The government of Odisha has approved the Biotechnology Policy 2024 to create a flourishing ecosystem for the biotech industry. This will further promote higher education, research & infrastructure development in the sector and strengthen the supportive ecosystem for innovation, incubation, investment, income & impact to build enterprises. Association of Biotechnology …

Catch 22

Chromosome 22 is one of the smallest of our 23 pairs of chromosomes. But we still don't know whether it is gene-rich. So far, the chromosome has been linked with schizophrenia, chronic myeloid leukaemia and trisomy 22, the second most common cause of miscarriages. At least 27 diseases involve some …

Feeling the heat

biotechnology giant Monsanto seems perpetually embroiled in controversies. While new research has revealed that the warm climates can affect the growth of Monsanto's herbicide-resistant soya beans, Granada Food Services, which runs the cafeteria at Monsanto's headquarters in London, has decided to remove all food that is genetically-modified (gm ) from …

BRAZIL

Government inspectors in Brazil are burning fields and seizing sacks of bio-engineered soybean seeds. Brazil is yet to approve the cultivation of these beans and has thus emerged as the world's premier source of the regular variety. So food companies, which use soybean oil or soybean meal in everything from …

Deciphered!

for the first time ever, an international team of researchers has deciphered the complete genetic code of a human chromosome revealing the existence of hundreds of genes hitherto unknown in humans. Researchers from the Wellcome Trust-funded Sanger Centre near Cambridge, uk, Keio University in Japan and us laboratories at the …

A North South conflict

biotechnology and bioresources are two issues that have been in conflict for a while. Biotechnology, proposed as "the technology of the next century', has its proponents in the developed countries and users in developing countries. But with companies in the North taking the bioresources from the South, patenting them and …

This and that...

it may seem surprising but the same genes or those with similar dna sequences play different roles in different organisms. Many of these are called

How Dolly was cloned

why are we reviewing a book on the history of molecular biology? Not because Michel Morange, who wrote it, is a professor of microbiology at the University of Paris VI and Ecole Normale superior, whatever that distinguished title means or because Matte Cob has done a great job of translating …

A mammoth clone?

it could be Jurassic Park come alive. An international team of scientists is preparing to excavate and clone a woolly mammoth

Going slow on terminators

Biotechnology giant Monsanto has said that it would not commercialise the so-called "terminator' gene technology. The technology prevents plants from producing fertile seeds, forcing farmers to buy more seed rather than using seed from the previous year's crop. In a letter to Gordon Conway, president of the Rockefeller Foundation, the …

Dealing with mutant genes

Jaques Fresco of Princeton University, New Jersey, USA, and his colleagues have found a cunning way to repair the mutation that causes sickle-cell anaemia. They have designed a DNA strand that hooks on to the mutant gene, b -globin. When exposed to radiation, a chemical called psoralen attached to the …

Brazil

A Brazilian judge has asked the Monsanto Company to shelve plans to launch sales of genetically modified (gm) soybeans this year. He further ruled that the biotechnology giant's local unit must perform a one-year environmental impact study before selling its transgenic crop in the country. "Whenever there is a potential …

How genes cheat

if there has been one major transformation over the past two decades in the way we look at evolution, it is the increasing trend to adopt a gene-centred view, instead of an individual-centred view or the old-fashioned

Genetically modified, and spreading

Cultivation of genetically modified (GM) crops is increasingly becoming popular. Supporters of biotechnology feel that GM crops are the answer to the problem of food security and will curb the excessive use of harmful chemical pesticides. Critics argue that GM crops could wreak havoc with the environment. They warn that …

MONEYMAKERS

CLONING TECHNOLOGY: Geron, the US-based biotechnology company specialising in embryo research has bought the Scottish cloning technology that led to Dolly the sheep. The company aims to clone patients' cells to produce specialised tissues for transplantation. Geron is issuing about US $28 million of new shares to buy Roslin Bio-Med, …

Express yourself

how does a body respond to changes in the surrounding environment, like a rise in temperature, for example?

Information superhighway...

electrical signals from genes travel along a dna information "superhighway', according to the findings of Jacqueline Barton and her team at the California Institute of Technology in Pasadena, usa . Moreover, the signals can course through distances required to affect gene activity along dna ( Chemistry & Biology , Vol …

Drugs aimed at specific genes

RESEARCHERS at the Stanford University of usa have shown, rather ingeniously, how a puzzling observation in molecular biology might be put to practical use in developing new drugs and finding specific genetic targets of drugs. The observation is one of so-called redundancy: in many organisms, and in respect to many …

Revising rules

the Japanese government is considering revising its guidelines on gene therapy. The present rules, which were introduced in 1994, limits researchers to its use only for treatment of terminal diseases such as cancer and aids . The move follows an application by researchers to Osaka University's ethics committee for permission …
