Cientista descobriram um método de criação de prole, sem a necessidade de um óvulo.
O experimento feito pela Universidade de Bath reescreve 200 anos de ensino de biologia.
Sempre se pensou que só um óvulo feminino poderia desencadear as mudanças em um espermatozóide necessário para fazer um bebê, porque um ovo formas de um tipo especial de divisão celular em que apenas metade do número de cromossomos são transitados.
BILHÕES de estrela mapeada.
Lançada 1000 dias atrás, Gaia iniciou os seus trabalhos científicos em Julho de 2014. Esta primeira versão é baseada em dados recolhidos durante seus primeiros 14 meses de varredura do céu, até setembro de 2015.
“O mapa mais bonito que estamos publicando hoje mostra a densidade de estrelas medidos por Gaia por todo o céu, e confirma que os dados coletados excelentes durante o seu primeiro ano de operações”, diz Timo Prusti, Gaia cientista do projeto na ESA.
Novo tecido utiliza do sol e vento para gerar energia.
Tecidos que podem gerar eletricidade a partir do movimento físico têm sido nas obras por alguns anos. Agora, pesquisadores da Georgia Institute of Technology ter tomado o próximo passo, o desenvolvimento de um tecido que pode colher simultaneamente energia de ambas sol e movimento.
A combinação de dois tipos de geração de energia elétrica em uma matéria têxtil abre o caminho para o desenvolvimento de peças de vestuário que poderiam fornecer a sua própria fonte de energia para alimentar dispositivos como smartphonr ou sistemas de posicionamento global.
South Korean-based company Rokit is a 3D printing manufacturer we’ve talked about on several occasions before. In February this year, they released Edison Invivo, a tissue engineering and bio-medical research 3D printer that uses a bio ink to produce cell structures in the form of organic tissue.
Now, as a constant innovator, Rokit is back with their latest and also the world first Multi-Use Hybrid Bio 3D printer — Rokit Invivo. What’s exciting is that this awesome bioprinter will be revealed very soon on 30th, September in the Digical Show held by London-based iMakr.
Interesting article overall; however, I have noticed many Gastric Bypass patients from my area who drastically loss weight quickly within a year had stomach, throat, and esophageal cancer. As with obesity being a trigger, I believe drastically changes with the body such as massive weight loss quickly could also trigger a cancer gene mutation. I would love to connect with others working of this type of research.
A review of more than a thousand studies has found solid evidence that being overweight or obese increases the risk for at least 13 types of cancer.
The study was conducted by a working group of the International Agency for Research on Cancer, part of the World Health Organisation.
Strong evidence was already available to link five cancers to being overweight or obese: adenocarcinoma of the esophagus, colorectal cancer, breast cancer in postmenopausal women, and uterine and kidney cancers.

Interesting read.
When Hippocrates first described cancer around 400 B.C., he referred to the disease’s telltale tumors as “karkinos” — the Greek word for crab. The “Father of Western Medicine” likely noted that cancer’s creeping projections mirrored certain crustaceans, and the tumors ‘ characteristic hardness resembled a crab’s armored shell.
Later, scientists added another attribute: Tumors are hypoxic. That is, they grow so large and dense that they exclude blood vessels, causing a lack of oxygen in their cores. But what role these characteristics play in the development of cancer has remained a mystery.
Moving possibly one step closer to an answer, scientists from Princeton University and the Mayo Clinic Cancer Center have found that, in breast cancer, tumor hardness and hypoxia trigger a biological switch that causes certain cells to embark on a cancer-promoting program. Reported Aug. 8 in an article in the journal Cancer Research, this biological switch is critical to a tumors’ ability to invade other tissue, a process called metastasis — and could offer a promising treatment target.
