Based on analyses of deposits of pollen grains, it is possible that all of Sweden was virtually free of ice for long periods during the latest ice age

Bacteria For Better Ice Cream And Artificial Snow No Longer Depends On Trek To Poles
The search for a type of bacteria that creates better ice cream and artificial snow has suddenly become a lot easier, thanks to a discovery by Queen's University biologist Virginia Walker.

Old Bones Unearth New Date For Giant Deer's Last Stand
A new investigation into extinctions caused by climate change has revealed that the giant deer, previously thought to have been wiped out by a cold spell 10,500 years ago, instead survived well into the modern era.

One Small Carnivore Survived The Last Ice Age In Ireland
You may well ask the question, where did the animals and plants of modern day Ireland and Britain come from?

A Survivor In Greenland: A Novel Bacterial Species Is Found Trapped In 120,000-year-old Ice
Scientists has discovered a new ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland glacier at a depth of nearly two miles.

Scientists Use An 'Ice Lolly' To Find Polar Bacteria In Their Own Backyard
To study the bacteria which survive in extreme cold, scientists no longer have to go to extreme environments, such as Antarctic lakes and glaciers.

Bacteria In Ice May Record Climate Change
To many people, bacteria and climate change are like chalk and cheese: the smallest creature versus one of the biggest phenomena on earth.

Better antifreezes to preserve donor organs for transplantation
Chemists in Canada have developed a new approach for producing more effective medical antifreeze fluids for preserving kidneys, hearts, and other organs donated for transplantation.

Picking particles faster than one at a time
A new algorithm automatically and dependably selects images of molecules for 'crystallization in silico'

Biologists see combined structure of cold virus and receptor molecule
Biologists determined the combined structure of a common-cold virus attached to a molecule that enables the virus to infect its host, information that ultimately may help researchers develop methods for treating certain viral infections.

'Frozen pictures' allow far-reaching glimpse into the cell’s protein factory
The structure of the small ribosomal subunit has been determinded at the highest resolution ever achieved by a team of Weizmann Institute and Max Planck Society scientists.

Key progress by Weizmann scientists in the race to unravel ribosomal structure
A team of Weizmann Institute and Max-Planck Society scientists has determined the structure of the small ribosomal subunit at the highest resolution ever achieved, including the site where protein biosynthesis begins.

New insights into protein synthesis and Hepatitis C infections
Scientists have uncovered key new information towards understanding the crucial first step in protein synthesis, the process by which the genetic code, harbored within DNA and copied into RNA, is translated into the production of proteins.

In Vitro Evaluation of Frozen-Thawed Stallion Semen: A Review
The article reviews methods used for in vitro evaluation of sperm, with particular emphasis on frozen-thawed stallion sperm.

The use of a new miniature cryoprobe for ablation of bone tissue: In vivo assessment of the probe and application of the method to bone in a sheep model
In this study, cryoablation methodology was applied to bone and the cooling capacity of the probe was examined in vitro and in vivo.

Cryospray ablation (CSA) in the palliative treatment of squamous cell carcinoma of the esophagus
Endoscopic cryo spray ablation warrants further investigation as a palliative treatment modality for esophageal cancer. This is the first reported case in the medical literature.

Technique shows ratcheting motion of ribosomes
Using a technique called three-dimensional cryo-electron microscopy, researchers have detected a ratcheting rotation deep inside the cell's tiny protein-making "factory" at a key point in the protein construction process.

Zooming in on the protein-conducting channel
Researchers have gained the most detailed view yet of the heart of the translocon, a channel through which newly constructed proteins are inserted into the cell membrane.
