed to perform one task. “These were machines that carried out a particular function or solved a particular problem,” Ellington told The Scientist.

In the new work, “we show a method of designing them generally so that it can be applied basically to any sequence you want,” said first author David Yu Zhang of the California Institute of Technology in Pasadena.

Cyanobacteria that Crap Ethanol

cyanobacteria ethanol

Pengcheng (Patrick) Fu, a professor of bioengineering at the University of Hawai’i, has devised a way to turn carbon dioxide into ethanol by using a combination of cyanobacteria and sunlight.

By successfully transforming two genes from a fellow cyanobacterium, Fu and his colleagues were able to engineer a specific strain of Synechocystis that emits ethanol as waste upon using carbon dioxide and sunlight. With his new startup – SUNOL Biotechnology (that we encountered at Wired Nextfest) – Fu hopes to be able to build a large-scale ethanol plant within the next 2-3 years.

In addition to removing carbon dioxide directly from the atmosphere, Fu envisages that to get the carbon dioxide it needs, the system could even pull the gas out of the emissions of power plants or other carbon dioxide producers. That would prevent carbon dioxide release into the atmosphere, where it has been implicated as a major cause of global warming.”

Smithsonian Helps Lead Effort to ‘Barcode’ World’s Species

barcode tattooSmithsonian researchers are among the leaders in a worldwide effort to revolutionize the way scientists identify species in the laboratory and in the field with a technique called DNA barcoding. Similar to the barcode that identifies an item at the grocery store, a DNA barcode is used to identify and distinguish biological species.

This month, scientists are gathering in Taiwan for the Second International Barcode of Life Conference (Sept. 17-21). They will discuss potential applications for using DNA barcodes, including food safety, disease prevention and better environmental monitoring. There are now more than 280,000 DNA barcode records representing about 31,000 species.

The Genetics of Loneliness

Changes in the immune system may explain why social factors like loneliness are linked to an increased risk of heart disease, viral infections and cancer.

It’s already known that a person’s social environment can affect their health, with those who are socially isolated—that is, lonely suffering from higher mortality than people who are not.

Now, in the first study of its kind, published in the current issue of the journal Genome Biology, UCLA researchers have identified a distinct pattern of gene expression in immune cells from people who experience chronically high levels of loneliness. The findings suggest that feelings of social isolation are linked to alterations in the activity of genes that drive inflammation, the first response of the immune system. The study provides a molecular framework for understanding why social factors are linked to an increased risk of heart disease, viral infections and cancer.

Ministers To Allow Chimera Creation

chimeraMinisters have bowed to pressure to allow the creation of human-animal hybrid embryos for research.

When the ban was proposed last year there were fears among scientists it would hamper medical breakthroughs.

Hybrid embryos will only be allowed for research into serious disease and scientists will require a licence.

Scientists welcomed the proposals put forward in the draft fertility bill, but opponents questioned the ethics of using human cells in this way.
