Dr. Vicki Fishlock — Amboseli Trust for Elephants — Conservation And Welfare Of Africas Elephants

Posted by in category: futurism

50+ Year Study Of The Life Cycle, Conservation And Welfare Of Africa’s Elephants — Dr. Vicki Fishlock, Ph.D., Resident Scientist, Amboseli Trust for Elephants.


Dr. Vicki Fishlock Ph.D. is a Resident Scientist, at The Amboseli Trust for Elephants (https://www.elephanttrust.org/), an organization that aims to ensure the long-term conservation and welfare of Africa’s elephants in the context of human needs and pressures, through scientific research, training, community outreach, public awareness and advocacy, and which is involved in the longest-running study of wild elephants in the world.

Hackers can mess with HTTPS connections

Posted by in categories: encryption, security

Typically abbreviated as TLS, Transport Layer Security uses strong encryption to prove that an end user is connected to an authentic server belonging to a specific service (such as Google or Bank of America) and not an impostor masquerading as that service. TLS also encrypts data as it travels between an end user and a server to ensure that people who can monitor the connection can’t read or tamper with the contents. With millions of servers relying on it, TLS is a cornerstone of online security.

In a research paper published on Wednesday, Brinkmann and seven other researchers investigated the feasibility of using what they call cross-protocol attacks to bypass TLS protections. The technique involves an MitM attacker redirecting cross-origin HTTP requests to servers that communicate over SMTP, IMAP, POP3, or FTP, or another communication protocol.

The main components of the attack are the client application used by the targeted end user, denoted as C; the server the target intended to visit, denoted as Sint; and the substitute server, a machine that connects using SMTP, FTP, or another protocol that’s different from the one serverint uses but with the same domain listed in its TLS certificate.

MIT Engineers Have Discovered a Completely New Way of Generating Electricity

Posted by in categories: nanotechnology, particle physics

MIT engineers have discovered a way to generate electricity using tiny carbon particles that can create an electric current simply by interacting with an organic solvent in which they’re floating. The particles are made from crushed carbon nanotubes (blue) coated with a Teflon-like polymer (green). Credit: Jose-Luis Olivares, MIT. Based on a figure courtesy of the researchers.

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment.

After 60 years, scientists are still trying to crack a mysterious serotonin-autism link

Posted by in categories: biotech/medical, neuroscience

The high levels of serotonin seen in the blood of some autistic people have confounded scientists for more than half a century. Despite so little progress, some researchers refuse to give up.

DNA Jumps Between Animal Species. No One Knows How Often

Posted by in categories: biotech/medical, evolution

Laurie Graham, a molecular biologist at Queen’s University in Ontario and lead author on the paper, knows she’s making a bold claim in arguing for the direct transfer of a gene from one fish to another. That kind of horizontal DNA movement once wasn’t imagined to happen in any animals, let alone vertebrates. Still, the more she and her colleagues study the smelt, the clearer the evidence becomes.

Nor are the smelt unique. Recent studies of a range of animals — other fish, reptiles, birds and mammals — point to a similar conclusion: The lateral inheritance of DNA, once thought to be exclusive to microbes, occurs on branches throughout the tree of life.

Sarah Schaack, an evolutionary genomicist at Reed College in Portland, Oregon, believes these cases of horizontal transfer still have “a pretty big wow factor” even among scientists, “because the conventional wisdom for so long was that it was less likely or impossible in eukaryotes.” But the smelt discovery and other recent examples all point to horizontal transfers playing an influential role in evolution.

How Taking Short Breaks May Help Our Brains Learn New Skills

Posted by in categories: health, neuroscience

Summary: The resting brain repeatedly and rapidly replays faster memories of what a person has recently learned and practiced. The more a person replays the memory during rest, the better they become during subsequent sessions where they practice their newly learned skill.

In a study of healthy volunteers, National Institutes of Health researchers have mapped out the brain activity that flows when we learn a new skill, such as playing a new song on the piano, and discovered why taking short breaks from practice is a key to learning.
