Abnormal IVF embryos can now be predicted within 30 hours of development. The chromosomal abnormalities that affect at least half of the human embryos created for in vitro fertilisation (IVF) can now be predicted within the first 30 hours of development at the cell-1 stage - days before they need to be transferred into a woman's body.

Abnormal IVF embryos can now be predicted within 30 hours of development

The discovery could help improve the odds of an IVF embryo developing into a pregnancy. Right now, the global percentage for a successful pregnancy from an IVF embryo sits between 30 and 35 percent. The reason such low odds exist is that between 50 and 80 percent of all embryos created for IVF end up developing a severe chromosomal abnormality that can dramatically increase their chances of being miscarried, and but we have no way of knowing which ones before they need to be implanted.

Transgenic Pigs Shatter Transplant Records. With the financial aid of a biotechnology executive whose daughter may need a lung transplant, U.S. researchers have been shattering records in xenotransplantation, or between-species organ transplants.

The researchers say they have kept a pig heart alive in a baboon for 945 days and also reported the longest-ever kidney swap between these species, lasting 136 days.

A single taste is enough to make you unforgettably familiar with the effects of wasabi, but why does it happen?

This Is Why Wasabi Sets Your Mouth On Fire

The reason is this protein right here — and it has some major implications for how we treat pain. David Julius and Yifan Cheng of The University of California San Francisco created this 3D model — the first ever — of receptor TRPA1, better known as the "wasabi receptor", the protein responsible for giving wasabi its bite. Scientists Have Transplanted Mammoth DNA Into Elephant Cells. A lot of people seem to be under the misconception that scientists want to clone mammoths to restore a wild population.

Scientists Have Transplanted Mammoth DNA Into Elephant Cells

No scientist is advocating for that; their environment doesn't exist any more. The first cloned mammoths would be used purely for research, and we're quite a ways off from mass cloning. One day we could borrow ‘antifreeze’ proteins from ticks to resist cold. These pests might be good for something after all.

One day we could borrow ‘antifreeze’ proteins from ticks to resist cold

(AP Photo/Victoria Arocho, File) Feeling a bit nippy? For now you'll have to stick to your hat and scarf to warm up, but one day some antifreeze proteins from a fish or a tick might do the trick. In a preliminary study published Wednesday in PLOS ONE, researchers report using specially bred mice -- ones spliced with the genes that give ticks antifreeze cells -- to show that mammals can benefit from the proteins that other species use to keep from icing over.

Ticks aren't the only species with so-called antifreeze proteins, which help keep creatures that don't moderate their own body temperatures from ending up with frozen cells (or, in some cases, just keep that freezing from having harmful effects) by preventing the formation of ice crystals inside tissue.

My wife would rather stab aforementioned pipet into her eye than undertake a trip like this but man, i'd love to do that some day! Flagged To make it extra awesome, I jump on an off-road dirt bike (no lights) and go ride out on the hardpan during these stary nights. Away from the campfire, and out in the middle of the flats there is zero point of reference while you ride, just a lighter colored expanse below you with tiny gypsum crystals that reflect the starlight above.

Man With Severed Spinal Cord Walks Again After Cell Transplant. A man paralyzed for two years is now walking again, albeit with a frame, after a transplant to his spine.

Man With Severed Spinal Cord Walks Again After Cell Transplant

The treatment, to be published in this month's Cell Transplantation, has been under discussion for a while, but has only now shown success. In 2010, Darek Fidyka was repeatedly stabbed, rendering him paralyzed from the chest down. Fortunately, however, his nose was unscathed. A Medical First: Woman Successfully Gives Birth With A Donated Womb. "women the world over with missing or non-functional uteruses" I had no idea this was even a thing.

A Medical First: Woman Successfully Gives Birth With A Donated Womb

I'm one of those women thanks to a massive fuck-up by a NYC gynecologist when I was 19. My niece has this same syndrome. No uterus, but she does have ovaries, so she went through puberty. Broad-Spectrum Anti-biofilm Peptide That Targets a Cellular Stress Response. Abstract Bacteria form multicellular communities known as biofilms that cause two thirds of all infections and demonstrate a 10 to 1000 fold increase in adaptive resistance to conventional antibiotics. Currently, there are no approved drugs that specifically target bacterial biofilms. Here we identified a potent anti-biofilm peptide 1018 that worked by blocking (p)ppGpp, an important signal in biofilm development.

At concentrations that did not affect planktonic growth, peptide treatment completely prevented biofilm formation and led to the eradication of mature biofilms in representative strains of both Gram-negative and Gram-positive bacterial pathogens including Pseudomonas aeruginosa, Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, methicillin resistant Staphylococcus aureus, Salmonella Typhimurium and Burkholderia cenocepacia.

The company is now bringing its medical testing technology to market—and it’s a game changer. Mathew Scott (hair and makeup by Raina Antle) Phlebotomy. Even the word sounds archaic—and that’s nothing compared to the slow, expensive, and inefficient reality of drawing blood and having it tested. As a college sophomore, Elizabeth Holmes envisioned a way to reinvent old-fashioned phlebotomy and, in the process, usher in an era of comprehensive superfast diagnosis and preventive medicine. Aging Successfully Reversed in Mice; Human Trials to Begin Next : Futurology. Crowdfunding rare disease research – one family at a time.

If one of your loved ones was sick, what would you be willing to do to help? For millions of Americans in the US, even though they would give up anything and everything, there is no way for them to help. For many rare diseases, because they are so rare, there are no therapies or even diagnostics. What is needed is research. However, very few people have the funding and the access to the technology needed to perform such a study. Non-profits and foundations have been a major force in pushing forward research, but for many rare diseases, no such groups exist.

Struggling with global developmental delays, Maya has not been able to speak, has had problems hearing, and has undergone many surgeries. Anti-aging formula slated to begin human trials. Things like Botox, hand creams, and hair dye exist to prolong the appearance of youth - but what if it could actually be achieved at the cellular level?

A collaboration of researchers from the United States and Australia might have done just that. A regular metabolic compound that has been administered to mice has been shown to not just boost muscle function, but actually reverse the affects of aging. The research was led by David Sinclair of the University of New South Wales and the results have been published in the journal Cell. A normal part of human aging involves senescence, which is a general wearing out of the body over time. Muscles begin to lose tone and become inflamed over time, and they also can develop insulin resistance. New Computer-Designed 'Drug' Prevents AIDS From Replicating.
