To function, each living cell needs both to build new and to degrade old or damaged proteins. To accomplish that, a number of intracellular systems work in concert to keep the cell healthy and from clogging up with damaged proteins. When proteins or peptides mutate, they can present major problems to the clearing up of the intracellular environment. In Huntington's disease (HD) the disease provoking mutation in the huntingtin gene eventually causes the cell to build up intranuclear and cellular inclusions of protein-aggregates, made up primarily of huntingtin.

Scientific analysis of limestone ossuaries (bone boxes) and physical evidence found in a 2,000-year-old tomb in Talpiot, Jerusalem, provide credible new information that the tomb once may have held the remains of Jesus of Nazareth and his family. A new Discovery Channel documentary THE LOST TOMB OF JESUS, from executive producer James Cameron and director Simcha Jacobovici, exclusively reveals what might be the greatest archaeological find in history. The film presents the latest evidence from world-renowned experts in Aramaic script, ancient DNA analysis, forensics, archaeology and statistics. Among the major discoveries chronicled in the program is new evidence that Jesus and Mary Magdalene, also known as "Mariamene e Mara," may have had a son named Judah.

The future of cancer detection and treatment may be in gold nanoparticles - tiny pieces of gold so small they cannot be seen by the naked eye. The potential of gold nanoparticles has been hindered by the difficulty of making them in a stable, nontoxic form that can be injected into a patient. New research at the University of Missouri-Columbia has found that a plant extract can be used to overcome this problem, creating a new type of gold nanoparticle that is stable and nontoxic and can be administered orally or injected.

Because gold nanoparticles have a high surface reactivity and biocompatible properties, they can be used for in vivo (inside the body) molecular imaging and therapeutic applications, including cancer detection and therapy.

Seafood allergy sufferers may soon be able to eat prawns without the fear of an adverse reaction. Chinese scientists have taken a promising step towards removing from prawns the proteins that cause an allergic response without resorting to genetic manipulation, reports Lisa Richards in Chemistry & Industry, the magazine of the SCI.

Li Zhenxing led the research at the Ocean University of China. The team revealed that treating prawns with a combination of heat and irradiation significantly reduced the level of reactive proteins called allergens. They took blood from patients with shrimp allergies, added samples of treated and untreated prawn, and measured how antibodies in the blood reacted.

Use of growth hormone to boost athletic performance can lead to diabetes, reports a study published ahead of print in the British Journal of Sports Medicine.

The study reports the case of a 36 year old professional body-builder who required emergency care for chest pain.

He had lost 40 kg in 12 months, during which he had also experienced excessive urination, thirst, and appetite.

He admitted to using anabolic steroids for 15 years and artificial growth hormone for the past three. He had also taken insulin, a year after starting on the growth hormone.

Once roofed by ice for millennia, a 10,000 square km portion of the Antarctic seabed represents a true frontier, one of Earth's most pristine marine ecosystems, made suddenly accessible to exploration by the collapse of the Larsen A and B ice shelves, 12 and five years ago respectively. Now it has yielded secrets to some 52 marine explorers who accomplished the seabed's first comprehensive biological survey during a 10-week expedition aboard the German research vessel Polarstern.

While their families at home in 14 countries were enjoying New Year's dinners, experts on the powerful icebreaking research ship were logging finds from icy waters as deep as 850 meters off the Antarctic Peninsula – an area rapidly changing in fundamental ways.
