Mammals usually mate via penetrative sex‚ but researchers report Nov. 20 in the journal Current Biology that a species of bat‚ the serotine bat‚ (Eptesicus serotinus) mates without penetration. This is the first time non-penetrative sex has been documented in a mammal.

Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane.

The rising resistance of bacteria to antibiotics presents an escalating global health risk. Now‚ researchers at the Max Planck Institute for Terrestrial Microbiology in Marburg‚ Germany‚ have combined synthetic biology and artificial intelligence (AI) to develop a more efficient approach to finding and creating new antimicrobial peptides that are effective against a wide range of bacteria. Their paper is published in the journal Nature Communications.

RNA has been in the limelight for its starring role in cutting-edge vaccine technology‚ but RNA molecules are also key players in the inner workings of cells.

Proteins that form clumps occur in many difficult-to-treat diseases‚ such as ALS‚ Alzheimer's‚ and Parkinson's. The mechanisms behind how the proteins interact with each other are difficult to study‚ but now researchers at Chalmers University of Technology‚ Sweden‚ have discovered a new method for capturing many proteins in nano-sized traps. Inside the traps‚ the proteins can be studied in a way that has not been possible before.

An international team of astrophysicists‚ aerospace engineers and balloonists has found that data recovery capsules are a viable means of ensuring data integrity in the event of loss of flight capabilities or communications abilities in balloon-based telescope projects. In their paper published in a special issue of Aerospace‚ the group describes their test of four Data Recovery System (DRS) capsules containing 5 TB of telescopic data sent aboard a helium-filled‚ super-pressurized balloon.

Blazars belong to the family of active galactic nuclei called quasars. What differentiates them from quasars is that the flares ejected out of these active galactic nuclei are pointed toward the Earth. These flares contain high-energy cosmic rays which are released from the core of these galaxies as jets spanning many light years. Such cosmic rays can interact with photons to produce subatomic particles called neutrinos.

The only groups that enjoy more support than Hamas are the terror groups that have no aspiration to do anything other than kill Jews. Palestinians believe that there is no credible reason for anyone to support Israel.

The United Auto Workers (UAW) union said Monday that 64% of workers at the Detroit Three automakers voted to ratify new contracts.
