On April 1st this year, a team of scientists led by NASA’s Jet Propulsion Laboratory posted a proposed new message to be sent to prospective intelligent extraterrestrials. The coincidence of April Fool’s Day in this case should be ignored. This actually is very real. The rationale for the message can be found in an article entitled, “A Beacon in the Galaxy: Updated Arecibo Message for Potential FAST and SETI Projects,” which has been submitted to the journal Galaxy and is currently posted on a pre-print server for review.

The article title includes the terms FAST and SETI. If you are not familiar with FAST, the acronym stands for the Five-Hundred-meter Aperture Spherical Telescope being built in China (see picture above) that will be the largest parabolic radio telescope in the world and capable of intercepting the faintest radio signals from across the Universe. SETI, the Search for Extraterrestrial Intelligence, is far better known and was featured prominently in the science fiction movie, Contact, based on a Carl Sagan novel.

What kind of message is being sent? And how will intelligent aliens be able to decipher it? Since the first radios and television signals were broadcast, humanity has been streaming information into outer space with no thought of how the information would be perceived by an intelligent technically advanced civilization on the receiving end. And even before radios, sending a message to intelligent aliens was proposed. In the early 1800s an Austrian astronomer wanted to carve out a geometric pattern of trenches in the Sahara Desert, fill them with kerosene and then light it all up tobe a beacon for any aliens living nearby.

Oil and gas wells no longer in use could be the answer.

NREL researchers Chad Augustine (left) and David Young, along with former colleague Henry Johnston, have been examining the idea of using depleted oil and gas wells as a reservoir for the storage of natural gas. The gas can then be released, as needed, to spin a turbine and generate electricity. Photo by Werner Slocum, NREL.

Chad Augustine and his colleagues at the National Renewable Energy Laboratory (NREL) see opportunity where others might simply see a hole in the ground.

Renting space and IP addresses on a public server has become standard business practice, but according to a team of Penn State computer scientists, current industry practices can lead to “cloud squatting,” which can create a security risk, endangering sensitive customer and organization data intended to remain private.

Cloud squatting occurs when a company, such as your bank, leases space and IP addresses—unique addresses that identify individual computers or computer networks—on a public server, uses them, and then releases the space and addresses back to the public server company, a standard pattern seen every day. The public server company, such as Amazon, Google, or Microsoft, then assigns the same addresses to a second company. If this second company is a bad actor, it can receive information coming into the address intended for the original company—for example, when you as a customer unknowingly use an outdated link when interacting with your bank—and use it to its advantage—cloud squatting.

“There are two advantages to leasing server space,” said Eric Pauley, doctoral candidate in computer science and engineering. “One is a cost advantage, saving on equipment and management. The other is scalability. Leasing server space offers an unlimited pool of computing resources so, as workload changes, companies can quickly adapt.” As a result, the use of clouds has grown exponentially, meaning almost every website a user visits takes advantage of cloud computing.

The world is aging, and with age comes vision decline. New research may have found how to improve eyesight in an accessible way.

A banking trojan for Android that researchers call Fakecalls comes with a powerful capability that enables it to take over calls to a bank’s customer support number and connect the victim directly with the cybercriminals operating the malware.

Disguised as a mobile app from a popular bank, Fakecalls displays all the marks of the entity it impersonates, including the official logo and the customer support number.

When the victim tries to call the bank, the malware breaks the connection and shows its call screen, which is almost indistinguishable from the real one.

A variant of the CTLA-4 gene associated with autoimmune disease was found to be more frequent in non-small cell lung cancer (NSCLC) patients who experienced an exceptionally high response to anti-PD-1 immunotherapy and higher immune-related side effects than in a comparable cohort of lung cancer patients and healthy individuals, according to data presented during the AACR Annual Meeting 2022, held April 8–13.

“Inhibitors of the immune checkpoint proteins PD-1/PD-L1 have transformed the cancer treatment landscape. However, there remains large variability in response and unpredictable adverse events, including autoimmune reactions, in NSCLC patients who undergo this treatment,” said presenter India Allen, BSc, from the Garvan Institute of Medical Research, St Vincent’s Medical School, UNSW, Australia. “There are currently limited biomarkers to effectively predict this variability, and the extent to which a patient’s genetic makeup contributes to response is not well understood.”

The occurrence of immune-related adverse events (irAEs)—the side effects that arise in response to activation of the immune system by immunotherapy—is known to correlate with higher response to anti-PD-1 therapy and improved outcomes in NSCLC patients.

Payments company Mastercard has applied for at least 15 crypto-and metaverse-related trademarks, according to data from the United States Patent and Trademark Office payments giant Mastercard filed 15 cryptocurrency, metaverse and NFT related trademark applications on April 4th.

Mastercard’s applications include trademarks for virtual cards and payments in the metaverse, an application to create NFTs, an NFT marketplace, as well as a marketplace for crypto assets in general.

“Provision of an online marketplace for buyers and sellers of downloadable digital goods and media authenticated by non-fungible tokens (NFTs),” one of Mastercard’s applications, serial number 97,346,029, read.

My guest today is Dr. Thayne Currie, an astrophysicist at NASA-Ames Research Center and the Subaru Telescope. Dr. Currie was part of a team that directly imaged a newly-forming planet, providing evidence of another way large planets can form, and could have formed here in the Solar System.

It’s not quite the mythical fountain of youth but it is, perhaps, a start: Scientists have managed to engineer human skin cells to reverse 30 years of aging, resetting them to a much more youthful state in terms of certain molecular measurements.

While it’s very early days for the research – so we shouldn’t get carried away too quickly – the technique could play a major part in efforts to produce rejuvenative medicine that’s able to undo some of the damaging consequences of our bodies getting older.

What makes the research particularly notable is that the skin cells were reprogrammed to be biologically younger while still keeping some of the functionality that made them skin cells in the first place.
