Could autonomous CubeSats someday be used for deep space exploration? This is what a recent demonstration by SpaceX’s Starling swarm of four CubeSats hopes to address as NASA announced the 10-month primary mission of the swarm successfully completed its primary mission objectives as part of multiple experiments. This demonstration holds the potential to help develop CubeSats capable of conducting deep space exploration missions without the need for constant communication with Earth as they could communicate with each other.

“The success of Starling’s initial mission represents a landmark achievement in the development of autonomous networks of small spacecraft,” said Roger Hunter, who is the Program Manager for NASA’s Small Spacecraft Technology Program (STTP) at NASA’s Ames Research Center. “The team has been very successful in achieving our objectives and adapting in the face of challenges.”

For the demonstration, the four CubeSats successfully studied the Earth’s ionosphere while communicating with each other regarding next steps for continued analysis. This provided the opportunity for each spacecraft to equally contribute to the mission while decreasing human involvement.

Immunotherapy is a form of cancer treatment that harnesses the immune system to recognize and target the tumor. In most cancers, the immune system fails to detect the rapid proliferation of tumor cells. Lack of immune cell detection is due to the tumor polarizing or reprogramming immune cells to promote cancer progression and suppress the immune system. This is done through variety of ways including the release of proteins or cytokines that direct immune cell development and function. Current immunotherapies target these polarized immune cells to switch them back toward an anti-tumor function. Although there are many ways to redirect immune cells to attack cancer, immunotherapies maintain limited efficacy due to the immunosuppressive mechanisms within the tumor microenvironment (TME). In addition, heightened toxicity associated with immunotherapy also pose challenges when prescribing treatments to patients.

One immunotherapy that has demonstrated significant promise in cancer patients is chimeric antigen receptor (CAR) T cells are immune cells within the body that are responsible for killing or lysing invading pathogens, including cancer. The immune system orchestrates a response by employing T cells to recognize an infection, in healthy individuals. In the context of cancer, T cells cannot recognize that the tumor is deleterious to the body. Therefore, CAR T cells are generated to reprogram the cell’s ability to recognize and lyse the tumor. CAR T cell therapy takes the patient’s T cells and engineers them to target specific surface markers on the tumor. They are then grown in a dish and expanded before being intravenously reinfused in the patient. CAR T cell therapy is commonly associated with lymphoma, but unfortunately neurotoxicity can be an adverse side effect which limits efficacy.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a security flaw impacting the Linux kernel to the Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation.

Tracked as CVE-2024–1086 (CVSS score: 7.8), the high-severity issue relates to a use-after-free bug in the netfilter component that permits a local attacker to elevate privileges from a regular user to root and possibly execute arbitrary code.

“Linux kernel contains a use-after-free vulnerability in the netfilter: nf_tables component that allows an attacker to achieve local privilege escalation,” CISA said.

A previously undocumented cyber espionage-focused threat actor named LilacSquid has been linked to targeted attacks spanning various sectors in the United States (U.S.), Europe, and Asia as part of a data theft campaign since at least 2021.

“The campaign is geared toward establishing long-term access to compromised victim organizations to enable LilacSquid to siphon data of interest to attacker-controlled servers,” Cisco Talos researcher Asheer Malhotra said in a new technical report published today.

Targets include information technology organizations building software for the research and industrial sectors in the U.S, energy companies in Europe, and the pharmaceutical sector in Asia, indicating a broad victimology footprint.

A small device senses sounds using a spiderweb-like design—a strategy that could lead to chip-size microphones that are less affected by thermal noise.

Experiments and numerical simulations indicate that randomly replacing a few nonmagnetic components with magnetic ones in a photonic alloy induces backscattering-free light propagation along its edge.

Blue energy has the potential to provide a sustainable alternative to fossil fuels. In simple terms, it involves harnessing the energy produced when the ions in a salt solution move from high to low concentrations.
