After a US Supreme Court draft decision on Roe v. Wade was leaked in May, Dr. Joshua Trebach noticed a disturbing turn in the online conversation around abortion.

“I started seeing things on social media, things like TikTok, Twitter, Facebook, Instagram, people saying ‘oh, if Roe v. Wade does get overturned, here are some secret, sneaky ways that you can drink some tea and have an abortion,’” Trebach said.

Now that Roe v. Wade has been overturned and some states are putting strict limits on abortions, there’s widespread confusion about whether the procedures are available and to whom. Physicians and poison control officials say they’re worried that people seeking abortions will turn to ineffective and dangerous methods shared online, potentially delaying or preventing safe, proven abortion care.

Researchers at Cornell University have come up with a novel biomaterial that can be used to create artificial skin capable of mimicking the behavior of natural human tissues.

Thanks to its unique composition, made up of collagen mixed with a ‘zwitterionic’ hydrogel, the team’s biohybrid composite is said to be soft and biocompatible, but flexible enough to withstand continued distortion. While the scientists’ R&D project remains ongoing, they say their bio-ink could one day be used as a basis for 3D printing scaffolds from patients’ cells, which effectively heal wounds in-situ.

“Ultimately, we want to create something for regenerative medicine purposes, such as a piece of scaffold that can withstand some initial loads until the tissue fully regenerates,” said Nikolaos Bouklas, one of the study’s co-lead authors. “With this material, you could 3D print a porous scaffold with cells that could eventually create the actual tissue around the scaffold.”

Because the heart, unlike other organs, cannot heal itself after injury, heart disease—the top cause of mortality in the U.S.—is particularly lethal. For this reason, tissue engineering will be crucial for the development of cardiac medicine, ultimately leading to the mass production of a whole human heart for transplant.

Researchers need to duplicate the distinctive structures that make up the heart in order to construct a human heart from the ground up. This involves re-creating helical geometries, which cause the heart to beat in a twisting pattern. It has long been hypothesized that this twisting action is essential for pumping blood at high rates, but establishing this has proven problematic, in part because designing hearts with various geometries and alignments has proven difficult.

Relatively new COVID-19 subvariant BA.5 takes some of Omicron’s worst traits—transmissibility and immune evasion—to a new level.

But it also combines them with a penchant for affecting the lungs reminiscent of the Delta variant that hit the U.S last summer and fall, according to two recent studies.

In the case of Delta, COVID tended to accumulate in and affect the lungs, potentially resulting in more severe disease. Until recently, a silver lining of Omicron has been its tendency to instead accumulate in the upper respiratory tract, causing symptoms more similar to a cold or the flu.

Researchers at Simon Fraser University have made a crucial breakthrough in the development of quantum technology.

Their research, published in Nature today, describes their observations of more than 150,000 silicon “T center” photon-spin qubits, an important milestone that unlocks immediate opportunities to construct massively scalable quantum computers and the quantum internet that will connect them.

Quantum computing has enormous potential to provide computing power well beyond the capabilities of today’s supercomputers, which could enable advances in many other fields, including chemistry, materials science, medicine and cybersecurity.

Researchers at the University of California, Davis, have been able to produce antibodies to the SARS-CoV-2 spike protein in hen eggs. Antibodies harvested from eggs might be used to treat COVID-19 or as a preventative measure for people exposed to the disease. The work was published July 9 in the journal Viruses.

“The beauty of the system is that you can produce a lot of antibodies in birds,” said Rodrigo Gallardo, professor in poultry medicine, Department of Population Health and Reproduction at the UC Davis School of Veterinary Medicine. “In addition to a low cost to produce these antibodies in hens, they can be updated very fast by using updated antigens to hyperimmunize hens, allowing protection against current variant strains.”

Birds produce a type of antibody called IgY, comparable to IgG in humans and other mammals. IgY does not cause allergy or set off immune reactions when injected into humans. IgY appears both in birds’ serum and in their eggs. As a hen lays about 300 eggs a year, you can get a lot of IgY, Gallardo said.

The daily figure in Tokyo grew by 8,537 from a week earlier to 16,878, marking a week-on-week increase for the 26th straight day.

Nearly two-and-a-half years since the coronavirus pandemic began, the most infectious and transmissible variant yet has arrived.

Repeated Covid-19 waves have left millions of people dead, with only vaccines helping to blunt the toll. Now the virus is spreading again — evolving, escaping immunity and driving an uptick in cases and hospitalizations. The latest version of its shape-shifting, BA.5, is a clear sign that the pandemic is far from over.

The newest offshoot of Omicron, along with a closely related variant, BA.4, are fueling a global surge in cases — 30% over the past fortnight, according to the World Health Organization (WHO).
