On Tuesday, Google announced AlphaGenome Atlas, a resource that attempts to predict the consequences of every possible single-base variant in the human genome. The human genome is about 3 billion bases long, so trying the other three DNA bases that don't appear in our reference genome means sending a total of 9 billion bases through AlphaGenome software.

AlphaGenome is designed to identify potential functions of non-coding DNA, which does not encode proteins but makes up the vast majority of the human genome. Some of this non-coding DNA is essential for controlling the activity of the protein-coding portion—it tells the cell where and when to make messenger RNAs, how to process them into mature protein-coding forms, and so on. But much of it appears to be little more than the remains of viruses and other molecular parasites.

Being able to identify the functional portion is very useful, as is having all the analysis done by a single software package. But until biologists start to use it heavily (assuming they do), it won't be clear what AlphaGenome offers beyond what we could have gotten out of its training data.

For several decades, paleontologists have described Miracinonyx trumani -- an extinct species of cheetah-like felid that roamed the North American prairies and steppe terrains more than 13,000 years ago -- as North America’s answer to the African cheetah (Acinonyx jubatus).

Neanderthals vanished roughly 42,000 years ago, but a piece of their biology appears to be quietly at work in some people today, according to a new study led by scientists from the Max Planck Institute for Evolutionary Anthropology.

A lot of the AI work in biology has been focused on designing proteins. That's partly because proteins do most of the business of life, catalyzing the interesting chemistry and structuring cells. So, figuring out how to make a new protein can mean directly tinkering with biochemistry, providing new and potentially useful functions.

Since the genetic code provides a layer of abstraction between DNA and proteins, it wasn't obvious what a model trained on DNA could do. Yet people went ahead and made a large genome model, and it turned out to be able to output DNA sequences that could encode functional proteins in bacteria and mimic the gene structures found in complex cells. Now, those same models have been used to output the genomes of viruses that infect bacteria.

This isn't science fiction—all the viruses the models created are closely related to an existing virus. But they do have some distinct features that would be challenging to evolve. And the researchers who did the work, based at Stanford University, suggest we may want to start thinking now about preparing for the potential that someone could develop a related AI that can design a virus that targets vertebrates.

More than 150 years after Charles Darwin first wondered whether certain sticky-leaved Saxifraga plants might be secretly carnivorous, Kunming Institute of Botany researcher Tao Deng and colleagues say they have finally confirmed it.

Se você costuma usar o aplicativo Relógio (Clock) em iPhones, iPads e Macs ou o Timers do Apple Watch para ativar alarmes ou timers, saiba que é possível identificá-los adicionando um nome (ou etiqueta, como a Apple chama).

Isso é muito útil para quem possui múltiplos alarmes/timers em ação e quer ter um controle sobre eles.

Neste artigo, ensinaremos como é simples adicionar uma etiqueta em cada um, veja só.

Como adicionar uma etiqueta a um alarme/timer pelo iPhone, iPad ou Mac

1. Com o app Relógio aberto, toque/clique na aba “Alarmes” ou “Timers”
2. No caso de alarmes, você pode criar um novo tocando no botão de “+” ou editar um existente tocando em cima dele.

3. Na seção “Etiqueta”, digite o nome que quiser.
4. Você também pode simplesmente fazer isso pela Siri, pedindo algo como:
   • “Crie um alarme de trabalho para amanhã às 7 da manhã.”
   • “Ative um timer de pizza para 2 minutos.”

Como adicionar uma etiqueta a um alarme pelo Apple Watch

1. Pressione a Digital Crown para abrir o seletor de apps e abra o Alarmes.
2. Crie um novo rolando até o fim da página e tocando no “+” ou simplesmente toque em cima de qualquer alarme criado.
3. Toque em “Etiqueta” e dê um nome a ele.

Como adicionar uma etiqueta a um timer pelo Apple Watch

1. Mantenha a Digital Crown pressionada por alguns segundos e diga algo como:
   • “Ative um timer de pizza para 2 minutos.”

2. O nome do timer aparecerá no Conjunto Inteligente (Smart Stack) e no próprio app Timers.

Com o aplicativo Pré-Visualização (Preview), usuários de iPhones, iPads e Macs podem facilmente preencher e assinar formulários, escanear documentos e fazer alterações em PDFs e imagens, por exemplo.

Para encontrar mais facilmente um arquivo, você pode renomeá-lo em alguns passos simples.

Veja, nos parágrafos a seguir, como fazer exatamente isso no seu dispositivo! 😉

Com o app Pré-Visualização aberto, faça um dos seguintes procedimentos:

• Toque e segure o dedo ou clique com o botão direito do mouse em cima do arquivo e escolha “Renomear”.

• Com o arquivo aberto, selecione a setinha ao lado do nome dele e renomeie-o (no iPhone/iPad, é preciso primeiramente tocar em “Renomear”). Se estiver no Mac, você também pode fazer a mesma coisa indo até Arquivo » Renomear…, na barra de menus.

Simples, né?!
