Lab-tailored enzyme shows promise as a new and powerful treatment against tobacco addiction

Science to the rescue.

Newly-devised molecule might help people quit smoking by blocking nicotine break-down

An… unusual take on the issue, to say the least. But in theory, it should work.

Genetic-scissor enzyme eliminates HIV completely in mice trials

A new gene-snipping enzyme was successful in removing strands of HIV genetic material in mice trials. If the enzyme can prove its reliability in human trials it might revolutionize how we fight the virus forever.

Self assembling nano material brings us tangibly close to water-powered cars

Indiana University scientists have built a highly efficient bio-material that can serve as a catalyst for hydrogen production. This material takes us halfway towards the long sought-after “holy grail” of splitting water to make hydrogen and oxygen for fueling cheap and efficient cars that run on water.

New enzyme could be used as an insulin alternative, to treat diabetes and obesity

University of Montreal Hospital Research Centre (CRCHUM) scientists have identified a new enzyme that could protect the body from toxic levels of intra-cell sugar. When there is too much sugar in the body it gets processed to glycerol-3-phosphate, a buildup of which can damage internal organs. The team behind the study proved that G3PP is able to extract excess sugar from cells.

Genetically modified apples don’t turn brown when sliced or bruised

The US government approved a genetically modified apple that doesn’t turn brown when bruised or sliced. While most genetic alterations of plants involve making these more resilient to pests or yield more, the non-browning apples were made out of cosmetic considerations. Of course, the apples will still rot and eventually get brown, but in time and not so easily when stressed (cell rupture). But despite the government approval, voices run rampant against the genetically modified fruit from behalf of anti-GMO groups, as well as rivaling food companies.

New process turns CO2 into alcohol using enzymes

We’ve previously told you how our ancestors’ adaptation to metabolizing alcohol which first happened some 10 million years ago may have been essential to their survival. There’s more to it though. The same enzyme that metabolizes alcohol, dehydrogenase (ADH4), may be eventually used to transform CO2 into alcohol, which could be later used as a fuel, according to a paper

Acacia trees deal addiction to bodyguard ants

A strange evolutionary alliance between trees and the ants that guard them has a sinister explanation, a new study suggests, after studying ants hooked on nectar. Bodyguard ants and addiction In Central America, ants act as bodyguards for acacia trees, defending them not only from weeds, but also from animals, in exchange for accomodation and food – this has traditionally

‘Sprite’ and soda water best cures against hangover

Drinking until the early hours of dawn may be exhilarating for some, however the next day everything seems to tumble over as the mind is assaulted by a barrage of hangover attacks. There are a number of popular home-brewed remedies against hangover: eating eggs, sipping a bit of castor oil, Vitamin B effervescent pills, tomato sauce, work (or anything that

Cure for the hangover possibly found

In a promising discovery for students and party aninals all over the world, a team of researchers led by UCLA engineers has identified a method for speeding up the body’s reaction to alcohol consumption – practically elimining the hangover. Researchers take their hangovers really seriously – in a paper published online Feb. 17 in the peer-reviewed journal Nature Nanotechnology, Yunfeng

Scientists sober up mice with novel enzyme nano-parcels

A team of international researchers from US and China have employed a novel method to link enzymes together and then encapsulate them in a polymer shell. This enables the enzymes to work sequentially in chemical reactions, just like in nature. To illustrate their enzyme batch, a group of mice were intoxicated with alcohol and then injected with a packaged enzyme complex that

Genetic tweak makes plants produce enzyme-replacing drug

Culturing mammalian cells is currently the only way to make some complex proteins used in certain drugs; but growing such cultures is an extremely difficult and delicate job, because they can harbor human pathogens and must therefore be kept under strict temperature conditions. It’s a difficult job, but it’s definitely worth it; take a look at the rare lysosomal storage

Scientists prove ‘immortal worms’ can regenerate indefinitely and stay forever young

University of Nottingham scientists spurred a slew of debate in 2008 when they claimed their object of study, the planaria or “flatworm”, might actually be immortal, possessing an indefinite ability to regenerate its cells and thus practically never grow old. In fact, an important distinction must be made, it’s not that the flatworm never grows old that’s interesting, it’s the fact that

Enzyme allows mice to eat more, and gain less weight

Scientists have genetically engineered mice able to express a certain enzyme, which allows for an increased metabolic rate. The lab mice infussed with this enzyme in their fat tissue were able to eat more, but gain far less weight than their naturally bred brethren. It’s generally acknowledged that obesity and inflammation cause insulin resistance, however it’s not perfectly understood why

Gamers solve decade old HIV puzzle in ten days

Scientists from the University of Washington have been struggling for the past decade to decipher the complex structure of an enzyme that exhibits  behavior similar to that of an enzyme key in the development of AIDS from an HIV infection, and which might hold a critical role in building a cure for the disease. Gamers playing spatial game Foldit have

How aging can be cured in the future – a scientist’s view

If we’re to guide ourselves after Aubrey de Grey‘s telling, according to his predictions the first person who will live to see their 150th birthday has already been born, and as science advances along the decades at the current pace it does, he claims people born soon after the latter mentioned birthday will live to be 1,000. “I’d say we

Increasing brain enzyme may slow Alzheimer’s

The fight against Alzheimer’s is a harsh and rugged one, and despite numerous advancements, there still isn’t a definitive cure for the disease around – or a fail proof way to detect it in the early stages.. Still, if you can’t defeat it, it’s still better to slow it down a little, and that’s exactly what researchers from Los Angeles

New Enzyme Could Revolutionize Plastic Production

Polymethyl methacrylate (PMMA for short) is a thermoplastic and transparent plastic that’s called acrylic glass for short. In the not so distant future it could be made from natural products such as sugars, alcohols or fatty acids. This process is much more environmentally friendly than the process used now. PMMA is manufactured by polymerising methyl methacrylate (MMA). However, scientists at

Major advance in computational chemistry: Designer Enzymes

In what is a great leap for science, scientists from UCLA and the University of Washington have succeeded in creating “designer enzymes,” a major milestone in computational chemistry and protein engineering. The two groups were led by UCLA’s chemistry professor Kendall Houk and Washington’s biochemist David Baker. Designer enzymes will have applications for defense against biological warfare, by deactivating pathogenic
