Google plans to add a Zoom-like gallery view to its business- and education-focused Meet videoconferencing service and let users start calls and join meetings right from Gmail, Google’s GM and VP of G Suite Javier Soltero told Reuters in an interview. The additions come amid huge growth for Meet as families, students, and workers use the service while at home due to the COVID-19 pandemic.

The upcoming gallery view will let users display up to 16 meeting participants in one frame, according to Reuters. That functionality is coming later this month, said Soltero. Zoom’s gallery view, by contrast, lets you see the thumbnails of up to 49 people in one screen, if you have a powerful enough CPU to display them all.

State and federal governments are working on plans to “reopen” the country. But new models suggest that we will may not live normally for years.

A new study reviews the state of the art of aging biomarkers and explores the future development of even better ways of measuring biological age.

The need for better aging biomarkers

Human life expectancy has been increasing throughout the 20th and 21st centuries due to improvements such as better access to healthcare and sanitation, lower child mortality, reduction of poverty, and better education access.

Scientists at Tokyo Institute of Technology (Tokyo Tech) have generated low-cost extreme ultraviolet (EUV) light by creating tin thin-film spheres using a polymer electrolyte “soap bubble” as a template and irradiating it with a laser.

The team from Tokyo Tech, working with colleagues from University College Dublin, set out to find efficient, scalable, low-cost laser targets that could be used to generate EUV. The scientists created a tin-coated microcapsule or “bubble” — a low-density structure weighing as little as 4.2 nanograms and with a high level of controllability. For the bubble, they used polymer electrolytes, which are a dissolution of salts in a polymer matrix. The salts act as surfactants to stabilize the bubble.

LONDON (Reuters) — A million doses of a potential COVID-19 vaccine being developed by British scientists are already being manufactured and will be available by September, even before trials prove whether the shot is effective, the team said on Friday.

The Seattle woman was the first to receive this vaccine.

The new diagnostic tool, Detectr, shows promise in rapidly detecting COVID-19.

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Cooling atoms to ultracold temperatures is a routine task in atomic physics labs, but molecules are a trickier proposition. Researchers in the US have now used a widely-applicable combination of methods to make molecules colder than ever before – a feat that could pave the way for applications in areas as diverse as high-temperature superconductivity and quantum computing.

In everyday life, we do not see the bizarre effects of quantum mechanics because the quantum states of the particles around us are constantly collapsing, or decohering, as they interact. At temperatures near absolute zero, however, some identical particles will simultaneously occupy the lowest energy quantum state available. This phenomenon is known as quantum degeneracy, and it was experimentally demonstrated in 1995, when groups led by Eric Cornell and Carl Wieman (then at the University of Colorado, Boulder) and Wolfgang Ketterle of the Massachusetts Institute of Technology (MIT) created the first Bose-Einstein condensates (BECs) with rubidium and sodium atoms, respectively.

Other groups have subsequently made condensates using other atomic species, and various techniques have been developed to cool atoms to quantum degeneracy. In one of the simplest methods, a sample of atoms is confined in a magnetic or optical trap. Hotter atoms with more kinetic energy are more readily able to escape, or evaporate, from this trap, so the remaining atoms become cooler. In another method, known as sympathetic cooling, one type of atom is cooled directly and allowed to thermalize with atoms of another type, thereby cooling them by extracting their kinetic energy.
